Title: Height regulating hydraulic suspension - has rotating valve cylinder with radial control ducts and axial pressure valve
Inventor: LEINEWEBER GUENTER
IPC: B60G17/056
Filed: 1980-09-04
Abstract: The hydraulic suspension has a pressure line from a pump fed to a control valve. One output from the valve leads to the suspension element, via a pressure control valve, while a second outlet returns excess fluid to a low pressure sump. The two outlets are axially spaced and linked by an axial bore in a rotating valve element (3), with radial ducts to the inlet and dump connections. The setting of the suspension acts on the rotational setting of the valve element, which is sealed inside the bore by a series of captive sealing rings (10). The relative connection between the inlet and dump ports is controlled by a valve surface on the edge of the valve element, with no special precision valve seats required.

IPC: G21F9/30
Filed: 1980-12-05
Abstract: Liq. waste contg. boric acid is obtd. from the prim. cooling circuit of a nuclear power station. The waste is converted into B2O3 by the removal of water, and is then mixed with glass constituents with a low boron content and heated to form a borosilicate glass. The waste pref. also contains materials used to aid filtration, and prods. arising from fission, corrosion and activation. The glass constituents pref. consist of scrap, which is milled and mixed with the dried waste and then heated to 1000-1500 deg.C. to make a boron glass contg. up to 50% B2O3 and suitable for final storage. The liq. waste contains boric acid, and isotopes emitting beta and gamma rays, e.g. Co-60, Cs-134, Mn-54. The invention converts the waste into glass with a much smaller vol. than when cement is used to form a storable material.

Title: Continuous coating of metal parts or strip with molten solder - where stripper removes excess solder so exact thickness is left on strip
Inventor: HECK FRIEDRICH
IPC: C23C2/22
Filed: 1980-12-18
Abstract: Metal parts are coated on one or both sides with a solderable layer abtd. by immersing the parts in a bath of molten Sn or Sn-Pb alloy. While the solder coating is still molten, it is fed through or past one or more strippers so that a specific thickness of solder is left on the parts. The strippers use capillary forces to remove the surplus molten solder by suction. The strippers pref. consist of compressed wire mesh, steel wool, or bundles of wire, which are wet by the tin or Sn-Pb. The strippers are pref. partly immersed in a heated bath of Sn or Sn-Pb with a controlled height. An exact thickness of Sn or Sn-Pb is obtd. on parts without blocking any holes which may exist in the parts.
Patent DE-3048448-A1 (DE)
Inventor: HEGER FRIEDL
IPC: C08L61/28
Filed: 1980-12-22
Abstract: An improved process for substantially increasing the shelf-life of aqueous solutions of melamine-formaldehyde resins wherein the molar ratio of melamine to formaldehyde is from 1:1.7 to 1:3.5 by the addition of a stabilizing amount of urea after condensation, which process includes the steps of adjusting pH of the resin solution before and after the dissolution of the urea within certain narrow but easily controllable pH ranges. The properties of the resin solution can be further improved and the stabilizing effect of the addition of urea increased by adding a monohydric C1-C4 alkanol during condensation of the resin.

Title: Method and apparatus for the conical expansion of tubes or the like
Inventor: RETTENMAIER ALOIS ING GRAD
IPC: B21D51/36
Filed: 1981-02-03
Abstract: The invention relates to a method and an apparatus for the conical expansion of tubes. In order to be able to stack empty tubes in a space-saving manner in bar form for transportation, they are expanded conically at their open ends so that they can be inserted into one another. As Figure 1 shows, expansion is effected by centrifugal force due to the rotation of a shaft (1), at the forward end of which bars (2) cut out in segments from a tubular piece and over which the tube is pushed are pivotably attached. When the shaft (1) is rotated, the free ends of the bars (2), which are held together by a flexible ring (3), swing outwards and thereby expand the tube. <IMAGE>

Title: Process for producing solderable coatings
Inventor: STOEGER WOLFGANG DIPL CHEM DR
IPC: H05K1/09
Filed: 1981-02-06
Abstract: The invention relates to a process for producing solderable coatings on the surface of a substrate by depositing a first coating consisting of aluminium from an aluminium compound dissolved in an aprotic solvent, a second coating consisting of nickel, and a final third coating consisting of a soft-solderable noble metal. According to the invention, firmly adhering, solderable coatings are achieved in a more economical manner, compared to the prior art, by the first coating being deposited, rinsed and dried in an inert atmosphere, by the first coating then being tempered in vacuo or in an inert atmosphere, by the surface layer of the first coating being cleaned and ablated by etching, followed by immediate application of the second coating and finally the third coating, all the coatings being optionally deposited in an electroless manner or by electroplating.

Title: Cable supporting system
Inventor: KRAUSE GERHARD DR ING
IPC: H02G3/04
Filed: 1981-02-27
Abstract: The invention relates to a cable supporting system, which is loaded statically and dynamically (in steady state and transiently) for nuclear power stations or the like, having a line guide which is formed by struts which are mounted on the structural body at supporting intervals defined by the line fields and have horizontal cantilever arms which are intended to accommodate cable racks. In this case, it is intended to solve the problem of conforming with the safety requirements, which must also be satisfied in the event of a considerable stress such as an earthquake or aircraft crash, with simple and material-saving installation, possibly also in retrospect. This is achieved by means of a special support for the line guide and possibly in conjunction with decoupling of individual line part sections from the rest of the line guide. <IMAGE>

Title: Device for regulating and controlling the temperature of heating installations
Inventor: ZIEGENBEIN WILHELM DR ING
IPC: G05D23/32
Filed: 1981-05-13
Abstract: Conventional regulators are used simultaneously for controlling, for example reducing, the temperature. To this end, a thermal or mechanical intervention takes place in the regulator. The heating can be carried out by a special heating element or the regulator housing can be designed as a heating element (conducting plastics). In the event of mechanical intervention in the regulator, there can for example be a separation between regulator drive and valve. Important features which are necessary for trouble-free working are indicated. Thus, arrangements are indicated for forming the heating elements. Of greatest significance for the life of the regulator is the adjustment of the thermal influence. Various mechanical embodiments have also been indicated. Especially advantageous also is the control from a central unit. Calibratable arrangements have been indicated. From a central unit, it is possible to adjust the temperature of individual rooms without acknowledgement.
