Title: Improvements in or relating to the treatment of casein fibres
IPC: D06M13/12
Filed: 1938-04-05
Abstract: 500,013. Artificial threads ; casein; dyeing textile materials. NAAMLOOZE VENNOOTSCHAP ONDERZOEKINGSINSTITUUT RESEAHCH. April 5, 1938, Nos. 10450 and 10451. Convention dates, May 11, 1937 and May 26, 1937. [Classes 2(ii). 2 (iii), and 15 (ii)] Casein fibres are rendered resistant to shrinkage or sticking in hot acid dye baths by treating them with nitrous acid and with an aldehyde or a substance, such as hexamethylene tetramine, which gives rise to an aldehyde. Nitrous acid may be added in the form of a mixture of an alkali nitrite with an acid. If, however, the casein fibres are treated with an alkali nitrite without the addition of an acid, a slow reaction takes place between acid groups in the casein and the alkali nitrite, with the liberation of sufficient quantities of nitrous acid. When treatment with nitrous acid is effected in the latter way, the casein fibres are additionally rendered resistant to swelling during washing in alkaline baths following the dyeing process. Where the treatment with nitrous acid is too drastic, the fibres become yellowed, but this defect may be removed by treatment of the fibres with a reducing bleaching agent such as sodium hyposulphite. After treatment with nitrous acid and an aldehyde, any carboxyl groups remaining in the casein molecule may be neutralized, for example with alkaline earths, and the fibres may be treated with softening agents such as glycerol, sulphonated oils, sulphonated fatty -alcohols, &c. Where the nitrous acid is formed by the reaction between the casein and an alkali nitrite, the reaction may be carried out in the presence of a neutral dehydrating salt such as sodium sulphate or magnesium sulphate. In examples, casein fibres formed by spinning an alkaline casein solution into an acid coagulating bath, are treated (a) with formaldehyde and, after washing and drying, with a solution containing sodium nitrite and acetic acid ; (b) with nitrous acid and, after washing, with formaldehyde; (c) with formaldehyde and, after drying, with a solution containing sodium nitrite and sodium sulphate. In a further example, casein fibres treated according to (a) are bleached with sodium hyposulphite and then treated with lime.

Filed: 1923-04-20
Abstract: 217,380. Popatlal, P., and Laythorpe, F. A. April 20, 1923. Centrifugal actuation. -- A centrifugal governor operated from one of the road wheels of a motor-vehicle actuates a movable contact to short-circuit the magneto or battery, the sparking plugs of the respective cylinders being short-circuited in succession. The flexible shaft 27, Fig. 2, from the front wheel rotates the spindle 13 and the governor weights 41 and as the latter move outwardly the collar 38 rises, carrying with it the sliding plunger 16 until, when the predetermined maximum speed is reached, the cupcontact 17 reaches the longest of the contacts 9. The sparking plug corresponding to the longest contact thereby ceases to work and the other sparking plugs are successively short-circuited in a similar manner. Means to render the speed controller inoperative or to prevent the engine starting is shown in Figs. 5, 6 and 7. In the position 55 the hollow spindle 13 is clutched to the flexible shaft 27. In the position 56 the lever arm 52 completes the circuit through the contact 47 thus short-circuiting the magneto or battery, and making it impossible to start the engine. In the position 57 the circuit is restored - to the sparking plugs and the peg 51 maintains the clutch element 23 out of engagement with the element 24, thus putting the speed controller out of action.
