Patent CA-2153830-A1 (CA)
Title: Rail attachable rescue frame for rail bridges
Inventor: O'ROURKE MICHAEL J
IPC: A62B1/04
Filed: 1995-07-13
Abstract: The present invention is directed to a rail bridge rescue frame. The frame comprises three elongated legs having upper and lower ends. The upper ends are secured to a head assembly so as to universally pivot with respect thereto. Two of the legs are forward legs of shorter and similar length and the third is a rear leg of longer length. Means are secured to the lower end of each of the forward legs to bear against a side portion of a rail. Means are attached to the lower end of the rear leg to secure to a portion of a rail. The frame is constructed so that when the rear leg is secured to one rail of a railway and the lower ends of the forward legs are bearing against outer portions of an adjacent rail thereof, the head assembly will be positioned clear of the railway to one side to provide support for a line to lift a person or the like below the railway up to the level of the railway.
Patent CA-2153978-A1 (CA)
Title: Ethylene interpolymerizations
Inventor: KOLTHAMMER BRIAN W S
IPC: C08F110/02
Filed: 1994-01-28
Abstract: Processes for polymerizing ethylene/a-olefin interpolymer compositions are disclosed. The interpolymer compositions have a controlled composition and a controlled molecular weight distribution. The processes utilize a highly-efficient homogeneous catalyst composition in at least one reactor to produce a first interpolymer having a narrow composition distribution and a narrow molecular weight distribution, and a highly-efficient heterogeneous Ziegler catalyst in at least one other reactor. The reactors can be operated sequentially or separately, depending upon the desired product. The novel compositions have good optical properties (e.g., clarity and haze) and good physical properties (e.g., modulus, yield strength, toughness and tear).  Useful products which can be formed from these compositions include film, molded articles and fiber.
Patent CA-2154356-A1 (CA)
Inventor: SCHMIDT WILLIAM
IPC: A61K9/70
Filed: 1994-02-24
Abstract: A protective aqueous antimicrobial film forming compostion that can be applied to dairy animals to form a protective film. The film can be used to reduce the incidence of both contagious and environmental mastitis in dairy herds and can be formed from an aqueous compostion that can contain a nonionic iodine complex, a polyvinyl alcohol composition, having a degree of hydrolysis greater than 92 %, preferably greater than 98 %, and a thickener. The aqueous mixture can be applied to udder and teats of dairy herds to form a protective coating that can prevent infection from staphlococcus, streptococcus, klebsiella and other pathogens.  The film can be removed using water in a convenient short period of time permitting efficient milking operations.  After milking, the composition can be reapplied to the herd and can protect the herd from mastitis until the herd is again milked. The material of the invention has the property that after application and drying both films and plugs of the protective coating is softened and removed even in cold water in a convenient time frame.

Title: Game play media lending machine and gaming house management system
Inventor: TAKEMOTO TAKATOSHI
IPC: G07F7/08
Filed: 1994-03-07
Abstract: In a game play media lending machine (20) of the invention, a control section (47) checks a player who uses a credit card for identification by comparing information read by a credit card reader (27) with information entered through an identification data input means (28). If they match and the player is identified as the credit card holder, game play media are dispensed to the player. When the lending amount for playing a game with the credit card is set, a lending card issuing section (43) issues a lending card such as a receipt on which the lending amount and the lending amount setting date and time are entered. Thus, the lending machine (20) performs all procedures concerning use of the credit card as well as dispensing the game play media.

Title: Catalyst, method and apparatus for a particle replacement system for countercurrent feed-packed bed contact
Inventor: BACHTEL ROBERT W
IPC: B01J23/16
Filed: 1995-04-27
Abstract: This invention makes possible substantially continuous flow of uniformly distributed hydrogen and hydrocarbon liquid across a densely packed catalyst bed (10) to fill substantially the entire volume of the reactor (11) by introduced the liquid and gas as alternate annular rings at a rate insufficient to ebullate the bed. Catalysts are selected by density, size and shape at a design maximum feed rate of fluids to prevent the ebullation of packed bed. The alternate annular rings flow across the full area of the bed. The catalyst flow in a continuous, downward plug-like manner is achieved by the introduction of the catalyst at the top of the bed in a laminarly flowing liquid on a periodic or semicontinuous basis. Catalyst removal is also achieved by laminar flow in the same fashion from the bottom. The catalyst used produces a plug-flowing, substantially packed bed.
