IPC: G10L17/06
Filed: 1990-04-18
Abstract: Speech recognition is carried out by recording multiple examples of a vocabulary of known words. The examples of each word are temporally aligned and supplied to a neural net 20 which identifies the features of each word which discriminate it from other words in the vocabulary. These discriminative features are integrated with parameters of a Hidden Semi-Markov model and stored at 17. Speech signals from unknown words are then compared with the stored information after syntax restriction. <IMAGE>

Title: Removing radioactive caesium from solns. and suspensions etc. - by filtering, recycling retentate to batch containers, feeding permeate to ion exchange, and adding permeate to previous retentate
Inventor: GIESE WERNER PROF DR
IPC: G21F9/12
Filed: 1990-06-29
Abstract: In removing radioactive Cs from suspension, solns. and similar liqs., (a) the liq. is brought to a uniform compsn., opt. after processing from a dry pre-prod., (b) the liq. is conditioned w.r.t. temp. and filtered, and the retentate, harmful to an ion-exchanger, is recycled into a batch container, (c) the Cs-contg. permeate is fed to an ion-exchange, where the Cs bonds to the ion-exchange material, and the permeate freed from Cs is recycled to the retentate in the batch container, and (d) this circulation is maintained until the contamination of the liq. in the mixing container has fallen below a pre-determined level. The novelty is (e) the ion-exchanger material is a support coated with NH4-Cu hexacyanoferrate complex, (f) the support, not taking part in the exchange of Cs ions, is highly porous spheres of synthetic material, with large surface and with high binding capacity to the ion-exchange material, and (g) the spheres have dia. 0.4-1.2 mm.

The claimed use is the decontamination of whey powder, by dissolving the powder in water in ratio 1:4. subjecting to ultrafiltration, when the protein is retained in the retentate and a lactose-salt soln. is fed as permeate to the ion-exchange, and the soln. formed after removal of Cs from permeate and retentate is spray dried. The prod. is not affected by the ion-exchange material. Filtration, ion-exchange and withdrawal of the decontaminated prod. can be continuous. High loading of the ion-exchanger is obtd., with very low activity in the treated prod..

Title: Microcrystalline amorphous metal strip mfr. - using homogenised molten metal cooled in stages with homogeneous magnetic field
Inventor: MARKOV TZVETAN MIHAYLOV DR
IPC: B22D11/12
Filed: 1991-04-12
Abstract: To produce microcrystalline and amorphous metal strips, from molten metal, the molten metal is homogenised before it is fed to the cooling rollers. The molten metal is cooled in stages, by zones, under control, while an electrical field is developed between the rollers at the same time to form a homogenous magnetic field. To give thin and amorphous stirps 0.01-0.07 mm thick the molten material is fed to a shaping roller by pouring freely over the surface. It is then rolled between the shaping roller and a further roller. F0r metal strips 0.07-0.35 mm thick, with an oriented microcrystalline structure, the homogenised molten metal is poured vertically or at an angle to the contact line between two rollers to give a simultaneous shaping and rolling action at a temp. above the Curie point. The magnetic orientation of the metal strips uses a homogeneous magnetic field with a simultaneous controlled cooling at a temp. through and below the Curie point. An induction homogeniser (4) and a microcrystalliser (4) with an integrated jet (3) is between the crucible (1) and the rollers (5). A system to ionise the molten metal (6) is at the rollers. The section (8) to give a magnetic orientation and a controlled cooling chamber (7) are below the rollers. ADVANTAGE - The method extends the zone of the geometric mass of the metal strips to give a stability to the microcrystalline and amorphous structures. This gives improved physical and mechanical characteristics.

Abstract: A flow control device has a valve housing, in which are seated one or more conical rotary bodies, each with a curved passageway which extends from an end face opening through less than 90deg.  to a peripheral opening in the conical section of the body.  The housing has a corresponding conical bore section having, for each rotary body, at least two connection openings to channels in the housing so that, on turning of the rotary body, the channels are alternately connected to the end face opening. The device pref. has at least two such rotary bodies (1) united axially parallel in a common housing (2) with several connections (14) to form a multi-way valve, each rotary body (1) being independently driven esp. by a shaft (3) which is located at the opposite end from the end face opening (12) but which is coaxial to the rotary body. USE/ADVANTAGE - The flow control device is useful in a mixer battery for two or more fluids (esp. for mixing paints and chemicals), in a water mixer tap, as a four-way mixing valve in a heating system, in the power systems of large equipment, for controlling the inlets of water and steam turbines, for liq. control in nuclear power stations, as an overpressure valve, as a switchpoint in a pneumatic post system, or in a wind instrument.  The rotary bodies can be mass produced so that costs are reduced by about 50%, only the housing needing to be tailored to the particular use (e.g. in a wind instrument).

Title: Reactor lattice structure, esp. for BWR reactors - for support, insertion and removal of fuel and control rod assemblies
Inventor: RAU PETER DIPL ING
IPC: G21C5/02
Filed: 1991-05-29
Abstract: A spacer structure for nuclear reactors, especially hot reactors, which are similar to boiling water reactors, but of smaller power capacity.
