Title: Dispositif dote d'un rotor et d'un stator
Inventor: DE VADDER PAUL
IPC: H02K41/06
Filed: 1999-08-05
Abstract: L'invention concerne un dispositif de compression de fluides ou de refroidissement équipé d'un rotor (1) dans un chambre de rotor (2) logée dans un rotor. Le rotor fonctionne selon un mouvement cyclique formé d'une composante de rotation (φ) et d'une composante de translation (T). Le rotor présente un organe de génération d'un champ magnétique de rotor et le stator présente un organe (3) de génération d'un champ électromagnétique de stator s'étendant dans la chambre de rotor. En cours d'opération, le champ électromagnétique de stator crée un champs de forces exercées sur le rotor, chammp qui est asynchrone avec le mouvement du rotor. Le champ de forces comprend une composante de rotation et de translation. Le champ de stator est généré, de préférence, par des électro-aimants qui peuvent être couplés et découplés par magnétisme.

Patent CA-2001586-A1 (CA)
IPC: G02B7/04
Filed: 1989-10-26
Abstract: A focusing module for divergent light emitted from a source such as a laser diode.  The focusing module consists of telescoping cylindrical members which focus by sliding the members along their central axis and permanently adhering the members to each other after focusing.  The focusing lens is embodied in a lens assembly which prevents direct contact between the lens surface and the lens seat in one of the cylindrical members.  Axial rotation between the cylindrical members, and between the base and the module is prevented by a series of notch and key elements.  Consequently, the opening of the focusing module is fixed with respect to the cross-section of the light emitted, and can be shaped to match the cross section of the laser light beam thereby permitting maximum emission of focused light.

Abstract: ABSTRACT "Improvements relating to Heating Devices" A heating pad comprises an inner pouch 1 and an outer cover 2. The pouch 1 is formed from two sheets heat sealed together at their edges to enclose a heat retaining liquid with granules of ground up polyurethane foam material. The granules tend to act as heat stores so that when the liquid is heated the heating pad will give off warmth over a substantial period of time. The pouch 1 can readily be warmed by heating within a micro-wave oven, whereupon the relatively cool edge 7 of the pouch can be gripped to insert the pouch into the con-tainer 2 which is formed from a textile material with quilting lines 8. A connecting strip 9 will co-operate with a portion of a flap 10 so that the outer cover can be closed to protect the pouch 1. (Figure 1) -13-

Filed: 1990-05-14
Abstract: Abstract of the Disclosure:         In a decoding device for decoding an input signal into a decoded signal, a delay circuit delays the decoded signal into a delayed signal with a delay equal to a frame period of a digital video signal which is encoded into an encoded signal by interframe predictive encoding.  A forward filter of a predetermined filtering characteristic filters the delayed signal into a first filtered signal.  An adder adds the input signal to the first filtered signal to produce an added signal.  A subtracter subtracts the input signal from the delayed signal to produce a subtracted signal.  An inverse filter filters the subtracted signal into a second filtered signal.  Responsive to a mode signal, a selector selects one of the added and the second filtered signals to produce, as the decoded signal, the added and the second filtered signals when the mode signal indicates that the input signal is produced in a forward direction from a leading part to a trailing part of the encoded signal and when the mode signal indicates that the input signal is produced in a backward direction reversed relative to the forward direction, respectively.  Another inverse filter may be inserted between the delaying circuit and the subtracter.  In this case, the subtracter and the second filter are replaced in position with each other.

Title: High resolution microscoping system using convolution integration process
Inventor: TAKABAYASHI HITOSHI
IPC: G01N21/17
Filed: 1990-07-11
Abstract: Abstract of the Disclosure An optical system including a wave source radiates a converging wave to an object.  A first memory stores a function g(x,y) representing the intensity distribution of the converging wave at a substantially beam waist section thereof.  A scanning system directs the con-verging wave on the object at a substantially beam waist position, and operates so as to scan the converging wave on the object.  A detector detects the intensity of a secondary wave generated by interaction between the con-verging wave and the object in accordance with a scan-ning operation of the scanning means.  A second memory stores a positional function I(x,y) representing the intensity distribution of the secondary wave detected by the detector.  In order to obtain a sensitivity distri-bution representing the intensity of the interaction between the object and the converging wave, an arithme-tic unit obtains a function f(x,y) such that the func-tion I(x,y) stored in the second memory satisfies convolution integration of the function g(x,y) stored in the first memory and the function f(x,y).

Abstract: Abstract The invention concerns a reversible method for the thermal separation of liquid mixtures in a forced-circulating pressure-equalizing inertgas atmosphere.  For linearizing the different processes of heat and substance exchange, the inert gas flows, in adapted masses (quantities), through a degasser (1), an absorber (4), and a condenser (3).  With the mixture inflow and a recycled partial flow of the depleted solution (solvent) parallel-enriching, a heat transformation effect is achieved in the absorber (4).  This allows a complete recuperative recovery of the waste heat from condensation.         This method of mixture separation, combined with the method practised by Maiuri in the refrigeration section of a sorption refrigeration machine,  results in a reversible heat transformation method.  Its working temperature range is adjustable over the selected liquid mixture.         If this heat transformation method is combined with established partial methods for direct energy conversion, then the reversible transformation of heat into mechanical and electrical energy is accomplished through    recycling the total waste heat (fig. 2).

Abstract: The present invention provides a cement setting accelerator comprising 100 parts by weight of a sintered body, 5 to 70 parts by weight of an alkali metal carbonate powder and at most 170 parts by weight of a lime powder and a method of manufacturing the same. The sintered body contains a predetermined ratio of 3CaO?2Na2O?5A?2O3, Na2SO4 and Na2O?A?2O3.  Alternatively, a predetermine ratio of 3CaO?2Na2O?5A?2O3, Na2SO4 and 4CaO?3A?2O3?SO3 are contained in the sintered body. Further, a raw material mixture, which is not sintered and equal in the chemical composition to the sintered body noted above, may be used in place of the sintered body.  Setting and hardening of a cement paste is markedly promoted by adding a small amount of the cement setting accelerator of the present invention to the cement paste.  Also, the initial setting time of the cement paste can be controlled by controlling the amount of addition of the cement setting accelerator of the present invention.
