Title: Improvements in and connected with the manufacture of surfaces for multi-colour printing
IPC: C04B28/26
Filed: 1934-10-23
Abstract: 434,514. Photo-mechanical printing- surfaces. MEERE, M. C., 61, Belmore Road, Randwick, and HACKETT, W. H., 32, Leeton Avenue, Coogee, both near Sydney, Australia. Oct. 23, 1934, No. 30378. Drawings to Specification. [Class 98 (ii)] Surfaces for multicolour printing are prepared by making an outline drawing indicating the colour components of the original, transferring this drawing to a soft impressionable smooth surface, stippling this surface, " painting-in " selected portions of this surface to form a representation of a colour component of the original, and from this preparing by a line-block process a photographic reproduction in reduced size on a surface, as of metal, to form the ultimate printing surface. The process is then repeated for the other colour components. In carrying out the process a set of outline or " key " impressions in a colour, such as light blue, which will not be photographed are produced on smooth coated drawing boards, which are then given a stippled surface by means of a die. The areas corresponding to a particular colour are then lined in with black chalk or ink or given a black wash all over and the unwanted parts scraped away, and the resulting picture is photographed on a reduced scale, the reduction serving as a negative for producing a printing surface by known methods. Specifications 26023/12, [Class 98 (ii)], and 412,441 are referred to.

Patent GB-340633-A (GB)
Title: The manufacture of vat dyestuffs of the anthraquinone series
IPC: C09B1/00
Filed: 1929-10-08
Abstract: Anthraquinone oxazoles.-A diaryl-o-dioxydiamine containing in each aryl group hydroxy and amino groups in oposition to one another, is condensed with anthraquinone-2-aldehyde or the o -dichloro or o trichloro-2-methylanthraquinone or anthraquinone-2-carboxylic acid chloride.  Condensation is effected at high temperatures, advantageously in a diluent and with or without salts acting as condensing agents, or by treatment with acid condensing agents such as sulphuric acid or zinc chloride.  When anthraquinone-2-aldehyde is employed intermediate formation of azomethines takes place.  In examples a dioxazole derivative is obtained from anthraquinone-2-aldehyde and 3.31-dioxybenzidine by condensation in nitrobenzene in presence of potassium carbonate, or by heating the intermediately formed azomethine under these conditions, or by replacing the 2-aldehyde derivative by the 2-carboxylic acid chloride; it dyes yellowish-orange shades from the vat.

Patent GB-226570-A (GB)
Title: Improvements in and relating to automatic arc welding control systems
IPC: B23K9/073
Filed: 1924-12-20
Abstract: 226,570. British Thomson-Houston Co., Ltd., (Assignees of Clarkson, W. B.). Dec. 22, 1923, [Convention date]. Heating systems.-A reversible motor 5 is used to feed a welding pencil 2 into contact with the work 1, then to withdraw the pencil to strike the arc and afterwards to feed the pencil towards the work to maintain the arc, dynamic braking of the motor being effected at the end of the welding operation. The are is supplied from brushes 10, 11 of a generator 9 designed so that the voltage across these brushes varies in accordance with the welding current and the control circuits are supplied from brushes 10, 12 across which is a substantially constant voltage. Momentary closure of a push 20 operates a contactor x1, closing a main switch 8, a contact 1<b> to complete a hold-in circuit, and a contact 1<c> to complete a circuit through the motor field 5<1>, another circuit being completed from positive main 6, contact 2<b>, armature 5, contact 2<c>, resistor 22, contact 1<a> to brush 12. The motor feeds the pencil 2 into contact with the work 1 whereupon current flows in coil 16 of contactor x2 which lifts and reverses the motor, the armature circuit being main 6, contact 2<c>, armature 5, contact 3<b>, contact 2<b>, and brush 12. Contactor x2 also closes a circuit through contact 2a and coil 17 of contactor x3, but coil 17 is shorted by the contact of the pencil 2 and the work 1. When the motor has withdrawn the pencil sufficiently, contactor x3 lifts and connects the motor for forward motion again, the armature circuit being main 6, contact 3<b>, armature 5, contact 3a to negative main 7. As the voltage across the arc varies with the length, and the armature 5 is now subjected to this varying voltage, the feeding speed of the motor varies automatically with the length of arc. Should the arc break, contactor x2 falls with consequential fall of contactor x3 and the striking operation is repeated. During the striking operation a resistor 21 is shunted across the armature 5, but this shunt circuit is broken at contact 3a when contactor x3 lifts. Momentary opening of a push 19 interrupts the hold-on circuit of contactor x1, which, consequently opens all its contacts and stops the welding operation. Fall of contactors x2, x3 reinserts resistor 21 across the motor 5 to complete a dynamic braking circuit, and as long as there is sufficient voltage across the armature a contactor x4 is held up so as to maintain the excitation of the field 5<1> to cause a strong braking action. In a modification the generator 9 is replaced by a two-brush constant voltage machine and a stabilizing resistance is placed in series with the negative main, the control circuits being connected to the negative brush of the generator and the coil 16 being if desired connected in shunt to the stabilizing resistance. Specifications 139,919, [Class 39 (iii), Heating by electricity] ; and 159,374, [Class 35, Dynamo-electric generators &c.], are referred to.

