Abstract: In the parallel processing computational apparatus disclosed herein, a switching network employing both routing switch elements and concentrator elements efficiently couples bit serial messages from a multiplicity of processors to a multiplicity of memory modules. The apparatus operates in a highly synchronous mode in which all processors issue memory requests only at essentially the same predetermined time within a frame interval encompassing a predetermined substantial number of clock periods. The routing switch elements and concentrator elements incorporate means for comparing the addresses of requests which may be blocked at any element with requests which get through and, if the addresses are the same, returning the memory response to all processors seeking the same memory location.

Abstract: A low profile remotely controlled carriage (31) which is inserted between the rotor (5) and stator (7) of an electric generator (1) carries an impactor which can be preloaded to strike the stator wedges in all orientations around the stator (7) with a selected high impact force which causes the stator wedge to vibrate. A detector seismically isolated from the impactor measures the deflections in the vibrating stator wedge (25). Preferably, the detector includes an eddy current coil (13) positioned to measure the distance to a wedge follower which vibrates with the wedge. In one embodiment, the wedge follower is a vacuum cup secured to the wedge. In another, the eddy current coil measures the distance to a foot spring biased against the vibrating wedge. Preferably, the detector is seismically isolated by mounting it on a separate carriage disposed in an aperture in the low profile carriage (31).

Abstract: A holder for a molten metal sampling device includes a pipe (12) having a guidance chamber (18) in a lower portion and a molten metal sampling device (14) in an upper portion. The pipe is open downwardly and a closure element (24) closes the opening. The closure element has a density such as to cause it to float upwardly in the molten metal being sampled. A protective cover (40), preferably of two parts (42), enoloses the closure element and a lower portion of the pipe. A retaining device such as a spring clip (46) holds the separate parts of the protective cover together around the closure element and the lower part of the pipe. The retaining device is adapted to fail upon contact with the molten metal, thus releasing the portions of the protective cover so that they will separate and float upwards, whereupon the closure element also separates and floats away, allowing molten metal into the guidance chamber and the sampling device.

Abstract: In a VTR for TCI signals, horizontal synchronizing signal with different time width is inserted for identifying the chrominance signal component multiplexed in each recording line at the time of recording. At the time of reproduction, this horizontal synchronizing signal is separated to generate a signal identifying the chrominance signal component in the corresponding recording line. The chrominance signal sequence in the reproduced TCI signal indicated by the identification signal and the proper sequence of the chrominance signal process are compared, where both sequences are made to coincide with each other when there is discrepancy between both sequences to prevent the generation of hue error on a monitor.
