摘要： This invention is an improvement over the arrangement and couplings between the piston rod and output power shaft in an internal combustion engine.The piston rod's reciprocating movement is substantially linear along the center line of the rod and piston assisted by a guide slidably coupled to the rod. The rod has a set of gear teeth along its side forming a rack gear.The output power shaft has at least one sector gear keyed or otherwise affixed thereto. The sector gear engages the gear teeth on the rod only during one direction of the rod's reciprocating movement which is the same direction as the power stroke. The sector gear is disengaged from the rod at the end of the piston's power stroke and remains disengaged, while continuing to rotate, until the beginning of the next stroke with the same direction as the power stroke. When the sector gear is disengaged, the piston and rod are returned to the beginning of the piston's power stroke by an oscillating sector gear which engages a second set of gear teeth on the rod. Timing gears synchronize the moving parts.A plurality of sector gears, pistons and rods are shown in a second preferred embodiment which permits omitting separate timing gears and oscillating gears.The invention is a cooler running engine which delivers higher torque than a comparable conventional engine while conserving fuel. A longer piston stroke is allowed which reduces pollution emissions.
摘要翻译：本发明是对内燃机中的活塞杆和输出动力轴之间的布置和联接的改进。活塞杆的往复运动沿着杆的中心线基本上是线性的，并且活塞由可滑动地联接到杆的引导件辅助。该杆沿其一侧具有一组齿轮齿，形成齿条。输出动力轴具有至少一个扇形齿轮，或者以其他方式固定到其上。扇形齿轮仅在杆的往复运动的一个方向上与杆上的齿轮啮合，该方向与动力行程相同。扇形齿轮在活塞动力行程结束时与杆脱离，并保持分离，同时继续旋转，直到下一次行程的开始与动力行程相同的方向。当扇形齿轮脱离时，活塞和杆通过与杆上的第二组齿轮齿接合的摆动扇形齿轮返回到活塞动力行程的开始处。定时齿轮同步移动部件。在第二优选实施例中示出了多个扇形齿轮，活塞和杆，其允许省略单独的定时齿轮和摆动齿轮。本发明是一种冷却器运行的发动机，其在节省燃料的同时传递比相当的传统发动机更高的扭矩。允许更长的活塞冲程，减少污染排放。

摘要： The continuously variable transmission has a rotating drive unit and driven unit sharing a common axis. Splined drive shafts extend radially from the common axis and are rotatably driven by the drive unit. Drive rollers are splined to the drive shafts so that the drive rollers are shiftable along the length of the drive shafts. The drive rollers transmit power directly to the driven unit in forward drive. The shift of the rollers while in forward drive continuously varies the distance between the rollers and the common axis so that the shift continuously varies the torque drive to the driven unit. All the drive rollers in a plurality are always equidistant from the common axis. Elastohydrodynamic oil may be used between the rollers and the driven unit to prevent metal to metal contact.Neutralizing the drive can be done by shifting the drive rollers a certain distance from the common axis at which distance the rollers are disengaged from the driven unit. For reversing the drive, continued radial shift brings the rollers into contact with second rollers. The second rollers transmit the power from the drive rollers to the driven unit which causes the driven unit to reverse its direction of rotation.
摘要翻译：无级变速器具有旋转驱动单元和共用公共轴的从动单元。花键驱动轴从公共轴线径向延伸并由驱动单元旋转驱动。驱动辊与驱动轴花键接合，使得驱动辊可以沿驱动轴的长度移动。驱动辊在正向传动中直接传动到被驱动单元。在正向驱动的同时，辊的移动连续地改变辊和公共轴之间的距离，使得变速连续地改变到被驱动单元的转矩驱动。多个的所有驱动辊总是与公共轴线等距离。可以在辊和从动单元之间使用弹性流体动力学油以防止金属与金属接触。驱动器的中和可以通过将驱动辊与公共轴移动一定距离来完成，在该距离处辊子与被驱动单元脱离距离。为了反转驱动器，持续的径向位移使滚子与第二个滚轮接触。第二辊将动力从驱动辊传递到从动单元，从而使从动单元反转其旋转方向。

