Title: Improving olefin polymer dye receptivity
IPC: C08G73/00
Filed: 1966-05-10
Abstract: Shaped articles comprise a mixture of a crystalline olefin polymer and 1 to 25 per cent based on the weight of olefin polymer of a basic nitrogen containing polycondensate of epichlorohydrin with a bis-secondary amine and a diphenolic compound.  The articles may be textile fibres and filaments, tapes or films.  The olefin polymer may be polypropylene.  The polycondensate may be prepared from dialkyl alkylenediamines, piperazine, 2-methyl piperazine or 2,5-dimethyl piperazine and 2,2-bis(4-hydroxyphenyl)propane, pyrocatechol, resorcinol, hydroquinone or 4,41-dihydroxy diphenyl methane.  The polycondensates may be rendered water-insoluble by treating the articles with epoxy compounds, isocyanates, aldehydes, halogens or divinyl benzene.  The polycondensates are said to improve the dyeability of the olefin polymer articles, which may be further improved by treatment with an acid.  In examples epichlorohydrin and piperazine are reacted with (1 and 2) bisphenol A and (3) hydroquinone in methanol with the addition of sodium hydroxide in the later stages of the reaction.  The products are mixed with polypropylene, calcium stearate and titanium dioxide and the resulting compositions melt spun into fibres which are stretched, treated with a solution of ethylene glycol diglycidyl ether and dyed.ALSO:Articles such as fibres, filaments, films and tapes made of compositions comprising a crystalline olefin polymer and 1 to 25 weight per cent based on said polymer of a polycondensate of epichlorohydrin, a bis secondary amine and a diphenolic compound or diglycigyl ether thereof, may be dyed with acid, metallised and dispersed dyestuffs.  The olefin polymer may be polypropylene and the polycondensate may be derived from dialkyl alkylenediamines, piperazine, 2-methyl piperazine or 2, 5-dimethyl piperazine and 2,2-bis(4-hydroxyphenyl) propane, pyrocatechol, resorcinol, hydroquinone or 4,4\sv-dihydroxy diphenyl methane.  The polycondensates may be rendered water-insoluble by treating the articles with epoxy compounds, isocyanates, aldehydes, halogens or divinyl benzene, and dyeability may be further improved by treating the articles with an acid.  Dyeing with acid and metallised dyestuffs may be effected in the presence of ammonium acetate and a surface active agent, e.g. an alkyl phenol/ethylene oxide condensate, with the addition of acetic acid to improve exhaustion of the dyebath. Dyeing with disperse dyestuffs may be effected in the presence of a surface active agent.  In examples fibres made of compositions comprising polypropylene, calcium stearate, titanium dioxide and polycondensates of epichlorohydrin, piperazine and (1 and 2) bisphenol A and (3) hydroquinone are dyed with acid, metallised and disperse dyes.

Title: Process for the preparation of monotertiary butyl 4-methoxyphenol
Inventor: RODGERS GEORGE FARRIS
Filed: 1954-07-19
Abstract: A mixture of 2- and 3-tertiary butyl-4-methoxy phenols is prepared by reacting 2 : 5-ditertiary butyl-4-methoxyphenol with 4-methoxyphenol, in the presence of boron trifluoride, or an addition complex thereof with an alcohol ether or acid, as catalyst, and in an aromatic hydrocarbon solvent of the benzene series at a temperature of from about - 10 DEG  C. to about 110 DEG  C. The catalyst is present in amounts between about 0.5 and about 10 per cent, based on the weight of the reactants which are used in approximately equimolecular amounts.  The solvent may contain from 6 to 9 carbon atoms and benzene, toluene and xylenes are specified.  The amount of solvents used is advantageously between an equal amount by weight, to an amount double that of the reactants.  The compounds of the invention are food antioxidants, the 2-isomer being more potent.  The methyl ether, i.e. the dimethyl ether of monotertiary butyl-hydroquinone is used as an odorant.  In the example, a benzene solution of 2 : 5-ditertiary butyl-4-methoxyphenol and 4-methoxyphenol containing boron trifluoride, was reacted for 68 hours at room temperature.  The product was purified by distillation at reduced pressure, the ratio of the 2- to the 3-isomer in the final product being 0.36.

