Title: Video selection and distribution system.
Inventor: FENWICK ROBERT B
IPC: H04N7/173
Filed: 1990-04-19
Abstract: A video distribution system transmits selected video programs to a number of independently controlled video monitors. The video monitors are arranged in groups, each group being coupled to a distinct transmission medium. A program selector associated with each video monitor generates video connection requests which specify a video source to be connected to that video monitor. A two stage video switch apparatus couples specified video sources to specified video monitors. The first stage routes specified video signals from the video sources to the second stage, which is a frequency multiplexer. The frequency multiplexer then transmits the specified video signals for each group of video monitors in distinct frequency bands on one of the transmission mediums. Each video monitor within each group of monitors has a tuner that is tuned to receive the video signal in a distinct one of the frequency bands. In effect, the transmission medium for each group of video monitors has a separate transmission channel for each of the monitors in the group. Finally, the system has a controller which receives the video connection requests, and controls the video switch apparatus so that it couples specified video sources to specified video monitors.

Abstract: Fasteners, which are used for fastening high loads, are anchored in the drilled hole by means of an expanding body which is drawn into an expanding sleeve. If high instantaneous loads occur on the fastener, for example because of earthquakes, there is a risk that the fastener may break out of the drilled hole. 
<??>In order to ensure that the fastener continues to retain its retention function, even after the occurrence of high excess stresses, the inner hole 14 of the expanding sleeve 11 has a first cylindrical section, which originates from its front end and corresponds approximately to the length of the expanding cone 5 of the expanding body 6, having a diameter corresponding to the smallest diameter of the expanding cone 5. Adjacent to this first section is a second, conically expanding section, which continues cylindrically at its maximum diameter. In addition, the longitudinal slots 12 end in the conically expanding section of the inner hole.

Abstract: For the controlled large-scale production of a uniform and firmly adhering brown covering layer (brown patina) on surfaces of semifinished copper products, especially on rolled strip or sheet for the building sector, the process according to the invention provides for first roughening the surface of the semifinished copper product by mechanical treatment and then subjecting the semifinished copper product to a heat treatment for a period of 0.1 to 30 minutes at a temperature within the range from 150 to 650 DEG C. 
<??>This method makes it possible to provide semifinished copper products preweathered in the works, without having to wait for the brown surface discolouration which depends on the long-term action of atmospheric influences. 
<??>For a further improvement in the adhesive strength of the brown patina, the semifinished copper product can advantageously also be subjected to a chemical further oxidation after the heat treatment.

Abstract: The present invention concerns a device for connecting and disconnecting electrical connectors. 
     The device consists of latches (9) which are pivotably arranged in the lower and upper corner regions of a protection housing (6) and a card (3), respectively, and flexible elements (15), in particular springs, which are fixed to an inflexible catch bar (13) or to housing (1) directly. The flexible elements are provided with cams (30). 
     The latches (9) are associated with the flexible elements (15), comprising the cams (30), such that latches (9) are capable of engaging the cams only after an electrical connection has been made. The position of the cams (30) determines the magnitude of the insertion force for the connector. 
     After connection has been establised, the pressure occurring between the connector elements is largely reduced by the flexibly retreating element (15) with the cams (30). As a result, the device according to the invention allows linking connectors with a very large number of contacts, without connector elements and in particular the board or card being damaged by the insertion force.

Abstract: A system (10) for providing multi-paned glazing lights (16), primarily for use as insulated glazing units in door and windows, employs noble gases for filling the insulative spaced enclosed between the glazing panes. The system (10) uses the glazing light or lights (16) as a gas flow manifold, mounted within a sealed vacuum chamber (12), for evacuating the chamber (12) and the one or more glazing lights (16) located therein. The glazing light, or lights (16), then also serve as the gas flow manifold for filling the lights (16) and the surrounding exhausted chamber (12) with the required noble gas. The system (10) operates at room temperature, and enables selection of the internal pressure of the noble gas within the glazing units, in accordance with predetermined factors such as the altitude of the ultimate site where the lights are destined to be used. The lights (16) are sealed off within the vacuum chamber (12), prior to removal therefrom, while in a controlled environment. The system enables consistent, extremely high gas fillings such as 97% noble gas, in a relatively rapid, economic and ecologically conservative manner.

Abstract: Disclosed is a device for determining an angle of incident light or a shift in incident light based on the output value of a detector. In a predetermined angle detection range, a beam of light incident on a detector for detecting the intensity of light incident thereon is restricted such that the amount of light continuously increases or decreases in accordance with the angle between an optical axis of the incident light and a referential axis of an exposure apparatus. Outside of the predetermined angle detection range, the amount of light is restricted depending on the direction in which the optical axis of the light is shifted from the angle detection range. The amount of light incident on the detector continuously increases or decreases in accordance with the angle between the optical axis of the incident light and the referential axis when the light is made incident within the angle detection range by means of the light restriction means. It is therefore possible to determine the angle of the incident light from the output value of the detector. When the light is made incident outside of the angle detection range, and since the amount of incident light is restricted in accordance with the direction in which the light is shifted, it is possible to determine the direction in which the light is shifted.

Abstract: The genes (sod) encoding Bacillus stearothermophilus and Bacillus caldotenax Mn-superoxide dismutase have been cloned in Escherichia coli and their entire nucleotide sequences determined. With the exception of the post-translationally cleaved N-terminal methionine residue, the predicted amino acid sequence of the B. stearothermophilus enzyme (BSMnSOD) exhibits 100 % similarity to the previously determined amino acid sequence. The B. caldoenax enzyme (BCMnSOD) differs by two amino acids from BSMnSOD. Both recombinant MnSOD's were shown to be functionally active in E. coli, both in vitro and in vivo, and were expressed to 47 % of the cells soluble protein by coupling their transcription to the E. coli trp promoter. The pharmaceutical use of these bacterial superoxide dismutases is described.
