Abstract: The present invention relates to a mechanism and method for rigidly mounting a handrail to the interior of an elevator cab. The mechanism includes a threaded rod having a pivoting member at one end for passing through an existing or new opening in an elevator cab wall. Upon passing through the wall, the pivoting member can rotate to provide a brace against the exterior of the elevator cab wall. A base portion having a number of grooves on its exterior surface and threads on its interior surface threads onto the rod to create a solid connection to the cab's wall. The handrail, having a base portion receiver, is then securely attached to the cab by sliding over it the sleeve and having set screw(s) inserted through the handrail's receiver at points adjacent to the corresponding grooves in the sleeve.

Abstract: A fastening member includes a bolt and a nut for attaching a compressor to a vehicle body. A non-circular relative rotation prevention portion is formed below a head portion of the bolt. A washer is non-rotatably press fitted around the relative rotation prevention portion. Before the attachment, the head portion and the washer are temporarily fixed with a space generated therebetween. An elastic body, which is attached to the compressor, is disposed between the washer and the nut. A cylindrical member is provided at an inner circumference of the elastic body. As a result, when the nut is screwed, an axial force of the nut is transmitted to the washer via the cylindrical member, and the space between the washer and the head portion is reduced, completing the attachment.

Abstract: A memory system for a computational circuit having a pipeline includes at least one functional unit and an address generator that generates a memory address. A coherent cache memory is responsive to the address generator and is addressed by the memory address. The cache memory is capable of generating a cache memory output. A non-coherent directory-less associative memory is responsive to the address generator and is addressable by the memory address. The associative memory receives input data from the cache memory. The associative memory is capable of generating an associative memory output that is delivered to the functional unit. A comparison circuit compares the associative memory output to the cache memory output and asserts a miscompare signal when the associative memory output is not equal to the cache memory output.

Abstract: A one-piece flag nut having a flag portion protruding perpendicularly to the axis of a nut portion thereof such that during installation, as the flag nut rotates, the flag portion catches on any nearby structure and acts as a wrench during the installation process. The one-piece flag nut is formed by an extrusion process, and preferably formed to have ribs provided on the flag portion thereof which provide strength to the flag nut. The outer edges of the flag portion are preferably rolled to prevent the flag portion from being hung up on the structure during the installation process, thus preventing the flag nut from being properly seated.

Abstract: An improved modular antenna pole comprised of a series of aligned cylindrical sections of progressively smaller diameters. Each of the sections includes a top and bottom transverse surface and a circular flange attached to the top and bottom transverse surfaces, respectively, to permit adjacent sections to be bolted together using conventional attachment bolts through a series of complementally spaced mating bores through the flanges. Each of the bolts is held in place by a retention clip which allows the bolts to be pre-installed. A stop tab located inside the sections prevents the bolts from rotating during tightening, and eliminates the use of a conventional jam nut. This improved design also allows the bottom flange of a higher section to rest directly on the top flange of a lower section, resulting in easier assembly and a straighter and more stable pole.

A scored line extends across the width of the arm to facilitate breaking of the arm at the scored line to shorten the arm if desired.

Abstract: A fastener especially adapted for securing a liner in a pickup truck cargo box and having a bolster at the upper ends of its walls provided with flanges at its inner edge. The fastener comprises a rotatable bolt having a head at one end and an anchor member at its other end through which the bolt threadedly extends. The anchor member may be rotated with the bolt but is of such length as to engage the lower surface of the bolster after limited rotation, thereby enabling continued rotation of the bolt to cause the liner to be clamped between the bolt head, the bolster flange, and the anchor member. The construction is such that securing of a liner in a cargo box requires no openings to be formed in the walls of the cargo box.
