Patent CA-2062957-A1 (CA)
IPC: B01D33/09
Filed: 1990-06-26
Abstract: 2062957 9100768 PCTABS00003 The present invention relates to a method and apparatus for treating pulp, which method and apparatus are especially suitable for treating fiber suspensions in wood processing industry. The method and apparatus are particularly designed for thickening said suspensions, in other words filtering liquids from fiber suspensions in pulp and paper industry. The invention relates more closely to a so called drum cylinder, the basic construction of which comprises a vessel, into which suspension being thickened is supplied and a wire-surfaced cylinder rotating in the vessel. The drum filter in accordance with the present invention is characterized in that the closing member (40) of the drum filter has a channel (70) for leading gas from the filtrate tubes (24) through the compartments of the distribution chamber (26) to the outside of the closing member (40). The method in accordance with the present invention is characterized in that the operation phase of the filter cylinder is divided into five stages separated from each other, in the first stage, when the cylinder descends into the vessel, air and the initial filtrate are discharged from the filtrate compartments and the formation of the pulp web on the wire surface begins; in the second stage filtrate is discharged with vacuum and the formation of the pulp web continues; in the third stage pulp web is dried by means of vacuum when said part of the web has risen with the cylinder from the vessel; in the fourth stage, a so called removal stage, pulp web is removed from the wire surface and discharged from the apparatus; and in the fifth stage, a so called washing stage, the wire surface is washed.

Title: Method and apparatus for measurement and imaging of tissue compressibility or compliance
Inventor: OPHIR JONATHAN
IPC: G01S15/89
Filed: 1990-11-16
Abstract: An improved ultrasonic pulse-echo method and apparatus that has particular application in making precision measurements of compressibility in any backscattering material, in particular organic tissue, is disclosed. The method employs a standard transducer or transducer containing device which is translated transaxially, thereby compressing or displacing a proximal region of a target body in small known increments. At each increment, a pulse is emitted and an echo sequence (A-line) is detected from regions within the target along the sonic travel path or beam of the transducer. Resulting time shifts in echo segments corresponding to features in the target provide relative and quantitative information concerning compressibility of the target.

Abstract: This laser beam detector system may comprise an array of photodetectors usable in conjunction with a laser employed to define an elevation or grade.   The detector array is utilized on an elongate device having a plurality of faces, with a plurality of detectors disposed in a consistently spaced arrangement on each of the faces.  The detectors of each face have a field of view different from the field of view of the detectors of the other faces, and each detector on each face of the array is disposed at the same height as a  corresponding detector  on  each  of  the  other  faces. Importantly, each group of detectors at the same height are electrically interconnected into a co-functioning group. Our novel arrangement is such that a laser beam incident on any detector of a co-functioning group is detected, with the position of the detector upon which the beam impinged being identified, and a readout indicative of that detector then provided.   Such readout is conveniently in the form of a plainly visible representative character.

Title: Self-Healing Drop and Insert Communication Network
Inventor: WEISSMANN EMANUEL
IPC: H04J3/14
Filed: 1993-05-18
Abstract: A self-healing drop/insert (D/I) communication method and network are provided.  The network comprises two end stations  and  a  chain  of  intermediate  D/I  multiplexer stations to which the two end stations are connected by two lines, so as to provide communication in both directions, East and West,  for multiple data and/or voice channels between any of the stations.  According to the invention, the end stations are collocated or located near one another and in the event of a break or failure in the network, they are interconnected to form one D/I multiplexer station, whereas the stations on each side of the break or failure become new end stations. The communication transmitted by the multiple data and/or voice channels is then redirected away from the point of break or failure, when it occurs, thereby  allowing  the  network  to  self-heal  and  remain operational after the break or failure.
