Inventor: PRICE ROBERT B
IPC: F01L13/06
Filed: 1991-03-14
Abstract: A process and apparatus are provided to maximize the retarding horsepower of a compression release engine retarder driven from the intake or exhaust valve pushtubes or the fuel injector pushtubes throughout the operating speed range of the engine without exceeding the maximum allowable loading of the pushtubes. The apparatus includes a timing advance mechanism incorporated into each slave piston (90) comprising a biasing means (102) responsive to the hydraulic pressure above the slave piston (90) which determines the position of a moveable stop means (96) whereby the timing advance of the slave piston is continuously varied in response to the hydraulic pressure above the slave piston (90). The process includes the steps of reducing the flow of fuel to the cylinder, increasing the hydraulic pressure above the slave piston (90) compressing a biasing means (102) in response to the hydraulic pressure above the slave piston (90), and moving a stop means (96) relative to the slave piston (90) in response to the compression of the biasing means (102) thereby continuously varying the timing advance of the slave piston.

Abstract: A gripper finger for a gripper spindle in a sheet-fed printing press includes first and second components. The first component has a gripper finger extension which contacts a gripper finger support at a transfer point. The first and second components cooperate to form an enclosure angle for enclosing the gripper spindle, with the first component contributing a maximum of 180 degrees to the enclosure angle and the second component supplementing the enclosure angle. The second component is fastened to the gripper spindle. A first compression spring is disposed between the ends of the first and second for exerting an adjustable, first spring force approximately in a direction of the transfer point. An adjustment screw is threadably engaged with one of the components and has a tip which lies against the supporting plane of the other component for exerting a screw force approximately in a direction of the transfer point. The first spring force and the screw force combine to form a resultant force in the direction of a line connecting the center point of the gripper spindle and the transfer point. A second compression spring clamped between the first component and the gripper spindle urges the first component against the gripper finger with a force greater than the first spring force and in a direction which essentially coincides with the direction of the resultant force.

Abstract: Disclosed is a method and apparatus for identifying remote terminals (12-14) which are networked in a digital loop transmission system. A Site Interface Unit (SIU) (15) at one of the remote terminals acts as a master. The Bank Controller Unit (BCU) (16) at each remote terminal calculates a 16-bit number based on its 60-byte serial number. A binary search is then performed by the SIU to determine the calculated number of each BCU, and an address is assigned to each remote terminal by the SIU. Any conflicts in the numbers initially calculated are resolved by transmission of the full 60-byte serial number.

Date Jun. 11, 1992.To increase the horizontal bandwith of the Weston PAL chrominance signal spectrum folding techniques are used. Spectral components with high horizontal frequency and low vertical and/or temporal frequency are carried as components with low horizontal frequency and high vertical and/or temporal frequency. A matrix (120) forms U+V(P) and U-V(M) chrominance signals which are then prefiltered using either rhombic spatial filters or rhombic vertical-temporal filters (122, 124). The two signals are then sampled by sampler (126, 128) which together with switch (136) form U+V samples on alternate lines to the U-V samples. The sampling patterns for the P and M signals are identical but shifted.
