Abstract: A scrubber head has a handle with connections for parallel hoses to an adaptor which is interposed between a shower supply line and a shower head. A first valve in the scrubber head prevents water flow to the scrubber head or to the shower head. A second valve selectively flows water to a channel to turn a power disc. A parallel connected scrubber disc has a surface cover with microhook or loop-type fasteners to hold complementary fasteners on an annular scrubber pad. An annular sponge is mounted on a ring on the head outward of the scrubber pad for preventing splashes. The second valve may direct water through the channel and a spray head mounted centrally in the discs or back to the shower head.

Abstract: An apparatus for cleaning a measuring tape, used for measuring the depth of oil in a storage tank and partially immersed in the oil for this purpose, is mounted in the tank beneath a hatch in the top of the tank.

Abstract: There is disclosed a technique for tightening threaded fasteners in which values of offset torque, initial tension rate relative to angle, final tension rate relative to angle and other joint related factors are empirically determined by instrumenting a plurality of fasteners of the type ultimately to be tightened. In one embodiment, torque and angle are monitored during tightening. Calculations are conducted, while tightening, to determine the tension prevailing in the bolt at a particular angle of advance. By using the calculated tension value and the particular angle of advance, an instantaneous position of threading advance on the tension-angle curve of the fastener is established. From this instantaneous position, it is determined how much greater angle of advance or how much torque is required to tighten the fasteners to a final desired tension value. The same technique may also be used merely to monitor tightening which is terminated by a different tightening strategy.

Abstract: A CMOS Process for fabricating channel stops which are substantially formed as a by-product of growing a field oxide is described. A p-type region is formed at an edge (or edges) of an n-type well through an opening in a silicon nitride layer. An oxide is grown at the opening. As the oxide grows, n-type dopant from the n-type well accumulates at the edge of the oxide, forming a more highly doped n-type region. Simultaneously, an adjacent p-type region is formed under the oxide from the p-type dopant. The process also permits easy fabrication of a buried contact to the p-channel device thus eliminating the need for a metal contact when forming a bistable circuit.
