Patent GB-1008805-A (GB)
Title: Finely-dispersed dyestuff preparations
IPC: A61K35/32
Filed: 1962-07-27
Abstract: Finely dispersable dyestuffs and pigments are obtained by precipitating the dyestuffs and pigments in a liquid medium and in an ultrasonic field.  The dyestuffs and pigments may be precipitated from solutions thereof using a precipitating liquid or from the reaction media in which they are formed by mixing solutions of the reactants.  The dyestuff or pigment solution and the precipitating liquid or the solutions of reactants may be simultaneously run into a reaction chamber by entry pipes whose openings are directed towards one another and lie in the maximum of the sound energy from a source of ultrasonic waves.  In examples, the hydrocarbazoles of 4: 41 - dibenzoylamino 1 1: 11-dianthrimide and 4: 51 - dibenzoylamino - 1:11-dianthrimide in sulphuric acid solution are each precipitated by mixing with water in an ultrasonic field and the products are oxidized to the corresponding carbazoles with dichromate; (3) the hydrocarbazole of 4:41-dibenzoylamino-1:11 -dianthrimide in sulphuric acid is precipitated in an ultrasonic field using water containing dichromate to give the carbazole direct; and (4) an alkaline solution of acetoacetanilide was mixed with a solution of diazotized 3-nitro-4-toluidine in an ultrasonic field to give the monoazo dye Hansa Yellow G.

[Also in Group XXII] A method of wiring electrical circuit panels comprises placing an insulated wire in crossing relating with a wire previously attached to the panel, and pressing the wire through a hole in the board to form a loop on the other side. The loop is then subsequently compressed, coincidentally crushing the insulation which may then subsequently be removed by brushing. The panel 1 is attached to a slide (not shown) adapted to move horizontally in any direction, and a wire 7 to be positioned is raised above the panel by the head 8 carrying a reel of wire 9. The slide is moved to bring one of the holes 11 under the head and the head rotated to the desired direction and brought down on to the panel. A spring-operated plunger 12 (Fig. 2) forces the wire through the hole 11, and is thereafter slightly raised. The punch 15 is then pressed against the loop to compress it and crush the insulation. A knife 17 guided within the head may then be operated to cut off one end of the wire.

Abstract: A non-smoking solid fuel comprises a consolidated mixture of expanded, finely divided carbon and a non-smoking non-bituminous organic binder, said carbon having an as-produced bulk density of 6-20 pounds/cu. ft., a volatile content of 3-18% and a particle size of 5-1000 microns and being produced by the flash calcination of carbonaceous particles at 1150-2000 DEG  F. in a gas stream containing 2.0-5.0 s. cu. ft. of oxygen/lb. of carbonaceous material, said carbonaceous particles having a volatile content of 23-45%, which although normally solid at ordinary temperatures are capable or becoming plastic and expanding on heating.  Carbonaceous particles having a volatile content of 14-45% and a particle size of at least 75%-100 mesh (U.S. Standard) may be employed by heating for 3-30 seconds in a downward, linear flow, vertical reactor while the particles are moving at 7-0.7 ft./second through a reactor maintained at 1150-2000 DEG  F. in a gas containing 2.0-5.0 s. cu. ft. of oxygen/lb. of carbonaceous particles so that at least 10% of the evolved combustible volatile matter remains unburned, the particles being flashcalcined at a rate in excess of 2000 DEG  F. per second. The finely divided carbon may be formed into briquets by mixing with water, an ignition agent and the organic binder, densifying the loose carbon either before or during the mixing to increase the bulk density, roll briquetting the mixture at a temperature no higher than 130 DEG  F. and drying the resulting briquets.  Ignition agents specified are sodium carbonate, alkali metal nitrates, chlorates, or chlorides, copper, lead or sodium oxides or mixtures thereof.  Corn starch is the specified binder. Lime, borax and hickory sawdust may be included in the briquets which may be coated with a water solution of starch. Specification 786,207 also is referred to.
