Patent DE-2919026-A1 (DE)
Title: Guide for weft inserted by propelling jets - formed as open channel by differing upper and lower dents
Inventor: SCHEFFEL WALTER
IPC: D03D47/30
Filed: 1979-05-11
Abstract: Thread-guiding channel for the insertion of the weft propelled by a flowing medium in a loom, is formed by a series of dents, and is open towards the reed. The inserted weft thread is thus able to come into contact with the reed, whilst its flight path through the shed is limited below by different dents from those above. These dents which form the lower enveloping plane of the guiding channel pass through the web of warp threads at other places than those through which the top dents forming the upper enveloping plane pass. Arrangement makes possible a redn. in the height of the structure necessary, so that the opening of the shed can be reduced, and higher speeds attained. The possibility of the crossing over of warp threads on the bottom leg of the dents, and weaving faults arising from this are eliminated. The new dents separate the warp threads only once for each cycle of the loom. The repeated arrangement of bottom dents which constantly widen and narrow the channel, reduces swirling currents and avoids soiling of the fabric by fibrous material.

Patent DE-2941304-A1 (DE)
Inventor: KOCHI AKIHIKO
IPC: H01G7/04
Filed: 1979-10-11
Abstract: In order to reduce the temperature hysteresis effect ( epsilon H- epsilon L), an addition of an element of the group Nb, Ta, Sb, Bi, Th, W and Sc is introduced into barium titanate, and by providing also for the replacement of some of the ion constituents by an element of the group Sr, Ca, Zr, Hf or Sn, it is possible to obtain, after sintering and heat treatment, particles of a very small diameter. Measurements make it possible to keep this diameter below a value of 5 mu  for which (Figure 7) the significance of the hysteresis effect ( epsilon H- epsilon L) becomes extremely low. The dielectric material and the capacitor formed by means of the latter find a particularly advantageous application as compensation element, according to the temperature characteristic, in a great number of portable electronic devices. <IMAGE>

Patent DE-2950005-A1 (DE)
Inventor: HASSLER DIETER DIPL ING
IPC: G01S7/52
Filed: 1979-12-12
Abstract: In an exemplary embodiment, an ultrasonic array has an installation for dynamic focusing at least in the transmitting mode. It is the object of the disclosure to avoid excessively great time loss, and yet to permit dynamic focusing also in the transmitting mode. This object is achieved in that, in the case of a specifiable number of depth regions (with a respective fixed focusing in each depth region) preferably associated with each scanning line of the ultrasonic scanning, the transmitting/receiving cycle for each fixed focusing is progressively introduced in such a manner that, for every depth region of each such scanning line, transmission is effected at such a time-point which immediately follows, for example, that time interval in which echo information was received from the chronologically prior-scanned depth region for such scanning line. More generally, the second ultrasonic pulse for a given scanning line occurs while echo signals due to the first pulse are still returning from the depth extent of the body which is under examination.

Patent DE-3000983-A1 (DE)
Inventor: BISCHOFBERGER WALTER
IPC: H01H33/34
Filed: 1980-01-12
Abstract: In the case of hydraulic drives for electrical circuit breakers (8) having a differential piston (2c) which can move in a cylinder (2) and can have hydraulic fluid applied to it differently by means of a reversing valve (5) and a control-valve device (1, 7, 10, 11, 13, 15), the control-valve device in each case has at least one switching-on valve (1) which can be triggered by a switching-on command element and controls a hydraulic switching-on command, and one switching-off valve (10, 11), which can be triggered by a switching-off command element and controls a hydraulic switching-off command. In the case of such drives, in order now to make it impossible for the circuit breaker (8) to be switched on and off by simultaneous triggering of the valves (1, 10 or 11), the high-pressure side (10b, 11b) of the switching-off valves (10, 11) is connected via a valve (15) to its low-pressure side (10a, 11a) for at least as long as the switching-off command is in existence, until the switching-on valve is closed. In consequence, pumping (repeated switching on and off) of the circuit breaker is reliably rendered impossible. <IMAGE>
