Abstract: 1,247,361. Phenyl-hydrocarbyl-pyridines. IMPERIAL CHEMICAL INDUSTRIES Ltd. 5 May, 1969 [6 Feb., 1968], No. 5907/68. Addition to 1,098,725. Heading C2C. Phenyl-hydrocarbyl-pyridines where the hydrocarbyl substituent is methyl, ethyl or vinyl, are obtained by heating a phenyl-substituted amine or imine with iodine in the vapour phase at 300‹-800‹, the amine or imine comprising a nitrogen atom and six acyclic carbon atoms (for the production of phenyl-methyl pyridines) or seven acyclic carbon atoms (for the production of phenyl-ethyl or vinyl-pyridines) contained in one or two N-hydrocarbyl groups, and additionally comprising a third N-hydrocarbyl group in tertiary amines, one of said carbon atoms, other than a tertiary carbon atom, bearing the phenyl substituent, the whole bearing sufficient hydrogen atoms to permit cyclization to the required pyridine with loss of hydrogen and, in the case of a tertiary amine, of said third hydrocarbyl group. Preferred starting materials have the formula in which R is methyl or ethyl, X is hydrogen or a substituent inert under the reaction conditions, e.g. halogen, and Y is hydrogen or hydrocarbyl or is absent in the case of an imine. When R is ethyl dehydrogenation may occur to give a vinyl product which, if required, can be hydrogenated. The cyclization may be effected over a bed of an inorganic oxide which is inert to the HI by-product, e.g. silica or alumina, or a metal oxide which takes up the HI, e.g., calcium oxide. Iodine may be generated in situ from metal iodides and oxygen. Examples describe the preparation of 2 - phenyl - 5 - methylpyridine, 2 - (p - chlorophenyl) - 5 - methylpyridine and 2 - (p - chlorophenyl) - 5 - vinylpyridine which may be hydrogenated to obtain the ethyl compound. N - (Isobutylidene) - 1 - phenylethylamine is obtained by condensing isobutyraldehyde and 1 - phenylethylamine. N - [1 - (p - chlorophenyl) ethylidene] - isobutylamine and N- [1 - (p - chlorophenyl) ethylidene] - 2 - methylbutylamine are prepared by analogous methods.

Title: Improvements in or relating to epitaxial deposition of silicon
Inventor: ROE CHARLES CLIFFORD
IPC: H01L21/205
Filed: 1963-02-14
Abstract: Si is deposited epitaxially on a monocrystalline Si substrate by heating the substrate in SiCl4 or SiHCl3 at a temperature above the minimum necessary to deposit monocrystalline Si, until a layer of Si has formed, and then reducing the temperature for the remainder of the deposition.  The respective temperatures may be 1100-1300 DEG  C. and above 900 DEG  C., e.g. 950 DEG  C. for SiCl4, and 1000-1300 DEG C. and above 800 DEG  C., e.g. 850 DEG  C. for SiHCl3.  The substrate may be heated by resistance, r.f., or radiant heating.  In the example, a polished Si slice was placed on a quartz plate on a graphite heating strip in a quartz reaction tube.  First argon, then H2 was passed through, and the slice heated to 1000 DEG  C.  After 13 mins., part of the H2 was bubbled through liquid SiCl4 and mixed with the main H2 feed; the temperature of the slice was raised to 1200 DEG C. and the reactant gases passed into the tube.  After 1 min., the temperature was reduced to 950 DEG  C., and deposition continued for 15 mins.  The supply of SiCl4 was then stopped, and the tube was allowed to cool in H2 flow and finally purged with argon.  A flow system is described diagrammatically, and flow rates given.  A p-n junction may be obtained by adding a doping impurity to the H2 or Si compound feed, and depositing on to a previously doped substrate.

Abstract: 563,157. Typewriters ; manifold record strips. WILLIAMS, W. P. (Standard Register Co.). April 20, 1943, No. 6329. [Class 100 (iv)] [Also in Group XV] Apparatus for automatically separating manifold record strips and interleaved carbon or other transfer strips from a zig-zag pack of stationery that has been typed or written upon to form individual packets, is constructed with means for giving the assembled strips a vibratory or jogging action to facilitate their separation. The invention is described in connection with an apparatus in which a pack 7 of printed strips is supported on a platform 8 carried by a frame 1 formed of connected girders in which is mounted a number of inclined shelves 2 constructed so as to facilitate the re-folding of the record strips which are separated from the pack and are directed by shoots 4 into the receiving compartments 3, the shoots being formed with bulges 3a to facilitate the reformation of the zig-zag folds. The carbon strips are directed . by shoots 5, 5a and pass on to a driven belt 10 which feeds them into a receptacle 9. Alternatively, if these strips are to be used again they may be re-folded and stored in receptacles similar to and arranged under the receptacles 3. A receptacle 6 may serve to receive an additional strip if the pack contains more strips than receptacles 3, or this receptacle may be used to store a full pack which is led from the receptacle either to a typewriter and thence to a separating-device, or directly to the separating device. The composite strip may be forwarded for separation by means of frictional feed rollers, the driven one of which is on a shaft 16, or the shaft 16 may be fitted with one or more pin-feed wheels 23, Fig. 8, to engage feed apertures in the strips, the wheels being splined to shaft 16 and being adjustable axially so as to register with the apertures. A guide 39 is associated with the pin-wheels, and the shaft 16 is driven intermittently by Geneva gear as shown in Fig. 4, so as to cause a tendency of the strips to separate owing to the vibratory nature of the feed. The Geneva gear comprises a gear driven by a motor 12 and having a segmental gear 20 which engages alternately with gears 15 on the shaft 16, the gears 15 being separated by concave parts which engage the plain part 21 of the driving-shaft during the time that the shaft 16 is stationary. The separation of the strips may be assisted by an oscillating plate 43, Fig. 8, carried by a spring- controlled lever 40 operated by pins 42 on the feeding-wheel 23.
