Title: Organic solvents recovered from raffinates in metal winning - where raffinate is stripped by steam in a scrubbing tower
Inventor: WIESNER PAUL
IPC: C22B3/26
Filed: 1976-12-04
Abstract: Organic solvents are recovered from raffinates used in the counter-current solvent extn. of metal ions in the wet treatment of ores. After removing the metal ions, the raffinate is stripped using steam and/or gas, and the organic solvent is recovered from the vapours. Pref. 0.5-5 wt.% steam and/or gas is used for stripping the raffinate, esp. in counter-current in a scrubbing tower; and after stripping, the raffinate is pref. cooled in heating raffinate which contains solvent, i.e. before stripping. The stripped raffinate is pref. returned to the ore leaching process. Used in many hydrometallurgical processes, e.g. for winning U, Cu, V, W, where metals are extracted from aq. solns. by organic solvents using liq. -liq. extn. Practically all the organic solvent can be recovered.

Title: Replacement hair inserted into scalp - is positioned by curved channels formed by noble metal threads
Inventor: BAERSCH GEORG
IPC: A61F2/10
Filed: 1976-12-11
Abstract: The replacement hair is fixed on the scalp. The hair is attached permanently and the living tissue does not reject it. Noble metal threads are inserted into the scalp. These threads are removed a few days later. Hair is pulled into curved channels - made by the metal threads - into the scalp. The metal threads are inserted so that the middle part of a thread is held in the scalp skin and front and rear ends of a thread project out of the skin. The metal threads can be in the form of a helix whose winding lower parts are held in the scalp. The windings are subsequently separated by cutting to form separate hooks. Metal thread dia. is slightly smaller than the hair strand dia. used.

Title: Transmission and reproduction of stereophonic sound - uses basic signal and two side signals radiated by three loudspeakers
Inventor: SCHERER PAUL DIPL ING DR ING
IPC: H04S1/00
Filed: 1976-12-31
Abstract: The device consists of a directional microphone unit with quickly rotating directional characteristic on the input side, and a reproduction side with loudspeakers in series with channel modulators synchronised by a pilot tone. Two LF sound voltages are derived from the sound signal. They are converted at the reproduction side to stereo signals, and converted back in channel modulators modulated in opposite senses in corresponding loudspeaker channels. The sum of the two AF voltages is added, and the sum voltage applied to the channel loudspeaker through a low-pass filter.

Title: Sectioned underwater reinforced concrete tunnel construction - uses guiding supports in bed channel below base level
Inventor: GAISER HERBERT DIPL ING
IPC: E02D29/073
Filed: 1976-05-03
Abstract: In reinforced-concrete underwater tunnel construction, front-sealed tunnel tubes (2, 3) are made by concreting one on to a previously completed one, inside formwork. They are then pressed forward along the gradients (4, 5) on a track in the bed, in rhythmic process depending on section length. Spaced guide and support units are fitted in a channel excavated in the bed, with their top bearing surfaces sited below the level of the channel floor. The top layer of this floor is displaced through the forwarded tunnel tube as far as the level of the bearing surfaces. Pressure may be controlled by flooding or pumping out the chambers in the tube.

Title: Agents for dissolving urinary calculi - contg. alkali salts of metabolisable organic acids, e.g tartaric acids, forming only weak complexes with calcium ions
Inventor: KNAPPWOST ADOLF PROF DR
IPC: A61K31/19
Filed: 1977-03-08
Abstract: New medicaments for dissolving urinary calculi in the human body contain alkali salts or a metabolisable organic acid which does not form a water-soluble complex with Ca ions or which forms water-soluble complexes with Ca ions which are substantially more strongly dissociated than those of citric acid (i.e. the acid binds Ca ions less strongly than does citric acid). The medicaments dissolve both uric acid calculi and calcium oxalate calculi. The alkali salt used does not cause marked dissolution of calcium oxalate deposited in the duodenum and small intestine, but after absorption it is metabolised to citric acid and cause dissolution of urinary calculi and elevation of urinary pH to ca 6.5-6.8. Pref. alkali salts are those of tartaric acid, and pref. dosage forms are efferscent tablets. In an example, effervescent tablets each weighing 3 g. contain 32.4 wt.% CH3COONa, 32.4 wt.% potassium tartrate, 15.4 wt.% KHCO3, 4.0 wt.% NaHCO3, 13.8 wt.% tartaric acid, and 2.0 wt.% MgO (specific surface 10 m2/g).

Title: Complementary volumetric inspection esp. of reactor pressure vessel - using internal and external test heads located by ultrasonic beam
Inventor: BORN FRIEDRICH DIPL PHYS
IPC: G01M99/00
Filed: 1977-06-13
Abstract: Test system (I) of a first manipulator is conducted along one face (typically inner face) of a vessel wall and simultaneously a complementary test system (II) of a second manipulator is conducted along the opposite face to a complementary position. An ultrasonic beam emitted from system (I) passes through the wall to be received by system (II). The resultant reading of the deviation of the position of system (II) from its ideal position is converted into a movement to correct its position. Both systems (I, II) are used for volumetric test operations, e.g. of the tandem or single-head type; alternatively or additionally, a tandem inspection system is formed by system (I) as emitter (or receiver) and system (II) as receiver (or emitter). Used for testing walls of vessels or pipes esp. ultrasonic testing of weld seams and adjacent zones. Partic. for the inspection of nuclear pressure vessels with a plated or similar surface zone of 20-30 mm thick. The arrangement of two measuring systems, with a sharply oriented ultrasonic beam to locate one system relative to the other, enables the entire surface area to be accurately covered, both systems being available for the ultrasonic tests. Total inspection time is reduced.

Title: Mould for continuous casting of metal, esp. steel - has transverse, chilled wall cooling interior of melt at the mould inlet
Inventor: WINKLER HELMUTH
IPC: B22D11/04
Filed: 1977-07-09
Abstract: The mould includes a cooled, tubular sheath and, for the initial cooling of the molten metal in the mould, the latter is (partly) closed near its inlet by a transverse wall (a) which cools the core of the melt; and a coolant flows through wall (a). Wall (a) is pref. inclined, or at 90 degrees, w.r.t. the longitudinal axis (X) of the mould. In some of the pref. mould designs, axis (X) is vertical and wall na) is a horizontal or sloping extension on the top of the mould; and the hollow wall (a) contains a baffle plate directing the flow of cooling water. In another pref. design, axis (X) is horizontal, and a vertical wall (a) completely closes the inlet end of the mould, the inlet for molten metal being located alongside wall (a), which is cooled internally by flowing water. The internal zone or core of the billet being cast is cooled at the inlet end of vertical or horizontal moulds, so the long molten core present in conventional continuous casting plants is eliminated.
