Title: Rubeola vaccine and process
IPC: A61K39/165
Filed: 1959-02-13
Abstract: A rubeola (measles) virus vaccine is produced by growing measles virus on monkey (i.e. any primate except man or lemurs) renal cell cultures, harvesting the live virus therefrom in a parenterally acceptable vehicle and destroying the infective capacity of the virus.  The preferred cell culture is that of renal cells from African vervet monkeys (Cercopithecus lalandi). Those from rhesus, cynomolgus and squirrel monkeys and those of simians, e.g. chimpanzee and baboons, may be used if substantially free from competitive latent viruses.  Propogation is by any well known tissue culture technique, e.g. Maitland minced tissue method, submerged culture of suspended cells or cultures of cells grown on glass (preferred).  Any complete tissue culture nutrient medium may be used, e.g. "medium 199," Eagles medium, medium NCTC 107 which may advantageously include about 5% to 10% of a filtered mamalian serum, e.g. calf serum (preferred).  The medium may also contain agents to prevent bacterial or mycotic growth, e.g. penicillin, streptomycin, mycostatin, parabens.  The cultures are incubated at about 25 DEG  to 40 DEG  C. (preferably 32 DEG  to 38 DEG  C.) for about 5 to 12 days and the virus is then harvested in a parenterally acceptable medium, e.g. those mentioned above, one of, these being used to replace the growth medium if unsuitable (e.g. contains mammalian serum).  Cellular debris is removed by centrifugation and the virus is inactivated by conventional means, e.g. by chemicals, e.g. formaldehyde, b -propiolactone, mustard oils or chlorine or by forms of physical energy, e.g. heat (45 DEG  C. for 30 hours or 25 DEG  C. for 200 hours), ultra-violet radiation, ionizing radiations (preferred), e.g. a -rays, cathode-rays, b -rays, g -rays or protons, the virus being present in variable conditions, e.g. in liquid or frozen suspensions, as a lyophilised powder in bulk or in sealed containers, e.g. of glass or low density polythene.  Preservatives, e.g. benzethenium chloride, parabens or "Merthiolate" (Registered Trade Mark) may be added to the final vaccine.

Title: Regeneration of solid granular contact material
IPC: B01J8/12
Filed: 1955-02-21
Abstract: In the regeneration of spent solid granular contact material containing a carbonaceous contaminent by burning with air, the contact material gravitates downwardly as a compact bed, air is introduced into the bed at a plurality of points uniformly distributed across the bed at a level intermediate the top and bottom of the bed and at least a portion of the air flows downwardly with the contact material and is removed as flue gas from the lower portion of the bed, and the distance between adjacent points of air introduction is less than 10 inches, preferably between 5 and 10 inches.  As a result of the closeness of spacing of the air inlets, the temperature differences at <PICT:0775815/III/1> different points across the bed are levelled out more rapidly as the solid descends, and thus a more even regeneration takes place and the burning capacity of the regenerator is increased.  As shown in Fig. 3, solids enter at 53 and pass down pipes 55, while air enters at 51, passing down pipes 56 to outlets 57; part of the air leaves at 59 and the remainder flows upward, leaving at 58. Cooling coils may be arranged just above the bottom of the bed.  A distributer for use at the bottom of the air introduction pipes 56 comprises four pipes 67, Fig. 8, and a central pipe 68 provided with an orifice plate 69.  An alternative form of distributer comprises a central vertical pipe 70, Fig. 11, an orifice plate 74, and a series of vertical slots in the pipe 70 communicating with triangular ears 71.  The regeneration may form part of a continuous process for the cracking or hydroforming of hydrocarbons in which contact material gravitates as a compact bed through reaction and regeneration zones and is then transferred upwardly in a stream of lift gas to the top of the reaction zone. Specification 689,369 is referred to.

