Title: Gas electrofilter with wet separation - having lime and chlorine in the wash liquor and additional steam injection
Inventor: HOELTER HEINZ
IPC: B03C3/16
Filed: 1974-08-02
Abstract: Electrofilter for gas cleaning with wet separation has the degree of dissociation in the gas impurity improved and also its tendency to agglomerate, by the injection of a condensible vapour, esp. water. This is done before or into the electric part of the separator. The gas to be dissociated can also have other chemical additives injected. For use in conjunction with DT 2425324 where gaseous impurities (e.g. SO2, HCl) are removed using an electrical separator to dissociate the gases and then washing with a lime soln. (calcium hydroxide) to which chloride ions have been added. The use of steam (or other condensable vapour) improves the dissociation and thus increases either the efficiency of the unit or its capacity.

Title: Wedge plate spacer element with retainer cage - has no horizontal movement when installed between floor and machine
Inventor: BUGDAHN ERNST
IPC: F16M7/00
Filed: 1974-10-10

Title: Bridge structure carriage way surface - with insulating bonding layer of thixotropically fluid state setting plastics
Inventor: ROBINSKI BENNO
IPC: E01D19/08
Filed: 1974-10-26
Abstract: The carriage-way coating for laying on bridge structures incorporates an insulating layer of bonding material in the form of hardening plastics, into which gravel, or other suitable granular material, is scattered and spread before the layer has set; after this a road surfacing layer is placed on top. Here a plastic which is thixotropically adjusted in its fluid state is used for the binding layer, so as to make it possible to lay the road surfacing in a series of rapidly and directly following operative processes, without sacrificing the means of preventing the formation of fissures which might otherwise appear at a later stage, scattered granular material being prevented from penetrating down to the carriage-way slab.

Title: Phenyl biphenyl carboxylates or biphenyl benzoates - as additives to liq crystals for dielectrics for electronic components
Inventor: STEINSTRAESSER ROLF DIPL CHEM
IPC: C09K19/48
Filed: 1975-08-06
Abstract: Biphenyl estes of formula (I): where X is -CO-O- or -O-CO- and R' and R2 are (un)branched 1-8C alkyl or alkoxy groups are used for prepn. of liq. crystals, esp. dielectrics for electronic components. They cannot be used alone in electronic indicators for use at room temp. because of high m.pt. (>90 degrees C) and clear points (>170 degrees C), but as additives to other liq. crystals they cause lowering of the m.pt. and increase in the clear point, without great increase in viscosity. Pref. esters have a nematic phase and a smectic phase and are esp. those in which X is -CO-O-. Many liq. crystals which have an unsuitable temp. range of the nematic mesophase can be used as dielectrics in admixt. with I. Dielectrics with positive or negative dielectric anisotropy can be obtd. by suitable choice of the initial liq. crystal.

Title: Continuous knit goods stabilising process - uses steam chamber to ensure that spread edges do not curl in further treatment processing
Inventor: SCHUIERER MANFRED
IPC: D06C3/06
Filed: 1975-10-21
Abstract: In the continuous treatment of a moving fabric web, partic. knit goods for garment manufacturing, the edges of the fabric are first spread out. After the fabric edges have been unrolled, and the fabric spread out, the material is exposed to steam for a short time span in a bell-shaped air-free steaming chamber, before passing on for further processing. The curcled edges of the fabric are spread out by using rollers or compressed air jets. The spread fabric has a dwell time of 2-60 seconds in the steam chamber, which has an internal temperature of 95-98 degrees C, and is fitted with a perforated carrier to support the fabric as it passes through. The process stabilises the unrolled edges of the fabric so that the material remains fully spread while passing into the further treatment zone.

Title: Metal working process for L sections - uses roller with peripheral groove and shaping bar
Inventor: STEYN BENJAMIN MULLER
IPC: B21D5/08
Filed: 1975-11-26
Abstract: The L-section (10) passes between rollers (22, 24) rotating on parallel axes (X1, X2). One roller has a peripheral groove with a right-angled cross-section.

Title: Overvoltage protection on transformer tapping windings - operates by connecting voltage limiting elements between phases of tap selector
Inventor: STEIN WERNER DR
IPC: H02H7/055
Filed: 1976-04-27
Abstract: The tapping windings (1, 2, 3) of a three-phase transformer have tap positions (7, 8, 9) which can be selected by a selector arm (10, 11, 12) and load switch (13, 14, 15). To assist in limiting transient overvoltages between phases voltage limiters (16, 17, 18) are connected between phases on the selector arms. With this arrangement the insulation thicknes and clearance between windings and switches can be reduced without undue risk as the overvoltage level is now controlled to a definite limit. The limiters are typically voltage sensitive resistors or spark gaps in series with resistors. These elements are in addition to those normally placed across selector arms or individual windings.
