Patent CA-2385355-A1 (CA)
Inventor: WINKLER STEFFI LISSI
IPC: H04L12/70
Filed: 2000-09-18
Abstract: A method and arrangement for opening and closing communication channels by means of a private branch exchange is described. The transport network for transport of communication data is preferably embodied as an ATM network, controlled by a separate control network. In one particular version all decentralized relaying units are connected to each other via the transport network by means of virtual pathways. This guarantees that the formation of links via the transport network between any communication subscribers takes the same time. The time delay in forming a link only occurs during the initialization process of the transport network when virtual communication links are set up in the transport network.

Title: Convection fan assembly for a cooking appliance
Inventor: SWAYNE STEVEN M
IPC: F24C15/32
Filed: 2002-11-07
Abstract: A fan assembly for a convection cooking appliance defines a self-contained unit including a housing, an internal fan unit, and a cover. The cover is provided with a centrally located, unobstructed opening for directing air to an inlet for the fan unit. The area of the inlet opening is equal to or larger than the sum of the cross-sectional inlet area of fan unit. During operation, air is drawn into the fan housing through the opening, directed radially outwardly through the housing, and led out through radial, peripherally spaced holes of the housing. The overall construction of the fan assembly eases manufacture and assembly, while defining a high performance convection system by establishing an efficient recirculating airflow, with relatively high air flow, pressure and velocity operating parameters.

Patent CA-2425091-A1 (CA)
Inventor: BOSTIK KAREL
IPC: F16B31/02
Filed: 2003-04-11
Abstract: A single-part hollow shear coupling is provided for connecting a downhole pump with the terminal member of a sucker rod string. The coupling is threadably connected to the sucker rod and the pump during normal operations, but can relatively easily be parted, if the pump becomes stuck, by pulling up on the still free sucker rod string. One end of the coupling has a pin incorporating an externally threaded head and the other end has an internally threaded cavity. A cylindrical, hollow body joining both ends is weakened by the groove, providing a stress concentration point, where the coupling will part, when exposed to predetermined desired load. The weakened part of the shear coupling is protected with a special coating, preventing corrosion and abrasion.

Title: Cold tip rf/ultrasonic ablation catheter
Inventor: SHERMAN MARSHALL
IPC: A61B18/00
Filed: 2003-08-13
Abstract: A catheter for ablating internal tissue using radiofrequency (rf) or ultrasonic energy includes a mechanism to cool the catheter's distal tip. The catheter also includes either an rf electrode or an ultrasonic transducer positioned at the tip to direct energy into the internal tissue for tissue ablation.   With the distal tip of the catheter positioned adjacent the target tissue, a refrigerant is introduced into the catheter and allowed to expand near the catheter's distal tip. During expansion, the fluid refrigerant transitions from a liquid state to a gaseous state. Latent heat absorbed during the phase transition cools the tip of the catheter to a temperature sufficient to prevent tissue charring and coagulum formation during ablation. In another implementation, the catheter tip is cooled to a temperature sufficient to freeze tissue and create an ice-bail at the catheter tip that stabilizes the tip relative to the target tissue.

IPC: E21B41/02
Filed: 2003-09-16
Abstract: A protection system for an artificial lift device including but not limited to electrical submersible pump (ESP) and an electrical submersible progressing cavity pup (ESPCP). The artificial lift device is suspended on a tubing string into a wellbore where the artificial lift device contacts well fluids. The artificial lift device is provided with a barrier such as an intake barrier or output barrier that deters an ingress of well fluids into the artificial lift device. As a result, the artificial lift device may remain idle and submerged within well fluids for an extended period of time without experiencing degradation of the artificial lift device internal s. The intake barrier may include a plug, burst disk, dissolvable material, a selectively openable barrier such as a sleeve or a spring biased member or other member that is capable of providin g a suitable barrier. The barrier may be removed once the artificial lift device is ready for operation. The artificial lift device may be filled with a protective fluid. An optional pressure sensor ma y be provided that is in communication with the interior of the backup unit for communicating with a compressor that may be activated to maintain a positive pressure within the artificial lift device to prevent well fluids from entering the unit. The protection system of the invention is desirable for protecting an idle artificial lift device, including when the artificial lift device is a backup unit in a multi-artificial lift device deployment.

Title: Pneumatic hand tool exhaust muffler having inner and outer tubes
Inventor: STERLING ROBERT E
IPC: F01N1/10
Filed: 2001-04-02
Abstract: A muffler is provided for use in a pneumatic hand tool (10) having a handle (12) with an exhaust passage (16). The muffler includes an inner tube (30), an outer tube (32), an upper plate (36), and an end cap (44). The inner tube (30) is located within the outer tube (32), with one or more openings (38) being provided in each. The upper plate (36) is located near the inner tube (30) and is provided to close off the exhaust passage (16) so that a majority of the exhaust air is directed into the inner tube (30) during use. The end cap (44) attaches to the handle (12) for closing off the exhaust passage (16), but for one or more exit openings (46). During use, exhaust air enters the inner tube (30), flows out its penguins, flows out the outer tube (32) openings (40), and flows out the exit opening (46) in the end cap (44). The tortuous path slows the exhaust air and assists in dampening exhaust noise.
