Title: Screwdown mechanisms for rolling mills
IPC: B21B37/60
Filed: 1961-09-18
Abstract: 952,941. Rolling. UNITED ENGINEERING & FOUNDRY CO. Sept. 18, 1961 [Sept. 19, 1960], No. 33345/61. Heading B3M. [Also in Division G3] The worm and worm-wheel driven screwdown of a rolling mill is driven, independently of the normal rotation of the worms, by an hydraulic piston and cylinder arrangement which moves a worm axially. The conventional drive to a screw 16 is from a motor 31 which drives through pinions 29 and 27, a worm 25, and a worm-wheel 23. The drive to the other screw 17 is similar, the two motors 31 and 32 being interconnected by a clutch 33. In operation, however, the pass is rapidly and accurately adjusted by an hydraulic pistoncylinder arrangement 43 in response to variations from a standard in the thickness of the rolled material, as measured by an X-ray gauge. In order to keep the piston of the arrangement 43 centrally positioned and therefore ready for movement in either direction, the worms are rotated by the motors 31 and 32, in response to a signal from a position transmitter 62, in coordination with their axial motion. The position transmitter is driven from a pinion 56 which co-operates with a rack 55, connected to the worms. On failure of either the electrical or hydraulic system the axial movement of the worms is locked, and control is purely from the motors 31 and 32. In a modification the worms may have helical splines at their ends so that axial motion gives rise to rotation and increases the speed of operation of the worms.

Abstract: 507,060. Kinematograph apparatus. STEWARD, A. W., and PARSEY, E. J. Dec. 3, 1937, No. 33532. [Class 97 (i)] Kinematograph pictures on a band having transversely extending slits, in an opaque portion of the band, and at the same pitch as the pictures, are exhibited by an apparatus comprising feeding; means for the band and a light source, light from the source being caused by the slits to traverse each picture in turn. Fig. 1 shows a construction in which light from a lamp 6 is caused by slits 5 between the pictures in the band 1, and by a mirror 7, to traverse successively each picture on the band when the band is fed by rotation of a handle 4. The strip of light moves faster than the band and in the same direction, and the illuminated picture is viewed through an eyepiece 8. In a modification, Fig. 2, the band is drawn from a spool 2, through a guide 13, 14 and over a roller 11, laterally-placed rollers 15, and a roller 16, by rotation of a handle on the spindle of a spool 3. Light from a lamp 6 between the rollers 15 is controlled by the slits, and by a mask 12, to illuminate the pictures as they pass beneath an eyepiece 8 ; the strip of light moves in a direction opposite to that the illuminated pictures. The rollers 15 and lamp 6 may be carried by a frame 19 movable on side plates 17 away from the mask 12 to facilitate threading. Slots 28 in the side plates and hook-shaped slots 30 in the frame 19 may house the spindle of spool 3; a a battery 23 may supply the lamp. The apparatus may be modified for projection, and the band may carry pictures on each side for alternative use.

Abstract: 834,951. Centrifugal pumps. FARE ARMATURFABRIK A.B. Oct. 28, 1957, No. 33607/57. Class 110 (1). [Also in Groups XIX and XXXV] In a centrifugal pump driven by a shortcircuited alternating-current motor disposed laterally of the pump housing, the motor rotor and the pump impeller being connected together for rotation on a stationary shaft, and the rotor being enclosed by a cylindrical shell which is clamped against the motor stator by means of the stationary shaft and has an outwardly-directed flange which is clamped between the stator and the pump housing, the impeller has a larger external diameter than the rotor and has its largest circumference close to the flange of the shell and radially outside the cylinder of the shell. The motor rotor 12 and the pump impeller 13 are secured to a bearing- sleeve 14 which is journalled on a stationary shaft 10. The shaft 10 is secured to a statorcarrying cap 4 by a nut 20, with a cylindrical shell 16 tightly clamped between the cap and a distance-ring 18 which abuts a shoulder on the shaft. A flange 15 at the other end of the shell 16 is tightly clamped against the pump housing 1 by the cap 4, which has a threaded engagement with the housing. The impeller 13 is of greater diameter than the rotor 12 and has its largest circumference close to the flange 15, so that centrifugal force prevents solid particles entrained in the pumped liquid from entering the clearance between the shell 16 and the rotor 12 and damaging the shell and rotor and possibly jamming the rotor. To ensure that pumped liquid can rise in the shell 16 to lubricate the shaft bearing, air collecting in the shell can be vented to atmosphere by way of passages 25 in the distance-ring 18 and a passage 21 in the shaft 10, a plug 22 being removed for this purpose. The plug 22 may be replaced by a cock. To permit inspection of the impeller 13, a lens (not shown) is recessed into the wall of the housing 1, and a similar lens is provided adjacent or diametrically opposite the viewing lens to permit a light to be shone into the pump.
