Title: Poliomyelitis vaccine products and methods for preparing the same
IPC: A61K39/13
Filed: 1955-10-05
Abstract: A poliomyelitis vaccine product is prepared by absorbing the virus antigen from a killed aqueous vaccine containing at least one strain of human poliomyelitis antigen on to aluminium phosphate gel, separating the latter with the absorbed antigen and resuspending in water or a physiological salt solution.  The suspension is substantially free from proteins.  In preparing the starting vaccine, trypsinized macerated monkey kidney tissue is inoculated with the virus the mixture is incubated, and the living virus in the harvested fluid is inactivated with formaldehyde, ultra-violet radiation, &c. Absorption of the antigen is effected below 40 DEG C., preferably at 0-10 DEG C.  The resuspension may contain 0.2-8 mg./ml. aluminium phosphate, and benzethorium chloride in concentration 1 to 10,000-50,000 as a preservative.  Other antigens, e.g. tetanus, diphtheria, pertussis may also be absorbed in the aluminium phosphate.  Tabulated results show that the original vaccine is less potent than the original vaccine plus aluminium phosphate and still less potent than the separated and resuspended vaccine product.

Title: Process for the production of porous artificial compositions
IPC: C08J9/28
Filed: 1926-11-13
Abstract: 261,409. Kunztharzfabrik & Dr. F. Pollak Ges. Nov. 14, 1925, [Convention date]. Urea-aldehyde condensation products.-Cloudy porous artificial masses are obtained by diluting with water the liquid initial condensation products of urea or its derivatives with formaldehyde until the water content is about 60-65 per cent, then forming a gel and allowing it to harden with inclusion of the water, and finally removing the water, first at a temperature below 30‹ C. and then at a higher temperature. An organic liquid such as alcohol may replace the water, but then at a lower specified concentration. It is stated to be possible to adjust the size of the pores. Liquid, solid, or fibrous organic or inorganic materials may be incorporated in the products during or after their manufacture. According to the examples, (1) a formaldehyde-fixing medium of the kind described in Specification 193,420 is added to a hydrophile condensation product prepared from urea and formaldehyde by the process described in Specification 213,567, and a little concentrated formic acid is stirred in; after standing some time, the mass is kept at 40‹ C. in a mould until it solidifies, when it is removed and hardened by keeping in a cool place, giving a white composition resembling meerschaum; by expelling in vacuo a proportion of water from the liquid condensation product before subjecting it to the preceding treatment, products are obtained which are less cloudy or even opalescent; (2) the hydrophobe condensation product prepared from urea and formaldehyde by the process described in Specifications 213,567 and 248,729 is mixed with alcohol as a dispersion medium, and after the addition of phosphoric acid, allowed to gelatinize in a mould at 50‹ C. ; the gel is then removed and allowed to stand at a temperature below 20‹ C. until the bulk of the alcohol and water have evaporated, when the mass is hardened by heat. Specifications 187,605 and 208,761 also are referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that aldehydes in general may replace the formaldehyde, and that instead of acids may be employed acid salts, ammonium salts, neutral salts of strong acids with strong bases, albumen-precipitating agents and the like. This subject-matter does not appear in the Specification as accepted.

Title: High-tension air-blast circuit-breaker
IPC: H01H33/56
Filed: 1958-09-11
Abstract: 841,341. Gas-blast switches. ALLMANNA SVENSKA ELEKTRISKA A.B. Sept. 11, 1958 [Sept. 12, 1957], No. 29107/58. Class 38 (5). In an air-blast circuit-breaker in which the movable contact 3 is held in the open position against a spring 5 by the air-pressure in the breaking chamber 2, undesired operation upon decrease of air pressure is prevented by arranging for the normally-fixed contact 4 to move so as to maintain separation between the contacts. The contact 4 is mounted on a tube on a differential piston 18 and is biased open by a spring 20. With the breaker closed, Fig. 1, contact 4 is maintained in raised position by compressed air from container 2 occupying space 19 beneath the piston 18, and is locked by a hook pin 21. Space 6 is also under pressure through the moving contact 3, channel 13 and valve 10, pistons 8, 9 being raised. To open, these pistons are depressed by air supplied to space 7, allowing space 6 to exhaust to atmosphere through channel 14 and air pressure to raise contact 3 and exhaust through valve 11. Subsequently leakage of air through channel 15 allows valve 11 to close and air passes through channel 22 to unlock the pin 21, Fig. 2. In this position, if the pressure in container 2 decreases sufficiently, spring 20 depresses the contact 4, the arrangement being such that contact 4 moves faster than contact 3 to maintain the breaking gap. Decrease of pressure in channel 22 then allows the pin 21 to lock the piston 18, to prevent reclosure if the containerpressure again increases. A fault signal or indicator can be actuated by the piston 18.
