Filed: 1950-05-08
Abstract: 675,142. Grinding. PILKINGTON BROS., Ltd. May 8, 1950 [Sept. 8, 1949], No. 11456/50. Class 60. A method of grinding or polishing the two faces of a glass ribbon 1 which is advanced continuously by means of driving rollers 2, 2<SP>1</SP> disposed on opposite sides of the ribbon includes the step of applying a regulatable and determinable pressure to one roller of each pair in the direction of the opposing roller of the pair. Each end of the roller 2, Fig. 1, rotates in a .bearing integral with a housing 4 which is movable vertically and furnished with shoes 5 slidable in guides 6. This roller is driven from a motor through a gear train 10, 10', worm wheel 9, worm 8 and splined shaft 7, and, if desired, the lower roller 2' may be similarly driven from the shaft 7. Pressure is applied to the housing 4 by an axially-movable rod 11 having an enlarged lower end 13 located between two springs 12, 21 in an extension 18 of the housing 4. The upper screw-threaded end of the rod 11 engages an operating nut 16 in the form of a pinion which is rotated from a rod 14 by a pinion 15. The pressure on the glass is measured by, an indicator 19 carried by the end 13 and movable over a scale 20. If desired, pressure may be applied through the medium of one spring only. In the modification shown in Fig. 2, pressure is applied by a weight 25 slidable on a beam 22 which is pivoted at 23 and connected to the housing by a rod 21. Instead of applying pressure separately to the housings at opposite ends of a roller, one regulating device may be caused to act on both housings.

Abstract: 1,146,892. Adhesive coating. B. J. FRYE. 16 March, 1966, No. 11586/66. Heading B2E [Also in Division E2] A holding device for attaching an article to a supporting surface but allowing ready removal therefrom if so desired, and adapted to be adhered to the supporting surface comprises a flexible body portion having an inward peripheral slit extending at least partially thereabouts to form a marginal portion having separated portions with non-adherent means disposed between the separated portions. The major surface of the body portion of the device which adheres to the supporting surface may be naturally self-adhesive or coated with a pressure-sensitive adhesive. In one embodiment (Fig. 4) the device comprises a pair of superposed layers 12 and 14 of a flexible sheet material having naturally self adhesive characteristics such as plasticized polyvinyl chloride. The marginal portions 21 and 22 of each layer have their facing surface portions 25 and 26 made non- adhesive by interposing a sheet 29 in the form of a frame between layers 12 and 14 and formed of a material which will not bond with or adhere to the material of layers 12 and 14 e.g. cellulose acetate. The resulting sandwich-like arrangement is placed in a press and subjected to heat and pressure sufficient to bond or fuse together the central portions of the facing sides 17 and 18. Instead of a single sheet 29, there may be interposed two layers of frame-like material which are non-adhesive relatively to one another but which readily bond to the marginal portions 21 and 22 e.g. tissue paper. Alternatively a coating material may be applied to the marginal portions e.g. by silk screening. The device may be formed with a plurality of fused areas in spaced relationship (Fig. 8, not shown). The device may have one or both of its outward facing surfaces coated with a pressure sensitive adhesive, the adhesive coat being protected by a liner (Fig. 9, not shown).
