Patent CA-2781486-A1 (CA)
Inventor: MEREY THOMAS G B
IPC: A47B88/969
Filed: 2012-06-27
Abstract: A rectangular expandible container has lateral compartments each of which being composed of inner and outer panels which slide relative to each other for lengthening and shortening the effective length of the compartments. The container also has front and back compartments defined by sliding panels for lengthening the effective width of the front and back compartments. A middle compartment is surrounded by the lateral compartments and the front and back compartments. The walls of the middle compartment are all slidable for lengthening both the width and the length of the latter compartment. The front and back compartment may contain partitions which separate the interior of those compartments into a number of sub-compartment of differing sizes for accommodating articles of varying sizes both in length and in width.

Inventor: WISNIEWSKI COLIN
IPC: F16B35/04
Filed: 2012-07-03
Abstract: Disclosed is a sink fastener for fastening a sink unit with an outer flange within an opening in a countertop. The sink fastener comprises a frame for attachment to a bowl wall of the sink unit, a threaded vertical bolt rotatably mounted within the frame, a claw member having a lateral portion threadably mounted on the vertical bolt and an upstanding retainer portion, and a guide member for constraining the movement of the claw member. In use rotation of the vertical bolt causes the claw member to rise up the bolt to engage an underside of the countertop, and in a lower disengaged position the claw member is free to turn about a vertical axis into a retracted position wherein the claw member lies constrained under the flange to permit insertion of the sink unit into the countertop opening. The guide member ensures that as the claw member rises up the bolt the claw member turns about the vertical axis into a constrained outwardly extended position for engagement with the underside of the countertop.
Patent CA-2784184-A1 (CA)
Inventor: RAGLIN JOHN M
IPC: E21B43/34
Filed: 2012-07-31
Abstract: A new method separating sand, solids, and produced particulates down-hole in a well producing hydrocarbons. The separation assembly can include ether one, two, or more segments or stages of varying lengths depending upon the individual application. The assembly is installed into the tubing string or delivery conduit of a well producing hydrocarbons. One stage can consist of a velocity chamber whereby separation of particulates occurs by increasing the downward velocity of particulates and reducing the upward velocity of hydrocarbons thereby allowing the particulates to "fall-out" into a lower chamber where the particulates are captured. Another stage can consist of a filter whereby particulates are captured in a chamber that can consist of filtering materials such as gravel, rock, sand, wood, or manmade materials. Each of the stages can be employed individually or in combination.

Title: Methods and system for verifying memory device integrity
Inventor: POTTER TIMOTHY STEVENS
IPC: G06F11/08
Filed: 2011-04-29
Abstract: A method for verifying memory device integrity includes identifying at least one memory block corresponding to at least one memory location within a memory device. The memory block is associated with a prior checksum. It is determined whether the first memory block is designated read-only. A current checksum is calculated based at least in part on data within the memory block. When the first memory block is designated read-only, and the prior checksum represents expected data within the first memory block, it is determined whether the current checksum is equal to the prior checksum. When the current checksum is not equal to the prior checksum, a verification failure for the first memory block is indicated via a notification interface. A system for verifying memory device integrity is also disclosed.

Abstract: The present invention provides a catalyst substance that is stable and performs well in the synthesis of ammonia, one of the most important chemical substances for fertilizer ingredients and the like. The catalyst substance exhibits catalytic activity under mild synthesis conditions not requiring high pressure, and is also advantageous from a resource perspective. Further provided is a method for producing the same. This catalyst comprises a supported metal catalyst having a mayenite compound, containing a conduction electron of 1015cm-3 or more, as a carrier for the ammonia synthesis catalyst. The mayenite compound used as the carrier may take any shape, including that of powder, a porous medium, a solid sintered body, a thin-film, or a solid single crystal. Use of this catalyst makes it possible for the electron donor ability toward a transition metal to be large, and to promote ammonia synthesis by reacting the starting material nitrogen and hydrogen on the catalyst under low reactive pressure between 10kPa and the 30MPa level at a reactive temperature between 100 and 600°C.

Abstract: A switching system enables monitoring granularity to be freely changed without awareness of routing control. For example, by using a control protocol for communication equipment that is compliant with the OpenFlow technology, and controlling the monitoring functions of the switching system, monitoring that enables the centralized control of an entire network is achieved, and the monitoring results are reflected in routing control. In this switching system, a switch stores a packet forwarding flow table and a monitoring flow table internally, searches both tables with respect to a single packet, and performs multi-hit operations for implementing the operation registered in each entry. In other words, the switch searches both tables, and forwards the packet according to all of the applicable flow entries.

Abstract: Broadband access networks are driving the upgrade of DWDM networks from 10Gb/s per channel to more spectrally-efficient 40Gb/s or 100Gb/s. Signal quality degradation due to linear and non-linear impairments are significant and error control coding and signal processing solutions play increasingly key roles in meeting increasing demand, providing improved quality of service, and reduced cost. It would be beneficial to reduce the power consumption of optical receivers for optical links exploiting for example LPDC  encoding.  Accordingly, the inventors have established a low complexity soft-decision front-end compatible with deployable LDPC codes in next-generation optical transmission systems.  Beneficially the optical receiver design can be retro-fitted into deployed hard-decision based optical systems and replaces the 3-to-2 encoder of the prior art in the electrical portion of the receiver with a single gate design. Further, the design may act as a 2-bit Flash ADC in multimode fiber based optical receivers.
