Title: Processes for the production of steroid compounds
IPC: C07J7/00
Filed: 1960-01-22
Abstract: The invention comprises 11a ,17a -dihydroxy-16a -methyl-pregna-3,20-dione, the 3,20-diketals thereof, and a process for the preparation of compounds of the formula: <FORM:0934703/IV(a)/1> wherein R is =H(a -OH) or = O, which comprises condensing pregn-16-en-3,11,20-trione with diazo-methane in an inert organic solvent to form the corresponding 16,17-pyrazoline, subjecting this compound to thermolysis to form 16-methyl-pregn-16-en-3,11,20-trione, protecting the 3- and 20-keto groups of this compound, epoxidising the resultant product to form the corresponding 16a ,17a -epoxy-16b -methyl-pregna-3, 11,20-trione derivative wherein the 3 and 20 groups are protected, reacting this derivative with an alkali metal or an alkaline earth metal in the presence of a lower aliphatic amine to break the epoxide bridge, invert the steric position of the 16-methyl group and reduce the 11-ketone function, thereby obtaining the 11a ,17a -dihydroxy-16a -methyl-pregna-3,20-dione derivative wherein the 3- and 20- groups are protected and thereafter reliberating the protected keto groups to yield the desired compound in which R is =H(a -OH) followed, if desired, by oxidation of the latter to give the desired compound in which R is =O. Thermolysis of the 16,17-pyrazoline is effected by heating in a high b.p. solvent. The breaking of the epoxide bridge may be effected with lithium in the presence of monomethylamine at 0 DEG C. to -40 DEG C. Specifications 807,203, 874,779, 934,701 and 934,712 are referred to.

IPC: B01D39/14
Filed: 1960-09-30
Abstract: A cigarette filter plug formed from fibrous material has at least a third of its individual fibres laid transversely of the plug.

Title: Omicron, omicron-dimethyl-omicron-(4-cyanophenyl) thionophosphate and insecticidal compositions and methods using same
IPC: C07F9/18
Filed: 1961-07-14
Abstract: The invention comprises O,O-dimethyl-O-(4-cyanophenyl) thionophosphate. It may be obtained by reacting O,O-dimethyl chlorothionophosphate with 4-cyanophenyl or an alkali metal salt thereof. The reaction is preferably carried out in an inert organic solvent and substantially equimolecular proportions of the reactants are general employed. When the free 4-cyanophenyl is used the reaction is preferably carried out in the presence of an acid binding agent, e.g. an organic base such as pyridine or diethylamine, or an alkali metal carbonate or bicarbonate. Suitable solvents are hydrocarbons, halogenated hydrocarbons, alcohols, ketones and ethers. A dehydrohalogenation catalyst, e.g. copper powder or a cuprous salt may also be present. The product has insecticidal properties (see Division A5).ALSO:An insecticidal composition comprises an inert carrier and as active ingredient O,O-dimethyl O - (4 - cyanophenyl) thionophosphate (see Division C2). The invention also includes a method of eradicating injurious insects, especially borers of rice, from a crop area containing a growing crop which comprises applying to the crop area an insecticide comprising O,O-dimethyl O-(4-cyanophenyl) thionophosphate. The insecticidal compositions may be in the form of an emulsion, suspension, dust or oil preparation. In preparing the emulsion the active ingredient, which is stated to have low toxicity to warm blooded animals, may be mixed with an organic solvent, e.g. benzene or xylene, and a non-ionic surface active agent to form an emulsifiable concentrate suitable for dilution with water before use. Wettable powders may be obtained by mixing the active ingredient with a non-ionic surface active agent and a powdered carrier and are then added to water to form a suspension. Dusts may be formed by mixing the active ingredient with a powdered carrier with or without the use of a volatile solvent, e.g. acetone. Oil preparations may be obtained by dissolving the active ingredient in a solvent such as deodorized kerosene if desired with the use of a co-solvent, e.g. an aromatic hydrocarbon such as benzene, xylene or methylnaphthalene. A fungicide, herbicide or other insecticide may also be present.

Title: P-nu junction transistor with increased resistance in current path across base surface
IPC: H01L21/288
Filed: 1962-08-25
Abstract: Part of the base zone of a PNP transistor sandwiched between the P zones is removed, e.g. by electrolytic etching, to leave a marginal region in direct contact with only one of the P zones, so that the surface path between the P zones over this region exceeds the thickness of the base zone. In one embodiment a melt grown transistor with its contacts masked with wax is electrolytically etched in caustic potash with the emitter junction reverse biased (Fig. 3, not shown) until the edges of the base zone are removed back to the depletion layer (Fig. 4, not shown). In a second embodiment an alloydiffused transistor is formed by alloying emitter and base pellets 25, 26 (Fig. 13) of lead, antimony and aluminium and lead antimony respectively to a gold-doped P-type germanium wafer 23. An N-type layer 24 formed over the entire wafer surface in the process is then removed from the back face and a collector contact attached with indium-gallium solder. The assembly is etched as described above to the form shown. Alternatively the source of etching voltage may also be used to reverse bias the junction (see Fig. 12, not shown).

Title: Method of making a casting mold
IPC: B22C9/04
Filed: 1964-09-09
Abstract: A moulding process comprises coating a pattern with a layer of a fine-grained refractory and a binder, applying a layer of coarse-grained refractory thereto while still wet, allowing the layers to dry, then wetting the dry coated pattern with a binder and arranging it in a mould box and packing with a granular refractory and allowing said second binder to solidify, then removing the pattern. The pattern may be coated with a release agent such as petroleum jelly or silicone grease. The first coating layer may be zirconium silicate, aluminium oxide or aluminium silicate, with a silicic acid sol as binder, applied as an ethanolic suspension and hardened by the action of ammonia, by spraying with e.g. an aqueous solution of ammonium acetate, or by heating. The coarse-grained refractory may be aluminium silicate. The second binder may be a silicic acid sol, albumins, sodium silicate solutions and methyl cellulose, and the back-up material may be moulding sand. A surface-active substance such as sodium dodecyl naphthyl sulphonate may be added to the binder to promote wetting of part of the backing material thereby. Solidification of the second binder may be initiated by adding a coagulating substance to the back-up refractory or to the binder.
