Title: Manufacture of derivatives of carbinol
IPC: C12P33/00
Filed: 1930-10-15
Abstract: Optically active hydroxyarylacetylcarbinols and arylmethoxyarylacetylcarbinols are manufactured by fermenting with yeast a carbohydrate in the presence of an aromatic aldehyde containing in the nucleus a free hydroxyl group, an acylated hydroxyl group or an arylmethoxy group, with or without other substituents such as a methoxy group, and, if required, splitting of any acyl group or arylmethyl group present in the product. When starting from the acylated hydroxybenzaldehydes the acyl group is usually split off during the fermentation.  In the case of aldehydes containing arylmethoxy groups, the aryl methyl residue may be split off after the fermentation or after further treatment of the arylmethoxyarylacetylcarbinols.  In examples: (1) grape sugar is fermented with yeast in the presence of m-acetylhydroxybenzaldehyde, producing laevo-m-hydroxyphenylacetylcarbinol; (2) the same product is obtained using m-hydroxybenzaldehyde; (3) grape sugar is fermented with yeast in the presence of m-benzylhydroxybenzaldehyde (prepared from m-hydroxybenzaldehyde and benzyl chloride) yielding m-benzylhydroxyphenylacetylcarbinol; (4) laevo-3-hydroxy-4-methoxyphenylacetylcarbinol is similarly prepared from isovanillin.

Filed: 1969-06-23
Abstract: 1,211,517. Automatic width control. CORNING GLASS WORKS. June 23, 1969, No.31593/69. Heading G3R. The width of a ribbon of molten metal flowing from the outlet of a furnace or forehearth is compared with a desired width so that any error produces pulse code signals which are applied to operate a stepping motor to correct the error by adjusting the flow from the outlet. As shown, molten glass 78 flows from outlet 52 of a forehearth 51 and passes between rolls 71, 72 to form a ribbon of desired thickness for transport by a conveyer 150 to apparatus (not shown) which produces a succession of blown glass articles. The error in width of the ribbon on the conveyer is determined by an electronic unit 41 detecting infrared emission from the hot ribbon and comparing the actual width with a desired width. Unit 41 produces a direct voltage, corresponding in polarity and amplitude to the sense and magnitude of the error, which is applied to a unit 43 producing pulses of corresponding polarity and duration to operate periodically one or other of two relays 56 or 57 according to the sense of error. Direct voltage pulses of one polarity or the other are thus applied from a source XY to an amplifier 49 which produces corresponding pulses having such a four-step sequence that a step-by-step motor 11 is rotated in the appropriate sense to correct the width by raising or lowering a stopper 53 so as to adjust the rate of flow from forehearth outlet 52.
