Title: Process for imparting to cellulosic textile fabrics an increased resistance to shrinkage
IPC: D06M15/423
Filed: 1945-01-26
Abstract: A process for imparting to cellulosic textile fabrics an increased resistance to shrinkage when washed comprises treating such fabrics with an aqueous solution of an etherified melamine-formaldehyde condensation product, containing at least one formaldehyde-reactive hydrogen, and formaldehyde which is present in an amount of at least one third of the weight of the etherified melamine-formaldehyde condensation product and thereafter heating the fabric in order to produce a water-insoluble resin thereon.  The melamine-formaldehyde condensation product may be a methylolmelamine in which resinification has not proceeded to any considerable extent, i.e. one made from one molecular proportion of melamine and substantially three molecular parts of formaldehyde.  In an example the methyl ether of a methylol-melamine is prepared by mixing 200 parts melamine, 400 parts of a 40 per cent aqueous formaldehyde solution and 5 parts by weight of disodium hydrogen phosphate for 15 minutes at 75 DEG  C.  The cooled mixture is stirred into 972 parts by weight of methanol.  Aqueous hydrogen chloride is then added and the whole allowed to stand for 30 mins. before the solution is neutralized with an excess of sodium bicarbonate. The solution is concentrated by evaporation of water under reduced pressure at 40 DEG  C.  The impregnating solution may contain 5-50 per cent by weight of the etherified melamineformaldehyde condensation product.  Amounts greater than 15 per cent by weight lead to crease-resistant finishes. After impregnation, the fabric may be dried and then heated or dried and heated, in a single operation, the heating preferably being carried out above 100 DEG  C. The impregnating solution may contain an acid catalyst such as ammonium dihydrogen phosphate, ammonium chloride or tartaric acid. In an example, cotton fabric is steeped in a neutral aqueous solution of an etherified melamine-formaldehyde condensation product to which is added ammonium dihydrogen phosphate and aqueous formaldehyde.  The fabric is removed and squeezed to retain its own weight of liquor, stentored at the required dimensions, dried and finally heated at 150 DEG  C.

Title: Improvements in magazine talking machines
IPC: G11B17/00
Filed: 1943-12-15
Abstract: 570,061. Magazine gramophones. KOSH, T. H., and WRIGHT, S. J. Dec. 15, 1943, No. 21050. [Class 40 (ii)] Relates to magazine gramophones of the kind in which the records are in trays in the magazine, the record to be played is brought out of the magazine to a position above the turntable while the turntable is in a lowered position, and the turntable is then raised to the playing position and in doing so takes and lifts the record from its tray. According to the invention, the turntable is raised and lowered by means of an endless chain 1 forming a loop with two vertical sides 6, 7, a trigger device being provided to connect the turntable support to one of the sides 6, 7 alternately. The turntable (not shown) is fast on a vertical shaft 8 vertically slidable in the frame 10 of the machine and held up by a bracket 28 on a block 12 guided by a sleeve 11 on a vertical post 9. The block 12 is formed with slots 13, 14 for the sides 6, 7 of the chain, and is provided with a trigger 16, 17 formed with side teeth 18, 19 and normally in central neutral position, Fig. 1. To cause the turntable to be raised from its bottom position, Fig. 1, a control rod 29 is lifted whereby a collar 31 thereon turns the trigger 17, 16 to make the tooth 18 engage the up-moving side 6 of the chain. When the turntable reaches its upper position, the trigger 17, 16 is turned back to neutral position by striking another collar 30 on the control rod 29 ; at the same time a pawl 24, Fig. 4, pivoted on the block 12 engages ratchet teeth 25 on the post 9 and holds the turntable up in playing position. To bring the turntable down again, the control rod 29 is depressed whereby the collar 30 thereon turns the trigger 17, 16 in the opposite direction to cause the other tooth 19 to engage the downmoving side 7 of the chain ; at the same time, the arm 17 of the trigger strikes an arm 27 on the pawl 24 and turns this pawl away from the ratchet teeth 25. When the turntable reaches its bottom position over a shoulder 32 on the' post 9, the trigger 17, 16 strikes the collar 31 and is thereby moved back to neutral position. The trigger is held in its positions in the fashion of a tumbler switch by a coiled compression spring 23 surrounding a pin 22 pivoted on the block 12 and projecting through a slot in the end of the arm 16 of the trigger. The turntable is driven by a gear wheel 33 which becomes clutched to the shaft 8 when the turntable is raised to the playing position; the clutch comprises a pawl 46 on the gear wheel adapted to engage a notch in the shaft 8. The chain is stretched over pinions 2, 3, 4, 5, and is driven by the pinion 5 either continuously or when the turntable is to be moved up or down. The control rod may be operated automatically in accordance with the playing of the records. In modifications, instead of the arm 17, a separate lever or a vertically sliding member may be used to operate the trigger by the cooperation of a pin with an inclined slot.

Title: Improvements in and relating to a process for the purification of xylenes by distillation
IPC: C07C7/06
Filed: 1948-08-13
Abstract: Non-aromatic hydrocarbons are separated from admixture with xylenes, ethyl benzene and styrene by distilling the mixture in the presence of pyridine, whereby the non-aromatic hydrocarbons are preferentially volatilized in the form of their azeotropes with pyridine.  The distillate is homogeneous; but by adding water to it, preferably with cooling, separation into two layers occurs. The upper layer is rich in non-aromatic hydrocarbons, the lower is rich in pyridine.  The upper layer may be distilled in a fractionating apparatus, and the pyridine therein recovered as a distillate in the form of azeotropes with a portion of the nonaromatic hydrocarbons; this distillate is returned to the decanter.  The aqueous pyridine layer from the decanter is fractionated under six atmospheres gauge pressure to give anhydrous pyridine as bottoms, and an aqueous distillate which is returned to the decanter.  In an example, a cracked petrol fraction boiling within the range 130-145 DEG  C. and containing 54 per cent xylenes was mixed with pyridine (about 2 volumes); and the mixture was fractionated using a column packed with Raschig rings (equivalent to 15 theoretical plates) and operated with a reflux ratio of 9 : 1. The distillation was stopped when the temperature at the head of the column reached 126 DEG  C.  The residue in the boiler contained 1.5 per cent pyridine, the remainder being xylenes containing only 3 per cent non-aromatic hydrocarbons.
