Title: Hydraulic rudder control circuit - has non return valves in lines from multiway valve to working chambers, return flow controlled by opposite-line pressure
Inventor: BITZAN ROBERT
IPC: B63H25/22
Filed: 1979-04-05
Abstract: The rudder-control circuit is basically conventional with a multiway valve directing flow to/from one or more rudder operating cylinders and braking unit for keeping the system permanently pressurised. The braking unit (20, 21) fits between the multiway valve (12) and each of the operating cylinders (8, 9). Each unmt contains a mitre-seat non-return valve controlling flow to the cylinder and a throttle valve, operated by pressure from the line to the other unit, controlling return flow. Bypassing each of the braking units is a pressure-limiting valve (22, 23).

Title: Ion exchange resin regeneration - by removing cation-anion boundary layer from transfer line during regeneration
Inventor: EMMET JAMES RATCLIFFE
IPC: B01J49/18
Filed: 1979-05-28
Abstract: Ion exchange material which has been spent in the production of high-purity water is regenerated by extracting first the cation exchanger and then the cation/anion boundary surface layer and by terminating the transfer when the latter is still in the transfer line, as described in the Parent Patent No. 2823070. This boundary layer is removed from the line after the ion exchanger tank outlet has been isolated from its inlet, but before the ion exchange regeneration is completed. Experience has shown that this improves the regeneration of the ion exchange material.

Title: Plastic waste pyrolysis - by counterflow in inclined cylinder externally heated to high discharge temp.
Inventor: HOELL RUPERT
IPC: C10G1/02
Filed: 1979-06-22
Abstract: The pyrolysis of plastic waste and of refuse with a hydrocarbon content such as discarded tyres and cables, spent oil etc. takes place in a stationary or rotary steeply inclined cylinder. Tbe pyrolysis gases are extracted in counterflow to the material flow. Tbe reactor is externally heated in the lower part and is cooled in the upper part by tbe air to be used for combustion. A marked temp. gradient is maintained between the discharge of the residue (at 800 deg.C) and the pyrolysis gas exit. This improves the yield of low-boiling pyrolysis prod. at the expense of the higher-boiling prods. for which there is little application. Aromatic prods. are obtd. without undue increase in the amt. of lean gas. The energy losses have been reduced.

Title: Radio direction finder with two channels - compares phase of summed offset voltages with phase of reference voltage
Inventor: HISSEN HELMUT DR ING
IPC: G01S3/14
Filed: 1979-09-13
Abstract: The direction finder uses two voltages dependant on the reception direction of the electromagnetic waves and as auxiliary voltage independent of the latter. The initial two voltages are phase-shifted by 90 degrees relative to one another and summed, to obtain a compound voltage, compared in phase with the auxiliary voltage to determine the reception direction. The two initial voltages are supplied via respective channels (X,Y), one incorporating a phase-shifter (1) and both coupled to a summing circuit (2), connected to one input of a phase detector (3). This receives the auxiliary voltage at its other input and provides a phase difference signal from which the azimuth angle (4) of the received waves can be directly obtd. This phase difference is also used to adjust a phase-shifter (6) receiving the auxiliary voltage its output used to compensate channel noise.

More specifically, TiO2 is prepd. by (a) preheating an oxidising gas stream to 800-1600 (pref. 900-1300 degrees C)., (b) preheating a TiCl4-contg. strea to 250-500 degrees C., (c) adding 1-75 (pref. 10-40) esp. 15-35 % TiCl4 to the oxidising gas stream, (d) allowing the oxidn. reaction to occur, (e) adding to the reaction stream, in >=1 feed zones, 99-25, esp. 65-85% TiCl4 to be oxidised, (f) allowing the oxidn. reaction to occur and (g) cooling and collecting prod. TiO2. The oxidising gas stream is O2, air or O2-enriched air, opt. contg. water vapour, Cl2, alkali metal halide and/or alkaline earth metal halide and/or alkaline earth metal halide. The TiCl4 opt. contains a halide of Al, Si or P and the reaction is effected in the presence of the additional halide. The TiO2 prod. is rutile or anatase form, and is useful as a pigment. The process uses less energy to initiate and maintain the reaction than single step processes, as reaction heat is used, and provides a lower, more uniform temp profile during the reaction, avoiding excessive temps.

