Patent GB-1014065-A (GB)
Title: Magnesium metaphosphate
Inventor: RAITT JOHN STEWART
IPC: C01B25/44
Filed: 1963-10-07
Abstract: Granular magnesium metaphosphate is produced by applying an aqueous solution or slurry containing magnesium ions and one or more phosphate ions which have the formula H2(PnO3n+1), where n is less than 8, and which may be derived from orthophosphoric acid, to inert paticles undergoing recirculation in a reaction zone to coat them with successive layers of the solution or slurry.  The coated particles are subjected in the reaction zone to a temperature of between 250 DEG  C. and 500 DEG  C. so that each of the layers is individually dried and molecularly dehydrated to form a solid layer of magnesium metaphosphate, the rate of recirculation, rate of addition of solution or slurry and particle temperature being maintained such that the particles retain their discrete identities throughout circulation within the reaction zone.  The circulation and addition of solution or slurry is repeated until the desired quantity of granular product is obtained. The inert particles preferably consist of magnesium metaphosphate as produced by the above process. The solution or slurry, which preferably contains magnesium and phosphorus in an atom ratio of between 0.9: 2 and 1.5 to 2, may contain additional ions which under the reaction conditions are volatile, for example carbonate and chloride ions, or are non-volatile, which latter ions are present in an amount of less than 10% by weight of the final product. The solution or slurry may be prepared by adding magnesium oxide to a solution containing phosphate ions to which is added a volatile acid, for example hydrochloric acid, which prevents the precipitation of undesirable magnesium phosphates, in an amount substantially less than that necessary to convert the magnesium oxide to the salt of the acid. Preferably, the ratio of the rate of recirculation to the rate of addition of the magnesium and phosphate ions to the solution or slurry is at least 20: 1 on a weight basis.  The process may be carried out on a batch principle or in a continuous manner, for example in a granulator described and claimed in Specification 907,900.

Title: Improvements in or relating to autographic registers
Inventor: GILL EDWARD WILLIAM
IPC: B41L5/04
Filed: 1969-08-13
Abstract: 1,254,913. Autographic registers. LAMSON PARAGON Ltd. 13 Aug., 1970 [13 Aug., 1969], No. 40463/69. Heading B6A. In an autographic register having a support member 4 with pins 5 for engaging perforations 24 near the leading edge of continuous stationery webs and movable to feed the webs forwardly, an arm 9 for moving the member 4 has its operative movement obstructed so that it has first to be moved in a direction at an angle to the operating movement to be freed from the obstruction before it can be given an operative stroke. As shown, the lever 9 abuts against a flange 12, Fig. 5, on the machine frame and is made flexible so that to effect feed of the stationery it has to be bent sideways free of the flange 12 and then moved forwardly. A spring 9a biases the lever 9 to its initial position. Each pin 5, Fig. 4, is mounted in a recess 17 integral with'the member 4 and has springy hooked ends 22 which are pressed together to permit of the insertion of the pin and which limit the upward movement of the pin under the action of a spring 23. The members 4, 9, are fixed to a shaft 7. A concave plate 8 overlies the tops of the pins 5 and can be pivoted upwardly about one end as shown in Fig. 2 to permit the perforations 24 to be'placed over the pins 5. A slot' (25, Fig. 7) is provided in the forward edge of each pin to prevent the stationery from sliding off the pin. After entries have been made on the leading form length, the lever 9 is operated as described above and the stationery is moved forwardly by the pins 5. During the latter part of such movement, the rear part of the support 4 lifts the stationery off the pins 5 so that the leading form length can be withdrawn by hand. When such withdrawal is begun, the lever 9 is released, allowing the pins 5 to return to their initial position where, in co-operation with the plate 8, they cause the stationery to be tensioned as it is withdrawn, until they enter the perforations 24 of the next form length. The leading form length is now torn off across a transverse perforated line and along the edge of the plate 8. A hinged cover 14, Fig. 2, has a slot 15 to accommodate the lever 9 and also has a pad 16 which rests on the stationery to keep it flat. A drawer, in which to place copies detached from the stationery webs, is mounted in the base of the register and is urged to open position by a spring. A lever 36, Fig. 5, biased by a spring 37 engages a flange 35 on the drawer to hold the drawer closed. When the lever 9 is moved forwardly, it engages the lever 36 and releases the lever from the flange 35 so that the drawer moves to -open position. The drawer can be opened independently of the lever 9 by lifting a lug 40 on the lever 36 by means of a tool inserted through an aperture in the casing. A pivoted knife 41, Fig. 2, is provided on the register to cut off used portions of transfer webs extending transversely of the stationery webs.

