Title: Fermentation of Hydrocarbons
IPC: C12P7/40
Filed: 1967-07-04
Abstract: 1,197,236. Microbiological oxidation. SUN OIL CO. 4 July, 1967 [31 Aug., 1966], No. 30745/67. Heading C2C. [Also in Division C6] In the microbiological oxidation of a liquid hydrocarbon substrate for production of oxygenated hydrocarbon derivatives, hydrocarbonoxidizing micro-organism is maintained dispersed in an aqueous nutrient medium under aerobic fermentation conditions, a liquid hydrocarbon substrate is continually fed to the dispersion under vigorous agitation of the mixture, and the rate of addition of the hydrocarbon is controlled so that the amount thereof in the dispersion in excess of the amount absorbed by the micro-organism cells does not exceed the limit of solubility of the hydrocarbon in the aqueous nutrient medium. The concentration of hydrocarbon dissolved in the aqueous nutrient medium may range from 5 to 200 p.p.m. Hydrocarbons: C 6 -C 10  benzenoid hydrocarbons, i.e. benzene and alkylbenzenes having up to four alkyl carbon atoms; 1-methyl-naphthalene, 1-ethylnaphthalene, 2-ethylnaphthalene or a normally liquid dimethylnaphthalene, from which naphthoic and salicyclic acids may be produced; and C 5 -C 10  alkanes, particularly n-paraffins and cycloparaffins such as cyclohexane and n-butyl cyclohexane. Micro-organisms: hydrocarbon-consuming species of the genera Micrococcus, Corynebacterium, Nocardia, Pseudomonas, Mycobacterium, Streptomyces, Aspergillus and Acetobacter. Examples are directed to the microbiological oxidation of p-xylene to α,α<SP>1</SP>-dimethylmuconic acid employing Nocardia corallina ATCC No. 19,070 on lard oil (Example 1) and to both p-toluic acid and dihydroxy-ptoluic acid employing Nocardia salmonicolor ATCC No. 19,149 on n-hexadecane (Examples 2, 3 and 4). In the procedure of Example 1 the p-xylene was continually metered into the fermentation broth and the concentration of the unconsumed p-xylene in the aqueous nutrient medium was maintained mainly in the range of 5-30 p.p.m. In the other Examples p-xylene was introduced into the broth along with n-hexadecane after an initial cultivation upon n-hexadecane only. Increasing concentrations of pxylene within the range 25 to 125 p.p.m. resulted in proportionately higher yields of the dihydroxy-p-toluic acid relative to the p-toluic acid. The acids are recovered from the aqueous phase and cells by a hydrocarbon solvent or ether. (It was observed that the p-xylene became distributed in about equal amounts between the aqueous phase and the cells). The aqueous nutrient medium utilized is specified.

Title: Acetoacetylated starch derivatives
IPC: C08B31/00
Filed: 1966-07-11
Abstract: Novel starch aceto-acetate esters of formula St-O-CO-CH2-CO-CH3, wherein Strepresents the starch molecule, may be made by reacting a starch or modified starch containing material which contains free OH groups with diketene in the presence of a catalyst.  Suitable starch starting materials are plant starches and high amylose starches, which may have been gelatinized, oxidized, dextrinized, etherified or esterified.  The reaction may be conducted in aqueous or non-aqueous media with acid or alkaline catalysts.  In aqueous media, suitably a pH of 4-11 is maintained, using an alkaline catalyst (e.g. NaOH) at 5-95 DEG  C.  In non-aqueous media acid (e.g. H2SO4, H3PO4) or alkali (e.g. pyridine) catalysts may be used, at 50-100 DEG  C. for acid catalysts or 80-100 DEG  C. for alkali catalysts.  The reaction medium may be present in amounts from 1-20 pts. by wt. per pt. of starch starting material. The diketene may be mixed with another acylating agent to produce a mixed ester product. The products suitably contain 0.01-61.5% acetoacetyl groups.
Patent GB-1138108-A (GB)
Title: Improvements in and relating to means for lateral guiding of a web of material
IPC: B65H23/032
Filed: 1967-07-06
Abstract: 1,138,108. Feeding webs. AKERLUND & RAUSING A.B. 6 July, 1967 [27 July, 1966], No. 31134/67. Heading B6B. Transverse web-registering apparatus includes a sensing member 9 which utilizes the flow of compressed air through an aperture 10 controlled by the web edge, a pressure box 13 operated by compressed air for displacing a web-roll or roller laterally and a control valve 5 and servo-valve 7 connected into a compressed air conduit system. With the web correctly aligned, its margin 70 covers the aperture 10 partly but not completely. Compressed air entering the control valve 5 from a pressure regulator 3 acts on the top surface of a diaphragm 20 and keeps it at a small distance from the contact surface on the valve housing 18 against the action of a spring. Through outlet opening 23, pipe conduit 6, chamber 53 in the servo valve 7, pipe conduit 11 and non-return valve 12, the compressed air acts on the diaphragm 15 of the pressure box 13 and is balanced by the spring 14. A small part of the compressed air escapes permanently from the servo-valve 7 through a retricted opening 59, but is replaced by new air from the control valve 5. A further part of the supplied compressed air flows through ducts 27 and 29 in the control valve 5, through a choking point 30 and duct 31 to a chamber below a diaphragm 21, from whence it flows via an opening 32 and a pipe conduit 8 to the sensing member 9. Deviation of the web causes a change in the volume of air escaping through the aperture 10. If the volume increases, the pressure acting on the diaphragm 21 decreases, so that the diaphragm moves downward and permits a needle valve 37, 39 to open more. This gives rise to a pressure drop in chamber 34, whereupon diaphragm 20 moves downward and allows a greater volume of air to pass through opening 23 to the servo-valve 7 and thence the pressure box 13. A reduction in the volume of air escaping from the aperture 10 causes a reduction in the through flow of air to the pressure box. This results in the diaphragm 15 pressing air back to the servo valve 7 via conduit 16, thereby increasing air pressure on the top side of a diaphragm 52. The diaphragm 52 therefore leaves the seat 56, allowing air to escape to atmosphere via groove 63, duct 64 and a control valve 65. The control valve 5 is designed such that in extreme cases when the diaphragm 20 shuts off the outlet opening 23 and the duct 27, the duct 27 will be opened before the outlet opening 23 is uncovered. This is achieved by having the centre of gravity of a circular washer 44 (bolted to the diaphragm) at a point opposite that part of the inside of the outer part 18 from which the duct 27 starts.

