摘要： A gimbaled load pad mounting arrangement in which a rigid load pad is detachably mounted on the spherical end of a spring-loaded mounting shaft. The load pad is provided on the side with flexible retention hooks with finger portions that engage the underside of the mounting frame to hold the load pad in position during assembly. Once the magnetic head is mounted in position, the pressure of the head against the load pad disengages the finger portions from contact with the underside of the frame thereby allowing the gimbaled load pad to assume its exact constraint position against the face of the magnetic head.

摘要： A dual speed film drive apparatus to achieve high speed and low speed film drive employs a limited speed range stepper motor with pinion input drive gear, and an output driven gear connected to a film advance mechanism. High and low speed drive is achieved by use of a pivoted intermediate gear drive module having high speed and low speed gear set positions to interconnect the stepper motor input drive gear to the output driven gear. Shifting of the gear module between gear set positions is accomplished by a DC motor operated cam drive mechanism which pivots the gear module selectively between the high speed and low speed gear set positions. The cam drive mechanism includes a camming slot having dwell segments at each end of the slot. An open loop control gear mesh procedure includes is also described for meshing the high speed and low speed intermediate gear drives with the input drive gear and output driven gear. In this procedure, the cam drive mechanism initially drives the gears toward mesh and then reverses the cam drive by a limited amount. If the input drive gear properly meshed with the intermediate gear drive, the dwell segment prevents the gear from being unmeshed. If stubbing occurred, the cam drive is still in the drive segment of the cam and backs the intermediate gear drive away while the stepper is activated by a partial tooth pitch. The cam drive is then driven forward again to engage the intermediate gear with the input gear. The stepper motor is then driven forward and back by equal amounts to clear any stub condition that might still exist between the intermediate gear and output driven gear interface. The open loop control routine avoids the need for complex and costly active feedback mechanisms to detect and clear a gear stubbing condition during gear shifting.
摘要翻译：用于实现高速和低速薄膜驱动的双速胶片驱动装置采用具有小齿轮输入驱动齿轮的限速步进步进电机和连接到胶片推进机构的输出从动齿轮。通过使用具有高速和低速齿轮组位置的枢转中间齿轮驱动模块来实现高速和低速驱动，以将步进马达输入驱动齿轮与输出从动齿轮相互连接。齿轮模块在齿轮设置位置之间的转换由直流电动机操作的凸轮驱动机构实现，该凸轮驱动机构在高速和低速齿轮组位置之间有选择地枢转齿轮模块。凸轮驱动机构包括在槽的每一端具有驻留段的凸轮槽。还描述了一种用于将高速和低速中间齿轮传动与输入驱动齿轮和输出从动齿轮啮合的开环控制齿轮啮合程序。在该过程中，凸轮驱动机构首先将齿轮驱动向网状物，然后使凸轮驱动器反转有限的量。如果输入驱动齿轮与中间齿轮传动装置正确啮合，则停留段可防止齿轮脱离啮合。如果发生短路，则凸轮驱动器仍然位于凸轮的驱动部分中，并且在步进器被部分齿距激活的同时将中间齿轮传动器背离。然后再次向前驱动凸轮驱动器，以将中间齿轮与输入齿轮接合。然后，步进电机向前和向后驱动相等量，以清除中间齿轮和输出从动齿轮接口之间可能仍然存在的任何残留条件。开环控制程序避免了在变速期间需要复杂和昂贵的主动反馈机制来检测和清除齿轮桩的状况。

摘要： A compact developing apparatus that can quickly modify processing chemistries is disclosed. A web coated with a photograph emulsion or other photosensitive material forms one wall of a processing chamber and processing chemicals are introduced sequentially into the stationary chamber. The heating of the processing chemicals to their required temperatures is accomplished by applying microwave energy to the chemicals upstream of the chamber. The heating is controlled by a programmed digital computer to provide forward and backward feedback control of the microwave output in response to temperature and flow rate measurements.

摘要： A liquids mixing and dispensing apparatus and method utilize a plurality of liquid supply modules to feed simultaneously charges of a plurality of admixable liquids at predetermined volume flow rates to a mixer to form a batch of a mixture of the liquids, such as a photographic emulsion mixture, in which the liquids are in a predetermined volume ratio. As it is formed, the mixture is delivered to a storage conduit connected to a dispenser, for later dispensing of a discrete volume thereof as a coating onto a moving web by feeding a purge liquid to the mixer. Each module has a piston and cylinder unit with an inlet and outlet (a cylinder port conduit) connected to one end of a tube having a volume at least as large as the maximum volume of the cylinder swept by its piston when driven by an associated motor. A valve selectively connects the other end of the tube either to a liquid source or to the mixer. The ratio of the intermediate or maximum volumes swept by the pistons when concordantly driven by their motors is selected to provide the desired volume ratio of the liquids in the mixture.

摘要： Film scanning apparatus having a film cartridge chamber for receiving a film cartridge containing photographic film having images to be scanned, a film takeup chamber and a film scan gate therebetween. The apparatus has an upstream nip roller set positioned between the film cartridge chamber and the film scan gate and includes at least one drive roller and pinch roller set in which the drive roller has a compliant film engagement surface. A downstream nip roller set is positioned between the film scan gate and the film takeup chamber and includes at least one drive roller and pinch roller set in which the drive roller has a compliant film engagement surface. The upstream nip roller set exerts constant tensioning force on film in the film scan gate buffering the film in the film scan gate against variable tensioning effects on the film caused by the film cartridge. A drive motor is directly connected to the downstream drive roller set and the downstream roller set is drivingly connected to the upstream drive roller set by an elastic drive belt. A differential compression force is exerted on the pinch rollers such that the force on the downstream pinch rollers is greater than on the upstream pinch rollers thereby causing a film speed differential between the upstream and downstream roller sets that maintains a desired degree of tension on film transported through the film scan gate.
