  • Patent number: 4343153
    Abstract: Means are disclosed for dissipating supercharge pressure in a hydraulic system including a reversible pump (18) directly connected to a hydraulic cylinder (22). Supercharge pressure results from unequal areas on either side of a piston (24) of a single-ended hydraulic cylinder (22). When the piston moves towards the blind end of the cylinder (22), more fluid is displaced from the cylinder than is admitted to the cylinder on the opposite side of the piston. Means responsive to a pressure at a first port (82) of the pump (18) opens a passage between the second port (76) of the pump (18) and a fluid reservoir (16), allowing fluid in excess of the pump's intake requirements to pass to the reservoir (16). In a first embodiment of the invention, a rocker mechanism (60) is actuated by a piston (66) responsive to pressure at the first port (82) pressing against a first end (20) of the rocker mechanism (60), the second end (74) of the rocker mechanism (60) displacing a check ball (38) of a keep-full valve.

  • Patent number: 4343155
    Abstract: A hydraulic circuit (10) has a fluid supply source (12) to a work element, such as a control valve (14) for a work implement, connected by a first fluid pathway (18). A second work element (16), such as a master cylinder reservoir of a brake system, has a fluid level (36) which is desirably maintained against leakage in the system to prevent problems in using the brake system. The master cylinder reservoir (16) is associated with the hydraulic circuit (10) by apparatus (38,42) which initiate pressure conditions in fluid pathways (22,24) positioned in fluid communication with the master cylinder reservoir (16) to maintain the desired fluid level. The pressure conditions create a pressure differential which initiates or induces a fluid flow from the hydraulic circuit (10) to the master cylinder reservoir (16) to maintain the reservoir fluid level and substantially prevent undesirable braking characteristics which can result from an improper fluid level.

  • Patent number: 4343175
    Abstract: A power press in which low inertia motors with speed control circuitry are connected to a cam which acts upon a lever or cam follower which, in turn, cooperates with a force-storing element which has a spring action and is coupled, e.g. by the same lever, to the tool of the press. Accordingly, in the rotation of the cam, the force-storing means stores potential energy which is transformed into kinetic energy of the ram in another region of the cam at which part of the energy can be delivered to the low inertia motors. Hence the speed control of the motor will, in part, regulate the rate at which the stored force is delivered to the workpiece.

  • Patent number: 4343180
    Abstract: The interior of a differential pressure cell is exposed to the pressure in the intake pipe of an internal combustion engine. An absolute pressure cell is exposed to the ambient air pressure. The movable membrane of the differential pressure cell carries a plate on which are mounted two permanent magnets whose North poles face one another. A Hall generator fastened to the center of the movable membrane of the absolute pressure cell moves in the gap between the two magnets. The effective magnetic field applied to the Hall generator thus varies with the relative position of the Hall generator and the magnets. Adjustment of the spring constants of the two membranes allows any linear combination of differential and absolute pressure to be formed. Embodiments of different complexity and different degrees of linearity are illustrated.

  • Patent number: 4343182
    Abstract: In a radiation heat loss detector, radiation from an extended surface area is detected with a sensor having a wide field of view closely matching that of an associated camera. By simultaneously photographing the surface area of interest and detecting the radiation from that same area, a clear record is provided for future use. A wide band radiation sensor is used. Compensation for environmental radiation is made by first viewing the environment with the sensor and holding the sensed signal and then subtracting that signal from the flux detected when the sensor faces the extended surface area. The date and time are also recorded on the photograph. A sonar device positioned on the camera provides a distance indication which, with a known field of view, allows for a determination of the total flux from the surface area, a determination of convective heat losses from the surface and a correction for atmospheric absorption of the radiant energy.

  • Patent number: 4343191
    Abstract: This invention is a fluid flow meter with pulse output proportional to the fluid flow rate. The pulse is tranduced by means of a pick-off sensor from the by-passing of a ball which travels in a toroidal passageway at speed close to that of the velocity of the fluid. The fluid flowing into the device follows a loop-shaped circular passageway while the ball travels in a closed circular passageway. Fluid flow propels the ball to revolve continually at a rate directly proportional to the flow rate of the fluid.
