Filed: 1923-02-07
Abstract: 193,044. Hopkinson, E. Feb. 9, 1922, [Convention date]. Latex, treating; plastic compositions containing india-rubber &c. and oils &c., clay &c. - Compounding materials such as vulcanizing ingredients, oils, fillers, colouring-agents &c. are mixed with latex to which has been added an agent to prevent premature coagulation, and the mixture is agitated during coagulation to secure homogeneity. Ingredients capable of absorbing water from the latex may be wetted to prevent premature coagulation on mixing. An oil may also be added to the latex and the other ingredients. According to an example, 2 parts of glue are added to latex containing 100 parts of rubber to retard coagulation, and with this is mixed 10 parts of zinc oxide, 8 parts of sulphur, and 200 parts of clay, previously wetted if desired. The mixture is placed in a mixing machine and agitated during drying, until the mass is in a granular state. Drying is completed in the open and the mixing is vulcanized at 60 lbs. steam pressure in an hour. Specification 157,978 is referred to.

Title: A method for the production of 5-nucleotides
IPC: C12P19/30
Filed: 1963-01-30
Abstract: 51-Nucleotides are obtained by suspending grown asporogeneous yeast in an aqueous medium at a temperature of 20 to 50 DEG C. and having a salt concentration of 0.1 to 0.5 mole per litre until the ribonucleic acid of the yeast is degraded into 51-nucleotides which come out from the cells and accumulate in the aqueous medium, said medium having a pH of 3.0 to 6.0 for at least the first ten minutes of the suspension and recovering the accumulated 51-nucleotides from the aqueous medium. The asporogeneous yeasts to be used may belong to the genera Brettanomyces, Candida, Cryptococcus, Kloeckera, Mycoderma, Rhodotorula or Torulopsis and suitable species of each type are specified. The culture medium used to form the grown yeast generally contains an assimilable carbon source, a digestible nitrogen source and preferably inorganic substances, vitamins and other growth promoting factors and the incubation is usually carried out for 10 to 72 hours at 25 to 30 DEG C. The grown raw cells are then kept in the aqueous medium which is preferably an acidic buffer solution, e.g. an acetic acid or succinic acid buffer solution of pH 3.0 to 6.0 and the suspension is usually allowed to stand or is shaken or agitated for 1 to 10 hours. If desired, the grown yeast can be separated from the culture medium before keeping in the aqueous medium. The salt present in the aqueous medium may be organic or inorganic and is preferably sodium, potassium or ammonium chloride. When the grown yeast is subjected to the aqueous medium without being separated from the culture medium the latter is adjusted to a pH of 3.0 to 6.0 preferably 4.5 to 5.5 and a salt concentration of 0.1 to 0.5 mole per litre, e.g. by the addition of solutes or buffer solutions or by dilution with water. The pH of 3.0 to 6.0 is maintained for at least ten minutes and may then be allowed to rise, e.g. to pH 7. The asporogenous yeasts are preferably subjected to a physical or chemical treatment prior to or during the suspension process, e.g. by freezing or freezing and thawing repeatedly before suspending them in the aqueous medium or by contacting them (a) with an organic solvent such as ethyl acetate, toluene or acetone, (b) with an antibiotic e.g. nystatin, eurocidin, candimycin, amphotericin B or trichomycin, (c) with a cationic surface active agent such as cetyl trimethyl ammonium bromide or (d) with a glucanase produced by a microorganism belonging to the genus Trametes or Streptomyces. The 51-nucleotide product generally comprises 51-adenylic acid, 51-guanylic acid, 51-uridylic acid and 51-cytidylic acid.  If deaminase is present 51-inosinic acid and/or 51-xanthylic acid may also be obtained. In examples the yeasts used are Rhodotorula pallida Lodder and Mycoderma tannica Asai. Specifications 912,790 and 933,826 are referred to.

IPC: H01L21/00
Filed: 1965-01-29
Abstract: 1,022,159. Field effect transistors. STANDARD TELEPHONES & CABLES Ltd. Jan. 29, 1965, No. 4030/65. Heading H1K. A field effect transistor is provided in a semi-conductor layer epitaxially grown on a substrate of the same conductivity type by a process in which the surface of the substrate, before the epitaxial growth, and of the grown layer are doped with the opposite type impurity, this impurity being diffused into the epitaxial layer until the impurity-doped regions link up to form an isolating region surrounding the region containing the channel of the F.E.T. The substrate 1 (Fig. 1A, not shown), may be of P-type silicon with a localized N-type surface region 2 formed by diffusion of antimony or arsenic through an oxide mask. An epitaxially grown P-type silicon layer is then applied over this surface and its own free surface further doped with phosphorus, again by masked diffusion, to form local N-type regions 4 (Fig. 1C, not shown). Continued diffusion causes the regions 2 and 4 to join into a single N-type isolating region surrounding the P-region 5 of Fig. 1D. To the surface of this region are applied ohmic contacts 7, 8 (Fig. 1F, not shown) and a rectifying gate contact 6 between them. In the device of (Fig. 2 not shown), this gate comprises a diffusively doped region linking up with the isolating region, but it could be separate from the latter in which case the latter could function as a second gate. The isolated F.E.T. may form one element in a monolithic circuit block.

Abstract: 270,806. Frenchs, Ltd., Hawes, A. B., Horton, R. W., and Mayo, F. C. C. Feb. 12, 1926. Hasp fastenings.-Relates to the construction of the telescopic hasp fittings of two-part expanding suit and like cases. Figs. 3 and 4 show the construction of the hasp members, the outer casings 8 of which are rigidly secured to the outer portion 2 of the suit case, the sliding inner members 7 terminating in hinged hasp plates 5 adapted to engage locks 4 fitted to the inner portion 3 of the case. To prevent separation of the parts after the outer cover part 4 has been closed down to the appropriate depth over the filled case and the hasp engaged with the lock, a rod 10 is slidably disposed within a hole in the member 7. The inner end of the rod, which is urged towards the hasp by a spring 15, is recessed to form an inclined notch 12 engaging a roller 13 which lies partly in a transverse recess 14 in the part 7. With the hasp closed, any attempt to separate the parts 7 and 8 causes the roller to be jammed between the incline 12 and the inner surface of the part 8. The outer end of the rod 10 is, however, adapted to be engaged and moved inwardly by a projection 11 on the hasp when that part is raised; in this position the roller is prevented from jamming, and the hasp members can be moved relatively to each other in either direction. The carrying handle 20 is secured to lugs 17 on the members 8. In the modified construction of hasp member shown in Fig. 7, the rod 10 is normally inwardly spring-pressed so that the roller 13 is jammed between inclines 32 on the part 7 and the inside of the casing 8 and outward movement of the member 8 is prevented; the rod may be retracted against the action of the spring by means of a finger-piece 30 causing the roller to ride down inclines 32 on the part 7 into a position where free relative movement of the members in either direction can occur. To prevent complete separation of the members 7, 8 the latter has at the underside a longitudinal slot 40 in which a pin 41 on the underside of the member 7 engages.
