Title: Length measurement gauge with magnetic field on cursor - has scale markings made of of alternating, opposite polarity regions of permanent magnetisation of equal length
Inventor: HENTZSCHEL HANS-PETER DIPL PHY
IPC: G01D5/14
Filed: 1991-03-21
Abstract: The measurement gauge has a rod-shaped component (10) with a cursor which has a measurement tip perpedicular to it and magnetic markings extending along it. The cursor carries a sensor arrangement which interacts with the markings. It contains two magnetic fields, i.e. Hall sensors (14,16) at a defined longitudinal distance apart different from the scale of the markings. The magnetic markings are formed by a magnetic tape (12) extending along the rod with alternating oppositely magnetised, permanently magnetic regions of equal length. The sensor outputs are evaluated to produce a signal corresp. to the distance between the measurement tips. USE/ADVANTAGE - For length measurement, gauge is improved with high precision scale markings, resulting in accurate measurement substantially independent of temp..

Title: Manure processing - has separation of fluid and solid contents with drying chamber for solids and particle separation from fluid with recirculating air systems
IPC: C02F11/123
Filed: 1991-06-27
Abstract: To dry sludges, such as manure of different consistencies, by mechanical/thermal/ventilation processes, after the sludge has been split in the first stage by thermal and/or mechanical action into a solid portion with residual moisture and a filtrate with fine solid particles, the solid portion is passed through a chamber to be subjected to warm air. The extracted moisture is recirculated to be passed back for air drying and heating, while the dried solids are taken out of the chamber. The filtrate is finely distributed under pressure by spraying into a container through a lateral warm air stream for the filtrate droplets to be mixed intensively and generally converted to steam. The moist air stream is extracted from the container, together with any remaining fluid droplets and the fine solid particles for the particles to be sepd. on one side and, on the other side, the cleaned wet air stream is recirculated to be passed back to be dried and heated. ADVANTAGE - The system prepares sludges without affecting the environment, off site, in an assembly which is produced economically, and operates at low costs with energy saving to dispose of sludge.

Title: Polycrystalline oxidic high temp.-superconducting prodn. - from precursor powder by heating without melting undermicro gravitational conditions
Inventor: KRABBES GERNOT PROF DR
IPC: C04B35/45
Filed: 1991-08-19
Abstract: Prodn. of polycrystalline oxidic high temp.-superconductive materials (I) is carried out by thermal or chemical prepn . of a powdered precursor (II); then heating up to or briefly above the temp. lf partial incongruent melting of (II) in (an atmos. contg.) O2, without forming a homogeneous melt; holding at this temp.; and finally cooling until it solidifies completely. The novelty is that heat-up, dwell at temp. and solidification are carried out under microgravitational conditions. USE/ADVANTAGE - (I) are useful in the electrical industry and electronics, e.g. as superconductor. Partial melting is avoided. In an example, YBa2Cu3O(7-x) powder was prepd. from an intimate mixt. of 7.89 g BaCO3, 9.54 g CuO and 4.52 g Y2O3 by heating 24 h at 900 deg.C, crushing, re-mixing and repeating heating. This powder was crushed to an average particle size of 2 microns and moulded to a ring. The moulding was sealed in a quartz glass tube in the presence of 200 kPaO2. The tube was placed in a protective steel case. Under microgravitational conditions of 10 power(-2) go (go = the average acceleration of gravity at the surface of the earth), the moulding was heated 2 h at 980 deg.C, with heat-up to 900 deg.C at 0.1 K/min and cooling to 350 deg.C at 20 K/min, then treated at 350 deg.C for 20 h before cooling. The ring was superconductive below 90 K and had a critical current density of 10 power(5) A/cm2 at 77 K.
Patent DE-4127447-A1 (DE)
Inventor: HAUSER MICHAEL DIPL ING
IPC: B01F5/20
Filed: 1991-08-16
Abstract: The invention concerns a method of wetting power-station filter ash. Using prior art techniques, the ash is introduced, via a gravity-feed pipe, into a conical curtain of water produced by a ring nozzle supplied with water, where it is wetted and conveyed intermittently, in accordance with a fluid-flow paradox, into an elastic mxing line. In order to ensure comprehensive wetting of the ash particles, the ash is fluidized over the whole cross-section of the gravity-feed pipe and partly or completely rotated as it is introduced into the conical curtain of water formed by the jet, and conveyed along the elastic mixing line, which has a variable diameter. In order to achieve this, the gravity-feed pipe (4) has a diameter which will permit a high throughput and is connected to a feed device which fluidizes the ash. The nozzle outlet orifice (12) is designed with angles of 25 DEG /45 DEG  to 35 DEG /45 DEG  and the elastic conveyor line (15, 16) is formed by a short length of material loosely wound in several layers. At the open end of the line, the layers of material are disposed so that they can move relative to each other, and the scraper (23) has a flow output in contact with the stream of filter ash.

Title: Braided core of opt. fibre reinforced plastic - is formed with variable up and down speeds for strength of junction points of complex shapes
Inventor: AKIYAMA YASUO
IPC: D04C3/40
Filed: 1991-08-21
Abstract: In the formulation the upward and downward drawing speed is varied over a time span while the braiding is being developed. To form a tubular braided structure on a circular braider, the bobbin carriers are on an upper end of the cylindrical guide and a shaping core. the circular tubes can be assembled in a T-shape or a cross-shape. The braiding strands are moved up and down along the axes of the core tubes while the shaping core is rotated round the tube junction points to vary the braiding point and the braiding position in relation to the shaping core. During braiding, the raising and lowering of the shaping core is varied while braiding at the core tube junctions to control the braiding yarn density at the core junction or branch points. ADVANTAGE - The method allows a complex braided structure to be formed as a core with strong junction points between braided sections. (7pp Dwg.No.0/6)

Title: Interconnection of 2 aluminium@ metallisation layers in semiconductor - using reactive first layer and a transition layer between the aluminium layers in via-contacts
Inventor: HARADA SHIGERU
IPC: H01L23/522
Filed: 1991-08-27
Abstract: In semiconductor devices which have multiple, e.g. 2, Al interconnection layers (4,103), sepd. by an insulator layer (5) vias (6) are etched in the insulator layer to allow the 2 layers (4,103) to form a low resistance contact.

Ti, followed by a transition layer (102) also involving a refractory metal, pref. a refractory metal nitride, and then the second Al layer (103). The refractory metal layer, pref. 5-15 nm thick when deposited pref. forms an intermetallic layer (206) with the Al under it. The transition layer (102) is pref. 50-100 nm thick and has a resistivity of 250-400 micron-ohm.cm. USE/ADVANTAGE - Current processes using vias with aspect ratios greater than 1 show excessive via hole resistance.

Title: Bobbin brake - uses braking roller to bear against rotating surface of bobbin when detached from bobbin roller at open-end spinning winder station
Inventor: MAYER WALTER
IPC: B65H63/00
Filed: 1991-09-19
Abstract: To stop a bobbin, at an open-end spinner, the bobbin is detached from the bobbin roller, and a braking roller is applied to the bobbin surface to bring it to rest in a braking action. The bobbin detachment from the bobbin roller is independent of the braking roller movement. The braking roller is rotated generally to match the surface speed of the bobbin, before contact, and the roller is braked electrically. During braking, the bobbin is monitored, and the braking action is abandoned if the bobbin is not at rest within a given time span, and a fault signal is generated. During braking, the bobbin is monitored by scanning electrical values which are proportional to the surface speed, as a voltage. The bobbin can be doffed only when at rest. ADVANTAGE - The bobbin is brought to rest rapidly, without damage to the wound yarn.
