Abstract: The assembly to cool rolled strip material in a rolling train, with at least two beams to spray across the direction of strip travel behind each other, has a sliding movement for the spray beams (26,27) across the line (20) of strip travel. Each beam has a sliding drive (12,12') with adjustable and preset sliding positions. Pref. the spray beams (26,27) slide in the same or opposite directions. Several spray beams (26,27) are assembled into groups (4,5) with a drive (12,12') for each group. The groups (4,5) of spray beams (26,27) are interlinked so that the beams in each of two groups alternate with each other. The spray tubes at one side of the spray beam have the same dia. and the same intervals, the same dia. but at unequal intervals, or different diameters at the same interval. The jet width at the outlet openings are constant or unequal. The side walls of the jet slits are adjustable to vary the jet gap width to the outlet opening. The sprays beams (26,27) are linked to the fixed supply channel (28) through valves (29) and tubes (30,31) which can take up the beam movements. The spray beams (26,27) are above and/or below the cooling roller conveyor (21). The plates to contain the spray extend over the edges of the roller conveyor (21), with drives to slide them against the direction (20) of strip movement, and the plates are rectangular with generally trapezoid recesses at least at the two long sides and across the roller conveyor (21), or the long sides can have a comb structure, and are above and/or below the roller conveyor (21). At least the shrouding plates above the roller conveyor (21) have vertical walls at their edges to form a trough, and they each have an outlet opening outside the roller conveyor (21) zone. A number of shrouding plates above the roller conveyor (21) are firmly bonded together by their ends matching the dimensions of the groups of spray beams (4,5), so that they move together from the sliding drive. At least three thermal senso.

Title: Igniting propellant powder at high temp. after coating - with partly burned pyrotechnic material forced through perforated disc
Inventor: ZIMMERMANN GERD DIPL ING
IPC: F42C19/08
Filed: 1990-12-08

Title: Paper web guide roller - has a soft mantle to transfer web from press section to the next stage without web fracture
Inventor: STERZ HELMUT
IPC: D21G9/00
Filed: 1991-05-17
Abstract: The web guide roller, to take the web from the press section of a papermaking machine for movement towards the next stage, has a soft roller mantle which is not resistant to radial distortion. The web guide roller is an inflatable tube roller, with a rotating axis and two mantle support discs to contain and hold the air tight and inflatable mantle. The roller can also be a rotating carrier body with an extremely soft mantle cladding with a thin outer layer, which is smooth, and an inner bulk layer to bond it to the carrier body. The thin outer layer is pref. of a polyurethane, or similar plastics material, with a ground outer surface. The inner bulk layer is a foamed plastics material. The guide roller is connected to a drive, to rotate at a higher speed than the press roller. The roller mantle can be shifted radially in relation to the roller axis to vary the gap between the guide roller and the press roller, or the roller bearings allow its position to be varied. The gap between the guide roller and the next roller in the line of web travel can also be varied. The position of the guide roller is set in a coarse proximity to a tangent at the press roller surface. The following roller is a fourdrinier guide roller, pref. as a suction roller, or it is a drying cylinder and the guide roller is in contact with it for the web transfer. ADVANTAGE - The roller transfers the paper web positively between stages of the papermaking machine, without the risk of web fracture and without imposing longitudinal stress on the web which could give an undesired stretch while it is still damp.

Title: Pressing powder into soil or slurry - using column-type pressing body which sucks water away leaving soil more rigid and firmer
Inventor: BOESINGER EUGEN DIPL ING
IPC: E02D3/12
Filed: 1991-11-11
Abstract: The method is for the stabilisation and/or displacement and/or decontamination of soft soil or slurry and involves dry powder being pressed into the subsoil pneumatically by lances (2). The flow capacity of the powder is increased by the addition of synthetic powder and/or electrical discharges. Additions cause the powder in conjunction with the ground water to harden and/or to become conductive.
