Abstract: A VALVE ASSEMBLY HAVING A PREDETERMINED SHEAR LINE         ABSTRACT OF THE DISCLOSURE         A valve assembly is disposed between an accumulator and a pressure chamber in a hydraulic brake booster.  The valve assembly operates to communicate the pressurized fluid to the pressure chamber when the pressurized fluid within the pressure chamber is insuffici-ent to provide a power assist during braking.  The valve assembly comprises a base which is received within a housing separating the accumulator from the pressure chamber.  The base defines an opening leading to the housing bore and a body extends into the opening to define a clearance between the base and the body.  The clearance leads to a recess on one end of the body which cooperates with a recess on the other end of the body to define a shear line for the body,  The body is cut out on the one end of the body adjacent the recess to define a secondary passage and a portion of the body is movable after shearing into engagement with the base to substantially take up the clearance.  The cutout cooperates with the base to define a restriction for the secondary passage which communicates the accum-ulator with the pressure chamber.

Abstract: MOTION COMPENSATOR AND CONTROL SYSTEM FOR CRANE                           ABSTRACT     A motion compensation system for a crane hoist and control system therefor serve to assist the crane operator in safely lifting loads from the deck of a heaving work boat.  The crane hook is allowed to follow the motion of the load because a level of pretension is maintained on the line (wire rope) by means of a counterweight connected to a four-part reeving system in the line.  A hydraulic cylinder is connected to the counterweight to provide a means of locking movement of the counter-weight and also provides a cushion at both ends of the travel of the counterweight.  Movement of the piston in the cylinder is controlled by means of a control system including a conduit having a check valve allowing flow between the rod end and the opposite end of the cylinder which permits the reeving system to take up line.  This check valve may be bypassed by an operator-controlled switch to pay out line.  A damping circuit prevents too rapid movement of the piston in a downward direction.  A limit switch responds to movement of the piston and counterweight near the top of their travel to actuate a light to warn the operator of a need to pay out line.  As the piston and counterweight approach the bottom of their travel which indicates the load is moving upward, another limit switch actuates a light to indicate time to lift the load.  A relief valve is provided in parallel with the operator-controlled switch which responds to excessive load to reduce the pressure and permit more line to be paid out.  A separate pressure-responsive switch responds to normal working pressure in the rod end of the cylinder to override the input to the operator-controlled switch during operation of the crane to prevent line from being paid out even though the operator might inadvertently provide an input to the operator-controlled switch.

Abstract: ABSTRACT A color copier having high resolution projection optics is modified to include low resolution electrical correction method and apparatus.  A latent electrostatic image of an original is generated with conventional lamp and lens projection optics.  This optical latent image is corrected for tone or color in real time by a parallel raster exposure arrangement.  A raster input scanner (RIS) generates electrical raster image signals repre-sentative of the original.  A processor converts electri-cal correction signals according to a prescribed scheme from the raster image signals.  A raster output scanner (ROS) generates a raster latent image generated in regis-tration with the optical latent image in response to the electrical correction signals.  The RIS uses charge coupled devices (CCD's) to generate the electrical raster signals and the ROS uses a laser, and galyanometer to generate the raster latent image.

Abstract: ABSTRACT OF THE INVENTION     A protection circuit for multi-phase motors provides circuits for protecting a motor against low voltage, phase reversal or loss of a phase and other improper operating conditions on both the line side and the motor side of the main motor contactors.  The line and motor side circuits are interrelated such that an unsafe condition on either side of the contactors causes the contactors to be opened.  A time delay circuit on the motor side of the contactors pre-vents interruption of the holding circuit until conditions on the motor side of the contacts have been established and sensed for opera-tion, proper or otherwise, during motor start up.

Abstract: ABSTRACT In a data processing device using flexible magnetic disc media, ap-paratus is disclosed for improved positioning of a magnetic read/record head against the recording surface of a magnetic disc.  A carriage, moveable radial-ly on the disc, has two opposed swing arms pivotal between a load position and a retracted position.  A gimbal spring is cantilevered to each swing arm and carries at its free end a transducer.  A retainer is attached to the end of each swing arm.  During movement of the swing arm toward the load position, each retainer is engaged with its associated gimbal spring and maintains its associated head in a controlled attitude as the head approaches the disc.  In the load position, the heads are opposite one another against recording sur-faces on opposite sides of the disc, and each is free of its associated retain-er.  As the swing arms are moved from the load position toward the retracted position, each retainer engages its associated gimbal spring to pull the asso-ciated head from the disc surface in a controlled attitude.
