Abstract: 1479358 Soldering wires to workpieces INTERNATIONAL BUSINESS MACHINES CORP 15 July 1975 [31 July 1974] 29599/75 Headings B5A and B3R A method of routing and bonding pretwisted wires 70 on to a workpiece 26 comprises feeding the wires towards a receiving clamp 18, gripping the wires at spaced positions with the clamp 18 and a further clamp 436, relatively rotating the clamps in a direction opposite to the pitch of the twisted wires to form a loop between the clamps 118, 436, spacing the loop with a bonding unit 22 to establish a pre-determined wire spacing, applying a high level power pulse of short duration to the wires between the clamps to remove the insulation from the wires, and bonding the wires to bonding sites on the workpiece. The workpiece 26 includes a number of circuit cards 28 and cornering posts 44 between the cards. It is secured on a platform 24 of a positioning mechanism 12 and the apparatus is controlled by a programme stored in a computer. The platform member 24 moves the workpiece in an x-direction while a carriage assembly 50 moves a tooling base 16 in a ydirection to orient pads 30, 32 with respect to the bonding unit 22. Pre-twisted wires are fed from a spool 14 through a feed tube 434 of feeding means 20 by operation of a piston adder 420. Clamp jaws 118 are lowered and actuated to grip the wires 70 while the clamp 436 is closed on the wires in the tube 434. A piston adder 426 rotates the clamp 436 and tube 434 via a speed reducer 424 and gears 432, 430 to form the loop. Should it be necessary to reverse the location of the individual wires, the clamp 118 is released and the loop rotated 180 degrees by the piston adder 426. The mechanism 12 is then raised and probe means 302 is lowered so that the wires 70a, 70b enter tips 308, 310, Fig. 4, to establish correct spacing. The probe means is raised and a bond tip 314 lowered to locate the wires on solder pads 30, 32. A short power pulse is applied to the tip 314 to melt the insulation and the power is then reduced to form soldered joints. The clamp jaws 118 are retracted to break off the scrap end of the wires 70 Fig. 7c (not shown). The mechanism 12 is lowered while the clamp 436 is still closed to check the joint by applying a known load unit. The clamp is then released and the mechanism lowered to its starting level. The wires 70 are routed to the next bond point and they are secured around posts 44 by rotation of the tool ing base 16 between the bond points, Fig. 6 (not shown).

Title: Casings for Fluid Control Valves.
Inventor: KAYE OLIVER
IPC: B21C37/29
Filed: 1966-07-04
Abstract: 1,180,029. Making valve casings; angular bending; straightening; stamping; welding by fusion. SAUNDERS VALVE CO. Ltd. 28 June, 1967 [4 July, 1966], No. 29913/66. Headings B3A, B3E, B3Q and B3R. [Also in Division F2] In a method of making a casing for a fluid control valve having a bore which is at least substantially straight through and having a seating formed by an inward taper from an opening on one side and a clamping flange bounding the opening, comprises machining a piece of tube of wrought metal from one side to a dimension to receive the flange and to a depth to form a longitudinal slot in the tube side, applying outward pressure at the mid-length of the slot to open out the sides of the tube, applying further pressure finally to shape the side opening and inward taper, indenting the tube on the side opposite the opening, and welding the clamping flange to the tube. The slotted tube, which may be of stainless steel, is mounted in a fixture comprising a V-block 15 and two end clamps 16, 17. The clamp members 17 are secured by wedges 19 and are provided with tongues 18 which locate on the base of the slot 12. A pair of tongs is dropped into the tube and the jaws 21 thereof are forced outwardly by a wedge 23 thus roughly shaping the inward taper. The final form of the taper is shaped by a former (24) which is driven into the tube through the expanded opening, Figs. 8, 9 (not shown). To straighten the tube, which has been bowed along its bottom by the previous operations, it is placed slot downwards over a central support made to the exact contour of the seating and while so supported a V-block is carried downwardly to indent the tube, Figs. 11, 12 (not shown). This indentation localizes the seating and stiffens and strengthens the tube. The slot is now refaced and deburred to receive the clamping flange and, if necessary, the tube is faced at the ends. The tube is next placed in a welding fixture comprising a former 42 attached to a top plate 41, an outside former 43 detachably attached to the plate 41 and two end pieces 47. The clamping flange is bolted to the plate 41 before the tube is set over the former 42. Welding, which may be carried out electrically, is effected in sequence internally along the edges 48, 49 and externally along the edges 48, 49 and around the circular form. Several runs, e.g. four, will usually be necessary. The component is removed from the fixture and the welding completed by welding inside the flange blending into the welds along the edges 49 and welding on the outside where previously prevented by the former 43. After cooling, the end pieces 47 are removed, the ends are faced and the welds pressure tested. Next, the clamping flange is faced and a blending radius from the flange face to the angular side of the formed tube machined. The tube ends are finally prepared for threaded or bolted end connections.

Title: Improvements in the manufacture of cellulose derivatives
IPC: C08B1/02
Filed: 1938-10-17
Abstract: 520,336. Cellulose esters. DREYFUS, H. Oct. 17, 1938, No. 29988. [Class 2 (ii)] Cellulose organic esters are obtained by treatment of chemical wood pulp with an aqueous solution of an oxygen-containing mineral acid which is free from organic acid and contains mineral acid in such proportion as to incorporate up to 5 per cent. of acid in the pulp and then subjecting the pulp containing the acid catalyst to esterification treatment in a liquid medium. The proportion of catalyst incorporated in the pulp is preferably about 2 per cent. of the dry weight of the pulp. An aqueous solution of sulphuric acid may be used for impregnating the pulp, the excess of solution being removed by centrifuging. The moisture content of the centrifuged material may be reduced by drying, e.g., by blowing air 'through the material. The treated pulp may be subjected to further pretreatments, e.g., with acetic acid or other organic acid in liquid or vapour form, and then converted into a cellulose ester, using acetic, propionic, or other acid anhydride. Esterification may be carried out in presence of an organic acid or other solvent for the ester produced, or in presence of a non-solvent diluent, e.g., benzene or ether. An additional amount of sulphuric acid may be incorporated in the reaction mixture, or another catalyst, e.g., a perchlorate or perchloric acid, may be used. The cellulose ester may be ripened in solution or suspension and may be employed in the production of filaments, films, moulding powders, or other products. Instead of sulphuric acid there may be used phosphoric acid or perchloric acid.
