Title: Carbon electrode vibration mould - with solid and annular upper plungers for smaller diameter extrusion
Inventor: WILKENING SIEGFRIED DR
IPC: B30B11/02
Filed: 1973-04-09
Abstract: Graphitized carbon electrodes of round form, for use in electric arc furnaces are produced in cylindrical moulds with an attached vibrator. The green carbon mass is first compacted in a mould of larger dia. and an outer hollow cylinder plunger is then lowered into it while a solid inner plunger is raised. This transforms the electrode to the desired smaller cross-section. This procedure achieves a better consolidation of the electrode mass and imparts to the electrodes a marked axial texture. it is less critically dependent on temp., plasticity, size consist and binder percentage of the green electrode mass.

Title: Waterproof sound-absorbing sealing strip for bath edges etc - is of angled shape to fit against wall and support ceramic tiles
Inventor: PAULI WILLI
IPC: A47K3/00
Filed: 1974-04-22
Abstract: This bath sealing strip is angled so that the arm adjoining the wall is provided with a double-sided adhesive tape whilst the arm of the strip resting on the upper edge of the bath is provided on the underneath with longitudinal grooves, the depth of which is no more than 2/3 the thickness of the angled arms. Along the edge where the two arms meet there is an upward protrusion which can be formed by a flange or by the angled arm adjoining the wall protruding beyond the horizontally extending arm. After fixing in this strip tiles can then be cemented to the wall so that the bottom tile rests on the horizontal arm of the strip. Any protruding edge of this horizontal arm can then be torn off to provide a flush seam with the tile which is then grouted in the normal way. Should any water penetrate this seam it is prevented from reaching the wall on account of the other angled edge.

Title: Operation method for accumulators with grid conductor plates - is based on terminal potential measurement and discharge interruption
Inventor: SUNDBERG ERIK GUSTAV
IPC: H01M10/44
Filed: 1975-02-20
Abstract: The lead-acid accumulator has one or more cells where the conductor grids in the negative electrodes contain a metal with a higher conductivity than lead and which in the electro-chemical series is more positive than lead and/or in the positive electrodes contain a metal which is more negative than lead. During the discharge of the accumulator the terminal voltage and/or at least a single potential is continuously measure against a reference electrode. The discharge is interrupted at such a terminal voltage or at such an electrode potential so that no damaging quantities of the other metal are emitted from the electrode grid. The discharge may also be interrupted just before the emission of the other metal from the electrode grid occurs.

Title: Twisting electric stranded cables - driving cable winding head at least at changes of twisting pitch or direction in the direction exerted by strands
Inventor: AHLVERS DIETER
IPC: D07B3/00
Filed: 1975-03-12
Abstract: Cables twisted from strands are wound onto a mandrel and the mandrel is driven in the direction exerted on the mandrel by the strands at least at the beginning of the winding process. Method is for winding electric cables or telecommunication cables onto mandrels following twisting of strands and prior to coating with insulation and protective sleeves. Winding of cables leads to relaxing of stresses in the strand, prevents twisting of cables or strands and leads to low noise level in communication cables.

Title: O-ring seal with high resilience - has core of coiled wire spring enclosed in sheath of flexible plastic
Inventor: LANGER FRITZ
IPC: F16J15/3284
Filed: 1975-04-16
Abstract: An O-ring seal has a core made from a length of coiled wire spring. The wire (4) is of rectangular cross-section with the dimension chosen to give the required resilience of the O-ring. A gap (5) is formed between successive coils equal to about one tenth of the width of the wire section. The ends of the coil are joined together to make a torus and the ring is then enclosed in a sheath of plastic such as P.T.F.E. This sheath may be formed by wrapping a piece of platic sheet around the coil to form several layers. Alternatively separate sheets may be used, the ends of each sheet being butt welded together.

