Title: Underground coal gasification waste heat recovery - by injecting water and extracting steam for district heating or power generation
Inventor: WENZEL WERNER PROF DR ING
IPC: E21B43/243
Filed: 1975-07-28
Abstract: Waste heat produced during an in-situ gasification of coal seams which has not been utilized for gasification is recovered by pumping water into the worked out areas, pref. through boreholes which have been laid off after they have been used for the gasification circuit. The steam produced is extracted through boreholes. The water is, in the case of inclined coal seams, introduced at the deepest point. If the gasification is carried out at high pressures (40 bar), the water is introduced at the same pressure. This produces steam of high pressure and quality. In the case of thinner coal seams, it may be the decisive factor in making underground gasification profitable.

Patent DE-2549587-A1 (DE)
Title: Failsafe antiskid brake control - with time dependent parallel switching of brakes on each axle if brake modulation takes too long
Inventor: SCHNAIBEL EBERHARD DIPL ING
IPC: B60T8/88
Filed: 1975-11-05
Abstract: The anti-skid brake control of each wheel is monitored by a control circuit which determines the time taken for the modulation to take effect. If this time delay is more than a set level then the brake instability can lead to skidding, or steering difficulties, especially on poor road surfaces. The control switches the brakes on each axle in parallel after the set time delay. The non blocked wheel brakes on the axle are switched to the modulated circuit after the time delay, unless the fail-safe interlock is cancelled. A second monitoring circuit monitors the effect of the parallel switching, and if this does not take place, unless cancelled, then a second fail-safe cancels the whole of the anti-blocking control and operates the brakes manually.

Title: Alginate-contg. foodstuffs - produced by water-swelling of soluble alginate in presence of cations forming poorly soluble alginate salts
Inventor: DAHLGREN STIG AAKE
IPC: A23L17/30
Filed: 1975-11-10
Abstract: Foodstuffs suitable for use as fodder, foods, food substitutes or food additives are produced using a water-soluble alginate by a process in which the alginate in powder form, opt. together with a nutrient substance (e.g. protein, albumin) is mixed with water while an acidifying agent and a cpd. which can release into the aq. soln. cations which form a poorly soluble salt with alginic acid are added, the swelling being terminated by the addition of a salt to the solution when the alginate granules have swollen to the desired size without reaching the gel state, so that the alginate granules (at least on their surface) have been converted by ion-exchange into a poorly soluble salt. The water-soluble alginate is pref. sodium or potassium alginate. The acidifying agent is pref. citric acid. The cations forming a poorly soluble alginate are pref. calcium ions. Method is useful for prodn. of food and feed products having a granular texture e.g. resembling fish roes or caviare). Since the hardness of th granules can be controlled within a wide range by variation of the process conditions, a wide range of natural food textures can be imitated.

Title: Building block for radiation-proof walls - has form necessitating only one block for square and circular structures
Inventor: HIRSCHEIDER ERICH
IPC: E04C1/39
Filed: 1977-01-04
Abstract: Thin wall giving protection against radiation are built up from blocks, the mantle surface of which is formed by flat and rectangular four-sided figures. One part of the mantle surface formed by quadrangles has a concave joining contour, whilst another part, similarly formed by quadrangles, has a convex jointing contour. These two contours are derived from the mantle surface of an equilateral prism. At the end of the concave contour, are provided reinforcing ribs which have, as their base surface, the quardrangles of the building block mantle surface. One side face of the ribs appertains to the concave jointing contour, whilst another side face borders on the quadrangle of the convex jointing contour. The fourth side face of the reinforcing rib corresponds in its dimensions to the quadrangles comprised in the concave and convex jointing contours. Where the side of the reinforcing rib boardering the quadrangle meets the fourth side face, the edge is chamfered. The number of quadrangles in the concave jointing contour is >=2 less than the number of rectangles in the convex jointing contour. Only one shape of building block is necessary. The blocks are formed from simple geometric figures. The surfaces are laid out so that the geometrical figures can be created parallel to each other. The blocks can be laid out ont only in a straight line, but can also be turned through an angle and remain radiation-proof.
