Abstract: A first structural unit includes a laser image-setting head, and a second structural unit includes a loading compartment to accommodate a cassette housing having a thermal transfer ribbon on spools having hubs. After a cassette is inserted in the loading compartment, the compartment is closed so that drive rollers engage the hubs without play. To produce a printing plate, the second structural unit is then brought over the first structural unit in the manner of a telescope by a moving device, and the thermal transfer ribbon is brought to the laser image-setting head.  The thermal transfer ribbon inserted into the loading compartment is guided by self-centering means so that it does not contact the cassette housing, and is positioned with respect to the plate cylinder by guide rollers. Wear-free and therefore fast ribbon guidance can be performed, and automation of the movement sequences of the thermal transfer ribbon can be achieved.

Abstract: The present invention is directed to methods for separating and recovering propane, propylene and heavier hydrocarbons, i.e., the C3+ hydrocarbons, from a gas feed (10), e.g., raw natural gas or a refinery or petroleum plant gas stream. These methods employ sequentially configured first (20) and second (73) distillation columns, e.g., a de-methanizer tower (20) followed by a de-ethanizer tower (73). A cooled gas feed condensate is separated in the first column into methane and a liquid phase comprising ethane and heavier hydrocarbons. The liquid phase is separated in the second column (73) into a gas phase (77) primarily comprising ethane and a second liquid phase primarily comprising the desired C3+ hydrocarbons. At least a portion of the second gas phase (45) is introduced into the first distillation column as an overhead reflux to improve the separation of C3+ hydrocarbons. The methods of the present invention permit separation and recovery of more than about 99 % of the C3+ hydrocarbons in the gas feed at higher operating pressures.

Title: Method of manufacturing an intracutaneous microneedle array
Inventor: SHERMAN FAIZ F
IPC: B29C51/08
Filed: 2000-06-07
Abstract: A microneedle array is manufactured using a mold preparation procedure that begins by placing an optical mask over a layer of PMMA  material, exposing the PMMA  material to x-rays, then developing using a photoresist process. The remaining PMMA material is then electroplated with metal. Once the metal has reached an appropriate thickness, it is detached to become a metal mold that is used in a microembossing procedure, in which the metal mold is pressed against a heated layer of plastic material. Once the mold is pressed down to its proper distance, the plastic material is cooled until solidified, and the mold is then detached, thereby leaving behind an array of microneedles. If the microneedles are hollow, then an additional procedure is used to create through-holes all the way through the underlying substrate material using laser optical means.
