Abstract: A method and apparatus is provided to produce a gold, inlaid contact surface for an electrical contact device by welding gold ribbon segments to the contact device wire base prior to the coining, trimming, slotting and various other forming operations which transform the wire base into a finished contact device. The apparatus features a sequential arrangement of gripping devices which manipulate the gold ribbon for processing as stated above, a welding apparatus for combining the gold ribbon segment with the contact wire base, a cutting device for cutting the gold ribbon and apparatus for forming the finished electrical contact device. The product features a formed contact device including a wire support member and a contact material simultaneously formed and flattened, to provide a minimum amount of inlaid or coined gold for effecting desirable contact characteristics.

Abstract: A wire pulling apparatus for use in pulling multi-cable wire through a conduit by means of a mechanical or manual pulling force. The conduit is provided at its entrance opening with a bushing including a matrix of grating elements to conform the wire cables to a predetermined pattern. A first reference for the pattern is established by encasing the wire cables at their leading ends in a basket-like device to which is attached a pulling cable leading through the conduit to the pulling element of the apparatus. The grating elements are rotatably inserted through radial holes provided in the bushing and are held in place by bending or threadably attaching nuts at the periphery of the bushing. Generally vertically oriented grating elements define notches for holding generally horizontally oriented grating elements. Furthermore, the bushing is provided with a smooth lip for preventing destructive contact with the wire cables.

Abstract: An orthodontic appliance with metallic reinforcing members in the form of wires embedded in a plastic base. The metallic reinforcing members include ligatable projections as part of the ligature system for the appliance.

Abstract: Dental appliances such as orthodontic apparatus in the form of a coated metal having characteristics including aesthetic appearance highlighted by tooth coloring, resistance to abrasion, low friction, weldability, stability at high temperatures and attachability to dental adhesives. A base metallic material is covered by a coating including a para-oxybenzoyl homopolyester and polytetrafluoroethylene and a pigment for providing the tooth coloring.

Abstract: An athletic shoe assembly for convenient removal and replacement of a spike therefor. The assembly includes an inner plate between the inner and outer soles of the shoe or between the inner sole and the heel of a shoe. Attached to the inner plate is a spike receiving member defining opposed slits in the sides thereof, into which protrudes opposed retaining springs anchored within the outer sole or heel of an athletic shoe. The spike assembly includes an outer plate, a spike member defining opposed removal channels and sealing means for preventing the clogging of the spike removal channels during use. A spike removal tool is also provided for disengaging the spike member after it has been used by insertion to the spike receiving member.

Abstract: An athletic shoe, with attached spike plates, depending from each of which are a plurality of spikes. Each spike plate defines a central opening through which is mounted a cleaning member mounted by a spring or another form of resilient member. The athletic shoe portion beneath each spike plate is recessed for mounting of the resilient member and for enabling the cleaning member to be pressed therein without exposure outside of the athletic shoe to a point below the spike plate.

Abstract: A fluid flow regulator is inexpensively constructed in a unitary system with a rigid and transparent drip chamber overlying a rigid float chamber. The purpose of the regulator is to control the dispensing of physiological fluids or the like to be infused into the circulatory system of a patient. The unitary structure is essentially cylindrical in shape divided by a median wall into a top cylindrical portion functioning as a drip chamber and a bottom cylindrical portion functioning as a float chamber. The two chambers are connected by a pressure equalizing air tube and neither chamber is vented to the outside atmosphere. Such pressure equalization makes the system self-compensating for the purpose of maintaining a constant head for the fluid between the drip chamber and the float chamber.

Abstract: An adhesive system is described as including an adhesive having dispersed metal particles whose function it is to emit heat for the purposes of breaking the bond formed by the adhesive when such action is desired. Specifically, metal particles are embedded within a suitable adhesive material which loses strength at a predetermined, relatively low temperature. When it is desired to break the bond formed by the adhesive, the metal-filled adhesive is placed in a rapidly varying magnetic or electromagnetic field so that the metallic inclusions transfer heat to the adhesive material, thereby raising it to a level which will break the bond formed thereby.

Abstract: A liquid administration apparatus includes a closed fluid system enabled by a double bore metering tube which leads from an intermediate sump fed by a supply container to a flow controlling float chamber. The supply container can either be of the flexible bag type or the bottle type, both commonly used for infusing physiological fluids into the circulatory system of a patient. The float chamber is movably mounted on a flow indicating scale to set calibrated rates of flow. The sump is divided into a reservoir portion and an over-flow portion by a dam and an air inlet tube projects above the dam. A liquid inlet means leads from the reservoir portion through a metering tube to the float chamber. The float chamber includes a float which is buoyed by liquid entering the float chamber and centered by splines projecting inwardly of the float chamber. The float in the float chamber functions as a valve to selectively open and close a port leading to the infusion needle of the apparatus.
