Abstract: Apparatus for metal plating an article comprising a frame having a plurality of sealing members positioned thereon, the frame being capable of conducting an electrical current between sealing members, each sealing member being adapted to be in close contact with part of an article to be located thereon, and to thereby substantially prevent fluid from touching that part of the article or entering into a bore or recess of the article, each sealing member further being adapted to conduct current between the frame and the article.

Abstract: An arrangement of an airfoil, such as a main wing of an aircraft, includes a close-mounted engine on a short pylon connected to the airfoil, an inboard slat arranged inboard from the engine pylon along the leading edge of the airfoil, and an auxiliary high lift device. An open cut-out space is formed between the outboard edge of the inboard slat, the engine pylon, and the leading edge of the airfoil when the inboard slat is extended. The auxiliary high lift device is configured and arranged to be extendable into an extended position in which it aerodynamically covers or closes the cut-out space. The auxiliary high lift device is a movable high lift component that can be retracted into a retracted position in which it is recessed and integrated into the outer contour of the engine nacelle and/or the pylon. Thereby, the structural arrangement and mechanisms necessary for extending and retracting the auxiliary high lift device are simplified, and the weight and costs are reduced.

Abstract: The invention relates to a local area network operating in the asynchronous transfer mode, with a first transceiver (1 to 8, 54 to 57) which includes a radio device (33, 60) for transmitting cells to a plurality of other transceivers (1 to 21, 54 to 57). For a data exchange between the first and the other transceivers (1 to 21, 54 to 57) without cells being blocked, a radio device (49, 60) includes a first buffer memory (73) assigned to a respective other transceiver (1 to 21, 54 to 57). A first buffer memory (73) is used for storing a cell whose destination is another transceiver (1 to 21, 54 to 57) which is assigned to the respective first buffer memory (73).

Abstract: A method of identifying an analyte, using a chemical sensor (e.g., a piezoelectric crystal oscillator) which produces an output frequency responsive to different analytes by a characteristic change in the output frequency. The sensor is exposed to a step change (to) in concentration of the analyte and the resulting frequency characteristic measured. An expression for this characteristic is derived consisting of two exponential functions (F, S), one (F) derived from the early part of the frequency characteristic and the other (S) from the latter part. The four parameters (A.sub.2, A.sub.3, A.sub.4, A.sub.5) resulting from the functions so obtained are characteristic of the particular analyte.

Abstract: A loading device primarily for injecting granular plastic material into molding or extrusion machines includes a tee chamber connected to a source of the material. A filter and screen are supported on a top plate interposed between the filter and the tee chamber. A baffle is located in the tee chamber to deflect the solid material to a sight glass assembly, while air and fines flow toward the screen and filter. A second or middle plate is inserted between the tee chamber and the sight glass assembly. A bottom plate supports the sight glass and is part of an end bell which includes a quick connect and disconnect sleeve for attachment to the associated machine. A plurality of support rods and threaded members secure the top plate to the middle or second plate, and the middle or second plate to the bottom plate.

Abstract: Local area network operating in the asynchronous transfer mode (ATM) comprising a plurality of stations which are coupled each via a network interface, which interface comprises a coupling device and a control arrangement and transmits cells via the coupling device between send and receive ring lines, to at least one station and at least one control arrangement. A control arrangement comprises an access controller which is arranged for conveying, in dependence on the contents of the header field of a cell received from the coupling device, the cell or first parts of the cell and/or additional information to a bus system and units coupled to the bus system.

Abstract: A reservoir sight glass assembly forming part of a material transfer system for loading lightweight granular plastic material into injection molding machines and the like is connected to the associated machine and to a light weight pressure relief chamber attached to the reservoir sight glass assembly, both connections being by quick disconnect devices. The reservoir sight glass assembly includes a sensor adjustably positioned against the sight glass which responds to the level of material in the reservoir sight glass assembly and a magnet assembly which traps ferrous contaminants and prevents their entering the machine. The flow of material to the pressure relief chamber is controlled by the sensor which turns a regulated source of compressed air on or off depending upon the sensed level of material in the reservoir sight glass assembly.

Abstract: A reliable pulse source circuit utilizing two independent but synchronized pulse generators is disclosed. The pulse source circuit maintains output pulses even though one pulse generator fails regardless of the failure mode, i.e., whether the output of the failed generator is stuck high or stuck low. A toggle flip-flop responsive to the presence and absence of pulses from the two generators and its own state outputs controls gating circuitry to generate a sequence of output pulses wherein alternate output pulses occur in response to pulses of one generator and the remaining output pulses occur in response to pulses of the other generator, and if either generator fails, all output pulses occur in response to the pulses of the other generator.
