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: An integrated, at least substantially self-contained and at least substantially closed-loop combustion process and system for the control of gaseous, ionic, colloidal, liquid or particulate matter, particularly noxious contaminants contained in the off-gas of a combustion unit, the system comprising a:(a) chemical treatment chamber;(b) a reactant source communicating with the treatment chamber and adapted to provide reactant chemicals in contact with the off-gas;(c) a reactant chemical selector associated with the reactant source;(d) a control device communicating with the off-gas within the combustion system for analyzing the off-gas and actuating the selector in response to the analysis to provide reactant chemicals for contact with the off-gas;(e) an expansion chamber communicating with the treatment chamber and adapted to provide a reduced pressure region of treated off-gas received from the treatment chamber means;(f) an exhaust port in the expansion chamber for discharging the off-gas, and(g) cooling me

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.

Abstract: The security of articles, and particularly articles in transit, is checked by detecting the status of a magnetic strip attached to the articles at a strategic location when the strip is subjected to an electromagnetic field which causes the strip to substantially saturate magnetically, the status of an improper strip, that is to say, a strip whose electromagnetic properties differ from those of a proper strip as a result of physical modification or disparity, being reflected in the nature of the electromagnetic field emanating therefrom, detection of the status of that field providing an indication of whether the strip is proper or not. The same principles can be applied to the coding of articles for validation of identity or authenticity.

Abstract: A semiconductor package houses a single two terminal semiconductor component. The package is hermetically sealed and is adapted for surface mounting. The package consists of an open ceramic box that has slots for external leads. A glass seal provides the means for sealing the leads to the ceramic box. The semiconductor element is in a die form and one terminal is directly bonded to one of the external leads. The other terminal is bonded to a clip that in turn is bonded to the other lead. A lid is sealed to the top of the ceramic box to provide the hermetic seal.

Abstract: Means are provided for removably mounting an ornamental element to the temple piece of an eyeglass frame. In one set of preferred embodiments, a recess which receives the temple piece is defined between the element and a part. One or more machine screws are employed to secure the element on the temple piece. The orientation of the element is determined by a surface which cooperates with the temple piece. In a second set of preferred embodiments, a part with a screw receiving aperture is received in an opening or slot which has a second screw receiving aperture associated with it. A machine screw is received in the aligned apertures to secure the element to the temple piece.

Abstract: When in use on a chair, sets of strings which extend from the seam proximate an expandable pocket are tied around vertical elements of the chair back to secure the cushion. The strings are stored within the pocket when the product is used as a decorative pillow. The pocket material matches the material of the side wall and may be similarly pleated, so as to be visually unobtrusive. The product saves space and money because it can be used as a decorative pillow or a seat cushion, as needed.

Abstract: A powered machine for inserting an attachment member having a filament with a head at one end through an opening in an article and including a needle which is projected from machine in order to penetrate that article and convey the filament head therethrough, in which the needle is cleaned during each actuation thereof by being wiped and/or having a jet of fluid blown across it, and in which the machine is provided with structure for grasping a tag which is to be penetrated by the needle, holding the tag in position while the needle penetrates it, and permitting the release of the tag after the fastening operation has been completed, all with positiveness and facility of manipulation.
