There may be a plurality of magnets 4a and 4b spaced across the width o: the belt (Fig. 5, not shown). There may be a plurality of inductors 5 (Fig. 6, not shown) There may be a third magnet 4c spaced aheac of the magnet 4a, a distance equal to the distance between the magnets 4a and 4b (Fig. 8, not shown). This defines a reference distance which does not increase in length as the joint extends, since the magnets 4a and 4c are both disposed quite clear of the joint. There may be two inductors 5a, 5b, spaced apart a distance (in the direction of conveyance) equal to the distance between the magnets 4a, 4b (Figs. 7 and 10, not shown). The reference distance and the lengthened distance of the belt joint may thus be displayed simultaneously one above the other on the cathode-ray tube 6 (Fig. 11, not shown). The degree of extension of the length of the belt between the magnets 4a and 4b may be computed digitally (Fig. 12, not shown), and the output may be used to operate an alarm or, to stop the belt when the joint extension has exceeded a predetermined amount. There is an arrangement corresponding to Fig. 8 (not shown, but referred to above) which has a digitally operated control circuit similar to that mentioned above (Fig. 13, not shown). There may be two separate digital output circuits respective to the two inductors 5a, 5b (Figs. 15 and 16, not shown). Instead of separately embedded magnets 4a, 4b, they may be in the form of magnetized portions 2a, 2b of the steel rod reinforcements 2, of the belt (Fig. 18, not shown). A method for magnetizing the reinforcements is described (Fig. 19, not shown). A method for de-magnetizing the reinforcements 2 (to remove residual magnetism) is described (Figs. 20 and 21, not shown).

Abstract: 623,650. Discharge apparatus. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and ALDINGTON, J. N. Dec. 11, 1946, No. 36586. [Class 39 (i)] The invention relates to a method of sealing a conductor through an envelope of quartz or vitreous material and is particularly suitable for metal vapour lamps carrying a current greater than 250 amps. in which the pressure is greater than one atmosphere. A rod A, which may be of tungsten, is surrounded over part of its length by a layer of sealing foil B which may be of molybdenum 20-25 microns thick. The foil has an overlapping edge J and at the opposite side from J the quartz tube H has a side tube extension C which is closed, as shown by the dotted lines. A rod F, which may be of copper, rests inside C and carries a blob of silver solder G. The tube H is exhausted and then collapsed on to the foil B in known manner to make a gas-tight joint. The solder G is then melted to make a connection between the sealing foil and the rod F. Alternatively, the foil may have an aperture and the rod F is then sealed direct to rod H, the solder filling the aperture to make a vacuum-tight joint. Finally, the portion of the side branch shown dotted is cut away to expose the lead-in conductor F. Instead of a side tube C, the tube H may have a side aperture formed either before or after the tube is collapsed on to the sealing foil.

Abstract: 970,319. Two-part couplings. CANNON ELECTRIC CO. Oct. 12, 1961 [Nov. 7, 1960], No. 36624/61. Heading H2E. A coupling device (Fig. 3) comprises a plug member 103 including a sleeve 130 and a receptacle member 102 in the form of a tubular sleeve, both members housing contacts, with a locking element, e.g. a ball 122, mounted in the receptacle sleeve and confining means such as constricting lips 123, 124 integral with said receptacle sleeve preventing escape of the element yet providing for limited free movement thereof radially of this sleeve so that in one radial position the element operates as an axial engagement stop for the plug and receptacle members. The coupling members are separated by axial displacement of a collar 145 with a flange thereon abutting an annular ring 154 held away from a flange 153 on the plug sleeve 130 by an annular marcel spring 152 so that with the collar moved back, axial displacement of the plug member cams the ball 22 out of the groove 140. Radial registry of the coupling members is effected by co-operation of a spline 151 in the external face of the plug and a slot 150 in the receptacle wall. In a modification, Fig. 8, the plug sleeve 230 is formed with a smooth external surface so that upon its insertion into the receptacle sleeve the balls (or detents) are forced radially outwards. Locking is effected by engagement of the balls in fragmentary helical grooves 232 (Fig. 10, not shown) in a locking ring 204. Full rotation of the locking ring introduces the balls into sockets 236 offset from and at the end of the grooves 232 with a snap-action augmented by a marcel spring 152<SP>1</SP> thus interlocking the coupling members against inadvertent reverse rotation. Relative rotation between the coupling members is prevented by co-operation of a key 150<SP>1</SP> in an associated keyway 15<SP>1</SP> (Fig. 9, not shown).
