Title: Improvements in or relating to immunisation against brucella infections
IPC: F16H63/34
Filed: 1964-05-19
Abstract: Brucella abortus is grown in liquid culture in a conventional medium. The culture is preferably performed under submerged aerated conditions, using a freeze-dried preparation of the strain McEwan 45/20 rough as an inoculum.  The culture procedure is similar to that of Specification No. 951,299 wherein the organism used is Strain 19 of Brucella abortus.  The culture is used, after treatment to kill the bacteria, to prepare a vaccine.ALSO:Vaccines for immunising against Brucella infections are prepared by growing Brucella abortus organisms in a liquid culture medium, treating the organisms so that they are killed, and incorporating the dead organisms in an adjuvant vaccine with a vaccine oil and at least one emulsifying agent, the organisms being of a strain which, when killed can stimulate immunity without producing agglutinogenic activity.  The vaccine preferably contains both a water-in-oil and an oil-in-water emulsifier, the latter comprising 2 to 10% by weight of the former, suitable emulsifiers being respectively mono-, di, or tri-oleate esters of mannide, sorbitan or mannitan or mixtures thereof; and polyoxyethylene derivatives of C12 to C20 fatty acid esters of polyhydric alcohols.  The preferred organism is that of the strain McEwen 45/20 rough, which is grown in submerged aerated culture, and killed by heating, e.g. to 50 DEG  to 75 DEG C., after which the organisms are centrifuged off, resuspended in water, and a preservative such as merthiolate being then optionally added.  This preparation may then be used directly to prepare the vaccine, by homogenising it with the emulsifiers and the oil, the latter suitably being pharmaceutical grade liquid paraffin.  The invention includes a method for immunising ruminants against Brucellosis by injection of the vaccine, preferably into the neck muscles.

Title: Character recognition
IPC: G06V10/28
Filed: 1973-05-01
Abstract: 1430145 Character recognition systems INPUT BUSINESS MACHINES Inc 1 May 1973 [2 May 1972] 20669/73 Heading G4R In a character recognition system the character is represented as an array of voltages, and groups of these voltages are compared with reference groups. The reference groups represent portions of reference characters. The order, or distribution, of the reference groups showing identity with the voltage groups is characteristic of the character to be recognized and of the corresponding reference character. The character is scanned magnetically or optically, e.g. by a matrix or a column of photo-sensors. The scanner output is passed to, for example, three thresholding units with different thresholds to accommodate characters of differing ink density and to compensate for edge effects. Each unit feeds a respective shift register matrix store. The voltages on corresponding groups of cells from each store in turn are passed to gating units. Each group comprises some of the voltages forming one row of the stored array, the voltages representing character and/or background points, and may comprise some voltages from other rows. If a group has voltages corresponding to a reference group a corresponding gating unit outputs a signal. For example, in the case of a character 0 appearing in one of the matrix stores as schematically indicated in Fig. 7A, a gating unit WD1 provides an output if a 1-bit appears in positions 3, 4, 5, 8, 9, 12, 13, 14 and an 0-bit in position 17 in any row. This occurs in rows 11 and 23. Similarly unit WD3 gives an output when there is a 1-bit in positions 3 and 14, and a 0-bit in positions 7-10 of the same row and in position 8 of the two adjacent rows. Each reference character is characterized by a particular distribution of groups, and for each such distribution a recognition circuit is provided. That shown in Fig. 5 detects the distribution WD1, WD4, WD3, WD3, WD9, WD9, WD1 which identifies a scanned character 0. When any one of the matrix stores contains a WD1 group in row 11 multiplexer 181 sets bi-stable 185 which increments counter 182. Prior to the counter stepping the multiplexer to terminal 2 the bi-stable is reset. If a WD4 group is in row 13 in any store the bi-stable is again set and the counter incremented, and so on. When the multiplexer reaches the end of its cycle the counter will have reached a predetermined count (here 8), whereas each counter in the other recognition circuits will not have reached this count, so that the scanned character is identified as being 0. Each counter output may be converted to a coded signal to be fed to a data processor and each is also connected to a circuit which provides an error signal disabling the recognition circuits if more than one counter reaches the predetermined count, i.e. if the recognition is ambiguous, or if no counter reaches that count, i.e. the character is unrecognizable.

Title: Improvements in carburetters
IPC: F02M17/14
Filed: 1919-08-25
Abstract: 158,591. Owers, J. C. Aug. 25, 1919. Spray carburettors.-The rate at which fuel is supplied during the induction stroke is either increased with the speed or is first increased and then reduced, which of these actions takes place being determined by the position of the throttle. A main air valve 2 closing a port 22 is lifted by suction, atomizing-air enters by an opening 29, and fuel is drawn from the float chamber through passages 16 past a check valve 19 to the fuel tube 15 in which is a needle 31 which rises with the valve 2 by the action of a spring 32. The area of the fuel orifice is thus increased until the upper end of the needle meets an axial rod 46, the position of which is determined by the position of a slot 49 in the cam-faced plug 5 operating the throttle. When the rise of the needle is thus checked, further suction on the valve 2 brings the seating 61 nearer the boss 60 on the needle, thus increasing the suction of the fuel; then as the action continues the boss 60 passes through the seating 61 and the suction on the fuel diminishes. The mixture of fuel and atomizing-air issues in the form of spray from between the discs 23, 24 forming the valve 2, and is carried by the main air current past the throttle 4. Dust-screens 62, 34 are provided, with gauze between them. The stem of the valve 2 has a dash pot 26 and its spring 27 fits at its upper end into helical grooves in an adjustable carrier 28. The nozzle can be adjusted vertically by hand by turning the cap 56 to allow for atmospheric changes or for starting cold. To prevent damage by back-firing a relief valve is provided on the induction chamber and a spring 33 will allow the valve 2 to be driven outwards through its seat.
