The invention also relates to an apparatus for the controlled delivery of active substances decreasing over the time of use, which has at least one reservoir. At least one active substance to be delivered is active in the technical, human and veterinary medical, cosmetic and pest control sectors.

Abstract: An exit guard system automatically detects movement of a subject along an exit path in an unauthorized direction. A first video camera is positioned for video imaging movement of a subject along the path, while a second video camera images the subject for identification. Multiple video motion detectors operate in conjunction with the first video camera to determine direction of movement of a subject along the path. A CPU operates with the video motion detectors under an exit guard program to provide a watching mode, during which frames of the second video camera are continuously grabbed and saved. Audible and/or visual alarm signaling devices are operated by the CPU in an alarm mode in response to traffic of a subject in the unauthorized direction. A video monitor displays modes of operation of the system, and control devices allow operator selection and control of modes of operation of the system. Remote access to the system for control, monitoring or other purposes is provided by data modem feature.

Abstract: A container for commercial packaging of goods protects against stresses of filling, storage, distribution, merchandising and use of the container. It includes a structural framework and a sheath conforming to at least portions of the framework, which has horizontal and vertical members which define lengthwise and upright structural elements forming panels joined at corners provided by the upright elements. There may be as few as least one lengthwise structural element of each panel with at least one vertical element at each corner. The panels are thus provided with windows therein to provide an essentially skeletonized structure. The structural elements are of recyclable and/or reuseable structural material and configuration as will provide the container with a strength which is at least about 80-85% of the strength of a non-windowed container of such structural material. The sheath has barrier properties to enclose the goods therein in protected relationship.

Abstract: An electrostatically dissipating shoe protects against building up of electrostatic charges by dissipating of such charges through controlled ohmic path leakage between foot and ground. The shoe outsole is formed of synthetic material of substantial resistivity, providing overall resistance across it of about 10.sup.6 -10.sup.8 ohms. A flexible dissipating strip of synthetic material treated to be slightly conductive (about 10.sup.5 ohm-cm) overlies the outsole and extends along a major portion of the shoe length beneath an insole, being secured to the insole by electrically conductive adhesive. At least a heel portion of the insole is apertured over the strip. A cushion layer and/or sock liner overlies the insole, being also of substantial resistivity (e.g., about 10.sup.5 ohm-cm), and secured by conductive adhesive, which also fills the apertures for providing a conductive path through them to the strip. The construction creates an ohmic path continuous between foot and ground having resistance of 10.sup.

Abstract: The combination of a chemical feeder for liquid circulating systems comprising a casing provided with a vertically adjustable weir, and a disposable container for chemicals for treatment of the liquid which container is receivable within the casing. The container is provided with an opening for extension therethrough of the weir to a preselected height consonant with the desired concentration of the solution to be formed. The liquid is introduced into said container from the feeder for dissolution of the chemical with the resulting solution flowing downwardly through the weir for ultimate discharge to the associated system.

Abstract: A composite semiconductor light-emitting display array. Light is emitted and observed through a light-transmissive planar array of LED devices formed in a monolithic transparent single crystal such as GaP. Light is generated at the back of the single crystal, but is observed through the front of the crystal. The crystal with its array of LED's is directly interconnected with a monolithic circuit having circuit elements for energizing the LED devices. The result is a composite sandwich structure with interconnections sandwiched between the LED array and the integrated circuit.

Abstract: A method and apparatus to electrochemically purify gallium is disclosed where a platinum anode is inserted into an electrolytic cell which contains the unpurified gallium as an anode and the purified gallium as a cathode, the platinum anode serving to reduce the gallium ion level in the electrolyte addition.

Abstract: A method and apparatus to improve electroluminescent semiconductor display segments by decreasing the brightness of the "hot spot" located over the light emitting diode and increasing the brightness of the end portions of the segment. These improvements are accomplished by inserting a deflector into the translucent medium directly over the light emitting diode and deflecting, to the segment ends, a portion of the light that would have made up the bright "hot spot.

Abstract: A small portable device quickly secured to and removed from a body of monocrystalline material to be sawed and useful for aligning the body with respect to a saw blade, permitting sawing with precisely predetermined crystallographic orientation. The device has a viewing screen, a light source, and first and second autocollimators. The first autocollimator directs a first collimated light beam toward a surface of the material. The resultant reverse reflection is directed back through the collimating lens and a beam splitter images the reflection on the screen, providing a pattern on the screen characteristic of a crystallographic plane of the material, the pattern position corresponding to the orientation of the device with respect to the crystallographic plane.

Abstract: Disclosed is a method and apparatus to improve the capabilities of automatic and semi-automatic diode, integrated chip, and wafer probers. Prober contact with the upper surface of the wafer to be tested is accomplished through an electronic logic circuit triggered by electrical contact of the probe as opposed to a mechanical sensor. This improved surface position signal is supplied to additional digital logic circuitry to operate a vertical axis control mechanism which precisely locates the probes relative to the wafers that will be tested. Thus, prober contacts with test wafers are positively and accurately made improving the reliability of the test stage of wafer production.

Abstract: In a high temperature solid-solid diffusion process for diffusing impurities into a semiconductor body from a dopant source material, semiconductor surface attack is prevented by the presence of a layer comprising particles of a material substantially inert to the diffusion between the semiconductor body and dopant source material. Uniform deep regions and/or regions of high conductivity can be obtained, if desired.

Abstract: Apparatus for semi-sealed diffusion of semiconductor materials includes a quartz tube with a quartz stopper at one end to facilitate the loading and unloading of semiconductor materials, the other end of the quartz tube having an inlet passage with a quartz stopcock. The stopper includes quartz pressure release valve.The process involves loading semiconductor material to be diffused into the tube with a source of diffusion. The semiconductor material, e.g., in the form of wafers, is first coated with an oxide layer. The stopper is inserted to seal the tube, the interiors being then purged with an inert gas supplied to the inlet passage which is subsequently closed prior to placing the tube in a furnace to initiate the diffusion process. After diffusion, the ampoule is quenched, the stopper removed and the tube unloaded. The oxide layer is then stripped off revealing a diffused, damage-free surface.
