As disclosed, the electrical connector includes an elongated insulator block carrying contacts in the form of pins, an end of each of which is received in a printed circuit board aperture to be soldered to the printed circuit board. The elongated insulator block further includes a series of holes, each intermediate an adjacent pair of contacts of the connector, precisely located relative to the contact locations, to facilitate positioning the connector for insertion of the pins into a printed circuit board. The insulator block is notched adjacent each of the holes to facilitate breaking the connector to a desired length, and hence containing a desired number of contacts. The insulator block further has generally semi-cylindrical indentations at each of its ends.

Abstract: A pivot fastener construction useful in coupling two parts. The pivot fastener prevents unwanted separation of the parts coupled while permitting the parts to rotate relative to each other. The blind pivot fastener has bushing members which can be secured in fixed relationship to the parts coupled by threading, press fitting, expansion fitting or the like. The advantages of the construction may be utilized in both assembled and unassembled pivot fasteners. By changing specific aspects of the design, such as assembled/unassembled, means of securing the bushing members, use of a separate bearing post member, etc. the specific construction may be altered in response to specific application needs.

Abstract: Improvements in plastic coated, steel core reinforced manhole steps; particular improvements in the drive-in or hammer-in ends of a U-configuration manhole step construction, which improvements involve providing resilient, barb-like retainer elements in the drive-in ends yet relieving such in particular patterns so as to enable debris and water in the formed holes in the manhole to escape in order to protect the concrete against conveyed impact pressures and further enable more effective sealing and engagement of the manhole step ends with the manhole wall orifices; particular improvements in drive or hammer-in manhole steps of the plastic coated, steel core reinforced type wherein the drive-in ends of the manhole steps are so relieved in the end portions thereof as to obviate and prevent any sealing of the recesses or holes in the manhole proper; improvements in wedge tooth or barb configuration to achieve maximum pullout resistance while retaining pressure and material relief features.

Each leg member is formed by two wall elements molded together in a V-shaped configuration wth the outer end portion laterally spaced apart from the adjoining leg member a distance sufficient to embracingly receive the pair of leg members of the identical fastening device. When the identical fastening devices are brought together in a nesting relationship, they are locked together by virtue of the interlocking cooperating relationship of a plurality of tooth formations formed on one of the two V-shaped wall elements of each leg member.

Abstract: A one-piece plastic wing-nut fastener is constructed to push onto a threaded stud and be held in threaded engagement therewith through the use of a pair of opposing arcuate thin wall sections which are formed with internal threads and which flex radially outward whenever the fastener is pushed onto a threaded stud to provide a ratcheting action therebetween. The thin wall sections are supported on a base member by a U-shaped support having a head section and a pair of leg portions. The pair of leg portions are integrally formed with the base portion and extend between the base portion and head portion in a parallel relationship with the thin wall sections. The pair of thin wall sections are integrally formed between the base and the head portion with its axis in alignment with an enlarged aperture in the base portion and an enlarged central opening in the head portion.

Abstract: A modular window assembly includes a glass panel with a peripheral molded PVC frame having an undersurface engageable with a pinchweld flange defining a window opening in a vehicle. A plurality of cylindrical, finned PVC studs are integrally molded to the PVC frame undersurface and are alignable with slots through the pinchweld. A central passage extends axially through each stud, most of the way, but not all the way therethrough. The diameter of each stud is slightly larger than each pinchweld slot. A pin in each central passage, when pushed, stretches the studs, decreases their diameter so that they pass through the pinchweld slots. Releasing the pins lets the studs resiliently return to their original shape to retain the window assembly to the vehicle.

The push button is provided with an opening for each resilient finger, which opening extends from outside the button towards the locality of the end face of the resilient finger and is of a dimension to eclipse, or cover the cross-section of the resilient finger when projected onto the plane of the opening.

Abstract: A closure is provided for sealing and repairing a puncture of a tire. The closure is a resilient plug of a rubber-like material stiffer and more durable than prior closures having a generally cylindrical shank portion and an adjoining circular head portion. The periphery of the shank portion has a labyrinth of closely spaced sealing rings and grooves therebetween. When the shank portion is forcibly engaged with a puncture, the sealing rings individually radially compress and locally conform to the size and shape of the puncture thereby providing multiple sealing members with the puncture. Additional sealing is provided by an auxiliary sealing ring on the head portion of the closure which is adhesively bonded to the inner surface of the tire, adjacent to the puncture. Tool attaching means are provided on the closure for forcibly engaging the closure with the puncture.

Abstract: A multi-part fastener assembly for attachment of a carpet-like member to a support. The fastener is designed to minimize snagging and/or scraping-type of engagement with objects that come in contact therewith. The exposed fastener part is an annular member which has a radiussed outer edge from which a plurality of rigid projections extend. The projections are designed to be able to penetrate the carpet-like member and a radially extending flange of another fastener part and be folded to fixedly position the fastener relative to the carpet-like member. The radially extending flange has areas of reduced thickness to ease the projections therethrough and is deflected to create an annular mounding of the carpet-like member around the annular member to cooperate therewith in increasing the resistance of the fastener to snagging type of engagement.
