Patent CA-2416286-A1 (CA)
Title: Syringe plunger locking mechanism
Inventor: MCPEAK THOMAS J
IPC: A61M5/315
Filed: 2001-07-20
Abstract: A injection system having a syringe body which defines a pumping chamber. A  syringe plunger is located in the pumping chamber and is adapted for reciprocal motion within the pumping chamber. The syringe plunger includes a capture member projecting outwardly in a proximal direction. An actuating shaft is coupled to the syringe plunger and is movable through the syringe body to control movement of the syringe plunger. The capture member is adapted to flex radially outwardly when contacted by the actuating shaft to form a releasable engagement with the actuating shaft when the actuating shaft and the capture member are in an engagement position. A release actuator is disposed proximal to the syringe body, and the capture member releases the actuating shaft upon engagement with the release actuator.

Abstract: A pylon or barrier arrangement which is recessed into the ground or other surface and includes a post-like pylon which is movable between an extended position for control of vehicular or pedestrian traffic, and a retracted position beneath the ground. Movement of the pylon is achieved by a linear- type drive mechanism which acts as a clutch by decoupling from an upright an d rotatable smooth drive shaft during abrupt downward driving of the pylon to avoid damage to the internal components of the arrangement. A sealing arrangement is provided for preventing the entry of debris into the interior  of the pylon arrangement, and a heating unit is provided for preventing seizure of the arrangement during harsh weather conditions.

Patent CA-2421210-A1 (CA)
Inventor: AMPULSKI ROBERT STANLEY
IPC: D21F11/00
Filed: 2001-08-31
Abstract: A papermaking belt for use in making paper. The papermaking belt, which has a paper-contacting face and a machine-contacting face, may be used in conjunction with a single-wire draw or twin-wire draw of a papermaking machine. The papermaking belt comprises a woven reinforcing element and a patterned framework. The framework defines either or both faces of the papermaking belt, such that a first face of the framework provides at least 90% of the surface area of the paper-contacting face. The pattern of the framework is independent of the weave of the reinforcing element. This arrangement decouples the amount and pattern of the paper-contacting surfaces of the belt from the weave and/or permeability of the belt. Further, this arrangement allows for increased and more uniform contact area of the paper web against a drying cylinder. Additionally, this belt provides an increased wear surface for improved belt life.

Patent CA-2428171-A1 (CA)
Inventor: JUNDT JACQUES
IPC: E21B47/12
Filed: 2003-05-07
Abstract: A robust, low-loss wired pipe joint is provided for service as a component of a wired pipe string for transmitting measurement data to a surface station from locations in a borehole in oil well drilling and oil well operations. Conductive layers reduce signal energy losses over the length of the drill string by reducing resistive losses and flux losses at each inductive coupler. The wired pipe joint is robust in that it remains operational in the presence of gaps in the conductive layer. A wired pipe joint includes an elongate tubular shank having an axial bore, a threaded box-end, and a threaded pin end. A first annular coil, fixedly mounted to the box-end is partially surrounded by a first high- conductivity, low-permeability layer, and a second annular coil fixedly mounted to the pin- end is partially surrounded by a second high-conductivity, low-permeability layer, such that when the box-end of a first wired pipe joint is coupled for operation with the pin-end of a second wired pipe joint, the first and second high-conductivity, low- permeability layers form at least a portion of a toroidal path enclosing the first annular coil of the first wired pipe joint and the second annular coil of the second wired pipe joint. Coil windings of the first and second coils of the wired pipe joint are electrically coupled.
