摘要： An adjustable load tear bar mechanism for a friction feed platen (15) that comprises a tear bar assembly (31) and spring loading mechanisms (33) is disclosed. The tear bar assembly (31) comprises a tear bar (51) mounted between a pair of side arms (41, 43) located on opposite ends of the platen (15). The tear bar (51) is an inverted, generally U-shaped channel. Positioned in the channel is a roller shaft (45) on which a plurality of friction feed rollers (47) are mounted. The downstream ends of the side arms (which overlie the platen) are pivotally attached to walls (11, 13) of the printer chassis. The tear bar (51) and roller shaft (45) extend between the upstream ends of the side arms (41, 43). Mounted on the roller shaft (45) so as to be rotatable therewith are arm hooks (53, 55). One of the arm hooks is part of a detent mechanism that includes teeth (125) that co-act with a spring (59) and plunger (57) housed in one of the side arms (43). The position of the teeth (125) and, thus, the rotational position of the roller shaft (45) is controlled by a detent lever (121). The arm hooks (53, 55) are attached by the spring loading mechanisms (33) to the printer chassis. More specifically, the hook arms are attached by hooks (165) to springs (163) mounted in housings (161) connected to the printer chassis upstream of the tear bar (51). The position of the arm hooks (53, 55), which control the pressure applied by the tear bar (51) and friction rollers (47) to the platen (15), is controlled by the latched position of the detent mechanism.

摘要： An apparatus is provided for the automatic assembly of nuclear fuel rod bundles in a predetermined coordinate array. Each fuel rod is identified during its travel and positioned according to an identifying code carried on its lower end plug which designates the fuel enrichment and additive level of the rod.

摘要： A portable spa in which a confining outer wall rests on the ground or other flat surface. A water impervious liner is suspended from the top of the wall and forms a barrier for holding water. The liner is formed with a double-wall construction with an inner sheet attached around the margins to the outer sheet to form a confined space. A pump for recirculating water through the pool has its outlet connected through a conduit to the confined space so that water is forced into the confined space under pressure. A portion of the inner sheet is shaped to form a raised seat on the bottom of the pool when inflated, while another portion of the inner sheet extends above the seat to form a back rest when inflated. The pump directs water through a series of jets through the sides of the pool to provide a massaging action.
