Title: Process for introducing solids into hydraulic conveying systems and twin charging vessels
Inventor: KUHN MAX ING GRAD
IPC: B65G53/30
Filed: 1981-11-06
Abstract: The introduction of coarse-grained heterogeneous solids, to be conveyed hydraulically, into hydraulic conveying systems is carried out in such a way that the solid is alternately filled in the low-pressure range into vessels filled with water and then conveyed in the high-pressure range from these into the pipe. To enable this process to be carried out without blockages, it is provided that, when the solid is filled into the vessel, a solid/water ratio of about 1:1 is set which, during discharge, is increased preferably to 1:3 by controlled addition of pressurised water. In the equipment required for carrying out the process, a proportioning device (12), associated with the solids feed, with flow and time control is provided above the vessels (1, 2) alternately connected to the pressurised water line (4) and the conveying line (3) or to the solids feed (5) and the excess water line (6), and a pressurised water line (20, 21) is introduced in the region of the upper rim (18) and of the bottom (22). <IMAGE>

Title: Process and device for the biological purification of phosphate-containing waste water
Inventor: REIMANN HANS DR
IPC: C02F3/30
Filed: 1982-02-23
Abstract: In the process, the waste water is treated with gas in an activation tank in the presence of activated sludge for the degradation of organic hydrocarbon compounds and for the uptake of phosphate by microorganisms present in the activated sludge, the waste water/activated sludge mixture is withdrawn from the activation tank and fractionated in a secondary sedimentation to give a purified, essentially phosphate-free water and phosphate-containing sludge; a device for carrying out the process is also described. A part-stream is branched off from the waste water/activated sludge mixture leaving the activation tank and is subjected to an anaerobic phosphate elimination. At least part of the low-phosphate sludge produced from the phosphate elimination is returned into the activation tank, while the phosphate-enriched liquid is further treated.

Patent DE-3211436-A1 (DE)
Title: Shower tub with cladding
Inventor: WARCHOL ULRICH
IPC: A47K3/40
Filed: 1982-03-27
Abstract: The cladding panels (3) are held by means of bearing arms (6) which project away from legs (1) bearing the shower tub (W). Situated at each end of the bearing arm (6) is an insertion sleeve for insertion of the legs (1), into which sleeve the legs (1) fit positively. Each insertion sleeve has on its outside contact surfaces for the cladding panels (3). On one of the two passage sleeves, the contact surfaces are further away from the inside walls of the sleeve than on the other insertion sleeve. Due to the positive engagement of the legs in the insertion sleeves, the precise alignment of the contact surfaces is produced without adjusting work. Due to the different position of the contact surfaces, identical bearing arms (6) can be used for attaching cladding panels (3) of different thicknesses. <IMAGE>

Title: Discharge resist method for printing cellulose-containing textile materials with the production of two- and multi-tone effects
Inventor: JANSSEN WERNER
IPC: D06P5/12
Filed: 1983-01-17
Abstract: In a resist printing method, cellulose-containing textile materials are locally printed using at least one resist printing paste which in the case of white resists, for example sodium formaldehyde sulphoxylate or formamidinesulphinic acid as reducing agents, contains a thickener based on alginate, starch ether or plant seed gum and if appropriate sodium carbonate and, in the case of coloured resists, additionally contains vat dyes, then uniformly wet-on-wet overprinted using a printing paste for printing the ground, which contains at least one reactive dye, a thickener based on polyacrylic acid, sodium hydroxide and potassium carbonate, after which the printed materials are dried, steamed, washed and optionally subjected to an oxidative after-treatment and then finished by, for example, soaping, rinsing, hydroextraction and drying. If appropriate, the resist printing paste can additionally contain a benzylating discharge agent, triethanolamine and, in the case of white resists, an optical brightener and/or a sighting dye and the paste for printing the ground can additionally contain, for example, urea, a reduction inhibitor and an anti-foam, urea optionally being required for materials containing regenerated cellulose. According to the process, two- or multi-tone effects are obtained on the textile material, whose patternings exhibit extremely sharp outlines without haloes and have excellent levelness.

Patent DE-3312791-A1 (DE)
Title: Steam boiler with preheating of feed water and combustion air
Inventor: WIESER RUDOLF DR
IPC: F23J15/06
Filed: 1983-04-09
Abstract: The invention relates to flame tube boilers and industrial water tube boilers fired by natural gas, in which an additional cooling of the flue gases is performed outside the boiler by at least one feed water preheater and a hydraulically coupled combustion air preheating plant in two stages. It is possible as a result to achieve exhaust gas temperatures of 100 DEG C (or 90 DEG C), something which is not possible normally in the case of feed water preheating. The fuel heat is thus utilised up to just at the limit set by the risk of dew-point corrosion, which is particularly low in the case of natural gas (substantially less than 100 DEG C). In this case, there is no need to replace the existing burners on steam boilers which are retrofitted with these devices for improved flue gas cooling, and this keeps the conversion costs low. It is also possible to keep the increase in the reduction of draught on the combustion air and flue gas sides low, as a result of which the rise in electric power consumption is also only small. Gas-fired steam boilers which already have feed water preheaters, but whose exhaust gas temperatures are still too high (e.g. 150 DEG C) can, in addition, still be fitted with a hydraulically coupled combustion air preheating plant, as a result of which a further 2-3 percent of fuel can be saved. <IMAGE>

Title: Optoelectronic component, in particular a laser diode or a light-emitting diode
Inventor: ENNEN HELMUT DIPL PHYS
IPC: H01L33/00
Filed: 1983-05-26
Abstract: A laser diode or a light-emitting diode has a semiconductor crystal doped with lanthanides (4f ions). As a result of doping InP, GaAs, GaP, Si and Ge with lanthanides, incoherent radiation can be produced in the case of a light-emitting diode and coherent radiation in the case of a laser diode. The wavelength of this radiation is longer than the energy gap of the host crystal and is primarily determined by the 4f ion (lanthanide) and not by the energy gap of the semiconductor. Doping with erbium yields an emission wavelength of 1.54  mu m for the semiconductor component and this corresponds approximately with the minimum attenuation wavelength of a glass fibre such as those used in glass-fibre communication. <IMAGE>

Title: Vibration damper acting as a function of the load
Inventor: GRUNDEI MANFRED
IPC: B60G15/06
Filed: 1983-08-26
Abstract: The present invention creates a vibration damper acting as a function of the load in that the recoil force of at least one spring supported on the vehicle body is exerted on a damping valve acting both in a tensile and in a compression direction. The spring supported on the vehicle body may be the vehicle spring itself or it may be a spring supporting a part. Allowing additional bump stops to act on the damping valve is also feasible so that, for example, starting from a certain compression travel of the piston rod the bump stop increases both the spring force and the damping force.
