Abstract: 733,966. Spring clips. POOL, J. H. (Vielle, J.). Aug. 12, 1953. No. 22279/63. Class 44. A spring clip comprises a piece of flexible sheet material bent into two opposed jaws 1, 2 each of which is constituted by a substantially V-shaped arrangement of limbs 5, 6, the limbs of one jaw being in continuity with the limbs of the other jaw, the two jaws being each formed with a longitudinal indentation 8 extending from the junction of the appropriate limbs to the free end of the associated jaw the arrangement being such that by pinching together the limbs the jaws are deformed so as to separate their free ends, the resiliency of the clip material yieldingly opposing this separation of the free ends of the jaws so that upon releasing digital pressure upon the limbs the free ends return to their normal relationship to grip on documents or other articles to be gripped. The pinching together of the limbs produces a leverage at the point where the limbs 5, 6 meet, the jaws bending about the indentation 8 and moving apart. The jaws may end in a pair of prongs 9 as shown or each in a single V-shaped prong, the opening of the V being adjacent the indentation 8.

Abstract: 1369538 Winding MAILLEFER SA 12 May 1972 [26 May 1971] 22351/72 Heading D1J Each bobbin of a winding machine is surrounded and protected by a part-cylindrical shield which is withdrawn axially of the bobbin to allow bobbin loading and unloading. In the continuous winder shown, bobbins 1, 2 are mounted on turret 3 rotatable on shaft 4. Winding is started on a bobbin in the upper position and finished with the bobbin in the lower position. Bobbins are loaded and unloaded by device 13, and strand is traversed by carriage 19. The bobbins are covered during strand winding by cylindrical shields 25, 26 which are withdrawn by jacks 34, 36 via arms 33, 35. Each shield has a longitudinal slot through which the strand is passed. Each shield is oriented by cam means during movement of the associated bobbin from its upper to its lower positions so that the edges of its slot do not contact the moving strand. During the winding of the bobbin in the lower position, the running coine presses on the upper bobbin core. When the lower bobbin is full -the wire is stopped near the left hand bobbin ends, and the upper cover 26 is advanced from its retracted position either to snap the wire or to engage the wire with a cutter. Winding is then resumed on the upper bobbin. Alternatively, axially-shorter covers may be attached to the traversing mechanism.

Patent GB-350310-A (GB)
Title: An improvement in the manufacture of cellulose acetate
IPC: C08B3/24
Filed: 1930-07-25
Abstract: Cellulose acetate produced in known manner and hydrolysed to the desired extent is treated with dilute hydrochloric acid prior to precipitation.  Cellulose acetate thus treated leads to the formation of films free from haze which are particularly suitable for photographic purposes.  The strength of the hydrochloric acid and the time of treatment are such that no further hydrolysis occurs.  In general, a concentration not exceeding 1 per cent of hydrochloric acid based on the weight of the solution is used.  In an example, a cellulose acetate dope which has been hydrolysed to the desired extent is stirred for half an hour with hydrochloric acid mixed with acetic acid.  It is then poured into a bath of dilute acetic acid and the product is washed and dried.  The cellulose acetate thus produced, when dissolved in acetone with a plasticizer and spread on a forming-surface, gives a transparent film free from haze.

[Class 98 (ii)] Colour photographs and kinemanograph films are produced by printing from a multi-colour picture, which has been produced by colour development of a multi-layer light sensitive material, by coloured printing light absorbed only by the colour of the part layer in the multi-layer material on to separate colour sensitive material to obtain black and white partial images, and using the black and white partial images either as master images or as intermediate images in printing on to multilayer light sensitive material. A bipack may be used comprising one film with two differently colour sensitized layers and another film with a single layer. The two layer film is exposed through the support. The layer next the support is blue sensitive and contains thioindoxyl carboxylic acid, and the top layer is green sensitized and contains a decolorable yellow filter dyestuff and alpha-chloracetoacetic ester. The film is developed with diethyl-p-phenylenediamine. The single layer on the rear film is red-sensitized. In a modification, a pack comprises a blue-sensitive front film and a rear film comprising an upper green sensitized layer containing a yellow filter dyestuff and alpha-chloroaocetoacetic ester and a red-sensitized lower layer containing thioindoxylcarboxylic acid. The layers may be on opposite sides of the support. After development and fixing, the metallic silver is removed with Farmer's reducer. Black and white images are obtained from the colourdeveloped two layer film using yellow, or green, and blue filters successively. The material on to which the black and white images are printed may contain dyestuffforming components or dyestuffs, or the dyestuff forming components may be present in the developer. The colour development may be performed by fractional development. The silver images in the black and white pictures may be transformed into silver halide and colour developed.

Title: Improvements in or relating to the manufacture of transparent cellulosic sheets and films
Inventor: SANDERSON EDWARD GEORGE
IPC: C08J7/046
Filed: 1954-08-03
Abstract: Smooth transparent non-fibrous and substantially non-porous water-sensitive sheet cellulosic material is sized with a relatively thin coating of an anti-sticking agent comprising a water-soluble salt of an alkenyl amine which is liquid at 25 DEG  C. and the alkenyl group of which comprises an 8-22 carbon atom chain having a single ethylenic double bond, or a salt of a reaction product of such an amine with ethylene oxide which is liquid at 25 DEG  C., the salt having been formed by neutralization of the amine or the reaction product with an organic carboxylic acid or with hydrochloric acid; the salt is applied as an aqueous solution and the film is thereafter dried.  The reaction product of the amine with ethylene oxide may contain 1 to 10 ethylene oxide units per molecule.  The amine salt may be D 9-octadecenylamine acetate or hydrochloride or N,N-dimethyl-D 9-octadecenylamine lactate.  The cellulosic material is preferably regenerated cellulose film produced from viscose or cuprammonium cellulose, but may be a film cast from aqueous or alkaline aqueous solutions of lowly substituted cellulose ethers or esters.  Gel regenerated cellulose film may be passed in a continuous length through an aqueous solution of the salt of the amine or of the amine-ethylene oxide reaction product, which solution may also contain a softening-agent such as glycerine and/or a water-dispersible partially condensed melamine/formaldehyde or urea/formaldehyde resin or a water-dispersible polyalkylene imine. The solution may also contain colloidal silica and/or alumina.  In an example, regenerated cellulose film produced from viscose is passed first through an aqueous bath at 60 DEG  C. containing 0.1 per cent of D 9-octadecenylamine acetate and 5 per cent of glycerine and then between squeeze rolls and over drying rollers heated to 80-90 DEG  C. In another example, regenerated cellulose film is similarly treated with an aqueous solution containing dimethyl-D 9-octadecenylamine lactate, polyethylene glycol (mol. weight 300) and cationic dispersed urea/formaldehyde resin. Examples are given also of the coating of regenerated cellulose treated according to the invention with typical moisture-proof coating compositions (see Group VIII).  Specifications 623,357, 673,255, 675,477, 697,322, 738,080 and U.S.A. Specification 2,137,274 are referred to.
