Title: Rate of change of current limitation circuit for transistor - has load current premagnetised saturable choke which is unsaturated when freewheeling diode current is zero
Inventor: RONA WOLFGANG DIPL ING
IPC: H02H9/00
Filed: 1978-07-07
Abstract: The rate of change of current in an h.v. transistor operating at a high frequency can be limited by including a saturable choke (Lb) which is magnetically biased by the load current. This bias is arranged so that the choke is unsaturated when the current through the freewheel diode (F) across the load reaches zero. The choke (Lb) may be additional to the normal limiting choke (La). The operation of the load current biased choke is to reduce the transient voltages on the diode. As the additional choke acts to protect the diode the latter need no longer have an RC snubber circuit in parallel and thus the efficiency of the circuit is improved.

Title: Plate ionisation chamber has alternating signal and voltage electrodes - of open lattice structure slightly domed for stiffness
Inventor: MENGELKAMP BERNHARD ING GRAD
IPC: H01J47/02
Filed: 1980-06-07
Abstract: A plate ionisation chamber for beta and soft gamma radiation comprises a number of rotationally symmetrical potential and signal electrodes arranged one behind another. The potential electrodes and the signal electrodes are made of thin foil, with large portions cut away to leave a lattice or grating structure; these electrodes are stabilised by deforming them, more specifically by a flat dome shape. The electrodes may be produced by a mould etching process. A signal electrode is composed of rings and radial webs; the voltage electrode has a similar pattern but the webs of voltage and signal electrodes are staggered relative to each other to improve the homogeneity of the field strength. In addition, the active chamber volume may be separated from dead space by peripheral collars or flanges integrally formed on the signal electrodes around their perimeter. The homogeneity is improved by having electrodes with comparatively large open areas but without the difficulty of applying a large number of bores to a plate. Manufacture is inexpensive and simple.

Title: Tunnel kiln, esp. for baking ceramic prods. - where positive air pressure in lower part of kiln precludes ingress of cold external air
Inventor: ROEHRL JOSEF
IPC: F27B9/26
Filed: 1980-06-11
Abstract: The inlet and exit ends of the kiln are provided with at least one door; and a row of kiln cars travel along rails on the base of the kiln. The row of kiln cars divides the kiln into a longitudinal upper zone (I), and a longitudinal lower zone (II). A heat transfer medium streams along both zones (I,II). Transverse baffles are pref. located in zone (II) to reduce the flow of the heat transfer medium along this zone (II); and the baffles are pref. located on the underside of the kiln cars. The heat transfer medium is e.g. air flowing through an inlet duct at the exit end of the kiln. The flow of air along zone (II) prevents the entry of external and unwanted cold air into the kiln. Such cold or "false" air impairs temp. control in the kiln.
