Abstract: Butadiene is polymerized using hydrogen peroxide as a catalyst to provide polybutadiene (partaking of the nature of a polymethylenediol) suitable for use in making polyurethanes by reaction with diisocyanate compounds. Minor amounts of vinyl cyclohexene and related odiferous impurities are contaminants in such polybutadiene. Such contaminants are predominantly removed by selective volatilization during one or more treatments in a hot vacuum zone, the feedstock to the hot vacuum zone containing from about 0.4 to about 6 % of a C 9 -C 13  saturated hydrocarbon entraining agent.

Title: Method and apparatus for closing a thin-walled hollow can body
Inventor: ROWLAND WILLIAM GEORGE
IPC: B65B7/16
Filed: 1980-06-25
Abstract: Athin-walled can body having a terminal curled rim at an open end thereof, has this open end closed and sealed by a diaphragm which is first formed into a dished shape by a forming tool which then cuts the dished diaphragm from a web and places it on the open end of the body. The upturned edge portion of the diaphragm is subsequently pressed into adhesion between a heat-sealable layer of the diaphragm and the curled rim, the latter being hot, by a presser tool (74) comprising a mount (78) carrying a spring-loaded pad (82). The pad is resiliently deformable and applies controlled pressure directly on the diaphragm, thus effecting complete conformity of the latter to any irregularities of the curled rim.

Abstract: Apparatus for illuminating a narrow transverse strip on a document (15), includes a pair of laterally extending illumination lamps (43) and a pair of trough shaped reflectors (42) for collecting light from the illumination lamps and focussing one-dimensional images of the lamp filaments along a common line extending across the document. Each trough shaped reflector (42) has an associated flat reflecting mirror (45) for directing its beam of illuminating light towards the document. The two flat mirrors (45) are rotated in synchronism for scanning the light beams longitudinally along the document. The trough shaped reflectors are moved in synchronism with the scanning movement of the beams so that the images of the lamp filaments remain in one-dimensional focus throughout scanning of the flat document plane. The illuminating light is further collected and directed toward the document by a pair of reflective side surfaces which define walls for the illumination station.

Zur platzsparenden Einplanung in eine mehrsträngige Anläge sind die Stützrollen 12 in Schwenkrahmen 13 gelagert, welche von senkrecht hochgestellten Zylindern 34 verstellt werden. Damit die Stützrollen 12 an unterschiedliche Strangabmessungen anpaßbar sind, werden sie innerhalb der gabelförmigen Schwenkrahmen 13 von vertikal beweglichen Führungsrahmen 14 mit darin eingesetzten horizontal verstellbaren Rollenträgern 15 aufgenommen.