Abstract: 311,733. Airosana Trockeninhalations-Ges., (formerly Aerosan Ges.). May 15, 1928, [Convention date]. Vaporizing by heat; vapours, delivering.-In apparatus for vaporizing chemicals, particularly medicaments for inhalation, and distributing the vapours in the air of a room, the substance to be vaporized and the source of heat are disposed in a plain open chimney of uniform diameter so that a rapidly moving current of hot air is produced. In the form shown the substance to be vaporized is placed in a dish 5 mounted in a chimney 6 so as to leave an annular channel 9 for the passage of hot air rising from an electric lamp 4 in the lower part of the chimney. The lower part of the chimney is formed with openings for the inlet of air and the upper part 8 is hinged or otherwise made movable. The temperature to which the substance to be vaporized is heated may be varied by screening the air admission openings, by adjusting the height of the chimney or the height of the dish 5 above the lamp, or otherwise.

Title: An improved method of and apparatus for the electric selective remote control of definite operations employing synchronously running contact selectors
IPC: H04Q9/04
Filed: 1938-10-29
Abstract: 520,362. Electric signalling systems. LANDIS & GYR AKT.-GES. Oct. 29, 1938, No. 31382. Convention date, Dec. 24, 1937. [Class 40 (i)] In a system employing synchronously driven switches at the transmitter and receivers, each receiving switch is associated with a relay group which responds to all signals including disturbing impulses and prevents the final response of the receiver unless the relay group has been set exclusively by the signals appropriate to the receiver. In the receiver shown, the effective control operation is performed by a two position relay M operated by energization of one or other of its windings N, O. Closing of the circuit at m is effected in response to start, selecting and operating signals over contacts 1, 2, 4 of the switch F, and opening of the circuit in response to similar signals over contacts 1, 3 and 4. The start signal (A.C. as shown) operates E whereupon synchronous motor G drives the switch and holds itself over g for a revolution. A selecting signal arriving when switch F is on contact 2 energizes H which - holds itself, opens the circuit of winding O and closes a point in the circuit of winding N so that if no further signal arrives other than the operate signal on contact 4, winding N is energized and closes contact m. Any extraneous signal element either operates selector relay K over contact 3 to disconnect winding N or operates a protective relay L over contacts 5, 6, 7 which are not connected to selector relays, whereupon the circuit of both windings N and O are opened. Lack of synchronism also prevents a final operation. In a modification, Fig. 2 (not shown), four selecting relays are used to control two two-position relays, immunity against incorrect signals being obtained by a protective relay similar to L, Fig. 1, and by a counting relay set controlled over a second contact bank of the switch so that an excessive number of signal elements releases all the operated selecting relays. In a further modification, Fig. 3 (not shown), the counting set and additional contact bank are replaced by a checking relay controlled either in open circuit or in closed circuit by contacts of the selecting relays and disabling the two-position relay circuit if more than the correct number of selecting relays has been operated. The signalling may be effected by superimposition of A.C. or D.C. impulses over a supply network, or by variation of current of a supply network, the selector relays being sluggish to prevent response to momentary interruption of the network.
