Abstract: A plug for the electrical connection of motor vehicle trailers has an inner sleeve (18) and a bayonet connecting part (16) which can be rotated in relation to one another. A locking device serves for locking inner sleeve (18) and bayonet connecting part (16) when the plug is pulled out. The locking device has a resilient element arranged between bayonet connecting part (16) and inner sleeve (18), which resilient element cooperates with a radially protruding part (34) which is moved radially when inserting the plug into a socket. In order to protect the locking device against external influences, it is proposed to allow the protruding part (34) to project through an opening in the inner sleeve (18) in the direction of the longitudinal centre axis of said sleeve. <IMAGE>

Abstract: A device for equalising and demodulating binary continuous phase modulated CPM data signals with a modulation index of 0.5 comprises a baseband converter (10) for generating the quadrature components (I, Q) of a received CPM signal in the baseband and an equaliser/detector (30). Provided between baseband converter (10) and equaliser/detector (30) is a preprocessing unit (20) for carrying out a signal processing which is equivalent to a continously phase-rotating of the CPM signal in the baseband represented by the quadrature components (I, Q) in discrete steps of 90 DEG  per bit interval of the binary data signal contained in the CPM signal. Introducing said preprocessing unit (20), which can be achieved at small expense, makes it possible to use a relatively simple, conventional equaliser/detector for binary pulse amplitude modulated (PAM) signals to equalise and detect binary CPM signals which are distorted when received.

Abstract: There is described a photographic element in which increased exposure latitude is obtained by having a dye-forming coupler in a non-light-sensitive interlayer between two light-sensitive silver halide emulsion layers. One of the silver halide emulsion layers is sensitive to a first region of the spectrum and contains a dye-forming coupler that forms a dye complementary in color to the region of the spectrum to which that layer is sensitive. The second emulsion layer is sensitive to a second region of the spectrum and contains a second coupler that forms a dye complementary to the second region of the visible spectrum. The exposure latitude in the layer sensitive to the first region of the spectrum is increased when the coupler in the interlayer forms a dye complementary in color to the second region of the spectrum, but as a function of development in the first region of the spectrum.

Abstract: In oral radiography, there is a risk of cross-contamination as a result of inserting and removing dental x-ray packets from a patient's mouth. It is desired that the risk of cross-contamination be reduced. Described herein is an arrangement in which a dental x-ray film packet (28) is inserted into a disposable envelope (10) prior to insertion into the patient's mouth. The envelope (10) comprises a pair of flat, substantially rectangular wall members (12, 13) which are joined together along three adjacent edges by means of a heat seal (14). After the x-ray packet has been inserted into the envelope (10), flaps (18, 20) are sealed by means of an adhesive layer (26) applied to at least one of the flaps (18, 20). Once the x-ray packet has been exposed, it can be removed from the patient's mouth and then from its envelope (10) prior to normal processing and development. The presence of the envelope (10) around the packet (28) during exposure prevents contamination of the packet (28) itself by saliva-borne microorganisms.

Abstract: In a digital tape recording system for video and sound signals, in which information in each track is stored in plural sectors having synchronizing preambles that aid in synchronizing the playback of the information, special preambles containing a frequency component that is lower than normal are used for the first sector of the first track in each video frame or field. The normal and special preambles are produced by passing the binary code "...01010101..." (in the case of all but the first sector of each frame or field) or "...011011011011..." (in the case of the first sector) through a Miller Channel Code encoder to produce, in the first case, a synchronizing square wave fluctuating at one-fourth the bit presentation frequency, and in the second case, a synchronizing quare wave fluctuating at one-sixth the bit presentation frequency. Special resonant circuits associated with the playback circuitry detect the special lower frequency component and signal the precise start of a new frame or field. This signal is used for capstan synchronization, head positioning during playback, and head positioning during editing when the record, heads are used as playback heads so that they may be properly positioned to overwrite individual sectors on a track without overwriting other sectors.

Abstract: The described embodiments of the present invention provide a memory cell and method for fabricating that memory cell and memory array including the cell. The memory cell is a trench capacitor type having a transistor (1-1-2) formed on the surface of a major face of a substrate (16) and having a capacitor (2-1-2) formed in the substrate around the periphery of a trench. The capacitor and transistor are connected by a buried, heavily doped region (26) having the opposite conductivity type from the substrate. A doped storage area (24) having the same doping type as the buried doped region surrounds the trench. A field plate (30) is formed in the trench separated from the storage region by a dielectric layer (32). The field plate extends onto the isolation areas between memory cells thus providing isolation between cells using a minimum of surface area. A self-aligned process is used to form the source (14) and drain (12) for the pass gate transistor and automatic connection between the source of the transistor and the buried doping layer is made by the buried N+ layer. A sidewall silicon nitride passivation filament (38) is formed to protect the sidewalls of the interlevel insulator region between the first (30) and second (3-3, 3-4) polycrystalline silicon layers.

IPC: C08J9/40
Filed: 1990-06-23
Abstract: A method of improving the flame resistance of foams, such as open cell polyimide foams, through the introduction of finely divided metal oxide particles into the foam cells. A stable water suspension or gel is prepared using particles of metal oxides, such as aluminum oxide and silicon dioxide. An opacifier such as titanium dioxide may also be added. An open cell foam product is placed in the gel until the cells fill with the gel. Excess gel is removed and the foam is dried, leaving the metal oxide particles trapped in the cells. If desired, the foam may be post treated, such as by compression at the stabilizing temperature, resulting in a densified foam which further mechanically traps the particles.

Abstract: The operating reliability of an H2/O2 fuel cell battery whose positive electrodes are arranged to form consecutive groups with parallel gas supply (the so-called cascade arrangement) is increased by providing H2/O2 recombination devices in the gas path at junctions between one electrode group to the next. Hydrogen which has entered the oxygen cascade and which cannot otherwise be reacted in positive fuel cell electrodes containing O2-specific catalysts and acts like an inert gas on the latter can be removed at said recombination devices. Additionally equipping the recombination devices with temperature sensors makes it possible to monitor the operation of the system. The recombination devices can be cooled by heat exchange with the electrolyte or cooling water circuit and can be dried by steam exchange between the gas flow and the liquid flows using a hydrophobic partitioning membrane.
