Patent CA-2099421-A1 (CA)
Title: Computer Network
Inventor: EVANS LAWRENCE S
IPC: G06F15/163
Filed: 1993-06-30
Abstract: Computers  are  linked  together  to  form  a  network. Messages are sent over the links between the computers in compressed, segmented form, the size of the segments being appropriate to the transmission characteristics of the link. A message previously received or transmitted by a computer is stored in compressed and segmented form. If it is desired to forward or re-transmit this message, the segment size of the stored form is compared against the optimum segment size for the link over which the message is to be sent. If there is a close match,  then the  stored segmented,  compressed message is retrieved for direct transmittal, without having to resegment or recompress the message.

Patent CA-2103688-A1 (CA)
Inventor: LERNER BERNARD
IPC: B65B51/30
Filed: 1993-08-06
Abstract: An improved packaging machine that has improved features for feeding a web in the form of a continuous chain of bags through the machine while helping maintain the web in proper alignment and proper tension, and having additional features for improved loading of the bags. The improved web feed includes a dancer assembly equipped with a pair of nips that are driven at speeds responsive to the rate of web travel through the machine so that tension between a web supply and, the dancer nips is isolated from the downstream portions of the web. A web feed mechanism which automatically threads the web through baggers is also provided. The web feed mechanism includes elastic belts which frictionally grip the web to isolate the tension in the section between the dancer nips and the belts from the tension of the web feed mechanism. Nips adjacent the load station and at the downstream end of the web feed mechanism have surface speeds exceeding the surface speed of the belts to maintain tension on the web through the web feed mechanism and effect a slight pre-opening of the bags before they are delivered to the load station. Other features include a cantilevered support of the web supply and bagger, a bagger support which functions as a plenum, an improved dancer assembly, and improved application of compressed air for bag opening.

Patent CA-2119816-A1 (CA)
Inventor: HOENES JOACHIM
IPC: G01N33/52
Filed: 1994-03-24
Abstract: A test strip analysis system consists of an analysis apparatus with a test strip holding means and matching test strips. The test strip holding means serves to position the test strip in a defined position relative to a measuring unit. It comprises a test strip seating means and a guide for the test strip. Exact positioning with simple handling and without sophisticated mechanical elements is achieved by the fact that at least one part of the test strip seating means, in the area in which, in the measuring position, the front section of the test strip is located, is formed as a support which is offset in height relative to the middle plane of the test field area, the test strip,,holding means comprising at the same time a pressure element which in the measuring position presses between the support and the test field area of the test strip against the side opposite the seating means of the latter. The test strip is consequently subjected to bending stress, whereby the particular distance of the at least one test field from the measuring unit is ensured.

Title: Procedure for synthesis of crystalline microporous silico-alumino-phosphates
Inventor: KVISLE STEINAR
IPC: C01B37/08
Filed: 1992-12-09
Abstract: The application concerns an improved method of producing silico-alumino-phospate catalysts for the conversion of methanol into light olefins such as ethylene and propylene (the MTO reaction). The improved method of synthesis can be used to control chemical composition of the silico-alumino-phosphates, especially the silicon content. In particular, it was found that catalysts can be synthesized that are more stable to deactivation by "coking", which is very important for the design of an MTO process based on the synthesized silico-alumino-phosphates.

Inventor: KEARNEY PATRICK
IPC: B65D65/40
Filed: 1993-11-30
Abstract: An improved method for manufacturing freeze dried pharmaceutical tablets in blister packs is disclosed. Liquid dosages are introduced into a multilayer laminated buster sheet having an impermeable intermediate layer (14) that is positioned between first and second outer layers (16, 18) each of which has substantially the same coefficient of thermal expansion. The properties of the outer layers of the blister sheet are such that there are no inter-layer stresses that will cause curvature of the buster sheet when it is subjected to temperature changes during the freezing and freeze drying sips. Following the introduction of the dosages into the depressions (10) of the blister sheet, the dosages are frozen and freeze dried. A lidding sheet (32) is then attached to the blister sheet to seal the solid dosages into the buster pack.
