Patent DE-2128315-A1 (DE)
Title: Cut-textile widths - esp cut-to-size textiles for ready-made clothes
IPC: A41H43/00
Filed: 1971-06-17
Abstract: Cut-outs for ready-made clothes and cut-to-size plastic film, artificial leather, etc. for upholstery are made by laying out the material and rewinding it after determining faults in the material. The material is laid out in several lengths in accordance with its total length and the material is rewound after determining its faults. The lengths are determined in such a manner w.r.t. the total length that faults are eliminated with min. loss of material, and the material is then laid out and cut into sections in accordance with the predetermined sequence.

Title: Purification of exhaust gases - by using rich mixtures absorbing hydrocarbons and catalytically oxidising carbon monoxide
IPC: F01N3/00
Filed: 1971-06-12
Abstract: Internal combustion engines are operated using fuel-air mixts. in wt. ratios of 1:12.5 - 11.0, the exhaust gas cooled to above the dew pt. of water, the unburnt hydrocarbons adsorbed on a layer of granular active carbon and the CO oxidised over a catalyst. Pref. the adsorbed hydrocarbons are desorbed from the carbon by air and drawn back into the engine. Use of richer mixts. than the usual fuel-air ratio of around 1 : 14.5 prevents formation of oxides of nitrogen. Better utilisation of fuel by 5-20 % is achieved. The need for temps. of 750-900 degrees C, which are difficult to maintain in motor vehicles, for catalytic reduction of nitrogen oxides, is eliminated.

Title: Mould conveyor track - with telescopic mould platforms
Inventor: TACCONE RUSSELL W
IPC: B22D33/00
Filed: 1971-08-02
Abstract: The conveyor comprises a number of sections which at adjoining ends engage each other forming a continuous unit. It also comprises means for moving these sections in the direction of conveying and reducing the length of the track to a smaller length than the row of moulds on it thereby permitting their being pushed into a pit, etc. The track is also displacable in such a way as to extend the length of the conveyor platform surface to accept fresh moulds in addition to the moulds already on it so that the whole row can be displaced on the track together with the displacable section. The conveyor is intended for transfer of relatively weak moulds from casting to stripping without danger of their collapsing during transfer as a result of handling.

IPC: C04B7/04
Filed: 1971-08-06
Abstract: Loss of F in mfr. of H2SO4 and cement from waste CaSO4 from H3PO4 mfr. is prevented by treating the crude powder or its individual components, consisting of waste CaSO4, SiO2-, Al2O3- and Fe2O3-contg. material, with sufficient (hydrated)lime or CaCO3 to neutralise the H3PO4 liberated on heating and give a fixation of the F content of the calcined material corresp. to the lime addn. Max. retention of F in the calcined material is achieved, by addn. of pref. 0.4-1.5% CaO in form of CaO, Ca(OH)2 or CaCO3.

Title: Treating refinery sludges - by two-stage extraction to recover wax and oil
Inventor: COLE EDWARD LAWRENCE
IPC: C10G73/36
Filed: 1972-11-25
Abstract: Refinery sludge is deoiled, dewatered and dewaxed by (1) mixing the sludge with a light aliphatic hydrocarbon (pref. a 3-5C alkane), separating the mixt. into water of reduced COD, water-waxy solids slurry and an oil-aliphatic hydrocarbon phase, heating the latter phase to above the critical temp. of the aliphatic hydrocarbon under a pressure to keep the aliphatic hydrocarbon in a dense phase so splitting the oil-aliphatic hydrocarbon phase into aliphatic hydrocarbon and oil portions which are recovered, and (2) separating water from the water-waxy solids slurry, mixing the waxy solids with a light aromatic hydrocarbon (e.g. benzene or cumene), separating the resultant mixt. into wax-free solids, and a wax-aromatic hydrocarbon phase and recovering wax from the latter phase. The wax-free solids may be used as land fill, the recovered wax can be decoulourised, and the oil recovered in step (1) is clean and suitable for feeding to a cat cracker or for blending with fuel oil.

Filed: 1973-02-19
Abstract: Prodn. of pure nuclear fusion in which D2O or a critical mass e.g. 21H + 31H which cannot expand during energy absorption by h .alt theta, is brought about by holding a completely degassed liq. sample (as above) in a reaction chamber in sucha wa that this can experience a volume expansion either on freezing or on energy absorption (h alt. theta) while a hydraulic pressure counteracts proportionally the tendency of the sample to expand.
Patent DE-2321978-A1 (DE)
Title: Forming horizontal row of ingots - using a tilter frame, esp. for transport to a soaking pit
Inventor: HONERMANN GEORG
IPC: B22D29/00
Filed: 1973-05-02
Abstract: A number of ingots are simultaneously transported to the filter frame where they are suspended and then allowed to fall. Pref. during falling the ingots are closed up together by guides so that when they hit the edge of a striker beam on the base of the frame they fall over and form a compact row which can be transported. This reduces manpower requirements since the number of ingots required to form a row in the stacking arrangement of a soaking pit can be handled simultaneously.
Patent DE-2332553-A1 (DE)
Title: Building components for making shuttering and temporary structures - is laminated timber beam whose ends have steel brackets
IPC: E04G11/08

Title: System for compensating out-of-balance weights - is for rotating discs and has additional out of balance weight and two compensating masses
Inventor: SCHWEIZER WALTER PROF DR
IPC: G01M1/04
Filed: 1973-09-21
Abstract: The design is particularly intended for instrument indicating dials. The addition of the supplementary weight provides static balance centralising the combined mass.

The supplementary weight is given by the product of the maximum primary out of balance weight and (1 + sec arc sin r/R), where r is the radius of the balance weights, and R is the radius of action of the balance weights. The supplementary weight is provided by increasing the weight of the pointer counter weight. Included is the method of centralising the combined mass, and also a lever mounting for the large balance weights.

IPC: A61M1/20
Filed: 1973-10-23
Abstract: Artificial kidney has a long tubular member to establish a blood path and consisting of a semipermeable membrane, on both sides of which are two carriers next to the path, each with a row of projections of struts running along the carrier and path and distributed at a spacing over the width, overlapped and spaced between the projections of the other carrier. The tubular element is given a zigzag shape over its width, and the carriers and tubular element establish channels or passages which extend along the path. The overlap of the projections is such that they clamp off the tubular element to separate the blood flow channels running along the path. The apparatus uses a spirally-wound Cellophane (RTM) tube for dialysis or oxygen saturation of blood.

Title: Windscreen wiper and wash system - has rear windscreen automatically washed at intervals corresponding to front wiper speed
Inventor: GOERTLER HORST
IPC: B60S1/48
Filed: 1974-03-08
Abstract: The rear windscreen wash/wiper circuit switch is regulated via the centre contact of the wiper motor park position switch. The rear wind screen wash pump and wiper motor is regulated by the front windscreen washer switch to give a reduction of 4:1 so that the rear wiper makes one cycle to every four front wiper cycles. The centre contact of the front windscreen wiper motor switch, park position is connected with the rear windscreen wiper wash system relay switch via an impulse reduction stage. The centre contact therefore gives regulator impulses for the relay switch corresponding to the front wiper cycles and speed, the impulses being small at interval drive, greater at low speed and considerably faster at full speed.
