  • Patent number: 4416589
    Abstract: A positive displacement liquid pump having a free-moving weight mass spaced from and oscillatably positioned concentrically within a cylindrical housing is disclosed. A pair of cooperating one-way valves, one valve communicating with a central passage defined by the weight mass while the other valve communicates with an inlet to the housing, coact to draw in fluid or liquid from a supply source. As the oscillatable weight mass moves away from the inlet, the one-way inlet valve opens, filling a chamber behind the weight mass. The one-way valve in the weight mass simultaneously closes enabling the weight mass to drive fluid out of the reservoir chamber at an exit end of the housing, the valves acting oppositely when the weight mass oscillates back toward the housing inlet. The free-moving weight mass suspended within the pump housing is set in motion by the oscillatory motion of a vibration source without direct mechanical actuation of the device from a power source.

  • Patent number: 4412786
    Abstract: This invention relates to a positive displacement pump. The pump utilizes a source of rotary motion in the back and forth, clockwise, counterclockwise direction. The rotary oscillatory motion drives an annular piston weight mass in a toroidal rotary track, back and forth within the track in combination with at least a pair of one-way valves to pump fluid through the pump. Specially designed electric motors that rock back and forth, without a 360.degree. rotation, for example, may be coupled to a positive displacement pump of this invention. In the medical profession, this pump may be used to pump liquids at a very slow, precise rate to transmit, for example, a variety of medications into a patient.

  • Patent number: 4406587
    Abstract: A positive displacement liquid pump having a free stroking piston slidably positioned within a cylindrical housing is disclosed. A pair of cooperating one-way valves, one valve communicating with a central passage defined by the piston while the other valve communicates with an inlet to the housing, coact to draw in fluid from a source of liquid. As the piston moves away from the inlet the one-way inlet valve opens filling a chamber behind the piston. The one-way valve in the piston simultaneously closes enabling the piston to drive fluid out of the reservoir chamber at an exit end of the housing, the valves acting oppositely when the piston oscillates back toward the housing inlet. The free stroking piston within the pump is set in motion by the oscillatory motion of vibration alone without direct mechanical piston actuation from a power source. The pump may cooperate with a fluid regulator to control flow of fluid from the pump housing.

  • Patent number: 4362520
    Abstract: This invention is a heavy-duty flexible shaft that accommodates for misalignments between an input and output shaft. The flexible shaft is comprised of a multiplicity of hollow, individually fabricated, interfitting members housed in a tubular, bendable shaft. Each segment is intimately engaged, one within the other, yet the segments are so designed to allow for limited longitudinal movement while restricting circumferential movement between segments during torsional transmissions from the input to the output shafts.

  • Patent number: 4336449
    Abstract: A garment tag reading system which includes a Kimball tag reader and a data processing unit is described for reading and decoding information encoded on a garment tag. An interface unit is used to permit direct communication between the tag reader, which has a memory for storing the coded information read from the garment tag, and the data processing unit. The interface unit includes a column driver having a plurality of low voltage amplifiers which provide amplified output voltages in response to voltage-level increases caused by the programmed operation of the data processing unit. The output voltages are serially applied to the tag reader memory for interrogating the memory to retrieve the coded information. The information from the tag reader memory is received by a data input/output circuit in the interface unit in the form of decimal coded output voltages and is subsequently entered into the data processing unit for decoding into a readable format.

  • Patent number: 4305361
    Abstract: A two cycle internal combustion engine with improved cylinder scavenging. The described engine embodiment is a baffled piston two cycle internal combustion engine whose power is substantially increased by directing fuel mixture in the normally spent gas filled region behind the piston baffle during each intake-exhaust portion of the engine cycles to scavenge spent gas from this region and increase the total volume of fuel mixture in the cylinder at the time of ignition. According to the preferred practice of the invention a portion of the fuel mixture displaced from the engine crankcase to the cylinder intake port or ports is diverted to auxiliary ports in the cylinder wall which direct the mixture against the rear side of the piston baffle to effect through scavenging of the region directly behind the baffle.

  • Patent number: 4265626
    Abstract: A trimming wedge is disclosed to trim a propeller driven boat for better performance. The wedge is fixed at its base to the center shaft housing of a propeller driven power boat. The trimming wedge extends approximately the length of one blade of the propeller and is positioned in front of and in line with the propeller blade. The trimming wedge or vane splits the water in front of the propeller so that the blade of the propeller passes through a void in the water. For example, when the wedge is positioned vertically downwardly from the shaft housing, the void occurs when the clockwise arc of the blade is in about the downward four o'clock to eight o'clock position when viewed from the rear. A trimming wedge with the proper wedge angle neutralizes the tendency of the propeller to "walk" the boat sideways or to the right with a clockwise turning propeller, thus transferring the side load thrust to forward thrust when the boat is propelled through the water, resulting in an increase in forward speed.

  • Patent number: 3967606
    Abstract: A fuel pump for an internal combustion engine of the type wherein cyclic pressure fluctuations are produced in the engine crankcase chamber during engine operation by the reciprocating motion of an engine piston. The pump embodies fuel pumping means including a pulsatory pumping member or pulsator, such as a diaphragm, and is mounted directly on the engine with the pumping pulsator exposed directly to the engine crankcase chamber in such a way that the chamber pressure fluctuations drive the pulsator in its pulsating pumping motion to pump fuel from the fuel inlet to the fuel outlet of the pump. Also embodied in the pump are a novel fuel pressure regulating valve for maintaining a substantially constant fuel outlet pressure regardless of engine speed and an automatic fuel shut-off valve for blocking fuel leakage through the pump under the action of head pressure or other forces when engine operation ceases.
