Patent DE-4028404-A1 (DE)
Title: Thermoelectric generator operating at low temp. -  having at least 2 chambers at different temps. has at least one sodium poly-sulphide cpd. in both chambers which are sepd. by solid electrolyte membrane
Inventor: KNOEDLER REINHARD DIPL PHYS DR
IPC: H01G9/21
Filed: 1990-09-07
Abstract: The thermoelectric generator, which has at least 2 chambers held at different temps. (3,4), features at least one Na-polysulphide cpd. in both chambers and a solid electrolyte membrane (5) sepg. the chambers which allows passage of alkali-ions. The first chamber (3) is held at pref. 400-500 deg.C. and the other (4) at 200-300 deg.C. A provision (2E) is made for excess Na-polysulphide to drain from the cooler chamber into the hot chamber. A condenser (6) condenses the vaporised S and leads it into the cool chamber (4). The hot chamber is pref. heated by a natural source, e.g. sunlight bundled by a parabolic mirror (7), or artificial process. USE/ADVANTAGE - The element can be operated at a lower temp. than current Na-based elements. There is no requirement to pump back a constituent or to adapt the return flow to the energy being drained from the element.

Title: Guided missile structure - has inflatable air-bag at rear end which reduces air resistance and increases range of missile
Inventor: BARTELS VOLKER DIPL ING
IPC: F42B10/44
Filed: 1991-01-24
Abstract: A guided missile (10) with a cropped rear end is fitted with an inflatable air bag (22) and a gas generator for inflating the bag. When the missile is in flight the air bag is inflated and occupies the region of stagnant flow which arises at the rear end of the missile. The device reduces the air resistance of the missile and increases the missile range. The air bag is initially folded into a small space at the rear end of the missile and so reduces the storage space required in comparison with missiles with rigid rear ends. USE/ADVANTAGE - Guided missile with increased range and reduced storage space.
Patent DE-4105400-A1 (DE)
Inventor: WIECZOREK LESZEK DR
IPC: G01N33/543
Filed: 1991-02-21
Abstract: The invention relates to solid support materials, e.g. microtitre plates, beads or microbeads, magnetic particles, films, filter papers and the like, which are coated with antibodies against recombinant fusion proteins, and to processes for the reproducible and defined coating of these surfaces with such recombinant fusion proteins. The recombinant fusion proteins contain a constant fusion partner and a variable antigen portion which constitutes the specificity of the test system. The abovementioned antibodies are directed against the constant fusion partner, that is to say the part of each fusion protein which is intrinsically not of analytical interest and pure.

Title: Cultivation process for ecological agriculture - comprises ploughing the soil, sowing and harvesting a first crop, applying natural salt soln. for weed control and sowing and harvesting a second crop
Inventor: SCHEFFER KONRAD PROF DR
IPC: A01B79/02
Filed: 1991-03-11
Abstract: A cultivation process for ecological agriculture without using synthetic herbicides comprises (a) ploughing or loosening the soil; (b) preparing the seed beds and sowing the first crop; (c) harvesting the first crop; (d) weed control using a salt soln. obtd. from minerals and consisting essentially of NaCl and/or KCl; (e) planting out or sowing the second crop in the unploughed soil; and (f) harvesting the second crop. In an alternative process, an intermediate crop, which freezes off in the winter is sown in step (b) and any non-frozen intermediate crops plants or weeds are pulled off as in (c). The rest of the steps are as given above. USE/ADVANTAGE - The process is ecologically sound and uses no synthetic herbicides. The substances used are natural and the amount of weeds is kept very low in an economical manner. Not ploughing the soil between the first and second crops is advantageous in that air and light, which would be let in on ploughing, would cause germination of weeds present in the soil

Patent DE-4136147-A1 (DE)
IPC: H04W56/00
Filed: 1991-11-02
Abstract: 2.1 The invention is based on a synchronisation method for a GSM mobile telephone. The synchronisation for a mobile telephone of this type must satisfy stringent requirements in terms of transmission reliability and accuracy and is intended to be implementable at minimum technical expense. 2.2 In the synchronisation method according to the invention, initial synchronisation, normal-operation synchronisation and final synchronisation take place during normal operation in the mobile telephone. The initial synchronisation is divided into rough frequency synchronisation, rough frame synchronisation and fine frequency synchronisation and fine frame synchronisation, whereas the normal-operation synchronisation comprises fine frame synchronisation with fine frequency synchronisation and data signal pre-processing, and the final synchronisation comprises rough frame synchronisation and fine frame synchronisation with fine frequency synchronisation. 3.

Patent DE-4211380-A1 (DE)
Inventor: ECKERT WERNER
IPC: E04B1/19
Filed: 1992-04-04
Abstract: A structural element (1, 1a to 1f) according to the invention is used for producing contours of prefabricated building units. The structural element essentially comprises two bar-shaped individual elements (2) arranged in parallel to each other. Said individual elements can be connected to each other on a longitudinal edge (8 or 9), by means of the axis (4a), with the aid of a folding hinge which is oriented with its axis parallel to the longitudinal axes of the individual elements. At the ends of the individual elements (2) there are located, at right angles to the folding hinge, connection hinges having the axes (7a) for connecting to neighbouring structural elements (1). In the connecting region of neighbouring structural elements, the hinge axes (4a, 7a) intersect outside the individual elements (2) in a common axis centre (11). By this type of connection and the construction of the structural element, a movable, cardan connection joint is formed, in which virtually any angular arrangements may be assigned to the structural elements connected to one another. <IMAGE>

Patent DE-4218899-A1 (DE)
Inventor: BROWN MALCOLM CHARLES
IPC: G01F23/292
Filed: 1992-06-09
Abstract: A flow measurement device for testing medical infusion devices comprises an upright tube 11 into which a flow to be measured is directed. The height of the liquid in the tube is sensed continuously throughout the entire length of the tube by a photo-electric strip, or by an array of closely spaced CCD sensors 14, responsive to a strip light 12. A logic arrangement 17 determines when the height of liquid in the tube changes, and triggers a calculation of rate of rise and flow rate. There can be two tubes with the flow switched between them, so that measurement can continue whilst one tube is emptying. Alternatively, the height of the liquid may be determined by measuring the capacitance between a central metal electrode and a conductive coating on the tube. <IMAGE>

Title: Static dissolver for tabletted treatment materials - particular water treatment chemicals operating at point of use
Inventor: SOECKNICK RALF DR
IPC: B01F1/00
Filed: 1992-10-08
Abstract: Production of an aqueous solution of a solid is carried out by placing above the bottom of a water-filled solution container and subjecting to the action of static water so that the solid dissolves. The novelty is that, for production of unsaturated dosing solutions for introduction into drinking water, utility, or process feed water at refrigeration, air-conditioning, or boiler installations, the level of the substance above the floor of the dissolving vessel, the volume of the solution tank and the amount of substance are chosen so that dissolution of the total amount of solid is not retarded by the concentrated solution accumulated at the bottom of the tank. Appts. is also claimed. USE/ADVANTAGE - Reduction of transported volumes of treatment substances and complete avoidance of transport water is effected by use of tabletted substances which are dissolved at point of use in a static dissolver unit. There is a 96% reduction in volume over transporting made-up solution;; 30-50% reduction over transporting loose powder; and 94% reduction in mass over transporting made-up solution; plus preparation of the dosing solution without the need for a mechanical agitator.
