Patent DE-2747038-A1 (DE)
Title: High-temp. gas-cooled reactor core of graphite blocks - contg. fuel elements of varying form causing gas channel outlet throttling
Inventor: WIESER RUDOLF DIPL ING DR
IPC: G21C3/30
Filed: 1977-10-20
Abstract: Core is composed of a number of fuel element units, each consisting of a prismatic graphite block of polygonal, esp. hexagonal cross-section, contg. vertical chambers in which numerous fuel elements are stacked and traversed by the coolant gas. The coolant gas passages are substantially parallel to the axis of the graphite block. The fuel elements in the fuel element units basically are of differing geometrical form and/or differing main dimensions, the fuel elements which cause a larger pressure drop in the coolant gas being located towards the outlet end of the hot coolant gas passages. Used in particular for a helium-cooled reactor. For a given permissible maximum temp. at the centre of the fuel elements, the gas outlet temp. can be increased without the total pressure drop across the core rising. The elements towards the outlet end of each chamber are smaller in size than the remainder, thus increasing the pressure gradient in this region and increasing the heat transfer at the surfaces of these smaller elements. This enables a higher gas outlet temp. to be used.
Patent DE-2749416-A1 (DE)
Title: Chloro-anthraquinone prepn. by chlorination of nitro-anthraquinone - in the molten state, providing prod. in high yield useful as dye intermediate
Inventor: SEIDLER HELMUT DIPL CHEM DR
IPC: C07C50/24
Filed: 1977-11-04
Abstract: The prepn. of chloroanthraquinones involves the passage of Cl2 into molten mono- and/or di-nitroanthraquinones, at 160-280 degrees C. The chlorination appts. can be a bubble column in >=1 stage, or a container equipped with a stirring system. The process can be continuous or discontinuous. The chloroanthraquinones formed in the molten state are then removed from the appts. The chloroanthraquinones are used in the prodn. of vat dyes, or dyes for wool. Compared with previous processes, this process does not require the use of a diluent; it gives high yields of chloroanthraquinones and to a certain extent improves their degree of purity.
Patent DE-2757271-A1 (DE)
Title: Recovery of metal from effluent in electrolytic process - with mechanical sepn. of metal from cathode
Inventor: KAMMEL ROLAND PROF DR ING DR
IPC: C02F1/42
Filed: 1977-12-22
Abstract: Metal present in the effluent from a process such as a galvanising bath is recovered electrolytically. The effluent is fed into vessel containing rotating cathodes in the form of rods mounted in a holder driven by a motor. The anodes consist of plates close to but outside the cathodes and a central cylinder. The rods fit at their ends in channels in the holder and are free to roll around the channel. The latter is partitioned which limits the travel of the rods relative to the holders. In each segment so formed, there is a void to allow the rods to move. As the rods move through the upper or lower central position, they fall through the void and are stopped suddenly against the partition or the adjoining rod. This motion shakes free the deposited metal which then falls to the bottom of the vessel. The outlet stream can be taken through a central perforated pipe via an annular basket filled with electrically conducting particles. The metal particles are prevented from forming a deposit on the conical floor of the vessel by two rotating arms which direct jets of electrolyte at the floor towards the centre. The particles then fall through the central outlet into a collecting vessel or recycling process. Because of the continuous agitation of the electrolyte and the close proximity of the cathodes and anodes, a virtually total recovery of the metal is achieved with very loq energy consumption. Furthermore, since the cathodes are continually cleaned of deposited metal, there is no need to change them and a continuous process is ensured.

Title: Cigarette storage equipment - has intermediate conveyor from distribution zone at receiver unit level to higher level hopper
Inventor: GRASSE HANS-JOCHEN
IPC: A24C5/35
Filed: 1978-01-27
Abstract: The storage equipment is for cigarettes etc. having a conveyor delivering them in a multi-layer stream, and a channel discharging them to a receiver unit likewise in a multilayer stream. When inflow exceeds outflow the cigarettes pass into a hopper where they are stacked being discharged from it when outflow exceeds inflow. An intermediate conveyor between the feed conveyor and the hopper also transfers them from hopper to channel and the height of the stack on the intermediate conveyor is less than in the hopper. The intermediate conveyor (352) leads from the distribution zone (V22) at the level of the receiver unit (P) to a hopper (353) mounted at a higher level.

Title: Coloured candle coiled into differently coloured layers - by manipulating laminated block to which ornamental granules are added
Inventor: KEMPTER HARTMUT
IPC: C11C5/02
Filed: 1978-02-11
Abstract: Highly decorative coloured effects can be produced on candles of wax, paraffin or stearine, in a series of steps commencing with the casting of a block formed by wax layers of different colours. The block is only cooled to 295 - 328 K and is maintained at this temp. until required for processing. The heated block is folded together and stretched at one side whilst being compressed at the other into a partly spherical lump. Cuts are then made down the sides and across the bottom to expose the layers and with heating maintained the block is twisted into a pear shape; twisting being continued until a head pulls off. The block is finally moulded into a cylinder, barrel shape or sphere and drilled for the wick.
