Patent DE-3121031-A1 (DE)
Title: Device for regulating a heating system
Inventor: GELEWSKI HUBERT
IPC: G05D23/24
Filed: 1981-05-27
Abstract: A device for regulating (controlling) the temperature of a heating boiler is proposed, in the case of which regulation is carried out continuously. The regulating device comprises a PI regulator in parallel with which a comparator is connected. The PI regulator is switched off during the heating-up phase. On reaching a temperature which is close to the set required value, the comparator switches over and the PI regulator takes over the regulation. This avoids a transient behaviour, with the PI regulator overshooting, in conjunction with the control path. <IMAGE>

Patent DE-3131798-A1 (DE)
Title: Method and device for reprocessing graphite nuclear reactor fuel elements with mechanical dismantling
Inventor: THIELE DIETRICH DIPL CHEM DR
IPC: G21C19/36
Filed: 1981-08-12
Abstract: The mechanical dismantling of fuel elements is performed according to the invention with the aid of at least one high-pressure water jet. In this case, a distinction is made between the nuclear fuel and the graphite on the basis of the differing hardness, and the fuel particles are obtained in a largely undamaged state. It is particularly expedient to have for generating the jet a slotted nozzle which executes a pendulum motion. The fuel can preferably be supplied via an inclined channel which is adapted to the fuel element diameter and has a terminating grid adapted to the particle size. The water can be fed back in the circuit after separation of the suspended material. The suspended material is separated from the liquid by sedimentation or under centrifugal action, possibly under simultaneous density grading (classification). The graphite sludge finally obtained can be solidified directly with cement to form ultimate disposal blocks. The fuel is passed for chemical reprocessing.

Patent DE-3140010-A1 (DE)
Title: Wind power installation in a group system
Inventor: RASCHE ANTON ING GRAD
IPC: F03D1/00
Filed: 1981-10-08
Abstract: In the case of known wind power installations windmill sails were so arranged that the wind power wheels turned only in one direction. As a result the torsional forces were not adequately excluded; in addition the speed of rotation could not be controlled. These problems are resolved according to the invention in that a plurality of wind wheels in pairs rotate in opposing directions, which as a result reduce or cancel out the torsional forces. A centrifugal governor is fitted for controlling the speed of rotation. The centrifugal governor (9) transmits its action to the torsion bar (26); this produces an axial movement of the contact plate (21) and the connecting rods (22). The rods are connected by deflection to the stay bolts (25) of the blades (17) so that the blades can be turned about the axis line (24) and the narrow side of the blades thereby set against the direction of the wind. The wind power installation can be used to produce energy in widely varying contexts, both as a small power installation and as a large power installation. <IMAGE>

Title: Javelin training equipment for imitating javelin throwing in indoor sports halls with photoelectronic measuring and display device to assess the quality of a throw
Inventor: SPRENKER ROLF R
IPC: A63B21/06
Filed: 1982-02-15
Abstract: To train technique in throwing from a standing position in javelin throwing in indoor sports halls, a throwing sleeve which corresponds in appearance to the central part of a competition javelin and is constructed in different weights is moved on an iron tube, clamped in two bearings, as a guide. To assess the quality of a throw, the time and the speed of the sleeve are measured shortly after leaving the hand with the aid of two light barriers which are placed with short spacing in the slide path of the throwing sleeve. The time or the speed value is converted to a "distance value" via a programmable computer with the aid of the formula for the throw curve or a formula which has yet to be developed for the aerodynamic flight of the javelin.

Patent DE-3209810-A1 (DE)
Inventor: POST HANS DIPL PHYS DR
IPC: A61B5/05
Filed: 1982-03-18
Abstract: For recording the nuclear magnetic resonance in selected areas of a body for the purpose of representing body cross-sections in the form of images (NMR tomography), wherein the nuclear spins of a selected type present in the area of one plane of the body are subjected to a superimposed gradient field varying in the selected cross-sectional plane, and selectively excited, the excitation of the nuclear spins is effected by application of a pulse sequence which induces the nuclear spins to supply at one stage a number of chronologically successive induction signals. The induction signals corresponding to each other in chronolical sequence are then processed to obtain separate sets of image signals so that by one single measurement a sequence of cross-sectional images is obtained which differ from each other by the intensity of the excited nuclear spins which varies according to the relaxation times T1 or T2. The fact that all images have been obtained by one and the same measurement provides the possibility to determine the relaxation times T1 and/or T2 related to the individual image points and to use them on the one hand for purposes of selective image representation and, on the other hand, for improving the image quality.

Title: Underframe of a displaceable vehicle seat
Inventor: BURGER KLAUS
IPC: B60N2/02
Filed: 1982-06-15
Abstract: With the underframe, both the leg room and the height of the seat can be adjusted. It is improved with respect to functional reliability, loadability, lightweight design and economical production to equal degrees, by virtue of the fact that the two lower slide rails and the two upper slide rails are produced completely from extruded material with the same profile and with a profile wall which protrudes upwards in the position of use of the slide rails, the profile wall is partially removed in the two lower slide rails in a manner which produces space for the upper guide rail in the front area of the vehicle seat and is connected over a large area to the cross element and is designed so as to be capable of being connected at the two upper guide rails over a large area to the bearing structure of the seat upholstery and the cross element is composed of a hollow extruded profile or another distortion-resistant lightweight member. One kind of extrusion material is sufficient for all four slide rails although the profile wall of the extrusion material on the lower slide rails impedes one end section of the upper guide rails and, in addition, the right-hand and left-hand slide rails are to be differentiated.

Title: Arrangement for limiting the noise emission of the internal combustion engine of a motor vehicle
Inventor: KURZ WALTER DR
IPC: F02D41/14
Filed: 1983-01-28
Abstract: In order to limit the noise emission of an internal combustion engine of a motor vehicle, the engine output is so controlled that the temporary variation of the engine speed n as a function of the instantaneous engine speed n is always less than a predetermined speed change-speed characteristic (47) stored for example in a read-only memory. The characteristic (47) remains constant within a lower speed range and then in an upper speed range up to an upper limit speed (nb1) decreases to the speed change value zero. Different speed change-speed characteristic curves are assigned to the individual gears of a motor vehicle manual shift transmission, the maximum values of the speed changes decreasing at higher gears and the upper limit speeds increasing. <IMAGE>
