The valve is a low pressure butterfly-type, 3-way, two-position, valve; including a recirculating path in the closed position which is opened by a convex-shaped disc carried on a stem which rotates on the main valve shaft in conjunction with the two butterfly halves.

Abstract: A highly destructive fuel-air type drop bomb which requires no retardation or restriction of its terminal velocity for efficient detonation; which utilizes a normally non-explosive, normally liquid fuel dispersed in air for its explosive power; which centrally carriers a low brisance heaving type fuel dispersing explosive surrounded by the body of liquid fuel; which includes a proximity fuse to detonate the low brisance explosive to break the fuel container and to disperse the fuel into the surrounding air in minute particles to form an aerosol cloud of large volume and of substantially uniform density in close proximity to the target; and which carries a time delay detonator for detonating the aerosol cloud after it has formed.

Abstract: A composite construction of a cylindrical tank with fabric covered end panels surrounded by a sheet metal circular frame, the longitudinal edges of the frame are formed inwardly engaging the edges of the tank while the lateral edges of the frame form a lapping joint with the exposed lateral edge shaped with an inward radius. Formed in the frame are a plurality of carrying strap supports, each of which includes a pair of slots cut in the frame having rounded ends.

Abstract: A system providing auxiliary power to the non-driving steerable wheels of a four-wheel vehicle utilizing hydraulic power in a parallel circuit from the existing hydrostatic drive system. The steerable wheels are driven by hydraulic motors connected in parallel through a flow divider valve and supplied by the variable displacement pump of the existing drive system through a selector valve which has a free-wheeling position allowing the steering wheels to free-wheel with the return oil from each motor flowing in a closed loop back through the flow divider valve while providing charging pressure to that closed loop circuit.

Abstract: Instrumentality for use in multiple spool control valve assemblies including a high pressure pilot operated relief valve that exhausts fluid from the chamber being protected through a pair of exhaust passages simultaneously. A pressure responsive flow restricting valve maintains a constant pressure differential on the control spools across the open center flow passages of open center valves. A low pressure regeneration circuit includes provisions for preventing excessive pressure and consequent seal blow-out in the return passages of a control valve assembly. Each of these instrumentalities is capable of being disposed in an end plate section of universal configuration for section control valve asssemblies.

Abstract: A pull type folding grain drill driven by the gauge wheels including pivoting legs carrying the gauge wheels which drive a clutch shaft through a first chain and sprocket drive, the clutch shaft axis being offset from the pivoting leg axis. A second chain and sprocket drive between the dispensing seed shaft and the clutch shaft including an idler pulley having cam means on the end thereof for disengaging a clutch on the clutch shaft when the pivoting legs are rotated to lift the planter out of the ground in the transport position.

Abstract: A notching machine including a first cutting stage which makes four vertical cuts in the stringer, the outer two cuts defining the sides of the notch. The second cutting stage of the machine makes a horizontal cut which first separates a portion of the stringer between the inner two cuts thereby allowing the drive shaft of the second-stage cutting blade to pass through the partially formed notch and cut away the remaining portions of the stringer between the outer two cuts to define the notch.

Abstract: A fuel-air type bomb which contains a liquid fuel normally non-explosive, with a bursting charge centrally located within the fuel; the bursting charge, upon firing, shocks the fuel into a highly reactive mixture with the surrounding air while simultaneously disseminating the fuel at a supersonic rate over a large area, which causes increasing blast effects.

Abstract: A highly destructive fuel-air type drop bomb which requires no retardation or restriction of its terminal velocity for efficient detonation; which utilizes a normally non-explosive, normally liquid fuel dispersed in air for its explosive power; which centrally carries a low brisance heaving type fuel dispersing explosive surrounded by the body of liquid fuel; which includes a proximity fuse to detonate the low brisance explosive to break the fuel container and to disperse the fuel into the surrounding air in minute particles to form an aerosol cloud of large volume and of substantially uniform density in close proximity to the target; and which carries a time delay detonator for detonating the aerosol cloud after it has formed.

Abstract: A hydrostatic parallel circuit drive system on a vehicle which drives a pair of hydraulic wheel motors which are supplied by a single pump source through a divider valve which senses the flow rate to each of the motors, and when the flow rates to the two motors vary sufficiently, the divider valve restricts the excess flow so that one wheel cannot spin and consume the entire flow to the system.

Abstract: A hand-operated hydraulic pump utilized to lift or trim an outboard marine engine. A wobble-action handle connects with a pinion gear which in turn drives a rack on a double-ended piston forming two cylinder chambers on opposite ends thereof. Reciprocal movement of the piston alternately pumps fluid from each cylinder chamber both of which are supplied by a common longitudinal passage in the piston across a pair of check valves located at each end of the piston. The pump housing includes the reservoir, discharge port and needle valve for relieving fluid from the discharge port back to the reservoir.

Abstract: A picnic table and seat structure having a table top and a plurality of tubular legs shaped in a pedestal form with the feet of the legs outwardly turned to support individual seats. The center sections of the legs are banded together around a center post which supports the table top and spreads the legs.

Abstract: A device to facilitate use of scaffolding during construction of wood frame buildings by using a light-weight metal channel attached to and encasing occasional studs. Brackets hook into the channels at various desired heights, supporting planks which provide the working surface. At outside corners, one bracket hooks into the side of another at right angles to provide a scaffold in both directions from the corner using but one vertical channel. Channels are left in place and covered up as the siding is applied.

Abstract: A hydraulic control valve in a closed-center load responsive system having a passage with a check valve therein downstream of the inlet metering and signal passage allowing flow from the signal passage to the load prior to connecting the pressure circuit to the load circuit so as to relieve fluid from the signal circuit to the load circuit as the signal circuit attains a pressure higher than the existing load thus causing flow past the inlet metering whereby the pressure differential in the metering compensates the pump.

Abstract: A priority valve utilized in a pressure and flow compensated variable displacement system which supplies priority flow to a priority motor and secondary flow to a secondary motor as long as the priority flow requirements are satisfied or the priority flow path is blocked. The priority valve utilizes the same flow control signal as the system pump including a fixed restriction in the signal line and a relief valve downstream of said restriction, set at a level below the maximum pressure level of the system so that when the priority motor is stopped, flow continues to the secondary motor.
