Title: Improvements relating to circular-knit, multi-feed stockings and method of making same
IPC: D04B9/46
Filed: 1949-04-26
Abstract: 704,062. Knitting. SCOTT & WILLIAMS, Inc. April 26, 1949 [April 26, 1948], No. 11117/49. Class 74 (2) A stocking has the foot knitted in multicourse spiral and the heel and toe in multicourse reciprocatory knitting, the heel and/or toe pocket having one or more single-sided sutures. The heel or toe pocket of Fig. 3 is knitted on a two-feed machine. Courses 9 and 10 are knitted from right to left. Courses 11 and 12 are then knitted from left to right, ending on wale 17 and, as the needles start moving to produce courses 13 and 14, knitted from right to left, the first two needles, that is those knitting wales 17 and 18, are picked up out of action, producing floats 20, 21, which are knitted into successive stitches by the needle knitting wale 19. This cycle is repeated to complete the narrowed segment. All needles are. then restored to action and the machine knits a gusset shown as of four courses, but which may be of, say, eighteen courses and have tapered ends. Approximately the same needles are now picked up as were inactive at the end of the narrowing courses and the widened segment is formed, one needle being picked up at the end of each reciprocation, and three put back, giving a net increase of two. Continuity of wales throughout the pocket and two single-sided sutures are thus produced and eyelet formation is minimized. The courses of the two segments may be staggered with respect to one another. The welt may also be knitted in multi-course circular knitting.

Abstract: The invention comprises the leuco-sulphuric ester of 3-(1-aminoanthraquinone-2 - carboxylamido) - benzanthronepyrazolanthrone and the salts thereof which are made by treating 3 - (1 - aminoanthraquinine - 2 - carboxylamido) - benzanthrone-pyrazolanthrone with a sulphating agent in the presence of a metal and a tertiary base or an organic oxide derived from a secondary amine, or treating a metal salt of the corresponding leuco derivative, or a complex thereof, with a sulphating agent in presence of a tertiary base or an organic amide derived from a secondary amine.  Amides specified are dimethylformamide, diethylformamide, dimethylacetamide, formylpiperidide, tetramethylurea, and diethyl - p - toluene sulphonamide.  Diluents may be acetone or nitrobenzene. Sulphating agents specified are chlorosulphonic esters, sulphur trioxide, and additional products of the latter with bases. Catalysts specified when an amide is used are potassium ethyl sulphate, sodium 2-naphthol - 6 - sulphonate, calcium naphthalene-2.6-disulphonate, sodium b -naphthalene sulphonate, ferric chloride and magnesium chloride.  In an example, the vat dye is reacted with zinc dust in dimethylformamide in presence of sodium b -naphthalene sulphonate, and the reaction mixture is cooled and reacted with dimethylformamide-sulphur trioxide. 3-Aminobenzanthronepyrazolanthrone is obtained by nitrating 3-bromobenzanthrone to give 3-bromo-9-nitrobenzanthrone, which is condensed with pyrazolanthrone, followed by reduction of the nitro group, and fusion with alcoholic potash.  3 - (1 - Aminoanthraquinone-2-carboxylamido)-benzanthronepyrazolanthrone is obtained by condensation of 3-aminobenzanthronepyrazolanthrone with 1-nitroanthraquinone-2-carboxylic acid chloride and treatment with ammonia.

Title: Improvements in or relating to resilient bushes and their manufacture
IPC: B29C70/68
Filed: 1948-04-28
Abstract: 649,831. Resilient bushes; assembling rubber bushes. MILES, Ltd., H. G., and BOOLE, R. April 28, 1948, No. 11590. [Class 108(iii)] In a resilient bush of the type comprising an outer metal sleeve having therein rubber or the like filling an annular space between the sleeve and an inner metal sleeve or member the rubber being bonded by vulcanization to the sleeve or the inner member or both, the end portions of the outer sleeve are inturned to hold the rubber under compression stress throughout, whereby tensile stress in the rubber due to contraction thereof by cooling after vulcanization is neutralized. In the arrangement according to Fig. 1, a rubber sleeve 3 is bonded under heat and pressure to initially cylindrical inner and outer metal sleeves 1 and 2. After cooling to normal temperature the bush is located on a core 4, Fig. 3, of a swaging tool and the ends of the sleeve 2 are swaged inwardly against axial pressure between internally coned surfaces 6 and 7 of lower and upper sections respectively of the tool. In a modification (Fig. 2, not shown) the ends of the rubber sleeve are recessed before bonding to prevent the rubber spueing beyond the metal sleeves during the swaging operation. In the arrangement according to Fig. 4 the swaging tool comprises cylindrical sections 11, which during the swaging operation engage the outer sleeve 2 of the bush to prevent " barrelling " thereof. In another arrangement (Fig. 5, not shown) the bush comprises two similar axially aligned sections each having a rubber sleeve bonded to inner and outer metal sleeves and in which the outer end of each outer sleeve is swaged before bonding takes place. The inner end of each rubber sleeve projects beyond the metal sleeves, the projections being distorted to compress the rubber in the two sections when the latter are force-fitted in abutting relationship into a boss or housing. Alternatively, the two sections may be compressed together by means of a nut on a spindle passing through the inner sleeve and having a fixed abutment at its other end. In a further arrangement, (Fig. 6, not shown), the rubber sleeve of each section is bonded to a common inner sleeve having a collar formed thereon intermediate its ends and the outer sleeve is formed in two sections which may or may not be bonded to the rubber. The bush is force fitted into a housing to compress the rubber sleeves into abutting relationship.
