    Abstract: 968,111. Fire alarms. J. STEVENSON. Nov. 16,1961 [Sept. 28,1961], No. 34877/61. Heading G4N. A fire alarm device comprises the combination in a ventilated holder 15 of a dry cell battery 3, a bell or the warning element (such as a lamp or buzzer) 5 and a thermostat switch 9 which is normally open but is adjusted to close whenever the ambient temperature exceeds a preselected figure and reopens when the temperature falls below that figure; these elements being wired together so that closing of the switch energizes the warning element. A push button switch 7 is connected across the thermostat switch to allow the operation of the battery and bell to be tested.

    Abstract: 614,004. Vehicle bodies. HUMBER, Ltd., MILLER, A. C., OLIVER, W. T., and STEVENSON, L. J. Feb. 13, 1946, No. 4546. [Class 108 (i)] A motor vehicle has a body constructed by superimposing sheet metal panelling, plastic material or the like, upon a framework of tubular or other section material welded together and so shaped to provide supports 1 for a bonnet, a mounting for a windscreen 3 and 4 and an engine compartment 16 and 17 at the rear. The body framework has eight screw-threaded spigots 19, at the ends of tubes 1, 5, 12 and 13, which in combination with nuts 20 and rubber washers 21 provide a flexible attachment to the chassis. The chassis provides a flat platform of pressed steel on which the passenger seats may be mounted and which is sufficiently strong to take the whole of the load and road shocks, the body serving only to protect and/or constrain the load.

[Class 18] A container for fragile articles such as glassware or ceramic ware is provided with a set of compartments as shown, formed from a single blank of elongated rectangular shape folded to form a series of compartments closed at the bottom D and subdivided by partitions A. Several such sets of compartments may be positioned in a container by loose blocks, the container having one open end. Extensions from the walls D may form additional walls for the main compartments.

    Abstract: 333,236. Wilson, J. S., Beckett, E. G., Thomas, J., and Scottish Dyes, Ltd. Feb. 2, 1929. Dye preparations. - Dry powders of anthraquinone acetyl silk dyestuffs are prepared by mixing the dyes in the form of aqueous paste with alkali soaps of higher fatty acids and subsequently drying at temperatures not higher than 50‹. Other dispersing or solubilizing agents may be admixed either during or after the above process. According to examples, (1) a paste of Duranol Blue CB is mixed with a neutral soap and dried at a low temperature, (2) a paste of Duranol Orange G is mixed with an alkaline soap, dried in vacuo at 50‹ C., powdered and ground, and (3) a paste of Duranol Red 2B is mixed with dry soap and soda ash, and dried, either in vacuo or in a stream of air, at 50‹ C. Both ordinary and dispersed pastes, containing saponin, sulphite cellulose waste liquor, formaldehyde-naphthalenesulphonic acid condensation products, or naphthalene sulphonic acids may be used. Specifications 211,720, [Class 15 (ii), Dyeing, Processes &c. for], 219,349 and 224,925 are referred to.

    Abstract: Viscose solutions to be used for the manufacture of artificial silk are freed from undissolved particles by subjection to centrifugal separation as described in Specification 203,074, followed by filtration through charcoal or a mixture of charcoal and sand. The solution is preferably cooled to 0-3 DEG C. before filtration.

    Abstract: 138,507. Thomson, J. S. April 29, 1919. Man-hole covers.-Consists in forming an elliptical man-hole door A with a lip D to engage with the back edge of the reinforcing-ring E of the man-hole, and with hollow screwed bosses F to receive the securing-bolts G, the whole being arranged so that no part of the door or its fasten. ings projects beyond the level of the plating C. The heads H of the bolts are circular and enlarged to engage the front edge of the ring E. They may be cut away as at M, Fig. 1, so that the door may be removed without fully unscrewing the bolts, in which case the bolt head is formed with a wedge-shaped underside, as at N. A lifting bolt P, or eye-bolt, is located in a central depression R in the cover. The cover may be dished in various ways, so that the outer face B instead of being flush with the plate C is in the rear thereof.

    Abstract: Non-inflammable films or filaments for kinematographs, lining projectiles, &c. are made by mixing substantially equal amounts of triacetin and triphenylphosphate with a solution of acetyl-cellulose, the said amounts being from 10-30 per cent of the weight of acetyl-cellulose. The acetyl-cellulose is first thoroughly dried and is then kneaded with a solvent such as tetrachlorethane, or benzyl alcohol. Specification 130,029 is referred to. The Provisional Specification states also that the product may be used for preserving explosives in filament form.

    Abstract: Textile printing pastes contain as an ingredient a quaternary base compound of the general formula NR R R R x where R , R , R and R are the same or different alkyl or aralkyl groups, one at least of which contains an unsubstituted hydroxy group and where x represents OH or a simple mineral acid residue, such as Cl or SO4R (R being hydrogen, metal, ammonium or substituted ammonium). Even fixation of the colour present is effected by the presence of such substances which are preferably non-volatile or substantially non-volatile, and which are strong bases or salts thereof possessing hygroscopic properties. Choline chloride is specified as a suitable substance, and printing pastes containing vat dyes such as 3.3 -dichloro-dianthraquinone-1.2 : 2 .1 -dihydroazine, Caledon Brown RS, or Durindone Pink FFS are improved by such additions. In an example cotton cloth is printed with a paste of 3 : 3 - dichloro - dianthraquinone - 1.2 : 2 .1 -dihydroazine, British gum thickening, glycerine, Rongalite C, potash and choline chloride, and after drying is steamed. It is stated that the quaternary ammonium compounds employed in the process are not adapted for the production of discharge effects by alkylation or aralkylation of leuco vat colours.

    Abstract: 332,232. Wilson, J. S., Hooley, L. J., Thomas, J., and Scottish Dyes, Ltd. Jan. 16, 1929. Sulphonic acids of vat dyes; dye preparations. -Sulphonic acids of vat dyes for dyeing animal fibres by a vatting process are made by direct sulphonation of the dyestuffs, or by replacement of halogen atoms by treatment with sulphite, as described in Specification 332,249. The sulphonic acids may be employed in the form of pastes or powders obtained by concentrating the solutions of the leuco bodies in the presence of molasses, reducing sugars, sulphite cellulose liquor, lignine sulphonic acid, starch or the like, to which alkalies, such as sodium carbonate, or reducing agents, such as sodium hydrosulphite, with or without other dyeing assistants, solubilizing agents or soaps, may be added. In examples, sulphonic acids are obtained by sulphonating Caledon red BN and Caledon brilliant purple RR with oleum. The products obtained by treating halogenated vat dyes, such as Caledon brilliant purple RR and chlorinated pyranthrone, with soluble sulphites, are also referred to.
