Title: Determination of Bacteria
Filed: 1967-08-11
Abstract: 1,161,920. Bacteriological testing. CASTROL Ltd. Aug. 11, 1967 [Aug.15, 1966], No.37074/67. Heading C6F. The concentration of viable bacteria in a medium is determined by an indicator device having thereon or therein a substance (or substances) capable of undergoing a colour change in the presence of bacteria which substance is present in different concentrations or in different parts of the indicator device, such that when the device is immersed in or otherwise brought into contact with a medium to be tested, the concentration of viable bacteria present in the medium is indicated by the extent of the colour change which occurs in the various parts of the indicator device. The indicator device may be employed in the determination of bacteria in soluble oils, jet engine fuels and other petroleum products, and dairy products, and in the detection of urinary tract infections. In the case of non- aqueous media such as engine fuels, a measured quantity of the material to be tested is mixed with equal quantity of Ringer's solution and the aqueous layer is subjected to the testing. Since not all the bacteria will pass into the aqueous phase, a correction factor has to be applied to the results of the test; this factor can be ascertained for any particular type of medium by filtering a measured quantity and counting the extracted bacteria. A piece of absorbent material such as filter paper is marked off into sections by parallel lines and every alternate section is impregnated with a solution of methylene blue and albumin (or sodium alginate), the concentration of methylene blue in the solutions applied to the different sections progressively increasing as follows: 1:8, 000; 1:16, 000 ; 1:24, 000; 1:32, 000 and 1: 40, 000, respectively. The impregnated paper is then dried for 30 minutes at 65 C. to "fix" the methylene blue by rendering the albumin insoluble in water. After drying, the paper is provided with a backing of stiffer material and cut into strips at right angles to the lines separating the sections impregnated with the various solutions. In use, a strip is placed in the medium under test for a standard time (usually between 10 and 20 minutes) and the extent of decolourization observed. A quantitative indication of the concentration of viable bacteria can be ascertained by comparison with a colour standard prepared on the basis of calibration tests. In order to facilitate reading the results of a test, a sign such as the word "contaminated" may be printed in the coloured areas of the strip in a colour substantially matching the colour of the lightest coloured area. In this case the darkest area to be decolourized will be indicated by the darkest area in which the sign become visible. Examples relate to the detection of Escherichia coli, Staphylococcus, Bacteroides sp, Pseudomonas sp, Protevs sp, Streptococci and unspecified mixed cultures of bacteria with the aid of the methylene blue test paper in concentrations ranging from 10<SP>1</SP> (one square decolourized) to 109 (five squares decolourized) viable organisms per ml.

Title: Addressable gas-discharge devices
IPC: H01J11/28
Filed: 1971-08-10
Abstract: 1357562 Gas discharge display panels FUJITSU Ltd 10 Aug 1971 [10 Aug 1970] 37582/71 Heading H1D Display apparatus comprises a gas discharge panel with insulating walls 21, 22 carrying electrodes 19, 20 and crossed conductor arrays 16, 17 and circuitry connected to the arrays operable to produce cyclotron resonance of electrons to establish a glow discharge at any selected conductor intersection, by producing at that intersection crossed magnetic and microwave electric fields. The panel includes continuous electrodes 19, 20 insulating plates 13, 14 and ferromagnetic films 18 on which the conductors 16, 17 are mounted. A microwave signal is applied across electrodes 19, 20 and a potential is applied to selected conductors. The potential is such that the resulting current and magnetic field produce an electron rotational frequency equal to the frequency of the microwave signal. Under these conditions cyclatron resonance occurs and the microwave power required to initiate a discharge is 1/100 that required if the magnetic field has other values, hence a discharge occurs at selected intersections. The variation of power required with field is very great hence the field due to current in one conductor alone is insufficient to produce a discharge. Moreover a discharge remains localized since charged particles are not given any net movement parallel to the plates 13, 14. The discharge can be maintained with the same microwave power but a lower field hence lower sustaining currents can be applied thereby producing a memory effect. The discharge is erased by further reducing the field. Sustaining D.C. current can be applied to all of the conductors and discharges produced and erased by positive and negative pulses. In other embodiments the sheet electrode is replaced by a strip electrode extending in zig-zag or serpentine fashion over plate 13; the electrodes 16, 17 are on the outside of plates 13, 14 and electrodes 19, 20 on the inside, the latter may be replaced by crossed conductor arrays.
