  • Patent number: 6826355
    Abstract: A toy gun produces a series of traveling smoke rings. It has a smoke chamber fed with smoke from a battery-powered electrical resistance generator. An elastic, edge-mounted diaphragm extends across at least a portion of the rear of the smoke chamber. A reciprocating actuator movable in response to a trigger strikes the diaphragm to eject a smoke ring through an orifice in the opposite wall of the smoke chamber. The smoke generator includes a supply tank of a suitable liquid and a source of variable pressure to drive the liquid through a narrow annular clearance to the heater where it is rapidly vaporized. The generator includes a pair of concentric tubes that define the annular clearance and an electrical resistance heating element mounted on one of them at a point spaced from the supply tank. The generator also includes a spacer and a member that increases the length of the flow path of the fluid driven through the narrow annular gap.

  • Patent number: 6815647
    Abstract: A heat treatment unit comprises a heat plate made of aluminum nitride which is excellent in heat conductivity and strength inside thereof. The entire circumference of the heat plate is supported by a supporting member which is excellent in thermal insulation.

  • Patent number: 6806444
    Abstract: Heat alert safety device for warning individuals that a surface is hot wherein a fiber optic cable runs from an electric light source to a heat warning symbol. The cable has a plurality of fibers connected at a first end thereof to the light source and transmits light from the light source beginning from the first end to the second end of the cable and shines light out of the second end of the cable to a predetermined symbol adjacent the second end of the cable. The symbol is readily visible when illuminated to an observer who can also readily see the surface and the symbol communicates that the surface of the stove, in particular, the heating element, is dangerously hot. A controller controls the light source. Whenever a specified surface temperature is reached, the symbol is lit and remains lit as long as said specified surface temperature is maintained.

  • Patent number: 6792302
    Abstract: A method and apparatus for evaluating acute stroke patients and for determining whether a stroke patient will benefit from the use of thrombolysis therapy includes obtaining measurements of the cerebral blood flow and cerebral blood volume of the brain of a stroke patient, determining ischemic areas of the brain where the ischemic areas comprise the measurements of cerebral blood flow which are less than a first value and creating a penumbra-infarct map of the ischemic areas of the brain using the measurements. The infarct area corresponds to the area of the brain where cerebral blood volume is less than a second value. The penumbra area corresponds to the area of the brain where cerebral blood volume is greater than this second value. The method also includes determining a ratio of penumbra size to the total of penumbra size and infarct size. When the ratio is greater than a predetermined value, the stroke patient is a candidate for thrombolysis therapy.