Title: Improvements in or relating to methods and apparatus for high frequency induction heating
Inventor: BATCHELOR GEORGE DORSAN
IPC: H05B6/02
Filed: 1958-02-18
Abstract: 860,853. Heating crankshafts by induction. GENERAL ELECTRIC CO. Ltd. and PEARSON, F. Feb. 18, 1959 [Feb. 18, 1958]. No 5203/58. Class 39 (3). Apparatus for inductively heating the surface of an eccentric part on a crankshaft comprises a tank coil 4, a concentrator coil 5 and a workcoil 6 all carried by a table 3 which is connected to a main frame 2 by two pairs of parallel arms 9. The table is thus permitted to move in a circular path in a vertical plane corresponding to the eccentric movement of the part 1 of a crankshaft under treatment. The tank coil is mounted on an auxiliary frame 15 provided on the table 3 and is adjustable in a vertical direction by a motor 21 which moves a chain 16 connected to the frame at 17 and to a counter-weight 18. The position of the tank coil with relation to the concentrator coil is adjusted to control the output of the generator which is connected to the tank coil by flexible leads 7. The crankshaft to be treated may be mounted for rotation in the lathe in which it was originally machined and the lathe saddle is used to support the main frame 2; the saddle permits adjustment of the workcoil 6 in a longitudinal direction. The table 3 is coupled to the crankshaft by a clamping mechanism 10, and the workcoil 6, moving with the table, is constrained to follow the eccentric movement of the part 1 of the crankshaft as the latter is rotated about its axis. Limit switches 22, 23 for breaking the supply to the motor 21 are actuated by a striker 24 when the auxiliary frame 15 has reached its uppermost or lowermost positions and a relay ensures that the lathe is rotating the crankshaft before the power generator is switched on. A further relay ensures that cooling water to the workcoil is flowing before the power is connected. A process timer is specified, and to ensure that the generator cannot be switched on at too high a power level, the motor is controlled so as to return the tank coil to its position of minimum coupling each time the generator is switched off. The coils 4, 5 are also water cooled.

Title: Feed through capacitor
Inventor: GARSTANG WILLIAM WALK
IPC: H01G4/35
Filed: 1965-02-06
Abstract: 1,083,423. Feed-through capacitors. GLOBEUNION Inc. Feb. 6, 1965, No. 5246/65. Heading H1M. A feed-through capacitor 14 comprises a tube 24 of dielectric material surrounding a central conductor 16 and coated with a conductive layer 28 having slots 32 so disposed that the conductive layer is discontinuous along any line parallel to the axis of the capacitor. The arrangement shown, wherein diamond-shaped slots have their acute apices overlapping may be formed by winding a pair of opposite helical strips of similar width and pitch around the tube 28. The second strip may be separated from the first by a layer of dielectric material. Tube 24 is preferably formed from two or more portions having different dielectric constants, the boundaries between the portions enhancing the effect of the patterned electrode in breaking up the large resonant cavity associated with a tubular feedthrough capacitor. The inner surface of the dielectric tube is coated with a metal electrode (26) (see Fig. 2, not shown) in contact with the central conductor 16. This inner electrode may be slotted instead of the outer electrode, for example by raising the surface of the central conductor where the pattern is to contact the dielectric and leaving an air space between remaining portions of the conductor and dielectric. Alternatively, the inner electrode may comprise a single helix and the outer electrode a second oppositely wound helix, since the break-up of the resonance cavity is achieved as long as the radial projection of the two electrodes on to a surrounding surface has the required discontinuity. A single helix on only one electrode is accordingly ineffective. A C-ring 30 soldered to the outer electrode secures the capacitor to a chassis wall.

Title: Improvements in the production of the ammonium salts of penicillin
IPC: C07D499/14
Filed: 1947-02-25
Abstract: Ammonium salts of penicillin are prepared by adding an aqueous solution of ammonia, containing more than 20 per cent of ammonia slowly with stirring to an organic solvent solution of penicillin containing up to 10 per cent of a saturated aliphatic monohydric alcohol having less than 5 carbon atoms, such as methanol, ethanol or butanol.  The organic solvent is one in which ammonium penicillin is insoluble, which is immiscible with water and which has a specific gravity less than that of water, e.g. butyl acetate, amyl acetate, methyl isobutyl ketone.  Preferably, the quantity of ammonia used is not substantially in excess of the amount necessary to neutralize the penicillin present and the addition may be made in two or more successive portions so that any gummy material precipitated on the first addition may be separated.  The organic solvent solution of penicillin should preferably contain 2 per cent of methanol or ethanol or 5 per cent of n-butanol if wet and 5 per cent of methanol or ethanol or 10 per cent of n-butanol if dry.  In examples: (1) a solution of penicillin in n-butyl acetate containing 5 per cent of methyl alcohol is treated with ammonia and the resultant precipitate of ammonium penicillin is recrystallized from aqueous acetone; (2) a solution of penicillin in n-butyl acetate containing 10 per cent of butyl alcohol is treated as in (1); (3) the process of (1) is repeated, the addition of ammonia being made in successive portions; and (4) a solution of penicillin in n-butyl acetate containing ethyl alcohol is treated as in (1).
