Abstract: Disclosed is a wheelchair having a pair of levers along its opposite sides connected with sprockets on drive wheels. In one form, each lever is connected to its sprocket by a rack. The drive wheels have a clutch enabling the power stroke of the lever to drive the wheels through the rack-and-pinion engagement, yet permitting the sprocket to rotate in the reverse direction freely upon the return stroke of the lever. The rack includes an arcuate extent void of teeth to enable disengagement of the drive connection between the lever and sprocket whereby the wheels may move freely in either direction. In another form, a chain interconnects the lever and a return spring connected to the wheelchair frame. The chain has an extent void of pins to enable disengagement of the drive connection between the lever and sprocket, whereby the sprocket and, hence, drive wheel are free to rotate in either direction. A speed change mechanism is employed to vary the torque applied to the sprocket by the lever.

Abstract: The invention relates to an actuator, comprising:a cylinder,one or two pistons reciprocally movable in that cylinderone or two racks, each carried by a piston,a pinion coupled to the rack(s),an output connecting part coupled to that pinion for connecting to a device for driving, such as a butterfly valve,means for connecting to a line for medium under pressure for causing the pistons simultaneously to move towards or move away from one another, thereby causing the execution of a corresponding pivoting movement of the output connecting part, andresetting spring means for forcing the pistons into a terminal rest position.The invention provides an actuator with the feature that the resetting spring means comprise at least one gas spring which is connected between the cylinder and a piston. The advantage of the use of a gas spring is that within relatively precise limits it delivers a constant force over a very wide area, also therefore at the end of its stroke, whereby a reliable closure of a driven valve is better assured than is the case with the use of known screw springs. A gas spring also has the advantage of being obtainable in many embodiments after relatively simple adaptations with a view to connection to a known actuator and moreover of being easy to change from outside by a simple manual operation.

Abstract: A variable ratio rocker arm is provided for use in combination with the valve stem and push rod of an internal combustion engine. The rocker arm has an elongated slot defined between a rod seat and a toothed rack. A fulcrum rod is provided with a toothed sector and a curved sector, with the toothed sector being engaged with the toothed rack portion of the rocker arm. A roller bearing assembly is movably disposed between the rod curved sector and the rod seat, with the roller bearing assembly being rollable along the rod seat. An actuator arm is coupled to the fulcrum rod for simultaneously rotating and translating the fulcrum rod through the rocker arm slot. The operating arm causes the fulcrum rod to rotate and translate along the mating toothing from one point of pivotal engagement, corresponding to a first engine operating condition, to another point of pivotal engagement, corresponding to a second engine operating condition.

Abstract: A linear to rotary actuator is disclosed having a fluid pressure operated diaphragm whose linear movement is translated into rotary movement of an output member by a helical coupling therebetween. The coupling comprises a coupling member that is insert molded in the diaphram so as to extend therethrough and interlock therewith while preventing fluid from passing from one diaphragm side to the other. The coupling member has a combined guide and anti-rotation portion extending from one side of the diaphragm that slidably engages a stationary guide so as to guide linear movement while preventing rotational movement of the coupling member and further has a helix extending from the other side of the diaphragm that slidably engages in a slot in a section that meshes with a gear connected to the output member whereby linear movement of the diaphragm forces linear non-rotational movement of the coupling memmer and thereby rotary movement of the output member.

Abstract: A well pumping unit for use in association with an oil well, water well or the like having a downhole pump operated by a reciprocating pump rod with the pumping unit including a pair of large diameter rotatable wheels independently supported from upstanding supports on a deck, platform or skid with the wheels being interconnected by a pin to which a cable for operating the pump rod is attached. The cable is entrained over a series of pulleys and anchored to a supporting structure with one of the pulleys being a traveling pulley having a cable attached thereto extending over a head pulley and connected with the pump rod for reciprocating the pump rod when the wheels are rotated. The pin interconnecting the wheels is received in one of a plurality of radially spaced pairs of openings to enable the stroke of the pump to be varied by varying the radial position of the pin in relation to the rotational axis of the wheels. The wheels are driven by an electric motor with small pulleys and drive belts engaged with the large diameter wheels. A photovoltaic cell assembly may be used to charge batteries for storing electrical energy to drive the electric motor for powering the well pumping unit.

Abstract: A variable displacement vane pump is provided in which a pair of rings having oval-shaped inner contours are rotatably mounted in side-by-side relationship. The rings are adapted for relative rotation to each other from a first position wherein the inner contours are in register with each other and a moved position wherein the inner contours are out-of-register, and means are provided for effecting the relative rotation, which include a gear system operatively connected to the rings. A rotor member is mounted for rotation within the rings and is formed with a plurality of circumferentially spaced recesses which extend the entire axial length of the rotor. Each of the recesses carries a pair of vanes in abutting relationship. The vanes are mounted for radial movement in the recesses and are adapted for slidable contact with the inner contours of the rings. The vanes form two side-by-side rows of vanes with each row in tracking relationship with the inner contours of the rings. With the inner contours rotated to the first position, rotation of the vanes will pump a maximum volume of fluid through the pump and with the inner contours rotated to the moved position, the vanes will pump a reduced volume of fluid through the pump.
