Patent CA-2037862-A1 (CA)
Inventor: ROUNBEHLER DAVID P
IPC: G01N30/74
Filed: 1991-03-08
Abstract: Disclosed are a method and apparatus for high speed, selective detection of vapors of specific compounds, particularly nitrogen-containing compounds, utilizing a bypass branch and high speed gas chromatography for improved selectivity and sensitivity of detection. A system with two gas chromatographs (GC's) alternating in series with two pyrolyzers provides two time intervals of detection in a downstream detector, with the second time interval containing signals delayed and further separated relative to signals from the first time interval. The bypass branch, in diverting a portion of the flow of gas samples from passage through the second gas chromatograph and second pyrolyzer, avoids interferences in the first time interval of detection from non-GC-retained compounds decomposed in the second pyrolyzer.

Patent CA-2061228-A1 (CA)
Inventor: KOBAYASHI TADASHI
IPC: H02M3/335
Filed: 1992-02-14
Abstract: In a ringing choke converter, a series circuit of a capacitor means and a diode means is disposed between a base and an emitter of a switching transistor means, and a constant-voltage diode means is linked in parallel with the capacitor means. In consequence, a voltage applied to the capacitor means does not exceed a voltage value of the constant-voltage diode means. In particular, a collector surge current flowing through the switching transistor means is restricted by the voltage value of the constant-voltage diode means. Consequently, even if the switching transistor means abruptly changes its operation when the converter is switching on or off, it is possible to prevent an excessive surge current from flowing through the transistor means.

Abstract: An apparatus for the emptying of a plate press during the manufacture of laminated plates, the plate press having a lower press plate and an upper press plate, includes an arrangement for the picking-up of fully pressed laminated sheets at the discharge side of the opened plate press to form an entry mouth between the lower press plate and the laminated sheet, and a conveyor tray which is insertable into the entry mouth to thereby pick-up the laminated sheet, which is removable from the opened plate press while supported on the conveyor tray.  A suction lifter arrangement is provided at the discharge side of the plate press and includes suction lifters which are movable into the opened plate press and lowerable onto a fully pressed laminated sheet in the press.  The laminated sheet is lifted by way of the suction lifters to form the entry mouth.  A laminated sheet receiving table is positioned at the discharge side of the plate press and is hoistable or lowerable.  The conveyor tray while supporting a picked-up laminated sheet is movable over the laminated sheet receiving table and the laminated sheet is positioned onto the laminated sheet receiving table or onto laminated sheets already supported thereon by a reverse movement of the conveyor tray.  The suction lifters act on the surface of a fully pressed laminated sheet, but only in a peripheral region and only for a very short time so that disturbances of the surface structure of the sheet are substantially prevented.
