Title: An improved method of constructing brushes
IPC: A46B3/16
Filed: 1924-04-07
Abstract: 219,906. Rutter, S. E. April 7, 1924. Bristles, fixing. - The handle 1 formed from a metal rod, is provided with a wire loop 4, the ends of which pass through apertures 7 in a ferrule 8 provided with a central aperture to receive the handle 1. The bristles 10 are bent double and engaged by the wire loop, the handle and the ends of the loop being drawn through the ferrule 8 to compress the bristles. The ends of the loop are cut off to a suitable length and bent laterally or otherwise secured outside the ferrule. The wire loop may be permanently secured to the handle by passing it through a tranverse aperture 3 and subsequently flattening the adjacent end of the handle. When bristles or hair of a soft nature are used they may be bound with wire or other material before being drawn into the ferrule.

Title: Manufacture of ortho-aminophenylpropionic acid, its substitution products or homologues
Filed: 1926-03-31
Abstract: 250,250. I. G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister, Lucius & Briining). April 6, 1925, [Convention date]. Samples furnished. Salts of o-aminophenylpropionic acid or its substitution products or homologues are obtained by treating hydrocarbostyril or its substitution products or homologues with an alkaline agent at a raised temperature. The products are intermediate compounds for the preparation of dyestuffs and synthetic drugs. In an example, hydrocarbostyril is heated with barium hydroxide and water under pressure to 150‹ C., the reaction mixture is diluted with water, treated with sodium carbonate to precipitate the barium, and filtered. The sodium salt of o-aminophenylpropionic acid is obtained from the filtrate by evaporation.

Patent GB-706476-A (GB)
Title: Improvements in or relating to the manufacture of sintered articles
Inventor: SAMUEL ROBERT LIONEL
IPC: B22F3/10
Filed: 1950-04-11
Abstract: In a method of making sintered articles a sinterable metal or metallic carbide powder is mixed with a flux comprising a silicone or an organic silicate and the mixture moulded, preferably without the use of substantial pressure and then sintered.  A compact mass can be obtained by using a suspension of fine metal powder in a flux dissolved in a liquid carrier and pouring the mix into a mould and allowing the carrier to evaporate.  Vibrating the mould at ultrasonic frequencies will facilitate the compacting.  Moulds of plaster of Paris may be used to absorb the carrier liquid.  As an example, a flux prepared by diluting 5 ccs. ethyl silicate with 20 ccs. methylated spirit slightly acidified with hydrochloric acid was mixed with fine iron powder of less than 240 mesh to form a liquid suspension which was poured into a mould on a vibrating table and allowed to dry in air for 2 hours.  The compact was sintered in a gas-fired oven for 2 hours at 1380 DEG C.  After compacting the articles may be immersed in a solution of sodium ethylate or lead acetate in alcohol or in a mixture of alkali metal and alkaline earth metal chloride and heated for 3 hours at 850 DEG C. before sintering for 3 hours at 1250 DEG C.  In other examples, ethyl silicate is used as the flux for nickel powder. the mix being of a consistency to be extruded as a rod before sintering at 1320 DEG C. and also for powders containing cobalt 80 per cent., chromium 20 per cent. or chromium 70 per cent. iron 30 per cent. and carbon less than 0.15 per cent. or chromium 70 per cent., nickel 30 per cent. or chromium 65 per cent. and cobalt 35 per cent.  Ethyl silicate is also used as the flux for a three-layer compact comprising an inner layer of iron 70 per cent., cobalt 30 per cent., and outer layers of chromium 60 per cent., cobalt 40 per cent., the sintering being at 1340 DEG C. for 2 hours: alternatively the former mixture may be used to fill a cavity in a compact of the latter mixture.  Other mixtures using ethyl silicate as a flux are alumina 30 per cent., chromium 70 per cent. or kaolin 10 per cent., chromium 65 per cent., carbon 0.1 per cent., balance iron or tungsten carbide 94 per cent., cobalt 6 per cent. Iron articles made according to the invention may in addition be subjected to a chromium diffusion process as described in Specifications 646,637 and 646,638, [both in Group II].

