Title: Moving picture display from ultrasonic scanner - is by using rotating drum with multiple scanning heads
Inventor: KRETZ CARL DIPL ING
IPC: G10K11/35
Filed: 1976-02-21
Abstract: The drum (2) carrying the scanning heads (4a-4f) rotates inside a fixed drum (1) containing an ultrasonic conducting fluid (3). The space between the drums is kept to a minimum in front of the currently operative head (4d), to reduce reflection effects. The output of the scanner is picked up by a brush contact (7) and displayed on a cathode-ray tube. As each scanning head in turn moves into the scanning area (8a, 8b) the contact (7) transfers correspondingly. The use of several heads instead of one improves the resolution of the image for a given CRT frame frequency. A second set of scanning heads, mounted between those of the first set and on the same drum, could be used to provide an alternative picture of the same subject.

The fleece is suitable for use as a cover for cellulose wadding used for hygienic or medical purposes. In an example, the fleece is a thin wide fibrous bandage of single or multi-layer cellulose wadding with a density of 23 g/m2, to which is glued a polyethylene film with a density of 20 g/m2.
Patent DE-2607684-A1 (DE)
IPC: B22D7/02
Filed: 1976-02-25
Abstract: To produce composite workpieces from two different grades of steel, a solid object of steel of one grade is coated with a 0.3 to 1 mm thick layer of a nickel-chromium-boron-silicon alloy. This layer is sprayed on, for example by flame-spraying. The object is then inserted into a casting mould and molten steel of the other grade is cast around it. The alloy of the coating has a substantially lower melting point than the steels. The coating can be applied in a simple manner and effects an intimate joint between the solid steel and the solidifying steel.

Title: Radial spherical membrane pump - consists of annular pump housing with fixed bearing brackets to accept drive shaft with balls
Inventor: KOWALZIK HARTMUT
IPC: F04B43/14
Filed: 1977-01-20
Abstract: Radial spherical membrane pump consists of an annular pump housing on both sides of which bearing brackets are fixed to accept and support the drive shaft with the displacement balls. The inside of the pump housing has a ring-shaped form of arc section cross-section over which an elastic hose-type membrane is stretched in a pressure tight manner. By sticking or screwing to the pump housing at a precisely defined position, the elastic membrane seals the inlet orifice from the outlet orifice and thus allows the pumping. The displacement balls, which are carried by the drive shaft, are guided in radial cylindrical bores.

Title: Regeneration of a polymeric adsorbent - by contacting with a supercritical fluid to remove the adsorbate by dissolution
Inventor: MODELL MICHAEL PROF
IPC: B01J20/34
Filed: 1977-04-15
Abstract: Parent patent describes the removal of organic impurities from water using an adsorbent and sepg. the adsorbate from the adsorbent by bringing the adsorbent contg. adsorbate into contact with a supercritical fluid which is a solvent for the adsorbate, so that the latter is dissolved and removed from the adsorbent. In this addition (a) a polymeric adsorbent (PA) is contacted with a stream of water contg. the organic material (OM) so that the OM is adsorbed by the PA; (b) the PA contg. OM is contacted with a supercritical fluid so that the OM dissolves in the supercritical fluid; (c) the supercritical fluid contg. OM is sepd. from the adsorbent; (d) the supercritical fluid is transformed by a physical treatment into a non-solvent for the OM and a 2-phase system is formed; (e) the non-solvent supercritical fluid phase is sepd. from the OM phase; and (f) the supercritical fluid is reconverted into a solvent for the OM by a physical method. Used to remove impurities e.g. pesticides, insecticides detergents, explosives or biological substances from waste water, coloured matter or from the bleaching waste from a pulp mill. The OM is easily sepd. from the adsorbent by the supercritical fluid without causing any physical or chemical change in the OM. Samples can be therefore be analysed to determine the exact amount of impurities present.

Title: Lock with interacting eccentrically rotating discs - has release lever permitting adjustment of key setting
Inventor: BUDACH HEINRICH
IPC: E05B37/12
Filed: 1977-06-08
Abstract: The lock comprises a pair of metal plates bearing the spindles of a series of rotatable metal discs. The discs may be eccentrc to their rotational axes or have segmental recesses or flats in their edges. Two discs (5, 6), eccentric to their rotational axis, are turned independently by a key. When locked, the two discs (5, 6) overlap a third disc (1) preventing it from sliding axially on its spindle. When unlocked, the third disc (1) may be slid out of the plane of a fourth disc (7), which is eccentric, and may be rotated to release tha latch (10). A lever arrangement releases the sliding disc (1) for the purpose of adjusting the key setting.

Title: Collector installation for solar energy - has skeletal structure with rows of adjustable reflectors focussed on common absorbers
Inventor: WILDENRPTTER KARL DIPL ING
IPC: F24S23/74
Filed: 1977-08-26
Abstract: The complicated and expensive erection work connected with the assembly of a large number of collectors for the energy of the sun, esp. e.g. the large number of pipe joints necessary, is simplified and reduced considerably. A collector platform formed from light structural details is set up, inclined to the vertical and free to rotate on a vertical axis. In this the reflectors are arranged in rows side by side; the focussing line of the reflectors in one row lying in a straight line, in the proximity of which a common absorber for the row is positioned. The row of reflectors thus forms a long parabolic mirror with a length which is the multiple of a single mirror and instead of separate abosrobent tubes, one long tube can be used.

Title: Amino naphthalene sulphonic acids prepn. from corresp. nitro cpds. - using mostly used Raney nickel under specified conditions
Inventor: BARTH OTTO
Filed: 1977-10-25
Abstract: A process for prepg. aminonaphthalene sulphonic acids by catalytic hydrogenation of the salts of nitronaphtalene sulphonic acids comprises the following. A mixture of used Raney nickel catalyst and fresh Raney nickel catalyst is suspended in water and/or an aq. soln. of the hydrogenation product. The suspension under 100-300 bars hydrogen pressure is heated to 100-180 degrees C. At this temp. a soln. or suspension of the nitronaphthalene sulphonic acid at pH 6-9 is added in amt. such that the content of the nitro cpd. in the reaction mixture is not above 5% of the total weight and the final concn. of aminonaphthalene sulphonic acid is 5-40% of the total reaction mixture. The products are intermediates in the prepn. of dyes. The process gives a 10% yield increase compared with previous processes (95-99% and a space/time yield of 1-3 kg. amino cpd./l. capacity/hr.); also the bulk of the catalyst may be recycled and a faster reaction rate is obtained.

Title: Tube bending fixture for producing helical coil - includes stationary torque head and mobile coiling mandrel
IPC: B21D11/06
Filed: 1977-10-26
Abstract: A helical coil tube (1) is produced with the help of a tapered coiling mandrel (5), and a fixed coaxial clamping head (7) that produces the coiling torque. After one tube end is located by the off-centre clamp (3) on the rotor head (7), heat (6) is applied to the tube to ease the bending operation. A tube guide (9) in the mandrel support (8) feeds the tube onto the mandrel (5) tangentially and at the helix angle. The mandrel is then moved away from the fixed torque rotor (7) at a rate that is equal to the growth rate of the helix coil (1).
