Title: Thermodynamic machinery drive motor - is energised by local heat source and has thermostatic capsule operating ratchet wheel with spring return
Inventor: SCHNONHARDT PETER
IPC: F03G7/06
Filed: 1980-03-12
Abstract: An expansion type thermostatic capsule (1) is in contact with a sleeve (4). In one position the sleeve is in contact with a heat source (8) and transmits heat to the capsule. As it expands, the capsule moves a lever (13) against a spring (11) force. The lever moves a ratchet pawl (14) to turn a wheel (15). At the same time a linkage (17,19) connected to the lever, moves the sleeve away from the heat source. The capsule then cools and the spring returns the mechanism to its starting position, with the sleeve in contact with the heat source. During this movement the pawl slides over the ratchet wheel without turning it.

Title: Organic carbon and nitrogen removal from waste water - by biological degradation, nitration and denitrifying in plant contg. immersed percolating filters
Inventor: STENGELIN VOLKER DIPL ING
IPC: C02F3/08
Filed: 1980-05-02
Abstract: Organic C and N are removed from waste water by biological organic C decomposition and by NH3 oxidn. to gaseous N2, by passing, in radial or axial flow, through a biologically working multi-step waste water clarifier contg. immersed percolating filters. Novelty consists in reducing the growth area of the individual immersed percolating filter rollers exposed, to air-O2/time, from step to step, according to purification progress. This is achieved either by (a) reducing the growth area surfaces projecting out of water or (b) by lowering the speed of rotation of the immersed percolating filter rollers, or by combining (a) and (b) in required proportion. In the claimed waste water clarifier, the immersion depth of the immersed percolating filter rollers increases from step to step. The speed of rotation of the immersed percolating filter rollers falls in proportion to the falling growth area exposed to air-O2. A separate denitrifying step is not needed.

Title: Process for producing fuel-containing bricks
Inventor: MORGANTE JUN WILHELM
IPC: E04C1/40
Filed: 1981-01-31
Abstract: Fuel is supplied to the centre of the melt stream of an extruder for producing fuel-containing extruded bricks. This has the consequence that the shaped bricks have a fuel content decreasing from the centre outwards. In this case, the marginal zones may remain free from fuel. As a result, an adequately high fuel concentration is possible, so that to a great extent there is no need for any supply from outside from the heating of the kiln.

Patent DE-3112444-A1 (DE)
Title: Method and arrangement for producing a smoothed sequence of measurement signals
Inventor: NEY HERMANN DIPL PHYS
IPC: G01D1/00
Filed: 1981-03-28
Abstract: In producing measurement signals from the temporal pattern of physical processes, for example speech signals, measurement errors occur for various reasons which produce individual measurement signals which differ significantly from adjacent measurement signals. For the further processing of measurement signal sequences of this type, for example for comparison with a reference sequence, a smoothed sequence of measurement signals is required in which ideally only the erroneous measurement signals are eliminated while the remaining signals are unchanged. This is achieved according to the invention by calculating an intermediate value from each measurement signal compared with each preceding measurement signal and by deriving a smoothing value from the minimum intermediate value and by storing the ordinal number of the preceding measurement signal in which the minimum of the intermediate value occurs. The measurement signals which are selected for the smoothed sequence are identified from the sequence of these stored ordinal numbers. <IMAGE>

Title: Device for reducing the refresh cycles for dynamic memories
Inventor: GUDE MICHAEL
IPC: G11C11/406
Filed: 1981-10-30
Abstract: In the case of dynamic memories, the stored information must be refreshed at the latest after certain time intervals, as otherwise a loss of information can occur. Since this refreshing comprises reading and re-writing a line of memory, additional time is required for this. The aim of the invention is to minimise these lost times. This is achieved by departing from previous concepts and detecting separately for each memory line whether it is imminent that the refresh time will be exceeded (Fig. 2). The respective memory line is refreshed again only just before this time elapses. Consequently, the minimum of refresh cycles for the memory is achieved. It is advantageous in this case that whenever the memory is addressed frequently, additional refresh cycles can be virtually dispensed with. <IMAGE>
