IPC: B30B9/30
Filed: 1934-05-17
Abstract: 428,503. Baling-presses. KRUPP GRUSONWERK AKT.-GES., F., Buckau, Magdeburg, Germany. May 17, 1934, No. 14963. Convention date, May 23, 1933. [Class 94 (i)] During transfer from a preliminary press to a finishing press the bale is clamped by means of detachable frameworks which retain the bracing plates in position. After the press box 1 has been filled with the material to be baled, e.g. cotton, jute or hemp, the upper bracing plate 7 and cross-head 4 are moved into position on rails 6, 5 respectively and pressure is applied by the ram 3. The hinged side walls are then folded up and the frameworks 12 are applied. These comprise spaced bars 15 on a spindle 16 with connecting members 18, 19, the bars 15 having hooked ends for engaging recesses in the bracing plates 2, 7. The engagement with the recesses in the lower bracing plate is not made until the ram 3 falls, and the bale may then be removed on the rails 6. The frameworks are readily removable after the bale has been further compressed in the finishing press.

Abstract: 600,084. Shearing. WATERBURY FARREL FOUNDRY & MACHINE CO. June 13, 1945, No. 14984. Convention date, Aug. 3, 1944. [Class 83 (iv)] In apparatus for shearing a length of wire, bar stock and the like, the stock stop is adapted to be moved transversely away from its normal position in front of the die opening as the shearing tool advances to sever the material. The stock is fed through a shearing die 14 up to a stop 26 carried by one arm 21 of a L-shaped finger pivoted at 20 to an arm 18 which is mounted on a rod 19 so as to be adjustable towards and away from the face of the die. The finger is urged in a clockwise direction, as seen in Fig. 2, by a spring 30 so as to bring the stop 26 in front of the die opening. On the advance of the shearing cutter 36, a cam surface 45 formed on one side of the cutter bar 35 engages a roller 24 carried by the other arm 22 of the finger so as to rotate the finger in a counter-clockwise direction and move the stop transversly away from its operative position. It is stated that the absence of the stop during the actual shearing operation results in the production of a smooth cut at right angles to the axis of the stock. The forward end of the cutter is formed with a half-round groove 39 which, after the shearing operation, co-operates with a finger 40 hinged to the cutter at 40a to feed the cut blank to a heading die 15.

Filed: 1970-03-31
Abstract: 1286590 Recovery of nickel INTERNATIONAL NICKEL CO OF CANADA Ltd 31 March 1970 [28 March 1969] 15056/70 Heading C1A A process for separating nickel from cobalt comprises precipitating reducible nickel and cobalt compounds from aqueous solution, reducing the precipitated compounds to metal at less than 400‹ C. and converting the nickel to nickel carbonyl by contacting the reduced compounds with CO at less than 100‹ C. and a pressure greater than 1 atm., but less than 15 atm. From 0À2 to 2 moles of sulphur per mole of cobalt may be added to the reduced product to catalyse the formation of nickel carbonyl; the sulphur may be in the form of soluble sulphides, elemental sulphur, H 2 S pyrites, SO 2  or COS and may be added at any stage prior to the carbonylation step. The carbonylation may be carried out in a fluid bed, rotary kiln or multiple hearth furnace. The starting solution may contain iron as well as Ni and Co, in which case some iron carbonyl will be formed along with the nickel carbonyl, and this may be separated by fractional distillation. The process of the invention may be used to separate nickel from laterite ores in which the ore is first either selectively reduced to reduce to metal at least 75% of Ni and Co, but not more than 3 parts by weight of Fe per part of Ni, and the reduced ore leached with ammoniacal ammonium carbonate with aeration to form a solution containing Ni, Co, Fe, or when the ore contains more than 40% Fe, the ore may be leached directly with H 2 SO 4  at 230-260‹ C, in an autoclave to dissolve Ni and Co and limited quantities of iron. After either treatment the solution may be subjected to the process of the invention.

