摘要： This invention relates to a book-sized, self-contained analog computer, organized to enable an inexperienced person to program readily a differential equation. In this computer permanent circuits are either exposed or indicated as solid lines. Connections between terminals available for patching by the user are shown as dashed lines, so that with the aid of an instruction manual even a beginner can implement quickly a differential equation at the first try.Being small in size, this computer can be placed beside a student's computation sheets to be used for checking solutions arrived at by other means. Because components are inserted by the user without soldering, a user can modify a circuit quickly to suit his needs. As an example, a summing amplifier can be modified to perform the functions of a modified differentiator, an absolute value circuit or a switching circuit, to name a few, enabling this computer to have the capacity of one having twice the number of computing components whose components are not modifiable. This computer also has been designed with features enabling it to be less dependent on an oscilloscope. A peak voltage detector and an oscillation counter enable a student to determine the damping ratio of an underdamped second order system without the assistance of an oscilloscope.
摘要翻译：本发明涉及一种书本尺寸的独立模拟计算机，其被组织为使得经验不足的人能够容易地编程微分方程。在该计算机中，永久电路被暴露或以实线表示。可用于用户修补的终端之间的连接被显示为虚线，使得借助于指令手册，即使初学者也可以在第一次尝试时快速实现微分方程。体积小，这台电脑可以放在学生的计算表旁边，用于检查通过其他方式到达的解决方案。由于用户没有焊接插入组件，所以用户可以快速修改电路以适应他的需要。作为示例，可以修改求和放大器以执行修改后的微分器，绝对值电路或开关电路的功能，以使该计算机的容量为计算部件数量的两倍组件不可修改。该计算机还具有使其能够较少依赖于示波器的功能。峰值电压检测器和振荡计数器使学生能够在没有示波器帮助的情况下确定欠阻尼二阶系统的阻尼比。

摘要： This application of a law in physics discloses relatively uncomplicated techniques for reducing the impact of auto collisions on our highways by providing aid to the motorist in slowing down his vehicle in time to avoid a hard collision, if such is to occur. The vehicle slows down from the blasts of high pressure air emitted from air valves in the auto's front end, producing a reaction of slowing down the vehicle. The blasts of air also aid in pushing the other vehicle out of the way so that the impact if any, would be less severe. The air valves in the auto's front end can be remotely swivable, servo driven, enabling the motorist to direct the air blasts in the direction of the menacing vehicle. The air blasts can be produced automatically from a simple calculation, providing the time in seconds for a collision to occur. If the time is less than a predetermined set value, then the air blasts are automatically turned on. In a similar manner, blasts of air at the auto's rear end can slow down the vehicle coming from behind to reduce the severity of the impact, if any. The high pressure of the blasts of air may last only a few seconds, enough time to produce the result of either reducing the impact of the collision or avoiding it altogether. A horn in the auto's rear also can warn and awaken the driver of the oncoming vehicle to slow down.
摘要翻译：物理法中的这种应用揭示了相对简单的技术，通过为驾驶者及时减速的方式减少自动碰撞对我们的高速公路的影响，以避免碰撞，如果发生这种情况，则会出现相对简单的技术。车辆从汽车前端的空气阀排放的高压空气的爆炸减慢，产生车辆减速的反应。空气爆炸也有助于将另一辆车推开，以便影响如果有的话，将不那么严重。汽车前端的空气阀可以进行远程可选，伺服驱动，使驾驶者能够沿着威胁的方向引导气流。气泡可以通过简单的计算自动生成，提供碰撞发生的时间（以秒为单位）。如果时间小于预定设定值，则气泡自动开启。以类似的方式，汽车后端的空气爆炸可以减缓从后方的车辆，以减轻撞击的严重性（如果有的话）。空气爆炸的高压可能持续只有几秒钟，足够的时间产生减少碰撞的影响或完全避免的结果。汽车后部的喇叭也可以警告并唤醒迎面而来的车辆的驾驶员放慢速度。

摘要： This apparatus is a tongs-like device for remotely scooping up cargo and personnel, comprising two identical elongated members pivoted at a selected distance from the device's top with a pivot pin. The lower portions are curved and vertical with cushions attached to their inner surfaces to enable the apparatus to hold either cargo or a person securely in place. Each inner lower surface has an inflatable pillow with a perforated spongy cushion attached to it and removable for replacement. The cushions' perforations enable a snatched person to breathe easily, thus avoiding any possibility of suffocation, while being hoisted upwards by hoist equipment. A sturdy net is fastened to the shoulders of the lower portions and draped for the person to sit on. In another technique a pliable plastic sheet, having pie-shaped triangular cuts, allows a person to pass through in one direction but not in the reverse direction.

