  • Patent number: 4169390
    Abstract: A pressure control assembly having a snap-acting Belleville washer responsive to fluid pressure, and a switch actuating mechanism movable therewith, includes an adjusting mechanism for the snap-acting Belleville washer. The adjusting mechanism includes at least one pin which can be moved along the surface of the Belleville washer to change the Belleville washer's pivot point by increasing or decreasing its lever arm, thus varying its snap pressure. In the preferred embodiment, there are three pins which extend through aligned slots in an upper and lower plate and the pins can be moved radially inwardly and outwardly by rotating the lower plate relative to the upper plate.

  • Patent number: 4146184
    Abstract: A shredder for reducing scrap materials such as scrapped automobiles to pieces of a smaller size includes a shredder housing having an inlet and an outlet, rotary hammer means positioned in said housing, cutter means, and means for rotating said hammer means to co-act with said cutter means to reduce the material to smaller pieces. The outlet is closed by a door which contains a discharge grate through which shredded pieces must pass to leave the housing. The door is normally locked, but can be opened from the outside to permit unshreddables to be readily removed from the shredder and to replace the grate when necessary. In one embodiment the outlet is located in the end wall of said housing preferably about from the inlet and the door contains a grate which is comprised of a plurality of grate segments.

  • Patent number: 4131132
    Abstract: A mounting bracket assembly for releasably attaching a hose supporting boom to an overhead swivel cartridge of a car washing apparatus comprises a hinge plate adapted to be attached at one end to the rotatable outlet of the swivel cartridge, a boom body member from which the boom arm extends which body member has a hinge plate-receiving recess, compression means maintaining the hinge plate in the hinge plate recess of the boom body member and a jack which can be moved from an inoperative position to an operative position in which it is effective to maintain the compression means in a compressed state so that the boom assembly can be quickly detached from the hinge plate and the swivel cartridge can be replaced.

  • Patent number: 4131865
    Abstract: An electromagnet having a stationary core and a movable armature, each having three pole faces, forms a magnetic circuit having three substantially parallel legs when the core and the armature are brought together. The center leg of the magnetic circuit includes a demagnetizing airgap combined with a non-magnetic coating on a center pole face, which coating is more resistant to wear than the material of the uncoated pole faces.

  • Patent number: 4111176
    Abstract: A carburetor having a venturi constriction within an air passage leading to the engine intake manifold, a fuel bowl with a discharge nozzle for delivering fuel to the venturi constriction, and a bowl vent passage between the fuel bowl and a position at atmospheric pressure, includes a duct communicating between the venturi constriction and the fuel bowl. A solenoid valve is disposed in the bowl vent passage and is operatively connected to the ignition; the valve is open when the ignition is turned on so that the fuel bowl is exposed to atmospheric pressure allowing the nozzle to discharge fuel into the venturi constriction, and it is closed when the ignition is turned off. With the valve closed, the pressures in the venturi constriction and the fuel bowl are equalized preventing the flow of fuel through the nozzle to the venturi constriction and inhibiting "dieseling" after ignition shut-off.

  • Patent number: 4109895
    Abstract: A remote actuated metering valve system for supplying water to a washing fixture includes a main metering valve and at least one remote actuating relief valve connected to the main valve by tubing. The main metering valve has an inlet and an outlet with a valve seat between them and a movable piston which when the valve is in the normal closed position has its front face seated on the valve seat and its elongated nose projecting through the valve seat. The piston is maintained in the closed position by supply line pressure which is transferred via a bypass timing circuit to a pressure chamber behind the piston where it is sensed by the rear face of the piston. The pressure chamber of the main valve is connected by tubing to a normally closed remote push button relief valve. A second length of tubing leads from the relief valve to the supply source at a point downstream of the valve seat.

  • Patent number: 4101031
    Abstract: A package for a prosthetic heart valve or the like comprising a pair of separable mating package sections for receiving the heart valve and retaining it in sterile manner in biased position against a resilient pad. A separate retainer member is positioned in the package for biasing the heart valve against the pad, the retainer member being a rigid sheet having an aperture adapted to receive a portion of the valve. One of the mating package sections is provided with a shoulder which urges the retainer member into a biased position against the heart valve so that the valve is in turn biased against the resilient pad. The shoulder is adapted to slide along the surface of the retainer member so that the torque is not transmitted to the heart valve when the package sections are rotated to open or close the package.

  • Patent number: 4088302
    Abstract: A seal member for a noncompression-type faucet valve comprises a cylindrical member having an open top and an open bottom, both of which are partially closed by inwardly directing flanges. The member is further provided intermediate its length with an external outwardly directed circumferential ridge. The seal member is intended for use in a faucet valve which has a rotatable valve stem having an inlet passage offset from the axis of rotation positioned within the bore of a valve housing that has an inlet port which is offset from the axis of the bore. Flow through an outlet tube leading from the bore is controlled by rotating the stem to move the inlet passage into and out of registry with the inlet port in the bore.The seal member is comprised of a resilient material such as butane rubber and it is friction fit into a seal-receiving recess about the inlet port in the bottom of the valve housing.

  • Patent number: 4088297
    Abstract: A timed metering valve includes a valve body having an inlet and an outlet which are connected by a passageway surrounded by a valve seat at its upper periphery; a cylinder; a movable piston having a front face and a rear face positioned in said cylinder, the front face of said piston normally being seated upon the valve seat preventing the flow of fluid through said passageway; a bypass circuit leading from the inlet through a timing mechanism to a pressure chamber behind the rear face of the piston so that supply line pressure sensed by the rear face of the piston maintains the valve in the closed position; and relief valve means for relieving the pressure in said pressure chamber so that the supply line pressure can move the front face of the piston off its seat to open the valve.

  • Patent number: 4077602
    Abstract: An actuating valve serves as a pilot to a control valve for a valve controlled flushing system for a tank-type toilet installation which comprises a siphon flush valve, and a control valve that allows supply water to flow into the tank to initiate siphonic action, to supplement flow through the siphon flush valve and to refill the tank, which control valve utilizes a piston which is ordinarily seated in a closed position by supply line pressure. The actuating valve is located in a bypass passage between the supply pressure and a timing pressure chamber of a control valve.
