Abstract: A method for providing resistance to flow through a flow passageway comprises partially blocking flow through an orifice of reduced diameter by masking the orifice with an element formed of porous material retained immediately adjacent to every side of the orifice that is expected to be exposed to higher pressure fluid with a greater surface area of the porous masking element being exposed to fluid in the passageway on the higher pressure side of the orifice than is exposed by the orifice to the lower pressure fluid. The orifice may be formed by direct configuration of the passageway walls or by a body adapted to retain the masking element in the body, the outside of the body being adapted to for secure installation within the flow passageway. Resistors in accordance with the present method may have masking elements on one side for use with one directional pressure differentials or masking elements on both sides for use in applications in which bidirectional pressure differentials are anticipated.

Abstract: A fluid resistor for providing resistance to flow through a flow passageway is formed by cutting channels and open cylindrical recesses on the surface of and flow passage bores through a frusta-conical body to be seated in a tapered passageway section with the larger diameter end generally subject to higher system pressures than the smaller diameter end. The seating of the resistor body in a tapered passageway section seals and encloses the channels and recesses which then with the fluid passageways through the resistor body, comprise a restricted path for flow to proceed past the installed resistor, the recesses forming cylindrical chambers.

The transfer disks are releasibly engageable with power take off wheel and drive wheel.

Abstract: A solenoid drive circuit comprises a timing circuit which activates a voltage control circuit causing a voltage regulator to reduce the voltage output by the driver circuit from a high initial level to a lower holding level sufficient for the solenoid to remain energized. The timing circuit comprises a resistor and capacitor in parallel and the duration of the initial higher voltage output is inversely proportional to the input voltage level. The timing circuit activates a transister in the control circuit changing the equivalent resistance between the adjustment terminal of the voltage regulator and ground thereby causing a reduction in the output voltage.

Abstract: A loading ramp mechanism comprises two ramps and the support system therefor such that the ramps may be moved from a storage position in which the ramps are on edge and horizontal and parallel proximate to each other below the rear edge of a truck load bed, to a deployed position in which the ramps are secured at one end at the rear of the cargo bed of the small truck and are laterally adjustable. The support system comprises two support rods each having two sections flexibly joined, the first section being rigidly mounted in a vertical position and the second section being releasably supported in a horizontal position and capable of assuming a vertical position on the same axis with the first vertical section. Each ramp member at one end slidably receives a support rod and can be supported by either the horizontal second section when deployed or the vertical first section when stored.

Abstract: A pump for dispensing accurately measured amounts of fluid has a one way check valve in the flow path on the upstream side of a pump chamber and a one way check valve in the flow path at the downstream side of the pump chamber which is of variable internal volume. A flow passage provides fluid communication from the upstream check valve to the pump chamber and enters the pump chamber by a centrally located opening that is surrounded by a valve seat. One wall of the pump chamber is a flexible and elastic diaphragm that is attached to the plunger portion of a solenoid actuator. The plunger and diaphragm are biased by a spring acting upon the plunger such that, in the absence of excitation of the solenoid coil, the diaphragm is biased against a valve seat, preventing flow through the pump.

Abstract: A variable stroke mechanism provides a means for varying the stroke and leverage of a linkage between reciprocating power source and crankshaft. The mechanism includes a lever connected at one end to the reciprocating power source and at the other end to the crankshaft with a variable fulcrum point between the two ends. The lever forms a longitudinally extending slot for containing a fulcrum member, the other surfaces of which, while generally cylindrical, secures a series of parallel and equiangularly displaced cylindrical roller bearings. The top of the slot formed within the lever is a flat bearing surface and the opposing bottom surface contains a series of semicircular channels forming a gear train sized and located to successively engage the roller bearings on the fulcrum member and said bearings serving as gear teeth such that rotation of the fulcrum member changes the position of the fulcrum point relative to the lever.

