  • Patent number: 5000609
    Abstract: An improved device for quickly and reliably retaining a pair of bearing cups on a universal joint cross during purging and shipment thereof is disclosed. The retainer includes a central portion which is generally elongated and flat in shape. In a first embodiment, first angled portions are formed integrally with each end of the central portion extending outwardly therefrom. The first angled portions may be oriented at relatively small angles with respect to the central portion. Second angled portions are formed integrally with each end of the first angled portions extending outwardly therefrom. The second angled portions may be oriented at relatively large angles with respect to the first angle portions. The corners between the first and second angled portions are adapted to receive the outer edges of the bearing cups therein. Respective apertures are formed through the retainer at each of such corners to receive locating tangs formed on a mating yoke for the cross.

  • Patent number: 4976731
    Abstract: Highly satisfactory orbital implants comprising granular hydroxyapatite and spheres of porous, low density hydroxyapatite are described. The implants are useful in enucleation and evisceration procedures. In enucleation procedures, the implants can be sutured to the eye muscles by either insertion in a scleral sac or other suitable container or, in the cast of spherical hydroxyapatite, sutured to the eye muscles by means of holes in the spheres. After healing, the implant is drilled to receive a peg for fixing an artificial eye to the implant to complete the prosthesis.

  • Patent number: 4945347
    Abstract: A motion and orientation responsive device having a pendulum pivotally mounted between its ends, and means for detecting relative displacement of the upper pendulum end and a zero position reference on the pendulum support from certain normal relative positions thereof in response to either or both translational and rotational displacements of the device. Presently preferred embodiments of the invention are a seismic or earthquake alarm, an intrusion alarm, and a tilt alarm. In these preferred embodiments, the pendulum shaft is a slender resilient wire, and its pivot is situated close to its lower center of mass in order to amplify the lateral motion of the upper pendulum end for a given angle of pendulum rotation and thereby enhance the sensitivity of the device to low magnitude displacements.

  • Patent number: 4930178
    Abstract: A compact, self-contained recycling extraction cleaner having a body member wherein a handle half of the body has all of the electrical components, except possibly the cleaning fluid pump, sealed therein, and the cleaning fluid is retained within a removable discharge head half of the body that defines a plenum chamber and carries a spray nozzle, filter and vacuum intake head, as well as, perhaps, the cleaning fluid pump. Furthermore, in accordance with another feature, solution conduits to and from the pump may be built into the wall of the body in a manner that, when the cleaning fluid pump is located in the handle half, the conduit portions of the two halves sealingly mate in the assembled condition of the body halves. Still further, arrangements are provided for preventing cleaning solution from being discharged through the vacuum intake head or flowing into the vacuum blower.

  • Patent number: 4918786
    Abstract: A hinge having at least three leaves pivotally joined along edges of the leaves and adapted for attachment to two members to be pivotally connected with at least one member secured to a pair of the leaves which are mutally inclined in such a way that each leaf of the pair resists bending of the other leaf of the pair. A present best mode embodiment of the hinge has four leaves and is designed primarily for use on so-called ultralight airplanes as aileron, rudder, and elevator hinges which are immune to fatigue stress failure. Another hinge embodiment is designed for use as a door hinge and has only three leaves.

  • Patent number: 4858563
    Abstract: An apparatus for cleaning a residential water heater 10 or the like. The water heater is generally vertically disposed and has a cylindrical side wall 12, a top 14, and a bottom 16. A water supply tube 20 terminates in a nozzle 22 which permits entry of a stream of water 24 in a generally horizontal spray pattern along the bottom to flush and agitate any foreign matter 38 along the bottom. A drain cock 28 is provided within the heater side wall and opposite the nozzle, the drain cock being opened upon flushing of the bottom of the water heater so that any foreign matter is removed through the drain cock. In lieu of a simple, single-orificed nozzle, a multiple-orificed nozzle 22b or a plurality of nozzles may be provided.

  • Patent number: 4835071
    Abstract: An electrode having higher power output is formed of a thin, porous film (less than 1 micrometer) applied to a beta-alumina solid electrolyte (BASE). The electrode includes an open grid, current collector such as a series of thin, parallel, grid lines applied to the thin film and a plurality of cross-members such as loop of metal wire surrounding the BASE tube. The loops are electrically connected by a bus wire. The overall impedance of the electrode considering both the contributions from the bulk BASE and the porous electrode BASE interface is low, about 0.5 OHM/cm.sup.2 and power densities of over 0.3 watt/cm.sup.2 for extended periods.

  • Patent number: 4829706
    Abstract: Readily portable apparatus for exterminating animal pests, particularly rodents such as gophers which burrow through the ground. The apparatus includes a small, lightweight internal combustion engine, and means for directing the engine exhaust into exterminating relationship to the pests, such as into a burrow or tunnel of a ground burrowing rodent. The preferred engine is a two-cycle engine which burns a fuel/oil mixture to produce exhaust containing smoke which asphyxiates, carbon monoxide which effectively poisons, and intense pressure pulsations which tend to drive a rodent from an underground tunnel, such that the rodent faces the delema of remaining underground and dying from the effects of the exhaust gas or coming to the surface and exposing himself to death in other ways above ground. In the presently preferred apparatus, the engine is mounted on an inverted bowl-shaped exhaust shroud which seats on the ground to direct the engine exhaust into an underground rodent burrow.

  • Patent number: 4802813
    Abstract: An elongated metal apparatus which comprises at least one longitudinal gripping member and preferably a pair of longitudinal gripping members in spaced apart relationship, which are anchored to a slab of concrete and can be used in conjunction with a forklift to physically lift and move the slab of concrete to another location to thereby expose the area beneath the concrete. The apparatus enables a user to remove a section of concrete without the necessity of breaking up and discarding the section of concrete and having to subsequently re-pour the concrete. The apparatus includes a central tunnel or channel for receiving a fork of a forklift, a pair of side members which permit the apparatus to be affixed to the concrete using anchor bolts, and a pair of covering members which cover the area of the anchor bolts to prevent then from flying out and injuring someone if one or more of the anchor bolts should shear loose during the lifting or moving process.
