Title: Mass production system for thyristors - holds contact wires on metal strip, bends wires and chip is inserted and soldered
Inventor: AKYUEREK ALTAN ING GRAD
IPC: H01L21/56
Filed: 1977-06-11
Abstract: The thyristors are esp. miniature thyristors. They are produced by contacting electrodes on the SC chip on a metal strip placed transversally to it and divided in groups of three for each thyristor. They are provided for contacting with metallisation (electrodes) and with at lest one metal platform. The chip is soldered and insulated, and unnecessary connecting parts are cut off. Contact wires (2-4) held on one single metal strip serve as the electrodes. One (2) of the three wires, or two wires (3, 4) are bent at their free ends about parallel to the metal strip (1) longitudinal direction. The metal strip is placed on an assembly device. A free end or wire in each group is automatically deflected, forming a hollow for the SC chip. The chips (5) is positioned and adjusted between the contact wires, and the deflected springly wire is released. The metal strip with the chips is then soldered and insulated.

Title: Electrically fired detonator for explosive charge - has ceramic insulated housing with carbon deposit current flow paths
Inventor: MELLOR DAVID JOHN
IPC: F42B3/12
Filed: 1977-07-12
Abstract: The igniter or detonator is initiated by electric current. The igniter housing has a chamber for an explosive charge.

Title: Electromagnetic induction liq. flow measurement system - uses electrodes immersed in liq. passing through rotating magnetic field
Inventor: FEITH BERNHARD DIPL ING
IPC: G01F1/00
Filed: 1977-10-01
Abstract: A channel down which a liquid is flowing at a speed v passes through a group of magnetic induction coils (SP1-3) arranged at 60 deg. to one another. They generate a rotating magnetic field. Linear electrodes (LE) project into the liquid sump (FS). The difference between two sine voltages (Uv1, VA1) appears on the electrodes with a left-rotating field and the sum (Uvr, UAr) for right rotating field. 1V1 = Uvr and UA1 = UAr for sufficiently high frequencies. The zero frequency limits of these values give a speed proportional voltage (UvO) and a cross-Section dependent voltage (UAO).

Title: Air heater for hair drier - has wanted temp. profile attained by appropriate spacing between heating wires loops
Inventor: MEYWALD KLAUS
IPC: H05B3/16
Filed: 1978-01-21
Abstract: The air heater, for e.g. a hair drier, has the pitch of its meandering heating wire chosen to produce a wanted temp. distribution in the output air. For example, loops closer together at the sides than at the centre produce hotter air at the sides. The spacing between loops may be inversely proportional to air speed. In this way a uniform temp. distribution may be achieved and the heating element prevented from attaining excessively high temps. in the low air speed regions.

Title: Purificn. of esp. oil polluted water - by upflow through bed of elastically deformable particles regenerated with raw water
Inventor: TOEROEK GABOR
IPC: B01D37/03
Filed: 1978-05-23
Abstract: Process comprises adding a flocculant to the water which is then pumped through a filter bed to trap the flakes etc. Periodic compressed air turbulence and rinsing are used to regenerate the filter bed. The filter bed is composed of elastically-deformable particles through which rising water is filtered. The degree of filtration is adjusted by regulationg the speed of flow of water into the filter bed. This alters the compression exerted upon the elastically deformable particles and hence the pore size of the bed. The pollution of the prefiltrate and/or the purity of the filtrate are pref. monitored intermittently or continuously by automatic equipment. Regeneration of the filter bed comprises using unfiltered water from the filter chamber assisted by agitation of the bed particles with compressed air. Used for filtration of polluted water, esp. oil-polluted water, to give a standard of purity suitable for drinking.

Title: Monitoring of code signals transmission from telephone channels - testing wire groups and channels and signalling results to central part during TDM transmission
Inventor: MUELLER HELMUT ING GRAD
IPC: H04M3/24
Filed: 1978-10-18
Abstract: The channels to be monitored cylically follow each other and connect a central part with code signal converters individually allocated to the channels in a signal converter unit. The latter is provided in a TDM transmission system between an interface at the exchange side and a multiplex unit. A test is made for break of wires in a wire bunch for code signal transmission from the central part to the channel signal converters. The test is made during transmission by one of the telephone channels. The channels are tested when signals are transmitted from the central part to the channel converters. The test result is signalled back to the central part. Faulty transmission on the loop between the peripheral and central components of a code converter caused by earthing or faulty switch contacts is thus detected.

Title: Glass pane carrier frame - with PVC antislip lining on bottom and rear guide rails
Inventor: JUERGENS WALTER DR ING
IPC: B65D85/48
Filed: 1978-12-18
Abstract: Parent patent described a transport frame for large panes of glass as required, for example for the windscreens of motor vehicles. It is now suggested to fit the bottom carrier rails with an insert of a material which prevents the glass panes from sliding. The lining is preferably made of anti-slip PVC extrusion with two slots on the sides which engage the top inward flanges of the bottom carrier channel. A similar PVC lining is applied at the tube against which the glass pane carrier leans. This prevents damage tot eh glass panes and is safer in case of vibrations than bosses in the carrier rails.
