Inventor: FRIEDLI PAUL
IPC: B66B1/14
Filed: 1995-08-17
Abstract: This equipment enables an implicit input of destination calls in lift plants. An information transmitter (1) after a corresponding enquiry sends data (6) to a recognition device (5). These data (6) can contain direct information about the desired destination storey or serve for identification of the lift user and thus enable an access to the information, which is filed in a storage device (8), about the destination storey. The storage device (8) is accommodated in a processing unit (9) of a lift control (10). The communication between the recognition device (5) and the information transmitter (1) takes place by means of radio frequencies. With the aid of the obtained data (6), the destination storey is evaluated in the processing unit (9) and fed to the lift control (10). The allocation is made known to the passenger on a display (18). The process of the call entry takes place automatically, contactlessly and independently of the orientation of the information transmitter (1), i.e. it need not be visible for the recognition device (5). An input equipment (19) is mounted for changing the storey proposed by the processing unit (9).

Title: Method and apparatus for cleaning flue gas
Inventor: CARLSSON KURT
IPC: C01B17/60
Filed: 1994-03-04
Abstract: A method and an apparatus for cleaning a flue gas stream containing hydrogen chloride and sulphur dioxide are disclosed. The flue gas is treated in a wet cleaner (5), thereafter injected with lime (9) and filtered through a filter (13). The method and the apparatus are by the fact that a part of the flue-gas stream is bypassed the wet cleaner (5) through a conduit (15), to join the remainder of the flue-gas stream before the filter (13). In this way, hydrogen chloride in the bypassed stream is reacted with injected lime to form calcium chloride, which promotes the sulphur-dioxide separation upon the injection of lime.

Title: Bridge circuit magnetic field sensor with spin valve magnetoresistive elements and method for its manufacture
Inventor: DOVEK MORIS MUSA
IPC: G01R33/09
Filed: 1995-09-14
Abstract: A   magnetic   field   sensor   uses   four   individual magnetoresistive spin valve elements electrically connected in a bridge circuit.   The spin valve elements are lithographically formed on the same substrate with their free layers having their magnetization axes parallel to one another.   An electrically conductive  fixing  layer  is  formed on the  substrate but is insulated from the spin valve elements.   The application of current through the fixing conductor during fabrication of the field sensor fixes the direction of magnetization of two of the pinned  layers  to  be  antiparallel   to  the  direction  of magnetization of the other two pinned layers.  The bridge circuit output voltage is responsive to an external magnetic field in the plane of the sensor.  By appropriate fixing of the direction of magnetization of the pinned layers during sensor fabrication, and appropriate connection to the input and output leads, the bridge circuit output voltage is a measure of either the magnetic field or field gradient.  The fixing conductor, or a separate current strap formed on the substrate, can be used to pass an unknown current over the sensor, in which case the bridge circuit output voltage is a measure of the unknown current.

Filed: 1994-03-01
Abstract: Methods and apparatus for releasing energy from hydrogen atoms (molecules) by stimulating their electrons to relax to quintized lower energy levels and smaller radii (smaller semimajor and semiminor axes) than the "ground state" by providing energy sinks or means to remove energy resonant with the hydrogen energy released to stimulate these transitions. An energy sink, energy hole, is provided by the transfer of at least one electron between participating species including atoms, ions, molecules, and ionic and molecular compounds. The energy hole can comprise the transfer of electrons from one or more donating species to one or more accepting species whereby the sum of the ionization energies and/or electron affinities of the electron donatting species minus the sum of the ionization energies and/or electron affinities of the electron accepting species equals approximately m x 27.21 eV (m x 48.6) for atomic (molecular) hydrogen below "ground state" transitions where m and I are integers. The invention comprises methods and structure to conform the energies of the source, hydrogen, and the sink, energy hole, to enhance the transition rate. The energy reactor includes one of an electrolytic cell (100), a pressurize hydrogen gas cell (200) and a hydrogen gas discharge cell (300).
Patent CA-2165558-A1 (CA)
Title: Multiphase electric machine with a winding made of flat-shaped structural conductor parts
Inventor: HILL WOLFGANG
IPC: H02K3/12
Filed: 1994-06-23
Abstract: Known bar windings and pulled coils are made of bent bar conductors with a constant cross section and thus insufficiently use the space available in the winding overhang.      In addition, because of the bending radii to be respected, in particular in high-pole machines, long connection sections are obtained in relation to the pitch value, so that weight losses are increased. The disclosed shaped conductors are produced without bending radii in a single piece according to their final shape. Their cross section varies in the winding overhangs, so that the space available is utilized to a high extent and short connection sections are produced. Successive shaped conductors are arranged in different layers, so that interlaced multiphase double layers are produced. The length of a conductor lane formed by shaped conductors connected in series is independent from the depth of the grooves and all phase conductors of an interlaced double layer have the same design. Enlarged connection sites accessible at all times to all front faces of the winding overhangs are obtained by shaped conductors with asymmetric ends assembled in pairs before mounting. Motors and generators equipped with said shaped conductors are characterized by high efficiency and power densities.
