Title: Furnace installation for straw or similar material
Inventor: SIMONIS JUERGEN
IPC: F23G7/10
Filed: 1982-12-22
Abstract: In a furnace installation for straw or similar material, a fuel strand (33) made of compressed short straw is inserted into a cylindrical combustion chamber (2) and combusted. The low-temperature carbonisation gases arising during the combustion are forced with combustion air into two oppositely symmetrical swirl movements (23, 24) which flow as burning turbulent flows in the longitudinal direction of the combustion chamber close above a glowing-fire bed (34). The swirl movements (23, 24) are produced by a baffle plate (18) below the glowing-fire bed (34) which completely overlaps air-supply openings (17) running in the longitudinal direction of the combustion chamber so that the combustion air flows out laterally from a gap space (20) between baffle plate (18) and combustion chamber bottom (10). As a result, there is formed between the glowing-fire bed (34) projecting beyond the baffle plate (18) laterally and the combustion chamber bottom (10) an air layer which makes the glowing-fire bed (34) slide in the manner of a fluidised bed. In the upper combustion chamber region, the air flows (21, 22) meet one another frontally and are forced into the swirl movements (23, 24). Both baffle plate (18) and inner casing (8) are designed to be easily removable. <IMAGE>

Title: Method for increasing the ability to concentrate and device for carrying out the method
Inventor: FLAIG OSKAR
IPC: A61M21/00
Filed: 1983-04-09
Abstract: A method for increasing the ability to concentrate and device for carrying out the method are based on the avoidance of a stress-related increase in the heart rate or on bringing the heart rate back to the rhythm of emotionally balanced situations by acoustically transmitting an imitation (14) of the heartbeat rhythm corresponding to a low signal sequence frequency. For this purpose, a signal emitter (9) and at least one electroacoustic transducer (10) are expediently built into the earphones (2) of a hearing protection device (1), such as is usually used for health reasons in noisy surroundings as an acoustic screening from the environment. The electroacoustic transducer (10) can be periodically driven by direct current and thus from an instable multivibrator (18) with a very unsymmetrical pulse duty factor, the beginning and the end of a direct current pulse in each case triggering a cracking noise similar to a double heart beat pulse (15). <IMAGE>

Patent DE-3431008-A1 (DE)
IPC: E04C5/03
Filed: 1984-08-23
Abstract: To produce threaded steel tension members, steel is used with a C-content of 0.50 to 0.80%, preferably 0.75%, a Si-content of 0.20 to 0.50%, preferably 0.25%, and a Mn content of 0.30 to 0.80%, preferably 0.60%. Exiting from the rolling heat at the outlet side of the finishing stand after hot rolling, the tension member or rod is subjected to surface quenching by a cooling medium, preferably water, so that the steel in a rim zone R1 is transformed immediately and completely into martensite, while the heat content remaining in the core zone K1 does not effect a tempering of the martensite rim zone during the subsequent cooling beyond the range of the intermediate stage. Steel tension members of this type have a high ductility and toughness at a high yield limit and high strength, they are corrosion-resistant to a great degree and have a wear resistant surface which makes them particularly suitable for threaded tension rods in which the threads are produced either by a cold forming operation or hot rolled ribs.
