[Also in Divisions C2 and C6] Microbial cells are cultivated in a system which consists of a plurality of compartments connected in series. Fermentable liquid and gas delivered to a column fermenter through a tangential inlet 24, Fig. 4, progress upwardly (together with microbial cells) through compartments 2, 3, 4 to the outlet 12. Between compartments, gas passes along under baffle 10 and then through the perforated plate partition member 1 separating the compartments whereas the cells and liquid travel up through duct 21. Baffles 11 and 22 reduce the turbulence at the liquid level in the compartments. According to a further embodiment, air distributing plates 39, Fig. 5, and baffle plates 10 and 11 are mounted for rotation on a shaft 35, the fixed partition members 1 have a single aperture 34 and stationary baffles 40 are fitted along each compartment. Radial slots (41, Fig. 6, not shown) divide the plates 39 into sectors, one or more of which may be angled or pitched. There may be separate gas and liquid inlets (5, 6, Fig. 1 not shown) and the perforated plate 16 may then be replaced by a sintered disc or an annular sparger. The total cross-sectional area of the aperture or apertures in each partition member is typically less than 1.4% of the cross-sectional area of the partition member calculated with respect to an imperforated member. The apertures may be in the form of tubes having a ratio of length to diameter greater than 2:1. Mushroom-shaped or weighted valves may be fitted in the apertures to minimise downward flow. The flow rate of oxygen-containing gas (aerobic fermentation) may amount to 0.1-3 vols per minute based on the total volume of the combined fermentation compartments.

Abstract: 1,141,090. Intruder alarms. FRANCE, ARMED FORCES, MINISTER OF. 6 Dec., 1967 [14 Feb., 1967], No. 55569/67. Heading G4N. [Also in Division H4] In a Doppler system for detecting motion of a body in a guarded region a first alarm signal is generated if respective electrical counterparts of transmitted and received ultrasonic waves differ in frequency, and malfunction of or interference with the system is detected by generating a second alarm signal if the received signal level is below a predetermined value. In the Fig. 2 embodiment the output of receiving transducer 3 is amplified in stages 4, 5, 6 and fed to mixer 7 together with the transmitted signal counterpart from oscillator 1. Any difference frequency signal is amplified at 8 and applied via OR gate 21 and a line or radio link 20 to operate alarms 15a, 15b. The received signal is also picked off at 16, amplified, rectified and applied to amplitude discriminator 11 which feeds a second alarmoperating signal to OR gate 21, if the received signal is below a predetermined level due to malfunction of system stages preceding pick-off point 16 or due to blocking of the ultrasonic energy reaching transducer 3. Indicator 22 permits the identification of whichever signal operates the alarms, but in a modification (Fig. 1, not shown), the outputs of units 8 and 11 operate separate alarms, and gate 21 and indicator 22 are omitted. In further modifications the transmitted signal counterpart is derived from the ultrasonic energy received directly by transducer 3, and pick-off point 16 is between stages 3 and 4 or between stages 4 and 5.

Filed: 1966-12-13
Abstract: 1,113,568. Logic circuits. CORNING GLASS WORKS. 13 Dec., 1966 [16 Dec., 1965], No. 55676/66. Heading H3T. A logic circuit has inputs to the bases of transistors 14-20 whose emitter-collector paths are all in parallel, their emitters being joined to the base of one of a pair of emitter-coupled transistors 22-24, the base of the other of which is earthed. The whole unit may be formed on a single printed circuit board. With all inputs low (earth potential) the emitters of all the transistors are slightly below earth so that 22 is cut off and 24 conducts, setting the output line at earth (low output). A positive input to any one of 14-20 raises their emitters, turns on 22 and cuts off 24 so that the output line rises to the positive supply potential. The circuit operates as an AND or OR gate depending on the significance attached to high and low potentials. Transistor 22 isolates the output from noise at the input terminals. Other similar units may be connected at 36 for extra inputs. If similar circuits are interconnected at their OUT terminals an AND/OR function is obtained, as an output is obtained if the AND condition is satisfied for any one circuit.