Title: Improvements in the production of crepe yarns and fabrics
Filed: 1932-03-30
Abstract: Highly twisted crape threads comprise both saponified and unsaponified cellulose ester filaments.  The proportion of saponified filaments is preferably \ba1/4\be-\ba3/4\be, and in the case of cellulose acetate filaments, the degree of saponification corresponds to a 10-30 per cent loss in weight.  Doubling of the saponified with the unsaponified filaments may take place continuously with the production of either or both components. Two separate threads may be obtained from the same spinning jet, e.g. as described in Specification 344,351, and one thread saponified, and the two doubled.  Saponification may be effected as described in Specifications 304,596, 313,404, 313,971, 314,446, 314,447, 316,521, 318,468, and 330,950, [all in Class 2 (ii), Cellulose &c.].  The thread is twisted to 50-75 turns per inch, and if desired, in two or more stages with an intermediate treatment adapted to set the filaments, as described in Specifications 386,344 and 386,374, [both in Group IX].  Other materials such as silk or wool may be incorporated.  The resulting threads may be further modified, e.g. as by any of the treatments described in Specifications 332,903, [Class 120 (iii), Yarns &c.], 348,589, 351,999, 352,000, 352,451, 356,233, 357,084; 357,577, 358,585, [both in Group IX]; 365,040, 365,041; 375,355, [Group IX]; 379,285, and 388,796.

[Class 79 (iii).] In association with means for facilitating the placing of lifting- jacks in position beneath motor vehicles of the kind comprising a guide rail or strip permanently attached to the vehicle, a sheath or cover 5 is provided which normally serves to protect the guide member 3 from mud and dirt and which, when it is desired to use the jack, is removed and inserted into a socket or tubular head carried by the jack so that it may serve as a handle for sliding the jack along the strip into position. The sheath fits the strip loosely, being retained in position and prevented from rattling by the curvature of the strip. The socket head 6 on the jack, which may be of rectangular form, is a tight sliding fit on the sheath. Various ways of attaching the strip, either by securing it to the vehicle axle or suspension spring or clamping it therebetween as in Fig. 1, are described and shown, the arrangements generally being such as to allow the jack head to bear directly against the part to be lifted. In Fig. 9, the guide strip is shown attached to a chassis side member 7 and directed outwards under the running board 9.

Abstract: 710,503. Creels. BRITISH CELANESE, Ltd. April 23, 1952 [April 25. 1951], No. 9646/51. Classes 120(2) and 142(1) Bobbins are mounted on detachable pegs in a creel, the pegs being mounted in pairs with the pegs of each pair converging towards each other less than is usual, so that the bobbins may be closely packed. Each bobbin is mounted on a peg 11 provided with a handle 13 and a member 24 channelled to fit vertical pillars 26 of the creel frame and having slots for engaging pins 27 on the pillars. The pegs are arranged in pairs with the centre lines of each pair converging towards, but intersecting beyond, a common yarnguide eye 38 forming the input guide of a tension device of the type described in Specification 662,442. A yarn in passing from a bobbin to the associated guide eye is led under a guide wire 43 and over a guide edge 44 which deflect the yarn through a point more nearly in alignment with the peg than the guide eye. The yarn from the other bobbin of the pair is tied to the end of the yarn of the first bobbin. When a bobbin is exhausted, the peg together with the empty bobbin is removed from the frame. A long series of. pillars 26 are joined together to form a package chase 49 and an equal number of rods 37 from a tension chase 51, each of the pillars 26 receiving pegs, one above the other, on opposite sides thereof alternatively. Thus the pegs on each pillar 26 serve the tension devices of two different rods 37 so that the vertical spacing of the tension devices is twice that of the pegs. A servicing trolley may be provided having a framework including members similar to the pillars 26.
