Title: Acid-hydrolysing cellulose contg. material to sugar - by first reducing to fibres then heating
Inventor: KNAUTH HANS DIPL ING
IPC: C13K1/02
Filed: 1978-06-22
Abstract: Process for continuous hydrolysis of cellulose-contg. material with dil. acid at high temp. comprises sepg. the material into fibres at the beginning of hydrolysis, then subjecting the suspension to additional heat treatment. The catalyst may be introduced by pre-impregnation or during sepn. into fibres, and may be used together with a solvent for lignin. After hydrolysis, the solvent may be expelled from the hydrolysate and reused. Used for recovering sugars from cellulosic raw materials or wastes. Any material regardless of its morphological structure can be used and max. sugar yield is obtd. Complete and uniform distribution of catalyst is achieved; the liquor ratio is kept to a min., and the sugar prod. is rapidly withdrawn from the reaction zone, so repolymerisation and caramelisation are reduced.

Title: Four terminal fail safe resistor - has conductive tracks which open circuit when subjected to abnormal thermal or mechanical loading
Inventor: MONTANARI PIERO
IPC: H01C7/00
Filed: 1978-08-04
Abstract: Each pair of two pairs of terminals is connected together by a conducting strip of a metallic material deposited on a fragile support block. The strips are shaped in an interwoven pattern, with an intervening space, such that the support block will not break along the space pattern. The strips are connected by a resistance material deposited along the space pattern and overlapping the adjoining strips. The four terminals are connected into a circuit so that the resistance material forms part of a resistor network which if interrupted causes that circuit to assume a safe condition. Any rupture of the resistance material and/or the support block due to thermal differences or mechanical force interrupts the continuity of one or both connector strips to create a safe failure condition.

Title: Fabric-guide device for sewing machines - having inclined airjets to hold and assist transport of the fabric
Inventor: NORZ WOLFGANG
IPC: D05B35/10
Filed: 1978-09-11
Abstract: An edge-guiding device for material being fed through a sewing machine, the material being held in position by jets of compressed air, is described. The air-jets are so inclined to the plane of the material as to produce a pushing action to reinforce the turning movement produced by the feed mechanism of the sewing machine. Inclined jets facilitate the edging of material with tightly-curved edges. The guide comprises upper, middle and lower plates joined along one side by an edge-rail. The jet orifices drilled into the upper and lower plates are fed by compressed air lines and are inclined against the direction of movement of the material, and also towards the edge-rail, tending to push the material in a direction essentially tangential to the rotary movement produced by the material feed mechanism.

Title: Spinning fibre feed control - uses fibre weight measurements to adjust conveyor speed for constant supply at each station
Inventor: GUILLOT FRANZ E
IPC: D01G23/06
Filed: 1978-10-20
Abstract: To control the feed of fibres to spinning machines, the weight of the fibre material on the conveyor is measured continuously or intermittently. This weight reading, together with the conveyor speed, are compared with a norm. The speed of the conveyor is adjusted to correct any deviation from the pre-set control value to give a fibre weight dosing to the spinning stations within time units at a constant rate for the successive machines. The process compensates for the irregular distribution of the silver on the conveyor, partic. when working with synthetic fibres, so that each spinning station is evenly fed.

Title: Printing colour quality monitor - has three-colour scanner head with output to coder multiplexer and data comparison store
Inventor: GAST UWE DR
IPC: H04N1/62
Filed: 1978-12-12
Abstract: The colour quality and control monitor produces a signal for each of the three colours, yellow, magenta and cyan, so that the printed quality of the output product, textile, packing material etc. may be maintained. The monitor head splits the monitored colour into three components, red/cyan, green/magrenta, blue/yellow so that each has a separate path from the colour scanning head through the signal multiplexing and switching units and into the monitor control which provides output to the indicator display unit. The colour comparator stage produces a 4 bit word to describe each colour saturation level. The 4 bit codes for each colour are fed through a coder into the multiplexer for comparison with stored digital signals used for the measuring and monitoring process. The variations are centred on the multiplexing and store operating alternative for this equipment which is primarily intended for control and monitor of a printing process.

Title: Circuit for measuring value of variable resistor - eliminates effect of lead resistance and controls offset and range
Inventor: DESTREE KARL HEINRICH ING GRAD
IPC: G01R15/08
Filed: 1979-02-05
Abstract: A variable resistance (R) is measured by supplying it from a constant current source (9) and examinin the potential across it with a buffer-amplifier (5). By using a second pair of leads to the resistor the potential measured by the amplifier is independent of the lead resistances. A reference (RO) is also supplied by a constant current source, isolated from the first source byt synchronised to it. This resistor is conected in series with the variable resistance in order to offset the measurement range. This reference resistor (RO) together with an amplifier gain seting resistor (RG) can be packaged in a separate module to permit convenient range changing.

