Title: Nozzle for spraying flat jet of paint or lacquer - forms spinning spray cone impinging converging cone wall of slot nozzle
Inventor: ROTH HEINRICH
IPC: B05B1/04
Filed: 1975-07-17
Abstract: The nozzle head for paint or lacquer spray gun is operated only by the hydraulic pressure from the paint itself, e.g. by electromagnetic piston pumps or hydraulic pumping units. It comprises a swirl nozzle (4) mounted in an internally cylindrical hollow nozzle holder (2) in such a way that the paint passes through supply openings into an outer annular chamber (4d), then inwardly into tangential slots. The tangential liquid columns impinge on each other becoming finely atomised into particles which tend to flow out in the form of a spinning spray cone, but which after impinging onto the inwardly tapered cone wall of the slot nozzle (1) can only flow out through the wide longitudinal slot (1b) in the form of a flat jet. All the supply channels (4a, 4b) in the swirl nozzle and the tangential baffle channels (4c) have dimensions which allow constant through-flow even in a case of very high viscosity paint and large solid or semi-pasty suspended particles.

Title: Gallium winning from alkali solns. - by redn. with aluminium dissolved in liq. gallium stirred by alternating magnetic field
Inventor: IWANOWA RAISA W
IPC: C22B58/00
Filed: 1975-08-19
Abstract: Gallium is extracted from alkali solns. using electrochemical redn. with the aid of liq. metals. Redn. occurs in an alternating electromagnetic field. The process is pref. undertaken using (a) liq. Ga; or (b) contg. 0.05-0.5% Al and possibly 0.1-10% Zn. The liq. metal may be polarised to form a cathode, using direct current of 0.001-0.1 A/cm2. If the alkali solns. contain other substances which would impede the extn. of Ga, the substances are pref. reduced and removed from the soln. by settling or filtration prior to Ga extn.; the reduced substances can be pptd. by adding an alkaline earth element. Used in winning Ga from solns. obtd. in processing bauxite or nepheline. The Ga can be used e.g. in semiconductor cpds., dental alloys, or as conductors of heat or electricity. There is continuous prodn. of high purity Ga, where the magnetic field disturbs the film on the liq. metal cathode, improving the yield of Ga.

Title: Forepole board for tunnel or roadhead - has conical shape with varying section height, and edge channels for linking
Inventor: REUTER HARALD
IPC: E21D9/06
Filed: 1975-09-17
Abstract: The forepole board for tunnels, headings, underground roadways, conduits etc. is cantilevered forward hydraulically to support the roof during subsequent excavation or channel boring operations. The board is part conical as the sectional height varies lengthways along the board. The boards are linked in rows and are twisted round their long exes to obtain parallelism and allow the boards to be inserted wedge-fashion with the non-conical edge leading. The boards are made from commercial steel flats, and have symmetrical cross-section. The boards can be rotated round their transverse axes to provide variable section, and in this way obviate the need for left hand and right hand board designs.

Title: Furniture joint with round rod shaping veneered corner - has chamfers on groove for rod which abut so quick setting glue can be used
Inventor: MERKEL KARLHEINZ
IPC: B27F1/00
Filed: 1975-10-31
Abstract: The already veneered board is cut away to the profile of the two sides of the joint, leaving only the veneer (6) to connect the two halves; it is then wrapped round a rod (26) and glued to it. The glue used for this must not mark the veneer. To allow a quick-setting glue to be used, a rod thinner than the boards it joing is used. Slow-setting glue will be used beside the veneer, but on the opposite (inner) side of the joint the boards meet each other directly (over a small gap (28)). Quick-setting glue applied along the small gap establishes the joint firmly within a few seconds: it can then be set aside for the slow-setting glue to hardenM without having to be kept in clamps throughout this time.
