Title: Brucella vaccines
Inventor: CAMERON JOHN
IPC: C12N1/20
Filed: 1964-05-26
Abstract: Avirulent strains of Brucella abortus are cultivated in a nutrient medium containing an adequate carbon source which is fructose, or contains at least 0.1% w/v. fructose in respect of the medium, or at least 2.5% w/w. fructose in proportion to the total carbon source, the culture then being freeze dried to give a living vaccine of the micro-organism. The preferred strain of organism is S.19; the medium is of conventional constitution regarding components other than fructose, the latter suitably being present in about 4% w/v. concentration.  Alternatively, the carbon source may be, e.g. about 4% w/v. of a 3:1 by weight mixture of glucose with fructose. Preferably sucrose, about 5% w/v. is added to the culture before freeze drying, as as a stabilizer.  Cultivation in the presence of fructose is said to increase the number of viable organisms in the freeze-dried product, and to improve its stability on storage.ALSO:Living Brucella abortus vaccines are prepared by cultivating a non-virulent strain thereof in a nutrient medium, having an adequate carbon source which is fructose or contains at least 0.1% w/v. fructose in respect of the medium, or at least 2.5% w/w. fructose in proportion to the total carbon source, and freeze-drying the resulting culture.  The preferred strain is the S.19 strain.  A suitable additional carbon source is glucose. Before freeze-drying, sucrose is preferably added to the culture, to about 5% w/v. concentration, to improve the stability of the vaccine.  The presence of fructose as a carbon source is said to increase the number of viable organisms in the vaccine after freeze-drying, and to improve its storage stability.

Abstract: 1,153,142. Tubular heat exchangers. COURTAULDS Ltd. 24 Aug., 1966 [25 May, 1965], No. 22153/66. Heading F4S. A heat exchanger comprises tubes of flexible thermoplastic film and consists of an outer tube 3 carrying a liquid to be cooled and one or more coolant carrying tubes 6 disposed within the outer tube. An additional coolant e.g. atmospheric air, may surround the outer tube. Figs. 3 and 4 show a heat exchanger for cooling and crystallizing liquids, comprising inner and outer flattened coaxial polyethylene tubes 8 and 9, the coolant liquid flows into tube 8 through a narrow tube 18 and distributer 19 (see also Fig. 5), and the liquid to be cooled flows into space 27 between the tubes 8 and 9 via tubes 32 and fish tails 28 and 29. The tubes 8 and 9 and the distributer 19 are made from sheets of polyethylene, 10 and 11, 14 and 15, and 20 and 21, welded together along their vertical edges, their upper ends being supported by rods 12 and 13, 16 and 17, and 22 and 23, respectively. The lower edges of sheets 20 and 21 are welded together at spaced intervals to provide a slotted outlet for the distributer (see Fig. 5). The lower end of tube 8 has a liquid tight seal over a stand-pipe 38 through which the coolant flows out and the lower end of tube 9 communicates with a tank 36 for collecting crystals and/or cooled liquid. The space 27 may be sub-divided into separate passages by welding. Two pinch rods 33 and 34 press the sheets of thermoplastic together, giving an even distribution of liquid across the tubes and sealing the space 27. In a second embodiment three inner tubes are provided within one outer tube. The heat-exchanger may be used for crystallizing Glauber Salts or making ice. The supply of coolant may be interrupted to allow crystals to be freed from walls.

