Title: Anti-halation layer or filter layer for photographic plates and films
IPC: G03C1/83
Filed: 1932-01-20
Abstract: 383,799. Photographic filter and antihalation layers. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on- Main, Germany. Jan. 20, 1932, No. 1766. Convention date, Jan. 21, 1931. [Class 98 (ii).] For the production of an antihalation or filter layer for photographic plates or films, an insoluble azo dyestuff is produced in a solution of a binding agent, and the solution is coated on the support or sensitized layer. In examples, anhydrous sodium carbonate and sodium #-naphtholate are added to a cooled gelatine solution and an azo dyestuff formed by stirring in a diazo solution of alpha-naphthylamine or dianisidine. The gelatine is allowed to solidify, out into pieces and washed. It is applied molten, in the known manner, to a support or an emulsion. When images are to be converted to positives by reversal, the azo dyestuff is decomposed by the usual oxidizing reversal baths, e.g. those containing potassium permanganate and sulphuric acid, and a special decolourizing bath, such as an hydrosulphite solution, is unnecessary.

Abstract: 1,262,133. Hair dryers. HOOVER Ltd. 13 Jan., 1969 [15 Jan., 1968], No. 1838/69. Heading A5R. A hood 10 for a hair dryer comprises rigid outer and inner shells 25, 26 separated to define an air chamber 27, the inner shell 26 being perforated and having a retractable extension 40 mounted thereon. The extension 40 is of the shape of part of a sphere, and is moulded from a transparent plastics material with a pair of integral pins 41 which extend through holes (42) in the inner shell 26 and which are secured in position by snap on clips (43). The travel of the extension is limited by a stop 44 on the inside of the shell 26 which engages a shoulder 46 of the extension, and a rivet 45 which limits the downward movement by engaging the same shoulder 46. Shells 25 and 26 are secured together by screws 29 in bosses 31 with their lower peripheral edges sealed by an annular gasket 31. When the hood is placed on a base unit (25) of the hair dryer as described in Specifications 1,262,132 and 1,262,131 the extension 40 is automatically retracted into the hood.

Abstract: 785,268. Claw clutches. BENDIX AVIATION CORPORATION. Jan. 19, 1956 [Feb. 1, 1955], No. 1882/56. Class 80 (2). Clutch claws 12, 11 on a member 14 splined in a driving shaft 1 and on a driven shaft 9 are normally held in engagement by a torsion spring 22 connected between a member 18 secured on the shaft 9 and a nut member 25 engaging the member 14 through helical splines 28, 29. The clutch is disengaged by applying a brake 32 to the member 25, resulting in complete separation of the helical splines 28, 29 and of the claws 11, 12, the parts being then maintained in this position by a spring-loaded plunger 49 in the member 14 abutting against the end of shaft 9. The clutch is reset by releasing the brake, turning the member 25 to stress the spring 22, pressing the member 14 towards the shaft 9 to re-engage the splines 28, 29, and releasing the member 25, whereupon the stressed spring 22 completes the engagement. The member 25 is axially positioned on the member 18 by a split-ring 26. The brake comprises a pair of brake shoes 34, 35 surrounded by a pair of garter springs 43 and connected at one end by a link 38 held by a fixed pin 38, the shoes being normally retracted, against the action of the springs 43, by a slidable rod 45, the lower end of which is held by a detent 48 between the free ends of the shoes.

Title: Fuel oil composition
Inventor: MCLEAN DONALD HENRY
IPC: C10L1/12
Filed: 1954-01-22
Abstract: A fuel oil containing vanadium is improved by determining the ratio of vanadium to other metals forming water-soluble ashes in the oil, and adding one or more akali metal compounds forming water-soluble ashes to the oil to bring the ratio to less than 2 : 1.  The added compound may be a sodium salt, which may be oil-soluble, such as an organic salt, which is dissolved in the oil, or an inorganic salt which is suspended in the oil.  A particular example is sodium chloride which is added as an aqueous solution and emulsified with the oil.  Preferred organic salts are sulphonates, naphthenates or fatty acid salts.  Preferred inorganic salts are chlorides and carbonates.  Oil-soluble compounds may be salts of acids obtained by oxidation of petroleum fractions and low molecular weight fatty acids salts, e.g. acetates, solubilized by higher molecular weight salts. When sulphur is present in the oil the compound may be one that forms a water-soluble sulphide; otherwise one forming a water-soluble vanadate or oxide is used.  Magnesium compounds may also be added to the oil, together with the alkali metal compound.

Abstract: 1,178,072. Purifying esters. MELLEBEZONS. 15 Jan., 1968 [9 Feb., 1967], No. 2216/68. Heading C2C. The invention relates to a process of purifying high-boiling esters (boiling above 250‹ C.) obtained by esterifying an acid or acid anhydride with a molar excess of an alcohol having at least 4 carbon atoms followed by neutralizing and washing with water. According to the invention the esters so obtained are stripped with superheated steam and/or a hot vehicle gas by a process effected in at least two stages under successively decreasing pressures. Thus, the process may comprise a first stripping effected under atmospheric or moderately raised pressure. a second stripping under moderate vacuum and a third stripping under high vacuum, or the second or third stripping may be omitted. Specified esters which may be treated include di-decyl phthalate, di-tridecyl phthalate, di-n-butyl phthalate, dihexyl phthalate, dioctyl phthalate and di-2-ethyl hexyl sebacate. Apparatus is described and examples are given. Specification 934,027 is referred to.

The tank or pan 1 is provided with a jacket 2 through' which a cooling or heating medium can be circulated, and is also provided with a central vertical tubular shaft 12 which serves as a bearing for a central shaft 11. A V-shaped member 14, secured to the head of the shaft 11, has triangular bases 14<a> the leading edges x of which are curved so as to urge the material outwards towards the wall of the pan. Plates 16, secured to vertical brackets 15 carried by the members 14a, have curved arms 17, shaped as shown, which direct the material from the wall of the pan towards the centre, at the same time turning it over.
