Abstract: An echo canceller (20) with an adaptive convolution processor (50) for computing and subtracting an anticipated echo, in-cluding a nonlinear processor (82) which attenuates the error signal over a continuous range. A noise injection source (83) cou-pled to the send output variably injects an artificial noise signal in inverse proportion to error signal attenuation. The gradual ad-justment of error signal attenuation and maintenance of the output noise level at the average background noise level of the input, make operation of the echo canceller (20) unnoticeable to a far end listener.

Abstract: An empty/load changeover valve device for a railway car having a proportioning valve via which the car control valve supplies brake cylinder pressure.  The proportioning valve comprises a balance piston having equal opposing pressure areas and a combined supply and release check valve,  one pressure area of the balance piston being subject to air pressure supplied to the brake cylinder under all conditions of loading.   The opposing pressure area  of  the  balance  piston  is  either  pressurized  or depressurized depending upon the car being in an "empty" or "load"  condition,  thereby  establishing  either a  non-proportioning or a proportioning mode of brake control.          Integrating the release check valve with the supply valve so as to have a smaller effective pressure area,  the release check valve can be opened with low force to exhaust brake  cylinder pressure  during brake  release,  thereby making possible a reduced size empty/load changeover valve device.

Abstract: Docket METHOD AND COMPOSITIONS FOR MANUFACTURE                  OF CHEMICAL SENSORS                 ABSTRACT OF THE DISCLOSURE      The method for making an optical fiber microsensor involves applying an uncured analyte sensing matrix to an optical fiber and crosslinking the sensing matrix in situ on the optical fiber to yield an ion permeable microsensor which can be used intravascularly to monitor pH, or partial pressures of oxygen or carbon dioxide in blood.  The liquid form of the sensing matrix contains a crosslinking agent and a  crosslinking  inhibitor which  can  be  removed by exposure to elevated temperatures to allow the sensing matrix to crosslink and cure as desired, in situ, on the surface  of  the optical fiber. A liquid  crosslinking overcoat  layer  containing  a  crosslinking  agent  and a crosslinking inhibitor which can be removed by exposure to heat can also be applied over the cured sensing matrix.

Title: Method and device for separating a suspension, preferably a fibre suspension
Inventor: FJAELLSTROEM ROLAND
IPC: B01D33/58
Filed: 1993-01-28
Abstract: A suspension containing fine and coarse particles is sprayed under high pressure by means of spray nozzles (10) against a rotating filter medium (7), so that the suspension is separated into a fine fraction, which passes through the filter medium and which contains said fine particles, and a coarse fraction, which does not pass through the filter medium and which contains said coarse particles. According to the invention the filter medium (7) is rotated by means of a drive motor (6) at a speed such that coarse particles and liquid developing on said side of the filter medium are removed from the filter medium substantially as a result of the centrifugal force said coarse particles and liquid are subjected to by the rotating filter medium. In consequence the filter medium is efficiently kept clean during operation, which increases the capacity and improves the separation efficiency.
