Title: Improvements in Show-cards and other Display Devices and the like.
Inventor: LOCKETT WILLIAM JOHN
IPC: G09F7/00
Filed: 1919-03-15
Abstract: 136,414. Lockett, W. J., (trading as Cash & Clare). March 15, 1919. Ornamenting.-Relates to showeards and other devices for display purposes of the type in which a protecting surface of gelatine, xylonite, or other flexible transparent material is secured to the face of the card, and consists in arranging the transparent material a to cover a part only of the card, so as to leave an unprotected portion representing a picture frame or background. Fig. 1 shows an imitation of a seal. When the material a covers, say, a letter, it is of a shape different from the letter. The material a may be of any colour. The invention may be applied to illuminated addresses.

Abstract: 1,178,743. Coated substrates. A. G. PITTMAN and W. L. WASLEY. 10 Feb., 1967 [10 Feb., 1966], No. 6537/67. Headings B2E and B2K. [Also in Divisions C3 and D1] Textiles and glass slides are treated with a) monomeric compound of the general formula: (wherein X, X<SP>1</SP> each are a halogen atom, Y is halogen or alkoxy or aryloxy, R is H, or monovalent hydrocarbon or monovalent halohydrocarbon radical, m=2 or 3, n=1 or 2, R=1, 2 or 3, q=0, 1 or 2, and (n+p+q)= 4) or b) a linear or a cross linked homopolymer or interpolymer derived from the monomer a) where p is only 2 or 3. The polymer may have recurring units of the general formula: (wherein X, X<SP>1</SP>, R and m are defined above, a=0 to 1, b=1 to 1.5, c=1 to 2 and (a+2b +c)=4. The polymers of the invention are applied to the fibrous material in conventional manner, dissolved in an inert volatile solvent such as Cl 3 CCF 3  or in an aqueous emulsion. The treated substrate is then subjected to conventional curing in order to bond the polymer to the fibres. The monomers, in the form of vapour, pure liquid or solution in an inert volatile solvent may be applied to the fibrous substrate whereby reaction occurs with reactive sites on the fibres and bonding occurs. Fibrous materials such as paper, cotton, linen, hemp, jute, ramie, sisal, rayons, ethyl cellulose, natural proteinous fibres, leather, fur, nylon, polyacrylonitrile polyurethane, polyethylene terephthalate, asbestos or glass, amongst others, may be treated with compounds of the invention. In Example 19 the monomer 3- (heptafluoroisopropoxy) propyltrichlorosilane in toluene solution is applied to swatches of wool and cotton with subsequent drying in air. In Example 22 the polymer, derived by hydrolysis of the monomer used in Example 19, is dissolved in Cl 3 CCF 3  and swatches of wool fabric are immersed therein, air dried and cured at 150‹C. Reference has been directed by the Comptroller to Specification 869,343.

Lasting and pulling- over. - A lasting-machine comprises a mould formed of a large number of adjacent grippers flexibly mounted and adapted to conform to the forepart or heel of various lasts. As shown, the edge of the upper is spread on the fixed jaws 25, Fig. 2, of the grippers. clamped by the movable jaws 26, the last pressed down into the upper by a foot 249 operated by a pedal, and a binding wire 42 drawn into place to secure the upper. The grippers are supported by projections 38 on the fixed jaws sliding between semi-circular plates 7, 8, 'the latter being resiliently supported on springs 17. The movable jaw 26 of each gripper is operated by links 52, 53, 27 and spring arms. 278, Fig. 17, on a rooking plate 57 supported on a slide 89 controlled by a flexible band 163 and springs 303. A groove 23 at the base of each fixed jaw accommodates a cable which is tightened when, for small work, some grippers are removed. A leather band 39 is housed between projections on the fixed jaws. The grippers are arranged in groups so that the various groups may be actuated in predetermined sequence. Each rocking' .plate 57 controls the grippers of one group, and is operated by one of several cams on a shaft 211 rotated by a handwheel or by power: Each cam has a recess 292 to ease the pressure of the grippers and allow slight withdrawal of the upper from the group of grippers controlled by the cam. The cam-shaft is longitudhially adjustable to enable the end gripper groups to be rendered inoperative for small work. The work support is movable about a vertical sleeve 225, is counterbalanced by weights 220 and held in vertical position by friction plates adjusted by a hand-wheel 222. It is movable to and from the mould by a pinion 227 turned by a handle adapted to be locked in adjusted position, and is tilted by a hand wheel 235. A chambered spindle 265 is provided for supporting the heel pin of the last while the heel-end is being lasted. Before lasting, the wire 42 to be used as a binder is housed in a recess 24 in the fixed jaws of the grippers. It is drawn tightly into place when necessary by a hand-wheel 243, and secured by tacks. A rack and pinion may be provided for quickly taking up the slack of this wire. An indicator 266 on the foot 249 co-operates with lines 267 on its support 250 to enable a previous position of the foot 249 to be repeated. The pincers described in Specification 125,481 may be substituted for those shown.
