Abstract: Bei einem Verfahren und einer Vorrichtung zum Vorkühlen des Heliumtanks (19) eines Kryostaten (2), insbesondere für die Aufnahme einer supraleitenden Magnetspule (28) wird eine Verunreinigung des Heliumtanks (19) dadurch vermieden, daß in einem geschlossenen Kreislauf Heliumgas auf die Temperatur von siedendem Stickstoff gebracht wird, dieses Heliumgas durch den Heliumtank (19) geleitet wird und anschließend wieder auf die Temperatur von siedendem Stickstoff abgekühlt wird. Der Heliumtank (19) wird mit dem Heliumgas, das eine Temperatur von 77 K aufweist solange abgekühlt, bis er selbst diese Temperatur erreicht hat. Da das Innere des Heliumtanks (19) ausschließlich mit Helium in Berührung kommt, kann nach dem Erreichen der Vorkühltemperatur der Heliumtank (19) sofort mit flüssigem Helium gefüllt werden, ohne daß dieser zuvor gereinigt werden muß.

The load springs permit the forward flywheel to yield slightly from its operative position when the driver is introduced between the flywheels. An electric motor (7) and gear train drive the flywheels in counterrotation regardless of the position of the forward flywheel. A driver return system comprises a stationary idler roller and a return roller and gear train constantly driven by the rearward flywheel and pivotable thereabout between operative and inoperative positions. The driver is shiftable between a retracted position and an extended position A driver trigger (10) released locking means maintains the driver in its normal position. A driver actuator introduces the released driver between the flywheels. The tool has a safety (92) which controls the driver trigger, the driver actuator and the positions of the forward flywheel and the return roller.

Abstract: In a method for controlling the driving speed of draw plates in a multi-stage straight-lined wire drawing machine operating without slip, in which each drawing die is assigned one draw plate and each draw plate is driven by means of a speed-regulated or speed-controlled drive, the adaptation of the speeds of the individual drawing-die drives to the process-related parameters (wire diameter or reduction in wire cross-section) in the starting phase of the wire drawing machine is performed in a setpoint cascade via a feeler-roll position control which automatically matches the setpoint cascade, matching being proportional to the speed ratios of the draw-plate drives and independent of the absolute speeds or setpoints, and the feeler rolls (4) are transferred slowly into an end position for the continuous transition to direct straight-lined drawing by a control command to the feeler-roll position control, and the further control of the driving speed is assumed by the known back tension regulation or control method in straight-lined drawing mode and the feeler rolls (4) are guided out of the region of the wire. <IMAGE>

Abstract: There are provided a waveform generating section (12) for generating waveform sample data at a frequency corresponding a designated pitch, a coefficient generating section (14) for generating n coefficients that correspond to a desired interpolation characteristic, a characteristic-controlling section (15) for changing the coefficients to be generated in the coefficient generating section so as to variably control the interpolation characteristic, and an interpolation operation section (16) for operating the coefficients with n digital waveform sample data generated sequentially from the waveform generating section and synthesizing operated data to produce one sample data. With this arrangement, it becomes possible to control the interpolation characteristic and therefore a resultant filter characteristic in accordance with a desired mode, when generating a tone signal of a smooth waveform by waveform interpolation operation utilizing digital filter operation. For example, the interpolation characteristic can be controlled in accordance with a pitch or tone range so that a filter characteristic to be obtained as the result of the interpolation operation can be prevented from shifting as a pitch or tone range changes. Further, by controlling the interpolation characteristic in correspondence with a specific tone range, such characteristic can be established as to reliably eliminate an aliasing noise.

Abstract: A method of operating a communications system, particularly a FDM-TDD cordless telephony system, in which, in order to expedite handover, a portable secondary station builds up a record of the status and quality of the other FDM channels in the system by every 1 in n (where n is an integer greater than one) TDD frames monitoring another FDM channel. The value of n is adaptive in that, as the quality of its existing channel deteriorates, the value of n decreases, thereby updating its record more rapidly. At handover, the secondary station is able to choose immediately an acceptable alternative channel, thereby avoiding the time overhead of scanning all the other FDM channels.