Abstract: 1,061,439. Control of motors. BORGWARNER CORPORATION. Oct. 15, 1963 [Nov. 28, 1962], No. 40622/63. Heading H2J. [Also in Divisions G1 and H4] The temperature and the fluid pressure existing at a distant electric motor 12, Fig. 5 (e.g. for drilling at the foot of a well) respectively operates a bimetallic switch 41, and moves a resistance slider 42, the resulting signals being superimposed by means of a bucking transformer 38, 39 upon the power supply lines 15a, 15b, 15c, and being detected remotely by means of a second bucking transformer 43, 44 at the power source 16. The variable resistance 42 in series with a battery 40 varies the current in the secondary 39 of the first bucking transformer, and the full battery voltage is applied between the conductors 15a, 15b, when the bimetallic switch closes, the latter providing an indication of excessive temperature. The receiver ineludes a D.C. detector such as a voltmeter 46, or a relay coil 47 which would cut out the motor supply in the case of excessive temperature. If only a variable resistor is used at the motor, Fig. 4 (not shown), the battery 40 may be omitted.

Title: Welding a wire to terminals
IPC: B23K11/16
Filed: 1973-08-29
Abstract: 1445826 Welding by pressure CALIFORNIA INSTITUTE OF TECHNOLOGY 29 Aug 1973 [30 Aug 1972] 40720/73 Heading B3R In welding a continuous wire to a number of terminals the wire is guided across the face of a welding member by guide means located on opposite sides of the face, the member is pressed against each terminal in turn while applying welding energy thereto and the member and guide means are moved relatively up and away from a terminal at which the wire has just been welded to a next successive terminal. In an embodiment the welding apparatus for welding a continuous insulated wire 12 to terminal pins 14, Fig. 2, of circuit board 16 comprises an electrode assembly 18, a holder for a spool of wire 12, a source for supplying welding current to the assembly 18 and a drive unit, operated by a programmed controller, for moving the assembly 18 over the board 16 and down towards and away from the terminal pins 14. The assembly 18 includes an inner electrode 30, an insulator 32 about the electrode 30 and an outer electrode 34 concentric with the inner electrode. The inner electrode has a tip 36 of tungsten carbide held in a rod 38, the tip having a concave wire abutting surface 42 and the outer electrode having an extension tubular portion 40 having a pair of opposed openings 46, 48. The wire extends through the openings 46, which is merely a hole, across the face of the tip 36 and through the opening 48, which is a slot, to the previous terminal. In use the assembly 18 is lowered so that the pin 14 is received in the bore 44 of the portion 40, the electrode assembly is pressed downwardly so that the inner electrode ruptures the insulation on the wire and current is passed through the electrodes to weld the wire to the pin. The electrode assembly is then lifted from the pin and moved over the board to the next pin, the wire being payed out from the spool. For welding the wire to pins which are not in line the assembly is first moved from a pin along a line parallel to that along which the wire extends across the face of the inner electrode before moving laterally towards the next pin. The board may be moved instead of the pin or both may be moved. In a modification the outer electrode may be mounted on bearings so that it can rotate relatively to the inner electrode so that the guide openings can be aligned with the trailing wire. In this case a slip-ring supplies current to the outer electrode which may be rotated by a motor. Switches on opposite sides of the wire guiding slot sense deviation of the outer electrode from a desired direction and control the motor to rotate the outer electrode. In a further modification an electrode 70, Fig. 7, presses the wire against the pin 14, the wire being guided by openings 78, 80 on opposite sides of an insulating member 76 about the electrode 70, and a separate electrode 72 presses against the bottom of the pin 14. Reference is made to supplying electrical, ultra-

A reciprocating scraper is provided for removing hard carbon deposits from the wall electrode of a rotary-arc furnace carrying out continuous vapour phase-reactions. As shown a rotary are is formed between a carbon cathode 3 and the water-cooled walls of a copper anode tube 1 surrounded by a magnet coil 11, and in a process such as the dehydrogenation of hydrocarbons a hard carbon deposit forms in the region 40. A water-cooled copper scraper 20 mounted on tubes 24, 25 is reciprocated periodically by a rack and pinion 29, 30 to remove the carbon from area 40 during the reaction. The arc temporarily transfers from wall 1 to the scraper, and then returns to the anode wall as the scraper retracts. When not operating in the arc region the scraper may be used for removing the fluffy carbon deposit which forms upstream of the arc. The polarity of the electrodes may be reversed and operating conditions adjusted so that the hard carbon deposit forms on the cathode.

In a TDM, PBX having one or more operators' positions, calls to such positions are formed into a queue in the event that the positions are all busy. When a position becomes free the first call in the queue is directed to it. The system includes rotary memories for storing the addresses of the calling party, the called party, the operators, the free/busy state of the latter, the callers in the queue, &c. An incoming (from main exchange) call may be extended directly to an extension in response to inward dialling signals. If the extension is busy or does not reply within a certain time however the call is diverted to an operator-via the queue if necessary. The order in the queue may be governed, by the priority of the caller e.g. incoming exchange call ranks higher than any other type of call, by the order of arrival of calls, or by the order in which free time slots are allotted to the calls (this particular order may be varied from frame to frame or after the call at the head of the queue has been answered by, in effect, shuffling the time slots).
