Patent GB-710203-A (GB)
Title: Automatic communication system including directly-controlled and register-controlledco-operating exchanges
Inventor: OBERMAN ROELOF MAARTEN MARIE
IPC: H04Q3/00
Filed: 1952-02-11
Abstract: 710,203. Automatic exchange systems. STAATSBEDRIJF DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Feb, 11, 1952 [Feb. 19, 1951], No. 3617/52. Class 40 (4) A calling incoming circuit EER1 first causes an associated group selector EESS to hunt for a free register which then operates an associated finder F to search for the incoming circuits. During the hunting of F incoming digits are received by the register over selector EESS and subsequently they are received over F the group selector EESS then being freed for setting in the wanted direction EER2 under control of the register. The invention is intended for use in register .- controlled exchanges which receive calls from directly controlled exchanges so that rapid connection to a register-controller is essential. On receipt of an incoming call relay U operates and energizes the drive magnet DMEESS of the selector. When a free register is found test relay T in the selector. operates in series with relay R in the register. Relay R disconnects resistance W, from the circuit to busy it and brings up AA. Relay T stops the selector and operates P which connects the a and b wires over EESS to the digit receiver IR in the register. Relay R energizes the drive magnet DMF of the finder F. The register connects a characteristic potential determined by the potentiometer W2, W3 over the e wiper of EESS to the e-bank contact of F and this potential is also connected over the sequence switch SSB (position 1) by the potentiometer W4, W5 to the voltage-comparison device NW. When this potential is encountered by the e-wiper of F the device NW operates TT to stop the switch. TT also connects up a d.c. testing device GR which if successful operates GT. The latter brings up BB in series with AA. Relay BB connects the digit receiving device IR to the incoming a and b wires over wipers h, g of F. and releases TT. Relay GT follows and steps sequence switch SSB to position 2. Relay GT also brings up relay A in the selector. Relay A releases P which disconnects the incoming wires from the selector. Relay A also releases T. From the digits received by IR switches MS, ... MS4 are set, and bank MS1 connects potential from potentiometer W7, W8 to the device NW indicative of the wanted outgoing direction. When TT releases the selector drive magnet circuit is again made and the selector hunts for a free outlet having the required characteristic potential as determined by the potentiometer W8, W9. When such an outlet is found the potential comparing device NW operates TT to stop the switch, and GT operates to the d.c. test thereby bringing relay B up in series with A in the selector. Relay P then operates to switch through the incoming circuit via the selector to the outgoing trunk EESS.

[Classes 83 (ii) and 83 (iv)] Uniting by fusion.-Metal articles such as plates, structural iron, e.g. flats, rounds, angles, channel, rail, I, T, or Z sections, cylindrical pressure vessels, pipe elbows, &c., wholly or partially coated with a layer of metal of different composition, e.g. corrosion resisting metal such as chromium iron or chromiumnickel-iron, are made by depositing the coating on the base by maintaining an electric arc between a fusible electrode and the base with the end of the electrode kept beneath a blanket of flux and then deforming the coated base to form the article, e.g. by rolling, forging, extrusion, &c. The coating may be applied to one or more parts of the same surface or the same or different coatings may be applied to a number of surfaces. The coatings may be of different thicknesses. Coating is effected by the process described in Specification 475,709. A billet or slab 13 may have a coating 14 arc welded thereon, the composite billet being rolled in stages to produce a thinner plate 13<1> with a thin coating 14<1>. The original coating is usually about # to ¢" thick. An article with a coating on both sides of different thicknesses may be produced by coating one side, and after partially rolling the slab applying a coating of the original thickness to the other side and then completing the rolling. In making cylindrical pressure vessels from pierced billets rolled out to form seamless cylindrical rings assembled to form the vessel, the coating may be deposited on the external or internal surface of the ring or both at an intermediate stage of the operations. The billet may be coated before or after piercing or the ring may be partly rolled to size before coating and final rolling. The external coating may be of a metal resistant to corrosion by weather or fumes and the inside coating of a metal resistant to the contents of the container. A rectangular or polygonal billet may be coated on all its sides and then rolled. A cylindrical billet may have the coating deposited on its curved surface and ends or may be coated on its curved surface and after rolling or forging cut to length and coated on its ends. A pipe elbow 20, Fig. 9, with a coating 21 may be formed by forging or extruding in dies a cylindrical billet coated on its surface and ends, the thickness of the coating varying at different parts of the blank, according to the shape of the resulting article.

