Title: Improvements in the manufacture of refractory articles
IPC: C04B35/64
Filed: 1936-05-15
Abstract: Refractory articles are made by adding low melting-point glass to silica-alumina base materials, e.g. kaolin, and heating to the melting-point of the glass and progressively higher.  The glass combines with an element or elements of the base material to form a succession of glasses of progressively higher melting-points, and the heating is continued until substantially all the glass has combined. Low melting-point glasses are those melting well below 985 DEG  C. preferably at about 815 DEG  C.  Preferably a boro-silicate glass, having a melting-point of 815 DEG  C., formed by the fusion of 144 parts of lime, 55 parts of feldspar, 49 parts of sodium carbonate, 925 parts of borax and 18 parts of silica is employed. Soda-lime glass and lead glass are also suitable.  In an example, 4 parts of powdered boro-silicate glass, M.P. 815 DEG  C., are mixed with 96 parts of raw kaolin to form a bond mixture.  30 parts of this bond are mixed with 70 of kaolin grog, i.e. kaolin which has been heated to about 1700 DEG  C. and crushed.  Bricks formed from the mixture are fired to a temperature of about 1235 DEG  C. and are held there for about an hour.  Porous bricks may be made, e.g. by aerating the mixture or by adding a fusible, volatile or combustible material such as wood flour or sawdust.  The hardness may be increased and the tendency to shrink reduced by adding 2-4 per cent of phosphate rock and 5-10 per cent of cyanite to the mass.

Abstract: 593,066. Protective cut out systems. QUINCEY, S. A. June 9, 1945, No. 14661. [Class 38 (v)] A system for protecting polyphase apparatus, e.g. a motor, against (1) singlephasing, (2) unbalanced three-phase conditions, (3) excessive temperature rise of the apparatus windings, (4) earth fault on the windings, (5) short-circuit between the terminals and (6) a reversal of phasesequence, comprises an air-gap transformer 3 connected to a condenser 1 shunted by a variable resistance 2, a thermo-sensitive element 18 in intimate thermal relationship with the apparatus windings, and a safety earthing connection for the apparatus framework. With fault (3) above, the element 18, which in this case is a high negative or positive temperature coefficient resistance, becomes heated and its resistance changes thereby unbalancing the circuit 1, 2, 3 and causing a voltage to energise a relay 12. This de-energises relay 13 and main-contactor winding 7 and opens the main contactor 6. Three star-connected condensers 24 are also provided and any voltage displacement between their neutral point and the neutral N of the supply system energises a relay 15 to open the circuit of relay coil 13 and hence contactor 6. To deal with a discontinuous earth wire or an earth fault accompanied by a high earthelectrode resistance, a transformer 4 constantly injects a small circulating current into the normal earth circuit 21, 23, which includes connections to the motor and starter frames and relay coil 13, rectifier 9 and earth electrode 20. If the earth circuit breaks, relay 13 is de-energised and contacts 6 open, whereas if an earth-fault occurs, with a high resistance at the main earth 21, a relay 14 connected to a rectifier 10 in a circuit between the earthing electrodes 20, 21, and including the frameconnections 23, is sufficiently energised to open the main control circuit including relay coil 13. A condenser 5 ensures operation of relay 12 if a blown fuse, or other fault, occurs in the supply line L<2>.
