Title: Thermal polymerisation of olefinic nitriles
Inventor: KERN ROLAND JAMES
IPC: C08F20/44
Filed: 1956-11-08
Abstract: Acrylonitrile and/or methacrylonitrile are polymerized by heating the monomer or mixture of monomers, e.g. to a temperature between 75 DEG and 125 DEG  C., in the presence of a small but catalytic amount, e.g. 0.01 to 0.1% by weight on the monomer, of a thiuram disulphide as the sole polymerization catalyst having the general formula <PICT:0823273/IV (a)/1> in which each of R, R1, R2 and R3 is an alkyl group having up to six carbon atoms, which may be substituted by a non-functional substituent, or R and R1 and/or R2 and R3 together form a pentamethylene group which may be substituted by a non-functional substituent, for example tetramethyl-, tetraethyl, tetraisopropyl-, N,N1-dipentamethylene-, tetra-(beta-chloroethyl)- and sym.-dibenzyldimethylthiuram disulphides.  Polymerization may be carried out in bulk, in solution in solvents such as benzene, toluene, ethanol and acetone, in suspension in water containing a suspending agent such as starch, carboxymethylcellulose, a phosphate or a vinyl acetate/maleic anhydride copolymer or in aqueous emulsion containing emulsifiers such as sodium and potassium fatty acid soaps, sodium alkaryl sulphonates and the condensation products of ethylene oxide with tertiary alkyl mercaptans.

Title: Improvements in and relating to the production of protective coatings on iron and steel articles
IPC: C23C22/46
Filed: 1932-12-06
Abstract: An oxalate coating is produced on iron or steel articles by treatment with an aqueous solution of oxalic acid, the action being accelerated either chemically by the addition of sulphuric acid, a ferric salt, or a mixture of sulphuric acid and a ferric salt, or electrically by making the article the anode in an electrolyte of oxalic acid with or without either or both of the chemical accelerating-agents referred to.  The ferric salt may be for example ferric sulphate, ferric oxalate, or potassium ferrioxalate, and a colouring agent, e.g. potassium ferricyanide, may be added to the solution.  The coating may be deposited anodically with an insoluble cathode such as a carbon rod, a potential of from 0,5-2 volts and a current density of from ,005-,05 amperes being employed.  The coating may be oiled, painted, enamelled, or lacquered and the process may be used for providing an electrically insulating layer on iron or steel stampings for armatures, field coil cores, or transformer cores.

Abstract: 1404663 Rolling mills TIMKEN CO 25 July 1972 [4 Nov 1971] 34784/72 Heading B3M A strip rolling mill incorporates a fluid circulating system associated with the roll necks of backing rolls 13 and 14 or work rolls 11 and 12 the system controlling the temperature and shape of these rolls in order to produce a flat strip from the mill. In one form, (which may be water) fluid is forced by a pump 31 (Fig. 2) through conduits 26 to the backing roll necks (Fig. 3), the fluid returning via conduits 25 to return lines 34. The flow of fluid is controlled by valves 38 in response to the temperatures adjacent the roll necks, as measured by thermocouples 39. The fluid is so controlled that a desired heat balance is maintained in the roll necks, the fluid either removing or adding heat. A fluid circulation system is also applied to the chocks of the backing rolls. The fluid flow control valves for this system may be manually or automatically controlled.

Abstract: 1402776 Safety belt buckles S M LINDBLAD 26 July 1972 [3 Aug 1971] 34999/72 Heading E2A A safety-belt buckle comprises complementary interengageable buckle parts adapted to be fastened together and one of the parts comprises a casing 1 which houses electrical, switch means having contacts relatively slidable one over the other into and out of mutual engagement, the sliding of the contacts and switching state of the switch means being determined as a function of engagement or disengagement of the two buckle parts. As shown, a spring-loaded detent 15 is engageable in a slot in a tongue 25 insertable between guides 13, 14 in the casing 1, an operating plate 22 being tiltable to displace the detent for release of the buckle parts. The switch means is connected in the circuit of a signalling device used in conjunction with a switch associated on ignition lock and a switch actuated by a seat whereby when these latter switches are closed and the belt is not in use a signal is emitted; an additional circuit in parallel with the buckle switch incorporates a solenoid device for releasing or securing a belt take-up reel. Insertion of the tongue 25 into the casing 1 breaks contact between a conductor 46 and a spring-loaded sleeve 45 which acts as a tongue ejector. In a modification, there is a spring blade contact which, when the tongue is inserted further into the casing than is normally required to fasten the buckle, closes a circuit through a solenoid to release the belt take-up reel.