A second embodiment of the lure is generally configured to present an outward appearance similar to that of a crayfish. The second embodiment of the lure is drawn through the water tail first and configured such that the swimmerets are fanned and extend in a downward angle to serve as a diving plane when the lure is drawn through the water.

Abstract: An expansion sealing plug having a frusto-conical plug body with peripheral U-shaped grooves, an expansion member comprising either an inner wedge pin or a spherical member, and a tapered coaxial bore for receiving the expansion member. The inner wedge pin has a greater average outside diameter and the spherical member has a greater maximum outside diameter than the tapered coaxial bore. The plug body and expansion member are proportioned to be readily preassembled such that the expansion member is frictionally retained after partial insertion into the plug body. The unexpanded plug is inserted into a counterbore that is reamed or formed with the same taper angle as the plug body and the expansion member is driven axially into the plug such that the plug body is radially expanded to forcibly engage the counterbore.

Abstract: A device for providing a sealed intersection between flow passages within a housing comprises an expansion sleeve with a cylindrical outer surface and an axially tapered inner surface for receiving a frusto-conical inner member of greater average diameter and the expansion sleeve is radially expanded in place after insertion into the installation bore, by the forcible insertion therein of the inner member. No interference occurs between the sleeve and the installation bore until after the sleeve is in place in the bore. The outer surface of the sleeve is reduced or not as many be desired to provide fluid communication among the flow passages. Two embodiments differ in that one seals between axially separated ports while the other seals between angularly separated ports.

The valve actuator further comprises a cylindrical housing encasing in coil wound around the bobbin with a central passage configured to allow the flow of fluid around the armature and pole piece when the valve is open, the pole piece, armature housing and end piece being magnetically permeable and the magnetic circuit being completed by a similarly magnetically permeable washer fitted into the housing having an internal opening diameter greater than the diameter of the plunger rod section and less than the diameter of the plunger head section positioned on the bobbin side of the plunger head.

Abstract: A device for removably retaining a fluid system component in a smooth bore comprises of body on one end of which the component is mounted and the other end of which comprises a plurality of wings. The interior of the body provides female screw threads into which an expansion member is engaged, said expansion member having male screw threads at one end and at the other end a truncated conical section. Rotation of the expansion member relative to the body causes further insertion for expansion member into the body such that the conical section causes the wing members to radially expand and engage the wall of the installation bore. The device is generally cylindrical in overall configuration with an outside diameter at least slightly less than the inside diameter of the installation bore and upon retraction of the expansion member from forcible engagement with the body, the wing members relax to their original state and the device can then be readily removed from the installation bore.

Abstract: A fluid control valve comprises a slidable, tubular poppet member that is biased toward and sealingly engages dual concentric annular valve seats, which valve seats define an annular opening through which the fluid medium flows when the valve is open. When the system pressure reaches a threshold pressure the poppet member is axially displaced from the valve seats such that an annular orifice is opened between the inside edge of the poppet and the inside valve seat and another orifice is formed between the outside edge of the poppet and the outside valve seat through which orifices the fluid medium flows into a central, axially extending relief path partially defined by the inside of the poppet. The dual orifices allow the valve to open with a stroke that is about one-half that of that required in a valve with only one orifice and similar operating range.

Abstract: A check valve that allows flow in one direction only and is suitable for controlling corrosive, chemically active or sensitive fluids comprises a body formed of a suitably inert substance defining inlet and outlet flow passages with a central chamber between the flow passages and an elastomeric disc traversing the central chamber. Centrally located disc stops bias the disc against an annular valve seat comprising a ridge surrounding the flow path and the sealing engagement of the disc and the valve seat prevents flow through the valve. An increase of the pressure differential across the disc sufficient to overcome the resilience of the disc causes the disc to deform whereby the perimeter of the disc lifts off the valve seat and allows flow through the valve. Support stops are provided at the inlet end of the central chamber to prevent the disc from being forced into the inlet flow passage upon exposure to a high back pressure differential.
