Abstract: 894,869. Vehicle parking systems. WULLSCHLEGER, A. May 13, 1960 [Dec. 22, 1959], No. 16931/60. Class 78 (1). In a vehicle parking system having cabins 1 suspended from axles 2 extending between a pair of endless chains 11, the cabins are prevented from swinging, over those portions of their path where the chains are deflected around pairs of chain wheels 12, 13, by star wheels 22, 23 driven in synchronism with the wheels 12, 13 and rotating about axes offset from the axes of wheels 12, 13, respectively, the star wheels having projections 27 which engage flared ends of guide channels 28 on the cabins. The star wheels 22, 23 are driven from the wheels 12, 13 by sprocket connections 25. Spur gears may alternatively be used. Each guide channel 28 is arranged vertically, to extend upwardly and downwardly from the corresponding axle 2, the arrangement being such that the point of engagement of a projection 27 with the guide channel 28 is displaced vertically from the axle 2 by a distance equal to the separation of the axes of the corresponding star wheel and chain wheel. Each axle 2 is connected to the chain at each side of the system by a universal joint comprising a bearing 3 for the axle 2 which carries a swivel pin 3a journalled in a bearing 5a which is secured between a pair of T-shaped links 5 incorporated in the chain 11. The cabins are also prevented from swinging on the straight vertical runs of the chains by chain guides 14, 15 and cabin guides 16, 17 engaging rollers 18, 19 on the cabin. In a second embodiment, Fig. 5, extended links 35 are used in place of the T- shaped links 5 to support the axles 2, so that the star wheels 41, 42 have to be offset upwardly or downwardly and to one side with respect to the chain wheels and the guide channels 43 on the cabins inclined to maintain the cabins in vertical depending position. The chain guides are omitted, since on the vertical straight runs the axles 2 are in alignment with the path of the chains. The invention is applicable also to arrangements wherein the endless chains include horizontal or inclined stretches and where chain wheels engage the chains on the outside of the chain path.

IPC: B41F13/54
Filed: 1930-06-02
Abstract: 356,707. Sheet cutting, folding, and associating apparatus. GOSS PRINTING PRESS CO., 1535, South Paulina Street, Chicago, U.S.A. - (Assignees of Smith, E. J. ; 18, White Friars Street, London.) June 2, 1930, No. 17044. Convention date, June 13, 1929. [Class 100 (i).] Sheet cutting, associating, and folding apparatus, more particularly for application to fast rotary web-printing presses, comprises mechanism in which the sheets from each web or group of webs may be collected before being folded and, whether collected or not, may be associated with the sheets from the adjacent group of webs before folding. One group of webs passes over a former 1 and between. a cutting roller 69 and a folding roller 25, the latter roller having pins 31, 49 which impale the leading ends of the cut sheets and carry them into position to be folded into rollers 199, 200 by blades 28, 29 in the usual way. Impaling pins 75 are also provided on the cutting rollers 69 so that, if desired, the sheets can be collected on the cylinder 69 before being taken by the cylinder 25 and folded. A similar arrangement of former 100, cutting cylinder 169, and folding cylinder 121 is provided for a second group of webs. A transfer cylinder 220 with impaling pins 222 is arranged between the cylinders 25, 121 so that when the sheets from the two groups of webs are to be associated, the sheets on the cylinder 121 are taken by the cylinder 220 instead of being folded into the rollers 207, 208 and are transferred to the pins on the cylinder 25 carrying the sheets from the first group of webs, and the combined sheets are folded together. Arcuate guides 250 prevent the sheets slipping off the impaling pins. In order that the cylinder 220 may be adjusted relatively to the cylinders 25. 121 and according to the thickness of the product, its shaft 232 is carried in eccentric bearings 236 adjusted by hand-operated gearing 242, 243. Further the bearings 236 are mounted in blocks 237 slidable in the main framing so as to be capable of fine lateral adjustment by a screw 238.

