Inventor: FURUMOTO HERBERT DR
IPC: F23N5/00
Filed: 1992-06-30

Pref. appts. includes means for measuring the mass of the waste liquor stream, firing temp. and content of gases, esp. 02, NOx, and CO in the flue gas and prim. sec. and tert. combustion air vol. and temp. regulators controlled by signals obtd. by comparing these values with ideal values.
Patent DE-4222922-A1 (DE)
Title: Loading control for pneumatic sprung double axle - has pressure sensors on main axle controlling diversion of excess load to secondary axle to maintain traction on main axle
Inventor: KOESTER ROLF DIPL ING
IPC: B60G17/052
Filed: 1992-07-11
Abstract: The pressure sensors (3) on the main axle (1) prevent overloading of that axle by diverting pneumatic pressure, from the pumped supply (8), to the secondary axle (4). The control valves (10) reduce the main axle loading back to the maximum, with the excess load taken by the secondary axle. If the total loading is below the main axle maximum level then the secondary axle is totally free, and can be lifted off the road. A three way valve (10) between the axles connects the axles, disconnects the axles, and in a third setting disconnects the axles while venting the secondary axle. One pressure sensor can operate on the whole system or each side of the vehicle can have a separate control. ADVANTAGE - Simple load distribution control which ensures maximum traction for main axle.

IPC: B03B5/52
Filed: 1992-10-15
Abstract: The invention relates to a drainage scoop wheel for recovering fine sand from the washing water of gravel washing installations. It is based on the object of reducing the quantity of clean water and waste water in gravel and sand processing and of at the same time improving the efficiency of the fine-sand recovery and the quality of the fine sand. According to the invention, this object is achieved in that channels (6) are arranged inside the scoop wheel tub (1), on the tub wall opposite the inlet (4) on both sides of the wheel (2), in that the channels (6) lead, at their upper end, via one or more passage opening(s) (17) in the tub wall, to one or more water collection reservoir(s) (8, 16) in such a manner that the same liquid level results in these water collection reservoirs (8, 16) as in the tub (1), the water collection reservoirs (8, 16) being connected to at least one suction pump (7) which pumps or pump the water flowing through the channels (6) out of the tub (1) as recycling water back into a gravel washing installation arranged upstream of the scoop wheel, and in that the channels (6) have intake openings (18) at their lower end, at a sufficient distance from the waste water layer (15). Seen from the intake openings (18), the channels (6) run obliquely upwards towards the side of the outlet (5). <IMAGE>

Title: Liq. treatment to form fine suspension or emulsion - e.g. in treatment of contaminated soil slurry or waste water
Inventor: JUENGLING HARRY
IPC: B09C1/02
Filed: 1992-12-08
Abstract: In a process for treating liq. such as an aq. slurry of contaminated soil and/or waste water by-prodn. of a fine suspension or emulsion, the liq. circulates from the bottom of an inner container to the bottom of an outer container and from the top of the outer container back to the top of the inner container. The novelty is that (a) the liq. is exposed to shear forces in the gap between a rotor, located in the inner container, and a stator formed by at least a section of the bottom and/or lower wall region of the inner container and (b) the liq. is forced by the rotor from the bottom of the inner container through stator openings into the bottom of the outer container. Also claimed is appts. for carrying out the above process. ADVANTAGE - A very fine, uniform suspension or emulsion is produced in a simple manner.
Patent DE-4300631-A1 (DE)
Inventor: SCHUELER PETER ING GRAD
IPC: F02M59/10
Filed: 1993-01-13
Abstract: A fuel injection pump includes a pump piston (9) reciprocated in a cylinder liner (1) by a cam drive (10). An axially displaceable annular slide (19) for controlling the fuel delivery is disposed in a suction recess (20) of the cylinder liner (1). Fuel is delivered from a working chamber (14) when piston passages (16, 18) are closed by the slide. In order to avoid an inadmissibly high pressure rise in the working chamber (14) in the event of an uncontrolled adjusting movement of the slide (19) in the direction of a retarded termination of delivery, the pressure in the working chamber is relieved when the piston is near top dead centre. To this end the piston (9) has a radial bore (61) permanently connected to the working chamber (14) and arranged to be opened by a control port (67, 69) permanently connected to the suction recess (20). Alternatively a radial bore in communication with the working chamber enters the suction recess (20) towards the end of the delivery stroke. <IMAGE>

Title: Apparatus suitable for absorption of fusion energy from ice cells or for absorbing artificial cold energy and feeding it into a heat-removing system (called energy absorber)
Inventor: GABLER MARTIN
IPC: H02B1/56
Filed: 1993-09-04
Abstract: There is proposed an apparatus which works on the principle of passive air-conditioning and, as required, is supplied with cold energy from the energy absorber according to the invention. The air-conditioning system serves to remove heat from rooms containing communications equipment, for electronic switchgear and automatic control equipment, as well as EDP equipment, which are subject to a critical limit temperature. Apparatuses of this type are not known. In comparison with known active air-conditioning installations, the apparatus according to the invention is distinguished in particular by a substantially lower energy requirement. Operation sequence of air-conditioning model R11 and R2 according to DIN 50019 part 3:   A) Exchange of the heat load to the surroundings via air cooler and air heater. B) Exchange of the heat load as in A, with additional feeding of cold energy from the energy absorber into the air-cooler flow. C) Conversion of the heat load into the energy absorber for delivery to the ice layer or to the evaporator of the refrigerating set. Dissipation of the condenser waste heat via air heater. D) Night-time charging of the melted ice layer by refrigerating set with simultaneous dissipation of the heat load as in A.   The size of the ice cells including energy absorber is governed by the heat load to be dissipated, approx. 95 watts energy from heat of fusion being reckoned with per litre of ice.
