Title: Improvements relating to clutches
IPC: F16D11/16
Filed: 1955-02-22
Abstract: 821,610. Securing together rotary parts. GREVILLE, E. G. Dec. 22, 1955 [Feb. 22, 1955], No. 5273/55. Class 80 (2). A coupling comprises an outer driving member 2 and a hollow driven shaft 4 in which are pivoted pawls 5 having teeth 8 of the shape shown biased by springs 9 to engage with correspondingly-shaped slots 3 in the driving member, disengagement of the coupling being effected when the shaft 4 is stationary by inserting a splined &c. control-shaft (not shown) up the hollow driven shaft to engage balls 10 and push them radially outwards against the tails of the pawls, which are thus turned to the disengaged position. The coupling is particularly intended for use between a motor driven pump and a respirator, a worm-wheel 1 fast with the driving member 2 engaging a worm driven by the motor and the driven shaft 4 transmitting drive to the pump. If the motor fails &c., the control-shaft is inserted up the hollow driven shaft 4 to disengage the coupling, and is then oscillated or turned by hand in order to continue pumping.

Title: Fluorination of chlorine-containing derivatives of paraffin hydrocarbons
IPC: C07C17/20
Filed: 1952-02-28
Abstract: A process for the fluorination at elevated temperatures and pressure of chlorine containing derivatives of paraffin hydrocarbons by means of hydrogen fluoride in the presence of an antimony halide includes the step of performing the fluorination in the presence of thionyl chloride.  Hydrogen fluoride containing water may be employed provided thionyl chloride is added to the reactants in quantity equivalent to the water present in the hydrogen fluoride.  In examples: Trifluorotrichloroethane is obtained by heating hydrogen fluoride containing water with hexachloroethane under pressure in the presence of antimony pentachloride and thionyl chloride in the stainless steel vessel (1); difluorochloromethane is similarly obtained using chloroform as starting material (2); and trifluorochloromethane is similarly obtained using tetrachloromethane as starting material (3). Similar processes carried out in the absence of thionyl chloride for comparison show a rapid loss of catalyst efficiency with the production of difluorotetrachloroethane and monofluoropentachloroethane, monofluorodichloroethane and monofluorotrichloromethane and difluorodichloromethane respectively. The fluorine containing paraffin hydrocarbons obtained according to the invention may be used as cooling agents for refrigerators, as starting materials in the manufacture of fluorine containing plastics and as non-combustible solvents.

Title: Improvements in the manufacture and production of intaglio printing colours
IPC: C09D11/10
Filed: 1929-02-18
Abstract: 307,877. I. G. Farbenindustrie Akt.- Ges. March 15, 1928, [Convention date]. Ink for use in intaglio printing is prepared by incorporating finely-divided or dissolved colouring- materal with a solution in a volatile solvent of a resinous substance obtained from organic, vinyl esters or dibasic organic acids and polyhydric alcohols. The solvents preferably possess slight smell, and are relatively incombustible, examples being aliphatic alcohols containing less than six carbon atoms, glycol monoalkyl ethers, ketones. esters, or hydrocarbons of the benzene series. Other materials, such as coumarone resin, colophony, the condensation products of urea or its derivatives and formaldehyde, and the like, oleaginous materials, or cellulose derivatives can be added. According to examples, lampblack and the calcium salt of the azo dyestuff of aniline and 2 : 6-naphthol sulphonic acid are incorporated in a solution of polymerized vinyl acetate in cyclohexanone, ethyl acetate, and ethyl alcohol; and lampblack and the calcium salt of the azo dyestuff of 2-naphthylamine-1-sulphonic acid and #- naphthol are mixed with a solution in ethyl alcohol and glycol monoethyl ether of the resin obtained from phthalic acid and glycerol. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use alone of the resins obtained by the condensation of urea or its derivatives with formaldehyde, and states that a water-soluble solvent and water can be added to such a composition. In an example, lampblack and the calcium salt of the azo dyestuff of aniline and 2-6-naphthol sulphonic acid are ground into a solution of the condensation product of urea and formaldehyde in a mixture of iso-butyl and ethyl alcohols. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to covers for containers
IPC: A47J36/02
Filed: 1956-02-22
Abstract: 787,612. Containers :packaging popcorn. ROBINS, B. N., and MENNEN, F. C. Feb. 22, 1956 [Oct. 17, 1955], No. 5442/56. Classes 66 and 94(1). A container 10, Fig. 2, e.g. for popcorn 24 and fat 26 has a cover 28 formed with a flat central circular portion 30. a surrounding spirally folded portion 32 and a flat rim portion that is enclosed by the rim 22 of the container. When the container is heated, the gases generated by the fat cause the spirally folded portion 32 to unwind and the whole cover 28 to bulge outwardly as shown in Fig. 3 until it assumes the shape indicated by the broken lines. Sufficient space for the popping of the popcorn kernels is thus ensured. The cover is made by placing a flat plate 42, Fig. 6, with a circular opening therein on the material to be shaped and an inverted cup-shaped tool 48 is placed on the material in the centre of the opening. With pressure being applied simultaneously to the plate 42 and the tool 48, the tool 48 is rotated through a slight angle. This twisting action causes the spiral folds 32 to form. When the tool 48 is finally pulled upwardly the central portion 30 is pulled up out of the plane of the outer part of the sheet because the folds 32 tend to grip the tool 48. After the plate 42 has been removed a suitable die is utilized to cut a cover 28 of a size to fit the container 10. The cover 28 may be of aluminium foil.

Title: Process for Transforming Heavy Hydrocarbon Oils into Lighter Hydrocarbon Oils.
Inventor: CROSS ROY
Filed: 1918-04-03
Abstract: 126,103. Cross, R. April 3, 1918. Hydrocarbons, cracking. - Heavy hydrocarbons are converted into light hydrocarbons by distilling them under a pressure of 400-1000 lb. per sq. in., and passing the resulting vapours under the same pressure over and into contact with the cool, heavy hydrocarbons on their way to the still. The apparatus comprises a still 6 in which the oil, heated by circulation through a heated coil 16, vaporizes under pressure. The resulting vapours pass through a pipe 7 into a container 5, which is continuously sup. plied with cool oil by a pump 2, and from which the oil after it has taken up the heavier constituents of the vapours flows by a pipe 8 to the still 6. The requisite pressure is maintained by a valve 11 on the vapour outlet pipe 23. The distillation is usually effected at 300-450‹ C., and the pressure being 600 lb. per sq. in.

Abstract: 1310932 Windows W FRACH 20 Feb 1970 [20 Feb 1969] 5723/70 Heading E1J [Also in Division F2] A control device for hydraulically sealing or holding a window by pressure hoses 1, 2, 3 comprises two rotatably mounted pinion wheels cooperating with two displaceably mounted gear racks 9, 10 connected to moveable parts of two piston and cylinder arrangements 11, 12. In Fig. 2, shaft 19 is rotated in a clockwise direction to move rack 10 out of engagement with pinion wheel 4 by pressure of cam disk 13 on stop 17 and to move rack 9 into engagement with another pinion wheel behind wheel 4. Piston 12 is drawn towards the pinion wheels by rack 9, producing suction at the cylinder bore to empty hoses 3 and 1 (Fig. 1) which are connected by bores 7 and 8 into the cylinder bore. The window is thus unsealed on all sides except the lower horizontal and is free to tilt about horizontal axis 30. Anticlockwise rotation of the shaft from this position reverses the process to reseal the window until the position shown in Fig. 2 is reached. Continued anticlockwise rotation then releases pressure in hoses 2 and 3 to unseal the window and allow it to pivot about vertical axis 29.
