IPC: C08F10/00
Filed: 1945-09-24
Abstract: Propylene is separated from ethylene by contacting a gas containing the two with a boron fluoride-sulphuric acid mixture, whereby the propylene is polymerized selectively (see Group IV). A suitable catalyst mixture contains from 5 to 50 per cent. by weight of boron fluoride the remainder being sulphuric acid ranging in strength from about 40 per cent. to about 85 per cent. but any concentrated solution of boron fluoride in sulphuric acid of this strength may be used.ALSO:<PICT:0584121/IV/1> Propylene is separated from ethylene by contacting a gas containing the two with a boron fluoride-sulphuric acid mixture, whereby the propylene is polymerized selectively.  A suitable catalyst mixture may contain from 5 to 50 per cent by weight of boron fluoride, the remainder being sulphuric acid ranging in strength from about 40 per cent to about 85 per cent, but any concentrated solution of boron fluoride in sulphuric acid of the above strength may be used.  The gas mixture is best introduced into a body of a counter-flowing stream of the catalyst through suitable dispersing nipples, such as porous thimbles.  The operation is preferably conducted at pressures between atmospheric and 150 lbs./sq. in. and at temperatures between about 60 DEG  and 125 DEG F.  In the Figure the catalyst mixture of sulphuric acid and boron fluoride is introduced into the top of two scrubbing towers 1 and 2. The gas containing ethylene and propylene is introduced into the bottom of tower 1 where the bulk of the propylene is polymerized. The residual gas then leaves at the top of the tower and is conducted to the bottom of tower 2 where any residual propylene is removed. The catalyst carrying polymerized propylene leaves the bottom of towers 1 and 2 and discharges into the separators 9 and 14 respectively.  The polymerized propylene is withdrawn from the upper portion in the separator and the catalyst withdrawn from the bottom. The propylene free gas is taken off at the top of tower 2 while the catalyst can be recycled to the scrubbing towers or removed from the system.

Abstract: 690,803. Making chenille. BRADITCH, M. Sept. 27, 1948 [Sept. 26, 1947], No. 25117/48. Class 142(iv) Twisted core chenille is manufactured on a machine of the type in which the core threads are advanced by endless driving threads or ribbons having a continuous motion. A plate 6 is rotated by an electric motor through suitable transmission 4. Four pulley wheels 9, 10 mounted on the plate carrying the driving threads 11, 12 and two of the pulleys engage a stationary gear 25 and are rotated when the plate 6 rotates. Core warp threads 29, 30 unwind from spools 20, 21, also carried by the plate 6, and pass through guides 13, 14 and are driven by the threads 11, 12. Chenille weft spools 16 are mounted on two discs 15 which rotate about the guides 13, 14 due to their engagement with a friction ring 24 carried by a stationary ring 23. The weft threads pass through guides 22 and wind round the core and driving threads. The core threads, after passing between guide rollers 27, 28, are wound on a take-up roller which does not rotate about the longitudinal axis of the plate 6 so that the core threads become twisted together and hold the weft threads whose loops are cut by a knife mounted at the point of exit from the rollers 27, 28.

Title: Improvements in or relating to the preparation of fractions from serum
IPC: C07K16/06
Filed: 1951-10-26
Abstract: Sera are treated by the addition of disstilled water which precipitates a fraction with an immunizing function; when this fraction is separated, a fraction exercising a sensitizing function is isolated from the residual liquid, say by the addition of further distilled water.  The volume of distilled water added to the serum in order to precipitate the immunizing fraction may equal 9 times the volume of the serum; the sensitizing fraction is precipitated by the addition of distilled water equal to 30 times the volume of the serum.  The serum treated may be obtained from animals which have been treated as follows, to increase the content of the immunizing fraction:-(a) the intravenous injection of gelatin; (b) parenteral injection or administration through the bones of haemoglobin or its derivatives, haematin or its derivatives or blood taken from the animals themselves after lysis of its globules.  The animals used may be horses, pigs or cattle.  The sera may be obtained by pressing animal organs or tissues, the resulting juices being prepurified by centrifuging or filtration.  The products may be used in the preparation of culture media for microbes and virus, or in the preparation of sera or vaccines.

Title: Improvements in and relating to fluid metering valves
IPC: G01F3/16
Filed: 1947-09-15
Abstract: 635,737. Valves actuated by auxiliary valves. BAILEY, S. R. Sept. 15, 1947, No. 25174. [Class 135] In a flushing valve of the kind comprising a cylindrical chamber 1 with a lateral inlet 3 and an axial outlet 4, a hollow piston 9 which is slidable in the chamber and carries a main valve 9a to control the outlet and also houses a pilot relief valve 11 which, when opened, allows liquid to escape from the upper side of the piston, a bleed allowing liquid to flow from the inlet to the upper side of the piston to build up pressure and so close the main valve, and means, such as a handle 8, to unseat the relief valve to lower the pressure above the piston so that the inlet pressure will raise the piston and open the main valve which stays open until pressure has built up again above the piston, the piston carries a pair of laterally-extending, metal annular fins or flanges 12, 13 which slide against the wall of the chamber 1 and are slit or slotted to provide the bleed passage. The flanges are retained in position by a screw-cap 15 which is apertured to allow venting of the liquid above the piston when valve 11 is opened. The pilot valve carries a telescopic extension 11a which is engaged by a spring-loaded plunger 7 to tilt the pilot valve when the handle 8 is tilted. The lowered pressure above the piston ensures the telescoping of the extension 11a so that it clears the plunger 7. The main valve carries a number of depending guide fingers 18a through the spaces between which the plunger 7 can reciprocate, and as the fingers are spaced from the wall surrounding the outlet, a depending machined skirt portion 18b constituting a guide for the valve is also provided. Specification 529,659 is referred to in the Provisional Specification.
