Title: Manufacture of arsenobenzene-mono-sulphoxylates
IPC: C07F9/74
Filed: 1936-01-22
Abstract: Arsenobenzene - monosulphoxylates of the formula <FORM:0469323/IV/1> in which R and R<1> represent hydroxyalkyl groups, are prepared by condensing di-(hydroxyalkyl) - amino - hydroxybenzene - arsenoxides or arsines with aminohydroxy benzene-arsines or arsenoxides respectively, and treating the resulting arsenobenzenes with sodium formaldehyde-sulphoxylate. Alternatively, the sulphoxylate radicle is introduced into the aminohydroxybenzene-arsine or arsenoxide prior to the condensation.  Both of the foregoing methods may be effected using an arsenoxide or arsine which is not hydroxyalkylated in the amino group and the hydroxyalkyl radicles subsequently introduced. Furthermore, one of the trivalent arsenic compounds used as starting materials may be prepared in situ by reduction of the corresponding arsonic acid.  According to the examples: (1) 3-(bis-dihydroxypropyl)-amino-4-hydroxybenzene-1-arsenoxide is condensed with the reaction product of 3-amino-4-hydroxybenzene - 1 - arsine (see Specification 11625/11, [Class 2 (iii)]) and sodium formaldehyde - sulphoxylate; (2) 3 - amino - 4 - hydroxybenzene-1-arsenoxide is condensed with 3 - aminosulphoxylate - 4 - hydroxybenzene - 1 - arsine and the product treated first with ethylene oxide and then with glycide, each in equimolecular proportions.  The sample furnished under Sect. 2 (5) comprises 3 - (bis - dihydroxypropyl) - amino - 4 - hydroxy - 3<1> - amino - 4<1> - hydroxy - 5<1> - methoxyarsenobenzene-sulphoxylate prepared by reducing a solution of 3-(bis-dihydroxypropyl)amino-4-hydroxybenzene-arsenoxide and 3-amino-4-hydroxy-5-methoxybenzene-1-arsonic acid (see Specification 373,085) in methyl alcoholic hydrochloric acid with stannous chloride and treating the product with sodium formaldehydesulphoxylate.  3 - (Bis - dihydroxypropyl) - amino - 4 - hydroxybenzene-1-arsenoxide is obtained by reducing the corresponding arsonic acid with sulphurous acid and potassium iodide.

Title: Improvements in or relating to photographic processes and materials
Inventor: HADDOCK NORMAN HULTON
IPC: G03C5/44
Filed: 1959-01-21
Abstract: 873,054. Photographic colour processes and materials. ILFORD Ltd. Jan. 21, 1960 [Jan. 21, 1959], No. 2300/59. Class 98(2) An element containing a silver image is treated with a bleach bath in the presence of what is defined as a cobalt phthalocyanine precursor to result in replacement of the image by one of blue or blue-green cobalt phthalocyanine dye. The bleach bath itself is of known type and the precursor, which may be applied in the bath or in the element, is described with reference to Specifications 687,655, 713,459, and especially Specification 759,377. In Example 1 an emulsion coated on film or paper is exposed to a step-wedge, black-andwhite developed, fixed, washed, placed in a bath comprising thiourea, citric acid and anthraquinone-2-sulphonic acid to which a proprietary precursor (Registered Trade Mark) "Phthalogen Blue" 1B in methanolic acetic acid had been added, after which any remaining silver may be removed by treatment in an acid copper sulphate with sodium chloride silver-dye-bleach bath, followed by fixing; and remaining precursor, in particular when using a paper support, may be removed by acetic acid in water with dioxan. Example 2 describes preparation of a dispersion of the precursor in polyvinyl alcohol and addition of this to a silver halide emulsion, treatment of which follows the pattern of Example 1; and Example 3 a transfer process in which a laterally inversed positive silver image is treated in a silver-dye bleach bath and then contacted with duplicating paper coated with a precursor preparation: several copies may thus be made. The phthalocyanine dye images have greater fastness to light than those made by colour development, and the Provisional Specification indicates the use thereof in and for the red-sensitised layer of a conventional multilayer material, and also a meshing procedure for colour correction using a layer with a dye-bleached dye image complementary to the phthalocyanine image. Specifications 397,159, 490,451, 636,222 and 711,247 are referred to.

Abstract: 788,886. Colour television. SYLVANIA ELECTRIC PRODUCTS, Inc. Jan. 24, 1956 [Jan. 24, 1955], No. 2376/56. Class 40 (3). [Also in Group XX] To facilitate correct adjustment of the hue and saturation controls of a colour television receiver, there is located near the image screen 12 a standard source of colour 20 in the form of a series of filters 24 illuminated from the rear by a lamp. The colours chosen correspond to those employed in a standard test pattern transmitted before a programme begins. A further series of grey filters 26, ranging from one hundred per cent transmission on the left to eleven per cent transmission on the right and corresponding to the monochromatic reproduction of the bar pattern produced in the absence of the colour-specifying part of the received signals, is provided to permit the brightness and contrast controls to be correctly set with the saturation control set to zero. A hinged lid 22 covers the filters when not in use. The illumination for the standard source of colour may comprise a conventional incandescent lamp, although since the light intensity will fluctuate with the supply voltage and decrease gradually during life with such a lamp, a fluorescent lamp connected between points of constant voltage, for example in the receiver power supply regulator circuit, is preferred.

