Title: Improvements relating to the permanent deformation of keratinous fibres
IPC: C07J1/00
Filed: 1960-07-22
Abstract: Hair and other keratinous fibres are permanently deformed by constraining the fibres to a desired configuration, treating them at room temperature with an aqueous solution comprising a salt of a mercapto carboxylic acid with an organic base and a carbonate of an organic base and having a pH of 7-9, and then setting the configuration of the fibres by oxidation.  Salts of thioglycollic and thiolactic acids are preferably used in concentrations of 0.3-1.5 mols per litre and the preferred organic bases are guanidine, monoethylamine, monoethanolamine, monoisopropanolamine, diethanolamine and morpholine.  The concentration of the carbonate of the organic base may be 0.1-1.5 mols per litre.  The treating solution may be prepared by exactly neutralising a mercaptocarboxylic acid solution with an organic base and adding thereto the required quantity of the carbonate of an organic base, or a slight excess of an organic base over that required to neutralise the acid may be added to a solution of a mercapto carboxylic acid and carbon dioxide passed into the solution to convert the excess base into its carbonate.  The hair may also be impregnated with the aqueous treating solution before being wound on curlers.

IPC: B22D7/10
Filed: 1965-06-18
Abstract: 1,116,373. Mould linings. H. J. DAUSSAN. 18 June, 1965 [18 June, 1964; 26 Sept., 1964], No. 25831/65. Heading B3F. A lining for an ingot or similar mould comprises a unit B constituted by at least two tubular members 1 and 2 positioned one inside the other and defining between them an annular space, the inner member 2 being non-deformable, the outer member 1 being deformable so as to be sealingly engageable with the inside surface of an ingot mould when a casting is being poured. Spacer members 4 and 3 are positioned between the members and are located at the top and bottom, respectively, on the outer surface of the inner member. A sleeve 5 inserted between the spacers and the inner surface of the outer member 1 is movable parallel to the axis of the unit and has a wedge portion 7 at its lower end so that pressure exerted on the top end of the sleeve 5 urges the wedge portion 7 into a clearance gap 8 between the spacers 3 and the outer wall so as to deform the wall 1 outwardly into sealing engagement with the wall of an ingot mould into which the lining is inserted. In the embodiment shown in Fig. 1, the lining is shown positioned in an ingot mould, the inner walls of which diverge towards the bottom. The deformation of the outer member by the wedge action of the sleeve 5 is facilitated by the provision of longitudinal slots 9 in the lower region of the outer tubular member, similar slots 11 being provided in the sleeve 5. In the embodiment shown in Fig. 3, the lining is shown inserted in an ingot mould in which the inner walls diverge towards the top and the deformation of the outer member is effected by a wedge member 16, 16a inserted at the upper end of the unit. The initial positioning of the lining within the mould may be effected by a collar 35 which is clampable around the outside of the unit and which rests on the top edge of the mould. Alternatively metal strap members may be provided. In a further embodiment, Fig. 9, wedging sleeve 31 is positioned at a predetermined position in the mould and the tubular unit is inserted to engage the sleeve and as a result of pressure on the top of the unit the outer member of the unit is deformed and is thus wedged in position within the mould. The wedge member 31 may vary in shape depending on the type of ingot mould used. In a further embodiment the tubular unit is inserted into a tapered ingot mould and deformation of the outer wall is effected by direct contact between the outer member and the wall surface when pressure is applied to the unit. The annular space between the two members of the unit may be filled with a heat-insulating material such as, rock-wool, kaolin-wool, or blast furnace slagwool. The lining unit may be formed of a flexible material which can be folded to facilitate stacking and transportation.

