Title: Improving the water resistance of articles containing fine vermiculite
Inventor: ATKINSON ALAN WILLIAM
IPC: C04B41/50
Filed: 1988-04-26
Abstract: Certain articles required to function in air at temperatures of 250 DEG C or higher comprise very fine particles of vermiculite from which the interstitial magnesium ions have been at least partially removed and which has been swollen in water. These articles are not ordinarily exposed to water when in use, but if they are they are likely to disintegrate quickly because of the ready dispersibility of the vermiculite particles. By the invention, water-resistance is given to such articles by treating them with a solution of an aluminate salt eg NaAlO2 or a zirconyl salt eg ZrOCl2.
Patent GB-882006-A (GB)
Abstract: 882,006. Frequency measurement. ROCHAR ELECTRONIQUE. April 11, 1960 [April 10, 1959], No. 12806/60. Class 37. [Also in Group XIX] A counter for use in frequency measurement adapted to count the numbers of pulses occurring in successive predetermined periods of time, has a display device comprising a plurality of glow discharge gaps, the transfer of the glow discharge taking place during short intervals of time separating the successive counting periods. As described, pulses to be counted arrive in intervals (0, t 1 ), (t 3 , t 4 ), &c.. Fig. 2, the intermediary intervals such as (t 1 , t 3 ) being split into two parts, the first (t 1 , t 2 ) being used for operat ing the display, and the second (t 2 , t 3 ) for resetting the counter. As shown in Fig. 5, pulses to be counted are applied to an input 16 of a decimal counter comprising four bi-stable double triode stages 12-15 and a diode 18. The outputs from the counter stages are applied through a decoding network to a display device 3 comprising ten thyratrons 6 and a gas indicator tube 5 adapted to display illuminated digits. Assuming that during the interval (0, t 1 ) nine pulses are applied to the input 16, the display device 3 registers during this period the value of the count during the previous counting period, Fig. 2 (b). At the instant t 1 , a negative pulse is applied to the anode of the indicator tube 5, thereby causing the total count of pulses during the period (0, t 1 ) to appear on the tube 5. A negative pulse applied to an input 17 is then effective to reset the counter. A circuit for providing the supply to the anode of the tube 5 of a normally steady potential interrupted by short negative pulses is described (Fig. 7, not shown). The counter and display device may comprise a number of decades similar to that shown. The indicator tube 5 may be omitted.
