Title: Improvements in the manufacture of styrene and the like
IPC: C07C5/333
Filed: 1930-08-19
Abstract: Styrenes are obtained by the catalytic dehydrogenation of aromatic compounds having at least one side chain CH2.CH2R (in which R represents hydrogen or a hydrocarbon residue) at temperatures between 450 and 700 DEG  C., but preferably above 600 DEG  C.  Examples of compounds of the above type are ethylbenzene, diethylbenzene, ethyldiphenyl, chlorethylbenzenes, isopropylbenzene, cymene, unsymmetrical ditolylethane, ethylnaphthalenes, &c.  Suitable catalysts are cerium oxide and/or zinc oxide promoted with metallic oxides such as those of tungsten, uranium and molybdenum.  These last-named oxides may also be used alone.  Silica gel may also be used.  The vapours are decomposed in a reaction tube made of glass, or glass lined, the use of metallic tubes such as iron or copper being avoided.  The styrene may be polymerized and separated from unchanged starting material by distillation.

Abstract: 517,154. Delivering blanks from hoppers. WILCOX, R. L., and WATERBURY FARREL FOUNDRY & MACHINE CO. Aug. 23, 1938, No. 24810. [Class 78 (i)] [Also in Groups XXII and II] Blanks thrown into a hopper 131, Fig. 3, are stirred up by an agitator 163 rotating and also pivoting up and down about axes 157 and are lifted out by chain fingers 139 and delivered one by one to the upper end of a chute. The speed of the agitator and of the lifting chain fingers can be varied by a variable-diameter motor-driven pulley (144, Fig. 11, not shown) with V-groove sides which 'move apart so as to allow the V driving belt to move in to make the effective driving diameter less, the slack of the belt being taken up by moving the motor and pulley bodily .away from its driven pulley. The blanks contact at the lip of the hopper 131 with coiled spring fingers 175 which allow to pass only such blanks as lie in the right direction, thus acting as clearing fingers producing the effect of a stiff flexible brush. If too many blanks delivered to the chute plates 51 contact with a finger 211 a ratchet mechanism, Fig. 10, breaks the drive between shafts 184 and 147 thus stopping movement of the lifting fingers 139 and further delivery of blanks. Blanks 50, Fig. 2, pass into the chute plates 51 hanging by their heads or screwed-on nuts, and are pushed along by a reciprocated finger until they enter another auxiliary chute 39, Fig. 2. At the end of this chute a slide with sharp end 82<1> Fig. 6, separates a blank from the succession of blanks and pushes it into a notch 79 which carries it broadside to a spring-pressed head gripper 112, Fig. 15, which moves it to position between the threading platens 24, 25 which remove it from its spring grip.
