Abstract: A water diverter assembly is mounted between the supply pipe and showerhead. It includes an inlet passage and outlet passage connected by a bypass valve. A remote pump is connected by inlet and outlet hoses between the inlet passage and the outlet passage, respectively. A pressure sensitive switch actuates the pump only when water pressure above a preset level is sensed at the supply pipe. The water pressure at the shower head is controlled by the bypass valve.

Abstract: The lens sections of the sunglasses are joined by a spring mechanism. The mechanism includes first and second concentric tubular members. Each member is affixed to the rim of a different one of the lens sections. The members enclose the spring which urges the lens sections toward each other, such that prongs mounted on the rims can engage an eyeglasses frame to mount the sunglasses thereon.

Abstract: To ensure bulk breakdown when the mesa diode with a positive bevel angle is reverse biased, the diffused region is formed with thinner edge portions. This eliminates corner or edge effects which create conditions of high electric field, resulting in decreased breakdown voltage and clamping voltage levels. The edges of the surface of epitaxial region are covered with a narrow oxide layer prior to diffusion. The middle portion of the surface remains uncovered. Diffusing through the oxide results in a diffused region which is thinner along the edges of the device than in the interior region below the exposed surface portion. The oxide thickness controls the depth of the edge diffusion.

Abstract: A system for monitoring the occurrence of an event occurring with respect to an essentially metallic enclosure such as a truck body, e.g., the unwarranted opening of a locked door to the enclosure, which comprises a detector within the enclosure which senses the occurrence of the event and radiates a spread spectrum signal which is readily received by an external module mobile relative to the enclosure, so that the enclosure, at any time during its active life, may be externally interrogated to ascertain whether any such event has occurred, the enclosure optionally also containing a separate unit which records the spread spectrum signals for subsequent display and analysis, whereby the security status of the enclosure may be externally monitored at will, thereby to indicate whether or not the enclosure has been tampered with and, optionally, its security history--when and how frequently the event has occurred--may be retrieved.

Abstract: A substantially closed-loop system for use with a furnace wherein a fuel is burned and produces an off-gas, which system, by sensing appropriate parameters of the off-gas as it passes through the system, treats that off-gas in an optimized fashion in order to substantially eliminate the escape of contaminants and produce a substantial amount of useful by-products by one or more of (a) controlled treatment of the off-gas chemically and physically by employing a multi-flue compartmented and appropriately controlled treatment means, (b) the subsequent conversion of the essentially gaseous effluent from that treatment means into useful by-products, and (c) the subsequent conversion of the essentially non-gaseous effluent from the treatment chamber into useful by-products.

Abstract: A negative resistance weightlifting apparatus suitable for use with, among other things, a weight in the form of a separate barbell, in which means under the direct control of the user controllably produces a negative resistance effect by pressing down with an adjustable force on the weight as it is being lowered and preferably positively disengaging itself from the weight when the latter is being lifted, safety means being provided to adjustably limit the weight locations where such force can be applied and to automatically release the excess downward force when the weight has achieved a predetermined and adjustable lower position, all to produce weight lifting and lowering excercises of maximum efficiency and effectiveness while at the same time protecting the user against accidents and any unfortunate consequences arising from temporary physical weakening.

Abstract: Significant reduction in the cost of fabrication of shallow junction, Schottky or similar semiconductor devices without sacrifice of functional characteristics, while at the same time achieving the advantages is achieved, after the non-polishing cleaning step is essentially performed, by subjecting the substrate to conditions which move disadvantageous factors within said substrate into a space substantially at said surface, followed by substantially removing said factor-containing space from said substrate chemical removal step, followed etching and vapor deposition steps. Although these new steps add time, and therefore cost, to the overall process, the devices under discussion when produced by known industry processes require yet more time, and involve yet more expense, so that the total process represents a substantial reduction in the cost of their manufacture while producing devices which are the equivalent or superior in electrical performance to such devices which are made by known industry processes.

Abstract: A tape is adapted to be secured to a container or other object which when removed therefrom causes the display of a message which was formerly not visible, such as a notification that the object has been tampered with, the tape being provided on one surface with an adhesive layer so that it can be attached to the object and provided on its opposite surface with a release layer so that it can be wound upon itself and readily dispensed without having to remove a protective liner therefrom, the message displayed by the tape both when initially secured to said object and after removal therefrom being located on said one surface of said tape, whereby said tape may be readily and inexpensively manufactured and readily dispensed from appropriate mechanical equipment in large quantity applications.