摘要： The conventional crank between the power piston and the crank shaft in a reciprocating engine is replaced by a fixed length moment arm during the power stroke and a scotch yoke during the return stroke.The motion of a power piston is converted to rotary motion at an output power shaft through the fixed length moment arm. The moment arm is the radius of a sector gear which is non-rotatably secured to the output shaft. The piston rod is modified to include a rack gear and a slot. The slot and the output shaft form the scotch yoke.The sector gear engages the rack only during the down stroke of the piston. The sector gear disengages just before the down stroke is completed. The piston is then timely returned to the precise position of its next stroke through the scotch yoke.The fixed length moment arm acts as a lever through the entire stroke of the pistion which reduces combustion pressure and temperature. The reduced combustion pressure permits a smaller combustion charge which saves fuel. The reduced pressure and combustion reduce exhaust pollutants. The stroke can be longer than the conventional crank, thereby applying the power through a greater angular displacement of the power shaft.Instant torque is achieved through the moment arm.The invention can be either the two or four stroke type.
摘要翻译：往复式发动机中的动力活塞和曲轴之间的常规曲柄在动力行程期间由固定长度的力矩臂替代，并且在返回行程期间被替换为苏格兰杆。动力活塞的运动通过固定长度力矩臂在输出动力轴转换为旋转运动。力臂是不可旋转地固定到输出轴的扇形齿轮的半径。活塞杆被修改为包括齿条和槽。槽和输出轴形成苏格兰杆。扇形齿轮仅在活塞的下冲行程期间啮合齿条。在下降行程完成之前，扇形齿轮脱离接合。然后将活塞及时返回到其下一次行程的精确位置，通过苏格兰转盘。固定长度力矩臂通过活塞的整个行程作为杠杆，这降低了燃烧压力和温度。降低的燃烧压力允许较小的燃烧装料，从而节省燃料。减压和燃烧减少排气污染物。行程可以比常规曲柄更长，从而通过动力轴的更大的角位移施加动力。瞬间扭矩通过力臂实现。本发明可以是二冲程或四冲程型。

摘要： This invention uses magnetic levitation in combination with magnetic propulsion (MAGLEV) to accelerate an aircraft of spacecraft--or both crafts as a coupled unit--from standstill along a guideway to the highest possible launch velocity. The acceleration along the guideway is fuel efficient. The craft(s) are brought to launch velocity without using on board fuel. The computer controlled acceleration along the guideway could avoid high g forces to prevent damage to fragile payloads. The guideway may be sectionalized and of any shape. One section, for instance, may be circular to permit a long magnetically accelerated run with a relatively short length guideway. Very heavy crafts and payloads can be launched with superconducting levitation magnets in the guideway which form strong repulsive force fields with superconducting magnets in the MAGLEV vehicle. In another embodiment, the invention includes attraction magnets for the levitation. The invention could operate in an airless environment, such as the moon, to launch rocket powered spacecraft with their payloads. On earth, the invention could launch a rocket powered spacecraft coupled to an aircraft having air breathing engines. The aircraft would power the spacecraft to a staging altitude, where the spacecraft would actuate its own rocket engines for propulsion beyond the atmosphere, and separate from the aircraft. Unlike the space shuttle, all major components of the invention's space launch would be recovered for reuse. The invention may be multipurpose for serving to efficiently launch conventional aircraft. With a circular guideway, takeoff is inherently omnidirectional to take advantage of launch conditions.

摘要： This invention is an improved modular engine having replaceable power modules wherein the improvement consists of automatically coupling and decoupling the power modules and the engine's power output shaft in response to immediate operating requirements resulting in fuel savings. When a unit is decoupled, it is shut down and does not use fuel or add load to the engine. This feature saves fuel whenever operating requirements permit a reduction in power. The power units may be of several types known to the art. The power units are shown to have a gear which meshes with a gear part of the engine's power output shaft to drive the shaft. A microprocessor is shown to control the dynamic coupling and decoupling between the unit's gear and the power output shaft to keep the invention properly timed and fuel efficient. A flywheel is shown, in combination with the other parts, to store regenerated energy and release the energy to the power shaft upon demand. This feature of the invention provides an additional fuel savings.
