Title: Motor driven compressor with cooling fan on motor shaft - has compressor facing at cylinder level and compressor shaft driven via V=belts
Inventor: BECKER ERICH
IPC: F04B39/06
Filed: 1976-08-23
Abstract: The compressor (3) has one more cylinders (5) and is driven by a motor (2) and cooled by a fan impeller (7).

Title: Determination of cyanide ions in aq. solns. - using tube contg. cellulose powder impregnated with gold complex
Inventor: GLEISBERG JOACHIM DR
IPC: B01J20/22
Filed: 1976-09-10
Abstract: Quantitative determn. of CN- ions in aq. solns. is carried out using a tube contg. a sorbent, over which the soln. is passed. The sorbent comprises cellulose powder impregnated with an Au3+ complex of Na 1-nitroso-2-naphthol-3,6-disulphonate (NNDS). The cellulose powder is pref. diethylaminoethyl or triethylaminoethyl cellulose, opt. mixed with neutral cellulose powder in a ratio of 1:0-30. The sorbent can be prepd. by swelling the cellulose material with H2O, stirring with a mixt. of a 1% NNDS soln. and a 0.5% HAuCl4 soln., filtering, washing with H2O, drying and grinding to 250 mu. The method is based on the fact than CN- ions decolorise the sorbent as the soln. passes through the tube, and the length of the decolorised zone is proportional to the CN- concn. in the soln. Most foreign ions (except sulphide) do not interfere at concns. below 50 mg/l, and CN- concns down to 5 mu g/10 ml. can be determined.
Patent DE-2643121-A1 (DE)
Inventor: NISHIMURA KENJI
IPC: B01J2/16
Filed: 1976-09-24
Abstract: The process consists of two steps and is repeated until the particles suspended in the fluidised layer have attained the suitable degree of moisture. The first step consists of spraying a liquid onto the particles, the second is the drying thereof. The apparatus comprises automatic control elements of the type shown in Figures 5 and 6 and in general a plurality of filters (10) in the upper part of the chamber containing the fluidised layer, in order to prevent the particles from escaping. To avoid blockage of these filters, it is expedient to incorporate a filter-shaking step, by which the filters are shaken to loosen any captured particles, by arranging for the draught regulating flap (11) to close the exhaust air duct from the chamber and thus to interrupt intermittently the suction effect of the suction blower (12). During shaking, both the spraying of the liquid and the fluidisation are stopped. This step can be used both in this cycle or in the drying cycle. <IMAGE>

Title: Mine gallery support channel framework - has bridging assemblies between channels, locked by two partly hooked securing devices
Inventor: HULISS FELIX
IPC: E21D11/26
Filed: 1976-09-25
Abstract: The framework for supporting the walls of nine galleries is made up of trough section members (2, 3) which can form arches matching the shape of the gallery. These trough members are secured to one another by U section bridging members (1) with cut-outs (29, 30) which fit over the beaded edges (7, 8) of the troughs and held in place by locking members which engage tubes (37) inserted through the arms of the bridging member. Each locking member has a U section inner part (22) with a hook (27) which grips one beaded edge (8). This is locked in position by a bolt (33) with a hooked end (21) which grips the other beaded edge (7). A pin (39) passes through a slot (38) through both the stem of the bolt (33) and the sides of the inner part (22).

Title: Continuous gasification of solid fuel in fluidised bed - with feeding of the fuel in a carrier gas stream
Inventor: ANWER JAMIL DR
IPC: C10J3/54
Filed: 1976-09-25
Abstract: In the continuous gasification of particulate carbonaceous material, esp. coal, the material is fed to the fluidised bed reactor in a carrier gas stream under conditions such that (1) the fuel with particle size up to 9.5 mm. is passed in at 3.2-32 kg/m3 carrier gas, which is at =538 degrees C, (2) pressure drop in the fuel feed pipe is kept = the absolute pressure in the gasifier, (3) velocity of the feed keeps the top of the bed at a given height and height ratio of the diluted gas zone to the bed of 3-10:1, (4) >=50% of the steam used is passed in at the bottom of the bed at =649 degrees C to fluidise the lower part of the bed, and (5) the fuel is gasified at 816-1316 degrees C and at below the softening point of the ash, to a gaseous prod. contg. CO and H2. Process is simple, requires no maintenance and effectively distributes the fuel in the fluidised bed, allowing equilibrium gasification conditions to be reduced rapidly. Fuel contg. volatiles, e.g. coking coal, can be used without pre-treatment, without agglomeration causing blockages or poor fluidisation. The fuel transport system requires few seals to withstand the reactor pressure and has no moving parts. The carrier gas participates in and assists gasification.

Title: Binder-free pressing of valve metal component such as tantalum - uses small amount of excess powder, supplemented by constant amount of fresh powder
Inventor: FAUSER WERNER DIPL PHYS
IPC: B22F3/02
Filed: 1977-02-23
Abstract: Process is for the pressing of e.g. tantalum sinter bodies. The powder is fed from a storage in exactly proportional amounts into a press to fill a die holder. Excess powder is returned to the holder via the storage in a cycle.

IPC: G01F1/00
Filed: 1977-07-13
Abstract: The open ends of a number of tubes (9) are immersed below the level (19) of the water in an overflowing water transport system. Air compressors (10) force air down the tubes and out of the open ends.
