Title: Resins containing 4-vinyl pyridine and a method of manufacture thereof
Inventor: GROSMANGIN J
IPC: C08F20/08
Filed: 1970-11-16
Abstract: 1298890 4-Vinyl pyridine-divinyl benzene copolymers COMPAGNIE FRANCAISE DE RAFFINAGE 16 Nov 1970 [15 Nov 1969] 54468/70 Heading C3P A copolymer of 30 to 70% 4-vinyl pyridine, 10 to 60% divinyl benzene and 0 to 40% of styrene is obtained by copolymerizing under an inert gas at 60‹ to 120‹ C. in a suitable monomer solvent within a specific range of monomer volume : monomer volume plus solvent volume (0À2 to 0À6). The copolymers may be used for removal of impurity metals from polymer solutions, the "accessibility" of the nitrogen atoms for such a reaction being a major feature of the copolymers. In examples the above copolymers are obtained in H 2 O- pyridine or heptane mixtures containing NaCl and polyvinyl alcohol and the products used for removing Ti, Al and Fe impurity metals from a polybutene solution in xylene.

Title: Process for the preparation of ª‡-amino acids
Filed: 1966-12-07
Abstract: a -Amino acids are prepared by the one-stage conversion of an aldehyde by means of ammonia and a cyanide into the corresponding a -aminonitrile and subsequent hydrolysis of the nitrile formed, the conversion to the a -aminonitrile being carried out in a reaction medium having dissolved therein at least one compound which enhances the solubility of ammonia in the reaction medium, the said compound being one or more of ammonium chloride, ammonium bromide, ammonium cyanide, sodium iodide, potassium iodide and lithium chloride, in a total proportion of more than 0.5 mole per mole of aldehyde to be converted and the reaction is carried out with at least the proportion of ammonia required to saturate such a reaction medium. The reaction medium is preferably kept saturated with ammonia.  The reaction is preferably carried out at temperatures in the range from 0 DEG  to 70 DEG  C., and the subsequent hydrolysis may be carried out by any known technique.  Examples are given of the preparation of methionine, alanine, and glutamic acid.

Abstract: 1452304 Thermo-magnetic switch TOHOKU METAL INDUSTRIES Ltd 30 Nov 1973 [30 Nov 1972] 55690/73 Heading H1N A curie point switch having a range of temperature at which the contacts are operated is arranged to be inoperative both above and below the temperature range and has a sealed magnetic reed contact unit whose reeds 12, 13 are influenced by two permanent magnets 2, 3 having curie points above the operative range and two ferromagnetic members 4, 5 having curie points at the lower and upper ends respectively of the temperature range. As shown in Figs 3A, 4A and 11A the flux distribution when the temperature is below the curie point of member 4 is such as to permit the contacts to remain open. When the temperature is above the curie point of member 4 but below that of 5 the magnet flux closes the contacts Figs. 3B, 4B, 11B (not shown), and when the temperature is above the curie point of the member 5 the flux does not pass through the contact points Figs. 3C, 4C, 11C, (not shown), and the contacts are permitted to open. The contacts may be arranged as in Fig. 12A which provides for contacts to be open between the two curie point temperatures and the magnets for arrangements such as that of Figs. 4A, 11A and 12A may be cylindrically disposed around the contact unit 1 with or without non- magnetic inserts, Fig. 14, (not shown) and a longitudinal grove Figs. 7A, 7B, 8A, 8B, and 15, (not shown), allowing contact connections to be made at one end of the switch.

Abstract: 1299610 Semi-conductor processing PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 30 Dec 1969 [31 Dec 1968] 63247/69 Heading H1K [Also in Division B1] In the formation on a monocrystalline substrate of a semi-conductor layer by liquid phase epitaxy the material for the liquid phase is melted and only then brought into contact with the substrate, contact being effected by the use of a slide forming part of the growth crucible. As shown in Fig. 1 the substrate 2 lies on the floor of the crucible and the melt 10 is formed above the slide 3 which is spaced slightly from the substrate. At the desired melt temperature the slide is pulled back to deposit the melt on the substrate. The entire solute may be crystallized or the slide (the upper side of the leading edge of which may be tapered) may be introduced at a particular lower temperature to separate off the bulk of the melt. As shown in Fig. 4 the substrate 27 is instead carried in a recess 28 in the slide 24, the slide being inserted when the desired melt temperature is reached. (It need not then be a consequence that the substrate is heated during fusing of the melt). The crucible shown has two compartments the melts of which may contain the same semiconductor with different impurity concentrations and/or impurities of different conductivity type or the two melts may contain different semi-conductors. The substrate may be placed successively or alternately in the two molts to grow two or more superimposed layers. The substrate may be semi-conductor or monocrystalline alumina. Boron nitride or quartz may be used for the crucible. A typical melt may be made by saturating gallium with arsenic or with gallium arsenide at 900� C. Deposition from the melt may be started at about this temperature and, for example, stopped when the melt temperature has fallen to 500� C.
