Title: Document file for computer print=outs - has support, as vertical surface with right angles stand, and two mutually-inclined surfaces, offset in steps
Inventor: LEIBIG JOACHIM DIPL ING
IPC: A47B23/04
Filed: 1979-07-24
Abstract: The reading of computer print-outs presents reading difficulties due to the size of the print-out sheets and the flat visual angle resulting from this size. The holder, removing these difficulties, has a vertical surface (1) with an orthogonally bent surface (2) forming its standing socket. Two inclined, large surfaces (3,4) form support surfaces for the computer print-outs. The narrow surface (5) forms a step and supports the paper sheets on the upper support surface (3), preventing sliding of the file. The lower edge border of the large surface.

Title: Electric butt welding of thick metal cable, esp. aluminium wire - which is welded, upset, and then cold rolled and annealed to make strong joints
Inventor: ROTTA ROMAN
IPC: B23K11/02
Filed: 1979-08-25
Abstract: Both ends of two wires or profiles are pressed together to make a butt joint, which is then hot upset (I) to increase its dia. Cold working is then used to reduce the butt joint to the required size. After cold working, the upset zone is pref. subjected to a recrystallisation-anneal (II). Upsetting (I) is pref. undertaken at min. 450 deg.C to increase the cross-section by 40%, esp. inside an insulating tube. Cold working of the upset joint is pref. achieved via rolling; and anneal (II) is pref. at min. 400 deg.C. The welds are extremely reliable, both electrically and mechanically, so they are very suitable for protective circuits or earth wires.

Title: Low radioactivity concn. steam heating circuit - esp. for heating radioactive effluent is detected by filter and detector
Inventor: MEININGER SIEGFRIED ING GRAD
IPC: G21D5/12
Filed: 1979-12-21
Abstract: A heat transfer system comprises heat exchangers (6,8,9) for heating a radioactive medium, more specifically the cooling water of a pressurised water reactor, using heat supplied by a heat carrier in a sec. circuit, more specifically a sec. steam and water circuit. This sec. circuit (10) contains a filter (20), together with an activity meter (27) connected to the filter. Where the sec. circuit is a steam and water circuit comprising a condensate line, the filter (20) is incorporated in this line, more specifically downstream of a condensate cooler (16). The filter may be an ion exchange filter with a mechanical filter (32) connected upstream of it. Used in particular where a steam/water circuit is used for heating radioactive cooling water from a nuclear reactor, esp. pressurised water reactor in the radioactive effluent treatment plant (5). The steam may be generated in an auxiliary sec. circuit (1,10) produced in an auxiliary boiler building (2) physically sepd. from the reactor building or reactor ancillaries building (3). The arrangement ensures that extremely low levels of activity in the sec. steam/water circuit are detected, partic. because they become highly conc. in the filter. At the same time the filter removes them from the circuit.

Title: Turbocharged IC engine lubrication system - with starter actuated electric circuit for auxiliary oil pump which supplies floating bearing through filter
Inventor: SAITO FUMIO
IPC: F01M1/20
Filed: 1980-01-23
Abstract: The I. C. engine has an exhaust gas turbocharger and has a main oil pump (2), driven by the engine, which supplies a lubricant through a filter (5) to the gallery (6) and to the floating bearing (16) of the exhaust gas turbo charger. In addition, an auxiliary oil pump (21) with a separate suction strainer (3') is driven from a battery when a contact (24) is closed every time the starter is actuated. This auxiliary pump fills up the filter (5) and its piping through a non-return valve (25). The result is a much faster supply of oil to the floating bearing (16) of the exhaust gas turbo charger. Bearing seizures can thereby be eliminated and the oil pressure of 2 kg/cm2 required for the floating bearing is quickly reached.

Title: Combustible gas generating reactor - with cyclone feeding fluidised bed to crack noxious components
Inventor: LINNEBORN HANS DIPL ING
IPC: C10J3/56
Filed: 1980-04-19
Abstract: A combustible gas is produced from fine to coarse grained and/or short-fibre fuels, specially of organic origin, in a reactor in which the fuel particles are introduced into a continuous fluidised bed of min. height. Gas and vapour prods. are kept in the bed for a min. residence time so that the gas components, which are capable of forming tar-like condensates, are cracked. This produces a gas, free from noxious components, at a much increased reaction output in smaller reactors.

Title: Measuring operating life of capacitor - using programmable unit receiving charging data and contg. theoretical lifetime data
IPC: G01R31/01
Filed: 1980-05-30
Abstract: An arrangement measuring the already used part of the theoretically expected total life of a capacitor is esp. for the capacitor bank of a defibrillator. This enables the capacitors to be replaced before reaching the end of their useful life as normally experienced by a failure. A variably programmable unit contains the characteristic data for the theoretically anticipated capacitor lifetime. The unit receives a signal proportional to a variable related to the capacitor life. The output of the programmable unit provides the input to an electrolytic counting and display device. The latter shows the used part of the capacitor life on a non-volatile indicator. The life indicating variable may be the capacitor charge voltage or the number of charging cycles.

Title: Prodn. of shaped zeolite aluminosilicate bodies - from a mixt. of calcined clay precursor bodies and aq. alkali soln. contg. aluminosilicate seed
Inventor: BROWN STANLEY MONTY
IPC: B01J29/06
Filed: 1980-07-29
Abstract: Coherent composite zeolite bodies comprising a mixt. of crystalline aluminosilicate zeolite dispersed in an amorphous alumina-silica porous residue of anhydrous calcined kaolin, are made by: mixing calcined kaolin clay precursor bodies with aq. alkali, and heating to convert the calcined kaolin clay to zeolite dispersed in alumina-silica, the heating being carried out in the presence of amorphous aluminosilicate nucleation centres. The mixt. may be aged prior to heating. Used in a wide range of catalytic and adsorptive processes. Presence of nucleation centres during heating densitises the growth of crystalline zeolite to variations in the source of clay used to form the bodies and to variations in the calcination conditions used to produce the bodies. Prods. also have good strength and attrition resistance.
