Abstract: In order to produce a granulated material from a powder mixture containing at least two components, one of which is in crystal or crystalline form and at least one contains water of crystallization and/or is reactive, granulation is carried out in an inclined drum. Powder is fed in at one end and granulate removed at the other, after being transported inside the drum for a desired period while the drum is rocked in a way which largely eliminates shear forces. A quantity of liquid at least approximately equal to the quantity of water of crystallization present and sufficient for the formation of a superficially active solution adhesive is released inside the drum, where appropriate by partial reaction of the reactive component(s), after which the powder mixture components are granulated by surface adhesion.

Granted: 2003-07-15
Abstract: A dual bore completion sub-sea test tree (10) is described which has main bore (18) and an auxiliary or annulus bore (20). Two identical ball valves (22, 24) are located in series within the main bore (18) and two smaller identical ball valves (26, 28) are located in series in the annulus bore (20). The ball valves (22, 24, 26, 28) are operated by respective independent control lines acting on the operating mechanisms of the respective valves within the test tree(10) to move the valves between open and closed positions to allow or deny communication through the respective bores (18, 20). The completion sub-sea test tree (10) provides isolation of the main bore (18) and/or the annulus bore (20) when required by application of hydraulic pressure to assist closure to spring forces sufficient to cut coil tubing in the event of an emergency situation requiring rapid disconnect. Hydraulic across the tree disconnect is achieved using independent hydraulic stabs which can selectively isolate or allow the hydraulic systems to vent when disconnected. A helical guide (82) and axial slot (81) are provided on the surface (16, 83) of the housing to engage with a pin (84) on a BOP stack to orientate the tree (10) correctly to a tubing hanger (86).

Title: Methods of fracturing subterranean formations
Inventor: BROWN J ERNEST
IPC: C09K8/62
Filed: 1997-10-07
Granted: 2001-05-29
Abstract: The improved recovery of hydrocarbons from subterranean formations by hydraulically fracturing a subterranean formation is accomplished. Fracturing fluids using a viscoelastic surfactant fluid containing wormlike micelles are useful to improve recovery of hydrocarbons and limit the loss of fracturing fluid into the formation fracture face.  The invention further relates to novel fracturing methods useful for increasing hydrocarbon production, limiting connate water production, resisting fracturing fluid loss into the subterranean formation, and reducing the equipment requirements in mixing and pumping fracturing fluid. The action of micelles of surfactant in aqueous zones of the subterranean formation facilitates the flowback of increased amounts of hydrocarbons once a fractured well is placed back on production.

Title: Wireless remote temperature sensing thermostat with adjustable register
Inventor: TANG LE D
IPC: F24F11/00
Filed: 1998-07-27
Granted: 2000-10-03
Abstract: A wireless remote temperature sensing and control thermostat system for regulating air ducted air conditioning systems incorporating a normal mode and a remote control mode, including a combination thermostat and radio-frequency receiver unit, a radio-frequency transmitter, and an adjustable register. In the normal mode, a reference temperature is set by the thermostat for the temperature throughout the entire air-conditioned structure. In the remote control mode, the local temperature sensing and control functions of the thermostat are disabled and the transmitter unit will take over the temperature sensing at the remote site which, in turn, then will control the thermostat unit. As a result, the users will be able to more accurately control their own personal environment.

Title: Earphone-microphone system having double ear braces
Inventor: YANG BILL
IPC: H04R1/10
Filed: 1999-05-18
Granted: 2001-08-14
Abstract: An earphone-microphone set that has a pair of adjustable ear braces. The earphone-microphone set includes an earphone housing for enclosing the earphone. There is a shallow groove around the outer edge of the housing and a cable latch positioned vertically at each end of the groove. A hole is also drilled beside each of the cable latch. A microphone capable of rotating is attached to the earphone housing. One end of a signal transmission cable is connected to the earphone. The cable comes out from the edge of the earphone housing around its mid-section. The other end of the cable is connected to a plug. An upper ear-brace-adjusting pin and a lower ear-brace-adjusting pin are inserted into the respective upper circular hole and the lower circular hole beside the cable latches. The upper and the lower ear-brace-adjusting pin also passes through an upper ear brace and a lower ear brace so that each ear brace can slide up or down independently. Consequently, distance of separation between the two braces can be adjusted to fit whatever ear size a user may have.
