Abstract: An electrical receptacle assembly for attachment to a luminaire housing comprises a housing defining a plurality of contact seating channels extending therethrough along axes parallel to a contact member insertion axis, electrical contact members being seated in the housing channels individually along the axes parallel to the contact member insertion axis. A clamp member is joined to the housing by a threaded fastener. The housing defines an anti-rotation member resident in the clamp member which prevents the clamp member from rotational movement relative to the housing upon tightening the threaded fastener.

Abstract: A cable connector clamp for an insulated electrical cable is preferably integrally moulded from a resilient plastic material. It has a cylindrical housing defining a passage for the cable, and a slot to permit its insertion into a knock out or opening of an enclosure wall. Within the housing, there is a clamping element extending across the passage and resiliently deflectable, to permit insertion of a cable. The clamping element includes a clamping lip that is resiliently pressed against the cable to prevent its withdrawal from the connective clamp. To assist in clamping the cable, one or both of a clamping lip of reduced thickness at the free end of the clamping element, and additional projections on the inner wall of the housing are provided. The additional projections have abutment faces, perpendicular to the axis of the housing and facing the second end of it.

Abstract: A buried service splice enclosure for sealing a splice of telecommunication cables comprises a closure defining an interior space for accommodating the cable splice and defining an opening for receipt of the splice therethrough. A closure seal sealably closes the closure opening and has apertures for receipt therethrough of the cables. Means are provided for sealing the closure seal to the closure and for sealing the cables to the closure seal at the apertures. An inlet fitting, such as a check valve, communicates with the closure interior space and is adapted to receive and pass an encapsulant under pressure into the interior space. An outlet fitting, such as a pressure relief valve, also communicates with the interior space, the pressure relief valve adapted to pass the encapsulant therethrough when the encapsulant is exposed to a predetermined pressure in the closure interior space.

Abstract: A filtering apparatus for use generally in filtering the fluid of an aquarium. It consists of a clear housing that is submerged within the tank with this housing having both intake and discharge openings therein for the passage of fluid therethrough. This housing is further configured with a series of channels formed therein for directing the flow of fluid within the housing to the filter. A removable filter is mounted within the housing and is coupled to the discharge opening which, in turn, is coupled to a pump. The housing is openable so that access to the filter is provided when the filter needs to be replaced. Also, adjacent each intake opening is a flap to permit only one-way flow across the intake openings and into the housing.

Abstract: A shield that is normally positioned or wrapped around a boiler tube when such tube is exposed to extreme operating conditions. This shield consists of an elongated strip of thin material that is formed as a helix. This strip also incorporates a means for spacing this strip from the tube so as to create a gap between the tube and the shield. Generally the shield is secured to the tube by spot or button welding only the longitudinal end regions of the strip to the tube. By thus wrapping and securing one or more such shields to the tube, the tube is protected while still permitting both it and the shield(s) to expand and contract as needed.

Abstract: A flexible, pressurized insert for insertion within the hot (evaporator) side of an inclined heat pipe that forms a part of a heat pipe heat exchanger. This insert is employed in order to prevent such heat pipe from rupturing in the event the working fluid contained therein freezes. This insert is constructed of a thin-walled flexible material that is capable of being deformed (i.e. compressed) thereby absorbing the expansion pressures exerted by the working fluid should the working fluid freeze or be exposed to freezing temperatures. By such absorption, the outer heat pipe itself will not be over-pressurized which might otherwise lead to its rupture. Upon the thawing of the working fluid, the pressurized insert (which is at a pressure greater than that of the working fluid in its non-frozen state) will once again regain its shape.

Abstract: A cooling system for passively cooling an enclosure incorporating at least one inclined heat pipe having an evaporator side extending within the enclosure and a condenser side extending outside the enclosure in contact with the ambient environment. A thermal storage device within the enclosure is configured having a first portion extending adjacent the evaporator side of the heat pipe and a second portion extending within, and generally concentric with, the evaporator side of the heat pipe. A solid-to-liquid phase change material is sealed within this thermal storage device such that this material changes to a liquid upon the absorption of heat. To further enhance the transfer of heat from within the enclosure to outside the enclosure, a series of fins can be added to the first portion of the thermal storage device as well as to the condenser side of the heat pipe.

Abstract: A method for making an electrical connector comprises the steps of configuring a housing and contact members such that the contact members may assume positions in the housing which are variable for each contact member and of assembling the contact members in the housing such that they assume positions therein giving rise to contact member coplanarity. An electrical connector so made comprises a housing defining contact member receiving channels and contact members resident in the channels, the contact members defining contact portions and contact member retaining means, the housing being configured to permit variable positioning of said contact member retaining means therein, whereby contact member contact portions may be coplanarly positioned irrespective of warp present in the housing.

