Title: Method for preventing call congestion on outgoing trunks of a local telephone exchange
Inventor: LOTHIAN R BLAIR
IPC: H04Q3/00
Filed: 1998-01-27
Abstract: A system and method of preventing call congestion on  outgoing  trunks  of  a  local  telephone  exchange  is provided.   A virtual trunk group representing a percentage of  the  total  trunk  capacity  is  assigned  at the  local exchange  for  carrying  calls  which  are  likely  to  cause congestion.    In  one  embodiment  of  the  invention,    call segregation is achieved by using the prefixed dialling code 1+1  followed  by  the  destination  number.     In  another embodiment  of  the  invention,  segregation  is  dynamically achieved using Advanced Intelligent Network (AIN) routing.
Patent CA-2228990-A1 (CA)
Title: Isomerization process
Inventor: WILDERMANN ANGELA
IPC: C07B37/08
Filed: 1998-02-09
Abstract: A process for the catalyzed isomerization of a Z-isomer of a vitamin A compound or of a mixture of several of such isomers into a mixture of the corresponding all-E- and 13-Z-isomers of this vitamin A compound comprises using nitrogen monoxide or a gas mixture containing nitrogen monoxide as the isomerization catalyst. Moreover, the isomerization process is conveniently effected in a polar or apolar organic solvent at temperatures up to about 200°C and in such a manner that the catalytic contact with nitrogen monoxide is effected by introducing nitrogen monoxide or a gas mixture containing nitrogen monoxide, e.g. with nitrogen, into the (optionally dissolved) vitamin A compound to be isomerized and dispersing the nitrogen monoxide or the gas mixture containing nitrogen monoxide at atmospheric pressure or under slight over-pressure, e.g. up to 10 bar. Vitamin A acetate or vitamin A acid is preferably used as the vitamin A compound. The thus-produced all-E vitamin A and its alkanoyl esters have of all isomers by far the highest biological activity and are accordingly almost exclusively used in human and animal nutrition. The 13-Z-vitamin A compounds in turn play an important rôle as pharmaceutically active substances.

Title: Connector releasable in only one direction
Inventor: OTRUSINA EDWARD C
IPC: A45F5/02
Filed: 1998-02-06
Abstract: A connecting apparatus for detachably interconnecting two objects includes male and female structures respectively connectable to the objects. The female structure is of unitary, one-piece construction having parallel planar walls cooperating to define a receptacle therebetween, one wall having an aperture therein communicating with the receptacle and extending to a peripheral edge of the wall for opening thereat to define an entrance. An inclined flexible and resilient cam portion is laterally offset to one side of the entrance and is integral with the one wall and inclined out of the plane thereof toward the other wall. Male structure has a stud projecting therefrom with a part-circular head having a straight side and dimensioned to pass through the entrance so that, in one rotational orientation of the head, it will clear the cam portion to permit free passage into and out of the receptacle. In all other rotational orientations the head will engage the cam portion, flexing it to permit movement of the head into the receptacle, but wedging against it to inhibit movement out of the receptacle.

Title: Method of determining dew point and a suitable device
Inventor: STEPANOV ANDREI ROBERTOVICH
IPC: G01N21/47
Filed: 1996-07-16
Abstract: The proposed method of determining dew point involves directing the gas under investigation onto a cooled section of an optically transparent body through which a luminous flux is allowed to pass and recording fluctuations in the intensity of the luminous flux, the flow-rate of the gas thus directed onto the cooled section being reduced down to zero while its molecular diffusion is preserved. To limit the flow-rate of the gas impinging on the cooled section (1) and reduce contamination of the optically transparent element, the dew point gauge is provided with a sampling tube (10).

Title: Dragline bucket dump compensator
Inventor: FLECK ROBERT S
IPC: E02F3/58
Filed: 1998-07-22
Abstract: A hoisting assembly for use with a dragline bucket that includes a compensator for generally stabilizing the attitude of the bucket.  The compensator is operably coupled to the lift, hoist and dump lines.   The connector for the lift line(s) defines a fulcrum about which the compensator turns during use.  As the tension in the dump line increases relative to the tension of the hoist lines, the compensator turns about the fulcrum to lift the hoist lines and shift the sheave supporting the dump line forward.          As the tension in the dump line decreases relative to the tension of the hoist lines, the compensator turns about the fulcrum in the opposite direction to lower the lift lines and shift the sheave supporting the dump line rearward.

IPC: B25B13/50
Filed: 1999-02-01
Abstract: Je suis dans le domaine des abris d'autos depuis plusieurs années. Un problème subsistait au montage et au démontage des abris. Il n'y avait aucun outil manuel sur le marché pour visser et dévisser les écrous papillons servant à l'assemblage de la structure. Nous devions donc les visser à la main, ce qui ne permettait pas de les serrer adéquatement et les écrous dévissaient très souvent durant l'hiver, rendant l'abri d'auto moins solide et moins sécuritaire. Mon invention vient en 2 versions: une version manuelle et une autre qui s'adapte à une perçeuse électrique ou à batterie. Elles ont pour fonction de visser et dévisser les écrous papillon 1/4 20. Les outils en question s'ajustent parfaitement à la forme des écrous papillons de toutes les marques et modèles sur le marché.

Abstract: The present invention provides IP multicast using over wireless ATM. A wireless ATM system consists of a fixed core network and a shared wireless access link for mobile terminals.      Unlike point-to-point ATM links within the fixed/wired network, wireless ATM link uses a common VC space for all mobile terminals and the medium access (MAC) protocol allows multiple access on the downlink, but supports only unicast transmission on the uplink. This invention also provides how IP multicast can be naively supported on such WATM links through specific extensions to the Internet Group Management Protocol (IGMP). In addition, a cell-level error recovery scheme at the DLC (data link control) layer is provided to enhance the (IP) packet-level output of the transport layer.

Title: Method for applying guidelines for visually handicapped persons, and a mould adapted for the application of the method
Inventor: GRAHMBEEK TAMAR VANESSA
IPC: E01F9/04
Filed: 1999-03-17
Abstract: The invention relates to a method of applying guidelines or guideribs in the walking direction for visually handicapped persons. The method is adapted for application in situ on an existing hard subsoil. It is, however, also adapted for the application of these guidelines or guideribs on tiles, etc., before the tiles are mounted. The method relates to the application of one or more groups of tight interrupted ribs parallel to each other, which as a group form a desired path width. Use is made of epoxy resins with additives, amongst which quartz powder in order to increase the strength against wear. The ribs formed have a rectangular vertical cross-section which is easily perceptible for visually handicapped persons with their cane or foot. As a result of the sharp corners the attention value is high, notwithstanding the fact that the rib is low. This gives a minimum of inconvenience for other users of the path and the ribs can easily be maintained.
