  • Patent number: 6004116
    Abstract: An automatic air pump is built into an inflatable body. The automatic air pump includes a pump body, an air inlet and an air outlet. The pump body is automatically restorable and has an air chamber inside. The air outlet is provided on the pump body to introduce air into the inflatable body when the pump body is pressed. The air inlet is provided on the inflatable body to suck air outside the inflatable body into the pump body when the pump body is released.

  • Patent number: 5924142
    Abstract: An automatic dispensing system dispenses chemical directly into a toilet bowl after the toilet bowl is flushed and includes a chemical dispenser and a hydraulic actuator. The chemical dispenser includes a pumping unit attached to a storage unit for storing a chemical cleaning and/or disinfecting solution. The chemical dispenser is attached to the hydraulic actuator, which is in turn attached to the overflow pipe in the tank of the toilet. The hydraulic actuator is also connected to a toilet bowl refill hose. During the flushing process, pressurized water controlled by a water level control unit is used to refill the toilet tank. Some of this water is shunted to the hydraulic actuator assembly. In response to the flow of pressurized water, the hydraulic actuator actuates the pumping unit to measure out a predetermined amount of chemical. When the toilet tank is refilled, the flow of pressurized water is stopped.

  • Patent number: 5890382
    Abstract: A multishaft combination lock includes a lock body, an alignment sleeve, and a detachable pin. The alignment sleeve has a hole and is rotatably coupled to the lock body to provide access into the lock body. The alignment sleeve has an angled cutout at a first end, with the alignment of the cutout being adjusted by rotating the alignment sleeve. The detachable pin has a floating bushing that can be misaligned with the principle axis of the detachable pin. To lock the multishaft combination lock, the lock body is fitted to the detachable pin through the hole of the alignment sleeve with the floating bushing misaligned with the angled cutout. When the detachable pin is fully inserted into the lock body, the floating bushing is positioned beyond the end of the alignment sleeve within the lock body and becomes misaligned or offset with the alignment sleeve. To unlock the lock, the alignment sleeve is rotated so that the angled cutout is aligned with the floating bushing of the detachable pin.

  • Patent number: 5827052
    Abstract: An air pump comprises a hollow pump body, at least one pulling member, an air inlet and an air outlet. The hollow pump body has air inside and consists of flexible sides and two opposite stiff ends. The air outlet is provided on the pump body to discharge the air in the pump body when the pump body is pressed. The pulling member is attached to one of the stiff ends of the pump body in order to restore the pressed pump body by pulling the pulling member. The air inlet is provided on the pump body to suck outside air into the pump body when the stiff end is pulled by the pulling member to restore the shape of the pressed pump body.

  • Patent number: 5713294
    Abstract: An inflatable boat comprises an inflatable body, at least one inflatable wing member and at least one holding device. The inflatable wing member is attached onto the inflatable body, while the holding device is connected to the inflatable wing member. Furthermore, the inflatable wing member has a rowing plate on which at least one check valve is provided. The inflatable boat can go ahead on a surface of water when the inflatable wing member is pulled by the holding device to paddle the water.

  • Patent number: 5091971
    Abstract: A method and apparatus for modifying an image data signal has a serial channel for obtaining a desired number of current M-bit patterns from the image data. Unique bit patterns are recognized in the current bit patterns, and new bit patterns are generated, each being specific to the detected unique bit pattern. The current and new bit patterns are combined in a predetermined manner to modify the image data as desired. For example, if the unique bit patterns are recognized as dark images on a leading edge of an image, the new bit patterns are generated and combined with the current bit patterns to lighten the image, particularly at the leading edge to improve stripping of the print media on which the image is printed from a fuser roll of the printer.
