Title: Organic contaminant removal from air - using bio-filter followed by filter stage or second bio-filter
Inventor: SOMMER WERNER DR ING
IPC: B01D53/85
Filed: 1992-09-05
Abstract: In the purificn. of air contaminated with hydrocarbon cpds. and/or odours by passing the collected air through a biofilter. The biofilter has a size providing only partial decomposition of contaminants. The air leaving the biofilter is collected as a stream for complete decomposition of contaminants either by passage through a further correspondingly sized filter stage in the form of an adsorption or oxidn. stage or by combining with a second contaminated air stream passed through a second biofilter. The obtd. clean air is released to the atmos. Two air streams are pref. combined by combining the collected air stream from a biofilter, through which a small contaminated air stream passes, with either a large contaminated air stream to be passed through another biofilter, when its contaminant concn. is greater than that of the outlet air stream of this other biofilter, or the collected outlet air stream of this other biofilter, when its contaminant concn. is less than that of the outlet air stream of this other biofilter. USE/ADVANTAGE - The process is useful for treating air from solvent use, foundries, agriculture and agricultural product processing. Air of the requisite purity is produced at relatively low cost

Patent DE-4305150-A1 (DE)
Title: Displacement-compensating load sensor
Inventor: LAUNHARDT GEORG
IPC: F16L3/20
Filed: 1993-02-19
Abstract: The load sensor is used for the stationary sensing of uniform loads which are moved by external influences such as, for example, expansion through temperature change or controlled level changes for height compensation at processing machines and transport equipment. The problem of the invention consists in creating a load sensor with force-compensating curve guidance of a spring, which load sensor has small dimensions and a low weight, a large load-dependent adjusting range as well as low friction losses and thus high functional reliability. According to the invention, the problem is solved by virtue of the fact that a spring (3) located in the load-sensor housing (2) is loaded via a balance-beam-like stirrup (10) and by means of guide-curve parts (5), circular-segment parts (7) and lever rails (6), and supporting elements (8) arranged in pairs in mirror image relative to the spring (3), the sliding piece (4) conveniently being designed as a roller spindle with several rollers. The advantages of the load sensor according to the invention consist in the fact that small dimensions of the load sensor, in particular in overall height, are realised by the conversion of the linear load displacement into a rotary movement by means of the circular-segment part as well as by the action of force, defined by means of the curved path, of the spring on the lever rail. The symmetrical design of the load sensor according to the invention, as a result of a favourable load distribution, also permits a dead-weight reduction of about 50% as against comparable ...

Abstract: PCT No. PCT/DE94/00310 Sec. 371 Date Feb. 16, 1996 Sec. 102(e) Date Feb. 16, 1996 PCT Filed Mar. 18, 1994 PCT Pub. No. WO94/21576 PCT Pub. Date Sep. 29, 1994The invention concerns a high-grade, long-duration, organic fertilizer and a method of manufacturing it by the oxidative ammonolysis of industrial lignin. The fertilizer contains nitrogen in the form of ammonium compounds, normally hydrolyzable amides and more strongly bound organic nitrogen. The proportion of more strongly bound organic nitrogen is 55 to 85%, preferably 65 to 80%, relative to the total nitrogen content of the fertilizer. The manufacturing process uses industrial lignin precipitated under alkaline conditions from alkaline waste liquors, extracts or solutions. Preliminary tests have confirmed that this process gives a natural-like, high-grade, long-duration fertilizer similar to humus in character and with surprisingly good environmental compatibility.

Title: Device for regulating the outflow of a tapping ladle in steel production
Inventor: STILKERIEG BERTHOLD
IPC: B22D41/46
Filed: 1993-05-06
Abstract: A device consisting of a regulating plug insertable into the outflow hole serves for regulating the outflow or outflow behaviour of tapping ladles. This regulating plug has a cylindrical basic body consisting of a plastic fireproof material which is arranged between two mutually displaceable plates, in such a way that, during displacement, the fireproof mass is pressed against the inner wall of the outflow hole and to that extent closes the latter. Provided in the middle of the basic body is a funnel channel which adjoins the upper funnel-shaped pressure plate and which cuts through the entire basic body. A jigging device can be introduced through this funnel channel and be used for pressing. This always identical tube of the funnel channel accordingly guarantees an opening rate which is always identical, thus appreciably improving the mode of operation of such a tapping ladle or a regulating device. <IMAGE>

Title: Hydraulic brake system with a traction control device, particularly for motor vehicles
Inventor: SIEGEL HEINZ ING GRAD
IPC: B60T8/175
Filed: 1993-06-03
Abstract: The intention is to counteract the development of noise in the operation of a high-pressure pump producing brake pressure in a traction control device. In traction control mode, the high-pressure pump delivers, inter alia, via a valve which protects the high-pressure pump. Quantities of pressure medium flowing out through the valve at periodic intervals give rise to unpleasant noises especially at the brake master cylinder. Connected to the outlet of the valve is a pressure-medium accumulator (33) which, within a cylinder (44), has a movable accumulator piston (41) and a compression spring (49) acting against the accumulator piston (41). The capacity of the accumulator is at most as great as one stroke volume of the high-pressure pump (29), which can, for example, be designed as a single-acting reciprocating-piston pump. By taking up and releasing pressure medium, the pressure-medium accumulator (33) equalises the flow of pressure medium from the valve (24b) to the brake master cylinder (11). As a result, fewer pressure pulsations and less noise arise at the brake master cylinder (11). The hydraulic brake system (10) is suitable, in particular, for motor vehicles. <IMAGE>
