Patent DE-1906755-A1 (DE)
Title: Manu of thin film structures on substrates - and use of such structure, as photomasks
Inventor: FRIEDRICH KRIEGER DIPL-ING
IPC: G03F1/68
Filed: 1969-02-11
Abstract: First of all a layer of material which can easily be removed is deposited on the substrate.

The structure may be used as a photomask for integrated circuit manufacture or alternatively as an electrical conductor.
Patent DE-1932004-A1 (DE)
Title: Automatic analyzer for dissolved gases in - liquid samples
Inventor: NATELSON SAMUEL
IPC: G01N7/14
Filed: 1969-06-24
Abstract: A positive displacement pump with an accurately defined stroke controlled by a servo motor delivers a measured quantity of the sample to a reaction chamber, fitted with a magnetic stirrer, into which various reagents may be fed in turn from a multistation feeder system, the volume of free space in the reaction chamber being fixed. One station is connected to a closed chamber containing a gas absorber and others allow a vacuum to be drawn in the reaction chamber. A recording pressure gauge determines the pressure difference between the partial pressure of a gas liberated by treatment of the sample with a reagent after the drawing of the vacuum and the pressure remaining under the same volume conditions after the chamber is connected to the gas absorber. This differential pressure is the scale of measurement for the gas content of the liquids.
Patent DE-1937024-A1 (DE)
Title: Production of knitted goods
Inventor: GIBERSTEIN BERNARD
IPC: D05B37/10
Filed: 1969-07-21
Abstract: Device for the automatic production of women's tights, from two identical stocking shapes, which are automatically cut open, and sewn to form the finished article. As hand work on this operation can take from 10% to 20% of production overheads this reduces costs, increases productivity and provides a standard quality of output. An electric heated cutting device is mounted on the form holding the stocking, operated through a resistance, which can be automated. Current can be passed to it for operation either after the stocking has been shaped or during processing. As the stocking on their forms are cut in matched symmetrical lines, they can be automatically stitched together to form the finished tights, and the sewing machines, if necessary, can be linked to the cutters to control the operation.

Title: Metal chloride(s) prodn - by chlorination of finely dispersed metal(s) suspended in inert gas
IPC: C01F7/58
Filed: 1970-07-01
Abstract: Temp. of the process can be easily controlled by introducing a suspension of a finely divided metal(s) into a reaction chamber, where Cl2 is also introduced.

Title: Making flat brushes - by winding filaments helically onto holders mounted on revolving drum
IPC: A46D3/05
Filed: 1970-07-28
Abstract: A method for manufacturing brushes, consisting of holders, bristles and capping pieces, with single bristles at defined spacings, esp. of plastics, is carried out by winding one or more endless filaments helically around a revolving drum, on which the brush holders are mounted; the capping pieces are then applied to the holders, and the assemblies bonded together, e.g. by two-component adhesive or ultrasonic welding, then the bristles are cut along planes parallel to the axis of the revolving drum, so that a number of separated brushes are produced. The advantage of the system is that single layer, double-sided flat brushes with bristles at defined spacings and accurately cut to length can be produced in a single operation without further trimming.

Title: Continuous load switching for step-transformers - involves thyristor rectifier bridge with firing controlled via four pulse circuits
Inventor: RICHTER HEINZ DIPL ING
IPC: H01H9/54
Filed: 1973-06-20
Abstract: For the continuous load switching for step-transformers the two ac-points of a rectifier bridge are connected to the two arms of the tap selector. The rectifiers of the bridge are thyristors. The two dc-points of the bridge are interconnected via two diodes in series, to the centre of which a load line is connected. The blocking voltage across the diodes is used to feed control circuits which fire the thyristors. Each of the four switching circuits generates in its monostable relaxation oscillator pulses for firing one thyristor. The relaxation time can be continuously altered within suitable time intervals by varying the value of the setting resistors. By inserting an inverter into one of the two signal voltage lines from the diodes a common reference potential is obtained for all four pulse circuits which also have a common power supply. By paralleling a diode to each setting resistor a very small recovery time is achieved. The advantages claimed are small number of components, increased operating reliability and economical working.