Abstract: Siloxanes of the unit formula <FORM:0882094/IV (a)/1> wherein Z is an alkali metalloxy radical (MO-) from an alkali metal hydroxide, chlorine or an alkoxy, hydroxyalkoxy or aryloxy radical, each R1 is an alkyl or aryl radical, a is an integer from 2 to 10 inclusive, and b is 0, 1 or 2, are made by admixing a cyanoalkyl siloxane of the unit formula <FORM:0882094/IV (a)/2> or a silane of the formula <FORM:0882094/IV (a)/3> wherein c is 0, 1 or 2, X is an alkoxy radical or halogen atom, and R1, a and b have the above meanings, with an aqueous alkali metal hydroxide, causing complete hydrolysis of the silane or siloxane, and treating the hydrolyzate to recover the desired siloxane.  The cyanoalkyl starting materials are described and claimed in Specifications 797,792, 847,801, 847,802, 847,803, 847,805, 847,806, 847,864, 855,703 and 855,824.  The hydrolysis is preferably effected at 100 DEG C. and in the presence of a mutual solvent for the organisilicon compound and water.  The polymeric alkali metal salts may be neutralized with a mineral acid, e.g. HCl, to yield the free acid polymers which may be reacted with (i) an inorganic acid chloride, e.g. SOCl2 to give the corresponding siloxane acid chloride, or (ii) an aliphatic alcohol, e.g. methanol, propanol or butanol, or a glycol, to give the corresponding carboalkoxysiloxanes.  The functional siloxanes may be copolymerized in known manner with other siloxanes (which may contain unsaturated aliphatic radicals), including endblocking siloxanes.  Examples are given describing the above preparation of the functional siloxanes which can be used to make (vi) polyester resins, and (viii) silicone rubbers, by compounding with a silica filler and benzoyl peroxide and curing. The products also find use in modifying silicones and organic resins, e.g. the carboxyfunctional siloxanes may be esterified or transesterified with aliphatic primary, secondary or tertiary alcohols, hydroxy-terminated polypropylene or polyethylene oxide polymers or phenols in the presence of an acid esterification catalyst.  Examples describe the preparation of (b) bis-(trimethylsiloxy) - g  - carboxypropylmethylsilane and bis-(trimethylsiloxy)-bis-(g -carboxypropylmethyl)-disiloxane; (4, 5) g -carboxypropylmethylsiloxane cyclic tetramer and (3) the acyl chloride and (11, 12) the butoxypolypropyleneglycol ester thereof.
