Title: Sampling water through filter - esp for ph readings with automatic periodic backwashing of filter
Inventor: AXT GUENTER DR DIPL CHEM
IPC: G01N1/14
Filed: 1972-03-03
Abstract: Continuously abstracting a filtered liquid sample, e.g. for obtaining a pure water sample from a solids-polluted effluent flow, consists of passing a relatively large flow of the untreated liquid into a vessel from which the excess overflows or leaves, while a portion is drawn off through the filtering pipe. To backwash the filter intermittently , the vessel is intermittently emptied so that pure water backflows through the filter. Pref. the automatic periodic emptying of the vessel is effected by a syphon which is repeatedly primed by the excess flow of unfiltered liquid, and then has the syphon vacuum broken as the vessel liquid level drops. This process is automatically repeated and, in each cycle, the drop of liquid causes a backflow from the clean liquid extract pipe through the filter.

Title: False twisted yarn mfg - has an additional fibre introduction removed by solvent to give the bulked effect
Inventor: KITAZAWA SHIN-ICH
IPC: D02G1/02
Filed: 1972-06-19
Abstract: A yarn is mfd. from two fibre types with different melting points by a twisting and thermal treatment, with a fibre of a third type being introduced with a melting point lower than the fibre with the highest melting point and which dissolves in a solvent. The fibre strand is heated without contact to a temp. between the highest and lowest melting points of the fibres and given a false twist, followed by treatment with a solvent which does not affect the two main fibre types. The process gives a yarn which, when worked into a fabric, gives stability and hard wearing, a strong resistance to pilling with a light crimped handle, with good stretch and elasticity - particularly against pressure - giving a consistent looped surface and sheen.
Patent DE-2318363-A1 (DE)
Title: Automatic washing machine door lock - by pulse generator activating thyristor so capacitor/transistor shorts lock relay
Inventor: PETERS HANS-ECKART
IPC: D06F37/42
Filed: 1973-04-12
Abstract: An automatic washing machine has the door to the drum interlocked so that it cannot be opened until the drum has come to a standstill. The pulley of the drum drive actuates a pulse generator which controls a thyristor in series with a capacitor. The latter is kept charged by the drum rotation and keeps a transistor in parallel to a relay switched ON. When the drum has stopped, the relay is not short-circuited any more and attracts the plunger of a door lock so that the drum door can now be opened. This type of interlock is less troublesome than the centrifugal type and it has a lower response threshold for slower speeds. It acts quicker than thermal types and is more reliable and less complicated than the pneumatic types.

Title: Metal hydroxides or oxides having large specific surface area - produced by alkaline precipitation in presence of humic acid or humates
Inventor: MACH WALTER J DIPL PHYS
IPC: B01J37/03
Filed: 1973-07-09
Abstract: Prodn. of metal hydroxides or oxides having large specific surface area by pptn. from sq. solns. of metal salts by means of an aq. soln. of a base is improved in that one or both of these solnS. contain humic acid or a humate in a dry weight ratio metal oxide: humic acid of 8:1 to 800:1 (pref. 16:1 to 160:1). This method is esp. suitable for the prodn. of transparent Fe2O3 pegments, but can also be applied for mfg. of catalysts, chromatographic adsorbents and other matls. based on metal oxides. Alkaline pptn. results in the formation of very small particles (often colloidal size) because humic acid surrounds the metal hydroxide particles as soon as they fromed and thus prevents their further growth.

Title: Ribbon loom warp yarn supply system - has assembly of warp beams to feed loom zones where bands are woven
Inventor: KOCH GERHARD
IPC: D03D35/00
Filed: 1973-07-20
Abstract: The construction of a wrap beam support mounting system, partic. for a ribbon loom where typically some six waistbands 30-70 cm wide are being developed requiring six warp feeds, has a number of mounting points to secure the ends of the axes of the warp beams in a horizontal or vertical stack with eyelet boards to deflect the warp yarns to the loom. The system allows the supply of warps to be extended, beyond the conventional single beam to supply the loom, increasing the weaving time per warp beam as the effective length of warp supply is increased reducing time lost through beam changes.

Title: Anodic oxidation inside a hollow niobium component - having at least one opening, with externally located cathode
Inventor: DIEPERS HEINRICH DIPL PHYS DR
IPC: C25D11/26
Filed: 1974-02-27
Abstract: In a process for the anodic oxidation of the inner surface of a hollow body made of Nb using a suitable oxidising electrolyte and an electrical potential between the body and a cathode, the cathode is located outside the body and a sensor is used to detect the electropotential rel. to the body. When the electropotential corresponding to the required thickness of oxide layer is reached, the potential between the body and the cathode is so reduced that the electropotential during the succeeding oxidation process remains substantially constant. Process is used for prepn. of Nb components for use as super-conductors. The process is comparatively simple and eliminates disturbances in the oxide layer formed inside the body due to gas bubbles.

Title: Regeneration of motor oil in situ - by passing through cartridge of tightly wound tissue under pressure
Inventor: HEINZ HORST GUENTER
IPC: B01D29/07
Filed: 1974-04-09
Abstract: Motor oil is regenerated by recycling it under pressure through a filter cartridge mounted in a cylindrical housing. The cartridge consists of tightly wound porous tissue having a minimum surface area of 56,000 cm2 but which can be correspondingly larger for larger motors and engines. The principle applies for all i.c. engines. The filter is mounted on the engine block and therefore obviates removing the oil to regenerate it. The filter is capable of removing all the impurities which form in the engine oil (carbon, water etc.) and therefore giving the oil an almost unlimited life.

Title: Parallel-coupled static inverters - supply three phase load under control of single unit via transformer windings
Inventor: BOETTGER KLAUS DR ING
IPC: H02M7/48

Abstract: The static inverter circuit consists of two or more, parallel-coupled static inverters (1, 2) supplied from the same d.c. network (N) and controlled by only control unit (St). The 3-phase outputs of the two inverters are coupled to opposite ends of the 3-phase transformer's three windings. Tappings along these windings lead off to the single 3-phase load (L). If three inverters are to be run in parallel, then the tappings of the windings between the first two inverters are coupled to the ends of a second 3-phase transformer's windings. The second transformer's opposite ends are connected to the third static inverter's outputs.
