Abstract: Alumina hydrate is prepared by adding an aqueous solution of an aluminium salt which is substantially free of metals other than aluminium to a substantially metal-free aqueous solution of ammonium bicarbonate, maintaining the resulting mixture at a pH between 7 and 9 throughout substantially the entire procedure and substantially preventing any pH in the mixture below 7 or above 9, and precipitating alumina hydrate.  The alumina hydrate has approximate formula Al2O3.1.2-2.6H2O and is 80 to 95% crystalline with an approximately cubic configuration, the unit cell being 8.2 <\>rA on edge.  The aluminium salt used may be AlCl3, Al(NO3)3, (HCO2)3Al or (CH3CH2CO2)3Al.

Abstract: 1477413 Echo suppressors COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 9 Dec 1974 [10 Dec 1973 15 Nov 1974] 53225/74 Heading H4R In an echo suppressor the insertion of a blocking element, 5, in the transmit channel 2 and the control of loss in an attenuator, 8, in the receive channel, 3, is effected by a logic unit, 10, in response to the level of signals observed upstream of the blocking element in the transmit channel and downstream of the attenuator in the receive channel, and the signal level in the transmit direction is observed in a transmit speech detector, 6, having two modes of operation, one mode in which a speech indicating signal is supplied based on the characteristics of amplitude and change in sign of the signal on the transmit channel and the other mode, effective when the receive channel is active, produces a speech indicating signal in response to a comparison of the amplitudes in the transmit and receive channels. As described the transmit channel detector 6 takes the signal at the input of a 20 mSec. delay line 4 and in its first mode determines the presence or absence of speech in dependence on the amplitude and zero crossings of the transmit signal while the receive channel signal is monitored by a fixed threshold detector 9, having a - 31 dBmo threshold and a 50 mS hangover time, and the logic unit 10 controls insertion of blocking unit 5 and attenuator 8 accordingly. The second operating mode of detector 6 can be brought into operation whenever the detector 9 recognizes a receive signal or, in an alternative embodiment, only when the detector 9 recognizes a signal and there is no signal at that time on the transmit channel. In the second mode of operation the detector 6 produces an output signal only when the transmit speech level is above a variable threshold set by the peak detector 7 in dependence on the peak level of the received signal. The operating states of the suppressor are: (1) Rest both channels inactive, speech detector 6 in its first mode, both attenuator 8 and blocking element 5 out of circuit. (2) Far talk receive channel only active, speech detector 6 in its second mode, attenuator 8 out of circuit blocking element 5 in circuit. (3) Near talk transmit channel only active, speech detector 6 in its first mode, attenuator 8 in circuit, blocking element 5 out of circuit. The first embodiment switches detector 6 to its second mode whenever there is a signal in the receive channel, while in the second embodiment the detector 6 remains in its first mode during double talk after a period of near talk and only switches to the second mode when only the receive channel is active.
