Title: Drilling with casing
Inventor: GALLOWAY GREGORY GUY
IPC: E21B7/20
Filed: 2003-12-19
Abstract: A method of drilling a wellbore with a casing involves placing a string of casing 150 with a drill bit 125 at the lower end thereof into a previously formed wellbore and urging the string of casing axially downward to form a new section of wellbore. Fluid is pumped through the string of casing into an annulus formed between the casing string and the new section of wellbore. There is also means for diverting a portion of the fluid into an upper annulus in the previously formed wellbore. The flow is diverted by a flow apparatus 200 and/or an auxiliary flow tube 205. The flow through these diverters may be controlled. This increases the carrying capacity of the circulation fluid without damaging wellbore formations.

Title: Engine internal gas transfer method
Inventor: MA THOMAS TSOI-HEI
IPC: F02M25/07
Filed: 2004-07-09
Abstract: An internal gas transfer method for operating an engine with at least a first and a second intake port controlled by respective first and second poppet valves normally timed to open and close during the intake period of the engine cycle. Variable valve timing is provided for at least the second poppet valve, and a non-return valve is mounted in the second intake port positioned such that the valve automatically shuts in the flow direction away from the engine cylinder when the said port and the non-return valve are subjected to a pressure higher than the intake air supply pressure.

Title: Mechanism for estimating and controlling di/dt induced power supply voltage variations
Inventor: GROCHOWSKI EDWARD T
IPC: G06F1/26
Filed: 2002-12-11
Abstract: A processor core 710 draws power from a supply network 780 according to the instructions it executes. A monitor unit 730 tracks the current drawn on successive clock cycles, and estimates the voltage seen by the core by filtering a sequence of current values according to the response function of the network. If the estimated core voltage is found to be outside a specified voltage range a throttle unit (fig 8A, 830) may adjust operation of the processor core in response. Processor core 710 may include selectively activated multiple pipeline units 724 whose activities are monitored to estimate current on a given clock cycle, and successive current values may be stored in a shift register (fig 8B, 824) and added using weight units (fig 8B, 850) appropriate to the response of the network, to estimate the processor voltage. Filtering may be by a finite impulse response filter (FIR) or a recursive infinite impulse response filter (IIR).

Title: Coating of surgical devices
Inventor: HALLETT MARTIN DAVID
IPC: B05D1/06
Filed: 2004-08-05
Abstract: The invention provides a method for the coating of a surgical device, wherein the coating is carried out by electrostatic Powder deposition. The device may be a device used in a surgical or diagnostic procedure, including interventional devices as well as implantable devices. Because the coating is applied electrostatically, it is attracted to all parts of the device, not just those parts that are in the 'line of sight' of the spray, as is the case with conventional liquid spray coating. The process allows uniform and reproducible amounts to be deposited and thus drug-eluting coatings can be accurately applied to stents and other surgical devices, resulting in good control over drug release. Furthermore, drug-eluting coats can be applied in a single step, although multiple layers can easily be applied if desired to create a specific drug release profile.
