Title: Improvements in and relating to connecting tubes together
IPC: B21D39/04
Filed: 1923-04-05
Abstract: 218,717. Marine & Locomotive Superheaters, Ltd., (Compagnie des Surchauffeurs). April 5, 1923. Steam generators.-A number of parallel tubes are connected together at one end in one operation by forcing into the ends which are previously heated to welding temperature, a mandrel having a corresponding number of branches, which are shaped so as to compress and weld the tubes between the branches, then cut the tubes and open out the cut portion to form a common junction piece. The tubes are held at a distance from the end where they are cold and may be placed in a two-part die prior to formation of the junction to equalize the thickness of the junctionpiece. In joining four parallel tubes a mandrel b, Fig. 13, having a central bore and four tapered branches is used which first compress and weld adjacent tubes together as shown in Fig. 16. The tubes are then severed by the mandrel at the junction of the branches, and the outer wall then pressed out by the mandrel as shown in Figs. 15 and 14, and the central portion compressed to form a stem a<2> which may be afterwards cut off. In joining four parallel tubes to a central tube of larger diameter the mandrel b, Fig. 33, is formed with five tapered branches, the tubes being welded as shown at Fig. 37, cut and the walls opened out as shown in Fig. 36, until the junction-piece is shaped to the form shown in Fig. 34. In all forms the surfaces of the branches of the mandrel adjacent their junction 51 are flattened at 52 as shown in Fig. 39 to ensure the cutting of the welded portion and one branch may be larger than the others. Specification 6304/15, [Class 83 (iv), Metals, Working], is referred to.

Title: Improvements in ion-exchange processes
Inventor: ARDEN THOMAS VICTOR
IPC: C02F1/42
Filed: 1953-04-07
Abstract: 751,855. Electrodialytic decomposition of salt solutions. PERMUTIT CO., Ltd. March 29, 1954 [April 7, 1953], No. 9418/53. Class 41. [Also in Group I] Ion exchange material is regenerated by passage of a solution of an acid in the case of cation exchange material or a base in the case of anion exchange material. The effluent regenerant, which contains a salt together with some excess of acid or base is electrolysed in a cell comprising two or more compartments, separated from one another by one or more diaphragms of ion exchange material, to produce the acid and base of the salt. The acid and/or base is or are used for regenerating further ion exchange material. The process may be carried on in batch fashion or continuously. The Figure shows a bed of cation exchange material 2, which has taken up sodium ions, being regenerated with sulphuric acid. The effluent regenerant is placed in the cathode compartment 4 of a cell 6 in which the diaphragm 8 is of anion exchange material. The anode compartment 5 contains water. Electrolysis causes sulphate ions to pass through the anion exchange diaphragm 8 into compartment 4 to form sulphuric acid and free oxygen at the anode. In compartment 5 sodium hydroxide and free hydrogen are formed at the cathode. The diaphragm 8 may be made of cation exchange material instead of anion exchange material, in which case the effluent regenerant must be placed in the anode compartment. The use of a three compartment cell is described having an anion exchange diaphragm near the anode and a cation exchange diaphragm near the cathode and wherein the effluent regenerant is placed in the centre compartment, acid being formed in the anode compartment and base in the cathode compartment. Specification 751,856 is referred to.

Title: Improvements in or relating to Automatic Weft Replenishing Looms.
Inventor: WADE HAROLD
IPC: D03D49/70
Filed: 1919-04-14
Abstract: 136,441. Wade, H., (Hopedale Manufacturing Co.). April 14, 1919. Weft, cutting.-A weft-cutter for use in automatic weft-replenishing looms comprises cutterblades movable rearwards and forwards and arranged to engage a weft thread extending laterally from the selvedge as they move rearwards in a closed position and to direct the weft thread into position to be received between the blades as they open. As shown, an upper blade 14 is pivoted at 18 between parallel members. forming the lower blade 15, which is arranged to slide on a lug 20 projecting from a support 21 bolted to the temple head, the temple rod 4 being moved forwards on a guide 9 by the lay 8 acting on a heel 7 and rearwards by the usual internal spring. The blade 15 has a heel 27 with a pin 30, which is acted upon by a spring 28 to move the blade 15 rearwards until a shoulder 38 meets the lug 20. In this position, a roll 33 on a pin 34 fixed in the support 21 acts on a cam-part 32 of the blade 14 to raise this blade, a shoulder 35 thereon contacting with the upper surface of the blade 15. When the lay 8 strikes the heel 27, the blade 15 is pushed forwards, carrying the blade 14, which is closed by the action on its upper surface of the roll 33. As the lay retires, the closed blades move rearwards, and their rear bevelled edges 37 are in position to engage and guide to their point of divergence either the outgoing weft end extending from the selvedge to the feeler cutter and clamp or the incoming weftend extending to the hopper stud. A slight tension is put on an engaged weft end so that it snaps forward between the blades when they open and is cut when the blades close on their forward movement.

Abstract: 329,095. Kauffman, A. M. A. von. Dec. 22, 1928, [Convention date]. Compensating for wear. -A step-by-step device for automatically taking up undue play in the actuating - means of vehicle brakes comprises lugs on a rocking actuating-member co-operating with a ratchet-toothed rotary nut or screw, the lugs, which are operative alternately in opposite directions of stroke, being so spaced apart that movements of less than a certain magnitude are ineffective. As applied to brake control means (Figs. 2 and 3), in which a brake rod 5 passes through a hole 4 in a transverse bolt or spindle 3 rotatably mounted in a lever arm 2 on a pedaloperated shaft 1, a nut 6 threaded on the rod to provide for adjustment is formed externally with ratchet teeth 10 and is automatically rotated a step at a time by engagement therewith of lugs 8, 9 on the adjacent faces of flanges 7 forming an extension of the arm 2, such engagement however only taking place when the movements of the arm exceed a certain magnitude. To obviate jamming if the point of a tooth catches the edge of the lug 8, the bolt 3 is axially slidable in the flanges 7. In the arrangement shown in Figs. 12 and 13, brake shoes 11, 12, normally operated by a rotary cam 16, are provided with adjustable ends in the form of screw studs 19, 20, the heads of which are formed with bearing surfaces 15 and peripheral ratchet teeth 21, 22 adapted, when the play becomes excessive, to be engaged and rotated by pairs of lugs 23 on the faces of discs 18 secured to the cam 16. Jamming is obviated by axial movement of the cam and discs relatively to the studs.
