Title: Retaining-wall element
Inventor: HAEUSSLER WILHELM DIPL ING DIP
IPC: E02D29/02
Filed: 1981-09-16
Abstract: A retaining-wall element of thin-walled reinforced concrete consists of an upright leg (12) and a horizontal leg (14) and a centre stiffening rib (16) connecting these two legs. On both sides of the reinforcing ribs, drain plates (22) slotted on the inside are mounted on the upright leg (12), and located in the bottom corner area of the rib (16) is a hole (30) into which a drain pipe (32) can be pushed which is provided with circumferential openings and extends approximately over the width of the retaining-wall element (10). The retaining-wall element (10) can be completely prefabricated in the precasting plant. Several retaining-wall elements are placed next to one another on site in order to form a retaining wall which no longer requires any gravel backfilling, since collecting water is directed downwards into the drain plates (22) and between the drain plates (22) and the upright leg (12). This water passes into the pipe (32) and escapes downwards through widened edge joints in the horizontal leg (14). <IMAGE>

Title: Process for the isolation of crystalline 1,3-cyclohexanedione
Inventor: LITTERER HEINZ DR
IPC: C07C45/83
Filed: 1982-10-04
Abstract: The invention relates to a process for the isolation of crystalline 1,3-cyclohexanedione from the crude product formed in catalytic gas-phase cyclisation of 5-oxohexanoic acid. This is done by heating the crude product after condensation and then mixing, if appropriate after cooling, the crude crystals obtained with an auxiliary component comprising at least one compound from the group comprising cyclic hydrocarbons, chlorinated aliphatic hydrocarbons and monoethers, then distilling the mixture comprising crude crystals and auxiliary component under atmospheric or reduced pressure until the water of reaction has been removed and the residual content of auxiliary component in the remaining concentrate has reached a certain value and filtering off the crystalline 1,3-cyclohexanedione precipitated after this treatment. It is also possible to distil off the auxiliary component added virtually completely from the 1,3-cyclohexanedione. In this case, one, either the same or a different, compound or compound mixture mentioned as auxiliary components must then be added again to the remaining concentrate which is interspersed with crystals, so that the 1,3-cyclohexanedione separates out as completely as possible as crystals and a crystalline paste which can be filtered is formed.

Title: Self-sufficient plant for hot water and heating water for a household
Inventor: ULBRICH THOMAS
IPC: F24D11/00
Filed: 1983-02-09
Abstract: The self-sufficient supply of hot water and heat for a household operates according to the following principle:  hot water collectors are used in the usual manner. In addition, solar cells are to supplement this hot water circulation. At colder external temperatures, the hot water collectors would not alone be sufficient to bring tap water and heating water to the desired temperature. This problem is solved by means of the solar cells, the energy produced by them being exclusively used to decompose water into hydrogen and oxygen (only as a byproduct). The hydrogen thus produced, particularly in summer, can be compressed and stored in pressurised containers. As needed, i.e. when the desired temperature is no longer reached in the hot water circuit, an internal combustion engine with heat exchangers and a generator is driven by the hydrogen. The current produced by the generator is used to bring the tap and heating water to the required temperature by means of electric heating elements. The hot water circulation can thus always be fully maintained and the household can be supplied with current, as long as the generator runs, independently of the public current supply.

Title: Dumb-bell, especially a single-handed dumb-bell
Inventor: SCHNELL JOSEF
IPC: A63B21/072
Filed: 1983-06-30
Abstract: The invention relates to a dumb-bell, especially a single-handed dumb-bell, which bears interchangeable discs at the ends of an axle-like rod offering central gripping facilities, the discs being releasably secured in their position. Such a dumb-bell is to be improved in that a sufficient positional securing is achieved without projecting axle ends, and in addition there is no cause to fear damage to the set-down surfaces or floors. This is achieved in that the ends of the rod (cf. 2) make the transition into pot-like structures (3, 4) of identical axis whose internal width is slightly greater than the diameter of the equally large interchangeable discs (8) to be inserted and the positional securing of the inserted discs (8) is achieved on both sides by an axial lock (e.g. 12, 13) which acts from outside to in, that is to say towards the handle part (5), and lies immediately in front of the discs (8). <IMAGE>
