Abstract: Magnetic pins (9) preswaged at an off-center point (1<sub>1</sub>) along their length are assembled into a printed circuit board (7) by energising a pair of electromagnets (1, 3), disposed one above and the other beneath the circuit board, to cause the pins scattered over a template (8) to become erect. This results in some of the pins being disposed with their shanks protruding through the holes in a magnetic plate (5) disposed below the circuit board whilst others of the pins pass through the circuit board but do not protrude below the magnetic plate. Increasing the energisation of the upper magnet (1) causes the non-protruding pins to be ejected from the circuit board. Subsequent deenergisation of the upper magnet (1) results in further pins becoming disposed with their shanks protruding through the magnetic plate (5). The energisation cycle of the magnets (1, 3) is repeated until the circuit board (7) contains a pattern of pins defined by the template (8) with all the pins oriented so that they protrude through the magnetic plate (5).

Abstract: The invention relates to a coolant-flow mixing grid for a nuclear-reactor fuel assembly. 
     The mixing grid, which has essentially no fuelrod supporting function, is composed of straps (44) interleaved in egg-crate-like fashion to define cell openings (46, 60) for fuel rods, each of which cell openings has associated therewith at least one mixing vane (52) disposed on the downstream edge of one of the straps, and at least one impact-preventing protrusion (54) projecting from the side of the strap into the associated cell opening so as to protect the mixing vane associated therewith from impact when a fuel rod therein undergoes lateral motion. The mixing grid includes a peripheral strap (58) to which the interleaved straps (44) are connected and which lends added structural integrity. The inner straps (44) preferably are of substantially lower height than the peripheral strap (58) in order to minimize coolant pressure drop through the grid as well as the amount of structural material capable of parasitically absorbing neutrons.

Abstract: A hydraulically damped mounting device has two anchor points (2,3) joined by a resilient spring (9). The resilient spring (9) and a partition (6) define a working chamber (13) for liquid, the working chamber being in communication with a compensation chamber (14) via a passage (15). The compensation chamber (14) is bounded by flexible bellows (5). A flexible diaphragm (16) defines, together with the partition (6), a gas pocket (18). Relative movement of the anchor points (2,3) causes a change in pressure in the working chamber (13). High frequency vibrations are absorbed by movement of the diaphragm (16) with little resistance to movement. Low frequency vibrations cause liquid movement through the passage (15) with a strong damping effect. This affect may be controlled by suitable selection of the length and diameter of the passage (15). Preferably, a bleed orifice (38) extends from the gas pocket (18) to compensate for thermal changes in the volume of the pocket (18).

Abstract: A surge control system (18) for a compressor anticipates the actual surge condition and initiates anti-surge protection in proportion to the magnitude of the anticipated surge condition. This is done by providing a feed forward signal from a control station (20) to a summing station (48), along with a normally generated surge control line point, to offset this point by an amount determined by the feed forward signal. The offset point is used as an input to a controller (56) for controlling a bypass valve (28) in a bypass loop around the compressor.

Abstract: A system for processing of multifrequency input signals to provide a Fourier transform output is provided which can, for example, partition a wide input frequency band into a number of narrow bands and concurrently detect the presence of one or more signals of different frequency in the input. An array of input wave energy transducers is energized with the broadband signal, and by virtue of progressive shifting of the transducers relative to the propagating medium (such as a surface acoustic wave substrate) generates one or more composite wavefronts dispersed at frequency dependent angles. An array of output transducers are disposed along a focal region, each responding to wave energy within a specific frequency range received at its location due to dispersion of the composite wavefront. Such systems preserve phase coherence while responding to multiple input frequencies, but are compact and mass producible at relatively low cost.

Abstract: 0 in a stop-and-display station (10) in document-handling equipment wherein a document (14) in a track (12) is stopped and viewed through a transparent first wall (20), where- against it is supported by a non-transparent second wall (22), a reflective photosensor assembly (24) is angled relative to the back wall such that a ligh beam (56) from a light-emitting diode (42) cannot be specularly reflected onto a phototransistor (44) either from a document (14) or from the inner surface of the transparent first wall (20). The phototransistor (44) intercepts a portion of the scatter-reflected light (60) from the document (14). The light from the light-emitting diode (42) is modulated with a predetermined frequency, and the output signal from the phototransistor (44) is filtered by a band-pass filter (68) before threshold detection (70) to provide indication of the presence of a document (14). A turn-off delay circuit (72) prevents loss of indication of the presence of a document unless signals from the phototransistor (44) have been absent for longer than a predetermined period. The apparatus resists false alarms of the presence of a document in consequence of extraneous light and extraneous reflections. The turn-off delay circuit (72) prevents marks on the back face of the document (14) inadvertently causing loss of signal (74) indicative of document (14) presence.

Abstract: @ An A.C. Plasma Display Panel is operated in a video mode using the same signal train as applied to a conventional cathode ray tube terminal. For character generation, a selective erase technique is employed in which all cells in a raster line are energised and then selectively erased in accordance with the video data to be displayed. To facilitate the erase operation, a line of cells in close proximity to the scan line being selectively erased is employed to provide adequate and uniform priming for the erase operation, and is synchronised to maintain its position with respect to the line being erased. A short plasma erase signal is utilised to fit within the scan rate of the display. The invention is also applicable to character generation in block or multi-line mode.

Abstract: The press container of a wash press sits on a porous press plate. Because of the high press pressure of the press piston head the fabrics of the wash are partially forced into the holes of the press plate. In order to remove the pressed wash safely from the press plate, the pressed wash is raised somewhat from the press plate when the press container and press piston are simultaneously raised, first into a middle position in which the press piston head remains, while the press container is raised further. The wash loosened in this way can be safely slid laterally from the press plate.

Abstract: A "flying field" computer aided interactive microscopical mapping system has been developed that enables an operator to map over a region of the specimen covering many microscopical fields of view without the discontinuities associated with moving the stage and then generating mapping marks as separate and discrete operations. By fixing the mark generation point at a single location on the display device corresponding to the instantaneous intersection of the microscope's optical axis with the specimen stage, a trail of marks are produced that move in unison with the stage motion to remain superimposed with the viewed live specimen image. The points thus recorded are available for later display and analysis.
