Title: Casting-pipe arrangement, particularly for launders in continuous casting installations
Inventor: ENGELMANN KURT
IPC: B22D41/58
Filed: 1986-10-14
Granted: 1988-03-31
Abstract: A casting-pipe arrangement, particularly for launders in continuous casting installations, is to be improved while providing effective screening of the casting-pipe connection against air ingress. This is essentially achieved by virtue of the fact that a recess (33 or 70) is provided in the nozzle brick (6 or 54) around the discharge end of the discharge sleeve (13 or 55) and, together with the connected casting pipe (15 or 58), this recess forms a protective-gas chamber (35 or 71) which surrounds the connection and is connected to a conduit system (37 or 73). This makes the casting-pipe arrangement simpler in design and fully proof against air. <IMAGE>

Title: Circuit arrangement for overvoltage testing
IPC: G01R31/3161
Filed: 1988-04-18
Granted: 1989-06-08
Abstract: To test the overvoltage of a load (6), a circuit arrangement should inexpensively generate overvoltage pulses, the peak value and variation in time of which are variable. For this purpose, a first AC converter (1) applies to the load (6) its rated voltage and a connectable second AC converter (2) connects the load to an adjustable voltage which is higher than the rated voltage. The higher voltage can be adjusted, particularly by phase-angle control and is phase-shifted compared with the rated voltage applied to the load (6). <IMAGE>

Title: Movement brake
Inventor: MATHIAS RAINER
IPC: E05F5/00
Filed: 1993-06-19
Granted: 1994-08-18
Abstract: A movement brake having small radial dimensions is specified, which has an elongate housing which is, for example, of hollow-cylindrical design and in which a friction part, for example a viscous compound, is contained and in which a roller-shaped rotary part is arranged with rotary movement and can be connected in terms of movement to a part which is to be braked. In this case, the axial outer circumferential surface of the roller-shaped rotary part is used as the effective surface for producing the braking force. Furthermore, a movement transmission connection to the part to be braked is provided on each side of the rotary part. Furthermore, the movement brake can be coupled or decoupled, for which purpose the housing may be provided on the outer surface with grooves in which an actuating part can engage. When the housing has been fixed and retained with the aid of the actuating part, a braking force can be produced by the movement brake whereas, when the housing is rotating, the movement brake is ineffective and is decoupled.

Title: Engine idling speed control module
Inventor: WATANABE SATORU
IPC: F02B75/02
Filed: 1993-08-19
Granted: 1994-09-22
Abstract: A device for adjusting the engine idling speed to a set value calculates a set engine idling speed appropriate to engine operating conditions and a model engine speed on the basis of the set engine idling speed calculated. The calculated set-model engine speed is used in order to calculate a model engine output torque, which is required so that the actual engine speed follows the calculated model engine speed. A difference between the engine speed detected and the calculated model engine speed is calculated in order to correct the model engine output torque. The corrected model engine output torque is used, together with the calculated model engine speed, in order to calculate the rate of air flow through the secondary air passage.

Title: Venting appts. for mixing and conveying device
Inventor: BRINKMANN FRITZ
IPC: B01F35/60
Filed: 1994-07-15
Granted: 1996-02-01
Abstract: The venting appts. has a compressor connected to a mixing vessel (10), which is switched off, after the transfer of mixed material from it is complete.