Title: Quarter wave length coaxial type resonator - provides screw adjustment of centre electrode and screw locking collar
Inventor: PELZ DIETER ING GRAD
IPC: H01P7/04
Filed: 1980-01-15
Abstract: The resonator comprises an outer hollow cylinder with a blank end or base, and a coaxial central round rod. The rod and hollow cylinder base form a short circuit. To allow fine tuning without circuit interruption the rod is screwed into the base. An insert with a conical end has external and internal threads. The base is drilled and tapped, the hole ending in a cone whose angle matches that of the insert. The centre electrode has an external thread and slotted head at one end. The components are all screwed together. With the insert tight the electrode is locked. Slits in the insert at the conical end allow it to grip the electrode. To make an adjustment the insert is slackened sufficiently to allow the electrode to be turned in its thread to give axial displacement. The max. displacement can approach the length of the cylindrical part of the insert.

Title: Wheat gluten thermal treatment - in cylinders with high-speed horizontal cutter shafts before ascension tube drying
Inventor: FEMERS KURT
IPC: B01F7/00
Filed: 1980-03-25
Abstract: The thermal treatment of gum-like viscous material such as wheat gluten, produced in the manufacture of wheat starch, was described in the Parent Patent No. 2812122. The pretreatment chamber with the high-speed shaft carrying radial cutter blades is now arranged horizontally. The ascension tube dryer receives the charge from this chamber at its bottom elbow. The chamber is preferably subdivided into two chambers with independently driven cutter shafts.

Title: Highly diastatic kiln-dried malt, esp. wheat malt prepn. - by wet and dry steeping with germination-stimulator addn.
IPC: C12G3/00
Filed: 1980-07-25
Abstract: New highly diastatic kiln-dried malt has diastatic energy at least 580 deg. WK (Windisch-Kolbach). A highly diastatic malt is prepd. by malting grains using a wet-dry steeping tank. The grains are first steeped, in the thinnest possible layer, in flat steeping tanks at 10-14 (12) deg.C. Steeping time comprises 1/4 wet- and 3/4 dry-steeping. The grains are strongly aerated while wet and strongly sucked off when dry. After steeping, the degree of steeping is 35-42 (38)% and the temp. is allowed to rise to 16-20(18) deg.C in 3 days, followed by cooling to 8-12 (10) deg.C in 4 days. Germination-stimulators are added during this time, and, towards the end of this period, also water to water-content 45-51 (48)%. The prod. is kept 4 days at this temp., at a constant water content of 45-51 (48)%, and then kiln-dried with a high air excess. The prod. is used as an animal feedstuff additive, e.g. for pigs and calves, and in starch saccharification, esp. for distilleries. Malt yields are good, reaching 65-70% in malting wheat. The high diastase content increases malt digestibility when used as feed additive.

Title: Optical testing by intensity scanning in longitudinal lines - using line-scan CCD camera supplying memory forming characteristic data and evaluation circuit
Inventor: GIEBEL HAYO DR ING DR
IPC: G01N21/952
Filed: 1980-08-08
Abstract: An arrangement for testing rod-shaped objects moving perpn perpendicularly to their longitudinal direction involves detecting and evaluating the light directed from a source (4,5) onto the object (12). They enable the lengths and dia. of objects to be measured as well as the position and shape of markings, esp. those to be found on cigarettes. The intensity distribution along a linear surface region lying in the longitudinal direction of the object is measured quantitatively from the light reflected from it. Data from successively scanned lines of the surface are placed in a memory and subsequently processed into characteristic object information. The light reflected is received by a row of photoelectric transducers connected to an evaluating circuit. The transducers may be made into a linescan camera (1) using charge-coupled elements (2).
