Title: Method for generating energy by nuclear fusion
Inventor: WILDENHAYN REGINALD DIPL CHEM
Filed: 1981-04-07
Abstract: For the purpose of the nuclear fusion of light elements such as deuterium and tritium, the aim is to effect the mutual electrostatic repulsion not by thermal energy at extremely high temperatures but by acceleration in electric fields. To this end, magnetically focussed ions such as deuterium and tritium are accelerated separately by electric fields and fired at one another in an evacuated reaction tube in such a way that they collide at at least 10 KeV. One or more such reaction tubes are located in a pressurised water reactor and in addition are surrounded for the purpose of breeding tritium by tubular jackets which contain a suitable Li compound. The heat released in the reaction tubes and tubular jackets is dissipated to the surrounding water and then serves in a known way to generate steam.

Patent DE-3134524-A1 (DE)
Title: Ski climbing aid
Inventor: HEPPENHEIMER HERMANN
IPC: A63C7/00
Filed: 1981-09-01
Abstract: The invention relates to a pivotable ski climbing aid which in the rest position is arranged parallel to the ski and in the operating position is rotated through 90 DEG . When the ski climbing aid is moved into the operating position, brake elements preventing the skis from slipping back pivot via torsion springs preferably into a 79 DEG position against a stop. At the same time, a spring-loaded bolt or strip is released below the brake elements preventing the skis from slipping back, which bolt or strip is placed in a recess in the receiver screwed to the ski and thus retains the ski climbing aid in the operating position. When the brake elements preventing the skis from slipping back are pivoted back into the starting position, the bolt or strip is likewise pressed back into the starting position counter to the spring and releases the retention. In the rest position, secure fixing is ensured by a form spring which engages in a recess in the receiver. Due to the fact that all the function elements are accommodated in a flat closed housing, the ski climbing aid is distinguished compared to known designs by the fact that there is no risk of injury whatsoever and the impedance is low.
Patent DE-3140777-A1 (DE)
Title: Compound frame system of aluminium/wood/aluminium for windows, doors and façades
Inventor: BORKHOFF HERBERT
IPC: E06B3/263
Filed: 1981-10-14
Abstract: Compound and compact profiles having inner and outer aluminium profiles with a wooden core in 5-7 mm bar lengths glued in a two-way manner and so as to be resistant to boiling water, for the economic manufacture of insulated aluminium windows and doors, having very good heat-insulating and sound-proofing properties. Connection of the inner and outer aluminium profiles, screwed invisibly and non-displaceably in the frame groove, with great bending resistance. The wing frames have no glass strips and are glazed by unscrewing the outer profiles. For rational manufacture, compound wing profiles and compound outer frame profiles and the central sealing means are connected as a compact profile unit and are cut to size jointly in one operation. The wooden core can be manufactured for variable frame thicknesses and glass groove widths in various dimensions without changing the aluminium profiles. Only one glass strip dimension is therefore required for fixed glazings. The linearly inserted central sealing means can no longer shrink and does not need to be bonded at the corners. Transoms and additional profiles can be manufactured in any desired constructional widths in a fully insulated manner by groove cuttings and transverse screw connections. <IMAGE>

