  • Patent number: 5151000
    Abstract: A hopper containing fuel pellets for a stove opens downward into a feed trough which extends generally horizontally toward the firebox of the stove. A feed plate is positioned such that pellets from the hopper are supported on the feed plate. The feed plate is reciprocated between a rearward position adjacent to the hopper and a forward position adjacent to the firebox so as to advance pellets toward the firebox. A gate member is mounted adjacent to the end of the feed trough remote from the hopper. The gate member is positioned to be engaged by the feed plate when the feed plate is in its forward position so as to close the feed trough and hopper from the firebox. The mechanism for reciprocating the feed plate normally maintains it in its forward position in which the feed trough and hopper are isolated from the firebox.

  • Patent number: 5117892
    Abstract: Channels having inward-opening grooves are mounted on the upright facing sides of a window frame below the roller of a conventional roll shade. Elongated sealing strips of resilient sheet material have their opposite edge portions rolled or folded inward into abutting relationship and are inserted into the channels. The opposite edge portions of each strip are biased together due to the inherent resiliency of the strip sheet material. The channels and strips capture the side margins of the body of the roll shade to seal the shade to the window frame.

  • Patent number: 5088498
    Abstract: Quadrature phase signals (I and Q) from a pulsed Doppler medical instrument are analyzed to detect phase changes of consecutive echoes from tissue at a depth of interest. Such phase changes are analyzed to determine tissue displacement. Relative displacements at different depths are examined to detect tissue expansion and contraction. The area of the uterus of a pregnant female can be scanned and the frequency of tissue displacement or expansion and contraction examined to determine pulsations due to blood supplied by the fetal heart and/or pulsations due to blood supplied by the maternal heart. Conventional M-mode or B-mode images can be colorized differently for different frequencies of tissue displacement.

  • Patent number: 5083076
    Abstract: A wheeled cabinet contains two internal booster batteries. Jumper cables are connectible to the booster batteries by a plug-and-socket connector. With the plug disconnected from the socket, end clamps of the jumper cables are applied across a battery or batteries of a vehicle to be jump started. Display lamps are actuated to indicate whether or not the polarity of the jumper cables as connected to the vehicle battery or batteries is correct and whether or not the connection points are appropriate for the potential (12 volt or 24 volt) which should be applied. When it is determined that the connection of the jumper cables to the vehicle batteries is correct, the plug is inserted into the socket to connect the booster batteries to the vehicle battery or batteries and permit jump-starting of the vehicle.

  • Patent number: 5076757
    Abstract: The rotary drive shaft of a centrifugal pump extends vertically through a cylindrical housing and into a casing defining a bowl for the impeller of the pump. A mechanical seal and bearings for the drive shaft are positioned between the pump bowl and the interior of the housing which forms a reservoir for liquid lubricant. The impeller includes a radial shroud plate, a first set of pumping blades projecting downward from the shroud plate toward the axial pump inlet and a second set of blades or vanes projecting upward from the shroud plate. The upper vanes result in slight suction being generated in the area of the seal tending to draw lubricant from the housing reservoir through the bearings and seal. Seal failure is detected by a rapid decrease in the level of lubricant in the reservoir.

  • Patent number: 5070548
    Abstract: A buoyant block of rigid material is positioned beneath the float of a water supply valve in the toilet tank of a flush toilet so as to maintain the float a predetermined level above the surface of water in the tank. The float determines the level to which the tank is refilled following flushing of the toilet. Consequently, after flushing, the tank is refilled to a lower level than it otherwise would be if the block were removed, and at the next flush a lesser quantity of water is discharged from the tank to the toilet bowl for conserving the amount of water used by the flush toilet.

  • Patent number: 5070526
    Abstract: An analog communication signal such as the signal transmitted over a telephone line is converted to digital form for storage in the memory of a computer. Segments of the digital representation of the signal are analyzed to determine whether or not the signal has uniform frequency components repeating at regular intervals. Detection of such regularly repeating uniform frequency components is useful in an automated telephone system to determine whether a telephone signal consists of voice or a call progress signal.

  • Patent number: 5066213
    Abstract: A mold-forming cup has a frustoconical interior tapering in cross-sectional size from the top of the cup to the bottom. A metal master model is mounted generally centrally of the interior of the cup, whereupon the cup is packed with rubber mold material. The mold material is vulcanized and the resulting mold is cut into top and bottom sections such that the master model can be removed. The mold sections are placed back together and inserted into a retaining ring having a frustoconical interior of a size slightly smaller than the size of the interior of the mold-forming cup to accommodate for shrinkage of the mold during vulcanization. The mold is held in the retaining ring under pressure so as to be restrained on all sides during injection of wax into the central cavity of the mold to form a wax pattern of the same shape as the master model.
