Title: Electrical melting apparatus for glass
IPC: H05B3/62
Filed: 1975-08-27
Abstract: 1508820 Resistance heating element OWENSCORNING FIBERGLAS CORP 27 Aug 1975 35379/75 Heading H5H In electrical melting apparatus e.g. glass melting apparatus having a plurality of elongate parallel resistance heating elements 120 extending across the interior of a melting receptacle 122 provided with a discharge outlet 124 at its bottom, each elongate element 120 which has a width W (Fig. 5) greater than its thickness t (Fig. 6) is oriented with its width dimension W vertical and is provided with short end connector portions 146 connected by electrically parallel vertically spaced longer central portions 148. This parallel arrangement ensures that should the upper central potion 148 become cooler than the lower central portion 148, the resistance of the upper central portion 148 will decrease so that more current will flow along Path I than Path II and the temperature of the upper central portion 148 will increase. Similar compensation will occur if the lower central portion 148 becomes cooler than the upper central portion. As shown each element 120 is made of platinum or a platinum alloy containing rhodium. The elements 120 are made tubular and are reinforced in the elliptical central region 144 by tubular refractory cores 158 of good heat conductivity material e.g. aluminium oxide and in the connector portions 146 by solid refractory heat conducting aluminium oxide. The aluminium oxide cores assist in equalizing the heat distribution and consequently heat generation. The end connectors 146 are curved tubes, as shown, with additional metal strips 152, 154 secured to the top and bottom of the portions 146a and 146b of the connectors 146. The improved conductive path provided by strips 152, 154 assists in the uniform division of current to the upper and lower paths I and II. The end connectors 146 of the elements 120 are clamped between water-cooled bus bars 160, 162 extending lengthwise of the melting receptacle 120. The bus bars 160, 162 are connected to stepdown transformers. A control circuit senses voltage variations caused by changes in resistance of the heating element and modifies the supply current to restore the temperature to the elements 120. An alternative form of element (Figs. 10 and 11, not shown) comprises a straight tube to which is attached a parallel tube by two inclined portions. The ends of the straight tube form the connectors. Instead of the elements 120 being arranged with dimension W vertical as in Fig. 3, they may be slightly inclined, the inclinations being in opposite directions relative to the central longitudinal plane of the receptacle. The angle of inclination to the vertical decreases from the central plane. The molten glass emerging through the outlet 124 in filaments 20 is further heated to control its viscosity by the platinum walls 272, 274, 270 lining the outlet 124 which are supplied from a transformer via terminals 286.

Title: Method of heat treating a material
IPC: C30B13/16
Filed: 1972-07-28
Abstract: 1382353 Crystallizing from a melt; zone melting PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 28 July 1972 [31 July 1971] 35393/72 Heading B1S [Also in Division F4] Crystals including monocrystals are made by passing a temperature gradient through a melt in a vessel e.g. a crucible, located in a chamber the walls of which are heat-transmitting and surrounded by a container spaced from the chamber, the said temperature gradient being formed by establishing an interface between vapourized heat transfer medium and a gas inert to the medium. The surrounding container which is insulated contains a heattransmitting wall through which heat is passed to vapourize a heat-transfer medium contained in the space between the chamber and the crucible. The movement of the interface is controlled by increasing or decreasing the amount of heat supplied to the transfer medium. The transfer medium may be potassium, sodium, lithium, cadmium, caesium, an alloy or an organic compound e.g. a hydrocarbon. The inert gas may be argon, nitrogen, neon, helium or air under normal atmospheric pressure provided it is not reactive with the medium. The inert gas is always at constant pressure. If desired, in the space between the chamber and container, a porous mass having a capillary structure may be present connecting the heat transmission walls of the chamber and container. The porous mass may be compressed steel wool, wire gauze, or a network of glass fibres. As shown, a tubular treatment chamber 1 is bounded by a heat transmission wall 2, of container 3. The latter contains a heat transmission wall 4 through which thermal energy from heating coil 5 is supplied to the container. The power supplied to coil 5 is controlled by device 6. The container 3, insulated from the surroundings by layer 7, comprises a gas buffer space 8 in communication with gas storage container 9 containing a control valve 11. The container 3, contains the medium e.g. sodium, and in operation the location of the interface 10, is determined by the power of the heating coil 5. The material to be crystal-. lized is contained in vessel 12, suspended from a frame 13. In modifications, the container may have its longitudinal axis horizontal and space 8, as the flow back of the medium is not under gravity, filled with a porous mass preferably compressed steel wool. Also two chambers may be present in the container (Figure 6 not shown). The apparatus may also be used for zone-melting purification.

Convention date, Dec. 31, 1931. [Class 57.] A centrifugal switch particularly for controlling an auxiliary winding of a single phase motor, comprises a member 30 mounted to rotate with the motor shaft 15 and provided with a series of radial grooves in each of which is situated a metal ball 35 adapted to fly out when the motor is running and engage the sloping surface 43 of a cam-plate 41. This moves a floating insulating disc 38 to the right causing the circuit to be broken between a metal ring 39 and contact strips 50. When the motor.slows down, contact is remade due to a spring 46. As circuit is being broken, friction between the contacts becomes less and the ring 39 starts to rotate thus cleaning the contact surfaces. After contact is broken the disc 38 and camplate 41 rotate with the member 30. A similar cleaning action takes place at the' moment of making contact.
