Patent DE-4136643-A1 (DE)
Inventor: SCHROEDER KARLHEINZ
IPC: F16H7/14
Filed: 1991-11-07
Abstract: In a drive unit consisting of an input shaft on the motor side and a belt drive with an output shaft, the shafts and belt pulleys are to be arranged in such a way that the bearing forces which arise at the units and driving motors are minimised, even at high driving speeds, and that the time taken for repair in retrofitting and replacement work is considerably reduced. This is accomplished by the fact that the belt drive consists of two belt pulleys (2, 3) which are mounted between two bearing plates (6, 7) and are releasably connected to the input and output shaft (15, 16) respectively, the bearing plates being split between the belt pulleys and being arranged displaceably on a cross-piece (8) on at least one side in order to allow the setting of the belt gripping pressure. <IMAGE>

Patent DE-4228479-A1 (DE)
Inventor: WALKER MICHAEL
IPC: H04R3/02
Filed: 1992-08-27
Abstract: In a circuit arrangement with means for echo cancellation by controlling the sidetone suppression for electroacoustic installations, particularly for a communication terminal (1) exhibiting a hands-free talking device (9), with transmitting and receiving branch (2 and 5) and gain-controllable amplifiers (VS, 4 and VE, 6), the sidetone suppression is set in such a manner that echo signals occurring during the speech phase are lowered to levels which do not interfere (simultaneous masking). According to the invention, means (10) are additionally provided or can be connected by means of which it is possible individually or automatically to cancel or to lower to non-interfering levels even echo signals which occur after the speech phase and the subsequent decrease in the hearing threshold of the human ear in time. As a result, a correct hands-free talking is also possible with the usual terminals (1) with little expenditure and therefore inexpensively when the connection is over long transmission paths, for example via satellites or via transmission links having a long propagation time. <IMAGE>

IPC: D06B23/24
Filed: 1992-10-03
Abstract: To determine the deg. of desizing a fabric (15), especially wovens, during the washing process the amount of material (15) treated, the washing fluid (19) flow and the concentration of sizing in the fluid (19) are measured. The deg. of desizing is set by the difference between the amount of sizing applied to the fabric and the vol. of sizing carried off by the washing fluid. Pref. the concentration is measured by a continuous refractometer. The amount of sizing contained in the washing water is also taken into account in the computation. The washing process is effected in a number of successive baths (12-14), with the concentration measurement at the last bath (14) in the flow direction, and pref. also in the penultimate bath (13). The desizing process is controlled according to the measured data, pref. by adjusting the material (15) feed speed. The desizing is a continuous process. USE/ADVANTAGE - The method is for removing the sizing from fabrics, and especially wovens, where the warps have been previously sized for protection during weaving. The system gives an effective and controlled desizing action, during washing, to give a set character.
