摘要： In a two-stroke opposed-piston engine, a ported cylinder with a pair of opposed pistons is equipped with a decompression port including a valve and a passage with an opening through the cylinder wall that is located between the cylinder's intake and exhaust ports. The decompression port enables release of compressed air from the cylinder after the intake and exhaust ports are closed. The valve is opened to permit compressed air to be released from the cylinder through the passage, and closed to retain compressed air in the cylinder. Engine braking is supported by release of compressed air through the decompression port into an exhaust channel when the pistons are at or near top dead center positions as the cycle transitions from the intake/compression stroke to the power/exhaust stroke. Compression release from the cylinder after intake and exhaust port closure can also support other engine operations.
摘要翻译：在二冲程相对活塞式发动机中，具有一对相对的活塞的移动式气缸配备有减压口，该减压口包括阀和具有位于气缸的进气口和排气口之间的通过气缸壁的开口的通道。减压口能够在进气口和排气口关闭后释放压缩空气。阀被打开以允许压缩空气通过通道从气缸释放，并且关闭以将压缩空气保持在气缸中。当循环从进气/压缩冲程转换到动力/排气冲程时，当活塞处于或接近上死点位置时，将压缩空气通过减压口释放到排气通道中来支持发动机制动。进气和排气口关闭后气缸的压缩释放也可以支持其他发动机的运行。

Lubricant is wiped from the piston as the piston travels into the bore toward its top dead center position.

摘要： A piston rolling thrust bearing construction is constituted of a pair of bearing plates with opposing faces disposed in a spaced alignment with a rolling ball assembly positioned between the opposing faces to support relative movement between the bearing plates. The piston rolling thrust bearing is mounted to the open end of the skirt of a piston disposed in a cylinder to compensate for non-axial motion relative to the cylinder axis due to the articulating motions of connecting elements or any structural misalignments within an engine drive train assembly.

摘要： A two-cycle, opposed piston engine with side-mounted crankshafts and cylinders isolated from mechanical stresses of the engine includes tailored cooling of cylinders and symmetrical cooling of the interior surfaces of piston crowns. Each opposed piston includes a compliant member that permits movement of an axially-centered rod mounted in the piston in order to maintain axial alignment with the bore of a cylinder in which the piston is disposed during engine operation. A single wristpin is disposed externally of the piston to connect the piston with connecting rods that run between the piston and the crankshafts.

摘要： A flying head slider is flown above a rigid rotating magnetic disk at such a height that it is both aerodynamically stable and immune to collisions with disk asperities. A position adjustable magnetic transducer is mounted on the slider and is controllably lowered to an operating position very close to the disk where its position is maintained by a servo system. An anticipator probe detects the presence of asperities on the disk in the path traversed by the transducer, and generates a control signal which causes the transducer to be retracted to a safe height.

摘要： A pair of field store devices which are slaved to a stable sync signal are employed to record, along with such sync signal, video information on a recording medium. During periods of asynchronism in the video input to the field store devices, synchronous noise or a synchronous blank is inserted into the output of the field store devices. Such use of field store devices enables (1) the easy conversion of one recording format to another; (2) the splicing of scenes recorded on different tapes of the same, or different formats to be effected on a tape with any format; and (3) the recording of stillframe scene information.