Filed: 1937-06-19
Abstract: 495,579. Making carbon coated stationery. BAILEY'S PRINTING INVENTIONS, Ltd., and BAILEY, J. June 19, 1937, No. 17090. [Classes 100 (ii) and 100 (iv)] Carbon papers etc.; printing processes stenciling - apparatus.-A method of coating a web or sheet with duplicating medium includes the step of performing a printing, perforating, or cutting operation on the web or sheet, and a further step of coating, by a spraying operation, a part or parts of one side of the web or sheet with duplicating medium, these steps being performed in synchronism so as to ensure a definite and fixed relationship between the parts of the web or sheet treated or affected during the two operations. Apparatus for treating a web which is to be printed comprises a printing-cylinder 5 co-operating with an impression cylinder 6, and a train of inking-rollers 7 supplied with ink from a fountain 8. The paper web 13 to be treated passes from a roll 14 over guide rolls 15, between the cylinders 5 and 6, around further guide rolls 15, and beneath a second impression cylinder 16 beneath which a spraying-apparatus is situated. The cylinder 15 is driven from the cylinder 6 by means of a chain 21 and sprocket-wheels, and gearing 20. The spraying-apparatus comprises a vessel 22 into which dips a jet which extends within an outer jet or nozzle 24 with which a tube 25 communicates, the latter being connected with an air pipe 26 provided with a control valve which is mounted for rotation within the pipe 26. Air discharged from the tube 25 into the outer nozzle 24 acts to draw duplicating medium from the vessel 22 through the inner jet in the form of a spray which is directed on to the web 13 through a conical mask 29. Excess duplicating medium is collected by a container 30 and returned to the vessel 22. The valve in the air pipe 26 is operated mechanically by gears 32, 33 connected to the gearing 20. The web 13 after receiving the duplicating medium passes around a cylinder 35 heated by steam, hot water, &c., then around a further cylinder 37 supplied with cooling fluid, the cylinder 37 being driven from the cylinder 15, and the cylinder 35 being driven from the cylinder 37. Several spraying-devices may be used to coat different sized patches of duplicating medium on the web. The mask 29 may be arranged to move upwardly into contact with the web, and then move along with the web at the same speed as the latter during the spraying operation. The duplicating medium coating may comprise a combination of pigment and wax, or separate superposed coatings of pigment and wax may be applied separately. The coating may be applied either hot or cold. If desired, the coating operation may be conducted in synchronism with operations other than printing operations, as, for example, perforating, numbering, or cutting or trimming operations.

Title: Eccentricity correction in a rolling mill
IPC: B21B37/66
Filed: 1973-04-10
Abstract: 1467446 Rolling mills DAVY-LOEWY Ltd 3 April 1974 [10 April 1973] 17126/73 Heading B3M In a method of operating a rolling mill, the roll gap is initially set to zero with the rolls under load, and the eccentricity of the rolls is measured and stored in a computer, the measured values being subsequently used during a rolling operation to compensate for the measured eccentricities. In the case of a twohigh mill, the eccentricities of the work rolls are sensed, whereas for a four-high mill the backing roll eccentricities are used. During the initial measuring phase, the relevant rolls are rotated for at least one beat cycle, i.e. the roll of the pair with a slightly smaller diameter is rotated until it has made one revolution more than the other. The method can also be additionally applied to the work rolls of a four-high mill, and if the work rolls are driven from a common pinion stand only the sum of eccentricities need be measured. In an example, Fig. 1, the upper backing roll 10 is adjusted by hydraulic rams 14A fitted with position transducers 24. The rolling load is measured by load cells 16, and the hydraulic pressure by transducers PT. During the measurement phase, either the load is kept constant and the ram extension is sensed by transducers 24, or the extension is maintained constant and the load changes are measured, to provide the eccentricity values. During rolling the pressure applied to the rams is controlled by units 22 in response to signals from a computer 40 in which the eccentricities are stored. The signals are fed to the units in synchronism with rotation of the rolls 6 and 10, as determined by angular position transducers 26.
