Title: A process for the production of xanthosine by fermentation
IPC: C12P19/30
Filed: 1963-07-05
Abstract: In a process for the production of xanthosine an artificially induced guanine and/or adenine requiring mutant of Bacillus subtilis, Escherichia coli, Bacillus megaterium or Rseudomonas perlurida is aerobically cultured on an aqueous culture medium comprising an assimilable carbon source, an assimilible nitrogen source and an organic growth promoting agent, at a temperature substantially between 25 DEG  and 37 DEG  C. and at a pH value of between 5.5 and 8.0 until xanthosine is accumulated in the medium.  The xanthosine is recovered from the broth by selective adsorption on ion exchange resin or on activated charcoal.

Title: Age-resisting rubber compounds and a process of making the same
IPC: C08K5/36
Filed: 1930-09-08
Abstract: The reaction product of an aminodiphenylmethane and a naphthol is condensed with sulphur to give an antioxidant for rubber.  The preferred reaction product is prepared by reacting one mol of p-p<1>-diaminodiphenylmethane and two mols. of b -naphthol together and condensing one mol. of the product with one gram atom of sulphur. In examples the reaction product of p-p<1>-diaminodiphenylmethane (1 mol.) and b -naphthol (2 mols.) is condensed with different quantities of sulphur in the presence of iodine as catalyst.ALSO:The age-resisting qualities of rubber are improved by incorporating in the uncured rubber mix a substance prepared by reacting an aminodiphenylmethane with a naphthol and reacting the product with sulphur to form a sulphur derivative.  The preferred reaction product is obtained by reacting 1 mol. of p.p1-diaminodiphenylmethane with 2 mols. of b -naphthol and 1 mol. of the resulting product with 1 gram atom of sulphur. Examples of the production of these bodies by the condensation of the reaction product of p.p1-diaminodiphenylmethane (1 mol.) and b -naphthol (2 mols.) with different quantities of sulphur in the presence of iodine as catalyst, and tables showing the antioxidant properties of these products, are given.

Title: Improvements to latex gels, particularly for the purpose of electrophoresis, and a new process of electrodeposition
IPC: C08C1/14
Filed: 1964-07-01
Abstract: Rubber latex for use in electrophoretic deposition to form articles, is pre-treated with a non-ionic colloid e.g. ethers of aromatic poly glycols, which coat the individual latex particles. A sensitizing agent e.g. methyl polyvinyl ether, is added before coagulating the latex electrophoretically.  It is stated that the pre-treatment with a non-ionic colloid neutralizes the effect of anionic stabilizers normally added to a latex, and is itself neutralized under the subsequent application of the electric field. Test apparatus are described showing complete coagulation of latex in a few secs. with 24 V applied.  The application of the latex in making a rubber impregnated textile tube sheath in a continuous operation, using an H.F. electric field, is also described.

Title: Improvements in and relating to thermionic amplifiers
IPC: H03F3/02
Filed: 1928-09-21
Abstract: 322,814. Green, H., and Celebritone, Ltd. Sept. 21, 1928. Thermionic amplifiers.-An inter-valve coupling comprises an inductance K, Fig. 1, in the anode circuit of the preceding valve V<1> coupled by a pair of condensers M<1>, M<2> of ample size to pass all low frequencies to a transformer L in the grid circuit of the succeeding valve V<2>. The resistance of the anode coil approximates to that of the valve V<1>, and the primary coil L<1> of the transformer, to which the terminals of the anode coil are coupled, has an inductance approximating to that of the anode coil. The anode coil and the transformer are constructed as sectional windings on an open core of very fine wires. The anode coil embodies resistance windings, when the valve V' is of high impedance, and at least the primary of the transformer is wound with very fine wire of high conductivity to minimize weight and bulk. To handle the outputs from two parallel valves V<3>, V<4>, Fig. 2, having theirgrids fed from separate inputs, for example the regulated inputs from a pair of gramophone pickups, a single centre-tapped coil K<1> provides anode coils for the two valves, the resistance of each half matches the resistance of the corresponding valve, and the inductance of the primary of the transformer, which is coupled by condensers M<1>, M<4> to end terminals of the anode coil, matches the inductance of each half of the coil. To prevent back coupling between successive stages a resistance R is inserted in the plate supply lead of the valves V<3>, V' to bye-pass pulsating-currents through a condenser M<3>.

Abstract: 683,476. Making machinery frames. WILKINS & MITCHELL, Ltd., and HOLBERRY, E. G. Sept. 27, 1950 [Oct. 26, 1949], No. 27450/49. Class 83 (ii). [Also in Group XXIX] Relates to a power press of the type in which the press frame is a box structure made from steel plates welded together at the four corners of the frame, components such as the hydraulic power ram or slide and the cushion ram being slidably mounted in guide members which must be accurately located in the press frame. According to the invention, inserts having machined contact surfaces on their innermost faces are passed through holes in the press frame and into correct locating engagement with machined contact faces of an accurately positioned guide member, and the inserts are then fixed to the frame walls in correct locating positions, preferably be welding. Fig. 1 (plan view) shows a press frame 1 enclosing a column 2, being one of a pair to which guides for the ram are secured. Inserts 3 are passed through holes 4 in the frame and are welded into position at 5. The bush-like inserts have accurately machined end-faces normal to the bush axis, and they engage accurately-machined contact surfaces 2x on the column 2. The column is secured to the bushes by screwed studs 6. Each hole 4 may be reamered to afford a slight clearance around its insert to allow the latter to be adjusted before welding. Fig. 3 shows a guide 11 on which the press slide 8 runs, the guide being located by modified inserts each having an annular rib 3x which affords a fulcrum about which the insert may be rocked into position prior to welding. Bolts 9 secure the guide to the bushes and slots 12 in the guide allow of adjustment for wear by means of set-screw 13. In a modification of the Fig. 1 arrangement, Fig. 2 (not shown), the plain inserts and studs of Fig. 1 are replaced by the ribbed inserts and bolts of Fig. 3. In a modification of the Fig. 3 arrangement, Fig. 4 (not shown), the adjustment slots 12 are provided in the inserts instead of in the guide. Fig. 5 shows inserts having such adjustment slots 12, these inserts being barrel-shaped so that they may be rocked for positioning purposes. A guide-plate for the bottom or cushioning ram of the press may be located in a manner similar to that shown in Figs. 1 and 3, i.e. with studs and ribbed inserts, Fig. 6 (not shown).

Reduction in the complexity of the horizontal computers HRW is possible due to the assertion that, for a system using digital phase devices P, Fig. 2, having q bits, the vertical and horizontal computers VRW and HRW, calculating binary numbers to represent the horizontal and vertical values to be applied to the element stores ESP to p places, where p is chosen to accord to the desired phase accuracy, and p>q, the last p - (q + 1) digits for each word in the HRW computers are found to be the same for each row. These common digits may therefore be calculated separately in a common computer, the carry line of which is fed to each individual HRW which calculates the higher digits for each word corresponding to its respective row. In Fig. 2 a 10 bit system may have the last 5 bits calculated commonly in horizontal computer HRW1 and fed along with the carry bit the various in situ horizontal computers HRW. It is stated that the cost involved with horizontal computers is halved by such an arrangement. Operation of the system is disclosed by reference to an exemplary computation.