Abstract: A shielded electrical connector provides continuous ground shielding about the connector. The connector includes a plurality of electrical contacts having contact tails. An insulative body insertably supports the contacts. A conductive housing having an open end is positioned over the insulative body, the contact tails extend outwardly of the conductive housing. An end shield is positioned adjacent the open end of the conductive housing. The end shield surrounds the contact tails providing shielding therebetween and is in interlocking engagement with the conductive housing thereby establishing electrical ground path continuity between the conductive housing and the end shield.

Abstract: An electrical connector provides for the termination of discrete insulated conductors of a multi-conductor cable. The connector includes an insulative connector housing supporting plural electrical contacts having insulation displacing contact portions. A conductor holding block is movably supported by the housing with respect to the insulation displacing contact portions. The conductor holding block includes contact slots for receipt of the insulation displacing contact portions. The conductor holding block further includes passages in communication with the contact slots for receipt of the conductors. Deflectable fingers extend into the passages to provide for support of the conductors and for the accurate alignment of the conductors over the insulation displacing contact portions upon movement of the conductor holding block with respect to the electrical housing.

Abstract: A twist-on electrical connector connects plural insulated electrical conductors. The connector may be manually twisted onto the conductors by an installer. The connector includes an outer insulative shell and an expandable spring held within the shell. The shell includes a pair of generally diametrically opposed wings which may be gripped by the installer to facilitate twisting of the connector onto the wires. The wings conform to the fingers of the installer to permit the easy gripping and twisting of the connector onto the conductors.

A flame sensor is provided for detecting and a sensing the existence of pilot flame and for controlling the gas flow to the burners accordingly.

Abstract: A twist-on electrical connector connects plural conductors, preferably stripped ends of insulated conductors. The connector includes an outer insulative shell having a cavity open at one end. The cavity supports an expandable generally conical spring which accommodates the conductors. The shell includes plural ribs extending into the cavity for engagement with the spring upon radial expansion thereof. The ribs have tapered extents so that the ribs deform in both the radial and transverse direction upon expansion of the spring to control the rate of spring expansion.

Abstract: A wiring patch panel cabinet accommodates plural termination devices. A cabinet support structure includes spaced apart top and bottom walls and opposed sidewalls. The cabinet support structure secures a plurality of individual patch panels. Each patch panel accommodates termination devices of a given type. The termination devices of one patch panel may be different from the termination devices of another patch panel supported by the cabinet structure. The patch panels are supported by the cabinet in side-by-side vertical orientation to facilitate removal and repair of an individual patch panel without disturbing adjacent patch panels.

Abstract: A timing chain adjusting device that is inserted upon the crankshaft of a partially disassembled engine. The timing chain adjusting device is rotated (along with the crank shaft) to align the crank shaft in the top dead center position. Subsequently, the cam shaft is likewise rotated to be in alignment with the crank shaft and the timing chain adjusting device is installed to insure that the crank shaft gear and the cam shaft gear were properly positioned with respect to each other before the timing chain was installed.

Abstract: A method and apparatus for venting the seal air pressure within an isolated system so as to obtain a relatively small, in the range of 4 to 8 inches water gauge more or less, pressure differential across the isolation dampers. This small pressure differential is desired so as to reduce the load against which the dampers must operate thereby permitting a more economical design of such dampers.

Abstract: An animal feeding or injecting device for orally supplying liquids, slurries, gels, and some solids to an animal. This device consists of a tubular container having a tapered end region and an opposite open end through which a plunger passes. A stop or collar is slidable along the outside of the tubular container which not only restricts the distance the plunger can be inserted within the tubular container, but also prevents the tubular container from being inserted too far within the animal's mouth. A connector is secured to both the stop and the plunger so as to prevent the plunger from being inserted too far within the tubular container.

Abstract: A vehicle locating and alarm system that enables the user to remotely access the vehicle and, if need be, activate an alarm system therein. This system also automatically calls one or more pre-programmed telephone numbers upon the occurrence of certain events, such as a collision or other emergency. Upon remotely accessing the vehicle by telephone or computer, the user is, upon entering a valid Personal Identification Number ("PIN"), supplied with the vehicle's location, speed and a command option menu for alarm and deterrent device control.

Abstract: An apparatus for removing machine lines from the gasket groove in the flanges of a header box has a support plate mounted for linear movement on rails connected to the header box. The support carries a tool driver which can be pivoted below the support to bring a grinding or polishing tool, rotated by the tool driver, into and out of the groove for grinding and polishing away the machine lines in the groove as the support slides along the rail. This grinds and polishes the grooves while avoiding a wavy effect which was a disadvantage of using a hand-held grinder for the same purpose.

Abstract: A method of wet flue gas desulfurization of combustion gases that incorporates both calcium scrubbing with forced oxidation and ammonia scrubbing of the gas in a scrubber tower. The end product or result from such a process is gypsum and ammonia sulfate which may be used in agriculture.
