Title: Improvements relating to metal vapour electric discharge lamps
IPC: H01J5/24
Filed: 1942-11-24
Abstract: 561,281. Glass manufacture. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., ALDINGTON, J. N., and MEADOWCROFT, A. J. Nov. 24, 1942, No. 16605. [Class 56] [Also in Group XXXVI] For attaching a fabricated hermetic seal 7, 8, 9, 10, 11, 12; Fig. 5, for supplying current to the electrodes 2, 3 of an H.P.M.V. or similar lamp, to the bulb 1 of the lamp, the tube 7 of the seal is blown to form a bulb 16 and the bulb is ground in a plane 7, Fig. 1 (not shown), to form an annular section of the same size as a similar section formed by grinding off a tubular extension 14 in the bulb 1. The ends of the tube 7 and bulb 1 are then mounted about a vertical axis and pressed together while being heated during rotation. The tube 7 and bulb 1 are of the same thickness and if necessary extra molten quartz can be added to the join to correct for inequalities of thickness so that the finished article will be substantially equal thickness throughout and so will have no great variations in temperature likely to cause breakage. The electrodes 2, 3 are mounted eccentrically of the bulb also to cause equalisation of the heating. The bulb 16 may be blown of oblate form and the planes at which the grinding of adjacent faces of the parts 1, 16 meet may be inclined so as to produce surfaces meeting at an acute angle, the angular space being filled up with molten quartz. In another form the bulb 16 is so formed that the inside of the cut flared part coincides with the inside of the annular section of the bulb 1, but the outer section of bulb 1 overlaps that of the bulb 16. The tube 7 of the seal envelopes the rod 8 of the anode 2 and the tube 7 is expanded at 9 to form a hermetic seal comprising foils 10 of molybdenum sealed between the expansion 9 and an inner quartz tube 11. The foils 10 are connected by a stout strip 12 of refractory metal to the source of current.

Filed: 1975-04-24
Abstract: 1484758 Tensioning elongate material being wound on running cores INDUSTRIE PIRELLI SpA 24 April 1975 [26 April 1974] 17117/75 Heading B8G In apparatus for winding a flexible elongate element around an advancing elongate element, a reel of the flexible element is held coaxial with, and rotated about, the advancing element, and the flexible element is passed inwards to the advancing element between two at least substantially continuous annular surfaces, coaxial with the advancing element, which are urged together to retard the passage of the flexible element. Downstream of a stranding machine the advancing element 41 comprising one or more insulated conductors, draws yarn 43 from driven reel 39. The running, rotating yarn passes between a ring 23 and two annular ring segments 27, 28, the rotating ring and two segments being urged together, to brake the yarn, by the coplanar end faces of two horseshoe magnets 17, 18 rotating with the reel. Because element 41 is being rotated about its own axis, the yarn sweeps around the ring 23 and displaces the ring from the segments in succession, thus making and breaking electrical contact with the segments to produce a pulse signal. If the yarn breaks, the pulse stops, and the device is stopped or an alarm triggered.
