Abstract: The proposed device is a sleeper for railway track systems, suitable for incorporation in the track near points, more particularly near the drives and the associated tip fastenings for the points-tongues, which are adjustable via slide rods. The aim is to replace expensive manual operation by high-tech mechanised track construction using completely mechanised track-tamping machines, even near the points-tongue drive and the associated tip fastenings. To this end, the proposed sleeper is a box sleeper (1), characterised by a steel trough or box-like sleeper section member (5) which has a cross-sectional width (15) and a cross-sectional height (16) matching that of a normal concrete or wooden sleeper and has an open part (31) on top and is optionally closed or closable at its ends by transverse plates (17 and 18) and has laterally projecting bearing flanges (13 and 14) for stock-rail securing means (28, 29), points-tongue slide chairs (30) and/or operating components of tip fastenings, and the trough or box-like sleeper section member (5) is associated with tip fastenings in the form of "latch fastenings" (33) comprising stationary guides (32) and movable latches (34), cam rods (35) and cam-rod bearings (37), all of which project into the upper part (31) of the trough or box-like sleeper section member (5), whereas the bottom part houses the points-tongue slide rods (44), the tongue-monitoring linkage (45), heating rods (43) if any, and shock-absorbing elements (38). The open part (31) of the trough or box-like sleeper section member (5) is closable on top by releasably mounted covers which can be secured e. g. to the bearing flanges (13 and 14) of the trough or box-like sleeper section member (5) of the box sleeper (1).

Title: Method and apparatus for effecting gas-liquid contact
Inventor: SMITH JAMES W
IPC: B01D53/78
Filed: 1993-04-05
Granted: 2001-07-24
Abstract: Components, usually but not exclu-sively gaseous components, are removed in a liquid medium from gas streams and chemi-cally converted into an insoluble phase or physically removed. Specifically, hydrogen sulfide may be removed from gas streams by oxidation in aqueous chelated transition me-tal solution in a modified agitated flotation cell. The same principle may be employed with other procedures in which a gaseous phase is dispersed in a liquid phase to effect an interaction between components present in such phases, for example, to treat or strip or react a component of the liquid phase. A gas-liquid contact apparatus, which may be a combined chemical reactor and solid pro-duct separation device, also is described. In order to effect efficient mass transfer and rapid reaction, gas bubbles containing hy-drogen sulfide and oxygen are formed by ro-tating an impeller at a blade tip velocity of at least about 350 in/sec. to achieve the re-quired shear. To assist in the reaction, a surrounding shroud has a plurality of openings, generally of aspect ratio of approximate-ly 1, of equal diameter and arranged in uniform pattern, such as to provide a gas flow therethrough less than about 0.02 lb/min/ opening in the shroud. In general, the gas velocity index of gas through the openings in the shroud is at least about 18 per second per opening, preferably at least about 24 per second per opening. Each of the openings has an area correspoding to an equivalent diameter less than about one inch.

Abstract: High melting temperature Pb/Sn 95/5 solder balls ale connected to copper pads on the bottom of a ceramic chip carrier substrate by low melting temperature eutectic Pb/Sn solder. The connection is made by quick reflow to prevent dissolving Pb into the eutectic solder and raising its melting temperature. Then the module is placed on a fiberglass-epoxy circuit board with the solder balls on eutectic Pb/Sn solder bumps on copper pads of the board. The structure is reflowed to simultaneously melt the solder on both sides of the halls to allow each ball to center between the carrier pad and circuit board pad to form a more symmetric joint. This process results in structure that are more reliable under high temperature cycling. Also to further improve reliability the balls are made as large as the I/O spacing allows without bridging beam on balls; the two pads are about the same size with more solder on the smaller pad; the pads are at least 75% of the ball diameter; and the eutectic joints are made as large as possible without bridging between pads. For reliability at even higher temperature cycles or larger substrate sizes columns are used instead of balls.

Abstract: A tank interceptor for rain water and waste-water includes a container which has an intermediate partition dividing the chamber into a by-pass compartment above the partition and a treatment compartment below. An inlet is positioned adjacently above the partition and an outlet is also positioned adjacently above the partition, but spaced away from the inlet. The partition includes a raised portion isolating the inlet from the outlet, such that liquid entering through the inlet and seeking to reach the outlet through the by-pass compartment must overlow the raised portion in order to do so. Openings are provided through the partition on the inlet side and the outlet side of the raised portion, and communicate the by-pass compartment with the treatment compartment. The openings are such that liquid, without having to overflow the raised portion, can travel from the inlet to the outlet through thetreatment compartment.

Title: Detection of a low level marshalling sequence
Inventor: WELTON PAUL DOUGLAS
IPC: H04J14/08
Filed: 1995-06-21
Granted: 2000-11-28
Abstract: In a TDMA communications system comprising a base station and a number of outstations, a marshalling signal enables a newly connected outstation to determine the timing of its transmission bursts. A detector circuit for recovering the marshalling signal incorporates comparators (21, 41) whose thresholds are adjusted to the high and low levels of the normal data signal.  The marshalling signal is recovered from one or other of the comparators (21, 41) according to whether a high or low normal data signal is received, this condition being determined by a third comparator (31) whose threshold is adjusted midway between the high and low level. This allows the marshalling signal to be recovered continuously without interrupting normal data transmission from the outstation.

Abstract: A method for manufacturing a semiconductor device in which crystal defects are generated in a semiconductor crystal by irradiating a semiconductor substrate (1) with a particle beam. In the preceding process of the irradiation process, the substrate (1) is heat-treated such that the temperature of the substrate (1) is raised rapidly in ten minutes to 550-850 ~C and maintained for one second to 60 minutes. Crystal defects are generated in the crystal by irradiating the crystal with such a particle beam as an electron beam, the life time of carriers is shortened, and accordingly the switching speed is increased, not lowering the electric characteristics such as the current amplification factor. Thus a semiconductor device having both a high switching speed and good electric characteristics is fabricated.
