Title: Method and device for filtering of suspensions
Inventor: STRID KENT
IPC: B01D29/62
Filed: 1990-10-04
Abstract: In a method for filtering a suspension through a stationary filter (1a, 1b) having vertical filter element arranged in a pressure vessel (A, B) and far re-conditioning the filter after filtering, the filtrate is discharged from the bottom of the filter element (27) during the main part of the filtering.   After filtering unfiltered suspension is discharged in a known manner from the pressure vessel (A, B) later to be returned to the inlet (2a, 2b) for suspen-sion. Thereafter, back-wash is performed with an-other medium hate filtrate, an outlet (12a, 12b) for material deposited on the filter element being open-ed for removal of said material together with the back-washing medium. Preferably, before back-wash, drying of the material deposited on the filter element (27) takes place by means of a gas medium circulating within the filtering plant.
Patent CA-2052268-A1 (CA)
Title: Preserving the contents of beverage containers
Inventor: BERRESFORD RICHARD
IPC: B65B31/04
Filed: 1991-09-25
Abstract: Beverages, in particular wine, are preserved by forming an atmosphere within the container, above the liquid level, which will help to preserve the qualities of the beverage.      In the case of still beverages, a subatmospheric pressure will be produced by placing a non-return valve in the mouth of the container and then evacuating air from the container.      In the case of sparkling beverages, a superatmospheric pressure is produced instead. The pressure inside the container is produced by a motor driven pump and is controlled so that when a predetermined pressure level is reached, the pump stops pumping and the container is sealed.

Patent CA-2054631-A1 (CA)
Inventor: BIGUS JOSEPH P
IPC: H04M1/27
Filed: 1991-10-31
Abstract: A predictive dialing system having a computer connected to a telephone switch stores a group of call records in its internal  storage.   Each call  record contains a group of input parameters, including the date, the time, and one or more workload factors.  Workload factors can indicate the number of pending calls, the number of available operators, the average idle time, the connection delay, the completion rate,  and the nuisance call rate,  among other things.   Ih the preferred embodiment, each call record also contains a dial action, which indicates whether a call was initiated or not.  These call records are analyzed by a neural network to determine a relationship between the input parameters and the dial action stored in each call record.  This analysis is done as part of the training process for the neural network.   After  this  relationship  is  determined,  the computer system sends a current group of input parameters to the  neural  network,  and,  based  on  the  analysis  of  the previous call records, the neural network determines whether a call should be initiated or not. The neural network bases its decision on the complex relationship it has learned from its training data -- perhaps several thousand call records spanning several days, months,  or even years.  The neural network is able to automatically adjust -- in a look ahead, proactive manner -- for slow and fast periods of the day, week, month, and year.

At least one beam is tunable to the resonance frequency of the target gas and at least one beam is tunable to an off-resonance frequency of the target gas.  Means are provided for directing the beams through the atmosphere to be analysed to a land or sea reflecting surface in such manner that the beams are transmitted coaxially.  The beams are of such wavelengths that the on-resonance beam is attenuated by the presence of the target gas, if present in the atmosphere, and the off-resonance beam is not attenuated by the target gas.  Means are provided for collecting the reflected laser radiation of wavelength absorbed by the target gas and reflected laser radiation of wavelength unabsorbed by the target gas and for generating a differential signal; determined by the difference in returning energies between the reflected laser radiation of wavelength absorbed by the target gas and the reflected laser radiation of wavelength unabsorbed by the target gas.

Inventor: BAHL LALIT R
IPC: G10L19/00
Filed: 1992-02-04
Abstract: The  present  invention  is   related  to   speech recognition and particularly to  a new type of vector quantizer  and  a new vector quantization technique  in which the  error  rate  of  associating a  sound with an incoming  speech  signal  is  drastically  reduced.   To achieve this end, the present invention technique groups the feature vectors in a space into different prototypes at least two of which represent a class of sound.  Each of the prototypes may in turn have a number of subclasses or  partitions.   Each  of  the  prototypes  and  their subclasses may be assigned respective identifying values. To identify an incoming speech feature vector, at least one of the feature values of the incoming feature vector is compared with the different values of the respective prototypes,  or the subclasses of the prototypes.   The class of sound whose group of prototypes, or at least one of  the prototypes,  whose  combined value most closely matches the value of the feature value of the feature vector is deemed to be the class corresponding to the feature vector.  The feature vector is then labeled with the identifier associated with that class.

Title: Compact fiber-optic unit sensing 3 orthogonal directions simultaneously
Inventor: TERAOKA TATSUO
IPC: G01C19/72
Filed: 1992-06-24
Abstract: Each fiber-optic gyroscope unit is shaped like a tet-ragonal cone.    A square  plate (51) is used as a base which holds a light source module (52), a light receiving unit (detec-tor) (53) and an optical fiber coil (54).   Directional couplers (56) are also mounted on the base (51).   A phase modulator (55) which includes a piezoelectric element is disposed inside the optical fiber coil (54).   A signal processing circuit board (58) which has pedestals (59) stands on the base (51)  such that it positions above the optical fiber coil (54).   A polarizer (510) is wound around the optical fiber coil (54).    A reinforcement member (511)  is also provided.   All these components are so arranged as not to extend out of the tetragonal cone  (OABCO*) which defines its own unit  region.    Three  identical  fiber-optic  gyroscope units are combined by connecting members (512, 513, 514) to form a single fiber-optic gyroscope to detect rota-tional angular velocities about three orthogonal axes.    Since identical units (50) are used, the assembly is easy, and since the three units (50) are combined with respect to the axis of symmetry, the combined units (50) form a compact gyroscope.

Abstract: During assembly of one or more stacks of piezoelectric drive elements along the major axis of the elliptical shell (30) of a flextensional transducer the conventional technique is to apply pressure along the minor axis of the shell (30), insert the stacks together with pre-tensioning wedges, and then release the minor axis pressure. The invention provides a method for assembly of flextensional transducers by applying pressure uniformly over the entire outer surface of the elliptical shell (30) so as to extend the major axis of the shell (30); inserting and locating the stack(s) within the shell; and removing the pressure. The shell (30) is inserted within the enclosure (34) such that access to its interior is available for insertion of the piezoelectric stacks and sliding movement of the shell (30) relative to the enclosure (34) is possible.
