Patent CA-2211245-A1 (CA)
Title: Armature pallet
Inventor: NERI PAOLO
IPC: B23Q7/14
Filed: 1997-07-23
Abstract: A pallet and system for transporting armatures along an armature manufacturing line, where the armatures may change in configuration at different stations of the manufacturing line, accommodates the various configurations without requiring a change of pallets at a station at which a configuration change occurs. The pallet has multiple sets of seats, each set corresponding to one of the configurations that the armature may assume during processing. Whenever the configuration of the armature changes from a first configuration to a second configuration, the armature, having been removed from a set of seats that accommodates the first configuration, is replaced in a set of seats accommodating the second configuration.      One way of accomplishing the transfer is, after lifting the armature from the first set of seats, allowing the pallet to advance by the distance separating the first and second sets of seats. The armature can then be lowered directly into the second set of seats without the need for lateral movement.

Title: Multipositional resealable vial connector assembly for efficient transfer of liquid
Inventor: JANSEN HUBERT
IPC: A61J3/00
Filed: 1997-08-26
Abstract: A connector assembly is provided for efficient flow of liquid into and/or out of a vial, such as a vial containing a lyophilized drug The connector assembly includes a spike slidably mounted in the open top of the vial. The connector assembly further includes a stopper sealingly engaged in the open top of the vial and slidably moveable in response to the axially movement of the spike. Thus, movement of the spike relative to the vial will move the stopper into or out of sealing engagement with the vial. The connector assembly further includes a spring for generating a small amount of axial movement of the spike after the stopper has been moved into the opened position in the vial. Movement of the spike generated by the spring will cause a sufficient change in pressure to overcome surface tension and initiate an efficient flow of fluid into or out of the vial.

Title: Geographically mapped telephone routing method and system
Inventor: NEVILLE DANIEL E
IPC: H04M3/487
Filed: 1997-12-23
Abstract: A method and system for direct routing of telephone calls made by a caller originating from within specific calling areas to one of a plurality of locations of a second party according to certain criteria established by the second party. This routing is accomplished based on the assignment of latitude and longitude coordinates to a potential caller's location. Once these coordinates are assigned to each of the potential callers, the second party's criteria is applied to assign the potential caller to a second party. Such criteria could be existence within a previously-defined geographic area, a custom defined geographic area, or through calculations such as the shortest distance between coordinate points. Once all such assignments have been made, a database is assembled to be used by a long distance carrier for direct routing of telephone calls from callers to an assigned second party.

Title: Oil-sealed vane-type rotary vacuum pump with oil feed
Inventor: ABELEN THOMAS
IPC: F04C29/02
Filed: 1996-07-12
Abstract: The invention concerns an oil-sealed vane-type rotary vacuum pump with a suction chamber (8) housing a rotatably mounted rotor (3) which has an anchoring section (21) and a bearing section (23) with a slot (24) in which two vanes (26) are mounted with a space (28) between them. The rotor bearing (3) comprises the bearing section (23) and a rotor-mounting bore (11). The vacuum pump also has an oil pump (45, 46), which produces a flow of oil through the space (28) between the vanes, and a system for controlling the flow of oil through the space (28), the oil passing through a channel (66) opening out in the rotor-mounting bore (11) and then through radial and longitudinal bores (68, 69) in the bearing section (23) of the rotor. In order to reduce the noise produced by the pump when in operation, the invention proposes that the location where the oil channel (66) opens out into the rotor-mounting bore (11) and the location of the radial bore (68) in the bearing section (23) of the rotor, with respect to the location of the vanes (26) or the vane-mounting slot (24), are such that oil can only flow into the space (28) between the vanes when the volume of the space is increasing, and that there is a permanently open line leading to the vacuum-suction chamber (8) for the oil leaving the space (28) between the vanes.