摘要： This improved cable-scooping hook device with upper and lower portions and with a pivot pin and hubs is better able to snatch and scoop up a load cable than previous designs. Its tongs-like configuration can have a combination of magnetic hammerheads, weights on top and an extension spring to help force its lower portions, including jaws, to separate, when suspended cargo makes a touchdown onto a platform. To ensure that the load cable is snatched, a bar magnet is suspended from one or both hubs of the pivot pin. A ferrous metal load cable is attracted by the suspended magnet and held in place until the device's jaws close, as a load is lifted by the hoist cables. A person holding a long pole with a hook on its end guides the device to the load cable's location. When the hook reaches the load cable, attached to a load, the device is lowered to make contact with it, whereupon the cable is quickly snatched and scooped up, aided by the magnet's attraction. Another technique is described and illustrated for aiding a nonmagnetic cable to be snatched and scooped up.

摘要： This is a cable-scooping cargo hook device, pivoted near its center and weighted on top to help force its lower portions to automatically separate upon touchdown on a platform to discharge its load cable. By having the device sit on one of its jaws, the device can be made to avoid rescooping a discharged cable, in its simplest version. Also to assist in discharging its load cable are two inwardly protruding extensions with hammerheads, located above the pivot pin. These hammerheads have magnets of like polarity facing each other to produce a repulsive force and cause the device's jaws to open immediately when the hoist cables slacken, a feature to assist in the jaws straddling and scooping up a load cable. Also an electromagnet to perform the same function as the permanent magnets is described. Then a technique involving additional electromagnets enables the device not only to discharge a loaded cable while suspended, but also to improve its automatic loading ability. In addition to the use of one or more electromagnets for achieving positive load retention, positive load retention techniques are shown which are completely mechanical, requiring no electrical energy source.

摘要： This tongslike device for automatically loading and unloading materials, such as dirt or soil, sand, gravel, vegetables, fruit and leaves and even containerized loads, comprises two elongated members, pivoted approximately midway with a pivot pin. The lower portions of the device are flared to enable it to hold more material or larger size containerized loads. Its weight distribution between its upper and lower portions is such that its lower portions will separate automatically at touch down. The ends of its lower portions or jaws may be serrated and sharpened to enable it to dig into the ground or other material for loading. In one version, the device is capable of scooping up a load cable automatically because of the shape of its jaws. The size and shape of its lower portions determine the material or size and shape of the load capable of being scooped up. Such automatic loading and unloading devices would make the cargo loading and unloading operations safer and speedier under hazardous environmental conditions.

摘要： A hoist cable coupling device comprising a lower scissor-like part and an upper doughnut-shaped part, in which blades of the scissor-like part extend through the ring part and are locked in place when suspending a load. Hoist cables are attached to its upper part and load cables to its lower part. When the locking mechanism is of the magnetic type, it is so designed and so placed in a recess portion of the scissorlike part that it can be removed by personnel with ease whenever so desired. When the locking mechanism is of the solenoid type, it is an integral part of the scissor-like part with its plunger projecting into the same recess as above, when suspending cargo. The plunger is shaped to retract or rotate easily whenever required to unload cargo. In either locking technique, positive load-cable retension is acquired. The device cannot become unlocked by itself and be decoupled without action on the part of personnel.

