The outer surfaces of the dielectric chips are metalized and have a roughened or coarse finish to provide contact between the dielectric chips and the conductive plates, thereby permitting use of nonconductive adhesive to bond the parts of the assembly together.

Abstract: A torque wrench is presented having a pair of clutches in series. One clutch is a one way clutch, preferably reversible, which transmits the input force in one direction during torquing operations; and the second clutch provides friction restraint against movement in the opposite direction. When desired, force applied to the wrench in the opposite direction overcomes the friction clutches to release the wrench from the work.

Abstract: An electrical discharge is controlled in such a manner as to permit its use to reliably ignite a fuel stream consisting of pulverized coal entrained in air. The ignition technique of the present invention creates expanding and contracting plasma pockets at a rate which is high compared to the velocity of the fuel stream and permits the ignition of the fuel stream in a cold furnace and/or without supplemental combustion of liquid or gaseous hydrocarbon fuels.

Abstract: A mounting bracket for use in mounting quick connect circuit blocks to a wall or pipe comprising a pair of flanges for attachment of the bracket to the wall, a block supporting beam for supporting the circuit block, the block supporting beam being parallel to and spaced from the flanges by connecting webs. A pair of dowel-like protrusions project from the center of the beam and provide a fixed point about which the terminal block can be suspended and allowed to pendulate and come to rest in a vertical position. A method of mounting the bracket is disclosed wherein a first bracket is leveled and mounted on a wall, a second bracket is affixed to a first circuit block, and the first circuit block is suspended from one of the dowel-like protrusions and allowed to pendulate and to come to rest in a vertical position. The circuit block is then affixed to the first bracket and the second bracket is affixed to the wall.

Abstract: A spinning rotor for use in an open end spinning device for producing twisted yarns, the spinning rotor being symmetrical about a longitudinal axis and comprising a body machined from a unitary piece of self-lubricating plastic. The body includes a peripheral wall which defines an exterior surface which is cylindrical with respect to the longitudinal axis of the rotor. A reinforcing rim having the shape of a right circular cylinder and defining an internal cylindrical wall is positioned in abutment with the cylindrical exterior surface of the peripheral wall to reduce deformation of the body when the body is subjected to centrifugal forces.

Abstract: A thermodilution injector is presented in which a pneumatically powered piston operates the plunger of a syringe to deliver a measured amount of injectate in an accurately predetermined time period.

Abstract: A thermoelectric energy system comprising first and second separated metal electrodes, an electrolyte comprising a source of metal ions and a material for complexing the metal ions to form a metal ion complex, the electrolyte being disposed between and in contact with the electrodes to provide a metal ion conduction path which extends substantially the entire distance between the electrodes. A temperature gradient is imposed between the electrodes to produce a voltage across the electrodes. An electric circuit is connected to the electrodes to allow for removal of electrical energy from the system.

Abstract: A thermally responsive electric switch for protecting electric motors comprises two sheet metal switch terminal members, one switch member having ear portions deformed around the other switch member to secure the switch members together. An intervening strip of insulation maintains electrical isolation between the two switch members and may be impregnated with adhesive to bond the switch members. One switch member mounts a thermally responsive bimetallic actuator carrying a movable contact and the other mounts a fixed contact. The fixed contact projects through an aperture in the insulation, such aperture registering with an aperture in the switch member carrying the movable electrical contact so that the electrical contacts engage by way of the registering apertures; thus the contacts are disposed in a protected position. Interengaging recesses and dimples may be provided in the switch members to prevent relative rotation therebetween.

Abstract: A brush guide for guiding a brush to provide for the painting of a continuous line, the brush guide comprising an elongated body including a continuous edge and at least two support legs extending from the body, each leg defining a flat base portion, the legs defining an elongated space therebetween, the base portion of the legs being offset from a vertical projection of the edge to accommodate the brush during painting.

Abstract: A hair dryer comprising a generally tubular housing including twogenerally semi-cylindrical grip parts having edges including complimentary grooves and projections which engage each other to secure the grip parts together, the housing accommodating a heating device, a motor and an air transport device therein, a first end grid which is mounted over an intake opening on one end of the housing to secure the grip parts to the first grid as well as to each other, and a second end grid mounted over an exhaust opening at the other end of the housing to secure the semi-cylindrical grip parts to the second grid as well as to each other.

Abstract: Liquid level indicating floats which may be used, for example, to measure the level of gasoline in a fuel tank or to monitor the flow of fuel through a carburetor. In one embodiment, the float comprises a generally cylindrical body portion which terminates in an outwardly protruding cylindrical ledge having an upper surface and a lower surface, the ledge having a predetermined thickness. A supporting arm is provided which includes a loop which engages the lower surface and an elongated end portion extending from the loop which engages the upper surface of the ledge to secure the supporting arm of the float. In another embodiment of the invention, the float comprises a cylindrical body portion having two chordal grooves cut therein to allow for insertion of a loop having linear portions, the linear portions adapted to engage the chordal grooves.

Abstract: A sealing ring assembly particularly well suited for use in concrete pipes through which a liquid is flowed includes a gasket ring and a locking ring which cooperates therewith. The gasket ring is comprised of a resilient material and defines a recess which receives a plastic locking ring which is preferabbly formed by injection molding.

Abstract: An apparatus and method for treatment of fluid such as water with ozone. The apparatus comprises an ozonator for providing a gas containing ozone and an aspirator which mixes the gas with water to provide an ozone and water mixture having microbubbles of gas therein. The mixture is then circulated through an elongated treatment conduit having a length of between about 20 and about 40 feet and a diameter less than about 1 inch to allow the gaseous ozone to dissolve in the water. Throughout the length of the conduit the ozone oxidizes impurities in the water and provides water having a relatively high purity. In the method of the present invention a liquid such as water is mixed with ozone and the mixture is then circulated through an elongated treatment conduit to allow for dissolution of the ozone into the water and to provide purified water. The ozonator used to provide ozone is capable of providing a gas having at least about 1.

Abstract: A feather valve is presented having shock absorbing strips in the guard section to absorb impact loads and dampen vibration of the feather strips.

Abstract: Related multiple characteristics of a single complex waveform are displayed as a variable length line of light with a floating spot which moves relative to the line. Logic circuitry, in response to an electrical input signal, causes energization of a plurality of the light emitters in response to the first input signal characteristic and the energization or extinguishing of a single light emitter in response to a second characteristic of the input signal.
