Patent GB-716374-A (GB)
Title: Dielectric heating apparatus for use in producing hollow structures from sheet material
Inventor: DOWNING ROY KENNETH
IPC: B29B13/00
Filed: 1951-03-01
Abstract: 716,374. Dielectric heating. COMMUNICATIONS PATENTS Ltd. May 30, 1952 [March 1, 1951], No. 4993/51. Class 39 (3) [Also in Group VIII] In producing hollow structures such as trays and boxes by folding a sheet of material. e.g. cellulose acetate, and welding overlapping parts by dielectric heating, the pre-folded structure is arranged over a former carrying electrodes 17 which are relatively movable to adjust their positions to suit structures of different sizes. The electrodes 17 co-operate with electrodes fixed on a table top. The former may carry two pairs of electrodes adapted to come within the hollow structure, and the relative spacing of all four electrodes is adjustable for different hollow structures. The spacing apart of individual electrodes of each pair is adjustable and the spacing of the two pairs of electrodes is also adjustable. Mounted on the edge of a table is a pair of normally fixed electrodes,. towards and away from which the former carrying electrode 17 is reciprocated on a pin 1 extending through a slot in the table and engaging a coupling member 2 on the former. The pin 1 is reciprocated by a pedal whereby the former is moved over the table top. The coupling member 2 has diametrically opposed arms 3, 4 each carrying a transversely extending electrode carrier 8. Metal plate electrodes 17 on blocks 18 of insulating material are adjustably clamped on rods 14 along the length of the carrier to suit the width of a hollow structure. Arms connecting the transverse carriers are adjustable in length or interchangeable with arms of different length so that the electrodes may be spaced according to the length of the hollow structure. The electrodes are thus adjustable to the four folded corners of a hollow structure, and after sealing two corners by dielectric heating, the former is moved back and rotated through 180 degrees about the pin and then moved forward to seal the other corners. Alternatively, the coupling member may have a single arm with one transversely extending carrier on which one pair only of electrodes 17 is spaced, so that after sealing two corners, the hollow structure is removed from the former and replaced with the other junctions adjacent the electrodes. Specification 670,808 is referred to.

Abstract: 551,143. Punching. BRITISH THOMSONHOUSTON CO., Ltd. April 16, 1942, No. 5042. Convention date, April 17, 1941. [Classes 83 (iii) and 83 (iv)] An indexing device for use in a punch press is described with reference to punching slots in laminations and has means for applying a torque to the indexed spindle in a direction opposite to that imparted by the indexing pawl to prevent rebound from the tooth of the locating detent pawl and thus enable the press to be run at increased speed. The disc 10 is located by a keyway on the key 121 of a spindle 12 and clamped by a head 73 on a swinging arm 75 on a rise and fall rod 74. The spindle carries a ratchet wheel 11 engaged by a detent 19 on a bolt 20 kept in engagement with the wheel by springs 22. The bolt slides in guides in a head adjustable on a bar 23 carried by a disc 24 loose on the spindle and clamped at 27. The spring- controlled index pawl 28 is similarly mounted on an arm 32 actuated by a rod 34 from a bellcrank linked to a crank pin on the end of the press shaft. A gear 46 formed with clutch teeth 47 is loose on the spindle but is coupled thereto by a clutch 48 splined on the shaft and normally held engaged by a spring 68 acting through a yoke lever 63. The gear drives a rack 45 that through a pinion 44 drives a rack 43 that moves a piston 41 in a cylinder against opposing fluid pressure. The strokes are long enough to permit a complete rotation of the gear and the punching of all the notches in the disc of the panel 13. A dog 53 then operates a valve 54 causing a piston rod 59 to rise and disengage the clutch through linkage 60, 62, the clutch being held in the disengaged position by a latch 66. The piston 41 then returns the parts to their initial position when a dog 69 trips the latch causing re-engagement of the clutch.

Title: Improvements in or relating to separation of nickel and cobalt from acidic solution
IPC: C22B23/00
Filed: 1953-03-02
Abstract: High purity cobalt is separated from substantially copper-free and iron-free solutions containing cobalt and nickel by adjusting the hydrogen ion concentration of the solution to less than that equivalent to a full acid content of 5 per cent, treating the adjusted solution with a compatible electrolyte, that is an acid or salt soluble in the solution without causing premature precipitation or crystallisation of any dissolved component, and with a soluble salt-forming acid-neutralising agent such as ammonia to produce, after reduction, a hydrogen ion concentration ranging from that equivalent to a full acid content of from 0,2 per cent for Ni:Co mol. ratios of 5 : 1 and higher to that of a 1,0 per cent solution of Ni:Co mol. ratios of 1 : 1 to 1 : 10. The resulting solution is then treated with a non-sulphidising reducing gas at temperature above 250 DEG F. to reduce the nickel to metal, the precipitate is removed and the remaining solution is treated at above 300 DEG F. and at a hydrogen ion concentration less than that of a free acid content of 0,5 per cent with a non-sulphidising reducing gas for sufficient time to precipitate the cobalt.  When the initial solution contains nickel and cobalt in mol. ratios of 3 : 1 to 1 : 5 or less the precipitation may take place in three stages with adjustment to give a hydrogen ion content, after reduction, equivalent to a free acid content of 0,5-1,0 per cent, precipitation of nickel, addition of further acid neutralising agent to reduce the hydrogen ion content, after reduction, to that equivalent to a free acid content of 0,2 per cent for a 3 : 1 ratio to that of 0,3 per cent for a 1 : 5 ratio or lower. For solutions containing Ni and Co in mol. ratios from 1 : 1 to 20 : 1 the hydrogen ion concentration is adjusted to not less than that equivalent to a free acid concentration of 0,5 per cent for a 1 : 1 ratio down to neutral conditions for a 20 : 1 ratio before treatment with a reducing gas at temperatures above 250 DEG C. to precipitate nickel.  The solutions, after adjustment, preferably contain at least 0,2 mols/litre of ammonium sulphate.
