Title: Side reflector for gas cooled pebble bed reactor - has seals at joints between columns of blocks to prevent gas flow into core
Inventor: ELTER CLAUS DR
IPC: G21C1/07
Filed: 1980-10-29
Abstract: A side reflector for a nuclear reactor, esp. gas-cooled, pebble-bed reactor, is composed of a number of vertical columns of graphite blocks; these surround a generally cylindrical core cavity which is closed at top and bottom also by reflectors. The outer face of the side reflector is horizontally supported by elements reacting against the thermal shield or pressure vessel liner. In the outer wall of the side reflector, the gaps (37) between adjacent graphite block columns are fitted with seals (42). Used in particular for a gas-cooled, pebble-bed reactor where core operating temps. of approx. 1000 deg.C result in displacements or distortions of the side reflector so that the initially tight joint between adjacent columns of blocks are opened up to form gaps. In the annular space outside the outer wall of the side reflector, comparatively cool coolant gas flows to cool the outer wall of the reflector and the thermal shield and/or liner. This gas is at a slightly higher pressure, typically 0.5bar, than the hot gas flowing down through the core and consequently considerable leakage could result into the core through the gaps. The provision of seals (42) largely prevents this inward flow of gas.

Title: Winding electric coil on coil former - involves position detector for comparison of actual and rated turn values and second detector for storage of specified values
Inventor: HOCK LOTHAR
IPC: H01F41/06
Filed: 1980-12-23
Abstract: The winding is carried out by a wire guide moving between the boundary flanges of the coil former, using a control device with a turns counter, acted upon by two position detectors allocated to the flanges. The number of windings to be coiled forms an instantaneous value which is compared with a stored value derived from the number of turns per coil layer. The comparison of the instantaneous value with the number of turns starts with each response of one position detector. The number of turns, associated to one position detector, and that associated to the other position detector meet specified turns related to the ratio of the distance of the last turn of the coil from one flange to the distance of mutual flange spacing, as well as to the number of turns per layer. The instantaneous value, smaller than the respective number of turns is stored in a further memory as a number of turns for the reverse winding run.

Patent DE-3106705-A1 (DE)
Title: Drive units for locomotion means and conveying means
Inventor: POISEL OTTO KARL DIPL ING
IPC: H02K7/116
Filed: 1981-02-23
Abstract: The invention of the drive units consists in the fact that each unit is composed of two core group units (1) a double-sided electric motor (2) with two integrated transmissions (3) and two continuously operating variable transmissions (4). The core group units (1) develop in the operating state a thrust force which is coordinated in one direction which, when transmitted to inactive systems, permits them to move. A gyroscopic bearing of the drive unit ensures any desired change in direction of the thrust force. The drive units are dependent on an electrical power supply, can produce a thrust force whose size can be varied and are characterised by a high degree of efficiency, a minimum noise level and a zero value of exhaust gas. By virtue of these properties, they are perfectly suitable as drive units for cars and lorries, railways and ships but mainly for drive systems for air travel and space travel and for armaments technology.   <IMAGE>

Title: Oscillating piston internal combustion engine
Inventor: HECKMANN HORST L DIPL ING
IPC: F02B53/02
Filed: 1981-05-06
Abstract: The invention relates to an oscillating piston internal combustion engine, which essentially comprises two pairs of polygonal pistons (2a, 2b; 3a, 3b), which engage claw-shaped in one another and oscillate to and fro in a pivotably mounted cylinder (4) enclosing them. The combustion forces are transmitted to a crankshaft by means of connecting rods by way of shafts, running inside one another and mounted in a crankcasing, and by way of levers fitted on these, the crankshaft in turn, by way of a gear drive, setting the cylinder into a rotation determined by the valve timing. Figure a, b, c diagrammatically shows the operating principle during a 180 DEG crankshaft rotation/90 DEG  cylinder rotation. Figure a: ignition device (11) ignites the gas in chamber (14). Figure b shows the process after a 90 DEG  crankshaft rotation. The gas is compressed in the working chamber (15), drawn into chamber (16) through the inlet port (12) and in chamber (17) burnt gas is expelled through the exhaust port (13). Figure c shows the situation after a 180 DEG crankshaft rotation. Here the compressed gas is ignited in chamber (15). Further working strokes follow in accordance with the rotation of the cylinder. <IMAGE>

Title: Process for cleaning chemisorption filters, preferably for removing SO2 downstream of power stations, waste incineration plants and the like
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D53/04
Filed: 1981-05-09
Abstract: In the case of chemisorption filters which contain layers of chemisorption compositions arranged on filter cloths, the filters had previously been cleaned intermittently. Fresh sorption composition was then applied to the filter cloths. If too thick a layer of the chemisorption composition had built up on a filter cloth, the layer thickness was reduced by actuating the cleaning mechanism, but it was impossible to prevent an involuntary effect on adjacent filter cloths. In the process according to the invention, cleaning is effected continuously during the entire chemisorption activity of the filter. This involves working with variable cycle frequencies as a function of the pressure difference before and after filtering.

