Patent DE-2738839-A1 (DE)
Title: Plasma etching metal coated substrates - by using a reaction gas composed of oxygen and carbon tetra:fluoride
Inventor: HASLER BARBARA
IPC: H01L21/3213
Filed: 1977-08-29
Abstract: In the prod. of semi-conductors in which substrates are coated with Cr or Mo or W and covered with a mask, which is then etched to form the required structures, etching is carried out by using a plasma of a reaction gas which consists of a mixt. of gaseous O2 and CF4, pref. 90% O2 and 10% CF4. Plasma etching is performed at a pressure inside the vessel of 0.1-10 torr. The mask is composed of Al metal. Method is more economical and does not present health hazards as the reaction gas is free of Cl gas. Safety measures are not necessary and the reactor can be made of less costly material. Used for the prod. of semi-conductors.

IPC: B01F7/18
Filed: 1978-08-11
Abstract: Plastics granulate or liq. materials are mixed continuously by removing part of the finished end prod. at the discharge point for recirculation with the supplied starting material. Starting material cannot be discharged in an unchanged state as it is subjected to preliminary mixing at the inlet to mixer. Specifically the mixer has a feed hopper which terminates in a frusto-conical portion disposed within a frusto-conical portion arranged for reception of the recirculated portion of the end prod. Portion of the end prod. is recirculated by an adjustable guide device disposed at the outlet of the mixer.
Patent DE-2842551-A1 (DE)
IPC: B29C45/56
Filed: 1978-09-29
Abstract: In the process for producing plastic mouldings the pressure acting on the composition is changed, after the plastic composition is filled into the mould and after the mould is closed, during the solidification period, in order to prevent an orientation of the molecules and of the filler particles in the plastic composition. This pressure change takes place by changing the mould clamping force. In this process the mould clamping force can be alternately increased and reduced.

A second transistor (T2) is inserted in the collector circuit of the emitter follower transistor (T1), its base coupled to its collector via a resistor (R2). The latter has the same resistance as the internal resistance of the amplifier. The emitter of the second transistor (T2) is coupled via an internal voltage source (Ui), or via a transistor-diode potential shifting circuit, to the input of the amplifier (V). The constant compensated output voltage (UA) has the same amplitude of the latter internal source (Ui), or potential shift.

Title: Linen dryer with open and closed blowing circuits - using segmented rotary moisture extractor adsorbing and desorbing alternately
Inventor: RENNEBECK KLAUS ING GRAD
IPC: D06F58/24
Filed: 1978-11-29
Abstract: An extractor consists of a rotor having a very large surface capable of adsorbing moisture. It is formed by a honeycomb structure of synthetic profiles or sheets or of paper reinforced with rags and bonded with synthetic adhesives, and streams of air flow alternately through its segments, for the drying of textiles and esp. items of linen. In a open circuit, outside air is drawn into the machine and is blown through the moisture extracting rotor back into the atmosphere. Separate fans blow air in a closed circuit through the items of laundry, through the moisture extractor and round again; heat being applied to at least one of the streams of air. The exploitation of latent heat makes very considerable savings of energy possible, 10% of the amount previously required being sufficient.

Title: Rail guided movable partition sections temporary storage - involves rail sections moved by partition sections outside their area
IPC: E05F15/638
Filed: 1979-01-19
Abstract: As used in a rigid-sectioned room-dividing partition wall, elements hung on a main rail, to travel separately, are accommodated when slid to the side in movable rail sections sited close together across the main rail. The rail section for accommodation of the wall element concerned is movable into its accommodating position, as an extension of the main rail, by the wall element itself, which is still outside the rail sections area. A magazine carriage to hold the rail sections can be driven by a wall element moved on the main rail, via a conveyor gear unit. This permits controlled guidance of the carriage into exact position relative to the main rail.

Title: Planetary skew rolling mill for mfg. tube from hollow ingots - where ingot is driven over stationary conical mandrel so tube has larger external dia than ingot
Inventor: BRETSCHNEIDER ERICH
IPC: B21B19/08
Filed: 1979-03-16
Abstract: A hollow ingot with a relatively small external dia. and thick wall, is rolled over a stationary mandrel to produce a tube with an external dia. larger than the initial ingot, and with a thinner wall. This result is achieved by using the planetary skew mill in the reverse direction, i.e. opposite to the conventional direction employed to reduce the external dia. of an ingot when mfg. a tube. The mandrel is pref. mounted on a rod and consists of a cone increasing in dia. in the direction taken by the rolled tube leaving the mill. The overall result is that relatively short tubes of large external dia. can be made on a planetary mill normally used to mfr. long tubes with a small external dia.

Title: Implant which can be used as replacement for spongy bones - is built up from tolerated fibres which are implanted in bone cut=out
Inventor: KEMSSGE JOACHIM PROF DR MED
IPC: A61F2/00
Filed: 1979-03-17
Abstract: A network which is stable in structure, and space-filling is constructed from threads or fibres which will not be rejected by the body, and can be implanted as a replacement for spongy bones. The threads or fibres may be of metals, metal alloys, ceramics, carbon and/or synthetics. At their crossing points the threads are joined by welds, etc. A shaped object may be produced from the network by pressing or embossing and immediately after cutting or dividing, forms the implant. The network may be shaped into a wedge, square, disc, etc. or a core with an envelope. The process develops implantation techniques so that after a short time the defective bone structure can stand the stresses encountered during normal use.

Title: Wind power turbine with vertical axis - is connected to medium site generator for providing power for single houses
Inventor: SCHWARZ HERBERT
IPC: F03D3/04
Filed: 1979-06-11
Abstract: The turbine consists of deflector plates (3), preferably nine or eleven in number, and these have an angle of incidence (4) to the central axis of 103 degrees. These plates are in a housing with base and feed, through the centre of which is a vertical rotor axle (6) which serves as a drive shaft for connecting to a generator. On this shaft (6) are mounted at least four rotor blades (7) with sail fins (8) which in single or multiple form, are joined to the rotor (6) by rigid spars (9). The rotor (6) is mounted in bearings top and bottom. The wind always enters in three compartments regardless of the direction from which it may blow, due to the deflector plates (3). This construction prevents the wind from acting in the wrong direction on the rotor blades.
