Title: Improved valve
Inventor: MCKAY FREDERICK DUGUID
IPC: E21B29/04
Filed: 2005-11-14
Abstract: An improved valve for sealing a wellbore and method of use, in particular for prevention of well blow outs. In one embodiment, the apparatus is designed to seal a well (11) through rotation of rams (15A, 15B). The rams may be actuated to seal the well (11) without having to work against full well pressure as fluid volumes in the apparatus housing (12), which also contains the rants (15A, 15B), are preserved. This functionality allows the apparatus to be constructed with smaller dimensions than existing prior art blow out prevention valves aiding handling and manoeuvrability. The improved valve according to one embodiment also has a mechanism that guides a wireline or a pipe being run in the wellbore to the centre of the bore and allows a seal to be formed around the wireline or pipe.

Title: A scan pulse shift register for an active matrix LCD display
Inventor: JOHN GARETH
IPC: G09G3/36
Filed: 2007-08-30
Abstract: The stages of a scan pulse shift register are activated in sequence during normal operation to output a high level via transistor 56 on one stage output GL in turn. Each stage comprises a logic circuit 34 controlling the output transistors 56,58. The transistor 58, which is conventionally connected to a low logic level, is connected to a signal ALLON which is low in normal operation but which may be placed at a high level so that the output GL of any stage to which ALLON is connected is made high instead of low. This simple adaptation allows all rows in the display, or all rows in a portion of the display, to be activated simultaneously, for example to remove charge from the pixels and prevent noise on the display. The logic circuit may comprise a reset-over-set flip-flop. The bootstrap capacitors 64,74 improve the output high level.

Title: Microprocessor-controlled bias adjustment in a thermionic valve audio amplifier
Inventor: ARROWSMITH COLIN
IPC: H03F1/04
Filed: 2008-08-06
Abstract: The grid bias for the thermionic valves in a push-pull audio amplifier output stage is adjusted by a microprocessor in dependence on the cathode currents as sensed by small resistors.
