Patent CA-1294082-C (CA)
Title: Adaptive expander for telephones
Inventor: MEANS DONALD R
IPC: H04M9/08
Filed: 1988-11-07
Granted: 1992-01-07
Abstract: Abstract An adaptive expander for telephones reduces the gain of a transmitting amplifier in proportion to the intensity of the background noise. Gain reduction occurs when the user is not speaking into the handset microphone. When the user is speaking, however, the gain of the transmitting amplifier is restored to its normal level. Noise is distinguished from speech via long-term averaging of the microphone output signal, and a circuit that precludes the magnitude of the long-term average voltage from ever exceeding the short-term average voltage. The present invention is used in full duplex arrangements where simultaneous transmission in both directions is possible rather than in half duplex arrangements, such as a speakerphone, where transmission occurs only in one direction at a time.

Abstract: The invention relates to a method and to an arrangement for controlling the respective conduction times of two directionally opposed electrical devices (9, 10) which are mutually connected in parallel and permit current to pass therethrough solely in one direction, and which also permit current (l<sub>2</sub>) to pass through the primary winding (2) of a transformer during a respective half-period of an A.C. voltage (U,) applied to the primary winding, this control being effected so that the magnetizing current through the transformer can be advantageously minimized and/or held beneath a given limit value when an asymmetric load (4, 5) is applied to the secondary side (3) of the transformer. A magnetizing current in the primary winding corresponding to the load (5) of the secondary winding (3) is controlled through the agency of different conduction times of the two directionally opposed devices (9, 10).

Abstract: In a deinking process for a fibre stock or slurry air is introduced into the slurry so that air bubbles and ink come into contact, and the ink-laden bubbles are then separated from the slurry. 
<??>In order to provide an improved separation process the invention proposes to independently control the air injection, the mixing of the air and slurry, and the separation process by splitting them into separate steps so as to optimise the separation process. 
<??>Thus, there is provided a separation cell (31) which is fed with slurry from an inlet, an air inlet device, which in one embodiment comprises a porous sintered sleeve (7) to which air pressure is applied, and a mixing section which imposes turbulent flow on the air bubbles and slurry by passing the constituents through a series of turbulence discs (39). The resulting mixture enters the separation cell where the ink-laden bubbles rise to the surface as a foam which is conveniently removed by suction. The reinked slurry being drawn off from the separation cell.