Title: Improvements in or relating to the purification of cyanuric chloride
Filed: 1961-02-01
Abstract: <PICT:0948271/C1/1> Cyanuric chloride is purified by a process involving melting, distillation, and recovery of the product in solid form, wherein the melt is subjected to fractional distillation in a column, the fractionated product is removed by means of a carrier gas introduced into the column, whereby part of the cyanuric chloride vapour is condensed and returned into the top of the column and the carrier gas and cyanuric chloride vapour are conducted into a separator device, in which the carrier gas and cyanuric chloride vapour, with production of a mixed vortex, and very intimately mixed with an inert coolant, with cooling and deposition of the solid cyanuric chloride. The inert coolant may be a gas or an atomized volatile liquid, e.g. methane, ethane, propane, butane, difluorodichloromethane, methyl chloride, dimethyl ether, nitrogen, hydrogen, oxygen and noble gases, liquid CO2 being preferred.  The carrier gas may be nitrogen, carbon dioxide or a noble gas.  In an example cyanuric chloride 1 is heated to boiling in flask 2 and the resulting vapours are fractionated in column 3. A reflux is produced by condenser 4 which is cooled by a coolant, e.g. pressurized water flowing in at 5 and out at 6. This coolant preferably operates so that the gases leaving the condenser are at a temperature 10-50 DEG C. below the boiling point of cyanuric chloride.  Carrier gas (nitrogen) is introduced just below the condenser at 7.  This gas becomes saturated with cyanuric chloride, and the mixture 8 of the two passes through pipe 9 to a wide chamber 10 in which it is cooled by cold nitrogen introduced at 11.  The cyanuric chloride precipitates on the bottom of the chamber and may be removed at 12, while the carrier gas leaves the chamber at 13 via a dust filter 14.

Title: Process for the joint production of hydrogen peroxide and soluble barium salts from barium peroxide
IPC: C01B15/032
Filed: 1933-02-08
Abstract: Barium peroxide is reacted with phosphoric acid to produce hydrogen peroxide and di-barium phosphate and the di-barium phosphate obtained is then treated with such acids as are volatile and capable of forming soluble barium salts, e.g. hydrochloric or nitric acids, either in the gaseous state or as aqueous solutions, with the regeneration of the phosphoric acid.  The regenerated phosphoric acid may be returned to the process.  According to a modification, the di-barium phosphate is brought into solution by treatment with phosphoric acid, the solution is freed from insoluble impurities and is finally treated with acids of the kind referred to above.  After the separation of the barium salts from the phosphoric acid, e.g. by cooling, it may be freed from the volatile acid by distillation. Hydrochloric acid is preferably employed in excess in order to effect a precipitation of barium chloride.  After treating the di-barium phosphate with nitric acid and separating the deposited barium nitrate, the remaining phosphoric acid may be treated with sodium carbonate to precipitate the remaining barium present and the solution may be finally neutralized with further sodium carbonate to produce disodium phosphate which is separated by cooling.  Examples are given.

IPC: B21H5/02
Filed: 1967-01-26
Abstract: 1,210,411. Making gears or tubes; forging; tube expanding; rolling; embossing; rotary cutter head; lathe details. NATIONAL RESEARCH & DEVELOPMENT CORP. 24 Jan., 1968 [26 Jan., 1967], No. 3986/67. Headings B3A, B3C, B3Q, B3H, B3J, B3M, B3T. A hollow workpiece is plastically deformed by a forming tool, the deformation being assisted by applying to the hollow interior of the workpiece an outward force which generates in the workpiece a tensile stress acting perpendicular to the relative movement of the tool and workpiece. To form gear teeth in an annulus 10, Fig. 3, forming tools 15 are moved towards the blank, while at the same time the blank expands radially under an applied pressure P. The pressure produces a desired terminal stress T to assist in the deformation. The pressure may be produced hydraulically or by a tapered mandrel movable axially relative to the annulus. In place of the tools 15, toothed planetary rollers 17, Fig. 5; may be disposed around the blank 10, the rollers and a meshing annulus 18 being rotated by a common motor 23 through gearing 20, 21. An hydraulic pressure P, which is applied by intensifier pistons 28 under the action of an applied pressure P 0 , acts radially on the blank. An additional axial and radial pressure is applied by pistons 25 having bevelled faces 25<SP>1</SP>. The movement of the two pistons 25 is equalized hydraulically. Straight or helical teeth or splines may be formed by a suitable choice of teeth on the rollers 17.  For forming gear teeth or splines on a tubular blank 10, Fig. 6, similar rollers 17 are used. For producing helical teeth or splines, suitable rollers are used and the blank is rotated. Tensile stress is produced in the blank by forcing it axially over the enlarged portion 56 of a mandrel 54, one or more triming tools 60 finish the teeth, the tools rotating with a planet carrier for the rollers 17. In place of the rollers 17 in each case, an eccentrically rotatable annulus may be employed, or alternatively, the rollers may be provided on their teeth flanks with cutting edges. The tubular blank 10 can be formed with straight or helical splines using rotatable segments 62, Fig. 7, or rotatable discs, the force produced by the tools supplementing an axial F applied to the blank. Where an internal hydraulic pressure is utilized, only cold working of a workpiece is appropriate.
