  • Patent number: 5563850
    Abstract: A device for mounting on the wrist of an individual. The device includes a motion-sensing element that is coupled to and starts a timing unit when the wrist is moved--as in raising an utensil of food to the mouth. The timing unit is coupled to a signal generator that it actuates after a given interval of time. The signal generator actuates an annunciator unit, in contact with the wrist of the individual, that produces a tangible sensation on the wrist of the individual to advise the individual that it is time for more food, and that the cycle can be repeated. The tangible sensation may be a physical prodding or and electrical stimulus, but it must not be apparent to anyone but the individual. The given interval may be adjusted to the needs of the individual.

  • Patent number: 5511622
    Abstract: A small hollow device extends through the wall of an engine compartment or box. It can be secured to the box by a flange around its outside edge attached to the wall of the engine box. A stop or valve, in the shape of the hollow device, is fitted into the hollow portion of the device, and may be held by another flange inside the wall of the box, to seal it in normal operation. However, this stop is secured within the hollow portion of the device by a flexible coupling that holds the stop in place in normal operation, but allows it to move to an open position when the nozzle of a fire extinguisher is pushed against it. This permits a fire within the engine box to be extinguished quickly and safely without the necessity of opening the lids of the box, which would admit large quantities of air to feed the combustion and flames.

  • Patent number: 5403230
    Abstract: A device for opening the shells of crustaceans has an inner portion and an outer portion extending from a handle section at one end to a cutting section at the other end. In the cutting section, the inner portion has a sharpened end at the start of a cutting or fracturing edge that tapers upward toward the handle. The cutting section of the outer portion has sides that taper downward on each side of the cutting edge toward the handle, overlapping the cutting edge about halfway down. The outer portion fits loosely over the inner portion, to be removable for cleaning etc. The inner portion cutting edge thickens as it tapers upward for increased strength in cutting harder shells, and the sides of the outer portion cutting section become fulcrums when the handle is raised to lever the cutting edge of the inner portion through the crustacean's shell to expose the shellfish meat.

  • Patent number: 5385108
    Abstract: An automatic valve is attached to the lower edge of the transom of a boat. The valve is a short tubular device that is aligned with a hole in the transom and mounted on the transom in a substantially horizontal plane, in a watertight manner. The inner end of the device may follow the slope of the transom. However, a cap, hinged at its top, covers and seals the outer end of the device, and the bottom of the outer end projects out beyond the top to provide enough slope for the cap to be held by gravity against the outer end. This closes the valve against water pressure from the outside, but allows bilge water to flow out when there is no external pressure. The valve may be, normally, under water, but can drain the bilge when the hull is out of water, or moving quickly enough through the water to clear the transom.

  • Patent number: 5292314
    Abstract: A syringe has a needle mounted in the lower end of a tubular mount. A protective cover, in the form of a sleeve, fits over this lower end of the tubular mount, and extends to fully cover the sharp end of the needle. The tubular mount has a pair of elongated, axial slots for the entry and exit of a cog or lug on the inside of the sleeve. Pressure on the sleeve slides the lug up the entry slot and exposes the needle. A cross over slot carries the lug to the exit slot, where it slides down to the lower end of the mount, and over a locking ridge to automatically and securely recover the needle. A spring, coupled between the mount and the sleeve has an axial force urging the sleeve down in either slot, and a rotary force urging the cog towards the exit slot. The lug must be in the entry slot to depress and use the needle, but the lug is then rotated to the exit slot and returned by the spring, automatically, to lock the lug in the safe, covering position of the sleeve.

  • Patent number: 5273466
    Abstract: A tubular vent device extends through a hole in the hull of a boat, well above the water line. The outer portion of the vent device has a circular ridge or shoulder larger than the hole through the hull to hold the outer portion outside of the hull. The inner portion is threaded to accomodate an inner nut with a collar or washer larger than the hole to let the nut draw the inner collar and outer shoulder tight against their opposing sides of the hull. The inner portion terminates in a coupling for a hose to connect to a tank to be vented. The outer portion of the vent, beyond the shoulder, is also threaded to receive a cap that has a series of fine, axial slots through its outer surface for ventilation. The end of the outer portion of the vent also has a tapered conical portion within the cap, with a pair of axial ridges on the outside just above a pair of axial ventilating slots that open the tubular vent to the fine slots in the cap.

  • Patent number: 5148774
    Abstract: A framework, of the general size and shape of an enclosed litter box, is designed to fit within a plastic bag of a comparable size and shape, so that it can rest on its side on the floor to provide a litter box. The framework may be of solid panels, or open mesh, or even wire forming the necessary shape. However, it must form the bag into a top, sides, rear, and bottom sections, with an open front section adjacent to the opening of the bag. While the top, sides and even the back of the framework may be solid, the bottom must be open so that the plastic surface of the bag along the bottom can be covered with litter to accommodate its proscribed function. The front must also be open to allow an animal to enter through the opening of the bag. The entire structure may be fit into a shallow pan that can support the bottom of the bag containing the litter and hold the framework above the litter.

