Abstract: ABSTRACT OF THE DISCLOSURE:           A crystalline, porous, synthetic material useful as a molecular sieve, as an ion exchanger or as a catalyst, is a material of zeolitic character.  It contains silicon, titanium and iron oxides and corresponds, in its calcined and anhydrous state,  to the following empirical formula p HFeO2 . q TiO2 . SiO2.  In this formula, p has a value greater than zero and lower than or equal to 0.050, q has a value greater than zero and lower than or equal to 0.025,  and the H  of HFeO2 can be at least partly replaceable or replaced by cations.

Title: Method for decreasing energy consumption during refining of fiber material while maintaining capacity
Inventor: GULLICHSEN JOHAN
IPC: D21D1/12
Filed: 1987-06-15
Granted: 1992-08-18
Abstract: ABSTRACT      The energy consumption of a cellulosic fibrous material refiner is significantly reduced, while the capacity is maintained by reducing grinding frequency while increasing the retention time and power amplitude (edge bar load).  The grinding frequency is maintained between about 200-2,000 Hz, preferably between about 300-900 Hz.  The retention time is more than a second, being increased at least about 100 times compared to conventional disk refiners. The power amplitude is at least doubled.   Retention time is increased by greatly increasing the retention volume by removing the majority (at least about 90%) of the steam at approximately the area that it is generated, minimizing the number of cutting elements, and disposing the grinding surfaces of the refiner so that they define a volume of revolution (e.g. a frusto-conical or cylindrical volume).

Patent CA-1299920-C (CA)
Title: Multi-sectional rail vehicle for short distance traffic
Inventor: KLEIM KARL-HEINZ
IPC: B61C3/00
Filed: 1987-10-02
Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE         The invention concerns a multi-sectional rail vehicle for short-distance traffic.  In a vehicle of this type it is desirable to have the entry-ways only slightly above the street level, and to be able to walk through the whole vehicle without climbing steps.  For this purpose there is provided, in accordance with the invention, a continuous centre aisle on one level, which is put at the same level as the entry-ways.  In order to accommodate the power bogies, the driving of the wheel sets is done via universal-joint drive shafts and step-down gearing systems.  In this manner the driving motors can be affixed laterally underneath the rail carriages, beyond the swivelling range of the power bogie.  Where space permits, vertical motors can also be installed in one of the corners of the rail carriage, which similarly drive the wheel sets via universal-joint drive shafts and step-down gearing systems.  Also advantageous is a design where two driving motors are located diagonally to the fulcrum point of the power bogie, their drive shafts being affixed parallel to the wheel sets, whereby the torque power is transmitted via universal-joint drive shafts.          The cross-bars of the power bogies are cranked so that they can carry the centre aisle.  By having the entry-ways and the continuous centre aisle on the same level, the movement of passengers is speeded up, stopping times are reduced, and costly railway platforms at floor level become superfluous.

Abstract: ABSTRACT OF THE DISCLOSURE            Speaker verification is performed by converting a spectral analysis of an input speech signal into a digital format. This digital format is sent directly to the address input of memory  storage defining the address which contains relevant  information  pertaining  to  the  actual  speech spectrum.   After training, each address contains labels defining whether the address  is not used,  is used by multiple users,  or is used by a single user.   Actual verification is performed by counting each occurrence of a valid user address during speech input by a speaker and selecting the highest count as indicative of the user who was speaking.
