Title: Process for the concentration of fibrous material
IPC: C03B37/10
Filed: 1980-01-31
Granted: 1983-03-30
Abstract: Process for the concentration of fibrous material in a mixture thereof with non-fibrous material, by causing an aqueous suspension of said mixture to flow upwardly to bring about settling out of material of reduced fibre content and formation of a fibre-enriched fraction above it, which is then separated. In the process, the upward flow is made substantially non-turbulent, and is carried out with gas bubbles passing upwardly through the suspension, to increase the efficiency of separation of fibrous from non-fibrous material. The process is specially applicable to the concentration of fibres in the fibrous product (mineral wools) formed by disintegrating silicate and like mineral melts, which commonly contain a relativnly high proportion of granular material ('shot').

Title: Display arrangements
Inventor: NIXON R D
IPC: G09F9/30
Filed: 1981-11-26
Granted: 1985-08-21
Abstract: A display arrangement consists of one or more elongate display devices, each of which has a number of separately energizable display areas positioned along its length. When energized, each display area is seen as a bright patch of light. As it is very difficult to arrange that the display areas extend right to the extreme ends of the device, optical deflection means are positioned in front of the display areas to magnify the size of each so that the total display area extends over the whole length of the elongate display device. The optical deflection means is arranged so that each bright patch is of substantially the same size. The invention enables a large number of similar elongate display devices to be placed end to end while avoiding the appearance of periodic dark patches at the ends of adjacent devices.

Title: Gas-cylinder valve
Inventor: NITTA JIRO
IPC: F17C13/04
Filed: 1989-01-12
Granted: 1992-03-11
Abstract: In a gas-cylinder valve adapted to be mounted onto a gas cylinder for use there are provided a gas supply valve chamber and a protection valve chamber in sequence between a gas inlet and a gas outlet within a valve box of the gas-cylinder valve.

Granted: 1986-06-18
Abstract: The head includes a number of electromagnetic structures each one coupled to actuate a respective printing needle. Each structure has a supporting disc to which electromagnets are secured. The magnet forms its magnetic core having sheets on which a locating appendix is provided to fit in a respective aperture in the disc. A coil is wound on each core. A movable armature closes the magnetic circuit, an extension arm acting as a lever arm for the actuation of the needle. The arm is inserted between two posts disposed internally of an armature retainer. The rest position of the lever arm is provided by internal bumps of a resilient ring. Each bump is adjusted in position by an adjusting screw housed in a threaded seat in a rubber ring supported by a cap, on one side of which the ring is vulcanised. Any tendency of the screws to come unscrewed due to vibrations of the head is resisted by the frictional engagement with the rubber ring.

Abstract: In tyre factories and warehouses stocking a large variety of tyre sizes it is necessary to know how many tyres of different sizes, materials and type numbers have been made or are in stock. This is often done manually, taking a long time and being subject to human error. The apparatus performs this process automatically. a source of irradiation lights up the tyre markings and the tyre can be automatically moved to align the markings with the optical system. a camera tube receives the image via two prisms, mirrors and a lens system. this information is transferred to a memory and registration apparatus which prepares the required records. The computing system can be as known.

Title: Circular indexing table for machine tools - has remote controlled jacks round edge to adjust level of table
IPC: B23Q/
Filed: 1974-12-12
Granted: 1980-06-30
Abstract: The rams adjust the level of the table to maintain it horizontal, the adjustment being necessary because of the position of heavy leads on the table. The rams are attached to the table support, and run on rollers on a surrounding rail. The movement of the rams is caused by remotely controlled gear motors, a shaft engaging with a helical gear into which is screwed the shaft of a ram. A lever pivots about an axis and has its spherical end engaged in a slot in the ram. Movement of the ram is amplified by the ratio of the two, and electrical contacts limit the movement of the ram. The ram forces can act against sets of blocks attached to the table or to circular rings round the edge of the table.

Title: Diagnostic aid for kidney function - on the basis of polyfructosans from monocotyledons plants - water soluble, non-tox
Inventor: MUHLBOCK S

Filed: 1971-12-09
Granted: 1981-10-10
Abstract: Easily water-soluble polyfructosans from the storage organs of monocotyledon plants esp. from those of the family Liliaceus and Gramineus are used as diagnostic aid for kidney function. The pref. plants used are Urginea maritima, yielding Sinistrin, and Allium sativum. The roughly macerated plants are extracted with lower alcohol or acetone contg. 80-40% water. The extract is adjusted to pH 9, filtered and concd. and solvent is added so that no ppte. is formed. Acidification with HCl to pH 1-3 and addn. of excess solvent gives pptn. of polyfructosan (I) which is further purified. (I) are very water-soluble which compares favourably with known polyfructosan Inulin which is not very soluble in cold water. (I) are non-toxic and, upon parenteral administration, are not metabolised or changed in the body but excreted by the kidney. In an example, 100 kg. commercial sea onions are extracted as described using 30% aq. methanol as solvent, to yield 31.5 kg. of pure Sinistrin.
