Patent WO-03083761-A1 (WO)
Inventor: CUYLEN MICHAEL
IPC: H03M7/22
Filed: 2003-03-17
Abstract: The invention relates to a method for coding a sequence of data bytes (BY1,BY2), wherein respectively two bits (B1, B2) of a data byte form a double-bit (D1-D4) and each double bit is represented by a time-slot frame (ZR1-ZR4) having at least four time-slots (ZS1-ZS4) which can assume an on' value or an off' value (Z1,Z0). The coding occurs in a time-slot frame such that at least one time-slot is preassigned an off' value at a position (AF) and the non-preassigned time-slots comprise a maximum one time-slot with a single on' value in order to form a logical value (00,01,10,11) of a double-bit. Said method can be used advantageously in identification systems (IS), in mobile data memories (DT) and in writing/reading devices (SLG). The advantage thereof is that an increased data rate and/or a greater transfer distance can be achieved between the writing/reading device and the mobile data memory.

IPC: C10L9/00
Filed: 1970-05-02
Abstract: Thecoke is treated with gases contg. hydrocarbons the composn. and temp. being such that the hydrocarbons and/or their decomposition products deposit on the coke and/or react with constituents of the coke. A pref. gas mixture consists of hydrogen and a hydrocarbon eg. methane in such proportions that a part of the hydrocarbon splits up in contact with the coke into carbon and hydrogen. By use of a low reaction temp. a carbon black which is difficult to ignite is obtd. The gas mixture is heated to a temp. above that of the coke before admission, in order to obtain the maximum carbon deposit, and may also be pre-heated by contact with the discharged coke. Reactivity of the coke product is reduced, the sulphur content is lowered, and heat of the discharged coke is utilised.

Patent DE-2061552-A1 (DE)
Title: Press for continuous extrusion - with easily changed punch nose
IPC: B21C33/00
Filed: 1970-12-15
Abstract: In a press for making continuous extrusions from separate superimposed billets, the nose of the punch is normally connected directly to the puch body and has from 1-6 mm play in the blank holder. This play is reduced to 0.3 mm by fastening the nose of the punch on to a rod that passes down the centre fo teh punch in which it is free to float, except for the final one seventh of its length which fits tightly in the base of the punch to which it is secured by a nut. Thus, lateral movement of the punch nose is not limited by friction between nose and punch. The nose can also be changed without removing the punch from the ram.

Title: Cleaning a filter cloth - without interrupting its operation
Inventor: KOLL WILFRIED
IPC: B01D46/04
Filed: 1972-01-04
Abstract: The filter cloth is stretched by a compression spring (alternatively a tension spring) acting at its centre from a fixed mounting point, and is attached to the mouth of a feed pipe. A cam is arranged below the cloth so that, when it first rotates, it acts against the spring and relaxes the cloth. Further and rapid cam rotation jerks the cloth back into its stretched position by spring pressure, releasing material trapped on the cloth. The device is suitable for an air filter in the evacuation of gas from a screw press which feeds plastic material to processing equipment.

Title: Electrochemical oxygen probe for (engine) exhaust gas - has porous protective coating catalysing attainment of gas equilibrium
Inventor: TOPP BERNHARD
IPC: G01N27/407
Filed: 1972-02-10
Abstract: Electrochemical probe for determining the O2 content of exhaust gas, esp. from internal combustion engines, employs an O2 concn. chain with ion-conducting solid electrolyte in the form of a tube sealed on one side. The outer surface has an electron-conducting coating catalysing attainment of the gas equilibrium and then a firmly bound, porous, temp.-resistant protective coating. The improvement is that the protective coating consists of a material catalysing attainment of the gas equilibrium. The protective layer can consist of Cu-Cr oxide doped with BaO or Ni oxide, La-Co oxide doped with Sr oxide or a catalytically inert porous material contg. catalytic material in the porous surface. It is 5-500 mu m thick. The contact area and therefore the contact time are large enough to the components of the gas mixt. to attain thermodynamic and equilibrium. Damage to the electrode layer e.g. on applying the porous protective coating or during operation, does not change the sharp voltage break at lambda =1 into a gradual voltage change over a greater lambda range.