Title: Improvements in the production of cycloaliphatic alcohols and ketones by oxidation of cyclo-aliphatic hydrocarbons
Inventor: SIMON WALTER
Filed: 1958-08-13
Abstract: In a process for the production of cycloaliphatic alcohols and ketones, by the oxidation of cycloaliphatic hydrocarbons in the liquid phase with oxygen or oxygen-containing gases in a plurality of successive oxidation-vessels, the oxidation-mixture from the last vessel is washed with fresh water to remove monobasic acids formed during the oxidation, the washing-water is separated from the oxidation-mixture, the washing-water is then used, wholly or partly, for washing the intermediate oxidation-mixture from each of the preceding oxidation-stages, and the final oxidation-mixture is submitted to distillation, for the separation of the unreacted cycloaliphatic hydro-carbon and the individual oxidation products. The oxidation-mixture is preferably washed with aqueous alkali hydroxide or carbonate solution before the distillation. Organic acids can be recovered from the washing-water and from the aqueous alkaline solution.  The process may be used for the oxidation of cyclohexane in order to produce cyclohexanone and cyclohexanol; it may also be used for the oxidation of methyl-cyclohexane and cyclooctane.  The oxidation is advantageously carried out at a temperature of 130 DEG -150 DEG C., a pressure of 3 to 30 atm., and in the presence of an oxidation-catalyst, such as cobalt naphthenate. The gaseous and vaporous constituents of the intermediate oxidation-mixtures are preferably subjected to water-washing together with the liquid constituents; the gaseous streams are then combined and cooled to recover unreacted cycloaliphatic hydrocarbon.  The gaseous stream is finally washed with the liquid oxidationproduct, i.e., the final oxidation-mixture from which the unchanged hydrocarbon has been removed by distillation.  Specification 776,803 is referred to.

Title: Process of manufacturing electrically heated devices
IPC: H05B3/40
Filed: 1957-08-19
Abstract: 846,310. Making electrically heated devices; stamping; working at specified temperatures. SUNBEAM CORPORATION. Aug. 19, 1957 [Nov. 19, 1956], No. 26154/57. Classes 83 (2) and 83 (4). [Also in Group XI] In a method of making an electrically heated device a pattern of weld-preventing material is placed between a pair of superimposed metallic sheets, the sheets are welded together and the areas covered by weld-preventing material are expanded by fluid pressure to form a passageway in the composite welded sheet, a flexible electric heating element being inserted in the passageway. Sheets 21a and 21b of two different aluminium alloys are degreased, deoxidized and secured together by welding or crimping the edges, a pattern of stop-weld consisting of graphite and waterglass having been included between. The stop-weld may be applied by using a masking die or a stencil or may be squeezed through a silk screen. The sheets are then first hot-rolled in a reducing atmosphere at a temperature of approximately 1000‹ F., e.g. 925‹-950‹ F. to pressure weld them and form a unitary sheet, then cold-rolled to gauge and annealed at 660‹ F. The unbonded areas are then inflated by water under pressure the passageways 33a, 33b, 33c, 33d being formed by expansion of the sheet 21b only into the die 32, the die 31 having a plane face. After steamcleaning the passageways the branch 33d is closed by rolling. Several unitary blanks may be simultaneously made by bonding and inflating two large sheets having a number of separate stop weld patterns between. Heating elements 36 consisting of a resistor wound on a glass fibre core and covered by glass fibre insulation are mounted in the passageways 33a and 33b prior to or after the deep-drawing of the unitary sheet to form the container 21 of an electric frying pan 20. If the elements are in the passageways during the deep-drawing the metal is pressed into contact with the elements. One of the projecting ends of the heating elements which are in series is connected to a conductor 51 mounted in the handle 22 which is attached to a watertight housing 40 welded to the body of the pan. The handle 22 is adapted to receive a power lead in its remote end to which the conductor 51 and a slidable rod 45 operated by a control knob are attached. The other end of the heating element is attached through a switch 42 operated by a bi-metal thermostat 46 to the rod 45. In a modification the housing may be detachably secured by screws which engage tapped lugs welded to the container. The invention may also apply to a coffee maker, egg cooker, saucepan or deep-fat fryer. Specification 810,728 is referred to.
