Title: Fluidised bed brown coal and slurry drying - is carried out with recirculated, cleaned exhaust steam with condenser operated at specified temp. and pressure conditions
Inventor: WOLF BODO DR ING
IPC: F26B3/084
Filed: 1991-10-17
Abstract: Moist substances are dried above a fluidised bed, the vapour extracted being passed through a dust extractor (4) connected to an indirectly cooled condenser (3), and returned by a cooling fan (6) for recirculation in the fluidised bed (1). The condenser is operated at a temperature which is between one and 50 Kelvin e.g. 10 Kelvin above atmospheric temp. Drying in the indirectly heated fluidised bed is carried out above the bed at a vapour pressure between the dryer and condenser which is higher than vapour pressure in the condenser. USE/ADVANTAGE - For brown coal with a 70 percent water content and slurries with between 2 and 98 percent solid content. Efficiency is improved by use of recirculated steam at specified pressure conditions.

Inventor: BOERGER GEORG
IPC: A47J43/08
Filed: 1992-05-11
Abstract: In a multi-purpose food processor having at least a first (50) and a second (28) output shaft, which output shafts are driven by an electric motor at different speeds and are mounted concentrically relative to one another in their housing (3), the first coupling (18) can be connected to a first counter-coupling (42) and the second coupling (14) can be connected to a second counter-coupling (33). Furthermore, the first counter-coupling (42) is arranged on the outside of the bottom (53) of a first operating container (4), and the second counter-coupling (33) is arranged on the outside of the bottom (54) of a second operating container (52). In accordance with the type of processing, different operating tools (13, 47) can be inserted in the respective operating container (4, 52) for processing food, which operating tools are driven via the respective counter-coupling (42, 33) in the operating container (4, 52). Mounted at the upper end of the output shafts (50, 28) projecting from the housing (2) of the multi-purpose food processor are in each case a disc-shaped first ring (21) and second ring (25) which extend outwards and on which the toothing (22 and 29 respectively) of the relevant coupling (18, 19) is formed in each case. The rings (21, 25) lie concentrically one above the other in respect of the output shafts (50, 28) and have different diameters, the lower ring (25) located nearer to the housing (3) having the larger diameter and the lower speed. As a result, large torques can be transmitted at the second coupling (19) at a low speed and smaller torques can be transmitted at the first coupling (18) at a higher speed. The arrangement leads to a low constructional height with particularly smooth running. <IMAGE>

Title: Indigo dyeing of cotton yarn chain - involves adding wetting agent to at least first of several dye immersion troughs
Inventor: WROBLOWSKI HANS GERHARD
IPC: D06P1/22
Filed: 1992-12-09
Abstract: A process is for indigo dyeing a cotton yarn chain and entails using a wetting agent, which is added to the dyestuff of at least the first dye immersion trough. The dye bath of the trough with the wetting agent is circulated individually with a subsequent addition of dye and/or chemicals in accordance with the level and material exchange. The ratio of wetting agent to the dyestuff in the trough is set at the minimum amount of dye required for dyeing fast the material. Pref. wetting agent is also added to the second immersion trough - the amount is pref. relatively smaller than in the first trough. Less wetting agent is added to the successive troughs (in the direction of the chain transport) from trough-to-trough either singly or in groups of troughs. ADVANTAGE - The process ensures that the dye layers are applied evenly and reproducibly thinly in the successive troughs and can be oxidised virtually completely.

Title: Dimmable display device which has a constant colour location
Inventor: KNOLL PETER PROF DR ING
IPC: B60Q3/04
Filed: 1993-02-25
Abstract: For compensating a shift in colour when dimming incandescent lamps or halogen lamps as background illumination for a display device, it is proposed to arrange in the illumination device blue lamps in addition to the white lamps. As a result, the colour location of the white light which is shifted into the red part of the spectrum during dimming is compensated. When using the illumination device as background illumination in particular for a colour display this advantageously results in particular in an improved contrast for the blue colour. It is furthermore achieved by the arrangement according to the invention that the display has a very good contrast over a very large dimming range (Figure 2). <IMAGE>

Title: Valve arrangement for an antilock brake device
Inventor: ENGFER ORTWIN
IPC: B60T8/36
Filed: 1993-04-16
Abstract: A valve arrangement (6) which has two single valves (16/17, 19/20) is proposed for an antilock brake device. The first single valve (16/17), intended to control brake pressure increases in antilock operation, is closed at zero electric current. The second single valve (19/20) is open at zero electric current and can be kept closed by the flow of pressure medium and by the pressure gradient.

The antilock brake device with the valve arrangement (6) is intended for motor vehicles, especially for passenger motor vehicles. <IMAGE>
