The invention concerns a biological sewage-treatment method in which gas is first passed through a mixture of sludge and sewage in an activation stage (2) and the activated sludge then separated from the treated sewage by flotation (5). The method is characterized in that the concentration of the sludge in the activation stage is >/= 6 g/l and that flotation is achieved by pressure release.

The appts. to splice multifilament yarns has a splicing chamber (1) with yarn clamps (9,9') and a spring (15,15') for each clamp (9,9'). The yarn clamps (9,9') have an adjustable clamping force. Each yarn clamp (9,9') has three clamping segments (11-13;11'-13'). A yarn (5,5') is inserted between two clamping segments (11-13;11'-13'), and the spring (15,15') applies a clamping force to the segment...

A traction control system and method of a four-wheel drive vehicle comprises an engine control apparatus, a brake drive apparatus for automatically and independently applying brake to each of four wheels, wheel speed detecting means, vehicle speed detecting means, steering angle detecting means, yaw rate detecting means, target yaw rate calculating means, yaw rate deviation calculating means, slip...

The assembly to deliver wound bobbins from a spinner, and especially an open-end spinner, has a main conveyor to carry wound bobbins along the spinning machine for transfer to an auxiliary conveyor at its end. The auxiliary conveyor (3) has a height adjustment setting. A magazine for the bobbins, with stacked holding levels, is at both sides of the auxiliary conveyor (3) for the bobbins (2). A mec...

The valve is comprised of a strip (1) on which are welded two coplanar strips (3, 4) separated by an opening (5). In order to fabricate the valve, a web (11) is used on which are welded two bands (12, 13), separated by a gap (5). The resulting valve (16) is welded onto a sheet (17) which is part of the inflatable body, is provided with an orifice (19) in registration with the opening (5) of the va...

A lamp has several pivoting battens (5) used as a screen. The battens are pivoted eccentrically relative to their cross-section. In fact their shape is circular with a screening lip (6). They are parallel to each other and are spaced apart so that on adjustment they can touch or have a space between them. There is a handle to operate them. Several or all the battens have the same range of movemen...

The power train of the vehicle has a variable valve (23) in the exhaust duct to control the engine braking, and a retarder (13) between the gearbox/clutch and the wheels. Both braking systems are combined by the transmission control (31) with the overall braking effect divided between the two braking systems in a programmed manner depending on the change down mode. The rate at which the retarder i...

The intermediate storage unit (1), for full bobbins (2) on sleeves (10), holds a large number of bobbins taken from bobbin winders in a matrix layout. The unit has angled rails (3) where the bobbins (2) are laid with their sleeves (10) to roll along. Movable locks (4) are in the rolling paths of the bobbin sleeves (10) to hold the sleeves (10) in place so that, on a rolling path, the laid bobbin...

The control system for the automatic transmission monitors the engine torque and the input and output speeds of the transmission. The control generates a reduced value for the input speed and adjusts the torque reduction accordingly, to produce a smooth change in torque. The control system samples the transmission at preset intervals. The time period during which the torque reduction operates is d...

The yarn ballooning action, at a creel, is limited by gps. of paired moving rods (14a, 14b) where the yarns from one row of bobbins are drawn between the rods. The rods (14a, 14b) are given a sliding movement on a parallel plane with each other in relation to the row of bobbins, through a common operating mechanism (24a, 24b, 25a, 25b). Each rod slides on a movement plane about at right angles to ...