  • Patent number: 5140876
    Abstract: A pair of pliers has two opposingly curved halves to form jaws on one end and handles on the other end. One of the halves includes a primary, fised pivot blot, and a secondary, fixed pivot lug, adjacent to the pivot bolt. The other half has an opening in the pivot area with a recess on one side to hold the fixed pivot; the other side being arced about the recess and adjacent to, but just clearing the pivot lug. A spring on the other half holds the fixed pivot in the recess for basic opening and closing of the jaws of the pliers, but when the jaws engage a solid object, the fixed pivot comes out of its recess, and the pivot lug, which is toothed, engages the adjacent portion of the arced side of the opening, which is also toothed, to shift the fulcrum of the pliers from the fixed pivot on the one side of the opening to the pivot lug on the other side.

  • Patent number: 5020833
    Abstract: The accessory tool for anglers comprises two class 1 levers and a fulcrum between them. The levers are flat and rectangular, approximately twice as long as they are wide. They are pivoted on opposite sides of the fulcrum by stubs extending from the fulcrum through mating holes in the levers and held in place by an elastic band which also serves as a resilient element which biases one set of ends of the levers together. These ends are of uneven length so that one end rests against the other to form a pincer for holding ends of lines, leaders or the like. There are two hooks, one on each of these ends, which form an opening when the apparatus is at rest and the pincer closed. When the other ends are pressed together the tips of the hooks part, forming a gap in the opening and the pincer is opened.

  • Patent number: 4978140
    Abstract: A skate sail, to be held by hand, for propelling an individual on a mobile supportive device, such as skates or a skate board, has a central vertical brace, and a horizontal cross brace whose center is attached to the upper portion of the central vertical brace. Identical spars extend from the base of the central vertical brace past the ends of the horizontal cross brace to which they are secured. The edges of the cloth of the skate sail are secured to, and held tightly by the identical spars. The central, vertical brace may be secured to the central axis of the sail, and the ends of the horizontal cross brace can push the spars apart to keep the sail taut. The individual holds the rig at the intersection of the vertical and horizontal braces, which should be near the center of effort of the sail, in a suitable direction to cause any available wind to propel him on his skates or skate board in any of the possible desired direction.

  • Patent number: 4939787
    Abstract: A dummy load for a radio frequency transmitter uses a resistive liquid within a tube of non-conducting material as the load. The tube has grounded conductors at each end, and a centrally-located terminal that provides a load, with respect to ground, across two parallel branches. The output of the radio frequency transmitter is applied between the centrally-located terminal and ground. The ends of the tube are connected into a closed liquid loop that includes a temperature controlling system with a circulating pump, a heater for raising the temperature of the resistive liquid to a given, operating level, if necessary, and a heat exchanger for lowering the temperature of the resistive liquid to the given, operating level, when necessary; whereby the heat generated by the output of the transmitter can be dissipated, and the temperature of the resistive liquid, within the tube, kept at a constant mean temperature to provide a constant resistance under all load conditions.

  • Patent number: 4900094
    Abstract: A heavy vehicle has fixed cross braces mounted on its frame perpendicular to the direction of the vehicle, and close to the surface of a road. Movable cross braces fit within these fixed cross braces, and support a circular cutting tool that can be extended, laterally, to line up with a guide line on the surface of the road, and that pivots up and down to cut into the surface of the road. An additional pivot permits the circular cutting tool to be set level with the surface of the road before a cut is made. A water supply, with suitable nozzles directed at the cutting blades of the circular cutting tool, cools and lubricates the blades while they are cutting into the surface of the road. A source of compressed air with suitable nozzles, that can be directed at the newly cut holes in the surface of the road, cleans out the holes for the installation of safety reflectors.

  • Patent number: 4860682
    Abstract: A displacement hull is formed by making a series of cuts in a curves sheet or panel of semi-resilient material. At least one primary cut begins at one end of the panel, and extends in one direction for a substantial distance along the panel, but terminates within the panel. At least one primary cut in the other direction runs substantially-parallel to the primary cut in the one direction and overlaps it for a substantial length of the hull. The panel must have enough resilliency, and the cuts from opposing directions must be long enough to provide at least one, elongated, relatively-narrow, very-flexible strip, within which the panel develops from a flat surface, at the termination of each of the primary cuts, to any desired angle at the start of each cut. Secondary cuts, curving away from the primary cuts along the flexible strip, in either direction, can provide various cruves to the keel or chines.