Title: Telephone exchange connecting line condition detector circuit - uses transient EMF induced in tertiary winding on repeating coil to operate opto-coupler
Inventor: DIRR JOSEF ING GRAD
IPC: H04Q1/30
Filed: 1979-02-06
Abstract: Two subscribers on an internal exchange are connected together via selector contacts, and to the battery via a relay and a repeating coil. When one subscriber hangs up, the current drawn from the battery falls, but not sufficiently to release the relay. A tertiary winding on the repeating coil has sufficient transient e.m.f. induced in it to operate on optocoupler. This triggers a bistable which energised a time delay relay with a time delay of approx. 100mS. After the time delay, a further relay is energised, one contact of which releases the two subscribers while another resets the bistable. The subscriber who hung up is now free while the other is still engaged.

Title: Tubular heater with U=shaped resistance heating filament - has ceramic spacer in metal tube which is compressed to close all internal spaces
Inventor: SCHWARZKOPF EUGEN
IPC: H05B3/48
Filed: 1979-03-01
Abstract: The heater has its resistance heating wire (3) wound around a flexible insulating core (2) which is then bent into a U-shaped and inserted into a ceramic spacer (7) inside a metal tube (10). The spacer is cylindrical and has appropriate longitudinal holes (5, 6) to accommodate the heating wire. The junctions between resistance wire ends and connection leads are located inside the holes in the ceramic. The space between the end of the ceramic spacer and the closed end of the metal tube is filled with granulated or powdered insulating material. The metal tube is reduced in dia. over its entire length in order to compress the insulating material inside it thereby closing the holes around the resistance wire and leads. The tube is compressed such that its final dia. is roughly 3/4 of its initial dia. The heater's break over or breakdown voltage is thereby increased.

Patent DE-2922639-A1 (DE)
Title: Strength increasing process for gear-teeth - uses roller to provide plastic deformation of metal at tooth root
Inventor: SCHURAVLEV GERMAN ALEKSANDROVI
IPC: B23P9/02
Filed: 1979-06-02
Abstract: The strength of gear teeth can be increased by plastic deformation of the regions which are critical from consideration of the bending moment. A roller (20) with a rim of wedge-shaped cross-section is pressed into the space between two adjacent teeth (5, 6). The metal at the root of the tooth is subjected to a high compressive stress which causes plastic deformation so that there is a residual compressive stress after the roller is removed. This residual stress reduces the maximum tensile stress at the roots when the teeth are subjected to a bending moment.
Patent DE-2932494-A1 (DE)
Title: Dairy heat exchanger - with hot milk side stream by=passing heat exchanger section for mixing with chilled milk
IPC: A23C19/05
Filed: 1979-08-10
Abstract: In dairies, one part of the milk has to be pasteurised by heating and deep freezing, and another part is heated and just cooled to the cheese making temp. The heat of the hot milk is recovered by passing it in a counterflow to the cold milk. A side stream of the hot milk bypasses the reflux in a heat exchanger and is mixed with the cool milk. This saves any additional energy input for producing milk of 28-34 degrees C as required for cheese making.
Patent DE-2936004-A1 (DE)
Title: Rotary drive with alternate cam drives - has coaxial gears sequentially driven by half toothed cams

Title: Mfg. compost by decomposing organic waste in mechanised silo - which conveyor and compacts with min. wear of moving parts
IPC: C05F17/02
Filed: 1979-09-15
Abstract: Process and mechanised silo is for decomposing and/or drying organic waste material. The silo is of the type which is supplied with waste in bulk. The waste is advanced through a silo reaction chamber for aeration, deaeration heating, etc., being retained for a period necessary for decomposition, generally about 10 days in all. The reaction chamber is now formed as a tunnel. Equal batches of waste are introduced at regular intervals at one end of the tunnel. Each batch in turn is advanced further into the tunnel to make room for the next batch. The newly introduced batch pushes preceding batches as it advanced, the compacted, unified mass sliding on its base along the floor of the tunnel. Equal batches of processed compost are periodically discharged at the outlet end of the tunnel. Two or more tunnels can be superimposed, a gravity transfer of periodic batches taking place from the upper to the lower tunnel. Used for drying and/or decomposition of organic waste partic. for the mfr. of compost. The cycle can be arranged to ensure complete decomposition. The necessary conveying and compacting motions are effected with min. mechanical effort. Wear on moving parts is reduced to a min. Optimum use is made of oxygen.
