Title: Process for producing ethylenedichloride in fluidized bed by oxychlorination of ethylene, as well as process for producing the necessary catalyst
Inventor: EDEN JAMAL S
IPC: C07C19/045
Filed: 1987-08-19
Abstract: A fluidizable catalyst composition is provided containing about 2% to about 8% by weight of copper (about 4% to about 17% by weight of copper salt), from about 0.2% to about 10% by weight of a rare earth metal salt(s), preferably the chloride salt(s), and from about 0.25% to about 2.3% by weight of an alkali metal salt(s), preferably the chloride salt(s), all weight percents based upon the total weight of the catalyst composition. The metals are codeposited on a fluidizable, high surface area alumina support. The weight of the alkali metal employed is not over 2.5% by weight (as the chloride) and the weight ratio of the rare earth metal salt(s) to the alkali metal salt(s) must be at least 0.8:1. Such catalyst compositions are extremely useful as fluid bed catalysts in the vapor phase oxychlorination reaction of ethylene, oxygen and hydrogen chloride to produce 1,2-dichloroethane (EDC). The use of the catalysts results in improved, high percent ethylene efficiencies and high percent HCl conversions, and avoids operating problems caused by stickiness of the catalyst in the fluid bed. A combination of copper chloride, potassium chloride and one or more of the rare earth chlorides on a fluidizable gamma alumina support, produces an excellent catalyst for a fluid bed ethylene oxychlorination process.

Title: Building radiation protection system
Inventor: MUGGIOLI GIANFRANCO
IPC: G21F/
Filed: 1987-08-19
Granted: 1989-12-29
Abstract: The system generates a digital pixel image in a framestore memory (20) by expanding run-length encoded data stored in a command memory (22). Each pixel has a variable characteristic such as its colour, or its depth in a 3-D image. The value of the characteristic for each written pixel is determined from the run-length encoded characteristic. The value of the characteristic for each pixel in the run is determined from a reference parameter which determines the initial value of the characteristic, and a difference parameter which represents the change in the value along the length of the run. The coordinates of the pixel runs may be determined from the coordinates of a preceding run. The initial location and run length for each run are determined relative to the preceding run by delta parameters associated with the current run. The system generates linear colour blends and automatically depth-clips images being written into the framestore (20).

Title: Improved catheterization system
Inventor: LEWIS JEFFREY P
IPC: A61M5/158
Filed: 1993-06-17
Abstract: This invention relates to an improved arterial catheterization system which is designed to allow the user to quickly visualize the early flashback of blood after penetration of a vessel. The improved arterial catheterization system of this invention allows for minimum blood loss during initial penetration of the blood vessel. Specifically, this invention is directed to a system for introducing an over-the-needle catheter into a blood vessel, and comprises an inserter unit having a hollow needle and a catheter having a lumen such that the catheter is adapted to be carried on the needle. The catheter and needle cooperate to form a first flashback chamber therebetween. The first flashback chamber is at least partially translucent and allows for the visualization of blood flow upon insertion of the needle into a blood vessel. A guide wire, which is slidably mounted on the inserter unit within the needle, is dimensioned in relation to the needle in order to provide a blood flow passage therebetween. A second flashback chamber is formed in the inserter unit and connected to the needle to receive blood flow. The guide wire serves as a guide for the catheter as the catheter is advanced off of the needle, along the guide wire and into the blood vessel. The guide wire and the catheter are separable after the catheter is placed in the blood vessel.
