Abstract: Coating compositions comprise a film-forming agent together with the manganese salt of a dyestuff of the formula <FORM:0693598/IV (a)/1> (X=chlorine, bromine, iodine or nitro) as pigment.  The film-forming agent may be an alkyd, phenol-formaldehyde or other synthetic resin or a cellulose derivative such as the nitrate. Metallic powders such as aluminium may be added.  In examples, the following compositions are described: (1) pigment, drying oil modified alkyd resin, petroleum spirit, lead and cobalt naphthenates; (2) as (1) containing also aluminium pasted with hydrocarbons; (3) pigment, cellulose nitrate, alkyd resin, dibutyl phthalate, blown castor oil, ethyl and butyl alcohols and acetates, and toluene, with or without aluminium paste; (4) cellulose nitrate, polybutyl methacrylate, dibutyl phthalate, castor oil, pigment, aluminium flake and usual esters, ketones, alcohols and hydrocarbons used in lacquers.  Alternative plasticizers are dioctyl phthalate, dicyclohexyl phthalate, dibenzyl adipate, dibenzyl sebacate and benzyl butyl phthalate. Other lamellar or powdered pigments may be used, e.g. copper bronze, stainless steel, nickel, mica, graphite or Pearl Essence. Polybutyl methacrylate may be replaced by its copolymer with acrylonitrile or by other methacrylates, e.g. polymethyl, ethyl, propyl, isobutyl or cyclohexyl.  In the case of polymethyl methacrylate the cellulose nitrate may be omitted.  When an alkyd resin is used it may be modified with a melamine or urea, formaldehyde condensate. Specification 499,790 is referred to.ALSO:The invention comprises the manganese salts of dyestuffs of the formula <FORM:0693598/IV (c)/1> where X is halogen or a nitro group.

Abstract: 567,762. Road - traffic signals. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and RIDDLE, H. J. N. June 25,1943, No. 10303. Drawings to Specification. [Class 118 (ii)] In a vehicle-actuated road traffic control system there is provided a controller having a large number of terminals, of which selected pairs may be strapped or unstrapped as desired to enable the controller, without further modification, to deal with any type of control or to vary the control exercised in any particutar type. This permits a standard controller to be provided at any junction or intersection to be controlled, the control being exercised by connecting up only those parts necessary for the particular control desired, thereby reducing the number of spares of specially designed controllers which it is otherwise desirable to keep. Details of the complete layout and of the various controls possible are described and in particular it is shown how the controller will function as a wholly vehicle-operated device for straightforward operation with three phases A, B, C on A, B, C, A rotation, for operation on A, B, A, C rotation, for allowing two or more phases during part of the cycle and fewer phases for the remainder, for fixed overlapping red, for suppressible overlapping red or extensible overlapping red, and for early out off and/or late start. The controller may also operate as a fixed time cycle or be operated by hand. Provision is made for the controller to function as an independent controller at any intersection or junction or it may serve as a local unit in a master control system and in the latter case the necessary additional control apparatus may be jacked into the controller which may provide for " Prevent " and " Privilege " periods and for " Prevent Bias '' or " Split Phase " progressive working. Specifications 534,026, 534,027, 565,970, and 567,761 are referred to, and the Provisional Specification refers to Specification 519,024.
Patent GB-457878-A (GB)
Title: Improvement in pencil or crayon rod and binder therefor
IPC: B43K19/00
Filed: 1935-04-03
Abstract: A cellulose ether composition which may be used as a binding medium for pigments in the production of pencils or crayons comprises a mixture of two or more cellulose ethers containing two or more different ether groups or different proportions of the same ether group, a portion of the mixture being soluble in water and a portion being insoluble or sparingly soluble in water, the mixture being prepared in such manner that the insoluble portion forms particles of a stringy nature distributed in the soluble portion.  Alternatively, the composition may comprise a mixed cellulose ether prepared in such manner that the product contains a component soluble in water and a component insoluble or sparingly soluble in water and forming particles of a stringy nature.  The composition may consist largely of cellulose dimethyl ethyl ether mixed with other ethers of cellulose of lower methyl content.  In an example, alkali cellulose is shredded and mixed with caustic soda and then heated under pressure with a mixture of methyl and ethyl chlorides or in an open vessel with a mixture of methyl and ethyl sulphates, the proportions being such that the product consists chiefly of dimethyl ethyl cellulose.  The product, on treatment with water forms a viscous mass with stringy particles distributed therein.  These particles may be cellulose ethers containing more than two ethyl radicals or cellulose which is substantially unetherified, or mixtures of several different cellulose ethers formed at the same time as the dimethyl ethyl cellulose which is water soluble.  In a similar manner compositions containing a methyl phenyl cellulose as chief constituent together with insoluble constituents forming particles of a stringy nature may be obtained by treating cellulose with a mixture of etherifying agents.  In the production of crayons the mixture of cellulose ethers is soaked in water and then mixed with a mixture of a filler such as china clay, a pigment such as Milori blue, stearic acid, and calcium stearate.  The mixture is ground, compressed, kneaded, and pressed through dies to form a rod. During this operation the stringy particles in the binder become orientated longitudinally of the rod. The rods are dried, and cut to size.  They may then be heated and soaked in melted wax such as a mixture of carnauba wax and stearic acid.  After cooling they may be glued to wooden sheaths.

Hydrocarbons, cracking; separate heater and evaporator apparatus.-In a process for cracking oils by passing them through a series of tubes heated to cracking temperature, the furnace gases being also used to superheat steam for the cracking operation, the oils are passed quickly through the tubes to avoid appreciable cracking, and the volume and temperature of the furnace gases are such that, the gases pass into contact with the steam superheating tubes at a temperature little below the maximum at which they may safely contact with these tubes. The gases preferably leave the oil-containing tubes at about 1500‹ F. and are utilized for superheating steam to about 900‹ F. The furnace is of the usual two chamber type divided by a wall C. The heating tubes are situated in the chamber A<2> and comprise a series of tubes D, the oil first passing serially through the tubes in the lowest row, and then passing to the next row, and finally leaving through an outlet D<2> and passing through a tube E<3> to a series of tubes E arranged transversely to the partition C in the roof of the furnace, the portions E<1> over the chamber A<2> being encased in metal blocks.
