Title: Improvements in or relating to the production of synthetic resins
IPC: C08F214/06
Filed: 1943-07-26
Abstract: Vinyl and/or vinylidene halides or mixtures thereof are polymerised by heat, light or a catalytic per-compound (in any combination) in the presence of from 0.1-25.0 per cent of an oxide of styrene, of indene or of one of their nuclear-substituted derivatives.  The process may be carried out in bulk, in the presence of an inert diluent, e.g. methanol, or in aqueous emulsion.  Examples describe the preparation of copolymers of vinyl chloride and (1) styrene oxide; (2) indene oxide and (3) para-methyl styrene oxide.  The copolymers give products having increased heat-stability and reduced brittleness in the unplasticized condition.  Specification 572,767 is referred to.

Title: Improvements in or relating to means for supplying chip-removing fluids to drilling and like tools
IPC: F16L27/087
Filed: 1954-04-27
Abstract: 756,240. Drilling-machines; lubricating and cooling cutting-tools. FOSTER WHEELER, Ltd. April 27, 1954 [April 27, 1953], No. 12187/54. Class 83 (3). Cutting apparatus having an axially-movable and rotatable member carrying a cutting-tool fed with cutting-fluid through an internal passage includes a cylinder containing cutting-fluid under pressure carried by the member and communicating with the passage so as to provide fluid during rotation of the tool, the cylinder being axially movable with the tool, but being held against rotation therewith. A drill 21, of the type used in drilling gun-barrels, is provided, with a longitudinal passage 23, Fig. 2, extending from the cutting-point to a position approximately mid-way along the shank where it joins a transverse passage 24. The tool also has an external groove 27. The spindle 16 of a radial drilling machine carries an adaptor 20 into which the tapered shank of the drill fits. A cylindrical housing 29 surrounds the adaptor and has fluid sealing-devices at each end. Rotation of the cylinder is prevented by a key 54 which engages a vertical channel 52 in a casing 51, 68 carried by the drill-head. Pressure-fluid, which may be liquid or gaseous, is supplied by a pump 31, Fig. 1, through the pipe 30 to cylinder 29, from whence it passes through holes 25, Fig. 2, in the adaptor to the passage in the drill. A combined guide-bush 59 and seal, adjustable for height by a nut 63, is provided at the lower end of the casing 51, the end of the bush sealing the drill within the work. The pressure-fluid thus passes into the hole made by the drill and escapes with the cuttings up the groove 27.

Patent GB-620679-A (GB)
Title: Tanning agents and method for preparing same
IPC: C14C3/20
Filed: 1946-04-23
Abstract: Tanning agents are prepared by the sulphonation in vacuo of a phenol-formaldehyde-type resin with an amount of acid less than that required for the complete sulphonation of the phenol &c. in the resin, but sufficient to ensure that the resin is rendered completely soluble in water, the pH of the product being then brought to 3-4, e.g. by complete neutralization with ammonia or p  soda, followed by the addition of an organic acid.  Urea may be added to the resin in its preparation.  Sulphonation may be effected below 100 DEG  C., e.g. at 70-75 DEG  C.  Examples relate to the preparation of phenol-and cresol-formaldehyde resins.

Abstract: 1,155,542. Anhydrides. MONSANTO CHEMICALS Ltd. 20 Feb., 1968 [16 March, 1967], No. 12466/67. Heading C2C. Novel mixtures of aromatic polyanhydrides wherein the individual anhydrides can be represented by the formula PaBb, where P represents a radical derived by the loss of one or more hydrogen atoms from the nucleus of the phthalic anhydride molecule. B represents a radical derived by the loss of two or more hydrogen atoms from the benzene molecule and a and b are integers, are prepared by a process comprising the gradual addition of a benzene disulphonyl halide, preferably benzene metadisulphonyl chloride, to phthalic anhydride, using at least 1À5 and preferably 2 to 20 moles of anhydride per mole of benzene disulphonyl halide, under conditions such that SO 2  and a hydrogen halide are evolved and at temperatures preferably in the range 200-350‹ C., but possibly as high as 400‹ C., and removing any unchanged phthalic anhydride from the reaction mixture. The process may be performed in the presence of a catalytic amount of copper or a compound containing copper. The overall ratio of P: B units is generally 1: 2 to 2: 1 or preferably 1:1 to 2:1.

