  • Patent number: 6808331
    Abstract: The fluid delivery/refilling system includes a unit-of-use fluid reservoir for dentifrice or medication within a head portion of a power toothbrush, which is removable from the remainder thereof. A pump element is located in the brushhead and is configured so that the back and forth movement of the brushhead in operation results in fluid moving from the reservoir to a dispensing valve located in the brushhead. The dispensing valve has an end portion which is normally closed, opening under pressure of fluid from the pump. The refilling assembly is separate from the toothbrush and is configured to fit over the top of the toothbrush. Upward pressure exerted on the toothbrush when the toothbrush is within the refilling assembly results in movement of a core element in the refilling assembly, which in turn results in a hollow needle in the refilling assembly extending into a refiller valve in the head portion of the toothbrush.

    Abstract: A dry foaming coin operated carpet and upholstery cleaning machine for a car washes. A rigid, generally box-like cabinet is secured in a convenient user accessible position. An elongated hose extending from the housing terminates in a user-activated brush which outputs foam and facilitates vigorous cleaning. The control circuit comprises a conventional coin mechanism which operates a timer to initiate a vend. The timer first activates an air compressor, which supplies high pressure air to the system. A remote user switch associated with the brush must be activated to thereafter activate a pump to supply cleaning solution, and to close an air solenoid for air mixing. Simultaneously a heater is activated to heat the control block disposed within the brush. A brush control block properly mixes air and cleaning solution. An elongated heater compartment preheats incoming air, which is thereafter mixed with cleaning solution and discharged through a foam generating chamber in the block.

  • Patent number: 4708506
    Abstract: An ink supply system for writing instruments which operate with liquid ink. The writing instrument has a large-volume ink reservoir which communicates via a recharge valve with a small-volume ink reservoir which is adjacent to the writing element. The transmission of ink from the large-volume ink reservoir to the secondary reservoir is controlled by a sensor as a function of the quantity of ink which is present in the secondary ink reservoir. In order to simplify the recharging of the ink, and to be able to operate with the least possible electrical energy, the present invention utilizes as a recharge valve a tube pump which is rotatably driven by an electric motor and also can generate the pressure necessary to convey the ink to the secondary ink reservoir.

  • Patent number: 4540301
    Abstract: A peristaltic-type pump having an intake which may be conveniently connected to a liquid coating source includes an impeller having a pair of rollers. Rotation of the impeller causes the rollers to progressively compress a length of tubing in the pump. This compression creates suction to draw the coating material into the pump and pressure to drive a flow of coating to a handle attached to an applicator. The handle includes flow control devices which may be selectively operated to supply coating to the applicator only as required. During periods of non-flow the coating pressure is sensed to deactivate the pump when the pressure exceeds a preselected limit. Deactivation of the pump saves energy and prolongs a life of the pump.
