Title: Process for the preparation of acetyl methyl carbinol and diacetyl
IPC: C12P7/26
Filed: 1929-06-26
Abstract: 337,025. Verhave, T. H. June 26, 1929. Addition to 315,264. Acetyl methyl carbinol; diacetyl.-A mash consisting of a fermentable carbohydrate, a nitrogen compound, a. phosphate and a carbonate is fermented by means of bacteria which under normal conditions produce 2, 3-butylene glycol, and the fermenting mash is subjected to an aeration insufficiently strong to prevent the formation of butylene glycol, the aeration being continued after the main fermentation period until the butylene glycol has been substantially converted into acetyl methyl carbinol. The volatile fermentation products present in the escaping mixture of air and fermentation gases are recovered in washing devices, the absorbing liquids of which may be worked up together with the fermented mash. The acetyl methyl carbinol produced may be converted to diacetyl by the action of oxidizing agents. In an example, potatoes are liquefied by steam under pressure and then mashed in the usual way with malt. The temperature of the saccharified mash is adjusted to 37‹ C. and superphosphates and limestone are added together with a mother culture of aerobacter aerogenes in a malt-rye mash. The mash is subjected to aeration which is increased during the course of the fermentation until all butylene glycol is converted into acetyl methyl carbinol. The escaping gases are washed with cold water, and together with the fermented liquid are oxidized by means of anhydrous ferric chloride. After rectification, a diacetyl with a water content of 13 per cent is obtained.

Title: Single bipolar transistor memory cell and methods of operation and fabrication
IPC: H01L21/74
Filed: 1974-05-06
Abstract: 1446386 Semi-conductor devices SIGNETICS CORP 6 May 1974 [21 May 1973] 19850/74 Heading H1K A single bipolar transistor memory cell comprises an epitaxial layer 26 having emitter and base regions 42, 37 on a substrate 11 of opposite conductivity type having buried regions 16, 21 of opposite conductivity types, and an insulating layer 39 through which metallizations 49, 51 extend to contact the base and emitter regions only. In operation, a voltage is applied to the emitter with the base at a fixed voltage to cause depletion of the base region and charging of the collector-substrate capacitance, which is enhanced by the buried P and N regions 16, 21, to form a first stable state. The stored charge leaks at a rate determined only by the reverse bias on the PN junction between layers 11, 26. When the voltage on the emitter is reduced below that on the base the collectorsubstrate capacitance is discharged to form a second stable state. The state of the cell may be read by placing a voltage on the charge line. If current flows then the collector-substrate capacitance is uncharged. The transistor regions are produced by masking with SiO 2  and diffusion or ion implantation of P, B and As. The emitter and base contacts are formed by photolithographic techniques to remove metal from a deposited layer which extends through apertures in the final insulating layer 39.
