Abstract: TITLE:        ELECTRICAL CABLE CONNECTOR WITH CAM LOCK    INVENTORS:    Arthur I. Appleton, Jon L. Liljuquist and Carlos J. Ylagan ABSTRACT OF THE DISCLOSURE      An electrical cable connector for use in a knockout opening of an electrical box or the like includes a cam element with a slot therein arranged to receive the tip of a screwdriver transverse of its rotational axis so as to permit the application of a significant torque on the cam with a minimal force to thereby securely wedge the cable in the connector body and prevent its removal.  This [elec-trical] connector features a tubular body with an enlarged inner end to permit its installation into a knockout open-ing from the inside of the box, an integrally molded pres-sure pad opposite the cam element to permit the connector to accommodate several sizes of cable, and snap locks de-signed to defeatably hold the cam element selectively either in its open or its locked positions.

Abstract: ABSTRACT       A wooden structural beam composed of two opposi-tely shaped halves joined together to form the web portion, and the envelope, of the flange portion of the beam. Each beam half is molded from very thin wooden laminations bonded together and shaped to define a flat, vertical central panel, with diagonal panels extending upwardly and downwardly from the upper and lower edge portions of the central panel and trans-versely outwardly in a direction opposite the vertical line of symmetry of the beam. Each beam half also includes vertically disposed flange panels which extend upwardly and downwardly from their corresponding diagonal panels to lie in a plane parallel to, and transversely offset from, the plane of the central panel. The upper flange panels of the two beam halves define an upwardly open trough for snugly receiving a rectangularly shaped chord member therebetween. Correspondingly, the lower flange panels of the two beam halves define a downwardly open trough for snugly receiving a rectangularly shaped lower chord member therebetween. Constructed in this manner, the beam is pleasing enough in appearance to be left exposed to the interior of a dwelling, office or similar structure.

Abstract: ELECTRONIC-MAGNETIC CURRENT ISOLATOR CIRCUIT      ABSTRACT OF THE DISCLOSURE             Disclosed is a circuit for providing an electrical output signal proportional to but electrically isolated from a current flowing in a power circuit, and more particularly, to the current supplied to the field or armature winding of a DC motor load which receives power from a rectifier circuit coupled to an AC power source. The circuit includes a transformer including at least two winding, a primary and a secondary, wound on a saturable core. The primary winding is coupled to the power circuit, whereas the secondary winding is coupled to an output circuit along with control circuit means which are adapted to keep the core out of saturation in response to a power current flowing in the primary winding which by itself is adapted to drive the core into saturation.  Accordingly, the time the core is not in saturation an output current flows in the secondary winding, which is related to the primary current by the turns ratio of the transformer.

Abstract: A B S T R A C T .          Improved process and device for extracting energy present in a flowing fluid medium wherein a supported hub with propellers or blades is placed in said medium and the blades are provided with a wing or vane at the tip. The wing is of such a form that it generates a "venturi effect" in the flowing medium by which a part of the fluid which should normally pass outside the propeller disc area, is drawn into the propeller. The improvement consists of mixing of fluid which normally should pass outside the venturi with fluid which has flowed through the blades by provisions on blades and/ or wing or vanes.

Abstract: ABSTRACT There is provided an evaporation installation with a system for recirculating and re-using heat. The heat available in the exhaust vapour is partly transformed into useful heat at a higher temperature, without requiring any significant use of more expensive process steam.  The recaptured heat is directed back to the evaporation process itself or to some other process. More particularly, the exhaust vapour from the installation is led directly to an absorber which containers a multi-component mixture that absorbs the vapour completely in an exothermic manner.  In a preferred embodiment, the heat of absorption thus generated is utilized to produce process steam, which is directed back to one or more of the evaporation stages of the installation itself, or to another process.

Abstract: HOME TELEPHONE EXCHANGE ABSTRACT OF THE DISCLOSURE       A telephone system used in the home which provides special services such as intercom, paying, remote turn on or off of power contacts, audio monitoring, etc.  A central control is interposed between the subscriber's line and the local wiring in his home, or is connected in parallel thereto.  One or more telephone subscriber sets are plugged into the wiring as usual, contacting the tip and ring leads.  In the present invention, remote special service circuits are plugged into the telephone line, contacting the remaining two conductors, referred to below as the black B and yellow Y leads.  Each of the remote special service circuits has a specialized function, e.g., a typical circuit will have a speaker, an amplifier for driving the speaker, and a circuit for enabling the amplifier and connecting it across the black and yellow leads once an address has been received on the black and yellow leads.  Preferably, a housing containing this type of module has a socket into which a subscriber's telephone set can be plugged, and the circuit itself is connected to the local telephone line, connecting the telephone set directly or via a switch to the tip and ring leads and connecting the amplifier and enabling circuit to the black and yellow leads.  Each telephone set thus will have a local speaker associated with it.  However in a typical installation there could well be special service circuits of the latter type connected to the local telephone line without having a telephone set connected into it, or located adjacent thereto.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved method for producing a composite center electrode for a spark plug is disclosed.  The method comprises the steps of forming from a corrosion-resistant metal a cup having a closed end, walls extending upwardly from the closed end to an open end and a cavity extending concentrically therein, and then forming a composite billet having closed and filled ends by inserting into the open end of the cup a billet of a metal having a high thermal conductivity and fitting tightly within the cup walls.  The method also includes extruding the composite billet into an electrode blank having an upper headed portion and a lower portion of reduced diameter extending longitudinally therefrom.  The improvement comprises the steps wherein the positions and the relative sizes of the billet and of the cup are controlled so that the former fits tightly within the cup walls adjacent the closed cup end, but terminating short of the open cup end so that the cup walls extend thereabove at the open cup end, and the cup walls adjacent the open cup end are rolled radially inwardly to form the composite billet.  The method includes the additional improvement wherein the closed end of the composite billet is first inserted into a die having a stepped bore including an extrusion orifice of reduced diameter equal to that of a desired electrode head, and is then forced through the extrusion orifice to form an elongated composite billet.  The elongated billet is inserted into a second die having a stepped bore including an extrusion orifice of reduced diameter, wherein all except an upper headed portion is forced through the extrusion orifice to form the composite center electrode.