Filed: 1981-10-30
Abstract: The invention relates to an extremely efficient automatic vehicle transmission with infinitely variable transmission ratio between input speed and output speed. The transmission comprises a torque converter with a first impeller wheel connected to the input shaft. A second impeller wheel is operationally coupled to a sun gear and receives operating fluid from the first impeller wheel. A turbine receives operating fluid from the second impeller wheel and in turn drives an internal gear. A reaction element operationally coupled to a one-way brake is arranged between the outlet end of the turbine blades and the inlet ends of the blades of the first impeller wheel. At least one pair, preferably three pairs of intermeshing pinions are arranged between the sun gear and the internal gear, one pinion meshing with the sun gear, whilst the other pinion engages with the internal gear. The rotational movement of these pinions is transmitted by way of a carrier arrangement to the output shaft of the transmission arrangement.
Patent DE-3145374-A1 (DE)
Title: Process and device for combating ground targets by means of missiles
Inventor: KALTSCHMIDT HORST DR ING
IPC: F41G7/22
Filed: 1981-11-14
Abstract: The invention is concerned with a process for combating ground targets, especially tanks, by means of missiles (1). The trajectory of the missile (1) is subdivided into three phases, namely the initial, middle and final phases. In the initial phase, the missile (1) flies at ground level, in the middle phase in an ascending trajectory which is laterally offset from the target and which allows it to scan the terrain for targets in the SAR mode, and in the final phase in target approach from above towards the target. The initial and middle phases are flown in a programmed manner. In the middle phase, the coordinates of multiple targets are determined by means of a radar homing head, and the approach course for the final phase is calculated and programmed by target selection. So that the antenna (6) can be kept small in view of the peculiarities of the construction of slender missiles, a synthetic aperture is used. Reference Doppler histories (X'11, X'12, X'13) are filed in binary form in a memory (8). The Doppler histories (X11, X12, X13) of the reflecting spots, which are received by the antenna (6), are transmitted, via switches (9a, 9b, 9c) operated via the memory (8) containing the reference Doppler histories, to a low pass (10a, 10b, 10c) and a threshold detector (11a, 11b, 11c) located behind it. A very simple processing of the signals obtained is thus achieved. <IMAGE>

Title: Process for removing dust from different gas streams
Inventor: STEINBACHER KARL
IPC: B03C3/014
Filed: 1982-03-26
Abstract: To remove dust from a plurality of gas streams differing with respect to flow rate, composition, temperature, dust charge etc., a process is proposed in which each individual gas stream is conditioned separately, then fed to a gas mixing chamber and finally collectively purified in an electrostatic precipitator. Such a process is suitable in particular for the gas streams produced in a steel works from so-called secondary dust sources. In this case, gas streams from 25,000 to 2 million m<3>/h are produced in a temperature range from 50 to 750 DEG C. In order to be able to wholly or substantially avoid conditioning at low gas temperatures, which is only possible with expensive steam, it is proposed to humidify the gas streams at relatively high initial temperature more intensively than is required for the electrostatic purification, in order to introduce into the gas mixing chamber by this means the amount of moisture required for the gas streams of low temperature and to be able to feed to the electrostatic precipitator a correctly conditioned overall gas stream.

Title: Drying section of a paper machine
Inventor: SCHIEL CHRISTIAN
IPC: D21F5/04
Filed: 1982-05-28
Abstract: In the drying section of a paper machine, the paper web (10) to be dried runs, together with an endless air-permeable supporting band (17), over drying cylinders (11 to 15) in a meander-like manner. An air-guide box (20) is provided on the side of the supporting band in the running path from an upper cylinder (11) to a lower cylinder (12). Between a side wall of this box (plate 21) and the supporting band (17) remains a narrow air gap, in which the supporting band generates an air flow. Furthermore, air breakaway strips (22 and 23) are provided on the box (20). To avoid the need to suck off air from the entry gusset (9) on the lower cylinder (12), the following is provided: the box (20) has, in the region of the entry gusset (9), large-area air-inlet orifices (25) which are in unthrottled communication with the air gap at the plate (21). Moreover, large-area air-outlet orifices (26) are provided in the upper region of the box (20). <IMAGE>

Title: Ecologically friendly deep-sea mining
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: E02F7/00
Filed: 1982-07-01
Abstract: The foldable flat freezing grab and the rolling cylinder freezing grab for the raising of ore nodules formed on the sea bed are discussed with reference to the main application and the first supplementary application. The folding grab can be expected to exhibit a low flow resistance and intensive cutting of the nodule zone upon lowering to the sea bed and mutual protection from mud emission and dropping of useful load when raised above water with folding of the useful-load pans. Upon arrival above water and without removal of the unit from the rope karabiner, the two useful loads are discharged with an automatic multiple-ram arrangement, and the grab device is immediately ready again for the next cycle. The cylindrical rolling grab is pulled along by the cable of the ship by brief motion of the ship and, rolling on the sea bed in frictional contact, obtains its cutting and loading rolling movement. Its advantage over all flat freezing grabs is a much greater loading and transporting capacity while maintaining the freezing coupling of the useful load to the grab, because the nodules take up a great many nodule layers during multiple circulation of the grab, the sand being displaced as ballast from the nodules.
