The kit, for one or two receptacles mounted within the pre-set, includes an adjusting ring, a pair of access hatches, and a pair of receptacle plates.

Abstract: In the manufacture of electrical spring contacts each having a gold-plated contact element welded thereto, a method of providing such a contact element by welding a gold-plated surface strip to a body strip with a pair of welding electrodes in the form of rollers located between the punch and die pad bolsters of a progressive die to effect one or more welds between the strips during the interval the punch pad bolster is in its return stroke mode whereby the subsequent punching out of the finished contacts can be done without disturbing the welds and each such welded part of the surface strip constitutes the gold-plated contact element.

Abstract: Poke-thru has floor fitting serviced by a thru floor unit in a bore in the floor and carries power and/or communications conductors. The thru floor unit comprises a pair of mounting screws which extend down through the floor fitting base with the heads engaging the base. The mounting screws carry a flexible finger type retaining clip to grip the side of the bore. Above the retaining clip, on the mounting screws, are top separator means which maintain the clip and base a fixed distance apart. Intumescent material and a top spacer are loosely disposed in the space between the clip and the base. Below the retaining clip, on the mounting screws, is a bottom spacer. Below the bottom spacer are top and bottom retainers held a fixed distance apart by separator means. Intumescent material is loosely disposed in the space between the top and bottom retainers. The bottom retainer has nuts in which the screws are threaded.

Abstract: Corrugated carton is moved between sprayers which apply water to the score lines of each major end flap and on opposite sides of the score bar about 1" up on the flap and 1" down on the panel. The major flaps are then bent into closed position and while bent, heat is applied to raise the temperature of the wet areas until the same are dry. Then, the bending means and heat are removed. Each end flap assumes a substantially closed position.

The desk is useful in support of the activities of traveling business persons such as sales, engineering, and management personnel over and above such desk now known in the trade. The desk having structure to hold important items required by traveling business persons in easily accessible compartments and in a manner such that the items cannot fall out or migrate between compartments when the desk is being carried or shipped. The desk having a two-section cover, the sections being respectively arranged to be pivoted upward to provide access to the whole of the interior or to a part of the interior.

Abstract: Box has a hollow main housing and means which separates the housing into two power sections and an electrically isolated communication section between the power sections. Each power section has a receptacle. An opening above the communication section provides access to the communication section and to the receptacle plug-in heads. The housing mounts wire connectors for each power section for receiving the head of a cable set. A passageway under the communication section allows power conductors to connect the receptables in the power sections.

Abstract: A junction box having an access unit adapting the box for use in floors having carpet or tile as floor covering whose construction contemplates an adjusting ring having a flange which function both as a trim for carpet or tile on the cover and as trim for carpet or tile on the floor.

Abstract: A control device in an anesthetic administering system which senses the dangerous condition of nitrous oxide flowing to the patient's breathing mask in the absence of oxygen flow to the mask and provides a warning signal so the condition is known and, thus, is correctable.

Abstract: Fitting comprises an attaching ring secured to a pair of adjacent underfloor ducts and spanning the pre-punched access holes in the ducts, the attaching ring retains adjusting screws which in turn support an adjustable carpet plate which carries power/telephone outlets.

Abstract: A device used in overhead power distribution systems to serve solely as a cable coupler, i.e. join or splice a pair of flexible connecting cables having a plug-in connector at opposite ends or alternatively slightly modified so to serve as a wiring adaptor, i.e. to be secured to a unit to be energized and provide the power either from a single flexible cable or from a pair of flexible cables which are spliced together. A typical example of a unit to be energized is an overhead lighting fixture or a service pole.

Abstract: A ribbon dater which has, improved structure: (a) to quickly reverse the direction of movement of the ribbon so that the same can be re-run thru the printer; (b) to quickly reverse the direction of movement of the ribbon and at the same time provide for a different half of the ribbon to effect the printing; (c) to initiate the printing operation; and (d) to increase printing efficiency but that the type, the ribbon and the part to be printed are all held fixed and printing effected by a movable striker.

Abstract: The mobile has twelve elongated members positioned with respect to one another to create the appearance of a hexahedron. At each of the eight corners is a flexible joint means joining three rods together and permitting the rods to pivot relative to one another (but maintaining their attachment) so that exterior forces such as air currents or mechanical thrusts cause the mobile to move in an undulating fashion and thereby create changing hexahedron shapes or patterns. The mobile is suspended from a ceiling or from an arm on a stand. Suspension is attained by a pair of threads which are respectively attached to an opposite pair of top members.

Abstract: Service poles having improved structures, namely: extruded aluminum frame with special slots to removably retain covers and to mount receptacle retainers; pole hanger adapted for use with various sizes of poles and also adaptable to secure pole to a ceiling panel T-bar suspension system or alternatively to a floor supported suspension rod; base adapting pole for use on tile or carpet; ceiling tile trim plate adaptable for use with various sizes of poles and for use regardless of the point where the pole passes thru the ceiling panel; retainers for supporting single and duplex receptacles.

Abstract: For use in connection with the adjusting spindle of a vehicle wheel brake of the kind wherein the adjusting spindle is accessible through at least one slot formed in the wheel hub, a tool adapted to be temporarily secured to the wheel hub and in such condition maintain the adjusting lever and star wheel out of engagement whereby both hands of the mechanic are free for turning the wheel and for adjusting the star wheel.

Abstract: Vent window and rear-view mirror are integrated to provide a composite, unitary structure which achieves important advantages not available with conventional separate windows and mirrors.

Abstract: The box has a base for mounting on a surface and a cover secured to the base by screws. A pair of tabs are disposed close to the base end of the cover and each tab captivates a screw. Assembly of cover to base is simplified because the cover can be held in one hand while a screw driver in the other hand turns the screws. Inventory is reduced because a single length of screw is employed irrespective of box depth.

Abstract: Measuring apparatus has a pair of cavities which are put into a charge position to respectively receive precise quantities of resin and hardener from supply sources. The quantities are then transferred to a discharge position wherein the resin and hardener are pushed out of the respective cavities to feed a mixer. The additional material entering the mixer causes the same to eject mixed resin and hardener equal to the unmixed resin and hardener received.
