Abstract: The invention avoids the segregating action of component streams in dry mortar in transportable storage containers in which, at least in the lower emptying region, segregation-disrupting inserts provide vertically running flow channels of limited cross-section which hinder or prevent horizontal flows, resulting in the formation of heaps of debris, of individual mortar components.
Patent DE-3131959-A1 (DE)
Title: Process for producing a homogeneous mixture of finely divided hydrated lime and wet coal
Inventor: ZANDER HANS VON DIPL ING
IPC: C10L9/10
Filed: 1981-08-13
Abstract: To produce a homogeneous mixture from extremely finely divided hydrated lime and wet coal, ground burnt lime is mixed with the coal and the ratio of burnt lime to coal is adjusted in this case in such a way that the temperature increase caused as a result of the exothermic heat of reaction of the hydration does not exceed a permissible value favourable for the process of, e.g., 50 DEG C. Hitherto, the starting material which had to be used instead of the burnt lime was the more expensive and more difficult to handle hydrated lime.

Title: Process for treating waste waters from flue gas desulphurisation plants
Inventor: WEBER EKKEHARD PROF DR ING
IPC: B01D53/48
Filed: 1981-09-19
Abstract: In the flue gas desulphurisation by scrubbing the flue gas with circulating calcium oxide- or calcium hydroxide-containing scrubbing liquids, waste waters (effluents) are produced both in the drying of the resulting gypsum and in the excess scrubbing liquid. It is proposed not to discharge at least some of these scrubbing waters, but to bring them in contact with the flue gas or a part of the flue gas and thus to evaporate all or some of the waste waters. In this case, organic constituents, which are desired there, return via the flue gas into the scrubbing water circulation, while constituents undesirable there, in particular inorganic constituents, chiefly calcium chloride, remain as solids.

Patent DE-3202215-A1 (DE)
Title: Control element arrangement in units with fluid flowing through them
Inventor: EICKMANN KARL
IPC: F01B3/00
Filed: 1982-01-25
Abstract: The invention relates to a control element arrangement with axially displaceable bearing of the control element in a mount and at least one contact pressure chamber behind one part of the control element for pressing the control surface onto the sealing surface of a machine with fluid flowing through it. Such arrangements have proven successful for certain pressures and rotational speeds but is it now recognised that at high pressures and speeds known control elements have a tendency to twist in the direction of rotation and then jam as under a wedge action. This disadvantage, first recognised by the invention, is overcome by the invention in that the twisting and jamming of the control element is prevented by more precise calculation and design or by arresting to prevent twisting. The patent application shows examples of the new control element arrangement and precise methods for its calculation. <IMAGE>

Title: Tight coke-oven door
Inventor: STOG WILHELM DIPL ING
IPC: C10B25/06
Filed: 1982-11-10
Abstract: The sealing of the lateral openings of horizontal-chamber coking ovens is of particular importance both for operating and ergonomic reasons as well as for the protection of the environment. For this purpose, coke-oven doors are used which have a door body consisting essentially of the elastic sealing plate, the lock bolts and the lock hooks, as well as pressing elements. The lock bolts are arranged rigidly and serve as abutments for the pressing elements. They are connected to each other by a continuous metal sheet and can be locked and unlocked via a lift part, in which connection they can be simultaneously lifted and lowered via the metal sheet. During the locking and unlocking, they are guided and held in the claws of the support pieces which are connected to the pressing elements. They can also be developed at the same time as pressing elements. All in all, this ensures that, even in the case of rigidly arranged lock bolts, the locking and unlocking process can take place without the coke-oven door having to be raised and lowered as a whole. <IMAGE>

Title: Method and arrangement for generating two frequencies at a fixed ratio to one another
Inventor: SCHWAB GUENTHER DIPL PHYS DR
IPC: H03K23/66
Filed: 1982-12-07
Abstract: The invention relates to a method for generating two oscillations with frequencies which are in a fixed, preferably not integral-numbered, ratio from a reference frequency. For this purpose, a counter, which can be loaded with a freely selectable count, generates an overflow or interrupt signal which is used for generating the frequency signals. The counter is loaded via a preloading circuit in dependence on the position of a status flip flop, the position of which, in turn, depends on the in each case preceding interrupt signal. The method can be used particularly advantageously in single-chip microcomputers for forming two frequency series having frequencies which are in a fixed ratio to one another.
