Title: Improvements in or relating to the catalytic polymerization of unsaturated organic compounds
IPC: C08F36/04
Filed: 1940-08-07
Abstract: Unsaturated organic compounds which can be polymerized in aqueous emulsion in presence of an organic or inorganic peroxy-compound are polymerized in the presence of a peroxide of a cyclic ether having two oxygen atoms in the ring.  Cyclic ethers specified are 1 : 4-dioxane; 2 - methyl - 1 : 4 - dioxane; 2 : 6 - dimethyl - 1 : 4 - dioxane; 2,3,5,6 - tetramethyl - 1 : 4 - dioxane, 2,2,5,5 - tetramethyl - 1 : 4 - dioxane, 2,3 - dimethyl - 1,4 - dioxane; 2,5 - diethyl - 1 : 4 - dioxane, 2,6 - dimethyl bis - trimethylene dioxide; 1 : 3-dioxolane, 2-methyl-1 : 3-dioxolane and 2,2-dimethyl-1 : 3-dioxolane.  The peroxides are obtained by prolonged agitation in the presence of oxygen or exposure to light or ultra-violet light or by action of hydrogen peroxide or treating with oxygen under pressure.  The peroxide may be present in solution in the cyclic ether from which it has been derived.  Unsaturated organic compounds specified are butadiene and vinyl chloride.  Gelatine and palmitic acid base soap may be present in aqueous emulsion polymerization. Dioxanes are prepared by either dehydration of glycols in the presence of phosphoric acid or saponification of polyethylene chlorhydrins.  Dioxolanes are obtained by reacting an aldehyde or acetone with a glycol in the presence of an acid.  Specification 532,158 is referred to.
Patent GB-714427-A (GB)
Title: New antibiotics and methods of preparation thereof
Inventor: THAYSEN AAGE CHRISTIAN
Filed: 1951-05-30
Abstract: A new antibiotic "comirin" is produced by growing the micro organism Bacterium antimyceticum n. sp. in the presence of oxygen in a medium containing organic and/or inorganic nitrogen, and extracting "comirin" from the culture.  Aerobic conditions and a medium also containing carbohydrate, e.g. one or more mono- or di-saccharides such as glucose or saccharose is necessary for good yields.  A preferred medium contains 0.5 per cent peptone and 0.5 per cent saccharose; the pH is adjusted to 6.2 and cultivation is as 22-30 DEG C., especially 22-28 DEG  C.  Inorganic nitrogen sources are ammonium phosphate and ammonium citrate.  Comirin is isolated by extracting the culture twice with n-butanol with stirring 3 hours.  The butanol extracts are centrifuged and then saturated with 5 per cent sodium chloride.  The saline layer contains the comirin which is centrifuged out, washed with aqueous sodium chloride and extracted in 50 per cent aqueous pyridine.  Amyl acetate is added to precipitate the comirin which is washed with acetone.  Further purification is obtained by repeating the aqueous pyridine treatment, dissolving the so-purified comirin in glacial acetic acid and adding ether.  Comirin is a peptide containing 12 per cent nitrogen, it is precipitated by protein precipitants and yields amino acids such as glycine and serine on acid hydrolysis; it is active against many specified fungi and yeasts; it is strongly haemolytic; stable to heat and acid, unstable to alkali; considered to have strong surface-active and colloidal properties; soluble in aqueous-organic solvent and aqueous salt mixtures including aqueous "Tween 80" (Registered Trade Mark); in ethylamines and in formic, acetic and propionic acids; insoluble in anhydrous alcohols, acetone, dioxane, ether, ethyl acetate, amyl acetate, chloroform, benzene and light petroleum; it is dialysable through "Cellophane" (Registered Trade Mark) from aqueous pyridine solution; RF values given. Comirin may be used as a fungicide for general use or as an ointment for therapeutic use (see Group VI).ALSO:An antibiotic "comirin" produced by growing the micro-organism Bacterium Antimyceticum n.sp. in a suitable medium (see Group IV(b)) is a fungicide for general or medicinal use. Aqueous sprays may be used for general use and ointments for medicinal use.  An example is given of an ointment containing 4 per cent water agar, liquid paraffin and an aqueous solution of comirin containing 5 per cent of the polyoxyethylene derivative of sorbitan mono-oleate "Tween 80" (R.T.M.).

Title: Colour television signal processing apparatus
IPC: H04N9/09
Filed: 1965-03-25
Abstract: 1,091,126. Colour television. RADIO CORPORATION OF AMERICA. March 25, 1965 [April 3, 1964], No. 12779/65. Heading H4F. The invention relates to a colour television camera system in which a luminance signal is derived independently of red, green and blue colour signals which are matrixed in the customary fashion to obtain I and Q signals for transmission together with the luminance signal. In order to ensure that the luminance signal is in proper relationship with the I and Q signals, the three signals are applied to a further matrix circuit, similar to that used in a receiver, to re-derive red, green and blue signals. These are then applied to a circuit, Fig. 2, in which they are first individually restored to a fixed black level by clamps 21, 22, 23 and then applied to two groups of transistors 24, 26, 28 and 25, 27, 29 by means of which there are selected respectively the instantaneous minimum and maximum signals B and W. The minimum signal is applied to control the black level of all of the original signals derived from the camera, i.e. the original luminance and red, green and blue signals, whilst the maximum signal is applied in a similar manner to control the gain of channels for the original signals. Transistor 33 and 34 comprise blanking stages for eliminating spacious components introduced during the blanking intervals. Transistors 38 and 41 comprise gate stages for applying signals B and W alternately to a monitor cathode-ray tube each for the duration of two scanning lines.