Abstract: A catalyst for battery electrodes, esp. control electrodes and gas-consuming electrodes for lead accumulators, where the catalyst consists of tungsten carbide, the individual grains being coated with an extremely thin layer of Ag amounting to 0.1-5 wt.% (pref. 0.5-2.5%) of the catalyst. Electrodes made with this catalyst can be heavily loaded, react quickly to hydrogen, and can be used as the hydrogen electrode in fuel cells with acid electrolytes. The electrodes contain 10-30 wt.% conducting material, esp. graphite, 20-40 wt.% thermoplastic binder, and 30-70 wt.% catalyst. Tungsten carbide (grain-size 5-20 microns) is added to a 5% aq. soln. of sodium boranate and stirred until all the boranate has decomposed on the catalyst; AgNO3 is added resulting in a ppte. of Ag on the carbide which is then washed and dried. A suitable electrode compsn. is 40 wt.% catalyst, 30 wt.% PTFE, 20 wt.% graphite and 10 wt.% potassium chloride (71-100 microns). The mixt. is pressed into electrodes, sintered at 150-300 degrees C., the pore-former dissolved out and the electrode activated in 6 n KOH.

Abstract: Glass of compsn. 10-70% B2O3, 5-65% SiO2 and 5-40% Na2O, K2O and/or Li2O is used as an oxidation protective cover for molten metals such as brass. The glass has a low m.pt. so that its viscosity is low at the working temp. hence it flows freely over the surface of the melt allowing additions to be made and gas bubbles to escape readily yet not entering the melt.
Patent DE-2324596-A1 (DE)
Title: Explosion-welding of external fins and ledges on tubes - where explosive detonated in bore forces tube onto fins held in prestressed housing
Inventor: BIESINGER JUERGEN DIPL ING
IPC: B23K20/08
Filed: 1973-05-16
Abstract: This technique can be used to join materials not normally regarded as weldable, e.g. components for aero and space applications. To join e.g. four longitudinal fins at intervals of 90 degrees round a tube, four heavy segments are used to form a cylinder and sections are cut out in the bore, at the joint faces, (i.e. at 90 degrees) so that the profiles mate with the profiles of the fins (the profiles of the fins can vary, the only requirement being that their cross-section is matched by cut-outs). In this way, the fins are supported by the cylinder along their entire length. Two half-shells are mounted outside the segments with belts so that the segments are pre-stressed. The tube to be welded to the fins is placed inside the cylinder, and a uniform layer of explosive on the bore of the tube is detonated so that the tube wall is forced onto the fins. The bore of the cylindrical segments is coated with an inhibitor to prevent welding occurring except at the desired points. Spiral fins can be produced by this method.

Title: Activated sludge treatment tank with central aerator - has controlled removal of excess floating sludge from clarification chamber
Inventor: GAUSLING ALFRED
IPC: C02F3/12
Filed: 1973-05-16
Abstract: An activated sludge sewage treatment plant comprises a circular tank, subdivided by a hanging, annular wall into a central aeration chamber and an outer, annular, V-section clarification chamber. A central standpipe with bottom opening near the tank floor contains a centrifugal pump for aeration. Radial pipes having floating or height-adjustable intakes in the clarification chamber drum off excess floating sludge and return it to the standpipe in the aeration chamber. In addn., >=1 sludge draw-off pipes, height-adjustable, lead from the clarification chamber to a shaft outside the whole tank; a separate return pipe fitted with a centrifuged pump leads back from the shaft to central stand-pipe; there is no short-circuit between these two extra pipes, and the liq. drawn off by the first has sufficient residence time in the shaft for the sludge to be floated off before effluent is returned through the return pipe to the standpipe. Pref., a height-adjustable weir in the shaft isolates the first pipe from the return pipe. The entire shaft and the sludge trap may be combined as a single unit, interconnected by a valved line. Excess sludge can be removed from the clarification chamber at a controlled rate.