Title: Improvements in or relating to door lock structures
IPC: E05B65/32
Filed: 1947-08-11
Abstract: 639,333. Door latches. HOUDAILLE-HERSHEY CORPORATION. Aug. 11, 1947, No. 22232. Convention date, March 12. [Class 44] A door latch, e.g. for an automobile comprises a supporting plate carrying a pivoted latch bolt, retracting means operable by an outside handle, an inside handle rotatable in one direction to retract the bolt and in the other to block the retracting means of the outside handle, and a locking lever movable by an outside key-lock mechanism to block the retracting means of the outside handle. The latch parts are mounted on two plates 10, 100 at right angles. The outside handle spindle is carried in two followers 11, 12, Fig. 1, on the plate 10 of which one 11 abuts a fixed bracket 13 and the other 12 is engaged by a spring loaded lever 14 so that the spindle is held against rattling by a scissors grip between the followers 11, 12. The latching lever 21 is operated by either the surface 14b of the lever 14 or the nose 19c of a lever 19 operated by the inside handle through a link 75. The latch is carried on the outside of the plate 100 and comprises a catch 21c on the latch lever 21 and a rotatable locking bolt 35, Fig. 5, pivoted at 39 and carrying on the inside a lever 42, Fig. 2, pivoted at 40. The lever 42 is spring loaded in an anticlockwise direction by a spring 43 and carries a lug 42a co-operating with a serrated surface 47a on a lever 47. The end 48 of the lever 47 bears downwardly on the top of the latch plate 21 when this is in the latching position. As the door is slammed, the catch part 21c is lifted and allowed to fall by the keeper and the arm 37 of the bolt 35 engages the surface 61 to tilt the bolt into the position of Fig. 5. The arm 42, carried on the pivot 40 turns in an anticlockwise direction until the lug 42a contacts the rack 47a it being then retained to secure the bolt 38 in the locked position. The bolt is released by rotation of the latch plate 21 which allows the lever 47 to drop. Rotation of the lever 21 by the outside handle may be prevented by a locking lever 25, Fig 1, operable by an outside key-lock to block the movement of the lever 14 or by a hooked extension 19a movable by the inside handle into a position where it engages the nose 11d of the follower 11. The lever 19 is connected by a link 75 to a lever 73 connected to an inside handle 71 and retained in two alternative positions by a spring 82 engaged in recesses 79, 80. The locking action of the lever 25 may be cancelled by slamming the door or by turning the inside handle, the lever 21 contacting and displacing the lever 25.

Title: Separating cyclopentadiene from benzole fronts
IPC: C07C7/148
Filed: 1959-06-29
Abstract: The Diels-Alder addition-product of cyclopentadiene and maleic anhydride, i.e. 3,6-endomethylene-D 4-tetrahydrophthalic anhydride, is obtained by passing vapours of benzole forerunnings into a solution of maleic anhydride in an inert solvent, such as toluene, xylene or carbon tetrachloride, the temperature of the solution being maintained sufficiently high that condensation of the carbon disulphide vapours, and other non-reactive constituents of the forerunnings, does not occur.  In an example, the vapours of benzole forerunnings at about 60 DEG C. are passed into a solution of maleic anhydride in toluene, maintained at 60 DEG C. to 70 DEG C.  The solution is then cooled to 0 DEG C.; and the crystals which separate are filtered off, and recrystallized from petroleum ether.

Title: Improvements in or relating to high-frequency ovens
IPC: H03B7/10
Filed: 1958-07-11
Abstract: 843,322. Generating oscillations. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 11, 1958 [July 13, 1957], No. 22321/58. Class 40(5). In a high-frequency oven in which the oscillatory circuit is excited by a gaseous discharge tube, the ignition pulses for the tube are timed so that the additional charge fed to the oscillatory circuit is added in phase with the charge already circulating in the circuit. Gaseous discharge tube 1, Fig. 1, is fired by ignition pulses from thyratron 19 in turn fired by pulses from relaxation generator 13, 14, 15. A sawtooth voltage from capacitor 15 is fed to the control grid of valve 13 by potential divider 23, the valve being normally cut off. A sinusoidal voltage from coil 24, coupled to oscillatory circuit coil 4 is added to the sawtooth voltage, the cut-off bias being overcome when the lower end of coil 4 is positive. This point corresponds to time t 1  &c., Fig. 2a, which shows the resultant anode voltage 26 of tube 1, the direct voltage supplied by charging capacitor 8 being shown by curve 25. When tube 1 fires, capacitor 8 discharges into circuit 2 through tube 1 the charge adding to that present in capacitor 3 as shown in Fig. 2a. Since the amplitude of the sinusoidal voltage from coil 24 increases as load 7 is decreased, the firing rate of thyratron 13 increases, but as this is undesirable, the sinusoidal voltage is rectified at 31 to increase the negative bias on valve 13 as the load decreases so that the firing rate remains constant.