Abstract: 765,584. Glass-metal seals. FERRANTI, Ltd. July 18, 1955 [July 21, 1954], No. 21215/54. Class 36. A metal surface to which glass is to be sealed is formed with one or more channels 15 extending from an interior region to a boundary 17 of the surface, the channels being shaped and/or located so that during at least part of the sealing process, a decreasing temperature gradient is maintained in the glass overlying the channels from the region to the boundary. The channels may increase in width and depth towards the boundary. To seal glass across an aperture 11 in a metal diaphragm 12 the channels 15 are disposed as shown. The diaphragm is heated by an eddy current coil surrounding it, thus maintaining a decreasing temperature gradient between the outer and inner boundaries 16, 17 of the seal. Those parts of the glass overlying the channels are not initially in contact with the metal and are therefore subjected to a more rapidly decreasing temperature gradient.

Title: A stable, non-caking suspension of cortisone acetate in an isotonic aqueous vehicle and the process of preparing said composition
IPC: A61K31/573
Filed: 1951-09-12
Abstract: A stable, non-caking suspension of cortisone acetate in an aqueous vehicle is obtained by milling the cortisone acetate with the vehicle until stable crystals of reduced particle size are produced.  The crystals show the following X-ray diffraction data:-Interplanar spacing-15.5 A, 8.65, 5.94, 5.64, 5.01, 4.78, 4.41, 4.15, 4.09, 3.95, 3.82.  It is preferred that 90 per cent of the crystals have a size of 0 to 10 microns in length and none is greater than 50 microns. Preferably 5 to 15 parts of cortisone acetate are milled with 95 to 85 parts of aqueous vehicle using a hard glass mill e.g. 6 litre "Pyrex" (Registered Trade Mark) bacteria grinding jar and aseptic conditions.  The mill charged with the steroid compound, the vehicle, and glass beads is rotated at a rate of 25 to 45 revolutions per minute at a temperature of 20 DEG  C.  If desired, before milling, the mixture may be "seeded" with a suspension of the stable crystalline form of cortisone acetate.  Preferably the aqueous vehicle is rendered isotonic by e.g. the addition of sodium chloride, and also contains a suspending agent, a surface active agent and a preservative.  The suspending agent may be sodium carboxymethylcellulose, methyl cellulose, gelatin or sodium alginate; the preservative-benzyl alcohol or phenol; the surface active agent-sodium lauryl sulphate, cetyl trimethyl ammonium bromide, high alkyl (C8-C18) dimethyl benzyl ammonium chloride or polyoxyalkylene derivatives of sorbitol anhydride long chain fatty acid ester e.g. polyoxyalkylene derivatives of sorbitan monooleate.  In one example, isotoxnicity is produced by the addition of sodium citrate and N/10 hydrochloric acid.  Cortisone is 11-dehydro-17-hydroxy corticosterone.

[Also in Division G3] A method of modifying the electrical thickness of a specimen to conform to a desired pattern comprises determining whether the thickness exceeds the desired thickness, and then actuating machining means to reduce the thickness. A radome specimen 7 is located in a headstock 10, and a tailstock 6, carried by a table 1, the latter having wheels 2 which run along rails 3 on a bed 4. The headstock is rotated by a motor 11, through gearing 12, and a chain drive, and a lead screw 20 for moving the table along the rails, is rotated in a nut 22 by gears 17 and 19, driven by motor 11. A rotary cutting tool 37 driven by a motor 38 is carried by a pivoted arm 31, which projects through the headstock 10 and is adjusted relative to the work by a worm 40 actuated by a motor 41. A sensing head 42 forms part of a thickness measuring device 43, and in operation is brought into contact with the outer surface of the radome 7 at the point where the tool 37 makes contact with the inner surface of the radome. The table 1 is then moved to bring head 42 and tool 37 to the wider end of the radome. The work is rotated, and table 1 is moved along rails 3, thus scanning the radome in spiral manner, and the device 43 controls motor 41 to adjust the tool in accordance with the difference between the actual, and required thickness. In a modification, tool 37 is replaced by a reflector, the radome is scanned, and the information is recorded on e.g. punched cards, this information then being used to control the tool when the reflector is replaced by the latter. Specification 993,050 is referred to.
