  • Patent number: 6758318
    Abstract: A continuously moving sidewalk pedestrian transport system includes a railway loop having a pair of continuous parallel rails connected by a plurality of elongated tie rods disposed upon a ground surface. An area defined between the pair of rails and ground surface is hydraulically sealed to prevent fluid placed between the rails from escaping. A pedestrian pathway is mounted on top of the rails to contain the fluid under pressure. The pedestrian pathway is mounted such that it can move along the railway loop. A pedestrian walking upright can step onto the moving pathway and be transported along the railway loop. When the pedestrian reaches a desired location along the loop she may step off of the moving pathway to continue walking to her desired location.

  • Patent number: 6755814
    Abstract: The invention relates to an implantable infusion pump comprising a housing, a base plate, a propellant chamber, a bellows having an internal volume for receiving a medicament to be administered to a patient, a constriction segment leading to a catheter placed in the body of the patient and communicating with the bellows internal volume, a resonant circuit formed by a coil, and a capacitor detecting the distance between a bottom surface of the bellows and the base plate. The coil is mounted on or in a bottom surface of the base plate and pointing towards the bellows bottom surface such that an inductance of the coil and a resonant frequency of the resonant circuit is a function of the distance between the bellows bottom surface the base plate.

  • Patent number: 6742557
    Abstract: An annular pan for mounting over a drum lid containing a liquid, the drum top having a hole for a pump conduit and an air hole. The annular pan has multiple parallel elongated walls increasing in height from the pump conduit to a portion of the pan containing a drain hole axially aligned with the drum lid air hole. The drain hole is covered by a device having a slot into which a fine mesh filter can be inserted for catching debris in liquid. A raised edge of the pan above a top surface of the pan has an indentation for receipt of the pump conduit.

  • Patent number: 6731250
    Abstract: A bottom bracket is attached to a vertical wall below a window inside a room. A top bracket joins a longitudinal housing to the bottom bracket. The longitudinal housing encloses multiple telescoping side rails for extending a top support plate outwardly from the housing to a position outside an open window. An upper surface of the top support plate is attached to a satellite TV dish base plate.

  • Patent number: 6723002
    Abstract: A golf putter has a flat ball-striking surface at a right angle from a top and bottom surface of the main blade. The top surface has an irregular back edge and a straight front edge interfacing with the ball-striking surface. The bottom surface extends beyond the back edge of the top surface in a semi-circular pattern and also has a straight front edge interfacing with the ball-striking surface. A shaft penetrates the top surface at a left portion looking from the ball-striking surface. The shaft is bent at a distance of one to four inches above the top surface of the blade and the bend is ten to twenty degrees toward the blade top surface.

  • Patent number: 6709403
    Abstract: A top and bottom housing joined together have a patient port and ventilation port in axial alignment. The top housing contains dry indicator paper for changing color in response to the presence of CO2. In addition, a shaft having a pointer on a top portion rotates in response to air in the housing to indicate pressure. A helical outer wall of the shaft engages a notch in a hollow stem attached to a membrane in the lower housing so the shaft rotates in response to air pressure on the membrane.

  • Patent number: 6709304
    Abstract: A spot marking buoy. A flotation body, cylindrical in shape with rounded ends having a groove around the periphery of the flotation body creating a reel with one end of a string attached to the reel and the other end of the string attached to an anchor weight. The flotation body employs angular cores to receive a rubber locking cord which is affixed to the flotation body by the use of crimps or knots on the ends of the rubber locking cord with said crimps or knots being larger in circumference than the angular cores. And surface grooves on each side of the top end of the flotation body to receive and secure the rubber locking cord when in use and when storage. Included are recessed counterweights, an anchor weight and anchor weight housing for storage and a built in hand grip for reminding.

  • Patent number: 6696655
    Abstract: The invention relates to a device and a method for blowing out metal fractions from a stream of bulk material that is conveyed by bulk material means. The device comprises blow-out nozzles which are located on a drop section, and which are arranged along a width-wise extension of the stream of bulk material, for blowing against individual particles of bulk material in order to modify the trajectory in such a way as to produce a second sub-stream that branches off. The blow-out nozzles can be controlled according to the sensor coil scanning results relating to the bulk material particles. A plurality of sensor coils is provided underneath an essentially horizontal section of the stream of bulk material in the form of an LC oscillating circuit. Said sensor coils are provided for detecting the eddy currents that are induced. Optoelectronic means are also provided for determining the blow-out position and for determining the location of each of the particles of bulk material.

  • Patent number: 6692775
    Abstract: A gel formulation is combined with a bactericidal concentrate which is a liquid mixture of about 1000 parts by volume of ultra pure water having an electrical resistance of 16-26 megohms, total dissolved solids of less than 0.04 parts per million and a specific conductance of less than 0.10 mho with about 1.2 to 3 parts by volume of Willard Water as prepared in accordance with U.S. Pat. No. 3,893,943. The bactericidal liquid concentrate in the amount of 3.5 to 12 ml in one liter of gel formulation is applied directly to a skin surface area having a burn or other dermal lesion to protect the area from bacterial contamination.

  • Patent number: 6672971
    Abstract: Multiple molded polymeric units are joined together by side mounted fastening mechanisms. Each polymeric unit is molded as an integral structure with a smooth contoured top surface and a bottom grid like portion. Each polymeric unit has two side walls containing slots for mounting the fastening mechanism. A third side wall joining the two walls is a raised rolled edge higher than the top surface. The polymeric unit has a receptacle for receipt of a golf cup and a water drain hole. A simulated grass layer overlays the smooth top surface of the joined polymeric units.
