Title: Improvements in process for producing high density refractory bodies
IPC: C04B35/632
Filed: 1960-01-18
Abstract: High density sintered refractory bodies are formed from a mixture of the refractory powder and a binder such as refrigerated paraffin wax, the refractory powder containing less than 4% of particles larger than 2,5m  and with the ratio of the number of 0,1-0,8m  particles to the number of 0,8-2,5m  particles at least 3.  The refractory powder consists of the oxides, silicides, nitrides, carbides or borides of U, Pu, Th, Ti, W, Zr, Hf, Gd, Sm, Eu, Er, Dy, Ta, Nb, Mo, V and Be and 0,25% of Fe, Ni or Co metal powder may be incorporated in the mixture.  The formation of uranium dioxide bodies is exemplified, the oxygen/uranium ratio, initially 2,1, for example, being reduced to 2,0.  Sintering removes impurities, particularly F, B, Cu, Ni and Cr. Thus the refractory powder is first ball milled in acetone or in the dry state to the required particle size range and then blended with 0,5% to 10% by weight of refrigerated paraffin wax flour.  The mixture is milled above the melting point of the wax (130 DEG F.), screened at this temperature to form spherical granules which are then compacted to between 54% and 64% of the theoretical sintered density.  Sintering is effected at 2200 DEG /3550 DEG F. in an oxygen free atmosphere to produce a sintered body having a density between 94% and 100 of theoretical.ALSO:High density sintered refractary bodies are formed from a mixture of the refractory powder and a binder such as refrigerated paraffin-wax, the refractory powder containing less than 4% of particles larger than 2.5 micron and the ratio of the number of 0.1-0.8 micron particles to the number of 0.8-2.5 micron particles is at least 3.

In the embodiment, a speed reference signal as Fig. 3 is formed by charging a capacitor in a signal generator. With a 'O' (start) signal at the generator input M, the reference increases from A to B and limits from B to C due to a Zener diode across the capacitor. With a '1' (stop) signal at M, the reference falls from C to D, which is set by a limit circuit (6) Fig. 2 (not shown). The speed reference from generator 3, 4, 5 is compared in comparator 8 (which includes an operational amplifier) with an actual motor speed signal i.e. the voltage across resistor Rs in series with the motor 1. The output of comparator 8 is used to regulate the motor speed, by varying the rotor current, using complementary transistors 64, 65. The motor may drive a high speed magnetic tape. Details of the circuits are given in Fig. 2 (no shown).
