Title: Process and apparatus for vacuum purification of the float glass bath
IPC: C03B18/18
Filed: 1967-10-09
Abstract: <PICT:1123384/C1/1> <PICT:1123384/C1/2> In a process for the manufacture of flat glass during which glass is advanced along a bath of molten metal, contaminants in the molten metal are removed by circulating the molten metal through a purifying zone, exposing the molten metal to a vacuum in that zone so that the impurities volatilize from the molten metal, collecting the impurities, and returning the purified molten metal to the bath. In one embodiment (Figs. 1 and 2) the molten metal is raised from a recess in the bath 1, the recess being defined by side walls 7, end wall 8, and a floor 9 which is a continuation of the floor 3 of the bath. The pocket of molten metal in the recess is divided into two parts 12 and 13 by a partition 11, and the two parts of the pocket communicate with the main part of the bath through channels 14 and 15. A vacuum tower is supported above the recess on a support frame 17, and has two hollow legs 18 and 19 which dip into the two parts 12 and 13 of the recess, and which communicate with an upper chamber 20 which defines the purifying zone. A bore 22 extends through the leg 18 and a similar bore 23 through leg 19. A branch pipe 29 has a bore 32 which communicates with the bore 22 and allows a non-oxidizing gas to be fed into the bore 22 and up the leg 18. The purifying zone 20 is connected by a pipe 40 to a condenser 43 and a vacuum pump 49. Operation of the vacuum pump causes a reduction in pressure in the chamber 20 resulting in molten metal filling the legs 18 and 19, and the introduction of the non-oxidizing gas through the branch pipe 29 induces a circulation of molten metal from the part 12 of the pocket of molten metal in the recess, up the leg 18 and into the chamber 20, and then down leg 19 and into the part 13 of the pocket of molten metal, the volatile tin oxide and/or tin sulphide being removed from the chamber 20 through the outlet 36 and pipe 40 to be collected in the condenser 43. The purifying zone and hollow legs of the vacuum chamber may be made of steel and may have carbon linings. The molten metal contained in the recess may be contacted by an element with which oxygen and/or sulphur preferentially reacts to form oxides and or sulphides which are readily released from the molten metal in the purifying zone. Phosphorus and carbon are specified.

Title: Hermetically-Sealed Motion Transfer Unit
IPC: G21C13/02
Filed: 1968-12-11
Abstract: A sealed plug for taking a rotary drive through the wall 3 of a pressure vessel is secured in position by a series of radially movable sectorshaped bolts 57 engaging under shoulders 61 on the vessel wall and moved by means of a wormgear 53. Pins 55 standing up from the sectors are constrained by radial slots 69 in collar 63 to radial motion only, but are moved by oblique cam-slots 67 in the worm-driven wheel 51. The plug and shaft are sealed in a conventional manner, except that a seal 39 beneath the plughead is axially compressed on outward movement of the sectors under the shoulders 61. As shown in Fig. 1 the motor-drive to the shaft has been replaced by a lifting cap 77. It is described how a sealed bell (Fig. 3, not shown) may be used to replace the drive unit without reduction of pressure in the vessel.

Patent ES-372912-A1 (ES)
Title: Magnetic reed proximity detector
IPC: B61L1/08
Filed: 1969-10-27
Abstract: A magnetic proximity detector has a polarized reed relay arranged so that flux is diverted due to the approach of a magnetic mass to permit contact operation to effect energization of the relay coil to reset the contacts so that the coil is de-energized. So long as the magnetic mass is in the vicinity of the relay its contacts will continue to open and close. As shown the encapsulated relay 5, which may be mounted on an insulating support 22 on a rail for operation by a railway wheel flange, has a sealed reed contact unit 7 surrounded by the coil 6 and spaced a set distance from a permanent magnet PM. The flux from the permanent magnet is insufficient for contact closure but sufficient to hold the contacts closed and on approach of a magnetic mass such as a wheel flange the contacts open to de-energize a relay A which has contacts sets 10, 11. When relay A is deenergized its contacts 10 close to energize the coil 6 which recloses contacts 7 to de-energize relay A to open contacts 10 which disconnect the coil 6 so that contacts 7 reopen if the magnetic mass is still present and so the relay A is continuously opened and closed until the mass is moved away. The contacts 11 operate when relay A is de-energized and disconnect a relay B which will not reset whilst the relay A oscillates since a capacitor 17 does not recharge sufficiently during the intermittent reclosures of contacts 11. A set of contacts 14 of the relay B connect the supply to the coil 6 through a resistor 15 so that the distance from the switch 5 at which the magnetic mass effects initial operation thereof is reduced.
