Abstract: 466,234. Rolling tubes. DEMAG AKT.- GES. April 24, 1936, No. 11699. Convention date, Feb. 25. [Class 83 (iv)] A set of universal rolls 1, 2, 3, 4, are arranged with the minimum spacing between the sets to shorten the left-over thicker end of the rolled tube by eliminating the usual common drive for each set and driving the individual rolls of each set from the corresponding roll of the previous set with the required gear ratio to give the required increase in peripheral speed, thus allowing the individual sets of rolls, (each set conveniently mounted in side plates 5, 6, Fig. 5), to be placed close together in the frame 14-27 when staggered with respect to each other. For example one of a number of driving shafts 26 drives through bevel gears 22, 23 the shaft 16 coupled to one roll 3 while the gear 17 on that shaft 16 coupled through an intermediate wheel 25 drives the gear 18 on the next shaft 16 so driving the roll of the next set at a higher speed. The other rolls are driven through the other shafts 26. The top 27 of the mill frame 27 can be pivoted up to allow changing of the roll sets as one unit, the shafts 26 having detachable couplings to allow of them moving too. The pairs of the individual rolls can be adjusted by screw 12 whereby the roll housings 9 can be moved about their pivots 10. Instead of gearing 17, 18 the rolls may have independent electric motor drive.

Abstract: 794,914. Rotary engines. KLORMANN, H. April 25, 1955 [April 24, 1954], No. 11820/55. Class 110 (2). One or more vanes 3 on a rotor 2 rotate in an annular chamber 1 of a motor and co-operate with one or more apertures 5<SP>1</SP> in a rotary abutment which is formed as a skirt 5 on a rotary valve 6 geared to the rotor 2 and having one or more inlet or outlet ports 9 with control means for adjusting the size of the ports 9. The rotary valve 6 is mounted in an overhung manner at its upper end within a housing 7, working fluid passing through a passage 11, through the arcuate port 9 in base plate 10 of the valve into the working chamber 1. A control member 13 comprises a disc with an arcuate port 15, the member 13 being rotatable relative to the base plate 10 so that the effective area of the port 16 can be regulated, as in Fig. 2, by the port 15. The member 13 may be regulated in accordance with the speed of the motor by a weight 17 tending to move outwards in a guide space 20 under the action of centrifugal force and so turning the member 13 relative to the base plate 10 through a rack 18 (attached to the weight 17) and a pinion 19, against the action of a spiral spring 21, a screw 31 limiting the outward movement of the weight 17. The loading on the spring 21 is adjustable as is the clearance of the member 13 above the base plate 10. The position of the weight 17 may be influenced by introducing the pressure of the working fluid to the space 20. In an embodiment, Fig. 10, the member 13 is adjusted arbitrarily by the pressure of fluid 37 acting on a piston 34 which is connected to the member 13 through a screw thread 33. An outlet passage 48, Fig. 5, from the working chamber 1 may be controlled by a groove 47 in the skirt of the rotary valve, or the skirt may be hollow and contain fluid passages. To aid starting the rotary valve 6 may have vanes 43 in the passage 11 by which the working fluid tends to rotate the valve 6, or the base plate 10 may have an additional inlet port 40, Fig. 3, which is open when the motor is stationary but is closed under the action of centrifugal force moving a shutter 41 outwards against the action of springs 42. The fluid feed may be controlled by a centrifugally operated throttle valve. The skirt 5 of the valve 6 is sealed relative to its housing by carbon or the like rods 50.
