Title: Anaerobic digestion pit for liq manures - with addn of cellulose wastes for methane prodn
IPC: C12M1/107
Filed: 1974-08-12
Abstract: Anaerobic digester, for the treatment of biodegradable matls., consists of a pit in which the organic and cellulosic matls., such as liq. manure from stables and piggeries together with paper, garbage and straw are deposited. The pit has an inclined base so that the wastes can be handled by an ordinary tractor fitted with a fork or shovel. The liq. manure is sprinkled over the cellulosic matter by the pump whilst air is injected by the blower, which assists the acid fermentation; the temp. rises to 80 degrees C and the heat is distributed by the circulation of the liq. manure. When the acid fermentation is complete, the pit is covered with a blank, pliable polymer cover which is kept in place by an elastic cord fixed to a hook inside the hydraulic joint which forms a water seal. The cover is impervious to methane which is produced by the anaerobic fermentation. The CO2 produced is fixed by the injection of ammonia to form ammonium carbonate and an improved final manure. The prodn. of methane by anaerobic digestion is assured by the addn. at the purificn. station of the cellulosic matter; there is no limit to the amt. of polluted matl. mixed with it.

Title: Frequency synthesiser for two inputs - forms sine and cosine signal from each input before integrating
IPC: H03B21/00
Filed: 1974-10-17
Abstract: The circuit is particularly applicable to equipment used for determination of the characteristics of various media, the two outputs being some function of information carrying input signals. The two outputs generated are intended to avoid the phenomena of pulling of one output by the other. Typically two input signals are fed to an oscillator (14) and sine/cosine generator (11) and to a complementary voltage generator and an oscillator. The resulting pairs of signals are passed to a synthesiser (13) producing products of separate signals from the pairs of signals and summing pairs of the products in set combinations to form two output signals, these signals being the sum and difference of the products.

Title: Rotor of axial flow steam turbine - has shroud ring round blade tips with slots to give tangential elasticity
Inventor: RIOLLET GILBERT
IPC: F01D5/22
Filed: 1976-12-23
Abstract: The rotor of an axial flow turbine has blades (2) projecting radially in a ring round the wheel. A shroud ring (1) runs round the outer tips of the blades and links them all together. It is made as a single annular ring. The shroud ring has slots (3, 4) cut, which are alternately axial slots (3) in the centre of the ring and pairs of diagonal slots (4) sloping towards the centre of the ring from the front and back of the ring. This construction of the ring provides stiffening to the blades with sufficient tangential elasticity to withstand the forces due to uneven steam loading. This is liable to arise on the inlet row of a nozzle controlled turbine.
