Inventor: HAYHURST JOHN FRANKLIN
IPC: A62B1/06
Filed: 2007-12-11
Abstract: A device to enable a person to descend from an elevated position at a controlled and variable speed comprising a restraining member (12) having a series of slots (13). A tape (11) stored in a container (20) passes through the slots (13) to a hook (10) for attachment of the device to a fixed point. A user wearing a harness (21) removably attached to the restraining member (12) may descend at a controlled rate determined by the frictional engagement of the tape (11) with the surfaces of the restraining member (12).

Title: Green coal bed methane fracturing fluid composition, methods of preparation and methods of use
Inventor: LESHCHYSHYN TIMOTHY TYLER
IPC: E21B43/267
Filed: 2009-07-24
Abstract: The invention describes improved environmentally friendly, non-toxic, CBM friendly, green fracturing compositions, methods of preparing fracturing compositions and methods of use. Importantly, the subject invention overcomes problems in the use of water-based mists as an effective fracturing composition particularly having regard to the ability of a mist to transport an effective volume of proppant into a formation. As a result, the subject technologies provide an effective economic solution to using high ratio gas fracturing compositions that can be produced in a continuous (i.e. non-batch) process without the attendant capital and operating costs of current pure gas fracturing equipment.

Title: Method and apparatus for power control during dtx operation
Inventor: GHOLMIEH AZIZ
IPC: H04B7/005
Filed: 2008-01-31
Abstract: Techniques for performing power control during discontinuous transmission (DTX) operation are described. A UE transmits on the uplink during a transmission burst and receives TPC commands generated by a Node B based on the uplink transmission. The UE may receive two TPC commands at the end of the transmission burst that are not applied during the transmission burst. The UE saves and applies these two TPC commands in the next transmission burst. In one design, the UE applies each saved TPC command in one slot of the next transmission burst. In another design, the UE combines the two saved TPC commands and applies the combined value in the first two slots of the next transmission burst. In yet another design, the UE selects one of the saved TPC commands and applies the selected TPC command in the first two slots of the next transmission burst.