Title: Improvements in or relating to an electric ignition device for a projectile
IPC: F42C11/00
Filed: 1958-05-14
Abstract: 865,153. Ammunition fuzes. BREVETS ELECTRO-MECANIQUES S. A., B. E. M. May 14, 1958 [May 16, 1957], No. 15427/58. Class 9(1). An electric fuze more particularly for unrotated projectiles comprises a varied cap 1 mounted on a shaft 2 passing through the shell casing 3 and carrying a magnet 5 mounted for rotation between armatures 6, 7 around which is a winding 8. One end of the winding is connected through a resistance 9 to a condenser 10 and the other end to a stationary switch element 11. A contact 15 to close the switch is carried by a curved spring blade 12, which, when the shaft 2 rotates, is moved outwards by centrifugal force bringing the contact 15 against the element 11. Also mounted on the shaft 2 are contacts which close due to inertia when the speed of the shaft falls, to discharge the condenser 10 through a primer 23 to explode the projectile. On firing the projectile, the shaft 2 rotates and in each rotation the contact 15 touches the element 11 so that the condenser 10 becomes charged in one sense only, the resistance 9, which preferably can be regulated, serving to control the charging time to provide a safety margin for the launcher. On impact the shaft 2 is braked suddenly and in consequence a blade 19 carried by a conducting sleeve 20, mounted by means of insulation 21 on the shaft 2, moves away from an insulating stop 17 into abutment with a contact 18. Stop 17 and contact 18 are carried by a plate 16 which is in electrical connection with the shaft 2, the shaft 2 being connected electrically to the casing by a contact blade 22. When the blade 19 touches the contact 18, the circuit from the condenser 10 through the primer 23 and a contact 24 touching the sleeve 20 is completed. In parallel with the primer is a high resistance 25, so that if ignition does not take place on impact the condenser discharges through the resistance 25 and after a given time the fuze is disarmed. When the fuze is used in bombs transported beneath an aircraft, means projecting from the suspension are provided to prevent rotation of the cap 1 until the bombs are launched.

Inventor: CLARK LEONARD JACK
IPC: H02K47/22

Abstract: 712.372. Dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd- May 7, 1953 [June 20, 1952], No. 15603/52.- Class 35 In an A.C. generator having no sliprings, the stator is D.C, excited to a certain number of poles and A.C. is derived from a stater winding of a different. number of poles, the rotor carrying a closed winding having both pole numbers. As described, the D.C. excitation produces four poles, this excitation of the rotor winding producing an 8-pole field revolving relative to the rotor, preferably in the opposite diretion, this field in turn giving rise to the A.C. output at the stator. The currents induced in the rotor windings are 4-pole and in accordance with the invention it is necessary for these currents to function as 8-pole currents at the same time. The number of amp-conductors in each rotor slot must therefore be at every instant the resultant of a set of four-pole and eight-pole amp-conductors. The addition of the four-pole and eight-pole windings is shown, for a repeating section of winding, in Fig. 2, in which the numbered points on the inner circle mark the extremities of time vectors representing the four-pole amp-conductors in the slots of those numbers. The numberd points on the outer circle mark the extremities of the time vectors representing eight-pole amp-conductors, the two rotations being opposite. The two amp-conductor vectors in each slot are added and the resultant slot-amp-conductors are represented by the ringed numbers on the three-lobed curve in broken lines. Fig 3 shows how the triple lobed curve is resolved into components on pairs of the phase axes A, B, C. For example, the amp-conductors in slot 1 are resolved into vector A1 in phase axis A and vector B1 in phase axis B. It can be seen that vector B1 is equal and opposite to vector B12 so that the two sides of a single coil may be used and similarly all the component vectors may be paired off tc form opposite sides of coils of a three-phase winding. Since the conductors in each phase are connected in series and the phases are balanced, the length of the component phase vectors represent the number of conductors in each slot. The stator may carry a damping winding which may be sinusoidally distributed. Specification 660,064 is referred to.
