Title: New dyestuffs of the benzene-monoazo-pyrazolone series and metal complexes thereof and process for their manufacture
IPC: C09B45/14
Filed: 1957-02-18
Abstract: The invention comprises dyes of formula <FORM:0838657/IV(c)/1> where R is a benzene residue free from groups imparting solubility in water bound in the 1-position to the OH group and in the 2-position to the azo link and contains a chlorine and/or a nitro group, R1 is H or an alkyl group or a benzene residue which may contain substituents, and X is a carboxylic acid ester or amide group bound through the CO group to the pyrazolone ring and their 1,2-metal complexes. Preferred are compounds in which R1 is H or a benzene residue and X is <FORM:0838657/IV(c)/2> where n is 1-7 and Y2 is an alkyl, aralkyl, cycloalkyl or aryl group.  Chromium and cobalt are preferred metals. They may be made in conventional fashion by coupling appropriate diazotized amines with the requisite pyrazolones.  Metallization may be effected in substance, on the fibre or in the dyebath. Other preferred classes of dyes are those derived from 6-nitro-2-aminophenols containing 4-chloro- or alkyl substituents and from monosubstituted 2-aminophenols, especially the 4-chloro- and -nitro-derivatives.  Representative of compounds from which X is derived are ethanol, m-cresol, isopropylamine, 11-methoxypropylamine, cyclohexylamine, N-methyl-cyclohexylamine, aniline, benzylamine, dimethylamine, N-ethyl-aniline and morpholine.  The metal complexes dye and print materials such as wool, silk, leather and fibres of polyamides and urethanes.  They dissolve in organic solvents and can be used for colouring lacquers and natural or synthetic resins, e.g. cellulose ethers and esters and for spin dyeing cellulose acetate and poly-amides and -urethanes.  Examples are provided of the preparation of the dyes and the use of chromium and cobalt complexes thereof in colouring nitrocellulose lacquers and dyeing wool.  Red and brown shades are obtained.  Specifications 637,404 and 765,355 are referred to.

IPC: E04B1/04
Filed: 1920-02-24
Abstract: 162,845. Armstrong, J. G. D. Feb. 24, 1920. Walls.-Stud-and-slab buildings are built of precast monolithic reinforced slabs, three courses being employed for a one-storey building and five courses for a two-storey building, such slabs extending from cross wall to cross wall, or from pilaster to pilaster or from window to window, no vertical joint showing on the external wall except at a pilaster or other vertical projection. The slabs are hoisted into position by machinery. Fig. 14 shows a two-storey building having five courses A, B, C, D, E. The slabs and pilasters are jointed by means of grouting poured into holes H and grooves 4, the jointing surfaces having shoulders 1, rebates 2, indents 3 and splays 5, Fig. 5. Door jambs are made of concrete and have a wide rebate on the jamb remote from the hinge to take varying sizes of doors. The slabs are preferably moulded in metal moulds and in the case where different qualities of concrete are used for inner and outer faces, a dividing sheet is placed in the mould and worked up and down to amalgamate the two concretes. The slabs may be solid or have continuous vertical cavities which are closed at window and door openings by covers.

Title: Improvements in or relating to cooling and annealing sheet glass
IPC: C03B25/08
Filed: 1924-03-04
Abstract: 230,261. Wade, H., (Empire Machine Co.). March 4, 1924. Glass annealing leers; tunnel furnaces. - A method of annealing sheet glass comprises supplying streams of gases to the tunnel above and below the glass level adjacent one end of the tunnel, and altering the relative cooling effect of the two streams to obtain a uniform rate of heat loss on both faces of the glass. The apparatus shown in Fig. 1 consists of a tunnel leer 3, having a floor sloping upwards from the entering end 7 to the delivery end 5, which receives a sheet from a flattener 2 with burners (not shown). The flow of gas above and below the sheet, which is propelled on bars 6, is controlled by dampers 9. In modifications, the flow above the glass is lessened by dampers within the leer, by lead-off flues controlled by dampers, or by water-circulated coolers. Both streams may be varied by suction fans, or heat may be added to the lower stream by means of a floor containing a heating flue.
