Abstract: A pair of locating washers are applied over the holes in the bottom mounting lugs of the kinescope. The washers have apertures which are precisely referenced with respect to the position of the kinescope screen by using a pair of oppositely-disposed screen locating marks. The TV cabinet, on the other hand, is equipped with a pair of tapered guiding posts on the inside front surfaces thereof, which are similarly referenced relative to the rectangular opening of the cabinet. When the kinescope is loaded into the cabinet, the cabinet guiding posts are received into the kinescope-mounted locating washers to assure registration between the kinescope screen and the cabinet opening. The kinescope is fixedly secured to the cabinet by a plurality of screws.

Abstract: A method of operating a free piston engine of the present invention, includes a housing with a combustion cylinder and a second cylinder. A piston includes a piston head reciprocally disposed within the combustion cylinder, a second head reciprocally disposed within the second cylinder, and a plunger rod interconnecting the piston head with the second head. A supply of hydraulic fluid is pulsed from a high pressure hydraulic accumulator into a pressure chamber in the second cylinder adjacent the second head during a beginning portion of a compression stroke to cause the piston head to move toward a top dead center position. The high pressure hydraulic accumulator is decoupled from the pressure chamber after the pulsing step. A low pressure hydraulic accumulator is coupled with the pressure chamber during a remaining portion of the compression stroke. The high pressure hydraulic accumulator is coupled with the pressure chamber when the piston head is traveling toward a BDC position during a return stroke. A sensor senses a position of the piston which is at or near the BDC position and provides a corresponding signal. The coupling between the high pressure hydraulic accumulator and the pressure chamber is maintained for a period of time, dependent upon the sensor signal.

The movable member is movable along a path and has a surface with a plurality of markings provided thereon. The method includes sensing an image of a portion of the surface of the movable member, and calculating a position of the movable member based on the image. Further, the method includes determining whether the movable member is at a location corresponding to one of the plurality of markings, and eliminating an error associated with the position when the movable member is at the location corresponding to the one of the plurality of markings.

Abstract: A pressure transformer is provided having a housing, with a rotating group disposed therein, an adjustable port plate is disposed between a barrel of the rotating group and a head portion of the housing. The barrel has a plurality of pistons slideably disposed in cylinders defined in the barrel. The cylinders each define a cylinder port that is in intimate contact with the port plate. The port plate has three arcuate slots defined therein and spaced from one another along a predetermined circumference. Each arcuate slot has a leading edge and a trailing edge. Likewise each of the cylinder ports has a leading edge and a trailing edge. The shape and orientation of the leading edges and trailing edges of the cylinder ports and the arcuate slots are the same. During relative rotation between the cylinder ports and the arcuate slots, the leading edges of the cylinder ports and the leading edges of the arcuate slots are radially concurrent. Likewise, the trailing edges of the cylinder ports and the trailing edges of the arcuate slots are radially concurrent. This relationship enhances the operating efficiency of the pressure transformer.

The barrel has a plurality of pistons slideably disposed in cylinders defined in the barrel. The cylinders each define a cylinder port that is in intimate contact with the port plate. Each cylinder port has a predetermined circumferential length. The port plate has three arcuate slots defined therein and spaced from one another along a predetermined circumference. Each arcuate slot has a leading edge and a trailing edge. Likewise each of the cylinder ports has a leading edge and a trailing edge. The shape and orientation of the leading edges and trailing edges of the cylinder ports and the arcuate slots are the same. The circumferential length of the space between adjacent ones of the arcuate slots is less than the circumferential length of the respective cylinder ports. During relative rotation between the cylinder ports and the arcuate slots, the cylinder ports is in communication with the adjacent arcuate slots but during operation the communication is effectively dynamically sealed. This relationship enhances the operating efficiency of the pressure transformer by conditioning the fluid within the cylinder so that the pressure therein is equivalent to the pressure in the successive arcuate port upon opening thereto.
