Patent DE-2519331-A1 (DE)
Title: Control of intermediate spinning and draining between rinses - with more complete removal of dirty water, for programmed household washing machine
Inventor: HOHMANN SIEGFRIED
IPC: D06F35/00
Filed: 1975-04-30
Abstract: Intermediate spinning and draining in between rinses in a programme-controlled household washing machine is controlled by continuously pumping ot the water during intermediate spinning, pref. in combination with high drum speed. After the intermediate spinning stage has been switched off, pumping out of water is continued for a further given period e.g. 20-40 secs. This method obtains the same results after 3 rinses as conventional methods do after 4 rinses, thus saving time and fresh water which amounts to 25-30 l. in a conventional household machine. Due to complete removal of the water given off during spinning, the amount of rinse water for the next rinse can be reduced. A time delay member set for a given time can be connected to the switch for switching off the drain pump, and is switched on simultaneously with switching off of the motor which drives the drum during spinning.

Title: Ultra high frequency leaky coaxial cable - has outer conductor with slots arranged at a predetermined pitch
Inventor: NAKAJIMA IWAO
IPC: H01B11/18
Filed: 1975-05-30
Abstract: The leaky coaxial cable is for use at ultra-high-frequency and has, between an outer conductor having slots for the radiation of electromagnetic wave and a protective sheath covering the ouer conductor, a dielectric layer with electrically low loss, thereby decreasing the transmission loss. By arranging the slots of the outer conductor in a predetermined relation, it is possible to provide a leaky coaxial cable having a wide band characteristic and less transmission loss. The phase constant of the waveguide is determined from Floquet's theorem.

Title: Combined physico-chemical removal of oxygen consuming materials - from water streams having physical and ozone stages
Inventor: DIETRICH KARL ROLF DIPL CHEM D
IPC: C02F1/78
Filed: 1975-07-01
Abstract: Physical and chemical process for effluent water treatment involves precipitation, adsorption, flocculation or flotation either alone or in various combinations coupled with a chemical treatment with O3. By this means values difficult or normally impossible to achieve for BOD, COD and 'TOC' (English equivalent uncertain) caused by oxygen consuming components in the water can be achieved by oxidising the residual dissolved materials with O3 after removing the solids. Used for treatment of effluents and waste waters contg. materials which are difficult to destroy by biological fermentation processes. This is particularly true of dissolved coloured matter. Moreover, the sludge produced by such, biological processes is often difficult to remove and handle The process reduces the total chemical oxygen demand by physical sepn. processes and then only the residual dissolved material need be treated. This reduces the O3 consumption. 50% of the COD can be removed by the physical sepn. alone.

Title: Butterfly valve with eccentrically mounted flap - has expansible metal sealing ring held on flap by retaining ring
IPC: F16K1/228
Filed: 1975-07-23
Abstract: The flap (1) locates in a cylindrical conduit incorporating a ring (13) on its inner wall (12), the flap bearing on this ring to effect closure and aligning in a plane parallel to the conduit axis when open.

This metal ring is of greater internal dia. (Dr) than the groove dia. (Ds) and is thus, able to deform elastically and radially during clamping of the retaining ring. The metal ring is composed of three annular discs with the outer discs projecting beyond the inner disc.

Title: Non-agglomerating iron oxide pellets - produced by coating green pellets with finely divided iron ore and firing at high temp.
Inventor: GOETZMAN HAROLD EDWARD
IPC: C22B1/24
Filed: 1976-10-08
Abstract: The Fe oxide pellets do not agglomerate rate when used in a vertical reduction counterflow shaft furnace. They are formed with cross-section dia. of 0.63-1.9 cm. from iron ore or concentrate of 0.5-3% SiO2, 7-12% moisture, 96.5-99% Fe oxide, and 1% bentonite as binder. A surface coating is formed on the pellets from finely divided Fe ore, excepting hematite ore; the pellets are dried and preheated before the formation of a hard coat by heating for 5-15 mins. at 1149-1343 degrees C. The process avoids the formation of lumps without the use of mechanical devices in the shaft furnace or the introduction of unwanted materials.

Title: High definition microfilm recording system - processes gray scale of each original by linear or non-linear characteristic controls using film of high contrast and resolution
Inventor: CLAUSEN CLAUS-DIETER ING GRAD
IPC: G03B27/72
Filed: 1976-12-04
Abstract: The high definition microfilm recording system uses film having high contrast and resolution to store alpha-numeric and other information in a compact lay-out. The gray scale of each original is processed by linear or nonlinear characteristic controls for max. information readout. The high definition emulsion is similar to that used for holograms or x-ray film. The original can be reprocessed electronically by a t.v link to generate the required contrast. This process enables a contrast range of at least grade 3 to be reached which is diagnostically relevant for the evaluation of x-rays.

IPC: C01B21/02
Filed: 1976-12-29
Abstract: Very pure N2 is prepd. from the off-gases of cumene (I) oxidn. by increasing the dwell time of the air or air-O2 mixt. introduced into a reactor of min. height 15m, such that the off-gases contain is not >2, pref. 0.3-1 vol. % O2. The off-gases are then treated to remove organic impurities, residual O2, CO2 and moisture. The oxidn. is carried out at 70-135 degrees C and 2-20 atmos. excess pressure to a cumene hydroperoxide (II) content of 5-30 wt. %. The pure N2 prod. is suitable for all industrial purposes. By using a reactor 15-25m long, almost complete O2 utilisation is achieved and there is hardly any loss in yield or capacity.

Title: Robot for electric resistance spot welding - where robot arm carries welding transformer so only short sec. leads are required
Inventor: POLLMANN WERNER DIPL ING
IPC: B23K11/31
Filed: 1976-12-31
Abstract: Welding robot for the electric resistance spot welding of sheet metal parts, uses >=1 driven, multijoint arm ending in a welding transformer, which is in close proximity to the welding electrode(s) also located at the end of the arm. A flexible cable carries the mains voltage power supply to the transformer, which provides the low voltage used in resistance welding. The mains power supply is pref. fed to a stationary frequency converter so the mains frequency is increased to 200-1000 Hz, esp. 200-400 Hz, before reaching the transformer. Used for mass prodn. spot welding using =15,000 amps. By locating the transformer near the electrodes, the use of long, heavy, water-cooled cables carrying the sec. current is eliminated. The use of an increased frequency provides better inductive coupling of the iron core in the transformer; only a thin, cable of low wt. is needed to carry power to the transformer.
