Title: Method and device for writing optical record carriers
Inventor: DUCHATEAU JOHAN P W B
IPC: G11B7/126
Filed: 1998-12-03
Abstract: A method is described for optimizing recording conditions for writing information on an optical record carrier. The information is written on the record carrier in the form of optically detectable marks, each mark being written by a pulse series of radiation. A series of test patterns is written on the record carrier (1) for the optimization. A  jitter detector (11) measures both the leading-edge and trailing-edge jitter of the read signal. The leading-edge jitter is used to optimize the value of a parameter influencing only the leading part of a pulse series. The trailing-edge jitter is used to optimize a parameter influencing only the trailing part of the pulse series.

Title: Method and apparatus for separating fast settling particles from slow settling particles
Inventor: COLLEGE JOHN W
IPC: B01D21/26
Filed: 1999-10-26
Abstract: A hydroseparator for separating particles based on the differences in settling rates such as for separating fly ash from gypsum includes a substantially cylindrical side wall closed at its bottom end by a floor. A laminar upflow is created through the hydroseparator by adding dilution water to the bottom of the hydroseparator and removing most of the added dilution water from the top of the hydroseparator. The remaining volume of liquid is removed in an underflow. The hydroseparator is divided into at least two sections by a baffle that extends about the interior of the side wall. An inlet is disposed in the center of the hydroseparator slightly above the baffle such that the material added to the hydroseparator to be separated is inserted into the section of the hydroseparator completely surrounded by the baffle. The velocity of the upflow is controlled such that it is not fast enough to cause the faster-settling gypsum particles to rise but is fast enough to cause the slower-settling fly ash particles to rise with the upflow. The upflow thus separates the fly ash from the gypsum and floats the fly ash to the top of the hydroseparator where it is removed in the overflow. An agitator is provided in the lower portion of the hydroseparator to evenly distribute wash water and to keep the gypsum fluid.

Patent CA-2307834-A1 (CA)
Inventor: FLEURY JOCELYN
IPC: H02G1/04
Filed: 1998-11-13
Abstract: The cable support block has an arcuate frame having two spaced-apart legs defining an opening therebetween with an elongated coil spring bridging the opening in its unstressed, closed position, the coil spring being attached at its first end to a single one of the frame legs. The upper portion of the frame defines a yoke allowing the support block to rest on an upper cable spacedly supported over ground. The lower portion of the frame rotatably carries an idle roller on which a lower cable being installed or stringed can rest. To insert a cable into the arcuate frame, the cable is forcibly abutted against the coil spring which will resiliently yield to allow access into the arcuate frame by being inwardly deformed. A shoulder is located on the frame leg opposite the one where the coil spring is attached. The shoulder prevents accidental release of the cables trapped inside the arcuate frame by preventing outward displacement of the coil spring second end portion. The coil spring second end portion may alternately be resiliently moved around the shoulder, to allow outward deformation of the coil spring, so that the cables located inside the arcuate frame may be retrieved from therein. The support block is especially useful in combination with a telescopic pole, which allows distal handling of the support block from ground level for installation and removal thereof.
