Title: Method for culturing hydrogen oxidising bacteria
IPC: C12M1/36
Filed: 1974-09-04
Abstract: 1435248 Culturing hydrogen-oxidizing bacteria AJINOMOTO CO Inc 4 Sept 1974 [5 Sept 1973] 38648/74 Heading C6F [Also in Division B1] In a method of culturing hydrogen oxidizing bacteria, the requisite intake of hydrogen, oxygen and carbon dioxide is provided without danger of an explosion, by circulating aqueous culture medium held in the fermentation vessel 1, Fig. 1, through each of two mixing units viz. unit 2 wherein gaseous hydrogen from reservoir 5 is dissolved in the circulated medium and unit 3 wherein oxygen from reservoir 4 is similarly dissolved. The levels of hydrogen in the oxygen-dissolving unit 3 and of oxygen in the hydrogen-dissolving unit 2 are monitored by gas chromatography apparatus 11 and 12, respectively, with a view to maintaining the concentration of the minor constituent in each case below that corresponding to an explosive composition. Thus the concentration of gaseous hydrogen in the oxygen-dissolving unit may be controlled by changing the circulation rate of aqueous culture medium through the hydrogendissolving unit or by changing the rate of introduction of gaseous hydrogen into the hydrogendissolving unit. The concentration of oxygen is controlled in a similar fashion mutatis mutandis. Carbon dioxide is introduced into the aqueous culture medium at any point of the circulating line of the medium e.g. at the fermentation vessel or with the gaseous hydrogen or oxygen. Parts 13 and 14 are infrared carbon dioxide analyzers and parts 15 and 16 are pressure gauges. Valves 17-20 control the introduction of carbon dioxide and oxygen or hydrogen, respectively, into the reservoirs 4, 5. In an alternative apparatus, Fig. 2, the mixing units 2, 3 consist of bubbling towers and the limiting oxygen content in unit 2 is monitored by measurements of the dissolved oxygen content. In Examples directed to the continuous cultivation of Hydrogenomonas eutropha ATCC 17697, the gas in the mixing unit 2 contained 91% by volume H2, 4% O 2  and 5% CO 2 , and the gas in mixing unit 3 contained 93% O 2 , 2% CO 2 .

Title: Sonar apparatus
IPC: B06B1/06
Filed: 1971-08-18
Abstract: 1306769 Electroacoustic transducers WESTINGHOUSE ELECTRIC CORP 18 Aug 1971 [15 Oct 1970] 38722/71 Heading H4J An electroacoustic transducer for transmitting and/or receiving acoustic energy has its beam pattern modified by acoustic absorbing material, positioned to absorb a portion of forwardly projected acoustic energy, to reduce the off axis response over a predetermined forward zone. The acoustic absorbing material has an acoustic impedance substantially equal to that of the medium in which the transducer operates, e.g. sea water. A side-looking sonar system located in the conning tower (14), Fig. 2 (not shown), of an undersea vessel (10) projects acoustic energy toward the sea bottom. The sonar system comprises a single transmit/receive transducer or separate transmit and receive transducers. Acoustic energy to or from the transducer or transducers which would otherwise hit the deck of the vessel and give rise to erroneous readings is absorbed by the acoustic absorbing material. The transducer 40 (Fig. 4) preferably has a length greater than 100# where # is the wavelength of the operating frequency in the ambient medium. It comprises a plurality of barium titanate elements 44 arranged end to end along a straight or curved surface. The active surface 42 of the transducer radiates useful acoustic energy. Acoustic damping material, e.g. of butyl rubber which may have dispersed therein aluminium particles, absorbs energy radiated from the rear surface of the transducer and a portion 52 extends beyond the active surface 42 to modify the lower portion of the beam. Acoustic absorbing material may, if desired, extend past the active surface to modify the upper portion of the beam. Potting material 60 having the same acoustic impedance as the ambient medium covers the acoustic absorbing material 52 and portions of elements 44 to protect the apparatus from the effects of the ambient medium. The device is mounted on a carrier by projections 35 and fastening means (not shown) which pass through apertures 37.
