Patent DE-2361056-A1 (DE)
Title: Increasing micro-organism growth rates in sewage installations - high strength magnetic fields are operated in all zones
Inventor: VOX WILHELM DR ING
IPC: C02F1/48
Filed: 1973-12-07
Abstract: The parent describes a method of increasing the growth rate of microorganisms in biological purification systems for sewage, by influencing the oxygen of the air introduced into the fluid or already existing in it, magnetically. In the patent of addn. the application of magnetic fields is extended to teh waste water inlet and/or the activated sludge and/or the air/oxygen injection equip. The time is seconds during which the magnetic fields are operated multiplied by the field strength in gauss is a constant K, which, depending upon the conditions is chosen between 25 and 1,000 gauss secs, - the field strength being relatively very high-between 100 and 200 times that of the earth's magnetic field. Electro-and/or permanent magnets are positioned in the sewage feed line (1), in the activated sludge tank (2), in the sludge feed bank line (4) and the air feed (5) together with the distributor filters (6) and operated permanently or temporarily, singly or in co-operation. The process applies the most appropriate fields in the correst arrangement relatively to the air input on the one hand, and for the best possible influence on the sewage water itself and/or the activated sludge on the other.

Title: Gas turbine for motor vehicles - has laval nozzle and a pressure reducing turbine but no heat exchanger
Inventor: JUSTUS SIEGFRIED DIPL PHYS
IPC: F02C3/32
Filed: 1974-03-20
Abstract: The gas turbine is used basically but not exclusively as a motor vehicle prime mover, and does not have a downstream heat exchanger in the high temperature region. The gas turbine has downstream convergent divergent nozzle through which more than half of the working gas is passed and accelerated above sonic speed. Cold air is passed through convergent divergent nozzles held within the main nozzle in the diagram. This air is accelerated to about twice the sonic speed and cold and hot gases are mixed in the mixer. A downstream pressure is generated in a recompression unit. A decompression turbine is operated with gas drawn from the cycle. This turbine cycle can be operated with argon and a nuclear reactor.
Patent DE-2413415-A1 (DE)
Title: Separate processing of fast and slow transients in voltage regulation - involves separate amppmpllplifier circuits for fast and slow transients before
Inventor: KERN OTMAR
IPC: G05B11/40
Filed: 1974-03-18
Abstract: The voltage signal from a communication line is passed through a retifier and then it is passed to amplification circuitry that processes the fast and slow transients separately. The high speed components are transmitted directly over a resistor and capacitor to a first amplifier. The slow speed components are extracted and processed over a second resistor and a second capacitor before passing to a second amplifier. The amplifier outputs are transmitted to a common line via a voltage divider arrangement. A potentiometer permits the influence of the slow speed components upon the output to be regulated.

Patent DE-2438589-A1 (DE)
Title: Domestic and industrial sewage treatment by activated sludge - with two-stage aerating under infinitely variable pressure
Inventor: MOSER FRANZ PROF DR ING
IPC: C02F3/00
Filed: 1974-08-10
Abstract: In an installation for the biological purification of domestic and industrial sewage using activated sludge, the effluent flows through a pre-clarifying stage to a secondary clarification tank with sludge separation, by way of a number of extensive aerating stages of such dimensions that the water flows through under pressure. These aerating stages are divided into two groups, the water flowing through being subjected to a higher localised gas pressure in the first than in the second. The gas pressure is infinitely variable and if gases with a similar oxygen content are used in both stages, the oxygen part pressure is increased in the first stage by intensifying the gas pressure, whereas, if the oxygen content of the gases for the two stages is different, the oxygen part pressure in the first stage is increased by raising the oxygen content of the gas supplied. Whilst having the smallest dimensions possible, the plant can be operated in the most economical manner according to the nature of the sewage being processed. In large installations, the reduction in pressure between the two stages can be effected by decompression turbines, so as to recover some of the energy in the system.

Title: Lancet for allergy and compatibility tests - is for rapidly easily obtaining a large number of regularly arranged lancing points
Inventor: BAUMGARTNER ERICH RUDOLF
IPC: A61B5/103
Filed: 1974-09-19
Abstract: The lancing instrument for allergy and compatibility tests comprises a wheel body (6) which is rolled over the skin and in which are radially guided spring-loaded (14, 15, 16) lancets (11). The latter are maintained in a radially retracted position by retaining means (5) and are releasable (5a) in a given rotary position during rolling for rapid radially outward movement independently of rotational movement of the wheel body. This causes the lancet tips (13) to project beyond a support surface (10) on the skin, pref. a peripheral surface of the wheel body into which lead radial channels (9) containing the lancets.

Title: Fixture for machining openings into frame profiles - has angle plate for holding machining template and guiding milling head
Inventor: EISENBACH BERNHARD
IPC: B23B41/00
Filed: 1974-12-27
Abstract: The fixture for milling and boring of opening into two walls of a profiled member at right angles to each other is used especially for machining of door and window frames made from aluminium or plastics profiles. Large openings are machined without using milling cutters of large diameter and hence the machine slides are not heavily loaded and low cutting power can be used. The fixture has angle frame whose angle corner accommodates a longitudinally sliding guide rod. This rod supports a sliding guide which in turn supports the milling head slide. The angle plate arm (2a) of the frame accommodates a copying template (12'). A copying stylus which can be arranged at either end of the milling head slide (6) and the slide guide (5) can be clamped on both rotated positions on the frame.

Title: Oxidn free molybdenum electrical contact - has coating of molydenum boride or molybdenum silicide
Inventor: POLITYCKI ALFRED DR ING
IPC: H01H1/021
Filed: 1975-05-02
Abstract: Molybdenum material for use in electrical contacts is coated with a film of molybdenum boride or molybdenum silicide to a thickness from 10 to 1000 nm. A boride film can be produced by sintering on amorphous boron powder in a vacuum to 900-1000 degrees C or by electrolysis in a fused state or by chemical vapour deposition. Silicide films are produced by exposing red hot molybdenum to H2 and Si Cl4 or Si H Cl3. This protects molybdenum contacts from oxidation even when no inert gas surrounds them. It is more effective than gold plating which may be porous and still cause oxidation.
Patent DE-2519824-A1 (DE)
Title: Crane load safety device - has coupling fitted with damper units which allow limited relative rotation between two hoist drums
Inventor: SCHNEIDERSMANN ERNST-OTTO DR I
IPC: B66D1/54
Filed: 1975-05-03
Abstract: The safety device protects against the fall of a load suspended from a crane, particularly a foundry crane; the load is hoisted and lowered by two coaxial synchronous winch drums equipped with safety brakes. A coupling between the drums allows a limited amount of relative rotary movement, the coupling halves bearing against each other via shock damper units (3, 4). Limit switches can be mounted on one or both coupling halves, giving an alarm in the event of relative rotation of the halves beyond a predetermined maximum angle from the central position. There can also be other limit switches stopping the drums and/or applying the safety brakes in such an eventuality.

Title: Surface treatment of plastic sheet - by spark discharge together with hot ozone- containing air
Inventor: LEEUWEN PETER VAN
IPC: B29C59/10
Filed: 1975-07-22
Abstract: The surface treatment is carried out by means of a spark discharge between two electrodes in an appts. in which >=1 of these is spaced from the plastic layer. This spaced electrode is constructed as a trough, the opening in which faces the plastic layer. A fan is connected to the trough to produce a difference of pressure therein relative to ambient pressure. Improves the efficiency of the surface treatment of the plastic layer by distributing a stream of hot, ozone-containing air over the surface.
