Abstract: A personal locator transmitter adapted to be worn on the wrist and having the size and appearance of a conventional wrist-watch. This transmitter is provided with a programmable memory, a transmitter controlled by the memory, an antenna for reliably radiating signals from the transmitter regardless of orientation of the wrist of a user and including both a manually operable alarm activated by pressing a button, and an automatic alarm actuated by an attempt to remove the unit from the wrist of the wearer. The unit is controlled by a control memory comprised of an EEPROM encoded with unique identification codes and other information as required in the specific application.

Abstract: A simulated brick wall in new or renovated construction utilizes the wallboard normally applied or already in place in such cases in combination with a plurality of birck-simulating boards and a material which simulates mortar. Each of the brick-simulating boards is elongated and has a pair of opposite front and rear surfaces, a pair of opposite end surfaces and a pair of laterally-spaced longtudinal opposite side surfaces extending between and interconnecting the front and rear surfaces and the opposite end surfaces. The side surfaces extend in opposite inclined relationship to the front and rear surfaces so as to provide the board in cross-section with a trapezoidal configuration wherein the front surface is wider than the rear surface. Each brick-simulating board has a plurality of spaced apart grooves defined in its front surface and extending between its side surfaces such that the front surface simulates the appearance of a row of spaced bricks.

Abstract: The present invention is directed to a method of chemical addition to a microbial population to condition the population to (i) enhance bioconversion or biodegradation of a given substrate, or (ii) survive and perform greater bioconversion of a substrate when the population is exposed to fluctuating and in particular shock loads of the substrate. The method comprises conditioning the population by exposure of such to a non-toxic or non-inhibitory amount of a material which is biochemically or structurally similar to the substrate in question. The method is applicable in systems where the production of useful metabolites is the objective, as well as in waste treatment where degradation of a waste into more acceptable form is to be achieved.

Abstract: Spring mechanism for biasing a visor-type lid of a cassette includes a coil spring which fits around a pin that journals the lid to the cassette. One end of the spring has a bent portion which is compressed into a well formed in the cassette such that the tip of the bent portion digs into a surface portion of the well and thus resists removal.

Abstract: One broad wall of a recording cassette has a recognition hole which is covered by a breakout tab (here called a "removable piece"), and there is a chamber projecting from the other broad wall of the cassette such that a punch which dislodges the removable piece permanently wedges it into the chamber.

Abstract: A readily adjustable machine which continuously produces corrugated flexible metal tubing from very light gauge metal and of various diameters. A warping ring receives therewithin a longitudinally corrugated narrow strip of formable metal of light gauge and warps the same helically to produce convolutions by means of a helical warping surface which extends into one of the longitudinal corrugations. The size of the tube produced can be varied by merely substituting a warping ring of a different size. A uniquely shaped pair of die-forming rollers have lock-seam forming surfaces which are adjustable relative to each other to provide variation in the degree to which the seam will permit and withstand axial torque. The lock seam is constructed to be symmetrical about the neutral axis of the corrugation and about the slope line of the common corrugation leg of adjacent convolutions which it constitutes.

Abstract: Reaction torque of a planetary gear type torque multiplier assembly is measured in apparatus which includes multiple stage torque multiplying apparatus and a torque readout meter which is operated by the reaction torque sensed. A reaction coupling arrangement operatively associated with a planetary torque multiplier includes a ring gear around which the planetary gears traverse. The ring gear is attached to a pivotable reaction torque cup. The reaction torque cup is biased by a pair of parallel extending deflection beams. As torque is applied, the ring gear deflects in accordance with reaction torque, and the amount of deflection is operatively coupled to the torque readout meter where an indication of torque is registered. The torque readout meter includes a stay set feature to maintain torque indications after the applied torque is terminated.

Abstract: Reaction torque between a drive shaft of a drive motor and the stationary housing of the drive motor is measured by apparatus which includes a torque readout meter and a torque multiplying arrangement. The apparatus includes a pivot sleeve member which is operatively connected to and pivots with the drive motor housing. A single deflection beam extends from the sleeve to the housing of the apparatus. The beam deflects when the sleeve pivots under the application of torque from the drive motor. The amount of deflection of the beam is operatively coupled to the torque readout meter where an indication of torque is registered. The torque readout meter includes a stay set feature to maintain the maximum readings after the applied torque is terminated. Two output shafts supply output torque. One output shaft applies multiplied torque and reduced rotational speed as compared to the other shaft which is directly connected to the drive motor.

Abstract: Hinge for two-part, double-wall plastic box. A spine-like projection extending along the rear of the base of the box terminates in hinge pins which fit into holes in the cover as in the prior art. In the novel box, the spine-like projection consists of two spaced spines, and another spine-like projection at the rear of the cover fits into the spacing between those spines to provide two additional hinge points.

Abstract: A rectangular plastic box for storing video cassettes which includes an unobtrusive hook portion by which the box may be hung on a horizontal member received through a recess in the box. The box also includes a handle portion along its edge opposite the hook which can be stored in a recess from the outer surface of the box, and can be swung out and manually engaged to facilitate carrying the box, or hanging it on or removing it from a horizontal member.

Abstract: Latch for a hinged plastic box wherein a flexible plastic slide fits around the shoulders of a T-shaped rail projecting from the cover part of the box. A tab projecting from the container part of the box fits into a notch in the rail, after which the slide is moved along the rail to latch the cover part to the container part. A detent on the slide then is snapped into place against the rail to provide second latching action.

Abstract: A case for storing a magnetic tape cartridge has a housing, a bias means that opposes movement of a cartridge or a drawer adapted to receive a cartridge into the housing and a latch means for engaging the cartridge or drawer to releasably retain it in the housing. The bias means is positioned near one end of the housing to serve the dual function of pivoting the cartridge or drawer into a latched condition when fully inserted in the housing and also moving the member or drawer toward an open position when unlatched.
