Title: Improvements relating to a process of purifying an opacifying agent for enamels, glazes, and glasses
IPC: C03C1/04
Filed: 1932-03-14
Abstract: Sodium antimonate and calcium stannate used as opacifying agents for glasses, glazes and enamels are purified by treatment with a solution of a cyanide such as of sodium or potassium.  The purification is resultant on the formation of soluble cyanides or complex cyanides of specified contaminating metals or on the dissolution of the oxides in the cyanide solution.  The opacifying agent and the solution are stirred, say for three hours, at ordinary or elevated temperature, and should be separated before decomposition of the complex cyanides occurs.  A period of 12-24 hours is specified.  The leaching solution should be alkaline, and sodium hydroxide may be added for this purpose.  The sodium antimonate may be obtained from metallic antimony and sodium hydroxide, or as a bye-product in lead softening.

Title: Cationic dyestuffs
IPC: C08K5/00
Filed: 1976-02-26
Abstract: There is described a process for dyeing, printing and spin-dyeing materials that contain acidic groups, these materials consisting wholly or predominantly of polymerised unsaturated nitriles, acid-modified polyesters or acid-modified polyamides. The dyes used are cationic and have the formula <IMAGE>  where the substituents are as described in Claim 1. The process is particularly suitable for dyeing wet-spun acrylics, since the dyes are not sensitive to foreign ions such as thiocyanate (rhodanide) ions still adhering to the fibre from the production thereof.

[Also in Group XXVII] In a pedal bicycle having an engine-driven rear wheel 10 the engine crankshaft 1 is chain connected to a shaft 3 rotatably coupled to a shaft 4, and the shaft 4 is also rotatably coupled to a gear rotatably mounted on the pedal spindle 6 and connectable thereto through a clutch rendered operative by rotation of the spindle 6, whereby rotation of the pedals can start the engine, the shaft 4 being connected to the rear wheel by a chain 11. As shown, the shaft 3 is connected by alternatively clutchable gear pairs to the shaft 4. The gear is connected by a chain 5 to the shaft 4, and the clutch comprises a thread on the spindle 6 mounting a sleeve 7 so that forward rotation of the spindle by the pedals causes the sleeve 7 to move from the idling position shown to engage with the gear, thus transmitting pedal drive to the shaft 4 for either starting the engine or assisting the engine drive of the cycle. Rotation of the pedals in the opposite direction causes the sleeve 7 to be clutched to a bush 8 carrying an arm 9 operatively connected to an arm 13 of a rear wheel brake enclosed in a housing 12 to apply the brake. In a modification. Fig. 2 (not shown), the chain drive 5 is replaced by a pinion on the shaft 4 engaging with an internally toothed gear rotatably mounted on the pedal shaft.