Title: Electric pulse modulation signalling systems
IPC: H04B14/02
Filed: 1944-02-11
Abstract: 579,860. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). Feb. 11, 1944, No. 2541. [Classes 40 (iii) and 40 (v)] In a pulse-modulation signalling system in which signals are represented by short impulses, each short impulse is replaced by two or more closely-adjacent impulses in order to prevent false operation of the receiver by interfering impulses. Thus in Fig. 2, the impulse sequence 3a, 3b represents the beginning and 4a, 4b the end of a signal, whereas 9a and 10a represent interference. As shown in Fig. 5, the pulse transmitter 30 supplies short single impulses representing the beginning and end of durationmodulated rectangular pulses. These impulses are applied directly to the grid of a gas-discharge tube 31 and indirectly through a delay network 35 to a similar tube 32, the two closely-adjacent impulses being taken off across a resistance 33 common to their anode circuits. These impulses 13 are received at 14, Fig. 4, and are applied directly to one grid 15, and through a delay network 18 to a second grid 17 of a valve 16. As this valve only passes current when both grids receive an impulse simultaneously, a single impulse 19 appears in the anode circuit and is passed to a double-stability circuit 21 of known type which serves to rebuild the duration-modulated rectangular pulse 22. The closely-adjacent impulses may be three or more in number and one or more of them may be inverted. The transmitter 30 of Fig. 5 may comprise the telegraph keying circuit shown in Fig. 6, in which a sine-wave generator 40 is connected to the grids of two gas-filled tubes 41, 42 the latter connection including a phaseshifting or delay network 44 ... 47. When the key 48 is down and the condenser 46 in circuit, pairs of signals are sent out from the common anode load 51 with an interval corresponding to a mark ; and in the other position of the key, with an interval corresponding to a space. The output of Fig. 6 is utilized as the pulse source 30 of Fig. 5.

Abstract: 1,010,293. Programmed control of machine tools. C. RICHARDS & CO Ltd. Jan. 25, 1962 [Oct. 26, 1960], No. 2782/62. Divided out of 1010291. Drawings to Specification. Heading G3N. In a programme controlled machine tool, four alternative methods of modifying the response to a recorded programme to compensate for changes in cutter radius are described. The machine tool is of the kind in which X and Y pulse phase modulated command signals (from a record) are compared with similarly modulated signals derived from moirÚ fringe tool slide position detectors. In all cases, the X axis compensation is r sin # and Y axis compensation is r cos #, where # is the angle between the radius reactor and the Y axis, and r is the difference in radius between the nominal cutter and the actual cutter. In the first embodiment Fig. 2 (now shown) the leading edges of the pulses are phase modulated in accordance with the command signal and the trailing edges in accordance with the compensation signal, the values being computed, r being made large enough to cover all likely variations. The required portion of this signal is selected manually Fig. 4 (not shown) at the machine tool according to the particular amount of compensation required, and the sense can be reversed according to whether the cutter is over or under size. In a modification, Fig. 3 (not shown) the command and compensation signals are again combined, Cut the compensation signal is derived from a resolver driven by the curve following, command signal generator. In another embodiment, Fig. 6 (not shown) the compensation components are recorded, over size and under size separately, X and Y separately, on 4 auxiliary tracks and the desired amount of compensation is selected at the machine tool Fig. 5 (not shown). In the fourth embodiment, values of the angle # are recorded, and the required sine and cosine components are computed at the machine tool.

Title: Vulcanisable organopolysiloxane compositions
IPC: C08L83/04
Filed: 1959-01-26
Abstract: Liquid compositions which are moisture-free, vulcanisable in the presence of water and which are stable in storage, comprise a linear siloxane of the formula R2SiO, in which R is a hydrocarbon radical, and containing at least 0,1% Si-bonded OH groups, and from 0,5 to 25% (by weight of the siloxane) of an organotriacyloxysilane of the formula R 1Si(OCOR11)3 wherein R1 is a lower alkyl, alkenyl, aryl or aralkyl radical and R11 is an alkyl group of 1 to 18 C atoms or an aryl group.  Moisture-free loading agents of fillers, e.g. ZnO, CdO, CaCO3, SiO2, diatomaceous earth and iron oxide, and solvents, e.g. toluene and xylene, may also be added.  In application the compositions are simply spread in layers, poured into a mould or profiled by means of a trace press, and then subjected, e.g. to contact with a moist atmosphere.  In a typical Example (1) a dimethylsiloxane oil, containing 0,15% by weight of SiOH groups and obtained by heating the cyclic tetramer with aqueous KOH-, was mixed with methyltriacetoxysilane in an apparatus fitted with a stirrer, and agitated under an atmosphere of dry nitrogen until a translucent liquid was obtained; a portion of this liquid was cast on a glass plate and formed a film after 5 hours in the ambient air at 20  DEG C.  Uses: for sticking various materials together, e.g. silicone rubber, phenol-formaldehyde resins, brickwork, wood and glass; for caulking, coating glass fabrics, protecting supports, covering articles and producing films and moulded articles.
