  • Patent number: 5398339
    Abstract: A shoulder pad assembly for contact sports such as hockey is described. Two separate shoulder assemblies, in the form of generally U-shaped shoulder bands, are each pivotally connected fore and aft to chest and back pieces. Preferably the pivotal connections are co-axial, so that there are just two pivot points, namely fore and aft pivot points centrally located on the chest and back pieces, thus generally defining a V-shape for the shoulder portions of the pad. Preferably, the flexibility is limited by the use of a pivot clip at each pivot point, the pivot clip having at least one post disposed from the pivot axis and projecting from the clip through an arcuate slot in each shoulder band, the arcuate slots being of finite length such that further pivoting is prevented once the post reaches an end of the slot.

  • Patent number: 5375269
    Abstract: The water-saving devices for a toilet is of the type which float up and down on the overflow tube, where downward movement of the device brings it into contact with the flapper valve at the bottom of the toilet tank in order to close it prematurely, thereby reducing the amount of water used for the flush. Upper and lower opposing cup shapes are integrally mounted around respective cylindrical sleeves, the sleeves being adapted to slide one within the other to adjust the spacing between the opposing cup shapes. One sleeve has an inset area with a longitudinal row of spaced holes or indentations. The other sleeve has an elongated tongue having a raised dimple which engages one of the spaced holes or indentations to set the spacing between cup shapes. A number of ribs or vanes are molded as part of the upper cup, and act to deflect the float rod to reduce any possibility of the float rod catching under the upper cup.

  • Patent number: 5372142
    Abstract: The invention provides a cochlear response audiometer, and new methods for signal generation, detection and processing. The invention preferably uses bone conducted sound, applied to the mastoid, forehead, or any other place with good mechanical contact to the skull, via a vibrator. The bone conducted sound stimulates the cochlea via the skull. The stimulus also produces a sound in the ear canal, but at a very low level, so there is no high level stimulus signal and ringing travelling toward the cochlea at the same time as the cochlear response is travelling back into the ear canal. The responses from the cochlea are recorded, preferably by using a differential amplifier input circuit for the microphone when air-borne response signals are used, and the responses are processed in a way which compensates for the stimulus artefact, by subtracting a scaled-down version of the cochlear response to a large stimulus from the cochlear response to a moderate stimulus.

  • Patent number: 5366098
    Abstract: An archery bow hanger is capable of holding a bow or bows vertically and in parallel spaced relation to a door or wall on which the hanger is mounted. A mounting means may take the form of a U-shaped hook member which extends around the top edge of a door. The hook member is sufficiently thin that, when the door is closed, the hook member is able to sit between the door and its adjacent frame. The hook member is connected to one end of an extension member that extends away from the door, and a horizontal bar is connected to the other end of the extension member. A bow is held on the horizontal bar such that its respective limb and string extend on opposite sides of the bar. Several alternate mounting means are described. The hanger allows a bow to be vertically mounted such that the limb of the bow is directed away from the door or wall on which the hanger is mounted, adjustments to the bow being thereby facilitated.

  • Patent number: 5365688
    Abstract: A fish gaff apparatus has a hook member and a pole member. The hook member has a nook portion and a cover portion that is biased to assume different positions relative to the hook portion. The cover portion in a first position extends between both ends of the hook portion to prevent injury by the hook end of the latter. The cover portion in a second position holds the hook member on the pole member. Using the pole member, the hook member is inserted into a fish. The pole member is then moved relative to the hook member to disconnect those two members, and the bias between the two portions of the hook member moves the cover portion back toward its first position to press against the fish. The hook member may be constructed from a single length of wire.

  • Patent number: 5355782
    Abstract: The smoke generator produces smoke from combustible matter, such as sawdust or particulated wood, under a controlled set of smoke generation parameters which can be varied over a range of operating set-points. The pyrolysis and partial combustion phases of smoke generation are physically separated and are independently controlled. A controlled rate of sawdust or other combustible matter is fed into an air-excluded pyrolysis chamber in which the pyrolysis temperature is controlled by means of an adjustable power supply to a heating element in the pyrolysis chamber. The ash remaining after pyrolysis of the combustible matter is continuously removed from the pyrolysis chamber. Pyrolytic gases generated by thermal destruction of combustible matter in the pyrolysis chamber are removed to a second chamber where a controlled rate of air is injected with the hot pyrolytic gases to achieve a desired level of partial combustion.

  • Patent number: 5356648
    Abstract: A frozen dessert such as ice cream, and a process for manufacturing same, are described. The chocolate or other flavoring composition is injected into the stream of semi-frozen dessert in the form of a pumpable semi-liquid which freezes into ribbons or strands upon contact with the dessert. The fat and oil fractions of the flavoring composition are formulated so that the composition can be conditioned from a solid or semi-solid paste into a high-viscosity semi-liquid composition which can be pumped with a positive-delivery pump, and so that as soon as the composition is cooled a few degrees by being in direct contact with the ice cream, the viscosity rises rapidly and the composition once again becomes a solid or semi-solid. The conditioning can be accomplished in one of at least two ways. Firstly, the flavoring composition can be conditioned from the temperature at which is is a semi-solid paste, to a few degrees above that temperature.
