Title: Improvements in or relating to glass manufacture
IPC: C03B5/18
Filed: 1963-09-05
Abstract: <PICT:0988418/C1/1> <PICT:0988418/C1/2> <PICT:0988418/C1/3> A method for deflecting towards at least one of the side walls of a glass melting tank the silicose-rich melt residues which cover the central zone of the glass bath while the glass cooled in the working zone is returning in counter-current towards the charging zone, is characterized in that the cooled glass coming from the working zone is channelled and guided to at least one of the side zones of the melting tank.  A melting tank having a melting zone 6, charging zone 2, refining zone 7 and working zone 8, has a wall 13 between the floaters 9 and the charging zone which extends between the side walls 10, 11 and rises from the tank bottom to a little below the glass surface.  The wall 13 may be terminated at either end before reaching the side walls, or if extending to the side walls has openings 19 at the bottom adjacent the side walls. Returning walls 14, 15 from the wall 13 form a channel along the side wall through which any glass current returning from the working zone must pass, thus leaving central area of melted glass undisturbed by these counter currents. To isolate completely the central zones from any of these currents the walls 14, 15 may be joined by another wall 21, or 211 parallel to wall 13 and located nearer to the charging zone.

Abstract: 396,039. Variable-speed ratchet gearing. MATHEWS, C. D. C., Goondi Mill, Innisfail, Queensland, Australia. Dec. 21, 1931, No. 35279. [Class 80 (ii).] In a variable-speed ratchet drive, a shroud 33 is oscillatably mounted about the ratchet wheel 32 and oscillated with the ratchet'wheel during the operative stroke of the pawl 30 there being means for adjustably controlling the extent of the return oscillation of the shroud to regulate the next engagement of the pawl with the ratchet wheel. The device is regulated by hand or automatically by an oscillating feeler arm 10 adapted in one direction of motion to contact with the bed of fuel on a furnace grate 14. The shroud 33 has a slot 36 through which the pawl 30 on a bell-crank lever 28, continuously driven through a connecting-rod 6 from a disc 5, engages the ratchet wheel 32, and has also a lug 37 adapted to be engaged by a pin 31 on the other arm 27 of the bell-crank lever simultaneously with the engagement of the pawl 30 with the ratchet wheel so that the shroud is rotated with the ratchet wheel. The shroud is connected by a link 7 with a disc 39 connected by a link 9 to the feeler arm 10 pivoted in the furnace at 11 so that during the operative stroke the end 15 of the feeler is lifted from the fuel bed. On the return oscillation the end 15 of the feeler descends and returns the shroud to a position determined by the depth of the fuel bed. To predetermine the desired depth of bed to be maintained the disc 39 is rotatably mounted on one end of a lever 40 pivoted to the casing and having a handle 41 which may be locked in adjusted position on a quadrant 42 by a clamp 43. Adjustment of the handle 41 raises or lowers the disc 39 to vary the position of the path traced out by the rocking feeler 10. For hand regulation, the link 9 is released from the disc 39, a pawl 44 turned to engage a peripheral recess 45 in the disc 39 and a tension spring 46 attached between lugs 47, 48 on the arm 27 and shroud 33 respectively to cause the shroud to follow the return movement of the arm. The disc 39 is stopped when the end of the recess 45 contacts with the pawl 44, thus determining the position to which the shroud 33 is returned. Variation of feed is obtained by adjusting the handle 41.

Title: Improvements in or relating to electrical resistors
IPC: H01C7/00
Filed: 1955-12-09
Abstract: In the production of an electrical resistor, an insulating body is given an oxide coating by depositing under oxidizing conditions a fluid medium comprising a volatile or steam volatile tin compound and compounds of antimony and boron in a furnace at 500 DEG  to 1000 DEG C.  As described, a vitreous or ceramic body, e.g. porcelain, may be roughened by sand-blasting before being cleaned by immersion for one week in chromic acid which may be heated. The coating is applied by a vapour deposition or spraying stannic chloride, antimony trichloride and boric acid dissolved in hydrochloric acid in a furnace using an acid-resisting atomizing gun intermittently to minimize cooling. These compounds decompose in the presence of oxygen and water vapour to form the required oxides.  One or more oxides of titanium, aluminium, barium, magnesium, silicon, zinc, manganese or cobalt may also be included.  Tables giving changes in the ratio of the compounds in the coating medium expressed as oxides before and after application are given.  It is stated that the coatings 100 to 10,000 Angstrom units thick should be protected by a moisture-proof lacquer.
