Patent CA-2506426-A1 (CA)
Title: Apparatus and method for drilling and reaming a borehole
Inventor: EPPINK JAY M
IPC: E21B10/32
Filed: 2003-11-20
Abstract: A drilling assembly (100) and an eccentric, adjustable diameter reamer (10) are disclosed. The reamer includes cutter elements mounted on at least a first fixed blade (30) for reaming a previously-formed borehole or for forming a borehole of increased diameter beneath an existing cased borehole. The method and apparatus provide for stabilizing the drilling assembly so that the reamer may be used in back reaming the hole. Retainer means, such as shear pins (426) or spring-biased reciprocating latch members (650, 680), are provided to prevent premature extension of the reamer's moveable members (40), including blades and pistons. The shear pins are preferably accessible from the outer surface of the reamer housing so as to expedite field replacement of the shear pins without requiring disassembly of the reamer. The spring-biased latching members repeatedly latch and unlatch so that field replacement is not required.
Patent CA-2509003-A1 (CA)
Title: Non-isolated dc-dc converters with direct primary to load current
Inventor: LIU YAN-FEI
IPC: H02M3/28
Filed: 2003-12-09
Abstract: DC-DC converters (301) have high side (305) and rectifier circuits (304), and output capacitor (Co). High side circuit connects between input voltage and output voltage, and has primary winding and auxiliary section that operate transformer properly. Auxiliary may have switches or combination of switches and capacitors. High side circuit converts electrical into magnetic energy through transformer primary, which is then transferred to output through rectifier circuit. It also transfers energy directly to output voltage.  Converters have high efficiency, fast dynamic response and high current output. Converters can have large duty cycle and large input voltage and output voltage conversion ratio. High side circuit can be half-bridge, full-bridge or forward converter. Rectifier uses inductors on either side of the secondary, and diodes or synchronous rectifiers, to rectify output voltage.  Multi-phase interleaved circuits utilize shared switches to reduce size. High side circuit can utilize resonant tank to decrease switching losses in auxiliary.

Title: Method and apparatus for discovering computers for storing fragments of files in a computer network
Inventor: MCKEE PAUL FRANCIS
IPC: G06F17/30
Filed: 2003-12-11
Abstract: The discovery process comprises the device (10) generating messages (112, 12 0 126) which together have the purpose of identifying a predetermined number o f devices which satisfy a test condition included in each message. These messages are sent respectively to the on-line devices (12, 20, 26) neighbouring device (10). To ensure that no more devices than necessary are identified by the messages, each message includes a variable which is referr ed to as a token bucket which indicates the number of devices to be discovered by the message. Additionally, each message includes a unique identifier. When a device (12, 20 26) receives a discovery message sent from another device, it determines if it satisfies the test condition and if so it sends an acceptan ce message to the originating device, decrements the token bucket in the messag e and forwards on any remaining tokens to another neighbour. The process stops once all tokens have been disposed of in this way. If a message reaches the end of a path without disposing of all of the tokens, the message is returne d back up the path to try different paths until eventually all paths have been tried or a restriction criterion (eg maximum permitted number of hops) is me t whereupon the message is returned back as a failed message to the originatin g device.
Patent CA-2513400-A1 (CA)
Title: Short radius whipstock system
Inventor: SONI MOHAN L
IPC: E21B7/06
Filed: 2004-01-12
Abstract: A short radius exit from a window milled in casing is possible using a whipstock (10) with a sloping surface in excess of 3.5~ and a window mill (16) whose diameter is reduced to a percentage generally below about 95% of the casing inside diameter in a mono-bore or non-through tubing application. The system provides a greater flexibility in choosing the window location and eliminates having to penetrate adjacent formations as compared to previous techniques using a longer exit radius. The decrease in mill diameter, as compared to previous techniques, limits stresses on the milling equipment to minimize equipment failures during window milling and subsequent drilling of the lateral.

Title: System and method for ultrasound c-scanning
Inventor: BLALOCK TRAVIS N
IPC: G01S15/89
Filed: 2004-01-15

On a time serial or sequential basis, several times for each line of firing, the contents of the per element memory buffer are read into the beamformer with different focusing values for each buffer reading cycle. In this way, the beamformer can calculate beamformed image values for multiple points per line firing cycle-or per each line of signals between the transducer array and receive beamformer.

Abstract: A breather air and food product fines pumping system for a reciprocating mold plate food product forming machine (20) pumps air and fines to a collection area. A pumping surface is provided by a rearward facing surface of the mold plate (32). A pumping chamber (69) is arranged between the pumping surface and a food product fines collection area. The rearward facing surface of the mold plate defines a movable limit of the pumping chamber. A valve element of a first valve (107) is arranged between the pumping chamber and the collection area to create suction in the pumping chamber when the rearward facing surface of the mold plate is moving forward, and to allow the pumping chamber to pump air and fines into the collection area when the rearward facing surface of the mold plate is moving rearward. Breather holes (216) in a breather plate (122) are in communication with a breather passage that is in communication with the pumping chamber and with outside air through further valve arrangements. The further valve arrangements and the first valve act to flush the breather passage with outside air to drive air and fines in the breather passage into the pumping chamber where it is then pumped to the collection area.

Abstract: Disclosed here are systems and methods to enable configuration of functional components in integrated circuits. A present invention system and method can flexibly change the operational characteristics of functional components in an integrated circuit die based upon a variety of factors including manufacturing defects, compatibility characteristics, performance requirements, and system health (e.g., the number of components operating properly). Functional component operational behavior is tested and analyzed at various levels of configuration abstraction and component organization (e.g., topological inversion analysis). The testing and analysis can be performed in parallel on numerous functional components. Functional component configuration related information is presented in a graphical user interface (GUI) at various levels of granularity and in real time. The graphical user interface can facilitate user interaction in recognizing failure patterns, production test tuning and field configuration algorithm adjustment. The testing and analysis information can also be organized in a variety of convenient database formats.

Abstract: Il est décrit un congélateur de type à transport pour refroidir ou congeler un élément de travail placé sur un transporteur à courroie en soufflant de l'air froid vers l'élément de travail depuis des buses à fente agencés au-dessus et au-dessous du transporteur à courroie. Afin de maintenir un effet de refroidissement intense et d'éviter que la formation d'un passage de décharge d'air froid n'affecte l'effet de refroidissement, un flux à jet rectiligne avec une distance de portée élevée est généré pour former, par effet Coanda, un flux en couche mince en contact étroit avec la surface de l'élément de travail. Dans ce but, des buses à fente (5a, 6a) sont agencées en continu côte à côte dans la direction de transport d'un transporteur (2) et placées en forme de chevron, de manière à former une section de passage d'air froid en amont des ouvertures de buse. Grâce à cela, un flux à jet rectiligne avec une vitesse de projection élevée est généré, et un passage de décharge pour évacuer le flux d'air froid après la projection sur les deux côtés d'un transporteur (2) est formé en continu dans un évidement (12) entre les buses à fente. Le passage de décharge ainsi formé n'interfère pas avec l'installation des buses à fente.
