Abstract: A connector is provided that can be coupled with a low inserting force and that will not terminate coupling operation while it is in an incomplete coupling state. The connector comprises a pair of housings coupled to each other, a pivotal piece pivotally provide on one of the two housings, a spring interposed between one housing and the pivotal piece, and a latch means for locking the two housings that are coupled to each other. When the two housings are coupled, and after the two housings reach a predetermined intermediate coupling state, the pivotal piece is pivoted by the spring, thereby completing coupling of the two housings.

In addition, terminal portions are formed as box-shaped terminals to obtain a reliable and stable engagement with a CRT anode electrode.

Abstract: A lighting fixture for use in hazardous locations and adverse environments, includes a mounting plate and a first ballast housing. A second non-interchangeable ballast housing may be alternately employed by use of an adapter ring removably securable intermediate the mounting plate and the second ballast housing. The adapter ring comprises a top portion specially adapted to engage the mounting plate, with first fastening means associated therewith, and a bottom portion specially adapted to engage the second ballast housing, with second fastening means being associated therewith. The adapter ring allows the replacement of the first ballast housing with the second, wherein the first and second ballast housings are not identical and are produced by different manufacturers. The adaptor ring effectively seals the interfaces with the mounting plate and second ballast housing, thereby maintaining the integrity of the lighting fixture for its intended purpose.

Abstract: A connector body member has conductor receiving sections for receiving a plurality of conductive end portions of a member to be connected, such as a flat cable, a jumper, or a printed circuit board. A plurality of contacts are so mounted as to project into the conductor receiving sections in order to contact the conductive end portions of the member to be connected. A cover member for holding the contact between the conductive end portions of the member to be connected and the contacts is formed to be pivotal with respect to the connector body member. Each conductor receiving section has an opening. The cover member pivots to cover the openings of the conductor receiving sections. The cover member is also locked into the connector body member by sliding along the connector body member while covering the openings.

Abstract: An electrical connector (30) having crosstalk reduction between selected pairs of electrical contacts comprises a printed circuit board (36, 36') having a pair of circuit elements (40, 42) therein connected through welding pads to selected contacts (6, 3) the connector. The signal paths of such selected contacts are severed and then are re-routed by means of the pattern of circuit elements in the printed circuit board, each circuit element balancing the mutual inductance in such re-routed signal paths for enhanced crosstalk reduction.

Abstract: Information of the type, number, burying depth and direction of a pipe or other objects buried in the ground is identified on the ground surface. There is provided a buried marker comprising an identifying plate having indicia thereon and an interconnect band for interconnecting the identifying plate to the object buried in the ground. The position where the pipe or other object is buried is thus easily identified.

Abstract: A traceable transmission conduit assembly includes an optically transmissive jacket over a transmission conduit. The conduit, which may be an optical fiber, includes a light transmissive and translucent jacket thereover. Light is injected into the jacket at one location therealong. The light is emitted along the length of the jacket so that the jacket illuminates. One conduit bundled among a group of similar conduits may be traced by so illuminating the jacket of the one conduit.

Abstract: Apparatus for suspending and connecting a pair of tubular members, particularly a pair of radiant heater tubes, wherein each tubular member has an expanded end and a straight end so that successive tubular members are connected by slip joints. The suspending and connecting apparatus of the preferred embodiment includes a pair of brackets fixedly secured to the body of one tubular member generally adjacent to the straight end thereof, and a pair of semi-circular clamping members forming a ring about the adjoining tubular member and engaging the expanded end thereof. Holes formed in the clamping members and brackets are alignable so that a pair of screws may be inserted therein to operatively engage a pair of nuts retained by the brackets. The brackets include holes for attachment to conventional suspension systems, so that one bracket for each tubular member may be employed to suspend the assembly from a ceiling or other overhead support structure.
