Patent CA-2262732-C (CA)
Inventor: FENNOCCHI ARNOLD
IPC: H02K1/20
Filed: 1997-08-05
Granted: 2006-05-23
Abstract: A rotary electrical machine comprising a plurality of disc-shaped stator stages and a plurality of disc-shaped rotor stages, each of the rotor stages being respectively alternately interleaved with the stator stages. A space is provided between each stator stage and its adjacent rotor stage. Each of the stator stages is provided with at least two stator windings, defining a passage therebetween adjacent windings. A coiled pipe is disposed in or formed integrally with each of the passages in substantially the same plane as the stator stage, such that the outlet of one pipe is coupled with the inlet of the pipe disposed in the adjacent passage.      In use, fluid, for example, air, helium, water or oil is caused to flow around the coiled pipes in the passages between the stator windings. At the same time, cooling gas, for example, air or helium, is caused to pass through the stator-rotor spaces so as to cool the magnets, etc. and the retention hoops, etc. of the rotor stage as well as the outer surfaces of the stator stage. Alternatively, the stator-rotor spaces may be held under a vacuum.

Title: Automatic neighbor identification in a cellular system
Inventor: KAHN COLIN LEON
IPC: H04B7/26
Filed: 1999-02-26
Granted: 2002-07-02
Abstract: In a cellular system, a new cell measures signal strengths of different channels being used by existing cells. The new cell generates a list of candidate channels corresponding to the channels with the greatest signal strength and transmits the list to the mobile switching center (MSC) of the cellular system. The MSC determines which of the candidate channels correspond to beacons in existing cells and transmits configuration information to the new cell for those corresponding existing cells. In this way, the new cell automatically receives configuration information on its neighbor cells. If the MSC determines that the number of candidate channels that are beacons is too small, the MSC will ask the new cell to transmit additional candidate channels (i.e., those having even lower signal strength).

Patent CA-2289331-C (CA)
Inventor: WALTER ROLF
IPC: B27B17/00
Filed: 1999-11-10
Granted: 2007-04-17
Abstract: The invention has the object to improve a handheld portable work tool with an internal combustion engine such that the carburetor heater and the grip heater can be supplied with respectively adjusted electrical energy. By separating the generator windings into individual, electrically separated groups of excitation coils, an adaptation to the respective heating device with an optimal operating point is possible. The electrical separation into individual excitation coils and their selective combination into sets of excitation coils, which in the circumferential direction of the pole wheel are arranged in a row adjacent to one another, has furthermore the effect that a voltage drop caused by field weakness as a result of a load current has only a minimal effect on the other set of excitation coils. The coupling by a common coil resistor of the generator coil is thus eliminated.

Granted: 2008-12-02
Abstract: The invention relates to a method for producing an aqueous solution of free hydroxy-lamine by treating a hydroxylammonium salt with ammonia in the counter-current in a stripping column. As a result, hydroxylamine is released and at the same time, the solution obtained is separated into an aqueous hydroxylamine solution and a salt fraction by distillation. The inventive method is simple and mild, and can be carried out on a large scale. The risk of decomposition is minimal due to the low thermal burden, the low concentration of hydroxylamine and the short residence time involved in the process.
