Title: Improvements in or relating to the production of glass threads
IPC: C03B37/09
Filed: 1945-12-11
Abstract: 605,002. Glass threads. VERSIL, Ltd., and LAYCOCK, W. H. Dec. 11, 1945, No. 33502. [Class 56] [Also in Group XI] Small separate fusion receptacles of platinum or other suitable non-oxidisable metal, for producing glass threads, are connected one to another by electrical connecting members to form a conducting chain, the extremities of which are connected to the poles of a source of electric current. As shown, a series of fusion receptacles 1 of platinum or the like are connected by conducting bars 2 of non-precious metal, and the ends connected to a source of electric current. A glass rod 4 of approximately 2 to 5 mms. diameter, and which can be elongated by joining to other rods, is introduced into each receptacle whose height is 4 to 7 mms., with the opening 3 of about 2 mms., and heated to about 1000‹ C. The glass melts and threads f are drawn. Insulating plates 5 and 6 prevent radiation and possible remelting of the thread, while plates 10 form a chamber 11 at each receptacle whose temperature is regulated by means of the adjustable air passage 12. Threads of less than 5 microns diameter may be made. The receptacles may be arranged in any shape, e.g. concentric circles, spirals, for yam production.

Abstract: 1,268,005. Spring-loaded central coupling buffers. MINISTERIUM FUR VERKEHSWESEN. 3 July, 1969, No. 33636/69. Heading B7T. A spring loaded traction and buffing gear for a central buffer coupling comprises a two-part main spring 8, 9 divided by a disc 18 secured to a rod 3, a spring housing 11 and an auxiliary spring 5 contained in a pot 7, such that the spring 9 is held between plates 23, 24 variably separated from each other by a bolt 22 and held between the disc 18 and base 10 of the housing 11, and the spring part 8 is held between the disc 18 and a pressure piece 15 having an extension 27 slidable within the housing 11, while the spring 5 is series connected to the springs 8, 9 by being held between pressure discs 4, 6 within the pot which has a flange 26 set against a shoulder on the pressure piece 15. The rod 3 has a fork end 31 connected by a bolt 2 to the end 1<SP>1</SP> of a coupling arm 1. On buffing, the compressive force is transmitted via the arm 1, rod 3 and disc 4 to the spring 5 which is compressed until the end 12 of the arm 1 reaches a thrust plate 13; further compression is effected by the plate 13 acting on the pressure piece 15 whose extension 27 slides within the housing 11 to compress the springs 8, 9, the limit being when the piece 15 reaches stops 16 on the housing 11. A traction force is transmitted by the arm 1, rod 3 and disc 18 to compress the spring 8, a spacer tube 19 between the discs 18, 6 preventing extension of the spring 5 by moving the disc 6 by the same amount that the disc 4 moves with the rod 3.

[Class 137] Air to be supplied to an enclosure is conditioned at a central plant 20 and then conveyed to local distributing stations 22 where it is mixed with air withdrawn from the enclosure in the region of each local station and the mixture is then discharged into each local region. The supply piping 21 from the plant 20 can thus be made of small diameter as only a small amount of highly conditioned'air will pass therethrough. The units 22 comprise a fan chamber into which conditioned air is drawn through connections 23 and air from the enclosure through connections 36. The fan then supplies air to the enclosure through pipes 37. The conditioner 20 may also be supplied with recirculated air through connection 101. Dampers 31 are provided in connections 23 which may be controlled by thermostats 32. The units may be disposed in various rooms of a building instead of in various parts of a theatre as shown.

As shown, the bath or wash basin unit has a central discharge spout and a second outlet 35 for connection to a sprinkler or shower, these outlets being controlled by a changeover valve 43, 46 up to which the hot and cold passages extend. The body may comprise a central part and two side parts each of which can be fitted to either side of the central part. The changeover valve may be replaced by a known hydrostatic valve such that when the inlet valves are open and an additional valve controlling the shower or sprinkler is also open, then water is discharged through the shower or sprinkler, and on closing the additional valve, water is discharged through the discharge spout as a result of automatic operation of the hydrostatic valve.

An isolating switch has a pair of fixed spring clip contacts 48, 92 supported on spaced insulators 32, 36 and a pivoted blade 42 bridging them. The blade is rotatably mounted in a hinge member 72 mounted to pivot about a fixed axis 84, perpendicular to the blade 42, in a bracket 80 on the insulator 36. An arm 90 extends at 45 degrees to the blade 42 and is pivoted to a crank 52 on a rotatable insulator 34. As insulator 34 is rotated to open the switch, the blade turns about its own axis to free the contacts 48, 42A and about axis 84 to separate them. Connection between contact 92 and blade 42 is maintained after they separate by a conducting C-shaped spring (112) interposed between the hinge member 72 and blade 42, preventing sparking at the hinge. Bronze sleeve bearings (142, 144) coated with low friction P.T.F.E. are located on either side of the spring (112) between the hinge member 72 and blade 42.
