Title: Monitoring apparatus
Inventor: DALGLEISH MICHAEL
IPC: G08G1/16
Filed: 1990-05-04
Abstract: ABSTRACT OF THE DISCLOSURE          Monitoring apparatus for monitoring traffic flow in a tunnel, comprising a plurality of cameras each connected to a camera controller.  Each camera controller includes an image memory for periodically storing still images from the camera associated therewith.  A plurality of incident detectors are associated with each camera.  The incident detectors detest the passage of vehicles and determine whether or not a traffic incident, eg congestion or an accident, has occurred in accordance with an algorithm.  When an incident has occurred an incident detection signal is generated which is communicated to the camera controllers.  The image memory of the relevant camera controller is responsive to the detection signal to identify and freeze a plurality of images prior to the incident which are then passed to the central controller, so that the circumstances leading up to the incident can be reviewed.

Inventor: ENGEL-BADER MONIKA
IPC: C08G63/83
Filed: 1990-09-26
Abstract: A novel catalyst composition, and a process for using the novel catalyst system to produce polyester is described.  The novel catalyst composition is specific for producing polyester from a lower dialkyl ester of a dicarboxylic acid and glycol, wherein the catalyst composition includes from about 20 ppm to about 150 ppm manganese; from about 50 ppm to about 250 ppm lithium; from about 10 ppm to about 40 ppm cobalt; and from about 200 ppm to about 400 ppm antimony, all amounts being based upon the expected yield of the polyester.  The process for using the novel catalyst composition to make polyester includes the step of employing an effective catalytic amount of manganese and lithium in an ester interchange reaction from a lower dialkyl ester of a dicarboxylic acid and glycol to produce monomer; and using an effective catalytic amount of cobalt and antimony in the polycondensation reaction to convert the monomer to polyester.  Using the novel catalyst composition or novel process to produce polyester drastically increases both the ester interchange rate and the polymerization rate, such that the ester interchange time and the polycondensation time are drastically reduced as compared to more conventional systems for producing polyester.

Title: Polyacetal resin composition and guide member for magnetic tape travel
Inventor: TAKAYAMA KATSUNORI
IPC: C08L59/02
Filed: 1990-10-17
Abstract: ABSTRACT      Self-lubricating polyacetal resin compositions and molded articles (e.g. "wear parts") formed thereof include a polyacetal base resin, and a self-lubricating effective amount of a silica powder in which a silicone polymer (e.g. silicone oil) is absorbed.  The silica powder acts as a carrier for the silicone polymer so as to improve the dispersibility of the silicone polymer in the polyacetal base resin as well as to allow greater silicone polymer "loading" of the polyacetal base resin.  As a result, improved lubricant dispersibility and sliding characteristics are achieved.
