Title: Mullite porcelain
IPC: C04B35/18
Filed: 1959-07-17
Abstract: A mullite porcelain is produced by calcining a mixture containing by weight 70% to 80% mullite grog, 20% to 30% ball clay and 0 to 10% kaolin; the mullite grog is 95% crystalline mullite containing 75% Al2O3 and 25% SiO2, the ball clay containing 28% to 31% Al2O3 and 53% to 56% SiO2 with less than 20% free SiO2 and a Seger Cone equivalent of 32 to 34, while the kaolin contains 36% to 38% Al2O3 and 46% to 48% SiO2 with less than 5% free SiO2 and a Seger Cone equivalent of 35 to 36.  The mullite grog which may contain 2% corundum and 3% glass is formed by calcining a mixture of low alkali content Al2O3 and kaolin clay between 3245 DEG F. and 3326 DEG F.  The ground mixture is cast, pressed or extruded, and for casting the ball clay should contain less than 10% illite and the kaolin should have 93% of its particles finer than 10 micron.

Title: Improvements in or relating to transistor amplifiers
Inventor: CLARK THOMAS HAROLD
IPC: H03F1/34
Filed: 1959-07-24
Abstract: 912,412. Transistor pulse amplifying circuits. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. July 25, 1960 [July 24, 1959], No. 25535/59. Class 40 (6). A pulse amplifier comprising a first transistor connected in common emitter mode, capacitively coupled to a second transistor, and a capacitive feedback path is arranged to inhibit momentarily the effect of input pulses if these exceed a predetermined length, and produce a fast interruption of the output pulse. A common emitter input state T4, has its collector clamped to a potential - 6 v. and coupled via a capacitor C7 to the base of transistor T10, the emitter of which is clamped to +50 v. The output from the amplifier is taken from the collector of a third transistor T11, the emittercollector path of which is connected in series with that of T10. In the cut-off condition, the collector potential of T11 is defined by the clamping diode D14 and resistors R15, R16, at - 25 v. Positive-going input pulses applied to the base of T4 switch this transistor off and feed a negative pulse via C7 to switch on T10 and hence T11, the potential at the output rising to +50 v. For normal length pulses (300 microseconds) the potential at the collector of T4 never reaches the clamping potential of - 6 v. and hence C7 continues to charge until T4 is switched on again by the trailing edge of the pulse. If the pulse is excessively long, the potential at T4 collector reaches - 6 v., the capacitor ceases to charge further, and the output pulse is rapidly terminated due to the positive feed-back over capacitor C17, the output waveform is thus chopped to prevent overheating. A number of amplifiers may be used in connection with storage devices described in Specification 803,881, the amplifier outputs being fed via diodes to a scanning arrangement of cold cathode tubes.
