Title: Saws
IPC: B27B21/08
Filed: 1974-05-24
Abstract: 1460773 Sawing C E SHAW 24 May 1974 23447/74 Heading B5L A pruning or lopping saw having a saw blade 2 with a generally longitudinally extending cutting edge 10 is provided with a saw retaining and blade guiding member 16 pivotally mounted on the blade adjacent, so as to extend generally longitudinally of, said edge so that the blade and guide member are co-operable with each other in the manner of scissor blades, the guiding member being biased by a compression spring 28 towards the blade, and the arrangement being such that in use of the saw the guide member guidingly engages in a kerf pre-cut in a bough on the side remote from the saw and retains the saw on the bough. To prevent saw departure on overstroke, the blade cutting edge and/or the guide member may be curved towards one another, e.g. as shown, the guide member end may be sharply curved towards the blade, preferably at least 45 degrees. The guide member has a flat side parallel and close to the saw blade. The latter is fast (e.g. integral) with a socket 4 receiving, and secured, by a thumb screw 8, to a handle 6. The guide member is pivotable away from the blade, to facilitate placing the blade and guide member about a bough, by means, disposed at the remote end of the handle, acting on the member via a wire 34 and comprising a sliding member or a lever 40 actively pivotable, either towards, or, as shown, away from the handle. In operation, initially the saw is presented to the bough so that the blade is lowermost and a kerf, say “-1/3 bough thickness, is cut; and thereafter the saw is re-presented to the bough with the blade uppermost, and the guide member engaged in said kerf, and the bough sawn through, the pre-cut kerf also serving to avoid the risk of bark tearing.

Title: Improvements in the production and treatment of textile and other materials made of or containing cellulose
IPC: D06M13/256
Filed: 1929-05-31
Abstract: 338,989. Dreyfus, H. May 31, 1929. Divided on 335,894. Yarns &c., treating with liquids.-Artificial filaments, threads, ribbons, films, &c. made of or containing cellulose are subjected to the action of sulphonic acids, containing at least six carbon atoms, of a concentration of 20 per cent or higher and particularly over 30 or 50 per cent. The treatment is stated to result in improved strength and/or elasticity and/or a modification of surface particularly of lustre. The teatment may be applied to finished materials containing natural or artificial fibres, e.g. viscose, nitrocellulose or cuprammonium artificial silks either under tension so as to allow the materials to shrink; alternatively, artificial filaments &c. may be treated continuously with their production. After treatment, the acids are preferably removed by treatment with water alone or water containing alkali or base. Additions having no action upon the acids', e.g. glycerin glucose or other sugars, sodium sulphate or other salts, alcohols or sulphonated oils may be made to the bath. Suitable acids are benzyl sulphonic acid, benzene sulphonic acid and naphthalene and naphthol sulphonic acids. Instead of or in addition to sulphonic acids, other organo-mineral acids derived from oxy-mineral acids other than sulphuric may be employed, e.g. methyl phosphinic acid or nitro phenyl phosphinic acids. The invention is particularly applied to the coagulation of viscose made from alkali cellulose unripened or ripened for a relatively short time. In an example, viscose obtained from alkali cellulose unmatured or matured for a short time, e.g. 20-30 hours, and which viscose has been allowed to age for 70-80 hours, at 17 C., is spun through nozzles 0.08 mm. diameter into a 60 per cent aqueous solution of benzene sulphonic acid maintained at 10 C., the length of immersion being 20 inches. The yarn is wound on -a bobbin rotating with a peripheral speed of 30 metres per minute, such bobbin being run in or sprayed with water. A viscose, as in the preceding example, is coagulated in an aqueous bath containing 10 per cent sulphuric acid, 1 per cent ammonium sulphate. 15 per cent sodium sulphate and 10 per cent glucose; and the formed filaments' are carried around a feed roller into a 60 per cent aqueous solution of benzene sulphuric acid. Specification 335,894 is disclaimed; also the employment of baths containing sulphonation products of mineral oils together with substantial quantities of sulphuric acid and of sulphates.
