Title: Method for manufacturing fibre reinforced cement article
IPC: C04B28/04
Filed: 1977-06-13
Abstract: In order to obtain an improved reinforcing effect of the glass fibres in the production of fibre-reinforced cement boards and, furthermore, to reduce the risk of fracture of the boards, it is proposed to prepare a suspension by mixing asbestos, cement and water with stirring. During continued stirring, glass fibres are then added to this suspension, whereupon the board is produced from the resulting suspension. The raw material comprises preferably 5 to 20% by weight of asbestos, 0 to 12% by weight of cellulosic material, the total amount of asbestos and cellulosic material being more than 10% by weight, and 0.2 to 4% by weight of glass fibres and the remainder cement.

Title: Improved construction of appliance for taking foot measurements for boots and shoes
IPC: A43D1/02
Filed: 1925-10-05
Abstract: 261,518. Robinson, A. P. Oct. 5, 1925. Printing finger and other skin impressions: inkless printing by chemical reaction. - Means for taking impressions, more particularly of the feet, comprises two sheets of absorbent paper or other material treated with materials which react chemically when the sheets are brought together under pressure, producing a visible marking on one of the sheets, the intensity of which corresponds with the intimacy of contact of the sheets. In the treatment of the sheets, one sheet is saturated by dipping or spraying with a solution of an acid reagent, such as gallotannic acid or gallic acid, glycerol being added as a hygroscopic medium if desired. The other sheet is treated with a solution of a salt such as ferric chloride. with the addition of glycerol. After being impregnated uniformly, the sheets are pressed and dried to a predetermined extent. In taking an impression of a foot, the sheets are superposed and the foot is pressed upon the upper sheet, the presence of the hygroscopic medium facilitating the transference of the ferric chloride to react with the gallotannic acid and producing a blue black precipitate of ferric gallotannate. An outline of the foot is obtained' by passing a scriber around the foot while it is resting upon the sheets. As shown in Fig. 3 the sheet A, which is impregnated with gallotannic acid, is marked to indicate whether the impression is of a left or right foot. The impression of the foot thus obtained is measured by means of a transparent scale, Fig. 4, provided with graduations c, e corresponding to standard sizes &c. indicated on charts j, k, the extremity of the heel of the impression being placed upon an index mark a in taking measurements. Transverse graduations may also be provided. The graduations are symmetrical about centre lines d, b to enable measurements of both feet to be taken without reversing the scale. Alternatively, a half of the scale may be disposed on each face of the transparent sheet, respectively to the right and left of the centre line, the sheet being turned over when necessary. According to one of the Provisional Specifications the measuring sheet may be opaque, both sides then being graduated.

Title: Process for the production of ketones from secondary alcohols
Filed: 1952-10-03
Abstract: <PICT:0767093/IV(b)/1> A ketone is obtained by dehydrogenation of the corresponding secondary alcohol in the presence of a dehydrogenation catalyst, the reaction being carried out in the liquid phase in the presence of a substance having a boiling point higher than the boiling point of the alcohol under the pressure employed, a coefficient of adsorption on the catalyst lower than the coefficient of adsorption of the alcohol on the catalyst and which is inert under the conditions of the reaction, and with continuous removal from the reaction mixture, by fractional distillation, of the hydrogen and ketone formed.  Specified inert substances are saturated hydrocarbons, e.g. heavy naphthenic hydrocarbons such as tetradecahydroanthracene, heavy paraffins such as triacontane and naphthenic hydrocarbons having a paraffinic side chain, e.g. hexadecyl decahydronaphthalene; also mixtures of such substances, e.g. those present in tars resulting from the hydrogenation of coal, coal tars or petroleum bottoms.  Specified dehydrogenation catalysts are Raney nickel and Raney copper.  In the Figure the alcohol is introduced at A into the reactor E provided with means for agitation, temperature regulating means and level-regulating means and the catalyst and the insert substance are also introduced into the reactor which has mounted thereon or leads to a rectification apparatus F, e.g. a distillation column.  The ketone vapours are condensed at G and withdrawn at I, hydrogen being withdrawn at M whilst part of the ketone may be returned to the column as reflux. Examples are given for the production of acetone from isopropyl alcohol, methyl ethyl ketone from 2-butanol, and cyclohexanone from cyclohexanol, the reaction being carried out in each case in the presence of Raney nickel as catalyst and of tetradecahydroanthracene as inert substance.
