Abstract: 1385268 Protective atmospheres for float glass apparatus VETRERIA DI VERNANTE SpA 14 June 1972 [14 June 1971] 27851/72 Heading C1M To prevent oxidation of molten metal by providing a protective environment in a zone of apparatus for producing float glass ribbon, a gaseous mixture comprising nitrogen and hydrogen is passed through a reaction chamber containing a mixture of materials corresponding to the carbon-bearing degradable components of the zone, the materials being mixed in proportions corresponding to the proportions of the same materials in the components of the zone and maintained at a substantially corresponding temperature so as to obtain a reacted gaseous mixture which does not effect degradation of the components of the zone, the reacted gaseous mixture then being supplied to that zone. The original gaseous mixture is N 2  95% and H 2  5% by weight and one or more hydrocarbons, particularly propane can be added, the propane being for 0À5 to 4% by weight of the gaseous mixture. The materials mixture includes graphite, silicon carbide and boron nitride and the proportion referred to is 100 : 5 : 1 respectively. The temperature is maintained at about 900‹ C. Specification 1,228,157 is referred to.

Filed: 1925-11-10
Abstract: 264,621. King, A. J., and Metropolitan- Vickers Electrical Co., Ltd. Nov. 10, 1925. Thermionic generators and modulators; order telegraphs.-Meter readings, are transmitted to a distant station by arranging the movable member to control the frequency of a current which modulates a carrier wave, the receiving apparatus comprising a frequency indicator. As shown in Fig. 1, the pointer 19 whose position is to be indicated at a distance, is connected to a variable condenser, or variable inductance, so that its movement varies the frequency of a tuned circuit 11, 23, 13 which determines the oscillation frequency of a back-coupled valve 15. The condenser 23 serves for the initial adjustment of the frequency range of the circuit. The oscillations are applied to the grid circuit of a modulating-valve 27 which is associated with the carrier wave generator 31 according to the choke modulation method. The modulated oscillations are transmitted to a line through condensers 49, 51 and are received in the detector valve 73, Fig. 2. The rectified currents are passed through a chain of amplifiers 85, 95, 105, the last valve having a frequency metor 107 of the tuned-reed type in its plate circuit. The amplifiers may be resistance-coupled, or as shown may be coupled by transformers broadly tuned to the band of frequencies employed. The separate modulating- valve 27 may be omitted, the choke 29 being connected in the plate supply circuits of both the oscillating valves 15, 31. In a further modification shown in Fig. 3, a single valve 120 generates both the carrier and the modulating wave. The circuit 126, 132 tuned to the carrier is connected in series in the plate circuit with the circuit 127 - - 129 tuned to the modulating frequency. Both circuits are back-coupled to coils 122, 123 in the grid circuit, a by-pass condenser 125 being connected across the coil 123. The varying condenser 129 is insulated from the high-tension supply by condensers 130, 131. According to the Provisional Specification, the system may be employed for signalling the position of apparatus other than meters.

Abstract: 690,194. Mops. HOMBERGER, V. Nov. 21, 1950 [Nov. 29, 1949], No. 28431/50. Class 19. An appliance for washing walls or the like includes a wringing roller adjacent to an absorbent roller and is furnished with means for rotating the wringing roller at will and locking it against rotation; the wringing roller when rotated compressing the absorbent material of the absorbent roller radially. The absorbent roller comprises an axial core upon which is mounted a cylindrical absorbent sleeve, the absorbent roller and wringing roller being mounted in a common stirrup for rotation about parallel axes which are separated by a distance less than the sum of the radii of the absorbent roller. The core. of the absorbent roller may be hollow and provided with perforations so that liquid may pass from the absorbent sleeve into the core and drain through a passage provided at one or both ends of the core. Preferably the absorbent roller is detachably mounted in the stirrup and is furnished at both ends with trunnions engaging in parallel arms on the stirrup. The wring- ing roller is preferably furnished at one end with a crank handle by which the roller may be rotated or the wringing roller may be adapted to be rotated by means of an electric motor. The stirrup may be furnished with a socket provided with a multi-start tapered screw thread in which to receive a correspondingly tapered screw-threaded end of the shaft. In the Figures a U-shaped stirrup 1 has parallel arms 7 and 8 and a socket 5 provided with screw thread 5<SP>1</SP> to receive the tapered and screw-threaded end of the shaft 2. Two rollers 3 and 4 are arranged with their axes parallel and in the same plane. The roller 3 has a core 9 upon which is forced a sponge sleeve 3' and is provided at its ends with metal trunnions 11 and 12 which engage in bearings in the arms 7 and 8. The bearing for the trunnion 11 is formed by one end of a bayonet slot 13. The roller 4 acts as a wringing roller for the absorbent roller 3, and is provided with a socket 4 and a trunnion 15. A crank handle 16 is screwed into the socket 14 of the wringing roller and is located outside the stirrup 1 and is furnished with a knob 17 which is carried by a yoke 19 pivoted to the outer end of the crank. The knob 17 and its yoke 19 are adapted to be stowed when not in use by being turned through an angle of about 180 degrees. In this position the yoke is adapted to engage the free end of a lug 18 formed integrally on the stirrup 1 so as to lock the crank and the roller 4 against rotation. This also locks the roller 3 which is of greater diameter than roller 4.
