Title: Rolling mills for rings and discs
IPC: B21H1/04
Filed: 1958-11-20
Abstract: 901,372. Rolling rings and discs. KENDALL, E. H. Nov. 20, 1958, No. 37333/58. Class 83 (4). In a mill for rolling metal rings, discs and the like, working stations 10, 11 12 are each provided with a pressure roll 16 and working rolls 13, 14, the working stations being moved radially outwards in synchronous manner so that accurate circularity is maintained during radial expansion of the blank 15 during rolling. At each station a carriage 19 is slidably mounted on rods 18 and is traversed by a rotatable threaded shaft such as the shaft 61, all the shafts being geared together. The horizontallyspaced pressure rolls 16 are carried so as to be vertically adjustable on a yoke 26 attached to an hydraulically operated carrier 24 slidable in a guide member 25 fixed to the carriage 19. The upper working roll 13 is clamped in the tapered bore of a driving shaft 29 accommodated in a housing 32. The rear portion of the housing 32 contains the drive gearing and carries the hydraulic driving motor 38 for rotating the roll. The housing 32 is supported on a frame pivotable about a support shaft 45, the ends of which are eccentrically journalled in the side walls 20 of the carriage 19 so that a small amount of adjustment between the frame and the carriage 19 is possible. The frame is pivoted about the shaft 45 by an hydraulic cylinder 48 which cylinder together with the cylinder 28 for the pressure rolls 16 provides the rolling pressure, the inward stroke being limited by a stop 51 on the piston-rod. Spaced back-up rolls 52 journalled in the frame 42 support each roll 13 so that the latter may be relatively small. The lower roll assembly at each station is similar to the upper assembly except that the lower frame 42<SP>1</SP> is provided merely with a screw adjustment to suit the particular size of roll 14 selected. At the beginning of rolling the upper rolls are lowered on to the blank 15 by the cylinders 48 and the working rolls rotated by the drive motors 38 which are of the positive displacement type. During rolling the diameter of the work increases progressively and the carriages 19 are retracted in synchronism, the threaded shaft 61 being driven by an hydraulic motor 67 through an overrunning clutch. The work is rotated by the action of the rolls which are synchronized by a constant flow from a pump 72. A valve 73 is provided for speed regulation. In a modification, three work stations are again provided and the apparatus is generally similar in construction to that described above except that the upper roll housing at each station is pivoted by a single-acting hydraulic cylinder 148, Fig. 10, the nut 156 on the rod 152 acting as a limiting stop for the downward movement of the working roll 103. The roll housing is lowered i.e. the roll is raised by a pull-back cylinder 15, Fig. 12 (not shown). The various hydraulic drives for the mill, i.e. the drives for the working rolls, the pressure rolls, tilting adjustments and carriage retraction are hydraulically synchronized as before described.

Abstract: 1402797 Doped metal halides CIBA-GEIGY AG 7 Aug 1973 [17 Aug 1972] 37365/73 Addition to 1325825 Heading C1A [Also in Division B1] Doped metal halides in mono- or polycrystalline form are produced by reacting a doped metal with at least one halogen in a closed reaction vessel at 1-500 Torr at a temperature below the m.p. of the metal but above the m.p. of the halide so that the liquid halide drips on to a stationary or rotating base which is at a temperature below the m.p. of the halide. A doped metal or metal halide is one which only contains known quantities (usually traces) of foreign bodies very uniformly distributed. The temperature of the metal may be 400-1100‹ C. Silver doped with at least one of Fe, Ni, Au, Rh, Ir and S and obtained by zone melting is the preferred metal but groups IVa, Va, Via and REMs, e.g. Cr, Mb, Ni, Ta, Ti, Zr and La may be used. The base may be a rotating ceramic or quartz plate and the form of crystallization controlled by the temperature. The doped silver halides may be used in semiconductor technology or for photographic purposes. Reference has been directed by the Comptroller to Specification 1,040,611.

Filed: 1970-08-04
Abstract: 1278135 Positioning of stacker trucks BROWN BOVERI & CO Ltd 4 Aug 1970 [6 Aug 1969] 37555/70 Heading G4H [Also in Division B8] A robot fork-lift truck servicing racks of storage shelves has coarse drive systems controlled by remotely transmitted signals for both the movement of the truck along an aisle and elevational movement of the lift and fine drive systems for these movements controlled by sensors on the truck and lift. A further fine and coarse control system may control the lateral position of the lift to add or remove plattens from a shelf. In one arrangement, the sensors are mechanical arms which once the truck and lift have been coarsely positioned swing out and contact a shelving upright and a shelf edge. An encoder provides a digital representation of the arm angle and the truck and lift are finely driven until the angle is 90 degrees. Radiation sensors, such as ultrasonic devices may be used instead.

Dec. 19, 1930, No. 38283. Convention date, Dec. 19, 1929. [Class 8 (ii).] Solid carbon dioxide ice is produced by subjecting solid carbon dioxide crystals to centrifugal force while in the presence of its own gas under a pressure greater than atmospheric pressure. A container 1, the periphery of which may be shaped to form moulds, is rotated by a motor 5. The liquid is supplied to a pipe 12 through a valve 11 and exhaust takes place through pipe, 6 controlled by a valve 7. The valve 7 is first adjusted so that the liquid is converted.to dry solid and gas, further adjustment allows the liquid to remain in the liquid form and lubricate the crystals. The pressure in the chamber is then adjusted so that all the liquid is converted into solid or gas. Alternatively the liquid may be allowed to flow into the chamber 1 and then permitted to boil off, or frozen by external means. The liquid may also be pre-cooled and delivered to the pipe 12 in the form of a liquid containing solidified particles.
