Patent GB-202306-A (GB)
Title: Process for the production of thin films of cellulose derivatives
IPC: B29D7/01
Filed: 1923-08-08
Abstract: Thin films of cellulose derivatives, more especially cellulose esters and ethers, are prepared by applying a solution of the derivative in a very thin layer to a base formed from a coated cellulose derivative other than that used for the production of the film or a similar cellulose derivative but having different solubility characteristics; the base material does not combine with the film and is preferably repellent thereto, so that, on drying, the film may be readily pulled off; when preparing the solution a solvent is selected which has no solvent action on the base. A base material may be rendered repellent by additions such as oils, fats, glycerine and salts, especially such metal salts as are soluble in alcohol. In the case of very thin films a softening-agent is added to the solution. The solution may be applied in the form of a solution by means of a pouring-machine, or in a viscous or pasty condition, spreading being effected by a roller, knife, etc.; the latter type of solutions dry more quickly and adhere less strongly to the base. Filling-materials, such as mineral powders, bronze powders and colouring-matters, may be added to the solutions; and plastifying-materials may be incorporated with the base. The surface of the base may be smooth or patterned. The Specification as open to inspection under Sect. 91 (3) (a) includes also the employment of a base soluble or slightly soluble in the solvent used in the preparation of the solution; the deposition of successive layers of different solutions which, after drying, may be separated one from the other; the preparation of a film of ethylcellulose by spreading an alcohol solution on a base of alcohol-insoluble cellulose acetate, to which glycerine, a glycerine derivative, or a mineral oil is added; the addition to the solution of a softening-agent that has preferably no solvent action on the base, e.g. linseed oil to a solution of ethyl-cellulose to be applied to a benzyl-cellulose base; the removal of the film before complete removal of the solvent.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to piston sealing means
IPC: F16J15/32
Filed: 1962-05-25
Abstract: 1,012,451. Piston and stuffing-box packings. J. L. GRATZMULLER. May 25, 1962 [May 26, 1961; May 8, 1962], No. 20223/62. Addition to 814,830. Headings F2B and F2T. [Also in Division F1] A seal assembly between two relatively displaceable inner and outer members 1, 2, Fig. 2, comprises at least two axially stacked rings 12, 13 of differing hardness which are continuously axially compressed in a space between facing cylindrical surfaces of the members against a radial surface of one of the members by means of a spring-loaded metal ring 7, the harder ring 12 being positioned between the ring 13 and the radial surface and being made of a material having self-lubricating properties which on sliding engagement with the surface of the other member deposits thereon a thin continuous film preventing or minimizing direct frictional contact between that surface and the ring 13. The members 1, 2 constitute the piston and cylinder of an oleo-pneumatic accumulator. The spring 8 is seated at one end against the ring 7 bearing and at the other end against a disc retained on the piston-rod by a spring clip. The ring 12 may be made from P.T.F.E. or polytrifluorochloroethylene and the ring 13 of an elastomer, e.g. neoprene, having a Shore hardness number of 60-80. When gas is introduced in the compartment 4 of the cylinder with the piston bearing against the cylinder end plate 26 on the oil-filled side, the ring 12 undergoes a slight degree of flow as at 12<SP>1</SP> and prevents any extrusion of the ring 13 between the piston and cylinder. In a modification, Fig. 3, the seal assembly comprises a ring 14 of non-binding metal, a ring 12 of P.T.F.E., two or more elastomer rings 15, 16 of different hardness, e.g. as a function of temperature, and a spring-seating ring 17 of non-binding metal. The spring 8 compresses the assembly through a sleeve 19 which has a tubular extension 20 abutting against the spring-retaining washer 9. In the uppermost position of the piston, when no gas is present above it, the washer 9 engages a shoulder 22 on the cylinder end 21 and transmits through the sleeve 19 to the seal assembly the entire oil pressure exerted on the piston. The retainer ring 10 for the washer 9 may be formed of piano wire and may be contained within a channel surrounding the piston rod and formed between facing bevelled portions at the inner peripheries of a pair of superimposed annular members secured together by crimping a flange of one on top of the other. In Fig. 5, the seal assembly forms part of a stuffing-box 28 secured to one end of a high-pressure cylinder 30 around a slidable rod 27. The ring 14 in that case also serves as a guide to the rod. A ring 31 of plastic material is provided to wipe off dirt from the rod.

Title: Improved process for the production of 11-bromoundecanoic acid
IPC: C07C51/363
Filed: 1953-07-23
Abstract: A process for the preparation of 11-bromoundecanoic acid is characterized in that undecylenic acid is treated with hydrobromic acid in the presence of an organic peroxide and in the absence of free oxygen.  An organic dehydrogenatable solvent may be present in the reaction mixture, e.g. "Tetralin" (Registered Trade Mark) or cyclohexane or toluene together with "Tetralin" or cyclohexane.  In the example, 11-bromo-undecanoic acid is obtained by passing hydrobromic acid into a toluene solution of undecylenic acid in the absence of air and using benzoyl peroxide as catalyst.  For comparison toluene solutions of undecylenic acid in toluene are treated with hydrobromic acid in the presence of a stream of air and in the presence of air and benzoyl peroxide when 10-bromoundecanoic acid is produced as a by-product.
