Patent DE-2529737-A1 (DE)
Title: Supply independent braking for electric traction - with field current from braking resistances and from battery
Inventor: CIESSOW GUENTER
IPC: H02P3/12
Filed: 1975-07-01
Abstract: The electric locomotive is fitted with a fails safe regenerative braking system in which for normal braking the field current for the motors is taken from a tapping in the rectifiers (5) linked to the supply (4), which may be AC or three phase. If the supply fails then the braking current for the field coils is taken from the current flowing through the braking resistances (1) using a static inverter (6) To initiate the braking effect, with no supply voltage present, the current is taken from the integral battery (7) using a DC converter (10). The current drain on the battery is thus kept to a minimum, ensuring fail-safe braking even for repetitive braking on long downhill sections with the supply off.

Title: Paint scraping roller for walls and ceilings - with uniform scraping depth, saving scraping time and subsequent plastering has link rod suspension
Inventor: ZITZELSBERGER MAXIMILIAN
IPC: B44D3/16
Filed: 1975-08-06
Abstract: A paint scraping roller for walls and ceiling comprises two guide rollers made of rubber or plastics at the inner ends of which are four opposed round pins for inserting or mounting the rollers. There is a ridge roller on the surface of which are formed four integral opposed round ridges. At both ends of the ridge roller are four opposed round holes. Link rod suspension means are formed on the lower side in a slide plate. A trowel is provided with a pressure blade on the perpendicularly bent end of which is a rubber or plastics coating. The roller facilitates scraping, which it performs with uniformity, and saves subsequent plastering of hair cracks. It also reduces to a min. the amount of pressure to be applied, and can be used by anybody. Its parts are interchangeable to allow easy cleaning.

Title: Tartar separation from wine or must - by ultrafiltration to remove crystallisation inhibitors before stabilisation and liq. reconstitution
Inventor: RHEIN OTTO H
IPC: C12G1/09
Filed: 1975-10-27
Abstract: Tartar sepn. comprises first subjecting the must or wine to ultrafiltration, to separate liq. portion contg. crystallisation inhibitors as a concentrate. Filtrate is then subjected to a standard tartar stabilisation process, e.g. cooling, reverse osmosis or electrodialysis. After tartar sepn., the stabilised filtrate is recombined with the concentrate. Process is pref. carried out in closed system. Pref. air is excluded or protective N2 is used. The re-constituted liq. differs from untreated liq. only as regards tartar content, but neither in appearance, nor taste. In absence of crystallisation inhibitors, e.g. polysaccharides, proteins, polyphenols, tartar excess can be sepd. more quickly from filtrate.

Title: Electronic ignition system for IC engine - has solid state components and transmitter and control section with HF proximity switch
Inventor: HIMMELHEBER ERNST HEINRICH ALB
IPC: F02P3/08
Filed: 1975-12-18
Abstract: The control is for the electronic ignition system for a spark ignition engine using solid state components. No mechanical changes will be necessary on the distributor and any variations in the ignition setting will be smoothed out by an electronic control circuit. The control circuit will take account both of thermal and electrical effects. The control circuit consists of a transmitter and a control section. It uses a high frequency proximity switch. A metal component approaches the inductive field of an oscillator, increasing the damping of the inductance. The oscillations will start to spread at a given value of the damping and will start to repel the metal component. This characteristic of the oscillator is used as the switching criterion.

Title: Coder with A=D conversion to binary - has coder, decoder, feedback circuit and function generators giving rising or falling signals
Inventor: KULIGOWSKI GERD ING GRAD
IPC: H03M3/02
Filed: 1976-08-05
Abstract: Binary signals are decoded by a feedback circuit in the coder, to whose input binary signals are applied. Its output is connected to a first input of a comparator. Analogue signal is applied to its second input. The decoder is based on the feedback circuit in the coder. The coder feedback circuit has a function generator (V2, V3, C4, C5), which delivers a rising or falling output signal when the binary signal has its first or second binary value respectively. this signal is applied to the comparator (VGL) second input (2) with such polarity, that the difference between this voltage and input analogue is a minimum. The decoder has a function generator similar to that in the coder (V2, V3, C4, C5). Binary signals are applied to it, and the analogue signal is collected from its output.

Title: Blood purifier involving semipermeable and absorbent filters - for removal of toxic and urogenous metabolites from a small blood volume
Inventor: WALCH AXEL DR
IPC: A61M1/36
Filed: 1976-09-02
Abstract: A pu rifier extracts toxic metabolites and/or urogens from blood in which the blood passes through a passage between a selectively permeable membrane and an absorbent material enclosed in a porous membrane. The purifier comprises alternate layers of permeable membrane and enclosed absorbent in helical or serpentine layers normal to flow paths of the blood between the layers. Used to obtain the combined effects of dialysis/diafiltration through selective fermentation and haemoperfusion through an absorbent simultaneously. The overall capacity of the system is relatively small, reducing the volume and residence time of blood outside the parent body. The selective membrane extracts water, electrolytes, urea, ammonia, etc. The absorbent fixes toxic metabolites.

Title: Heavy vehicle automatic transmission - has retarder regulated by torque converter control valve to inhibit it during gear change
Inventor: ELTZE ULRICH DIPL ING
IPC: F16D65/78
Filed: 1976-11-19
Abstract: The hydraulic retarder (10) of the heavy vehicle is fitted to the drive shaft from the automatic transmission, and behind the torque converter. The control valve for the torque converter is also linked to the control pressure for the retarder so that the retarder is inhibited during gear change. This relieves the gear change servo elements from additional torque due to retarder braking. The system provides a smooth gear change as well as a smooth braking control, with the retarder and engine braking effect combined smoothly.

Title: Concrete embedded ground anchor - has anchor tube of diminishing wall thickness to maintain uniform axial compression
Inventor: SCHUETTE HANS-JOACHIM DIPL ING
IPC: E02D5/76
Filed: 1977-02-24
Abstract: The ground anchor for concrete, has a body (2) to which the tension members (1) are attached, and an anchor tube (3). The anchor tube (3) is of nominally constant external diameter (Da), but is formed of tube sections of different wall thickness welded together, resulting in the tube strength declining with distance from the anchor body (2). The progressive reduction in cross-section of the tube wall results in uniform axial compression over the length of the tube, avoiding loss of bond due to excessive compression adjacent to the anchor body (2). Alternate sections of the tube have saw-tooth and helical external surface forms for an effective bond with the surrounding mortar (5).

The 1st conveyor runs at a speed (V1) and 2nd conveyor at a speed (V2) adjusted so that V1=V2 cos alpha. Each of the hot electrodes is supported transversely by two carriers on chains and is taken over by two carriers on the 1st conveyor. During the motion on the first conveyor the welding takes place, the fim being seamed and cut, befor the electrode is taken over again by the rising 2nd conveyor; te supporting points of the electrodes on the carriers of chains being offset from the circumference of the chain wheels. Works continuously without stopping for the welding operation.
