Title: Dispersion enhanced pt group metal catalysts
Inventor: SUBRAMANIAN SOMASUNDARAM
IPC: B01J23/40
Filed: 1991-08-30
Abstract: Abstract of the Disclosure A method of making a three-way catalyst based on platinum group metals, comprising: (a) impregnating an alumina substrate with a platinum group metal ion by contacting such substrate with an aqueous solution containing the platinum group metal in an amount of 0.1-5% by weight of alumina substrate and a water soluble acid that forms RCOOH with R being an alkyl or equivalent, said acid being present in an amount of 10-120% by weight of the alumina substrate, the pH of said solution being less than 4.0; and (b) drying and calcining the wetted substrate without sintering said substrate.         The three-way catalyst construction based on platinum group metals has enhanced catalytic activity. It comprises an alumina substrate and a platinum group metal impregnation layer thereover, said impregnation layer being comprised of raft-like particle structures, each having increased metal density resulting from the nesting of both small and large metal particles within a given volume.

Patent CA-2053819-A1 (CA)
Inventor: YOUNG DOUGLAS L G
IPC: B03B5/00
Filed: 1991-10-21
Abstract: A screening apparatus (20) removes a fluid borne pulp fibre slurry from knots which have been concentrated from a pulp processing stream. A rotating radially symmetrical screen (30) provides centrifugal screening to accept a pulp fibre slurry while an integrally connected spiral flight conveyor (17) transports knots from the inner surface of the screen to a knot discharge chamber (34) located axially above the screening chamber (62). Above the screening chamber but below the liquid level (65) in the housing (14), a fibre free wash liquid is provided through a tangentially orientated nozzle (32) in the direction of rotation of the spiral flight conveyor to release fibres from the knot surfaces thereby enabling them to pass through the screen. The screening apparatus also provides for removal of heavy tramp materials, for maintaining liquid level control, for minimizing air entrainment and foam formation, and for preventing clogging of the screen apertures and knot discharge outlet. <IMAGE>

Abstract: The process for detection and masking of bad frames in a coded speech signal resulting from channel transmission errors has been improved.  The coded speech signal has a first group of bits comprising the most perceptually significant bits of the coded speech signal, a second group of bits comprising the second most perceptually significant bits and a third group of bits comprising the least perceptually significant bits.  The coded speech signal is de-interleaved to obtain a first series of bits comprising the first and second group and a second series of bits comprising the third group of bits. The first series of bits are convolutionally decoded for recovering the first and second group of bits, with the first group of bits containing error protected bits.  A CRC check is performed by sending the recovered bits of the first group to cyclic redundancy decoding means.  The first group of bits is forwarded to speech decoder means if the CRC check is successful.  The frame energy and LPC parameters are replicated for the first and third group of bits and the frame energy, LPC parameters, lag value and sub-frame gain are replicated for the second group of bits, and subsequently the replicated bits are forwarded to the speech coder means, if the CRC check is not successful.
