Patent DE-3121509-A1 (DE)
Title: Hard gold-plating bath
Inventor: WIDMANN ERWIN
IPC: C25D3/48
Filed: 1981-05-29
Abstract: The invention relates to a gold electrolyte for gold-plating plug contacts in electrical plug connections. The bath contains gold in the form of potassium gold cyanide. In the case of assemblies in electrical appliances which are connected together by plug connectors, a high contact quality in relation to volume resistivity and abrasion resistance of the contacts is required. These are usually ensured by means of an electrodeposited hard-gold layer. At the same time, the electrolyte must be technically simple and economical to use. For this purpose, according to the invention, malic acid is used as conducting salt and nitrilotriacetic acid is used as complexing agent in the electrolyte, in addition to the basic constituents potassium hydroxide and cobalt sulphate. Such a gold electrolyte is suitable, in particular, for gold-plating plug contacts in plug connectors for data technology.

Title: Brake-spring coupling for adjusting gears, especially of seat-setting devices
Inventor: ENGELS BERND
IPC: B60N2/22
Filed: 1981-11-23
Abstract: A brake-spring coupling for adjusting gears, especially of seat-setting devices in motor vehicles, has a shaft mounted fixedly in terms of rotation in at least one bearing, to which a brake drum is fixed. There bears frictionally against the outer surface of the latter a first helical torsion spring, of the bent ends of which one can be loaded by a driving member with the effect of reducing the pressing force against the brake drum and can be pressed against the stop face of a transmission member arranged fixedly in terms of rotation on the shaft. The other end can be loaded with the effect of increasing the pressing force by means of the transmission member. To reduce or eliminate play when the coupling is closed, there is provided a second helical torsion spring (10) which is laid against the same brake drum (1) as the first helical torsion spring (9) or against a second sheet-metal drum arranged coaxially with this first brake drum (1; 101) and connected at least fixedly in terms of rotation to it. One end of the second helical torsion spring and one end (9') of the first helical torsion spring (9) are connected free of play to the transmission member (6, 7, 21, 22). When the first helical torsion spring (9; 109; 209) is loaded by means of the transmission member with the effect of increasing its pressing force, the second helical torsion spring is loaded with the effect of reducing its pressing force and, in the opposite direction of rotation of the transmission member, with the effect of increasing its pressing force, whilst the other end (10'') and the end (9'') of the first helical torsion spring loadable by the driving member (11), but in the opposite direction, can be loaded by the driving member with the effect of reducing the pressing force and can be pressed against a stop face (19, 20) of the transmission member. <IMAGE>

Patent DE-3212939-A1 (DE)
Title: Axial face seal
Inventor: KUPKA DIETER
IPC: F16J15/36
Filed: 1982-04-07
Abstract: In axial face seals with pairs of rings, in which one ring revolves with the shaft and slides with one front face against the front face of another, non-revolving ring, the revolving slip ring of a pair of rings is made axially displaceable by means of a piston which does not revolve with it and can be displaced axially under the action of a gaseous or liquid pressure medium. Compared with an older proposal, in which the non-revolving supporting ring itself was designed as a piston of this kind, this makes possible the use of inexpensive, commercially available, standard axial face seal elements at least in the region of the stationary supporting ring. <IMAGE>

Title: Multi-circuit liquefier
Inventor: HAUSSMANN ROLAND DIPL ING
IPC: F25B39/04
Filed: 1982-05-21
Abstract: The invention relates to a multi-circuit liquefier for refrigerating installations with mutually independent liquefier trains which are arranged in parallel, two and more trains being connected to form mutually independent liquefier circuits. In order to avoid numerous difficulties of the previous system, the aim of the invention is to manufacture a multi-circuit liquefier which constitutes a considerable improvement both with regard to the material requirement and with regard to the capacity. To this end, the multi-circuit liquefier (cf Fig. 4) is constructed from elements which are in each case constructed from 1.5; 2; 2.5; 3; 4; 6; 8 or 9 trains which, in relation to pipe diameter, connection, as well as structures in the inside of the tubes which create pressure losses, are calculated in such a manner that at nominal capacity all elements, via the refrigerant-side pressure loss, are assigned precisely that refrigerant mass flow which can be completely liquefied in the elements. The refrigerant mass flow is in this case adapted to the tube diameter and the tube length in such a manner that the product of the inner heat-transfer number and the logarithmic temperature difference between refrigerant and air represents an optimum.

Patent DE-3230490-A1 (DE)
Title: Centrifugal immersion compressor
Inventor: KNOTT FRANZ JOSEF
IPC: F04C19/00
Filed: 1982-08-17
Abstract: In contrast to conventional reciprocating and rotary compressors, it is the displacement principle which is used in the centrifugal immersion compressor. For this purpose, air bubbles (compression chambers) are immersed in accelerated liquids, i.e. liquids under an internal pressure. This condition is produced in the minimum space in a centrifuge with a pressure- and liquid-free centre and a liquid ring, in which the internal pressure rises to a greater or lesser extent outwards due to the radial force. This construction thus allows a relatively high compression during a working stroke. Due to the high speeds, not only balancing but also the pressure decrease are problematic. The air compressed in the outer liquid ring passes via immersion bells and pressure lines into the centric centre, from where it is passed on via a rotatable take-off. A further possibility is to flange on a pressure vessel, which rotates simultaneously during filling. This compressor can also be used as a gas/steam turbine with a high combustion pressure. In this case, the fuel could be in liquid or dust form. <IMAGE>

Patent DE-3300726-A1 (DE)
Title: Process and apparatus for obtaining simple sugars and soluble lignins from lignocellulosic plant material
Inventor: CONCIN ROLAND DR
IPC: D21C3/00
Filed: 1983-01-05
Abstract: In the process, the plant biomass is forcibly treated in a pressure vessel with pure water in the liquid state at temperatures between 240 and 340 DEG C and under a pressure between 34 and 180 bar, with the water and the plant biomass passing through the pressure vessel batchwise or continuously. An effect which occurs only above a certain temperature is utilised in obtaining the final product. Whereas the hydrolysis reaction in the temperature range between 140 and 260 DEG C is essentially a surface reaction, there is a sharp change in the conditions above a value of 280 DEG C. The high temperature and the high pressure result in the biomass material dissolving almost completely within a few seconds to give a homogeneous mixture of saccharides and lignins.
Patent DE-3300887-A1 (DE)
Title: Principle of crushing comminution of gravel to stone chips and fine stone chips by means of crusher plates with lemniscate motion
Inventor: GRONAU DETLEF
IPC: B02C1/04
Filed: 1983-01-13
Abstract: The invention relates to the crushing comminution of gravel to stone chips and fine stone chips by means of two crusher plates, between which the material to be crushed (gravel) is comminuted by pressure. The crushing motion acts with a lemniscate curve on the material to be crushed and comminutes it between two wear plates arranged in a wedge shape with respect to each other. The material to be crushed, falling by its own weight, is pre-crushed in the filling region and is after-crushed or finish-crushed in the outlet region, owing to the lemniscate motion of the operating crusher plates. The principle permits a higher throughput of the material to be crushed than with hitherto known systems. The hitherto unavoidable caking together of segregated dust and stone chips with wet or moist material to be crushed is also largely prevented. This prevention of the caking together is a consequence of the lemniscate crusher plate motion, which effects a kind of forwarding of material to be crushed. The system can thus be fed with fully wet and moist material to be crushed. Immediate charging of the gravel after conveyance is possible. By the simple construction of the rectangular crusher plates, the principle operates with very cost-effective wear tools. These can be changed cheaply and with a marked saving in time. <IMAGE>