Title: Combustion process for rotary piston engines - water oil emulsion in injected after ignition
Inventor: FRANKE WALTER
IPC: F02B53/02
Filed: 1975-06-04

Patent DE-2526685-A1 (DE)
Title: Plastic synchronizing ring for gear coupling - has relative angular movement between thrust ring and coupling gear
Inventor: BIBBENS WILLIAM H
IPC: F16D23/02
Filed: 1975-06-14
Abstract: A gear change synchronizing system consists of a thrust ring (16) made from plastic, which is located on the periphery of the coupling gear (12) with internal teeth. Circumferential locating grooves (24, 26) in the thrust ring and coupling gear allow relative angular motion but prevent any relative axial movement between the two components. When the operating fork (32) moves the thrust ring (16) axially, the coupling gear is also shifted until part of its length is in mesh with the external gear (42), thus providing the required coupling.
Patent DE-2530312-A1 (DE)
Title: Winding automatic guiding and pressing device - is used during winding of axially advancing windings for electric appliances and applies axial and radial pressure
Inventor: HARTWIG HORST
IPC: H01F41/082
Filed: 1975-07-08
Abstract: Axial and radial pressure elements are applied to the winding. They are held under pressure through a transmission mechanism including a support sliding over the whole length of the winding stand on guiding bars and pressed against counter-pressure by a pneumatic or hydraulic piston-cylinder system. The pressure is independent from the pressure element travel distance and acceleration. Power transmission between the piston-cylinder system and the above support is done by a running chain or other mechanism and the piston-cylinder system is mounted at the end of the winding stand. If the pressure elements are unintentionally lifted, a device makes the axial advance inoperative.
Patent DE-2535294-A1 (DE)
Title: Cleaner for suction dust filter in closed weighing vessel - allowing discharge of weighed material with min. residue
Inventor: LESK ADOLF
IPC: B65G53/60
Filed: 1975-08-07
Abstract: The device comprises a valve which periodically opens and closes the air outlet chamber of the vessel and which is pref. mounted at one end adjacent to the air outlet opening. The valve may be made of resilient material e.g. rubber and provided with an adjustable weight, with an adjustable distance between its moulding and the air outlet opening. Material entering the vessel falls to the bottom of the vessel, while the dust-entraining conveying air flows through a filter cloth and out through a pipe towards a fan. At the end of the conveying process, the direction of flow is reversed, causing the previously upwardly curved filter cloth to hand down and eject part of the filter cake. The air is then caused to reciprocate due to increases and decreases in pressure, which open and close the valve, causing displacement of the filter cloth.

The edge of the drinking-trough (h) can be jagged or have oak-leaf or acorn-shaped decorations round it. The base of the drinking-trough (h) can be flat; or slope upwards from the inside outwards so that rain or water collects in it. Alternatively, the trough (h) may slope down towards the outside so that water collects around the edge in a channel. The drinking-trough (h), feeding-tray (c) and vase (a) can be connected by plug connections. The whole assembly can be dismantled. When turned round by 180 deg. hundred and eighty degrees, the roof-drinking trough (h) can be used on both sides.
Patent DE-2547964-A1 (DE)
Title: Inert gas welding piston fed with electrode wire - has vibrating gas nozzle preventing deposition of weld spray on or in pistol
Inventor: MANFRON ARMANDO
IPC: B23K9/29
Filed: 1975-10-27
Abstract: The pistol is fitted with a vibrator, so that the wall of the gas nozzle is subjected to periodic or continuous vibration. The vibrator is pref. operated electromagnetically, hydraulically, pneumatically, or by an electric motor. A pref. pistol uses an electric motor to rotates a cam, which oscillates two spring strips with bend end knocking against the nozzle. In one design, the gas nozzle is fixed on the head of the pistol by a PTFE bush. In welding using a consumable electrode wire, weld spray is deposited on the front end and the bore of the gas nozzle, blocking gas flow which causes weld defects; welding must be stopped while the nozzle is cleaned. The invention eliminates such problems.
