  • Patent number: 5050692
    Abstract: A method for directional drilling of a well with a motor and drill bit. A tubular housing is secured to the lower end of the motor with the housing having a first surface with an axis angularly disposed relative to the axis of the tubular housing. A second tubular housing has a surface engagable with the first surface and is angularly disposed relative to the axis of the second tubular housing with the extent of the engagement of the first and second surfaces determining the angular position of the axis of the second tubular housing relative to the axis of the first tubular housing. The extent of the engagment of the surfaces is selectively adjustable by shims. A first angular stabilizer is carried with a drill bit which is rotatably mounted with a drive means including universal joints. The apparatus is secured to a tubing string with a drill bit and lowered into the bore hole with the apparatus actuated by application of tubing weight with direction being controlled by rotation of the drill string.

  • Patent number: 4982866
    Abstract: A bi-stable hinge unit (10) of elastic material connects two inflexible end portions (12, 13) to take up two stable positions on either side of an intermediate unstable position. The hinge unit (10) comprises two equal elements (14, 15), each of which having two cantilever arms (18, 20), linked to each other by two folding lines (22) acting as a "living" hinge. A triangular rigid plate (16) is arranged between and defined by said folding lines (22). The elements (14, 15) are arranged substantially parallel to each other with a distance therebetween and forming the main hinge line between said end portions (12, 13). By swinging the end portions (12, 13) toward each other along the main hinge line, the four cantilever arms (18, 20) will start to deflect and act as springs and the two triangular plates (16) will rotate through approximately in a plane normal to the elements (14, 15).

  • Patent number: 4974579
    Abstract: An induced draft, fuel-fired upflow furnace is provided with a compact, high efficiency heat exchanger having horizontally spaced apart inlet and outlet manifold structures which are innerconnected by a horizontally spaced series of vertically serpentined, relatively small diameter flow transfer tubes. Larger diameter inlet flow tubes are positioned beneath the balance of the heat exchanger, extend parallel to the transfer tubes, and have upturned discharge ends connected to the underside of the inlet manifold. The heat exchanger is configured so that its total vertically facing peripheral surface area is considerably larger than its total horizontally facing peripheral surface area, thereby significantly reducing undesirable outward heat loss through the vertically extending furnace housing side walls upon burner shut off and increasing the overall efficiency rating of the furnace.

  • Patent number: 4974631
    Abstract: A dome pressure maintaining valve and circuit for maintaining dome fluid pressure in a pilot operated relief valve is presented wherein the dome pressure in the relief valve is prevented from dropping below a preset value even when inlet pressure at the relief valve drops to zero. The dome pressure maintaining valve incorporates a compact check valve and a back flow relief valve with the two components integrated into one piston embodiment, the valve having in communication with a body bore inlet and an outlet. The circuit provides inlet fluid flow in communication with a piston valve chamber through a passage from the inlet port through the piston under the poppet check valve and through multiport and exterior piston valve ring groove means to the outlet port when the inlet fluid pressure is greater than the outlet fluid pressure.

  • Patent number: 4975245
    Abstract: A recirculating high velocity hot air sterilization device includes a housing having a chamber therein. A corrugated, perforated jet curtain plate is disposed within the chamber and partially defines an air supply plenum positioned outwardly of the chamber, the plenum having an electric heating element operatively positioned therein. Spaced apart from the jet curtain plate within the chamber is a nonperforated deflector plate which extends parallel to the jet curtain plate and may be of a flat or corrugated configuration. A blower is connected to the housing and creates therein a recirculating flow of heated air which sequentially flows into the air supply plenum across the heating element, outwardly in a forward direction through the perforations in the jet curtain plate and into the housing chamber, back into the blower, and then into the air supply plenum.

  • Patent number: 4972824
    Abstract: Various representative commericial cooking devices are disclosed wherein a recirculating flow of heated air, at a food cooking temperature, is created within a housing in which a horizontally disposed food support and cooking member, such as a perforated metal plate, a solid griddle plate or a metal broiling grate, is positioned. A plenum structure is utilized to convert a portion of the continuously recirculated air into a spaced series of relatively high velocity heated air impingement jets which are caused to laterally diffuse and at least slightly overlap prior to striking at least one side surface of the food support structure. In this manner, each food support structure side surface subjected to such diffused jet impingment is evenly blanketed with heating air to thereby very uniformly transfer heat from the air to the food support structure, and thus to the food supported thereby, at an accelerated rate.

  • Patent number: RE33562
    Abstract: A composition useful, inter alia, as a fuel, is based on ethyl alcohol denatured with methylisobutyl alcohol and kerosene, which is mixed with xylenes and isopropyl alcohol. The xylenes and isopropyl alcohol act with the denaturizing agents to raise the flash point above that of ethyl alcohol alone and also to mask the odor and color the flame, thus making the composition safer for use as a charcoal lighter or as a fuel for e.g. patio lamps.
