    摘要: A drill bit having a central shank having an "S" shaped cutter integrally formed on or detachably secured to the shank. A collar is detachably secured to the shank above the cutter and is keyed to the cutter to prevent rotation of the collar. A generally flat secondary cutter is secured to the collar and has a plurality of depending cutter elements on the peripheral edge thereof as well as a plurality of radially extending chisel cutters depending therefrom.

    摘要: A lightweight permanent concrete footing form section includes a base sheet that is horizontal with substantially planar upper and lower surfaces. Side walls integral with the base append upward from the base in a generally vertical and planar direction. Ducts are attached to the side walls for carrying water away from the concrete footing after the concrete has been poured and set. Sections may be interconnected and dimensioned according to plans.

    摘要: Low voltage electric switchgear equipment includes a central processor unit electrically interconnected with electronic main and branch circuit interrupters within the same enclosure and used within a multi-phase power distribution circuit. A terminal connector block is connected by cable with each of the electronic trip units within the branch circuit interrupters to provide communications between the branch circuit interrupters and the main circuit interrupter for continuously updating the status of the branch circuit interrupters and their associated electrical equipment. Strain relief is provided to the cable connecting between the terminal connector block and the branch circuit interrupter to prevent damage to the electrical components within the electronic trip unit that are internally connected with the cable.

    摘要: A chain link fence system has end, corner, or gate posts, each comprising a tubular metal post with a series of spaced, vertically-aligned openings along at least one side thereof. A supporting cross bar extends from one post to another and has a horizontally-positioned, apertured tonguemember at each end positioned in the top side opening of the post with the apertures oriented vertically. The end links of a chain link fence are positioned in the vertically aligned openings and a retaining rod inserted downwardly through the aperture in the tongue member and through the end links of chain link fence to secure the cross bar and the chain link fence wire to the post. A cap member covers the top of the post. The chain link fence is preferably secured to intermediate line posts by a novel retaining wire tie of a heavy bendable wire having the initial shape of a shepherd's crook and self closing at the crook end when properly installed. An alternate embodiment has a plurality of retainer members which fit in and are retained by the openings in each post and have openings which receive a retaining rod to secure the ends of a chain link fence thereon.

    摘要: Disclosed herein is a lock suitable for use with sliding type windows which are constrained to ride within trackways. The apparatus comprises a pair of links pivotally connected having tab portions to provide for manipulation of these two links relative to each other and a biasing apparatus which tends to retard the two links from assuming a position in which one link would substantially totally overlie the other link. Further, downwardly extending tabs provide the nesting area for opposed extremities of the biasing spring which is wrapped in a preferred embodiment around the pivoting juncture of the two links and these tabs ride in the trackway or channel of the sliding windows and provide a resistive reaction to unauthorized opening of the window to such an extent that the window can not be opened in the conventional manner.

    摘要: A compact circuit breaker containing an electronic trip unit employs an actuator-accessory unit to articulate the circuit breaker operating mechanism and separate the circuit breaker contacts to interrupt current within a protected circuit. A tolerance compensating spring is attached to the actuator-accessory unit trip armature to precisely set the separation gap between the tip of the armature and the actuator-accessory trip actuator arm.
