  • Patent number: 4252050
    Abstract: A control valve unit (10) disclosed supplies hydraulic fluid to an actuator (12) in a manner that controls both acceleration and deceleration of the actuator movement. A supply valve (14, 22) of the unit is movable from a central closed position in opposite directions to open positions and back to the closed position by a servomechanism (16) and a control circuit (18) that operates the servomechanism to cooperatively control the supply of the hydraulic fluid to the actuator in a manner which controls both acceleration and deceleration of the actuator movement. A control member (62) of the servomechanism operates the supply valve and is moved in a controlled manner by cooperative operation of a pair of hydraulically operated pilot pistons (88a, b), a pair of acceleration control pistons (90a, b), and a pair of deceleration cams (84a, b). Directional and flow control valves (89, 92) of the control circuit operate the pilot pistons and the acceleration control pistons in cooperation with each other.

  • Patent number: 4249705
    Abstract: Method and apparatus for dispensing unconfined flat coiled strips, mults of which have been stacked in coaxial alignment. The mults form an enlarged cluster coil and in some cases the mults are severably attached to one another. Strip dispensing is effected successively from one coil at a time by means of a turntable upon which the coiled mults are set and associated accessory gear, including supportive coactively mounted coiled snubber and clamping coils, gate and dancer rolls with associated speed control and a pay-out basket assembly, adapted to rotate the dispensed strip to a desired plane. The invention is characterized by eye to the sky dispensing of strips from coils which, aside from the stacking, are otherwise unconfined. In a refined form wherein mutliple mults are attached to one another, the strip is peeled from a given mult by a peeling-blade which is associated with the snubber roller.

  • Patent number: 4244687
    Abstract: A chain for use with kilns defines links, each with a flat area. The connection between the links is such that the flat areas in adjacent links tends to align with each other in the hanging attitude of the chain whereby the chain may be hung with the flat areas facing axial flow of materials in the kiln and acting as an impediment thereto. Arrays of such chains are hung from the wall of the kiln to collectively impede the flow of gas-borne particulate material.

  • Patent number: 4243858
    Abstract: A snap disc operator pressure switch is disclosed in which a thin flexible diaphragm is positioned adjacent to the disc to isolate the pressure chamber from the disc chamber and to transmit the pressure forces directly to the surface of the disc. The disc is positioned in a disc seat and is held therein by the diaphragm. The calibration of the disc is not adversely affected because it is not necessary to provide a seal directly with the disc. The disc seat member is shaped to support the disc against overpressure and to provide a guide for the switch bumper. When higher operating pressures are required, two discs are positioned in the disc seat at face-to-face adjacency and the device operates at a pressure substantially equal to the sum of the calibration pressures of the discs. In another embodiment, the movable arm of the switch is biased closed and is moved to an open position by a spring-biased operator.

  • Patent number: 4240584
    Abstract: An agricultural field unit taking the form of a vehicle for applying by spray means irrigation water or other fluids to crops. The unit is powered during its operational run by the same water supply that provides the irrigation water for spraying purposes. A winch and winch cable are employed to mark exactly the destination point for the vehicle during its water-powered run. The vehicle carries a hose reel the hose of which is alternately transported, attached to a water pressure source and spooled off the reel during a primary vehicle run, and then coupled to the fluid inlet of the vehicle and dragged thereby over the field during the intended sprinkling operation.

  • Patent number: 4238026
    Abstract: The specification discloses an accumulating conveyor system (10) including fixed support rails (24), a pair of chains (18), each having half tall links (70) and half short links (72), mounted around upper and lower movable guides (68) and (66) respectively. Air bags (52) serve to raise the guides and chains to lift stacks or cases off the rails, and a cylinder (96) serves to index the raised guides and chains forward, whereupon the air bags are deflated to set the stacks back onto the rails, and the cylinder retracts. When a stack is thus "walked" to the end of the tall links, a switch (104) causes the chains to retract the length of a stack plus a clearance gap relative to the guides (68) to accommodate the accumulation of the next stack and bringing short links beneath the accumulated stacks.

  • Patent number: 4236135
    Abstract: A motor overload protector or the like is disclosed in which a switch chamber is defined by a cup-shaped element and a header adhesively secured to the open mouth of the cup. A plurality of parallel support pins extend through and are adhered to the header to form a tight seal therewith. A flat continuous shoulder is provided within the housing which sharply intersects with the inner walls of the housing. One face of the header engages the shoulder and the edges of the header snugly engage a portion of the walls of the housing between the shoulder and the open mouth to form the switch chamber with the support pins extending into the chamber. A suitable plastic, such as epoxy resin, is provided in the space between the header and the open mouth to provide a tightly sealed switch chamber. A bimetal snap assembly is cantilever mounted by welding adjacent one of the support elements in the chamber and has a movable contact mounted on its free end.

  • Patent number: 4235378
    Abstract: A water play toy shaped in the form of an animal or cartoon character in which the body is provided with an outlet section which has a plurality of flexible hollow tubes attached to water outlets spaced around the outlet section. A source of water under pressure is coupled to a conduit passing through the body and communicates with the outlet section for distributing water to the hollow tubes. When the water pressure is turned on, a plurality of individual jets of water are emitted by the individual tubes. Because the tubes are flexible they writhe and twist in a random motion pattern due to the action and reaction forces of the water acting on the tubes. In one embodiment a first enclosed chamber compresses the outlet section. A second enclosed chamber is built into the upper interior portion of the first chamber which communicates with a small pinhole-type outlet to provide a misting or fogging aspect to the overall water pattern emitted by the water play toy.
