Patent DE-2656109-A1 (DE)
Title: Bipolar electrode made of titanium and steel - for filter press electrolysis cells used in mfg. chlorine and caustic soda
Inventor: PETERS EDWARD JOSEPH
IPC: C25B11/02
Filed: 1976-12-10
Abstract: The electrode consists of a coplanar anode, anode back plate, cathode, and cathode back plate, all spaced apart. Spaced conductor strips are located between, and fixed onto, the back plates. The anode and its back plate are pref. made of Ti, whereas the cathode and its back plate are made of steel, and the conductor strips are made of copper. The Cu strips are pref. fixed on the back plates by explosion cladding, using a gap of >=25.4 um between the Cu and the plate, and an explosive with detonation speed 120% of the metal with the highest speed of sound. The explosive is ignited so detonation proceeds parallel to the conductor strips, and the collision pressure of the strips and the plate is higher than the elastic limit of the metal with the lower elastic limit. The electrode has sufficient free space to permit the generation of H2 without the latter causing embrittlement of the Ti anode back plate.

Title: Pretreatment of wool fibre to improve spinning property - using resin, esp. polyamide-epichlorohydrin! condensn. prod., or oxidising agent
IPC: D01H13/30
Filed: 1976-12-29
Abstract: The spinning characteristics of wool fibres on rotary spinning machines are improved by pretreatment of the fibres for redn. of scale with a scale-occluding synthetic resin or by an oxidising agent for partial removal of scale structures. A synthetic rresin with a higher surface tension than that that of wool or carrying a positive charge in comparison to the negatively charged wool is used. Used for the more efficient processing of wool in rotary spinning machines and the avoidance of scale-build-up. Removal of scale ensures a smoother spinning process, producing an undamaged yarn superior in mechanical tenacity and dyeing properties.

Title: Extending table top for furniture - rests on drawer fascia panel when fully drawn out on frame
Inventor: WIESMANN HERBERT LUDWIG
IPC: A47B1/05
Filed: 1977-05-13
Abstract: The extending table or work top (1) has an extending leaf (3) mounted inside the drawer-like frame (12). The upper side (34) of the fascia panel (11) of the drawer is deeper than the surface of the table top (1) by the thickness of the extension plate. When extended, the leaf lies level with the table top and is supported at the back on the frame by one or two tilting fitments (13, 14). At the front, it rests on the drawer fascia panel (11). This allows the leaf to be drawn completely out to lie flush with the table top and yet still have a high stability. Each tilting fitment preferably has a control lever attached to the rear part of the frame (12) which at its front end has a rocker arm (24) which guides and supports an extension rail (17) attached underneath th leaf. A spring biased bolt (28) attached to the control lever (21) acts with a locking member (37) on the furniture unit to secure the plate in the extended position.

Title: Endless wire cable - has core ends abutted and six strands helically about core, with reduced dia. strand ends spliced into the core
Inventor: SCHEFFLER GUENTER DIPL ING
IPC: D07B1/06
Filed: 1977-06-27
Abstract: Endless wire cable is produced by winding six wire strands about a core whose ends are abutted, and the ends of the strands are spliced into the core. To prevent pulling out of the strands from the core, the outer dia. of the strand ends which are spliced is reduced and the ends are spliced with the core by winding the strands several times to locate the strand ends frictionally under induced tensile stress.

Title: Triggering threshold for alarm of radiation dose meter - can be varied by inputting pulse series
Inventor: GIRLE HANS-DIETRICH
IPC: G01T7/12
Filed: 1978-09-20
Abstract: The triggering threshold of a radiation dose meter which comprises a digital counter for recording the accumulated dose and an alarm signal triggering device is adjusted or reset by feeding the adjusting or reseting input, which is connected to the digital counter of the dose meter with a pulse series which is equal to the difference between the counter state (Zo) set in the dose meter for triggering the alarm signal and the counter state (Zw) which corresponds to the new, desired threshold. Specifically, in the pulse series the pulses are many times shorter than the gaps between pulses. Used esp. for a portable or personal radiation dose meter, where it may be necessary to readjust the alarm threshold due to previous exposure of the individual to radiation within a previous defined period.
