Title: Method and device for the temperature compensation of an attenuator
IPC: H03H7/54
Filed: 1988-12-16
Granted: 1989-11-23
Abstract: For an attenuator, the attenuation of which increases with increasing temperature when driven with a constant voltage and decreases with increasing temperature when driven with a constant current, a method which can be implemented with the simplest possible circuit means and a corresponding driving device for temperature compensation are to be specified. For this purpose, the attenuator is simultaneously current- and voltage-controlled and the ratio between current and voltage control is selected in such a manner that the variation of the attenuation with temperature caused by the current control is compensated by the variation of the attenuation with temperature caused by the voltage control.
Patent DE-4105408-C1 (DE)
IPC: H05H1/42
Filed: 1991-02-21
Granted: 1992-09-17
Abstract: The plasma spray gun has an indirect plasmatron for generating a long arc. Said plasmatron has at least one, for example, three, cathodes (1,20), an annular anode (3) which is at a distance from the cathode, and a plasma channel (4) which extends from the cathode to the anode. The latter is formed by the anode ring (3) and a number of annular neutrodes (5 to 12) which are electrically insulated from one another. The plasma channel (4) has a constriction zone (33) in the region close to the cathode and expands from this constriction zone towards the anode (3). The spray material (SM) is supplied with the aid of a carrier gas (TG) through a central tube (24) which opens in the centre of an inlet nozzle which is formed by the neutrode (5) located closest to the cathode. 
<??>Using this solution, a higher efficiency and an increased life of the plasma spray gun can be achieved.

Title: Machine tool positioning system - determines position of groove on workpiece, giving voltage corresp. to circumference, and angular position of tool spindle, and uses phase difference between two sets of signals to position motors
IPC: G05B19/18
Filed: 1991-10-10
Granted: 1993-05-06
Abstract: The system positions a tooth-cutting or groove-making tool (21) automatically relative to a workpiece (10) with a previously made indentation or groove (12). The tool is mounted on a spindle (14) running across, or oblique to, the workpiece spindle (3). The tool spindle can be adjusted in the direction of its axis (15) or across it by positioning motors. The angular position of the indentation or groove is determined by an analogue sensor (28), giving a voltage corresp. to the circumference of the piece. The voltage is scanned and digitised into discrete voltage values as measuring signals, while the angular position of the tool spindle is determined by a second analogue sensor (35) in a similar way, giving reference signals. The phase difference between the two sets of signals is found, providing a control signal for the positioning motors. ADVANTAGE - Improvement in accuracy and speed.

Granted: 1994-09-15
Abstract: FIELD: control mechanisms of transport vehicle. SUBSTANCE: mechanism comprises shift shaft which, turning together with drive link, turns the body of ratchet mechanism counterclockwise. Driving pawl engages the opening in the disc thus turning the latter and the shift forks by means of curvilinear slots to a position corresponding to thrown-in gear. Simultaneously, a driven pawl slides over projection of ejector and becomes disengaged from corresponding disc opening. As the body is brought to initial position by a return spring (in a clockwise direction), the chamfer of the driving pawl is disengaged from the disc opening and is forced by a spring into the adjacent opening of the disc. The driven pawl slides in clockwise direction over projections of ejector and is forced by a spring into the corresponding opening of the disc. During a gear change the functions of the pawls are exchanged and further gearshifting proceeds in a similar manner. EFFECT: improved design. 5 dwg

Abstract: FIELD: precision instrument engineering. SUBSTANCE: layer of non-superconducting material 3 is applied onto superconducting surface of inertial body 2. Thickness of layer is equal to  , where H o  is nominal strength of magnetic field in working space of the suspension, H кр  is critical value of strength of magnetic field for superconducting material of inertial body, d o  is nominal working space between short-circuited superconducting coils and inertial body, K is strength restriction coefficient of maximal magnetic body. Inertial body moves under effect of acceleration; in this case one working space increases, and the other one decreases. Magnetic force increases in the reducing space, as strength of field increases (the force is proportional to magnetic field strength squared). Force reduces in the increasing space. Arise of the force is directed in opposite to effect of acceleration. Inertial body stops to move when balance between the forces is achieved - when inertial and magnetic forces are equal.
