  • Patent number: 5177073
    Abstract: A therapeutic composition derived from a pre-activated photoactive compound and a conveyor for destroying tumor or other pathogenic biological contaminants infecting animal body tissues. The conveyor can either be a matrix support or an antibody. The activation of the photoactive compound to produce the pre-activated photoactive compound is carried out by the use of an activating agent. The pre-activated photoactive compound retains its therapeutic activity subsequent to activation. A method for preparing such a therapeutic composition is disclosed. Methods for treating animal body tissue, either outside the body or inside the body, infected with tumors or other pathogenic biological contaminants are disclosed.

  • Patent number: 4918357
    Abstract: A dual-filament light bulb with associated adapter apparatus which uses photovoltaic cells mounted within the light bulb to charge a battery which powers one of the filaments. The adapter apparatus is designed to mount in an ordinary light socket which provides external current to the other filament. The adapter apparatus includes circuitry which alternately switches from the filament powered by the battery to the filament powered by external current in a manner which reduces the amount of electricity needed to produce a given amount of light.

  • Patent number: 4888833
    Abstract: This invention provides a cart for positioning an individual's body on a toilet. It is particularly advantageous for transporting a handicapped person to such toilet and automatically aligning the handicapped person's body above the toilet. The cart has castors for easy rolling and also has guiding rollers that center the individual's body over the toilet when the cart is rolled backwardly over the toilet. The invention also incorporates a pneumatic system for raising the individual's body above the height of the toilet's seat when the body is pushed over the toilet and for, subsequently, lowering the individual's body onto the toilet seat in a position that enables use of the toilet by the individual.

  • Patent number: 4747402
    Abstract: A method of ventilating an air breathing animal at a high frequency. A flow of gas is supplied to the first side of a piston mounted within a housing while the flow of gas out of the housing is restricted to elevate the pressure on the first side of the piston. A flow of gas is also supplied to the second side of the piston, which is connected to an air breathing animal, while the piston is alternately moved back and forth within the housing at a selected frequency, amplitude and period, thereby alternately forcing gas into and drawing gas out of the animal. The flow of gas out of the animal is also restricted to elevate the pressure on the second side of the piston. The flow of gas to the first side of the piston both cools the piston and housing and helps to equalize the pressures on both sides of the piston, helping to insure accurate conversion of the mechanical movement of the piston into a pressure wave in the gas on the second side of the piston.

  • Patent number: 4746826
    Abstract: An electromagnetic clutch apparatus for providing a reversible mechanical linkage between a driving motor and its mechanical load and which is particularly well suited for use as part of an electrically actuatable automotive cruise control system. The apparatus is inherently self-disengaging, thereby limiting the maximum mechanical load against which the driving motor may operate. The apparatus is designed to be placed between the final output gear of a gear train and the engine throttle and yet overcomes the problems associated with such a placement because the mechanical torque which the clutch is designed to transmit is not directly related to the electromagnetic force required to keep the clutch engaged.

  • Patent number: 4732297
    Abstract: A liquid concentrate dispensing apparatus having a removable and refillable concentrate tank with sensors connected therewith flush with the inside wall of the tank to facilitate cleaning. The sensors comprise detectors which include an electrically conductive housing, one wall of the housing is substantially flush with the inside wall of the tank. Spring biased detent members on the outside of the tank releasably connect the detectors with the dispensing apparatus when the tank is inserted to a preselected position. The tank is provided with two such sensors, one is located in the sidewall and the other is located in the bottom wall. When the tank is inserted into the dispensing apparatus, the spring biased detent members engage contacts on the apparatus. A current passes between the detectors on the sidewall and bottom wall when both are covered by liquid concentrate.
