Abstract: A cup for use in medical electrode structures comprises a one-piece body of plastic having a cup shape and thus having a base and a rim. The rim is rounded for comfortable skin contact and has integrally formed barbs projecting inwardly and downwardly toward the center of the cup. The barbs permit a prefilled electrolyte sponge to be dropped into the cup without appreciable resistance from the barbs, but resist any tendency for the prefilled sponge to separate from the cup. Accordingly the cup supports the prefilled electrolyte sponge for contact to the skin of a patient but resists any tendency of the sponge to escape the cup by clinging to the patient's skin.

Abstract: An electrical socket and associated circuitry is provided wherein current can flow to the socket only when a load device is in the socket and a normally open, momentary "make" switch is closed. The circuitry includes a relay for actuating a switch in parallel with the momentary make switch, which relay is energized upon closure of the momentary make switch and remains energized so that current will continue to flow to the socket until a normally closed, momentary "break" switch is opened. Current cannot flow through the socket with the load device removed even if one should touch the socket except in the unlikely event the make switch is closed.Several embodiments are disclosed wherein no current can flow through the socket unless at least three socket parts are engaged. In one form of socket, the socket base contact is divided into two parts, both of which must be engaged in order for the relay to remain energized.

Abstract: An industrial screen of the type having generally parallel wires looped about transverse support rods has chromium plated to at least the surfaces of the wire elements which contact one another in use. In the preferred embodiment hard chrome plating of entire wire elements is utilized.

Abstract: Lead wires from the field coils of a two-coil, two-pole stator for a motor of the universal type are wound about posts projecting outwardly from a wire retainer mounted to the stator by means of cannulas encircling said posts and having hook portions for engaging the coil lead wires. Lead support means support leads emanating from already wound field coils at positions adjacent said posts, there being four posts and four cannulas, each telescopically encircling one of said posts. Drive means simultaneously rotate all four cannulas in directions appropriate to cause the hook portions thereon to engage the four leads emanating from the two coils and continued rotation of the cannulas causes the hook portions thereon to wind the lead wires about the posts as the lead support means permits the lead wires to be drawn therethrough while maintaining the lead wires under tension as they are wound about the posts.

Abstract: An electrically energized aluminum melting furnace comprises a vessel for supporting molten aluminum and a roof and upper wall structure cooperating with side walls of the vessel to define a heating chamber above the molten aluminum. A plurality of unshielded resistance heating elements are supported by the roof and upper wall structure above the molten aluminum. The molten aluminum has access through a submerged opening to a charging well to which unmelted aluminum is periodically charged without danger that molten aluminum will splash upon the heating elements. Heat conducted from the heating chamber through the body of molten aluminum residing in the vessel is utilized to melt in the charging well the aluminum charged thereto. The melted aluminum in the charging well is permitted to flow through the heating chamber and through a submerged opening to a hot metal well from which hot metal may be withdrawn by any of numerous techniques.

Abstract: There is disclosed a cup-like container closure of resilient and flexible thermoplastic material having a removable tear strip defined by an annular groove on the inner surface of the closure skirt. The tear strip includes a gripping portion adjacent opposite ends of the strip which are separated by a narrow gap. The closure skirt is substantially cylindrical and free from outwardly depending portions. Contents of the container are effectively sealed therein by tight interengagement of cooperating surfaces of the container and the closure. The closure is re-usable for closing the container after removal of the tear strip.

Abstract: An electrode for sensing signals such as electrocardiograph signals used with an electrolyte is formed from an electrically conductive but galvanicallly inactive material having a galvanically active conductive material at the electrolyte interface. Examples are described including a body formed from a plastic or other non-conductive binder rendered conductive by inclusion of finely divided conductive carbon and having one or more metal particles anchored to the surface of the body which contacts the electrolyte.

Abstract: Automatic machinery for performing multiple operations on different parts of workpieces includes an incrementally rotating, workpiece supporting turret provided with three workpiece supports. Upon rotating of the turret, a workpiece loaded on a support located at a first position is indexed about the axis of the turret to a second position at which a first operation is performed thereon, then to a third, idle position. Continued rotation of the turret results in an index of the workpiece to the first position, then again to the second position at which a second operation is performed thereon. After the next index to the third position, the workpiece is unloaded from the support. As the turret is indexed, the workpiece is rotated relative to the turret whereupon the workpiece is oriented differently each time it reaches the second position causing the operations to take place on different parts of the workpiece.

Abstract: A machine for winding wire coils on an armature core and connecting the coils to commutator tangs including a pair of fliers and an armature rotating mechanism particularly controlled to completely loop the coil lead wires about suitable commutator tangs circumferentially offset from the sides of wound coils and to completely wrap the wires around the armature shaft.

Abstract: A socket base contact is self-biased to a position remote from its terminal and an insulating plate is driven by a spring between the contact and the terminal when a load device is removed from the socket. When a load device is inserted into the socket, the insulating plate may be manually moved to permit engagement between the base contact and its terminal. The force exerted against the base contact by a load device in the socket is sufficient to prevent the insulating plate from being driven between the base contact and its terminal.

Abstract: A lubricated joint assembly comprises joint means received in a boot having cuffs which allow coupling members to connect between the joint means and external mechanisms. The boot cooperates with the coupling members to fully enclose the joint means. The boot is pressurized with a lubricant charged thereto whereby the boot is expanded and compresses the lubricant therein. In the preferred embodiments, the lubricant is charged to the boot in a fashion which displaces all air from the boot, thus preventing oxidation of the lubricant. Further, in the present invention, the external shape of the expanded boot is controlled by controlling the shape of the boot before pressurization thereof and by also controlling the wall thickness of the boot in selected areas thereof.
