  • Waterways treatment composition and method
    Patent number: 4655814
    Abstract: The composition and method are for waterways, usually closed cycle, in which algae and the like is to be killed without harm to higher animal life. The composition includes a violet dye to enhance ultraviolet light penetration from the prevailing light to enter the waterway. This ultraviolet light, with reduction in visible light, causes algae death. It also increases free oxygen, neutralizes some toxins, and reduces admission of infrared radiation. The composition includes an enzyme which digests the dead algae and similar material. The products of digestion are such as to leave clean water. A blue dye may optionally be used to hide the violet color of the water in the visible part of the spectrum.

  • Buoyant blood stop valve
    Patent number: 4606365
    Abstract: This buoyant blood stop valve is in the blood line to the patient to stop flow to prevent air embolism when the blood is exhausted from the oxygenator reservoir.

  • Fill valve responsive to liquid level
    Patent number: 4522227
    Abstract: The fill valve is responsive to liquid level by passing vented vapor through serial orifices. The inlet flow is stopped by shifting a valve spool which is responsive to the pressure between the orifices. A pressure booster adjacent the vent outlet serves to momentarily shut off the outlet when pressure rises in the region of the second orifice to aid in shifting the main valve spool when system pressure is low.

  • Board game having rock, scissors, paper type theme
    Patent number: 4488727
    Abstract: Game apparatus comprises a game board together with a plurality of playing pieces each coded to indicate its attribute and value. Three playing pieces of different attributes and different values are stacked to comprise a playing unit.

  • Beam deflection system
    Patent number: 4395691
    Abstract: Deflection of an electron beam from axis 28 is controlled by electromagnetic deflection saddle coils 24, 26. Interference with deflection by surrounding mass of lens 22 is overcome by compensation coils 42, 44. The deflection coils and compensation coils are shaped and sized so that their own conductive properties do not distort the deflection magnetic fields. This is accomplished by equalizing between the deflection and compensation coils, the change in magnetic field during coil current penetration and by equalizing the penetration time constants for both sets of windings.
