1,35,868. Agitating and aerating liquids. PATENTAUSWERTUNG VOGELBUSCH G. m. b. H. March 31, 1965 [May 8, 1964], No. 13589/65. Heading B1C. A fermentation vat 6 has three or more vertical baffles 1-5 mounted with one vertical edge joined to the container wall at 8 and the other to an adjacent baffle at 7; below them rotates a gas injector 10 supplied with gas through its hollow shaft 18. The lower edges of the baffles are rounded, or, at least above the part of the gas outlets 12, curved in the direction of rotation as at 1 - 511; the inner parts of the baffles are deeper than the outer and the baffles are hollow for passage of a heat exchange medium, see Figs. 1, 3 and 4 (not shown). The arms 15 of the gas injector, which may be two or more in number, are in the form of open grooves on the rear side so that their crosssection is in the form of the front part of a streamline profile which is completed by the phase boundaries of the vacuoles 17 formed on rotation (see also Fig. 4, not shown). In operation fluid circulates upwards in the outer compartments 11 and downwards in the central compartment 13.
摘要:
The invention refers to a method of biotransforming a carbohydrate of a raw material into a chemical, by cultivating Lactobacillus diolivorans in the presence of the raw material to produce a chemical substance, and isolating the chemical substance in the purified form, and the use of L. diolivorans in one of a series of biotransformation methods, wherein carbohydrates from at least two different carbohydrate sources of low purity are transformed into chemicals.

摘要:
A rotary drum filter having a filter aid layer on its filter surface is provided with an adjustable scraper at the line of discharge of the filter cake and with an adjustable stripper adjacent the line of wet filter cake formation as the filter cake emerges from the slurry tank. The scraper is automatically advanced toward the drum to progressively remove the filter cake with portions of the filter aid layer as the drum rotates and the stripper also is either manually or automatically advanced toward the drum to maintain a substantially constant thickness of filter cake on the layer of filter aid as the thickness of that layer progressively decreases.