Title: Improvements in telephone systems comprising automatic telephone exchanges of different systems
IPC: B24B3/24
Filed: 1928-04-28
Abstract: 289,782. Telefonaktiebolaget L. M. Ericsson. April 30, 1927, [Convention date]. Automatic exchange systems.-A register-controller in a non-decimal exchange, when set for a call to a decimal exchange, modifies its circuits to eliminate translation. The non-decimal exchange has a capacity of 30000 (first digit 1, 2 or 3) and is equipped with selectors having 25 groups of 20 outlets operating on the revertivecontrol principle. The decimal exchange has a capacity of 20000 (first digit 4 or 5), is of the forward impulse type, and is reached over junctions such as CL occupying 20 groups of outlets in the first selectors GV1. Each outgoing junction has a group of relays FR - - LR by which the hundreds, tens and units digits are sent forward as interruptions of the loop 11 and at the same time sent back revertively to the registercontroller. The register-controller comprises subscriber-controlled registers RE1 - - RE5 and revertively-controlled registers RE6 - - RE9 which are interconnected to effect the translation demanded by the local 500-point selectors, but if the first digit dialled is 4 or 5 a relay UR is energized which shifts the control circuits 18, 20, 21 corresponding to the 2nd, 3rd and 4th selective operations to eliminate translation. The registers are of the type that take half a step when the magnet is energized and half a step on its release. Assuming that the call is 45678, the selector GV1 sets itself under joint control of the registers RE1, RE2, sending back revertive impulses from IS to DR and thence to RL6 until a circuit 8 is closed for relay ER, which energizes SOR2 to move the switch AK, BK half a step, whereby the circuit of ER is broken so that the switch completes its step. The selector then hunts for an idle junction CL, whereupon relay FR is energized, closing the loop 11. Relay KR is energized over 12 and closes a circuit 13 for GR, which alternately energizes and is shortcircuited by HR. At each short-circuiting of GR, IR is energized and opens the loop 11 and an impulse is sent back over 16 to DR. and thence to RE7, until ER is energized over 18 in accordance with the untranslated setting of RE3. Impulsing is stopped by the opening of circuits 12, 13, the switch SOR2 is moved to 3rd position, and circuit 12 is re-established. An inter-digit pause is provided by a sluggish relay LR, which is energized by the momentary release of ER and retards the re-establishment of circuit 13. Impulsing then starts again for the next digit, under control of circuits 20 and register RE4, and so on. Specifications 201,713 and 263,596 are referred to

Abstract: 528,747. Electric control and signalling systems. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. May 2, 1939, No. 13057. Convention date, Aug. 3, 1938. Drawings to Specification. [Class 40 (i)] In a centralized control and supervision system for apparatus located at a plurality of remote points and particularly for railway signals and points at different stations along a track, control and supervision are effected over a single line circuit by time-coded impulses generated by relays. Means are provided for storing codes for subsequent transmission as long as the line wire is in use and for maintaining an established direction of transmission to or from the central office as long as there are codes stored for transmission in that direction, the stored codes being transmitted in a group in a given order of code superiority. Transmission of any code which becomes stored after the transmission of a group of codes has been initiated is prevented until all codes of the group have been delivered. Normally the line wire is energized by positive current, but code sending from any station is effected by long and short impulses of reverse polarity. The operation of the system is similar to that of the system described in Specification 528,745, except that for effecting a station selection and the control of apparatus thereat chains of relays at the station are firstly operated until a particular station is selected and then the chain at the selected station is released and reoperated to effect the desired operations.
