Title: Process for removal of sulphate from alkali metal chloride brine
Inventor: BLUM KLAUS DR
IPC: C01D3/16
Filed: 1988-02-19
Abstract: To remove sulphate from alkali metal chloride brine, in particular also from alkali metal chloride brine from a refuse incineration plant or a coal-fired power station, preferably for use in chlorine/alkali electrolysis, solid calcium oxide is, in a first step, suspended and slaked in a sulphate-containing alkali metal chloride brine or in water with the introduction of high shear forces by means of stirring or pumping. In a stirred precipitation vessel, the calcium oxide slaking brine or calcium oxide suspension is brought into contact with one to two times its volume of alkali metal chloride brine, preferably with a substream of up to 40% of the amount of circulating brine of a chlorine/alkali electrolysis, at a pH of from 2 to 9, and the sulphate is precipitated as CaSO4.2H2O while stirring or pumping at a temperature from 20 to 90@C.

Title: Method and device for casting rings, bracelets and the like in a transparent plastic body
Inventor: FINAMORE BENIAMINO
IPC: B29C45/14
Filed: 1988-03-03
Abstract: The method described and the device provide for a ring (27) to be positioned between the two profiled depressions (3a, 4a) of two mould halves (3, 4) which are located on an injection-moulding machine. The positioning of the ring (27) takes place by means of support elements (14, 15) which run displaceably through the said mould halves (3, 4). The mould halves (3, 4) are moved close together so that the ring (27) is enclosed in a hollow space (5) described by the depressions (3a, 4a) into which the molten, transparent plastic material is cast.   As long as the plastic material has not yet completely hardened, the supporting elements (14, 15) controlled from outside the respective mould halves (3, 4) are removed from the ring which is now suspended in the plastic material. The plastic material contained in the hollow space (5) is then compressed and subsequently cooled until it hardens. A ring (27) is obtained which is cast in an annular plastic body (28) through which the profile of the ring (27) itself is visible. <IMAGE>

Title: Manhole cover for manholes lying in traffic areas
Inventor: FLOSS HILMAR
IPC: E02D29/14
Filed: 1988-06-25
Abstract: The invention relates to a manhole cover (6) for manholes (4) lying in traffic areas, having a manhole frame (1) which is arranged roughly axially in alignment above a manhole (4) and has on its outside at least one flange (3) or suchlike anchoring for engaging in the surrounding road surfacing (5) or the like. According to the invention, the manhole frame (1) is here arranged above the manhole (4) essentially without supports or connections. Such a manhole frame (1) forms a "floating" manhole cover (6) which follows at least slight settlement of the road surfacing (5) and can neither sit on nor strike the top area of the manhole (4). A manhole cover (6) loosened, for example, by high traffic loading or under the action of frost can therefore cause hardly any damage, which is expensive to repair, to the top manhole area, as can otherwise result in previously known manhole frames due to the manhole frames hitting the manhole (4) (cf. Fig. 3). <IMAGE>

IPC: F16B25/10
Filed: 1988-08-22
Abstract: The manufacture of self-tapping screws 1, provided with a drill point 9 and an adjoining thread 7, in particular from high-grade steel is proposed in which the drill point 9 is formed on the shank 4 by pressure forming between two pressure jaws of a tool which are adjustable approximately transversely to the shank axis. Used for this is a blank with a length section of reduced diameter located at the free shank end. The drill point 9 with two rectilinearly running flutes, plane flanks and negative rake angles as well as large clearance angles is then pressed onto the length section of reduced diameter. At the same time, the front part of the free shank end is widened crown-like in certain areas over the reduced diameter. Finally, the thread 7 is rolled into the shank section 5 of larger diameter and in the process a minor diameter at least approximately equal to the diameter of the shank section reduced in diameter as well as an external diameter greater than the diametral size of the section widened crown-like are produced. <IMAGE>

Title: Method of redeveloping cleaning up contaminated sites (old landfill sites)
Inventor: HOLZER HORST
IPC: B09B1/00
Filed: 1989-03-16
Abstract: To clean up contaminated sites, a gallery is driven in the competent rock under the landfill. From this gallery, holes are drilled upwards parallel to the base at right angles to the gallery or landfill axis according to a certain grid. These holes are grouted with a prepared emulsion of cement, fly ash and water and the soil layers are injected with it. The free landfill flank is sealed off according to another method of the applicant (P 3642786.1 of 15.12.86). The landfill flanks are stabilised in the same way as the base but with perpendicular boreholes. The landfill body is then bored perpendicularly with boreholes and likewise grouted. This leads to the removal of the existing cavities and to the compaction of the landfill body. The method is especially efficient compared with hitherto known methods. In the process, there is no pollution of the environment through shifting of the waste body and there is no health risk. Likewise, enrichment of the waste with oxygen, which occurs during shifting of the waste, is completely prevented.
