Abstract: A baggage inspection system utilizing fluoroscopy of baggage pieces and the like, employing an X-Ray flash unit, a television pick-up unit for scanning the X-Ray image, storage of the television image and subsequent image reproduction by a television monitor, in which, in accordance with the invention, the memory is a digital solid state memory for the digital storage of a half frame, of an interlaced video frame of the television pick-up unit, with a capacity of 6 to 8 bits per image-point of the image signal to be stored.
Abstract: An apparatus for inspecting or screening articles, such as closed luggage and parcels, having a moveable shield to enclose selectively a monitoring duct area in which the articles are placed for screening by X-ray or similar radiation. The shield moves in a fixed housing (which may in turn be mobile) on wheels. A linear drive motor has a stator fixed in the bottom of the housing. The shield carries a rail electromagnetically reactable directly with the stator. Proximity switches in the housing activated by a magnet on the shield control the travel of the shield. A switch located between the end of travel switches may be employed to vary the speed of the linear motor to provide quick, safe cycling of the apparatus.
Abstract: A gas discharge lamp, particularly useful as a flash tube, has a glass tube and electrode feed-through conductors which are connected with the glass tube in gas-tight relationship via glass members and glass solder. The glass members consist of prefabricated shaped parts having a geometry which absorbs thermal stresses between the glass members and the glass tube.

Abstract: The invention relates to a "warm light reflector", which reflects infrared radiation and absorbs visible light. More specifically, a reflecting layer of, for example, gold carries a double layer of PbS, which is constructed of one smooth layer and of one fine-flocked layer of agglomerates.The disclosed warm light reflector finds particular application in infrared measurement technology, preferably in a passive infrared alarm generator.
Abstract: A photosensitive matrix having a substrate with a group of row conductors, a group of column conductors extending across the row conductors to form a plurality of points of intersection with a photoconductive cell in series with a rectifier adjacent each point to inteconnect the row conductor to the column conductor characterized by the substrate being of a material which is at least approximately light impermeable in the light-sensitive spectrum of the photoconductive cells so that light projected on one cell is not conducted by the substrate to create a false signal in adjacent cells. Preferably, the substrate is a ceramic material which has been dyed black and the dyed black ceramic material consists of Al.sub.2 O.sub.3 mixed with Fe.sub.2 O.sub.3.
Abstract: A luggage inspection apparatus utilizing fluoroscopic examination in conjunction with an X-ray generator, with the fluoroscopic picture being received by a TV camera, the video signals of which are supplied to an intermediate store for ultimate supply to a TV monitor, the camera containing an AC line-coupled pulse generator for synchronizing the camera and the X-ray flash generator, which pulse generator is electrically interconnected with a synchronizing unit which, upon the initiating of a starting pulse, thus likewise synchronously triggers the X-ray flash generator with respect to the AC supply line.
Abstract: An impulse discharge lamp comprising a gas-filled hollow-cylindrical discharge receptacle, whose ends are sealed, vacuum tight, by respective electrodes, which are of disc- or cup-shaped configuration, and have an external diameter which is slightly less than the initial internal diameter of the discharge receptacle, with the electrodes having their peripheral edges rigidly secured, at the outer ends of the discharge receptacle to the internal surfaces thereof, and method of making the same.
Abstract: A baggage inspection apparatus utilizing an X-ray generator for fluoroscopic examination of luggage and the like in which an X-ray detector is disposed in the beam path of the X-ray generator, operative to control switch means for switching off the high voltage of the X-ray beam generator in the event the intensity and/or duration of the X-ray radiation exceeds a predetermined value.
Abstract: A circuit arrangement for igniting flash tubes, without using an ignition electrode, and having two main electrodes which are supplied with an ignition pulse parallel to a flash capacitor and an electronic switch, employs an electronic switch which also constitutes a gas discharge path. In particular the electronic switch may be realized as a flash tube.
Abstract: A manipulatable read-only memory, particularly a punched card read device, having conductor paths comprising row and column conductors, disposed in a matrix formation in the manner of a cross-bar distributor, adapted to be operatively connected at their respective intersections by a corresponding photo-resistor and a rectifier containing a blocking contact, which are connected in series with the blocking contact being formed directly on one of the two conductors.
Abstract: A light-sensitive target for a color television system which includes a transparent carrier plate such as the front plate of a color television camera, having discrete strips of interference filter material disposed thereon. The strips are disposed in parallel relation on the inside surface of the transparent carrier. An intermediate layer is formed over these strips to eliminate abrupt or sharp edges presented by the strip to the inside surface of the tube. A conductive layer is formed over the intermediate layer and finally a light sensitive medium is disposed over the entire inside surface of the system. By means of the intermediate layer, the contour between the light-sensitive and the conductive layers are caused to have generally rounded configurations, thereby eliminating interferences.
Abstract: A pulse discharge lamp, in particular an electronic flash tube, includes a substantially cylindrical discharge tube which, at each end, has an electrode which serves as a cathode or anode and which may be mounted on a lead through pin. Each electrode is constructed such that there is substantially uniform interval between the electrode and the discharge vessel wall radially of the electrode. On the external wall of the tube a longitudinal wire, strip coating, transparent coating or the like is carried as an ignition electrode and extend substantially along the interval between the other mentioned electrodes. At least one of the electrodes, or its mounting, has a metal band attached thereto, bent and spread in such a fashion that its distal end lies at a shorter distance from the ignition electrode than the electrode which supports the metal band.