Abstract: 1514830 Liquefaction of coal LUMMUS CO 22 Aug 1975 [26 Aug 1974] 35026/75 Heading C5E Coal is treated with a solvent to produce a solution which, after the separation of insoluble material, is separated into a net product and a solvent which is used to treat fresh coal, the solvent comprises a 600‹F+ fraction having at least 70 volume percent thereof boiling from 600‹F to 900‹F and at least 5 volume percent boiling above 900‹F. The liquefaction can be carried out at 700-1000‹F and up to 10,000 psia in the presence or absence of added hydrogen and/or catalyst such as cobalt molybdate, tungsten nickel sulphide or nickel molybdate on alumina or silica. Coal 10 is mixed with solvent 12 and treated in zone 14 and components boiling upto 600‹F are separated from the coal liquefaction product in zone 16. The separation of insoluble materials from a coal solution by gravity separation in zone 23 is improved by the addition of a liquid promoter 21 having a 5 volume per cent distillation temperature of at least 250‹F and a 95 volume per cent distillation temperature of at least 350‹F and no greater than 750‹F. The overflow 24 from separation zone 23 is flashed at 41 to recover a promoter liquid stream 42 and a residue 44 of which a portion 47 is used for preparing the liquefaction solvent 12 and the remainder is separated at 45 into a 900‹F + bottoms 50 and a 600-900‹F fraction 48 of which at least a portion 51 is used for preparing the liquefaction solvent 12. The underflow 31 is separated at 32 into a promoter liquid stream 43, a 600-900‹F fraction 33 and a bottoms 34 which can be calcined, coked or used to produce hydrogen for use in zone 14. Fig. 2 (not shown) illustrates a process in which the flashing column 41 is omitted and the overflow stream 24 is passed directly to a column from which the promoter liquid is recovered as an overhead, the 600-900‹F fraction required for producing the liquefaction solvent is recovered as a sidestream and a bottoms 600‹F+ fraction from which a net product stream 101 and a stream 102 which is incorporated in the liquefaction solvent is also recovered.

Abstract: 1,056,108. Dividing engines. J. HEIDENHAIN, [trading as WENCZLER & HEIDENHAIN]. Sept. 5, 1963 [Sept. 5, 1962], No.35208/63. Heading G1X. Relates to a precision instrument e. g. a dividing engine or measuring machine, comprising a table 2 (Fig.1) to which is secured a workpiece 1 e.g. a measuring scale, supported for movement on a carrier path 7 (Figs. 1, 2) by means of two spring-loaded levers 3, 4 pivotally connected to the table and having rollers 5, 6. The carrier path 7 rests on tubular supports 11 which extend through openings in a carrier member 13 without touching it and are attached to a support member 14 resting on a three point support on a base 16. The exact level of the table 2 is determined by guide paths 17, 18 underneath two rails 19, 20, on the carrier 13, and spring-loaded levers 22 pivotally connected to the table carry rollers 23 which engage the upper surfaces 24, 25 of the rails and thus urge the table toward the guide paths. In this way no bending force is exerted on the guide paths due to the table weight or due to deformation of the support member 14. A bridge 28 is carried and guided similarly to table 2 and may carry e.g. a photo-electric measuring microscope 29 for reading the scale 1 or a ruling mechanism for drawing lines. The weight of the bridge may act through hydraulic supports 34 on carrier paths 32, 33 and the bridge is guided by rails 30, 31.