摘要： For electronic experimental breadboards, connections can be made quickly, inexpensively using magnetic connectors. One way to accomplish this is by using hook-up wires with horseshoe- or U-shaped magnets at one or both of its ends. A U-shaped magnet can be inserted onto a cylindrical terminal post and also can be removed quickly with little effort. The magnet would hang on to a ferrous post by magnetic attraction. If the magnet should be of ceramic material and non-conductive, then the magnet would be coated with a conductive paint. To avoid magnets from sticking together, spacers are used, either by attaching plastic wafers or rings to the post or by providing grooves of the proper width in the post itself to receive the magnet. If spring terminals are used, instead of cylindrical posts, then the magnets are disc-shaped and placed on top of a terminal. A projected cylindrical portion at the bottom of each magnet drops into the terminal's central hole to keep the magnet in position centrally. A cavity is provided on top of each magnet to enable another such magnet to be placed centrally on top. A plastic ring is adhered, by cementing, to the top of each magnet to keep them apart and permit easier removal. Hence, a user has the choice either of inserting hook-up wire ends between coils of a spring terminal or of connecting one terminal to another using a disc-shaped magnet.Two or more independent terminals, side by side, can be patched almost simultaneously by using a plastic sleeve to envelop and hold together two or more magnets. Hence, two U-shaped magnets, held together by a plastic sleeve, can be applied to two posts. They also can be removed from two posts almost simultaneously. The method of patching suggested here encourages creative experimenting on the part of the student and researcher.
摘要翻译：对于电子实验面包板，可以使用磁性连接器快速，廉价地进行连接。实现此目的的一种方法是在其一端或两端使用带有马蹄形或U形磁体的连接线。 U型磁体可以插入到圆柱形端子柱上，也可以很少的努力快速移除。磁铁将通过磁吸引力挂在黑色金属柱上。如果磁体应该是陶瓷材料而不是导电的，那么磁体将涂上导电漆。为了避免磁铁粘在一起，可以通过将塑料晶片或环连接到柱上或通过在柱本身中提供适当宽度的凹槽来接收磁体来使用间隔件。如果使用弹簧端子，则代替圆柱体，磁体是圆盘形的并且放置在终端的顶部。每个磁体底部的突出的圆柱形部分落入端子的中心孔，以将磁体保持在中心位置。在每个磁体的顶部设置空腔，以使另一个这样的磁体能够集中放置在顶部。塑料环通过胶结粘附到每个磁体的顶部，以使它们分开并允许更容易的去除。因此，用户可以选择在弹簧端子的线圈之间插入连接线端子或者使用盘形磁体将一个端子连接到另一个端子。可以通过使用塑料套筒几乎同时地修补两个或更多个独立的端子，以将两个或更多个磁体包围并保持在一起。因此，通过塑料套保持在一起的两个U形磁体可以应用于两个柱。他们也可以几乎同时从两个职位上删除。这里提出的修补方法鼓励学生和研究人员进行创意实验。

摘要： A compact, self-contained, light-weight, easily programmable, desk-top analog computer, capable of being perpetually updated as new components and improved circuits are available. Unlike other such computers, the program panel is a combination patching, switching and electronic module board and includes all of the coefficient-setting potentiometers, voltmeters, function and mode control switches, and spare terminal strips for additional passive and active analog and digital logic circuits. Because of its small size and low cost, it could be more readily used as an aid to motivate high school and college students to study high mathematics, physics, electronics and automatic control systems. Unlike the pocket-sized digital computers, this computer provides both transient and steady-state solutions to differential equations which can be observed on an oscilloscope or graphically plotted on an x-y recorder receiving signals from computer modules. The reduction in size and weight is accomplished with the aid of integrated linear and nonlinear circuits and other subminiature components. Thus, the analog computing circuits for integrating, summing, differentiation, limiting, multiplication and division are simplified. Simplification in programming a differential equation and/or implementation by direct simulation from a functional block diagram is accomplished through a novel arrangement of parts, components, switches, jacks and diagrams to enable even the beginner to make interconnections rapidly and without the confusion sometimes associated with other analog and hybrid computers. Amplifiers may be zeroed for null voltage offset as on other analog computers. The mode controls include reset, hold, and compute as on other analog computers. Opportunity exists for introducing passive compensation or filter circuits for enhancing the stability of a control system more quickly and without tying up any operational amplifiers. This is not easily done on other analog computers. To further expedite implementing a problem on the computer panel, the user has a choice between using patch cords, toggle switches or a combination of the two, a feature not found on other analog computers. A feature worthy of merit is that none of the components need be soldered. Therefore, each is easily replaceable by others. In addition, the final preferred embodiment has been so designed that even a blind person can program a problem easily by feel. Because of the combination of visual and audio sound effects, solutions to differential equations will have added meaning to the student in mathematics, electronics and physics, contributing to his retention of objectives and purposes of the study.
