Patent CA-2745686-A1 (CA)
Inventor: SVEUM MATTHEW
IPC: B65G69/28
Filed: 2011-07-07
Abstract: Example dock levelers at a truck-loading platform include a stationary curved transition plate extending between a rear edge of the leveler's pivotal deck and a rear edge of a pit at which the leveler is installed. The transition plate has a curved portion that extends underneath the deck's rear edge. The plate provides a smooth transition for forklifts traveling between the platform and the deck, thus reducing and/or minimizing the jarring of the forklift and its driver. To prevent debris and obstructions from getting trapped within the deck's rear hinge, the rear edge of the deck rises up and over the transition plate as the deck pivots upward, thereby providing a self-cleaning effect. With the rear edge of an inclined deck being above the transition plate, water runoff from the deck drains onto the transition plate rather than through the hinge gap to a generally inaccessible area underneath the deck.

Title: Automatic heat-conserving clean water supply device for livestock
Inventor: SHIN IL HYUN
IPC: A01K7/02
Filed: 2010-07-09
Abstract: The present invention relates to a water supply apparatus installed in a cattle shed for raising livestock such as milk cows or the like. More particularly, a drinking trough including an inner casing, an outer casing and an elevating body is installed below an upper surface of a water tank, and the elevating body has a bottom with an open/shut valve body. A water supply pipe with an on/off valve, a water drain pipe, an overflowing water pipe, a heater, a water level sensor and a temperature sensor are installed in the water tank to enable livestock such as milk cows or the like to drink from the elevating body containing a predetermined quantity of water. The open/shut valve body installed on the elevating body enables a constant quantity of water to be contained in the elevating body, and simultaneously prevents foreign substances from entering the water tank to prevent the water from being spoiled. In addition, the drinking trough arranged in the upper portion of the water tank is opened to a minimum degree for enabling the drinking of water, and thus causes a minimum loss of heat, thereby achieving improved heat-insulating effects in the wintertime, and providing clean water with an optimum temperature at all times.

Title: Using metadata in security tokens to prevent coordinated gaming in a reputation system
Inventor: NACHENBERG CAREY
IPC: G06F21/00
Filed: 2010-09-10
Abstract: To prevent gaming of a reputation system, a security token is generated for a security module using metadata about the client observed during the registration of the security module. The registration server selects metadata for use in generating the security token. The generated security token is provided to identify the client in later transactions. A security server may conduct a transaction with the client and observe metadata about the client during the transaction. The security server also extracts metadata from the security token. The security server correlates the observed metadata during the transaction with the extracted metadata from the security token. Based on the result of the correlation, a security policy is applied. As a result, the metadata in the security token enables stateless verification of the client.

IPC: F28G1/06
Filed: 2012-08-14
Abstract: A hose reel assembly, system and method for cleaning tubes, particularly heat exchanger tubes, which system includes independently rotatable inner and outer drums. The inner drum is rotated in a first or second direction by a first motor assembly to wind a hose disposed in a gap between the drums, off of or onto the inner drum. A second motor rotates the outer drum causing rotation of a nozzle on the hose about the hose's longitudinal axis and at speeds of about 100 to about 1600 rpm. The nozzle delivers a water jet at pressures of up to about 55,000 psi to cut through deposits in the bores of the exchanger tubes. The nozzle is mounted on an indexer movable within the heat exchanger and a camera and joystick on a remote console enables an operator to view the cleaning operations and manipulate the nozzle in relative safety.

Patent CA-2787806-A1 (CA)
Inventor: EISENBARTH DARWIN SPENCER
IPC: F02D41/30
Filed: 2012-08-27
Abstract: An engine control unit with distributed processing includes a main ECU and remote modules with sensor inputs and ignition and injector outputs. A bidirectional asynchronous CAN data bus and a square wave timing signal operatively connect the components.  Synchronous ignition and ignition data and asynchronous sensor and control data are concurrently transmitted between components using CAN messaging. Synchronicity is accomplished using the timing signal. The rising edge of each pulse triggers dwell and injection start times, and the falling edge triggers ignition. Injection and dwell time values, the cylinders to dwell and fire, and the injectors to energize, are transmitted using CAN  messaging. The remote modules process the control messages and timing signal and generate the appropriate ignition, injector, and pulse width modulation control signals. Alternatively, time stamp capabilities of the CAN bus topology are used for synchronization. The system and methodology simplify interconnection, using fewer wires and enhancing aesthetics.
