Title: Improvements in glass-melting
IPC: C03B17/04
Filed: 1963-05-18
Abstract: A method of melting glass or quartz in a furnace having a base outlet 3 for the molten glass or quartz, comprises supplying heat to the melt surface from burners 9 directed substantially horizontally above the melt surface and disposing raw materials for the melt in a thin annular layer on the melt surface, the inner periphery of said layer encircling but not covering said molten glass outlet and the outer periphery of said layer being spaced from the inner wall of the furnace. The burners 9 are offset from the vertical axis of the furnace, Fig. 2 (not shown), and hence impart a whirling motion to the combustion product gases 45. The raw materials are charged from a shaking gutter 35 through a tube 38 into the furnace, the said tube being positioned in a gas outlet 13 coaxially disposed above the molten glass outlet. The rising, whirling combustion gases exert an expanding effect on the free-falling glass-forming particles which are finally deposited on the melt surface in a thin annular layer or zone 31, Fig. 2, having an inner periphery surrounding the melt surface 33 above the molten glass outlet and an outer periphery spaced from the furnace wall. The to-be-melted or melted particles in said annular layer follow the trajectories 35, 36 and 37, enter the drawing cone 15, and are discharged to the drawing machine 21. The drawing cone <PICT:1041825/C1/1> comprises parts of molybdenum and is provided with a mandrel 17 and a tungsten heating element 23. The cone and coil are contained in an envelope 25 to which a supply of non-oxidizing gas is connected. As shown at 27, non-oxidizing gas is supplied to the bore of the being-drawn tube. The diameter of the annular layer or zone of the raw material may be maintained constant with varying particle size by adjusting the height A of the movable tube 38 above the melt surface.

Title: Temperature protection circuit
IPC: H02H7/085
Filed: 1964-06-03
Abstract: A protective control system, e.g. for a motor 12, comprises a contactor 16 and a relay having contacts 32 in series with the contactor coil 20 and a coil 36 in series with a three-electrode device, e.g. a silicon controlled rectifier 38, having its control electrode connected to a bias circuit including a condition responsive impedance, e.g. a negative temperature coefficient resistor 28 in the motor winding 10. A positive feed-back circuit provides a large differential between, e.g. the temperature at which the motor supply is interrupted and the temperature at which the supply can be restored. In the arrangement shown, with the motor running under normal conditions, the rectifier fires on alternate half-cycles to maintain the relay coil 36 energized, the necessary bias being provided by a circuit through resistors 48, 28, 34. This bias is supplemented by the positive feed-back provided by the contactor coil current flowing through the resistor 34. When the winding temperature becomes excessive the resistance of the resistor 28 falls, causing a reduction in the bias so that the rectifier 38 ceases to fire. The consequent opening of the relay contacts 32 removes the positive feed-back, so that a considerable reduction in winding temperature to suitably increase the resistance of the resistor 28 is necessary before the rectifier can fire. Figs. 2 and 3 (not shown) illustrate arrangements in which further resistors provide a " voltage " positive feed-back in addition to the " current " feed-back.

Abstract: A cage 5 provided with a load platform 85 is raised on guides 3, 4 by reciprocation of pedals 11, 12 which are coupled to clamp blocks 27, 28, 47, 48 on the guides and cause the clamp blocks to move up the guides step by step. The clamp blocks comprise a wedge-shaped shoe 56 which is urged upwardly in a housing 53 by a spring 61, whereby downward movement of the block is prevented. A further shoe 63 is formed with a projection forming a piston in a chamber 65. The chambers of the upper pair of clamp blocks are interconnected via a pipeline 66a and those of the lower pair are interconnected via a pipeline 66b and communicate respectively with chambers 70a, 70b in a cylinder 71, on the cage 5. The size of the chambers 70a, 70b is varied by a hand lever 76, pivoted at 77 and engaging pistons 75a, 75b. During upward movement of the cage, with the lever 76 in its upper position, a maximum fluid pressure is exerted on the jaws, and reciprocation of the pedals 11, 12 moves the clamp blocks step by step up the guides by means of linkages, Fig. 1. On moving the hand lever 76 downwardly, the pressure exerted on the clamp blocks is reduced allowing the clamp blocks and the cage to move downwardly at a controlled speed.

Title: Method and apparatus for supporting sheet material
IPC: B65G51/03
Filed: 1968-07-09
Abstract: Articles, such as glass sheets, are supported, at least partially, by gas jets which discharge upwardly towards the articles from orifices which are displaced horizontally or with a horizontal component of motion. In the embodiment shown in plan view in Fig. 1, the upper run of an endless belt having transverse rows of slots 12 passes over the upper face of a plenum chamber 1 which is formed with longitudinal slots 7. In operation, the article is supported by gas jets passing through the orifices 14 formed by the intersection of slots 7, 12, the orifices moving at the same speed as the upper run of the belt. In a modification, Figs. 3, 4 (not shown), the endless belt is mounted within the plenum chamber, with the upper run of the belt adjacent the top wall of the chamber. For handling curved sheets, the top of the chamber is of arcuate cross-section and the belt rollers have curved generatrices. In a second embodiment, Fig. 6, the sheet 43 is supported partially by rollers 25 and partially by gas issuing from radial apertures 29 in hollow rollers 26 connected to a plenum chamber. In operation, the rollers 26 are rotated in the direction 42 corresponding to the required direction of movement 44 of the sheet 43. The driving effect of the gas jets can be modified by moving rollers in which the apertures are inclined to the radii or by deflecting the jets on one side of the rollers by vanes 109, or by masking the apertures on one side by screens 110. The sides of the sheet may be guided by edge rollers or belts (not shown). In a modification, Fig. 8 (not shown), additional blowing rollers are provided above the sheet. The apertures in the rollers may be arranged in one or more helical series around the roller axis, Figs. 10, 11 (not shown). For handling curved sheets, the lower rollers are barrel-shaped and the upper rollers are formed with a corresponding concave profile, Figs. 12-14 (not shown).
