Patent GB-813882-A (GB)
Title: Vaccine products and methods of producing the same
IPC: A61K39/13
Filed: 1957-05-01
Abstract: A poliomyelitis virus vaccine comprises a sterile aqueous fluid containing poliomyelitis virus, e.g. Types 1, 2 and/or 3, which has been killed partly by the action of betapropiolactone which is substantially free from its decomposition products, and partly by treatment with ultraviolet light, the vaccine being free from living virus and capable of immunizing mammals against infection by living poliomyelitis virus.  The vaccine may be produced by subjecting aqueous fluid containing living virus to the actions of ultraviolet irradiation and betapropiolactone such that one of said actions is sufficient to kill a major proportion of the virus and the other of said actions being sufficient to kill all the residual live virus, neither action in the extent employed being alone capable of killing all the virus present.  Fluids containing Types 1, 2 or 3 virus may be thus treated and subsequently mixed to produce a trivalent vaccine.  The aqueous fluid containing living virus may be exposed to ultraviolet light to reduce the infectivity titre to a low value, and then to the action of betapropiolactone in a concentration of between 0.0002 and 0.0010 grams per millilitre of fluid.  A thin film of an aqueous fluid containing the living virus may be exposed to ultraviolet light at about 12,500 to 32,000 microwatts per square centimetre having a major proportion of energy at a wavelength of 2000 to 3000 Angstrom units for 0.5 to 2 seconds and to the action of betapropiolactone in a concentration of between 0.0002 and 0.0010 grams per millilitre, for a length of time sufficient to kill all the living virus present.  A film of the aqueous fluid of not greater than 100 microns thickness, which may have a pH of between 5 and 9 and containing from 0.0002 to 0.0010 grams per millilitre of betapropiolactone may be exposed to about 25,000 microwatts per square centimetre of ultraviolet light at a wavelength of 2537 Angstrom units for 0.5 to 2 seconds, and then held, e.g. at 20 DEG to 40 DEG  C., for a time sufficient to enable the betapropiolactone still in the fluid to kill all the remaining virus.  The vaccines, which may be diluted with suitable diluents such as sterile Hank's solution, sterile saline solution and sterile distilled water, may be administered subcutaneously, intradermally, or intramuscularly, and may contain germicidal and/or stabilizing agents, e.g. benzethonium chloride.  Specification 655,198 and U.S.A. Specification 2,725,482 are referred to.

Title: Converting hydrocarbon oils
Filed: 1932-05-17
Abstract: <PICT:0401694/III/1> Oils are cracked to obtain products of low boiling-point by heating a condensate oil to a high cracking temperature e.g. 1000--1050 DEG  F. under pressure, passing the products into a reaction chamber where they are cooled by contact with an oil at lower temperature, and wherein separation into liquid and vapour occurs, passing the vapours to one or more digestion zones maintained at cracking temperature and thence to a fractionating zone in which a final light distillate is separated out leaving a reflux condensate which provides the condensate oil used as the starting material.  Crude oil is cracked at low temperatures e.g. about 825 DEG  F. by passage through a coil 1 and the products are passed through a pipe 16 into a tower 2 where they mix with and cool the products formed by cracking a condensate at 1000--1050 DEG  F. in a coil 3.  The vapours produced are passed through a line 20 into digestion towers 4, 5 and the products are fractionated in a tower 6 from which the final products pass off through a line 31 while the reflux forming in the bottom of the tower is passed to the coil 3. Reflux is obtained by either returning through a pipe 32 condensate formed in a heat exchanger 7 through which the crude oil is passed, or by condensing the vapours in a coil 8 and recycling part of the condensate from a receiver 9 by a pump 50 and line 51.  Residues in the towers 4, 5, may be passed by a pump 26 to the tower 2, and part of the reflux from the tower 6 may be pumped through a cooler 44 into the tower 5.  Liquid residues collecting in the bottom of the tower 2 are withdrawn as fast as formed.  The temperature of the towers 4, 5 is maintained about 875--870 DEG  F.

Title: Improvements in or relating to the preparation of sand for moulding
Inventor: MCDOWALL ROBERT
IPC: B22C1/22
Filed: 1957-05-03
Abstract: Production of resin coated sand particles for use in the production of shell moulds comprises, mixing the sand with a thermosettable phenol-formaldehyde condensation product, containing free steam-volatile phenol, at a temperature in excess of 100 DEG C. and above the melting point of the condensation product, adding water in an amount sufficient to remove the free phenol by vaporisation in association with the steam produced, continuing to mix the sand and condensation product until discrete sand particles individually coated with resin are formed, and adding hexamethylene-tetramine to the mixture in an amount sufficient to convert the condensation product to a thermoset resin on subsequent heating, during, or subsequent to, the water addition.  Where hexamethylene-tetramine is added prior to the formation of discrete sand particles the temperature of the mixture is maintained at least at that obtaining at the time of addition of the hexamethylene-tetramine until particles are formed.  A phenol-formaldehyde condensation product containing a molar ratio phenol:formaldehyde of 1:0.4 to 1:0.9 preferably 1:0.72 to 1:0.76 containing 2-10% wt. of free steam-volatile phenol is added in an amount of 2-10% wt. to sand preheated to a temperature of 120-160 DEG C., in a mechanical mixer. Sufficient water, preheated, if desired, to maintain the temperature of the mix, is added, and to facilitate rapid evaporation external heating by a steam jacket, a radiant heater, or hot air may be applied.  Hexamethylene tetramine in amount from 5-20% wt. of the resin is added either as such subsequent to the water, or as a solution therein, and the temperature of the mix is maintained together with continued stirring until discrete particles are formed. Any small aggregates may be finally broken down by tumbling in a rotary drum.  Specification 753,163 is referred to.

[Class 38 (iv)] Synchronizing.-In apparatus for automatically closing a paralleling switch between two A.C. systems when the beat frequency and phase difference are favourable, the switching impulse is further timed by means taking into account the rate of change of beat frequency. Fig. 1 shows a paralleling switch 3 for the systems 1, 2 actuated by a relay 4 under the control of known apparatus 5 which is fed through transformers 6, 7 and which energizes the relay under favourable conditions as regards beat frequency and phase difference. The means for modifying the action of apparatus 5 in dependence upon the rate of change of beat frequency, comprise idly running fly-wheel machines 10, 12 and 11, 13, the abnormal line currents of which, when either system ,is accelerating, varies the settings of regulators 8, 9 and modifies the phase of the voltages fed by transformers 6, 7 to the apparatus and thus the point in the beat cycle at which relay 4 is energized. The circuit of relay 4 may be interrupted automatically at high beat accelerations to avoid closure of the switch under such conditions. Tn another arrangement, one or both regulators are actuated by a differential gear having one shaft driven by a synchroscope at beat frequency and another carrying a fly-wheel and normally idly running at beat frequency.
