Title: Web Winding Apparatus
IPC: B65H18/16
Filed: 1967-06-07
Abstract: 1,186,428. Winding webs. BELOIT CORP. 7 June, 1967 [5 July, 1966], No. 26313/67. Heading B8R. In a single drum web-winding machine, upper and lower link arms 15 and 16, pivoted respectively at 18 and 22, pivotally support at 20 and 23, saddles 11 which rotatably support the ends of a core 10 of the web-roll being wound. This arrangement enables the core 10 to move in a substantially straight line away from the winder drum 24 as the web-roll diameter increases. In Fig. 1, a pair of pressure arms 27 also pivoted at 22 are associated with lower link arms 16. Frictionless air springs or diaphragm operated piston devices 33 are mounted on the pressure arms 27 and have piston rods 34 connected to the lower link arms 16. These devices 33 provide a constant nip pressure between the web-roll and the winder drum 24. As the diameter of the web-roll increases, movement of the lower link arms 16 relative to the pressure arms 27 operates a micro-switch (not illustrated), which causes a pair of hydraulic cylinders 28 to pivot the pressure arms 27, thereby accommodating the increase in diameter. In an alternative embodiment (Fig. 7), a uniform torque motor (71) mounted directly to a shaft (72) (i.e. the shaft 22, Fig. 1), provides a constant nip pressure, and replaces the hydraulic cylinders 28, the pressure arms 27 and the air spring devices 33 of Fig. 1. An empty core 38 is positioned within the jaws 39 of a pair of loading arms 40. With the upper and lower link arm assemblies 15 and 16 in the position shown in (Fig. 5), the loading arms 40 are rotated by rack and pinion 41, 42 to deposit the core in the saddles 11. When winding is completed, the web-roll is deposited on pick-up rails 45 pivotally mounted at 46. The rails 45 are tilted by hydraulic cylinders 50 causing the web-roll to traverse along the rails to stop 49. An arcuate brake-shoe 55 is raised by an air device 60 to brake the core of the completed web-roll, so that it can be removed by a crane or lifting device.

Title: Improvements in apparatuses for the measurement of viscosity and thixotropy
IPC: G01N11/14
Filed: 1936-10-06
Abstract: 482,950. Viscosirneters. GOODEVE, C. F. Oct. 6, 1936, No. 27043. [Class 106 (ii)] Apparatus for measuring viscosity and thixotropy consists of inner and outer coaxial cones the distance between the surfaces of which can be varied by axial movement of one relative to the other, and in which the rotation of one of them produces a drag on the other through a fluid placed between them. The Figure shows a form which can be dipped into the liquid to be tested. The outer cone A mounted on ballbearings B is rotated by a motor, not shown, via the gear C. The inner cone E is supported by the tube F and may have its ends hollowed out. The tube F fits into a tube G and is fixed thereto by a set screw H working in a slot J. Movement of the tube F is obtained by turning the nut K, the top of the tube co-operating with a dial on the nut K to indicate the separation of the cones. A dial M co-operates with a pointer N to indicate the angular displacement of the tube G caused by the viscous force on the cone E which is opposed by a clock spring P one end of which is fixed to the inner system and the other end to the casing R. Thixotropy can be measured by allowing time for the liquid to set after the insertion of the apparatus. The motor is then started and the inner cone carried around with the outer until the force exerted by the spring is sufficient to break the thixotropic structure and establish the liquid state. In a modification, the outer cone contains the fluid and fits into a holder with which it is rotated by variable speed gear driven from a motor. The inner cone is fixed to a thermometer tube suspended by a torsion wire. The distance between the cones is adjusted by a screw moving the whole suspension.

Filed: 1936-10-07
Abstract: 484,797. Copying images on lenticular colour films. NORDMANN, C. Oct. 7, 1936, No. 27284. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 8, 1937.] [Class 98 (ii)] In copying images on lenticular colour films onto lenticular material, the relative aperture of the lenticles of the copy film is less than the value of the relative aperture of the lenticles of the original film divided by the magnification ratio. The marginal bands between the component images on the copy are thereby reduced in width. The marginal bands on the original may be transparent or opaque and may be rendered opaque by an additional exposure during a reversal process applied to the original film. Figures 3 and 4 show the copying process effected by projection and contact printing respectively. In both cases the support of the copy film 8 may be thicker than that of the original 2. Means may be employed to illuminate only the central part of the monochromatic images or for intercepting light from the marginal parts. The original film may be taken in a camera having an objective of relative aperture not greater than f/4, and preferably less than half that of the lenticular elements. The Specification as open to inspection under Sect. 91 comprises also methods of copying onto non-lenticular material. This subjectmatter does not appear in the Specification as accepted.
