  • Patent number: 6367371
    Abstract: A food processing device for automatically cooking and processing food is shown. The device has a cylindrical cooking vessel positioned in a sloping manner and rotatably supported on rotary wheels. Variable heater elements are provided at the cooking vessel to subject the food to selected cooking heat patterns. The food advances through the cooking vessel by gravitational force and the rotational movement of the vessel and it is also being tossed and turned continuously to ensure even cooking and from adhering to the inner side wall of the vessel.

  • Patent number: 6246033
    Abstract: A method and device for controlling and limiting the cooking temperature of any selected utensil for cooking on a surface burner element of a range are shown. A temperature sensor is provided either on a heat transfer plate which is mounted to the burner element or in a remote-controlled unit mounted directly to the utensil. The actual temperature of the utensil is compared with the selected cooking temperature, and it is then adjusted to maintain the two temperatures close to each other. The device also automatically turns off the burner element in a potential runaway condition or in the absence of a utensil placed thereon.

  • Patent number: 6209596
    Abstract: This device is for maintaining a flexible bag in an open manner. It has an inner hoop having an outer side wall sloping inwardly and downwardly, and an outer binder which is provided with a through opening having a complementary shape and size adapted to embrace the outer side wall of the inner hoop. The flexible bag is mounted between the inner hoop and the outer binder by first inserting the bag through the inner hoop with the bag's lip portion folded backwards to cover over the outer side wall of the inner loop. The outer binder is then fitted over the inner hoop with the folded back lip portion of the bag sandwiched between the engaging inner hoop and the outer binder. When the bag is being filled, the weight in the bag will inherently pull the inner hoop and the outer binder to engage with each other with increasing force as the weight of the load increases, and thus, in turn, securing the bag even more tightly to the device.

  • Patent number: 6184605
    Abstract: This device converts the intrinsic magnetic force of permanent magnets into a useful output. The three-pole permanent magnets configuration comprises of two elongated bar magnets (1,2) having two opposite magnetic polarities divided by a longitudinal plane. One magnet (1) is referred to as the movable magnet and the other magnet (2) is referred to as the stationary magnet and is located juxtaposed and perpendicular to a broad side surface of the movable magnet. The interaction of the intrinsic magnetic forces of the two magnets (1,2) results in a torque forcing the movable magnet to move in its longitudinal direction (37) relative to the stationary magnet. A plurality of such three-pole permanent magnets configurations are provided around the periphery of a rotary wheel (8) to provide a rotary torque output.

  • Patent number: 6035455
    Abstract: The portable power plunger is for unclogging blocked drains in sinks, toilets, bath tubs and the like. The plunger has a main body having a reciprocating pump with a removable attachment mounted at its outlet lower end which is adapted to cover intimately over the waste water drain of a sink, toilet, or bath tub. The drain may be unclogged by operating the pump to dislodge the blockage and to dispose of it down the sewer. The pump is provided with a substantial back flow preventor such that the dirty water in the drain would not back into the pump to contaminate the latter. An integral injector pipe is also provided on the plunger. The injector pipe extends into an interior compartment at the lower part of the housing between the back flow preventor and the outlet, and it is attached to a pneumatic pressure source or pressurized water supply. The pneumatic pressure or pressurized water provides additional pressure to unclog the blockage in the drain or for drawing dirty water out from the drain.
