Title: Method and device for manufacturing of oxigen sensor
Inventor: TODOROV NEDKO T
IPC: G01N27/416
Filed: 1989-03-22
Abstract: This method and device are used in electronics. It enhances the degree of repetition of the sensor's characteristics and the output in its production. The method consists of the formation and baking of enamelling coverage from a solid electrolyte, layers of glass mass and porous ceramics in a neutral gaseous medium, by radiation with heat and light radiation from a source (1.1, 1.2, 1.3) with an internal temperature higher than 3,000 degrees C. After this, a check-up of the prepared sensor is carried out. The device contains a chamber (4), in which the blank (2) is placed, sources of heat and light radiation (1.1, 1.2, 1.3), focused onto it, an observation device (3) and a refined positioning (5) of the blank (2), a manageable gas-supply node (6) and a computer bloc (7) for tracking and management of the technological regime (a baking temperature and a composition of the gaseous medium). The device is used both for the production of the sensor, and for its consequent check-up.

Title: Method and device for manufacture of amorphous and monocrystal metal strips
Inventor: KHRISTEMOV DIMITAR M
IPC: B22D27/02
Filed: 1989-05-05
Abstract: The method and the device can be applied in foundries. It offers the possibility to control the thickness of the longitudinal and transverse profile of the metal strip during the casting process. By this method the molten metal is fed under pressure through a nozzle upon a rotating cooling surface and before it reaches that surface the metal passes through a transversal magnetic field. The distribution of the intensity of the magnetic field along the width of the nozzle corresponds to the desired transversal profile and the intensity of the magnetic field changes in time by a law- to the desired longitudinal profile of the metal strip being manufactured. The device includes a hermetically sealed vessel for metal melting (1) with a nozzle (3) against which a rotating cooling body (4) is situated. In the zone of the nozzle (3) an electromagnetic system is installed which consists of a magnetic pipeline (5) from magnetic soft material and an excitation coil (6) which is connected to a source of regulated voltage (7) connected to a control circuit (8). In a version of the device the magnetic pipeline (5) is made of profiled pole terminals (9).

Title: Drive system for railway vehicle
Inventor: SANDBERG LENNART
IPC: B60T8/17
Filed: 1990-10-22
Abstract: ABSTRACT            A rail vehicle has a drive system with two or more d.c. drive motors (M1, M2, M3) and with means (SRA) for common control of the armature currents (UA) of the motors. Futher, the system has means (SRF1, SRF2, SRF3) for individual control of the fields of the motors.  The system further comprises two comparison means which generate differences between the armature currents of the motors. These differences control the fields in the respective motor so that the armature current in each motor can be controlled separately.  Further, the system includes a logic unit to the input of which there are supplied a measured signal, which indicates the armature current intensity of the motor for the axle which has the best adhesion, usually the trailing axle motor, as well as an amplification signal. These two signals are multiplied by each other and the product signal is used in a loadsharing system to control the other motors such that the torque of the trailing axle motor is reduced, the trailing axle then rolling very close to ground speed.  This speed is used as a measure of the true speed, which controls an overspeed feedback control system, which in turn controls the system for loadsharing such that the vehicle can be controlled to maximum tractive effort without torsional oscillations.

IPC: D21C3/22
Filed: 1990-11-16
Abstract: ABSTRACT OF DISCLOSURE           Disclosed is a procedure for the production of mechani-cal pulp from a fibrous product. To reduce a refining energy, the fibrous product is subjected to an enzyme treament in which an en-zyme acts on lignin in the fibrous product.  When oxidizing en-zymes are used, it is preferable to adjust the redox potential to the optimum level characteristic of each oxidation-reduction en-zyme by means of suitable oxidation-reduction chemicals.  In addi-tion to reducing the refining energy consumption, the enzyme treatment also improves the strength properties and the blue reflectance factor of the pulp.

Inventor: ROZE ULDIS
IPC: B27K3/52
Filed: 1991-01-17
Abstract: U. ROZE ABSTRACT Based upon the discovery that porcupine attack of wood structures is due to the presence of sodium in the conventional resin used in the wood structures, the invention provides for replacing the base used in wood processing with potassium hydroxide or ammonium hydroxide or any other non-sodium base.          Potassium hydroxide is found to be a specific deterrent to porcupines.  A preferred resin formulation contains potassium hydroxide as the base, and an additive of potassium chloride in an amount of from 5% to 20%, and preferably 10%, by weight of the potassium hydroxide.  The potassium-containing resin formulation may be used to make potassium-containing wood products, applied as an adhesive for gluing together wood objects accessible outdoors, mixed with a water-insoluble gum or paint or used to make potassium-containing panelling or shingles which are applied to existing wood structures to render them porcupine-proof.
