IPC: D06P5/12
Filed: 1932-04-09
Abstract: Aniline-black dyeing; printing; cellulose esters or ethers, dyeing.--The production of oxidation colours on materials made of or containing cellulose esters or ethers is resisted locally by the application of a composition containing an oxidizable compound of an inorganic acid, said compound having mild reducing properties, and containing a dyestuff resistant to the oxidizable compound and having affinity for, or capable of being fixed upon, the materials.  Thus a composition containing an oxidizable amine and a chlorate may be applied before or after the local application of the resist composition.  Specified oxidizable compounds are sulphites, thiosulphates, and stannous and ferrous salts of inorganic acids, and specified oxidation colours are those obtainable by oxidation on the material of aniline, applied, for example, as described in Specifications 332,624, [Class 15 (ii), Dyeing, Processes &c. for], and 390,819, p-aminodiphenylamine and p-phenylenediamine.

Various embodiments of the invention are described. In Fig. 1, the mass a constrained by springs b<1>, b<3>, b<2>, b<4> is gradually excited to movement in a circle by a crank g acting through an extremely flexible coupling k. In Fig. 2, the mass is constrained by rectangularly arranged springs b<1>, b<2> and the flexible coupling comprises a crank g formed at the end of a wire coil k. Such coupling means may extend on both sides of the mass a. In Fig. 4, an annular mass a, supported peripherally by a number of radial springs b<1>, b<2>, is driven through a spring k by a concentric crank g, an initial displacement being produced either artificially or by the sag of the springs. In a numbers of forms the mass is supported in the manner of a circular pendulum at the end of a spring b, Fig. 5, or of a rod connected to the spring, Fig. 8, the upper end of the spring being fixed to a support, and the coupling k being in the form of a conical spring fixed to the mass with its end engaging a hole or slot in a crank disc g. One or more arms c may be carried by the pendulum rod as shown in Fig. 8, enabling linear motion to be transmitted to or from the device through an elastic coupling k<1>. In another form, the crank disc g is at the upper end of the pendulum, being connected through a spring, such as k, to a ring secured to the pendulum rod and enclosing the fixed support. In Fig. 9, a pair of weights a<1>, a<2> is supported by a membrane or elastic plate b and executes a tumbling movement. In another form, a pendular mass is supported by a number of spring bars or coiled springs. Slight modifications of the spring coupling means k, shown in Figs. 1 and 2, are described. An elliptical movement may be obtained by an asymmetric arrangement of the springs &c. Specifications 7252/86 and 1644/78, [Class 103, Railway &c. vehicles], are referred to.
