Patent DE-2821023-A1 (DE)
Title: Pulse shaping and smoothing circuit - converts binary signal with steep edges into rounded edge signal using clock pulse controlled binary computer
Inventor: HELLER ARTHUR DIPL ING
IPC: H03K6/04
Filed: 1978-05-12
Abstract: The position of the output signal smooth edges is derived from the input signal steep edges. The shaper consists of a series circuit comprising a digital permanent store and a digital-analogue convertor, with the store addressed through a clock pulse controlled n-place binary counter, so that at least one store area can be read out by n address bits (Ao-An). The area is programmed at one end by the output signal logic "zero" amplitude (Eo), and at the other by the logic "one" amplitude (E). It is programmed between the end values by the required amplitude variation. The counting circuit, started by the input signal abrupt change runs through the whole counting program.

Title: Hydraulic advancing mine support system - includes integral relief and pressure limiting valves controlling lifting and lowering of telescopic sections
Inventor: HEINZE HARRI ING GRAD
IPC: E21D15/44
Filed: 1978-05-18
Abstract: The advancing mine support system uses telescopic members which include a foot (2) for contact with the ground and an upper part (3) which can be connected to further similar sections. The uppermost section carries a valve (9) at the top for connection to a setting gun, and above this is a fitting (14) for attachment to an overhead beam, along which it can slide. The valve system ensures that the foot is lifted clear of obstacles during advance. Between the inner tube (3) and the outer tube (2) is an annular space (7) forming a chamber for hydraulic fluid. Projecting from the top of the outer tube is a housing (15) with a relief valve (16) and a pressure, limiting valve (17) controlling a channel (18) communicating with this annular space. These are connected to an external valve block.

Title: Removable protective sheathing for seat belt webbings - uses flexible fabric made pliable by impregnating with glue-like agent
Inventor: HOELTER HEINZ ING GRAD
IPC: B60R22/00
Filed: 1978-09-30
Abstract: The sheathing is removable for cleaning and suitable for retractor-operated automatic seat belts. For the sheathing to be fitted on the exposed part of the webbing, an elastic fabric is used in form of a length of strip wide enough to envelope with an overlap the width of the webbing. The fabric is soaked in a glue-type agent which makes it plastically pliable. In this condition, the strip (2) is wrapped around the width of webbing (3). When the glue-type agent sets, a sheathing is obtained which can be removed for cleaning.

Title: Fine adjusting method for photo-mask - includes changing temp. of disc by, e.g. peltier element, to rectify errors between it and associated mask
Inventor: WALTHER ALBERT ING GRAD
IPC: G03F9/00
Filed: 1978-10-11
Abstract: The adjusting and accurate positioning procedure is for discs in relation to a photo-mask for photolithography as used, e.g. in semiconductor technology. After the customary positioning process, the associated photo-masks are eliminated or reduced by changing the temp. of the disc. This change of temp. can be effected by a Peltier effect element. The temp. control can be carried out by certain output signals of an automatic disc adjusting installation. A dry gas cleaner can be assigned to the disc. Typically, a suction table (2) is used with bores (3, 4, 5) connected to a low pressure chamber or a vacuum pump. The upper surface of the table is formed as a Peltier element (6) with Peltier layers (7, 8) having their own terminals (9, 10).

IPC: D04B27/26
Filed: 1978-10-23
Abstract: The mechanism to give the selective alternating movement to the guide bars in a warp knitter has a tracer with the guide bar acting with a multitrack programme carrier. The tracer for the first programme carrier is keyed to the alternating motion for the guide bars. All the tracks of the first programme carrier have a common section in the same form for the tracer to change tracks. The guide bar is so keyed to the carrier for the pattern that an alternating movement change can take place while the machine is operating.

Title: Ruminant feed contains urea salt with Krebs cycle acid - esp. fumaric acid salts with one or two moles of urea, which release ammonia at a slower rate
Inventor: ROSSI JEAN
IPC: A23K50/15
Filed: 1979-08-02
Abstract: Ruminant feed contains a urea salt formed with a Krebscycle acid. The salt is pref. formed with fumaric acid and pref. salts are (=CHCOOH)2.2NH2CONH2 (I) and (=CH-COOH)2.NH2CONH2 (II). Cpd. (I) is a novel salt. Feeds normally contain 0.1-7 wt.% of the salt based on the total weight of dry materials in the feed. The salt may also be supplied as a concentrate contg. up to 50 wt.% of salt for mixing with feedstuffs. Provides ruminant feed which improves metabolism in the rumen. In 'in vitro' digestive tests the urea fumarate salt releases ammonia more slowly, than does a simple mixture of urea and fumaric acid.

Title: Radioactive wastes decontamination - by mechanical and bio-logical treatment followed by precipitation
Inventor: SCHULZ WERNER
IPC: G21F9/06
Filed: 1980-01-30
Abstract: The decontamination of the radioactive wastes, esp. those from a nuclear medical station where radioactive iodine and other radionuclides have contaminated the sewage, is based on a mechanical cleaning in series with a biological aeration treatment and pptn. in settling basins. The biological treatment is preceded by an acidification to reduce the pH-value below 6.5. In the biological station, the air blast removes a part of the radioactivity which is collected by an air filter. In the pptn. stage, the residual components are extracted by adding flocculants, precipitants or adsorbents. This succeeds in extracting from the effluents all radioactive components so that no environmental pollution arises. The new method uses no wearing or rotating parts so that maintenance is reduced to a minimum.

Title: Multiple junction circulator for microwaves - has unidirectional energy transfer using resistance layers to attenuate second harmonic
Inventor: GOLOMBEK WERNER DIPL ING
IPC: H01P1/383
Filed: 1980-02-21
Abstract: The circulator design for attenuating the second harmonic is suitable for multiple junction circulators connecting either coaxial conductors or hollow conductors and capable of increasing the attenuation of the second harmonic consists of ferrite discs (3) in a permanent magnetic field produced by magnets (5) with yoke (6) and pole shoes (22), the field being perpendicular to the propagation direction of the microwaves. A layer of resistive material (4) is placed on the ferrite discs. The presence of the resistance layers has a marked influence on the attenuation of the second harmonic content (7db higher than without the resistance layers) without affecting the fundamental circulator junction attenuation.