Title: Variable valve timing mechanism for four stroke internal combustion engines
Inventor: LORENZ ERNST
IPC: F02B75/02
Filed: 1981-07-15
Abstract: The subject of the invention is a valve rocker arrangement for the engine speed-dependent valve timing of internal combustion engines in which the individual cams on the camshaft have a profile varying in the longitudinal direction and, if necessary, also in a transverse direction. In order, by simple design means, to obtain an overlap of the opening times varying precisely as a function of the engine speed, each valve rocker (1) is supported in a bracket (1), which is supported in the cylinder head so that it can swivel about a vertical central pivot. The centre axis of the central pivot passes through the bearing surface of the valve tappet on the valve rocker arm, the other valve rocker arm running on the cam by means of a roller. A control element (5) is coupled to the bracket (2), which element swivels it according to the engine or camshaft speed of rotation, so that the valve rocker roller runs on a cam path specially designed for this speed, in which an optimum overlap occurs at any given time.   <IMAGE>

Title: Energy from magnetism
Inventor: HECHFELLNER FRANZ JOSEF
IPC: H02K55/00
Filed: 1981-10-26
Abstract: A permanent magnet induces a continuous current in a superconducting coil. According to Lenz's Law, the permanent magnet is repelled by the magnetic field generated by the coil. Outside the region where the magnetic field acts, the polarity of said permanent magnet is reversed and it is brought back into the area where this field acts and is attracted by the coil. The magnetic field of the coil is caused to break down by means of a superconducting short-circuit switch, and the process is repeated. The energy to be applied is provided by a mechanism and the energy obtained or released is stored. The invention represents a possible solution to the energy problem. <IMAGE>

Title: DC motor without a commutator
Inventor: WEHDE HEINZ DR RER NAT
IPC: H02K29/00
Filed: 1981-11-25
Abstract: The subject-matter of the invention is a DC disc-rotor motor without a commutator, consisting of a disc-shaped rotor with a plurality of axially magnetised permanent magnets which are arranged in the edge region of the discs on a rim and have alternating polarity, and of a stator, which supports a winding, which is opposite the rotor magnet rim, has at least two phases and consists of a plurality of turns, on at least one supporting part which is offset axially with respect to the stator and is used as the magnetic return path. The invention is based on the object of increasing the efficiency of such a motor. This object is achieved in that the strands of the winding running in the direction away from the rotation axis are constructed with increasing width and reducing axial thickness, and in that the surface of the magnetic return path ring, on which the coils lie, is arranged inclined with respect to the rotor plane such that an effective air gap which becomes smaller radially towards the exterior is produced between the rotor magnets and the magnetic return path ring. <IMAGE>

Patent DE-3201367-A1 (DE)
Title: Electrical resistance heater comprising PTC resistance elements
Inventor: HILLINGER ERICH
IPC: H05B3/48
Filed: 1982-01-19
Abstract: Electrical resistance heaters designed for lower powers or comparatively low temperature ranges are often fitted with heating elements made of PTC resistance materials. Such heating elements have the property that, as the temperature rises, their resistance increases and a self-regulating effect, which renders expensive regulating or limiting devices unnecessary, consequently sets in. The continued serviceability of such heaters, however, requires the heat generated by the heating elements to be removed as rapidly as possible to avoid any build-up of heat in the elements. Such a build-up of heat leads to a rapid rise in temperature, and this results in the self-regulating effect setting in too early. The present invention avoids such a build-up of heat by mounting the PTC resistance elements between two parallel extruded bars, made of aluminium or the like, which make contact with the elements, encasing the PTC resistance elements and the extruded bars with insulating material and surrounding this structure with a metal sheathing tube which compresses it.
Patent DE-3202916-A1 (DE)
Title: Sheeting basket for the sheeting of a duct trench
IPC: E02D17/08
Filed: 1982-01-29
Abstract: Sheeting baskets for the continuously progressive sheeting of duct trenches generally consist of two rigid formwork walls which are held at a distance from one another and can be pushed through the earth via hydraulic cylinders. When the formwork walls are pushed through the earth, complicated and usually not very effective supporting devices have to be provided in order to avoid sinking of the sheeting basket at the front side. The invention shows a constructive way of avoiding this sinking. This is achieved by the formwork walls being divided in the longitudinal plane and being connected merely via guides and by double-acting hydraulic cylinders being arranged between these formwork walls. <IMAGE>
