Title: Improvements in or relating to detergent compositions
Inventor: FRASER JULIAN PAUL
IPC: C11D1/00
Filed: 1949-08-05
Abstract: The dimethylamine salt of cetyl hydrogen sulphate is prepared by refluxing a methyl alcohol solution of an aqueous paste of the sodium salt of cetyl hydrogen sulphate with an aqueous solution of dimethylamine sulphate.  Anhydrous dimethylamine salt of cetyl hydrogen sulphate is isolated from the reaction mixture (a) by filtering and then distilling first at atmospheric pressure and finally under vacuum, or (b) by-flash distillation to remove most of the methanol and then settling so that an upper layer of the molten anhydrous dimethylamine salt of cetyl hydrogen sulphate separates.ALSO:A composition whose dispersion in water is fine enough to appear homogeneous to the naked eye, has a pH of 5-7 and has detergent properties in presence of alkali, comprises a solution of a minor proportion of a salt, which is an anionic surface-active agent, in one or more soap-forming fatty acids, both the salt and the fatty acid being sufficiently free of water to yield, when fused together and cooled, a single-phase composition.  Suitable anionic surface-active agents are water-soluble salts of organic bases, particularly salts of dimethylamine, diethylamine or trimethylamine with alkyl hydrogen sulphates, alkyl sulphonic acids, aralkyl sulphonic acids or alkyl- or aralkyl-substituted hydroxy- or amino-alkane sulphonic acids.  The alkali metal salts of organic sulphuric acids or of sulphuric acid esters in which the sulphonic acid radicle or the hydrogen sulphate radicle is attached to a secondary carbon atom and the hydrocarbon radicle comprises 9-18 carbon atoms may also be employed as well as alkali metal salts of dialkyl esters of sulphosuccinic acid.  Dispersions in water of the composition may be employed, in presence of alkali, for laundering textile goods.  In an example, a mass of mixed fatty acids prepared from beef tallow, palm oil and arachis oil, and having a titre of 37-38 DEG C, is melted and into it is introduced 2 per cent of the dimethylamine salt of cetyl hydrogen sulphate, (see Group IV(b) for preparation) or the sodium sale of the dioctyl ester of sulphosuccinic acid, (prepared as described below).  An aqueous solution of sodium metasilicate may be added to a water dispersion of the resulting composition and the liquid thus obtained used in a laundry washing machine.  Preparation of the anhydrous sodium salt of the dioctyl esters of sulphosuccinic acid.-Ethyl alcohol and benzene are added to an aqueous solution of the sodium salt of the dioctyl ester of sulphosuccinic acid and water is removed by azeotropic distillation, leaving an alcoholic solution of the sodium salt as residue.  The alcohol is then evaporated off.

Abstract: 777,657. Variable high-frequency attenuators. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 18, 1955 [July 20, 1954], No. 20711/55. Class 40 (8). A variable push-button attenuator for frequencies within the megacycle range comprises a number of attenuator sections each associated with a switch, the switches being in the form of displaceable links which form parts of the inner conductor of a coaxial line having a characteristic impedance equal to the input and output impedance of the sections. The sections are separated by screening boxes 35 and each consists of two series resistors 1, 3 and a shunt resistor 5 the output line 31 being connected between the free terminal of the last series resistor 3 and the earthy end of the last shunt resistor 5. The parasitic inductance L1 of the resistors '1, 3 may be compensated by shunt capacitors 29 of value C 2  given by: The sections are connected in series by movable bridges 7, Fig. 4 (a rear view), which provide conductive paths between the terminals 53 of resistors 1, 3 in adjacent sections. The bridges 7 are mounted on insulating push rods 15. Each resistor 1 is provided with a contact 25 extending through the outer conductor 27 of a coaxial line to which an input line 33 is connected. The inner conductor of the coaxial line is of square section and comprises fixed portions 9 and movable L-shaped portions 11 mounted on the ends of axially movable insulating rods 41. These rods are resiliently coupled to the push rods 15 by forks 43 mounted between helical springs 45, 47. Depression of a push rod 15 breaks the coaxial line and connects the righthand (input) portion of the line to the resistor 1 of an attenuator section. At the same time, displacement of the corresponding bridge 7 breaks the connection between the resistor 1 and the resistor 3 in the adjacent section leaving in circuit the sections which lie between the displaced bridge and the output 31. Another arrangement is described in which the input and output are arranged at opposite ends of the apparatus. Specification 644,066 is referred to.

Title: Photographic copying apparatus
IPC: B41B23/00
Filed: 1952-08-18
Abstract: 707,850. Photographic copying apparatus. HIGONNET, R. A. E., and MOYROUD, L. M. Aug. 18, 1952, No. 20723/52. Classes 98(1) and 98(2) Apparatus for composing images upon a photosensitive surface comprises a support for the said photosensitive surface, a support for a first imagecarrier, a support for a second image-carrier, a partial reflector adapted to reflect images from the first carrier and to transmit images from the second carrier, and an optical system for projecting the reflected and transmitted images on to the photosensitive surface. As shown in Fig. 1, a pedestal 6 in a casing 2 supports a block 4 comprising two right-angled prisms having a partially silvered contact face 18. Lens 8, 10 are mounted near the block so that an image of a film 12 bearing letterpress can be projected through the block on to photographic film 16, and an image of a film 14 can be projected by reflection at the surface 18 on to the film 16. A container 28 for film 16 has a dark slide 30 and is removable from the casing. It is mounted in front of a tapered light-tight tunnel 26 which is closed by a shutter 22, operated by a rod 24 to make an exposure. Images of films 12, 14 are also projected on to a ground glass screen 20. Film 12 bears original text, while film 14 bears lines of corrected text to be substituted for defective lines in the original. Each film is mounted in a lighttight box 56, Fig. 2, having an apertured base 48, and suspended before an aperture 44 in casing 2 by hooks 46 which engage rebates formed in a rack 42. Pinions 50 are mounted in the hooks to engage the rack teeth and move the box laterally when knobs 52 are turned. Shutters 58, 60 are movable in front of the film by a rack-and-pinion. The projection lamps 74 are mounted behind the film, and are of variable intensity. When lines of the original are to be replaced, part of film 12 is unmasked to project an image of the page down to the incorrect lines on to screen 20. Part of film 14 is also unmasked to project the correct lines under the image of film 12. The images are lined up on the screen by the adjustments provided. To facilitate adjustment + and - marks are printed at the beginning and end of each line. Since the reflecting surface transmits more light than it reflects, and the lamps are adjusted to produce equally intense images on film 16, the image of film 14 on screen 20 is brighter than the image of film 12. Other matter, such as pictures, can be projected from positions 32, 34 by means of mirrors 36, 38 which are turned when required to reflect light from these objects into the optical system. From single columns of text a double-column page form can be printed, with tables &c. of the full width of the page. Specification 669,531 is referred to.
