Title: Electrodeposition of metals
Inventor: ARNE WALLINDER JOHN
IPC: C25C7/06
Filed: 1968-10-31
Abstract: The plating current is controlled according to the polarisation voltage at the cathode, and the aim is to keep this constant. The A.C. supply is transformed and a full wave rectifier yields a D.C. supply which passes through a regulator. A solid state amplifier with a high resistance input load controls the regulator. The regulated D.C. is fed to the anode and cathode of the bath. The amplifier input is connected to a supply electrode in the form of a metallic probe immersed in the bath.

Title: Adsorption and retrieval of mutually react- - ive components of a gaseous mixture for rev
Inventor: KLOBE MARTIN
IPC: G01N30/30
Filed: 1969-01-11
Abstract: The individual component gases of the mixture are passed through partial fillings of selectively adsorptive material in a separating column. A ring oven surrounding a part of the column may be used to create a constant temperature gradient in that part of the column. When the gases have been adequately adsorbed, the system may be put on reverse flow and the gas components extracted individually and in turn by moving hte ring oven over that section of the filling into which the individual gas has been adsorbed. An inert gas is passed through the column during this phase.

Filed: 1969-03-20
Abstract: Opaque plastics film of up to 2 mm thickness and contng. 1 to 25% by wt. of inert filler particles up to 20 microns dia, is stretched to cause the particles to produce ink retentive rough surfaces and cause the film to become opaque. A fluid ink compsn. comprising a synthetic thermoplastics resin binders, an oil incompatible with the binder, colouring matter and a volatile organic solvent, is applied to the film surface in a thin layer and the solvent evaporated to bond the compsn. to the foundation.

Title: Indicator for showing decomposition of substances - such as foods or medicines
Inventor: MUELLER FRITZ PROF DR
IPC: G01N31/22
Filed: 1971-08-17
Abstract: Indicator for the non-destructive evaluation of the degree of decompsn. of chemically defined substances (e.g. medicines or foods) comprises a combination of substances with known reaction mechanisms (e.g. ester hydrolysis) with temp.-dependent consumption of a readily detectable reactant. The indicator can e.g. consist of 1 x 10-2m ethylcrotonate, 2.5 x 10-5m thymolphthalein and 3 x 10-4m hydroxyl ions. The degree of decompsn. of the ethylcrotonate can be determined by the change in colour of the thymolphthalein. The indicator is packed with the substance to be checked at the beginning of manufacture or storage. Temp.-dependent decompsn. can be determined from the amt. of readily detected reactant consumed, thus avoiding the need for chemical analysis of the medicine or food etc.

Title: Aluminium electrolysis anode - made by vibratory - pressing
Inventor: HASS WYNN M
IPC: C25C3/12
Filed: 1972-07-19
Abstract: The anode is produced by the material being first poured into a vibratory hopper mounted on a fixed mould frame and surrounded by a vertically displacable mould. The mould is then raised until the carbon fills it up, the hopper being withdrawn. A ram is lowered onto the C surface with vibratory compaction of the C taking place. This is assisted by the simultaneous identical speed lowering of the mould and ram, the compacting pressure being maintained just sufficiently high to hold the material in the mould, vibration being ended on removal of all entrapped air. After this a raised compacting pressure is applied by the ram to consolidate the compact and impress the ram face contours onto the top of the compact. After completion of pressing, the mould is lowered and the anode block is removed from the die plate. The method yields a very uniform anode block without density gradient.

IPC: C21B7/18
Filed: 1973-03-30
Abstract: A fabricated bell for charging hoppers on blast furnaces etc. has self-locating wear-resistant segments which can rapidly be replaced without removing the bell from the furnace. The bell-frame consists of rings to which T-section ribs are welded to form a cone, and the wear-resistant segments are laid on top of the ribs to form the upper surface of the bell using e.g. twelve segments. The top of each segment has an inverted U-slot which hooks into a groove at the top of the bell frame; a hole is also provided in the top of each segment so that they can easily be lifted off the frame. The bottom edge of the segments rest in a groove at the upper edge of the bell-seal. A surface-hardened wear-resistant steel is used for the segments; when they are worn they can be lifted off the bell and allowed to drop into the blast furnace; new segments can then be on the frame.

Title: Stable, durable and printable camouflage nets - polyethyleneterephthalate fibrous network sandwiched adhesively between fluorine-satd. biaxially stretched polyethyleneterephthalate films
Inventor: VON BLUECHER HUBERT
IPC: F41H3/02
Filed: 1973-07-27
Abstract: A lattice or mat of fine polyethyleneterephthalate fibres glued together in bundles is stretched above a film of polyethyleneterephthalate whose valencies have been saturated with fluorine. The two layers are led together through a wide slit die to a drying chamber into which is introduced a sparingly-flammable elastomer e.g. Fluorell (RTM), Viton (RTM) at 220 atmos. The surface of the lattice and the film are completely covered with elastomer whereby the non-slip coating on the lattice is dissolved by the volatile solvent, e.g. a ketone, of the elastomer. The film and lattice are brought together in the drying chamber and the volatile solvent is removed by a hot air stream. A top layer of fluorinated polyethyleneterephthalate film is applied and the whole is compressed in a heated laminating machine. At a cylinder pressure of 15 kp/cm2 and at 170 degrees C, the separate fibres of the lattice spread out to a flat network and bond intimately to the enclosing films. The prod. so derived is allowed to rest rolled up under strain for 70 hours before applying the required base colour. Known camouflage nets, based on polyamide fabrics coated with olive green PVC pastes have the disadvantages that the PVC plasticiser migrates, befouls the surface of the fabric, alters the infra-red emmission values of the organic pigments and quickly imparis their effectiveness. This invention increases life-span of camouflage nets, permits mechanical printing of camouflage patterns and simplifies storage.
