Abstract: 1286663 Photographic cameras EASTMAN KODAK CO 9 Oct 1969 [11 Oct 1968] 49609/69 Heading G2A A photographic camera, having a holder 3 for receiving a percussion-ignitable flash-lamp unit in such a way that one of the ignition tubes 2 thereof is located at a firing position, is provided with means 30 for actuating the camera shutter 5 and striking the so located tube 2, the means comprising a pair of levers 32, 33 coupled together for common movement by a weak spring 34, but the coupling allowing of one of the levers moving to its operating position after the other lever has reached its operating position. The arrangement is shown cocked. Sequence of events A tab 11 of an operating lever 10 is depressed, thus causing an extension 15 thereof to rotate a release lever 20 clockwise (as seen) to free the means 30 for anti-clockwise movement due to a spring 39 attached to the drive lever 32. The striker lever 33 follows lever 32 due to contact of spacing extensions 36, 37. Eventually the lever 32 is stopped by a surface 50, but the lever 33 continues due to its inertia and eventually a portion 33a strikes an ignition tube 2 to fire the associated lamp. Before the lever 32 stops, its end 32a passes into a shutter actuating zone A and so operates the camera shutter. After percussive contact, the light spring 34 retracts the lever 33 so that the extensions 36, 37 are again in contact. During film advance, a cam 45 is rotated anticlockwise, thus causing a slider 41 to contact an arm 40 of the lever 32, Fig.2 (not shown) and rotate the unit 30 back to the position shown against the action of the drive spring 39. The end 32a rides over the end 27 of the release member 20. The camera shutter can be a pivotally mounted blade, Fig.3 (not shown), or have drive mechanism which is released upon impact by the end (32a) Fig.4 (not shown) or be electrically operated under the control of the lever (32) Figs.5 and 6 (not shown).

Title: New synthetic resins and process for the production thereof
Inventor: WAAG THEODORE
IPC: C08G2/00
Filed: 1963-12-31
Abstract: The invention comprises resins prepared by condensing dimethylolacetone with ammonia, primary amines, secondary amines, or amides. Polyamines other than polyalkylene polyamines and polyamides may be used.  The amides may be carboxylic amides, or urea, guanidine or derivatives thereof, or cyclic amides, e.g. caprolactam.  The condensation may be conducted with or without an organic solvent or water.  Cross-linking may be brought about by heat, or using a catalyst, e.g. NaOH, KOH, tetraethylammonium hydroxide or alkali metal alcoholates.  In preferred processes the dimethylolacetone is reacted first with ammonia or a primary amine or polyamine, then with an amide or secondary amine, or this order may be reversed, or all these components may be reacted simultaneously.  The products may be plasticized by incorporating long chain (C4- 18) primary amines. Foaming may be brought about by using a strong aqueous NaOH or KOH soln. as curing agent, or a blowing agent, e.g. benzene sulphohydrazide, may be employed. When alcoholic alkaline solutions are used the products are lacquers.  In examples resins are prepared by reacting dimethylolacetone with (1) an alkylamine and hexamethylene diamine, (2) an alkylamine and methylene dianiline, (3) ethylene diamine, (4) an alkylamine and caprolactam, (5) 25% aqueous ammonia, (6) urea, (7) methylene dianiline, and (8) an alkylamine. Of these products that of (2) is prepared in n-butanol and dibutyl adipate and cured with alcoholic NaOH, of (4) is milled with benzene sulphohydrazide and foamed, of (5) is foamed with conc. aqueous NaOH, of (6) is foamed by heating and of (7) is mixed with polyethylene glycol, tetrachlorethylene and conc. aqueous NaOH, and foamed. Uses.-Coating metals, wire varnishes; adhesives for metals, glass, stones and concrete; textile dressing, treating fibre and fleeces; bonding "fibre glass"; foam sheets; coating paper, impregnating wood; sealing compounds for floors; core-binding material.ALSO:Wood or glass fibre fleece is treated with a resin precondensate of dimethylolacetone with ammonia, primary or secondary amine or an amide.  A glass fibre fleece may be soaked with the resin then pressed, with heating, into strong pressed pieces.ALSO:Paper and metals may be coated with compositions comprising the product of reaction of dimethylol acetone with ammonia and/or a primary amine and/or a secondary amine and/or an amide.  The coating may be applied as insulator to wires and to glass fibre fleeces which may be pressed and heated to form pieces.  In Example 1 dimethylol acetone is reacted with an alkylamine and hexamethylene diamine and the product is used to coat aluminium, copper, brass, zinc and steel, being cured by heat.  In Example 2 dimethylol acetone is reacted with an alkylamine and methylene dianiline in n-butanol and dibutyl adipate, then mixed with alcoholic NaOH and used as a varnish for rusty iron, to which varnish coatings may be added.
