  • Patent number: 4459742
    Abstract: To increase the slot fill of armatures wound on a flier type armature winding machine of the type having inner and outer commutator shields, the outer shield is retracted during a portion of each winding cycle for each coil to permit the rotating fliers to draw the wires nearer to the armature shaft and thus deeper into the coil receiving slots. The inner shield, which has notches for exposing a pair of commutator hooks, is rotated to position the notches outside of the paths of the wire when the outer shield is retracted. A tamper assembly is provided for engaging the coil ends immediately after they are wound. The tamper assembly includes tamper rods slidably supported by the winding forms and also includes actuators for pushing the tamper rods into engagement with the coil ends. The tamper assembly may be operated after each winding cycle or only after selected winding cycles.

  • Patent number: 4457287
    Abstract: An archery bow assembly includes a bow, a hand grip, and a ball and socket joint establishing a universal connection between the hand grip and the bow. The ball and socket joint is mounted on the bow by a piston movable in a cylindrical cavity formed in a mounting block mounted to the bow. A bias spring acting on the piston causes key and slot members to firmly interfit with one another to prevent relative movement of the hand grip and the bow. The key and slot members are moved apart when the bow string is drawn to permit limited universal movement of the ball relative to the socket and, accordingly, the hand grip relative to the bow. Hydraulic fluid within the cavity and a valve associated with the piston dampen the return movement of the hand grip after the arrow is released. The location of the hand grip is adjustable in two dimensions to adapt to the style of grip of the archer.

  • Patent number: 4441501
    Abstract: The eyelet of a snap fastener conductor extends both through an adhesively coated supporting sheet and a gel pad whereupon a flange on the eyelet cooperates with the gel pad to form a cuplike cavity in which electrolyte gel is placed. The supporting sheet is formed from a substantially moisture and water vapor impervious material and cooperates with a cover that is also substantially moisture and water vapor impervious having a cavity receiving the gel pad to prevent gel dry out.

  • Patent number: 4380303
    Abstract: An essentially straight walled, minimally tapered or non-tapered container is provided with a radially outwardly projecting chime or bead formation which enables gripping of such container when molded to facilitate removal of the container from an injection mold apparatus. The described molded part extraction technology allows the formation of a novel easy-open closure in which the easy-openable closure structure is injection molded and may be one piece with a container side wall. The disclosure also includes a description of two forms of molding method and apparatus suitable for accomplishment of the described technology. The novel easy openable closure structure includes a closure panel forming a side wall which is inwardly convergent from one end of the container. A weakened web connects the closure panel to the container. The closure panel is provided with other weakened webs and a pull ring which enables removal of the closure panel by a pulling force exerted on the pull ring.

  • Patent number: 4370984
    Abstract: The signal conducting element of a medical electrode of the type bridged to skin by electrolyte and which is required to be X-ray transparent comprises a thin layer of a conductive paint adhered to a relatively thin supporting substrate, said substrate with adhered paint extending remotely from the electrolyte-to-skin interface for circuit connection and protected by a barrier which excludes electrolyte from the remote circuit connection.

  • Patent number: 4351355
    Abstract: A drain valve for use in a fuel tank and having a drain port and an axially movable poppet or valve member. The valve member has a first position for closing the port, a second position for opening the port to permit draining of liquid from the fuel tank, and a third position wherein the valve member is lowered to expose a seal thereon for inspection or replacement. A valve stem is connected to the valve member and has a pin with ends projecting therefrom. A retainer assembly comprised of two identical, interfitting retainer members has slots for receiving the ends of the pin and surfaces for supporting the pin and, in turn, the valve member when the valve is either opened or closed.

  • Patent number: 4319579
    Abstract: A medical electrode particularly suited for use as an EEG electrode comprises initially separated electrode conductor and electrolyte carrier components which are united prior to use of the electrode. The electrolyte carrier component comprises a disposable adhesive patch adhered to a disposable sponge member soaked with an electrolyte. The electrode conductor component comprises a reusable conductor ring having an affixed lead wire terminating with a plug-in device for effecting attachment to a monitoring instrument. Prior to use the electrolyte carrier components are stored in one or more evaporation resistant tray devices.

  • Patent number: 4312387
    Abstract: A starter motor field winding comprises an uninterruptedly continuous conductor edge wound to encircle a plurality of core elements. The core elements are on a mandrel to which the leading end of a length of strapping is secured. The mandrel is rotated about a first axis to locate successive core elements in position to have coils wound therearound and rotated about a second axis to edge wind the strapping into coils about the core elements.

  • Patent number: 4291813
    Abstract: A reusable closure for a container has a reversibly hinged annular pilferproof band integrally joined thereto by a relatively thin annular web serving as a hinge. When the parts are assembled, the band is pivoted about the web from a first position to a second, reversed position wherein it extends over a bead on the container. In the illustrated embodiments, the closure is a screw cap for a bottle and the band is joined about the base of the skirt of the cap. The bottle has a threaded neck for receiving the screw cap and the aforementioned bead about the neck. The band loosely interfits with the bead so that the cap can be initially unscrewed for removal without substantial restriction. As removal continues, the band so engages the bead that the connection between the band and the closure skirt stretches and then ruptures. Apparatus and methods for reversing the positions of a band are also disclosed.

  • Patent number: 4290552
    Abstract: For use in a ventilation flue or the like, a damper positioning mechanism comprising a yieldable means biasing said damper toward a first position, motive means for opposing the bias of said yieldable means to drive said damper to a second position and thermally responsive means modulating the return of said damper from said second position to said first position, said thermally responsive means being strong in relation to said yieldable means. In one embodiment the thermally responsive means resists closure of said damper until exposed to a sufficiently low temperature. In another embodiment the thermally responsive means resists opening of said damper until exposed to a sufficiently high temperature.

  • Patent number: RE31112
    Abstract: In the present invention, an automatic flue damper located in the vent stack of a household furnace or other apparatus requiring venting is interfaced with a thermostatic control and a fuel supply valve associated with the apparatus so as to maintain a vent passage to the atmosphere normally open during times when combustion is occurring in the apparatus and to close the vent passage at an appropriate time following the termination of combustion in the apparatus. The normally open vent condition is maintained by a damper positioning spring. Vent closure following combustion is accomplished by means of a direct current solenoid. Further included in the interfacing circuitry are a temperature sensing device effective to disable the solenoid, thus opening the vent, upon the appearance of unsafe stack temperatures and a pressure sensor which also disables the solenoid to open the vent stack upon the occurrence of an inappropriate discharge of fuel to the combustion chamber.
