Abstract: Un moteur électrique (50) ayant un palier ferrofluide intégral permet d'obtenir une réduction significative de l'usure, du flux de dispersion et du bruit perceptible par rapport aux moteurs conventionnels utilisant des paliers à billes. Le moteur (50) comprend un moyeu (54) et une base (52) laquelle est fixée à un arbre conique à perméabilité magnétique (58) qui définit une cage de palier intérieure, et le moyeu (54) est fixé à un manchon intérieurement conique, à perméabilité magnétique (78) qui définit une cage de palier extérieure. Des aimants permanents (108) entourent le manchon (78) et peuvent tourner avec ce dernier pour créer des champs magnétiques qui ont une interaction avec l'enroulement du stator (110A-110B) pour provoquer la rotation du moyeu (54) et du manchon (78). De plus, les aimants permanents (108) forment des chemins de flux magnétiques avec l'arbre (58) et le manchon (78) pour maintenir le lubrifiant ferrofluide entre les cages de palier interne et externe.

Abstract: Apparatus for generating shock waves for destruction of kidney stones comprises an upwardly opening ellipsoidal reflector (12). A resilient diaphragm (14) closes the otherwise open end of the reflector (12), and the reflector (12) is filled with water or other suitable liquid. A spark gap (32, 32a) is provided in the reflector (12) at the first focus point thereof, and the reflector (12) is positioned relative to a human body such that the diaphragm (14) presses against the body and the second focus point of the ellipsoid lies precisely on a kidney stone to be destroyed. Electronic apparatus is provided for causing a repeating spark across the gap to generate a series of shock waves which are focused by the ellipsoidal reflector (12) to concentrate on a kidney stone. Gas is released by the sparks, and either a small tube (18) surrounds the spark gap, or a diaphragm (56) immediately overlies the spark gap (32, 32a) to isolate water adjacent the spark gap (32, 32a) from most of the water in the reflector (12). The isolated water is constantly recirculated to flush away gas.

IPC: H04L9/10
Filed: 1987-04-22
Abstract: A method for simplifying key management in situations where unique cryptographic keying relationships are required end-to-end between pairs of parties and a symetric encryption algorithm is to be used. It is useful in cases where the parties come from disjoint subsets of the total population of parties. The method provides some of the characteristics of a public key crypto system (PKS) utilising the public identities of the parties as part of the key, but lacks the property of PKS which allows a party to independently generate a secret key which is known only to that party.

Abstract: A layer of copper foil (14, 16) is etched to a required conductor pattern, coated with a thin layer of uncured fibre-free epoxy polymer, (26, 28) and then another layer of copper foil (22, 24) is placed on top. The sandwich is bonded by heat and pressure which cures the layer of polymer (26, 28). The top foil (22, 24) is etched to form another required conductor pattern which is both electrically insulated from and mechanically adhered to the underlying conductor layer (14, 16) by the layer (26, 28) of cured polymer. These steps are repeated as often as is necessary to build up the required number of layers. Interconnections between different layers are either formed by drilling and plating through holes (30), or by a etching hole in a conductor (222) and then plasma etching through the exposed polymer (226) to the underlying conductor (214) with subsequent metal plating (235) to join the conductors in the different layers. The outermost conductive layer can be formed as physically isolated pads or islands of metal. Connections to and from these pads are through conductors buried in the underlying layer of the polymer.

Abstract: An arrangement for feeding microwave energy from a microwave source (14) to the oven cavity (10 of a microwave oven comprises an elongated groove-shaped recess (16) in one of the conductive cavity walls (17), into which recess (16) microwave energy is fed at a centrally located feeding point (15). At its open side the recess (16) is covered by a rotatable conductive plate (22) arranged very close to the cavity wall (17) so that the recess (16) together with the plate (22) will form a waveguide-like structure. The plate (22) is shaped so that during its rotation time-varying feeding passages between the recess (16) and the oven cavity (10) are formed at both opposite ends of the recess, the passages allowing the transfer of microwave energy from the recess (16) to the cavity (10). These measures result in a very simple and space-saving arrangement of the "dual feed" type.
