Title: Transparency Frame
IPC: G03D15/10
Filed: 1966-07-06
Abstract: 1,155,709. Transparency frames. GEIMUPLAST, PETER MUNDT K.G. July 6, 1966 [July 7, 1965; Oct. 15, 1965; April 21, 1966], No.30353/66. Addition to 1, 071, 402. Heading G2C. A frame for a photographic transparency has an opening for insertion of the transparency, of which one lip is resiliently movable away from the other. In the arrangement of Fig. 2, the frame 2 has an opening 14 at one edge which is formed between two lip portions 11, 11<SP>1</SP> which can be flexed away from each other to admit the transparency 30. As shown, the flexing is effected by wedges 26, 27 acting in the direction of insertion (32). The wedges can also act transverse to this direction Fig. 3 (not shown), or the lips can be drawn apart by suction devices Fig. 1 (not shown). In the modification of Fig. 9 the frame is formed by a flat member 67 fitting within the rim of a surrounding frame member 65. The end of member 67 can be flexed upwards, as by the insertion of two pins 70, 70<SP>1</SP> through holes in member 65, while the transparency 69 is inserted, and then released by withdrawal of the pins. In a further modification, Figs. 6, 7, one frame portion 35 lies within the ridged edges 36, 37 of the other frame portion 34. Lugs 42-45 on portion 35 engage in openings 38-41, so that it has cantilever ends. This form of frame can also be opened by pressing ridges 36, 37 towards each other, which causes the central parts of the two frame portions to separate over their whole length.

Title: Improvements relating to Photographic Type Composing
Inventor: ASTLEY EDWARD THOMAS
IPC: B41B27/28
Filed: 1966-07-06
Abstract: 1,185,626. Photographic type-composing apparatus. CROSFIELD ELECTRONICS Ltd. 3 July, 1967 [6 July, 1966], No. 30375/66. Heading B6W. Matrix characters on continuously rotating drum 1 are illuminated by a flash tube 2 to pass the image of a selected character via a prism system 3 on to an electronic camera tube 5, which sends a video signal corresponding to the said character to an electronic display means, e.g. cathode ray tube 7 where an image of the character is formed, the position of the image being controlled, to record the character in a required position on film 9, by deflection control circuits. The input of justified or unjustified character information may be by magnetic tape at 21, perforated tape at 20 or computer at 22. Character information is temporarily stored together with the position of each required character and may be subsequently justified. A store may be provided containing a location for each matrix character, and when a character is in a position to be focused on tube 5, as determined by pick-up 27, location interrogating means investigate the corresponding character location to see if the said character is required. If the character is required flash tube 2 is energized. To obtain the required deflection of a character on the face of tube 7 two areas 32 and 33 are provided one for a positioning spot and one for character generation. A positioning spot is focused on to a grating 36 divided into character spacing increments by rows of vertical bars. The number of steps of a positioning spot across the grating as determined by photo-tube 37 is compared with the required spot position until correspondence is obtained. The spot is then moved into the character generation area. Film 9 may be moved stepwise between lines. Linespacing may also be adjusted by deflection of the character image on tube 7. Alternatively film 9 may move continuously, corresponding correcting deflections being applied to the characters formed on tube 7. The matrix may comprise a series of rings of characters with different type faces a series of tubes 2 being provided. Two cathode ray tubes 7 may be used, each supplying one half of each line. The characters may be deflected on the face of tube 7 for subscript and superscript notation.
Patent GB-830841-A (GB)
Title: A process for dyeing and impregnating animal leather
IPC: C14C9/00
Filed: 1957-09-27
Abstract: A solution in an organic solvent containing both a di-isocyanate modified polyhydroxy compound having free hydroxyl groups, and also a polyisocyanate, is applied to leather during or after its dyeing or colouring with a soluble or insoluble dye or insoluble pigment. Preferably, the solution also contains an accelerator for the reaction between the modified polyhydroxy compound and the polyisocyanate and the dye or other colouring matter may be dissolved or dispersed in this solution.  Insoluble inorganic or organic pigments, or dyestuffs soluble in the solvents used for the solution, as for example cellulose acetate disperse dyes, or chromium-containing metallized dyes may be used. The diisocyanate-modified polyhydroxy compound is prepared by reacting polyhydroxy compounds of relatively high molecular weight, e.g. polyesters of dicarboxylic acids and dihydric and polyhydric alcohols, with diisocyanates, e.g. toluylene-, hexamethylene-, p-phenylene-, or 4,4-diphenyl-methane-diisocyanates.  The diisocyanate is used in a proportion such that the diisocyanate-modified polyhydroxy compound obtained still has free hydroxyl groups, so that, when applied to the leather, it cross-links with the polyisocyanate added to form a product impervious to water and organic solvents used in dry cleaning.  Suitable polyisocyanates include known monomeric polyisocyanates, and reaction products of polyhydric alcohols and diisocyanates which still contain isocyanate groups as, e.g., those of 1 mol. of hexanetriol with 3 mols. of toluylene- or hexamethylene, diisocyanate.  Suitable solvents include ethyl acetate, acetone, the methyl ether of glycol acetate, trichlorethylene, methylene choride, benzene and mixtures of these. The solution may be applied by spraying or dipping, and drying and cross-linking may be accelerated by gently heating the leather. Accelerators which may be added to the solution include organo metallic compounds, e.g. of the titanic acidstearyl alcohol ester type, in conjunction with reaction products of phenyl isocyanate with tertiary amines.  Leather treated as described above exhibits an improved "handle," resistance to rubbing, and water-repelling properties, and the dyeing is fast to washing and dry-cleaning.

A plurality of heads 3 are supported a predetermined distance from a drum 8 by pneumatic servo-action. Tubes 9 mounted at opposite ends of a head-block 2 closely approach the drum and back-pressure in the air flowing out of them is communicated to bellows 12 arranged to move a U-form member 1, carrying the block 2 relative to a fixed member 4. Compensating bellows 19 are fed through a high impedance from a common pressure source 18 to oppose the bellows 12, the balance-point, and hence the head/drum spacing, being set up by needle-valves 16. The high impedance supply to the compensating bellows prevents a rapid approach of the heads toward the drum when the pressure is applied. A relatively weak spring 25 retracts the heads from the drum when the pressure is cut off. In another form of the apparatus, not fully described, springs may replace the compensating bellows.
