Title: Energy curable cyclic carbonate compositions
Inventor: HERLIHY SHAUN LAWRENCE
IPC: C08F18/24
Filed: 2005-11-14
Abstract: An energy curable composition contains a polyfunctional cyclic carbonate, a monomer or oligomer copolymerisable with the cyclic carbonate, and a cationic photoinitiator. Suitable carbonates include epoxidised soya bean oil carbonate and epoxidised linseed oil carbonate. Alternatively, the carbonate may be a polymeric compound in which the carbonate groups may be pendant to or located in the main polymer chain, e.g. polyvinylidene carbonate. Typically, the copolymerisable monomer or oligomer comprises an epoxide and/or an oxetane. The photoinitiator may be selected from sulphonium, thianthrenium, iodonium, phenacyl sulphonium, and thioxanthonium salts. The composition preferably contains 1-50 wt.% of the carbonate based on the total weight of the polymerisable components. The composition may be formulated as a printing ink, varnish, or adhesive and may comprise a colorant. Also disclosed is a method, whereby the composition is applied to a substrate before being cured by exposure to energy, especially ultraviolet radiation.

Title: Adaptive regulation of current and voltage peaks by chopped gate drive adjustment
Inventor: MADATHIL SHANKAR N EKKANATH
IPC: H03K17/082
Filed: 2006-08-11
Abstract: The gate drive signal for an IGBT 20 is pulse-width-modulated at high frequency (20 MHz) during turn-on and turn-off to allow control of the gate drive strength. Reduction of gate drive reduces transient current peaks during turn-on and transient voltage peaks during turn-off. Measurements of deviations from the desired voltage and current peaks are fed back 22 to a mark-space controller 21 to allow adaptive adjustment of gate drive strength, which controls collector current rate of change (dIc/dt) and hence transient peak amplitudes. The switch control thus adapts automatically to any application. The gate drive circuit may be integrated into the same package as the IGBT.

Inventor: FONG NERIC
IPC: H03G1/00
Filed: 2006-11-17
Abstract: An RF variable gain amplifier with an extended linear gain control range is disclosed. The RF VGA (fig.5) consists of a core of two variable gain amplifiers 502, 504, a linear current control that provides control current to each amplifier 502, 504, and a linear-in-dB voltage to current converter 506. The RF VGA relies on the difference in transconductance (gm) between the two amplifiers to perform gain control. To provide an extended linear control range, each amplifier 502, 504 employs a employs a wide swing cascode mirror formed by two gain transistors M1, M2 and two cascode transistors M3, M4. The two cascode transistors track each other, as do the two gain transistors. The gain transistors operate in the saturation region. A current mirror biasing scheme is used (M5). The amplifier provides an accurate linear to decibel (linear-dB) gain control over a gain tuning range of 74dB as required, for example, in wideband code division multiple access (WCDMA) systems.

Abstract: The invention concerns a method for performing a repeated, i.e. four-dimensional, marine seismic survey. This includes towing at least one seismic source 15 behind a seismic survey vessel 10 substantially along the path of a previously conducted seismic survey, determining the position of the seismic source 15 during the repeated marine seismic survey, e.g. using GPS receivers mounted on seismic source arrays A, B, and comparing the determined position of the seismic source with a position of a seismic source recorded during a previously conducted seismic survey. The position of the at least one seismic source is adjusted in response to said comparison using a deflector 18 connected to the keel (bottom) of a buoy (float) 13 supporting each subarray A1, A2, A3, B1, B2, B3. A deflector control assembly (24, Fig. 2A) enables the angle of attack (22) between deflector 18 and buoy 13 to be varied by controlling an actuator arm (34). The invention may be performed in a manual or an automatic mode.

Abstract: A device (12) is disclosed which is for use in retrieving debris from a well. In one embodiment, the device includes an elongate body (20); a main bore (22) extending part way along a length of the body, along which fluid flows into the device; an opening (24) towards a lower end of the body; a main fluid chamber (28) in the body in fluid communication with the main bore; a flow restriction (30) provided in the main bore, through which fluid flows from the main bore and into the main fluid chamber; at least one chamber outlet (32) for directing fluid from the main fluid chamber into an annulus defined between the device and a well borehole wall; a return flow passage (40) extending between the body opening and the main fluid chamber, for return flow of fluid from the annulus to the main fluid chamber, to facilitate retrieval of debris from the well; and at least one fluid exit (44), for flow of fluid returned to the main fluid chamber through the return flow passage out of the device. In use, fluid flowing through the main bore is accelerated through the restriction such that the pressure of fluid exiting the restriction is lower than at a location upstream thereof, to draw part of the fluid returned to the main fluid chamber through the return flow passage into and through the chamber outlet, thereby recirculating said part of the fluid into the annulus. This assists in the retrieval of debris from the well.
