Title: Arrangement for detecting the failure of resistive loads fed via current transformers
Inventor: STORM DITMAR DIPL ING
IPC: H05B37/03
Filed: 1981-01-24
Abstract: The application mainly deals with an arrangement for monitoring the failure of lamps in current-controlled series circuits of airfield lighting systems, the individual circuits of which are combined to form one lighting system. The lamps are fed via current transformers, the primary windings of which are connected in series in one circuit. The failure of the loads in the secondary circuit due to no-load operation, short-circuit or bypassing of primary windings by a low-resistance shunt leads to a change in the electrical data of the series circuit. The invention consists in that instrument transformers (5, 6) are placed in series and in parallel with the series circuit of the primary windings. On the secondary side, sensing elements (8, 10) are connected to the instrument transformers, the measurement values of which are conducted to switching and evaluating devices (17-22) with programmable switching thresholds. When these thresholds are exceeded, indicating signals are triggered. <IMAGE>

Title: Process for the preparation of immobilised glucose isomerase
Inventor: USHIRO SOICHIRO
IPC: C12N11/00
Filed: 1981-02-03
Abstract: An immobilised glucose isomerase is prepared by adding a non-ionic surfactant to a cultivated material. This cultivated material is obtained by cultivation of a microorganism which produces glucose isomerase. The cultivated material is then autolysed in order to dissolve the glucose isomerase without dissolving the polysaccharides present. A glucose isomerase solution which contains no or almost no polysaccharides is then separated off. The glucose isomerase solution is then contacted with a carrier able to adsorb the glucose isomerase.

Title: Device for, in particular, three-dimensional measurement and/or marking out and/or scanning of workpieces
Inventor: MASUR KLAUS
IPC: B23Q11/00
Filed: 1981-05-29
Abstract: Three-dimensional measurement device having a foot which can be displaced on a straightening plate and has a column at right angles to it and a compound-rest slide which can be displaced thereon and in which a transverse arm is mounted capable of displacement parallel to the straightening plate and transverse to the column. The measuring device has a compensation device, which compensates the influences of the transverse arm on the column by means of the foot and has a powered drive and a control or regulating element which is applied to said drive as a function of a parameter which determines the supporting force. The powered drive consists of a displacement actuator which on the foot displaces a counterweight, guided along a guide in a manner capable of being displaced parallel and in the opposite sense to the displacement of the transverse arm in the direction of projection. For the purpose of compensation, the displacement actuator presses the foot away from the guide surface and compensates deformations which are caused by an increase in length of projection of the transverse arm and can lead to falsification (corruption) of the measurement result.

Title: Toiletry compositions
Inventor: YAMAMOTO TAKESHI
IPC: A61K8/81
Filed: 1981-07-10
Abstract: The invention relates to toiletry compositions, e.g. lotions, creams, hair tonics and the like, which contain a perfume and are advantageously free of cutaneous irritation on use owing to the action of the perfume contained therein. The toiletry compositions contain the perfume in the form of a hydrated gel of a crosslinked hydrophilic polymer such as polyvinyl alcohol, which is impregnated with the perfume so that on contact with the human skin there are no direct adverse effects of the perfume. The perfume-impregnated hydrated gel of the crosslinked hydrophilic polymer is most favourably prepared by irradiating an aqueous solution containing the hydrophilic polymer and the perfume dissolved therein with high-energy ionising radiation such as  gamma  rays with radiation-induced crosslinking of the polymer molecules.

Title: Process for producing briquette binders
Inventor: ZELLERHOFF ROBERT DIPL CHEM DR
IPC: C10L5/14
Filed: 1981-09-11
Abstract: The process relates to the production of a low-smoke briquette binder from thermally treated mixtures of residual oils and plastic wastes. The predominantly aromatic residual oils of low sulphur content come from the processing of tar oils, from chemical processes based on mineral oil fractions, or from coal refining. They are blended in a ratio of 1 : 1 to 9 : 1 with polystyrene wastes and thermally treated for 1 to 6 hours at 300-400 DEG C and pressures of between 1 and 100 bar. After constituents boiling up to 420 DEG C have been distilled off, if appropriate after fluxing with high-boiling aromatic oils, the reaction pitch can be used as a binder for producing low-smoke briquettes having a good stability under fire conditions.

Patent DE-3200027-A1 (DE)
Title: Chimney with variable end cross-section
Inventor: EHRHARDT GERD DR ING
IPC: F23L13/00
Filed: 1982-01-02
Abstract: In known collecting chimneys, waste gases from a number of sources are guided upwards either in a collecting pipe or in separate pipes which are held by a support pipe which is not flowed through. The collecting pipe has the disadvantage that the exit speed of the waste gases then becomes too low if one or a number of waste gas sources stop. The separately guided pipes mostly have a relatively large pressure loss coefficient and are together with the support pipe considerably more expensive than the collecting pipe. These disadvantages are eliminated in the chimney (Fig. 1) according to the invention in that the waste gas pipes of the individual waste gas sources already end slightly above the chimney root in a collector and in that the collecting pipe has a variable end cross-section which is reduced in the event of stoppage of one or a number of waste gas sources to such an extent that the exit speed does not fall below a minimum permitted value. The exit cross-section is produced with lamellae of an iris diaphragm or with trapezoidal plates which are rotatable about horizontal axes, and can be adjusted automatically according to the speed required. <IMAGE>

Title: Road-surface finisher
IPC: E01C19/48
Filed: 1982-03-18
Abstract: The invention relates to a road-surface finisher according to Patent... (Patent Application P 3114049.1). This road-surface finisher can be used only to a qualified extent when there are large working widths or when there is a roof-shaped or V-shaped road-surface profile. The object is, therefore, to improve a road-surface finisher of this type, to the effect that it can also be used for a profiled road surface. This is achieved, according to the invention, in that the press strip is divided into at least two portions which are connected to one another by means of a joint, and in that the second screed following the press strip is also divided identically, so that the portions of the press strip and of the screed can shape and smooth the profile. It is important, at the same time, that the parting line between the portions in the screed should run obliquely relative to the direction of travel, so that, where appropriate, surface elevations originating from the parting line of the press strip are smoothed.
