Title: Cleaning products from coal gasification under pressure - by partly recycled tar oil in venturi scrubbers in series connection
Inventor: HOELTER HEINZ
IPC: C10K1/18
Filed: 1975-02-06
Abstract: Gas produced by the gasification of coal under pressure is purified using tar oil which is sprayed into the gas in several scrubbing stages. The temp. in the stages is so controlled that in the first stage a fractionation of the tar-contg components takes place with the injected wash oil. The subsequent stages effect a condensation, agglomeration and separation of the ballast constituents (tar, dust) from the gas stream. Special treatment for the wash water which is required before it can be discharged into the drainage system is obviated, as is temp. drop and reduction in gasification caused by wash water.

Title: Sintered hard metal tools based on tungsten carbide - where high impact resistance is combined with high wear resistance
Inventor: IWENSEN WLADISLAW A
IPC: C22C1/05
Filed: 1976-02-20
Abstract: Process for mfg. sintered hard metals based on tungsten carbide, by redn. of tungstic oxide in hydrogen to obtain metallic tungsten, which is then carburized at 1800-2400 degrees C to form tungsten carbide which is mixed and milled with a metal binder, then pressed and sintered. The novelty is that the WO3 is first reduced to 750-1300 degrees C. to obtain WO2 which is then reduced at 1000-1600 degrees C to obtain metallic tungsten. Used for mfg. upsetting-, cutting- and boring tools. The tungsten carbide produced by this process possesses high wear resistance combined with high resistance to impact loads, a combination hitherto unobtainable. The plastic deformation of fine and medium grained material (0.5-1.5 mu m and 2-3.5 mu m) is increased two to four times. The improved impact resistance is due to the formation of a complete crystal lattice structure with uniform, small grain size and without irregular inter growth.

Title: Electrohydraulic servo steering valve - has valve body operated by force from magnet coil acting on ground plate
Inventor: LANG ARMIN
IPC: F16K31/06
Filed: 1976-04-29
Abstract: The electro hydraulically operated valve is esp. for servo assisted steering. Breakdowns caused by impurities in the hydraulic fluid are reduced with introduction of progressive input current/oil output flow characteristics instead of linear. The magnetic force is produced by a coil (3) with a ground plate (4) connected to the coil by a push rod (6) which operates in a cylindrical channel (5) and carries on its other end a valve body (10). The progressive characteristic is achieved by using a pot shaped magnet (1) instead of a permanent magnet. At a constant air gap (s) the magnet produces a force squarely proportional to the current through the coil.

Patent DE-2628354-A1 (DE)
Title: Amino-peptidase and bleomycin hydrolase inhibitor bestatin - produced by aerobic cultivation op Streptomyces strains e.g. strain MD976-C7
Inventor: UMEZAWA HAMAO
IPC: C12P21/02
Filed: 1976-06-24
Abstract: Bestatin of formula (I) and its acidic salts are new. Bestatin is produced by cultivation of a bestatin-producing Streptomyces in a C- and N-contg. nutrient medium under aerobic conditions. Bestatin has substantially no antibacterial activity, but it shows weak inhibition of cell (including tumour cell) growth in mammals and strong inhibition of aminopeptidase B, leucine aminopeptidase and bleomycin hydrolase. On account of its inhibition of bleomycin hydrolase, bestatin strongly synergizes the antitumour effect of bleomycin. It can therefore be used in combination with bleomycin for the treatment of squamous cell carcinoma, and in the analysis of biological functions and disease processes.

Title: Combined digital and analogue display - has final digit replaced by light diode chain for max. and min. indication when tuning for resonance
Inventor: SPINNER GEORG DIPL ING DR ING
IPC: G01R13/40
Filed: 1976-11-11
Abstract: The combined digital and analogue display system is esp. suitable for measuring applications. It is adapted for systems where adjustment to a minimum or maximum value is required, as in tuning for resonance. The display system is driven from conventional digital electronic circuitry so that the read-out is in digital form, with the exception of the last digit or last two digits. The signals corresponding to these positions are used to drive analogue indicators so that an exact adjustment to a minimum or maximum absolute value may be readily made. The analogue display may take the form of a number of individual light-emitting diodes or liquid crystal elements arranged in a circular or spiral pattern. Alternatively, a column scale with apparently moving light spot may be employed.
