Patent EP-0507799-A1 (EP)
Inventor: PIDGEON REZIN
IPC: H04B10/155
Filed: 1990-11-21
Abstract: An optical communications system including a plurality of modulated radio frequency carriers which span more than an octave in bandwidth. In one implementation, the carriers are grouped into ranges which span less than an octave in bandwidth and the individual groups are transmitted over unique optical links. In another implementation, the groups are multiplexed on one optical link by using different wavelengths. In still another implementation, several of the bands are up-converted to the highest band of interest and then transmitted, either over single or multiple links. The resulting optical signals are demodulated and then down-converted before they are recombined into the broadband signal in excess of an octave in bandwidth.

Abstract: A process for separating optical isomers in a pseudo-moving bed system, which comprises introducing a solution containing an optical isomer mixture and a desorbing liquid into a packed bed containing an optical resolution packing therein and having front and rear ends thereof connected to each other endlessly via a fluid passage to circulate a fluid unidirectionally and at the same time drawing out a solution containing one of the separated isomers and another solution containing the other isomer from the packed bed, wherein a port (13) for introducing a desorbing liquid, a port (14) for drawing out a solution containing a readily adsorbable optical isomer, i.e. an extract, a port (15) for introducing a solution containing an optical isomer mixture, and a port (16) for drawing out a solution containing a difficultly adsorbable optical isomer, i.e. a raffinate, are arranged in the packed bed in this order along the direction of fluid flow and the positions of these ports are successively moved in the direction of fluid flow in the packed bed intermittently. The industrial effect of this invention is remarkably excellent, because this process allows an optical isomer mixture to be separated continuously and efficiently, works well even with a reduced amount of a desorbing liquid used, and can deal with a large amount of optical isomers.

Abstract: L'invention se rapporte à un outil de forage descendant, qui est conçu pour creuser un trou à l'avant d'un tubage trainant (15). Cet outil de forage comprend un trépan pilote central (12) et un alésoire (14), ainsi qu'un guide (17; 17'; 17''; 17'''; 17'''', 37) servant à guider l'outil de forage et le tubage (15) l'un par rapport à l'autre, et un arbre (11; 11'; 11''; 11''') destiné à être relié à un marteau perforateur descendant (23). L'invention se rapporte également à un guide et à une unité monobloc en soi. Dans les outils de forage connus du type mentionné ci-dessus, le raccord fileté, par exemple entre le guide et la partie soutenant l'alésoire, constitue le point faible. Pour éliminer ce problème, la présente invention propose une conception structurelle d'un outil de forage du type en question qui évite les raccords filetés dans les parties de l'outil de forage qui sont soumises à des forces de flexion élevées. La présente invention se caractérise en ce que l'arbre (11; 11'; 11''; 11''') et le trépan pilote (12) forment une unité monobloc et en ce que le guide (17; 17'; 17''; 17'''; 17'''', 37) est monté amovible sur l'arbre (11; 11'; 11''; 11''').

Abstract: Water softening is achieved by a combination of electrodialysis and calcium carbonate precipitation. The hard feed water or alternatively recycled soft water is rendered alkaline and is then subjected to a treatment by which precipitation of calcium carbonate is induced. One way of bringing about such precipitation consists in passing the alkaline water across a cake of calcium carbonate crystals having a size not exceeding 100 microns, deposited on a filter (43) and being in an at least fifty fold excess over the amount of calcium carbonate to be precipitated.

Abstract: Safety equipment is disclosed comprising a three-phase heat pipe for the protection of apparatus from exceeding maximum or minimum safe working temperatures. The heat pipe has a working fluid selected so that it will not function below the desired temperature. A working fluid which has a melting point slightly above the minimum safe temperature of the equipment to be protected is preferred for protecting equipment from exceeding its minimum safe working temperature. This heat pipe may be used to cool an apparatus to a temperature where the heat pipe automatically stops functioning and keeps an apparatus from exceeding its minimum design temperature. A working fluid which has a melting point slightly below the maximum safe temperature is preferred to keep equipment from exceeding its maximum safe working temperature. This heat pipe will be inactive at normal operating temperatures but will release excess heat to cooler surroundings before safe working temperatures are exceeded. Transfer may also be by capillary action in a heat pipe having a wick.

Abstract: A moulding apparatus includes a rotatable sprue bushing (10, 30, 40) mounted in mould halves (2, 3) and formed with a sprue therein for introducing material into a mould cavity (8, 39, 49). The sprue communicates with a gate, as an outlet of the sprue, located at a position radially displaced from a centre axis (α) of the sprue bushing. Since the sprue bushing is rotated by a ring gear (13, 34, 33) driven by a motor provided in or beside the mould half, the gate (17, 35, 46) of the sprue rotates around the centre axis when molten resin is introduced into the mould cavity (8, 39, 49), and therefore, the moulding apparatus can eliminate localization of stress in moulded articles, thereby improving quality of the moulded articles.
