Patent CA-2280558-A1 (CA)
Inventor: LENIEK HUMBERTO F
IPC: E21B19/22
Filed: 1999-08-20
Abstract: Accordingly, an improved pumping system is herein disclosed. In one embodiment, the pumping system includes a subsurface pump, a tubing string, and a surface pumping unit. The subsurface pump is anchored downhole and driven by repeated upward and downward motion of the tubing string. The subsurface pump pumps fluids to the surface via the tubing string. The upward and downward motion of the tubing string is imparted by any suitable surface pumping unit such as, e.g. a beam pumping unit or a hydraulic pumping unit. This pumping system advantageously provides for a minimal number of strings downhole, requiring at most only (1) casing and (2) the production tubing. Accordingly, the well may be drilled using a very slender hole, thereby allowing for sharply reduced drilling and production costs.

Patent CA-2285195-A1 (CA)
Title: A connector
Inventor: WILCOX DAVID MARK
IPC: H01R13/646
Filed: 1998-04-16
Abstract: A connector for making an electrical connection with a mating interface (17) includes a hollow conductor (1) within which is included a member (9) which is relatively movable with respect to the conductor (1). Resilient means (12), which may be a spring, is located between the conductor (1) and member (9). In a first state of the connector, the conductor (1) and member (9) are in a relative position in which the resilient means (12) exerts a force between them urging them together. Following a mechanical connection made between the member (9) and the mating interface (17), the connector is set in a second state in which the force applied by the resilient means (12) takes effect, moving the conductor (1) and member (9) towards one another to make an electrical connection between the conductor (1) and the mating interface (17). This allows a connection to be made with only minimal force and no torque, making it suitable for fragile connections. It is particularly useful for connections which must be made under vacuum.

Patent CA-2294357-A1 (CA)
Title: Electrical plug
Inventor: GIBBONEY JAMES W JR
IPC: H02H9/02
Filed: 1997-07-30
Abstract: A plug (100) is disclosed that is adapted to be inserted into a standard electrical outlet and has a built-in integrated circuit (18) for rectifying the alternating current received from the outlet and limiting the direct current produced. The plug (100) is specifically suited for low-current, low-voltage applications such as supplying DC to a string of ornamental lights. The integrated circuit (18) has a diode (24) with a modified cathode that acts as a fuse as it is rectifying the alternating current. The cathode is formed of a plurality of electrically parallel conductors. Excessive current blows out at least some of these conductors in the same way a conventional fuse blows. Various embodiments add other current-limiting elements, elements for producing full wave or near full wave rectification, and for opening the circuit when they detect extraneous currents.

Patent CA-2302959-A1 (CA)
Title: Priority resource allocation in programming environments
Inventor: POLAN MICHAEL G
IPC: G06F9/50
Filed: 2000-03-23
Abstract: An extension to a programming language provides for the fair allocation of resources in the programming language environment. A resource pool data object stores available resource objects. A resource queue stores users waiting for resource object allocation. A method releases resources by placing the resources in the resource pool and by notifying users that a resource object has been released. An acquire resource method provides for users to be placed on the resource queue when there are no available resource objects. The acquire resource method waits on the availability of the resource object until the user comes to the head of the resource queue and a resource object is available, following which the resource object is returned to the user.  Alternatively, a time out condition is reached once a predefined wait limit is met. The synchronization between methods and users waiting on resources is provided by the acquisition and release of a common lock.
