Title: Method and system for densifying liquid methane using a liquid nitrogen bath
Inventor: NGUYEN HAN V
IPC: C10L3/00
Filed: 2010-06-30
Abstract: A method and apparatus 10 for densifying liquid methane is described. The method includes passing the liquid methane through a liquid nitrogen bath 14, self-pressurizing a container 62 associated with the liquid nitrogen bath through boil off of the liquid nitrogen within the container, and regulating pressure within the liquid nitrogen container to maintain a boiling point of the liquid nitrogen above the triple point temperature of the liquid methane passing through the liquid nitrogen bath.

Patent GB-2485563-A (GB)
Title: Non-round introducer assembly
Inventor: RASMUSSEN ERIK
IPC: A61M25/00
Filed: 2010-11-18
Abstract: An introducer assembly (10) e.g. catheter, is provided with a sheath (12) and carrier element (20). The sheath (12) is oval in axial cross-section and has an oval internal wall (24). The carrier element (20) has an outer wall (22) which is oval and which has a shape corresponding to the shape of the internal wall (24) of the sheath (12). The non-round shapes of the sheath (12) carrier element (20) extend the whole length of the introducer (10). This structure ensures that the sheath (12) and carrier element (20) cannot rotate relative to one another during deployment of the assembly (10). Thus, any medical device e.g. stent, carried on the introducer assembly (10) will not be subjected to any relative rotation of the sheath (12) and the carrier element (20). This ensures that the integrity of the medical device is retained. The structure also increases the torque strength of the assembly (10), as well as providing the ability for the introducer assembly (10) to self-orient within the lumen of a patient. This can be particularly advantageous in the deployment of medical devices or instruments which are rotationally dependent. In another aspect a method of manufacture is described.

Title: A combiner filter to allow multiple BTSs operating in a common frequency band to share a common antenna
Inventor: GOSTLING MARTIN JOHN
IPC: H03H7/46
Filed: 2011-06-10
Abstract: The invention addresses the problem of allowing a first operators    base transceiver station (BTS) to share an antenna with a second operators    BTS when both operators are using the same frequency band, but different sub-bands of the frequency band. This is achieved by interposing a first filtering means between the antenna and the BTS of the first operator, and a second filtering means between the antenna and the BTS of the second operator. Each filtering means includes two bandpass filters (41, 43 or 45, 47) connected in parallel. Each filtering means passes two non-contiguous portions of the frequency band. For example the first filtering means could pass 33 the lowest frequency receive sub-band and a first transmit sub-band which lies above another receive sub-band blocked by the first filtering means.

Title: Determining pressure profile in an oil or gas well
Inventor: WATLEY DANIEL ANDREW
IPC: G01B11/00
Filed: 2011-06-21
Abstract: A method for use in determining pressure comprises configuring first and second strain sensors to sense respective strain signals along a common direction in a carrier member, the first and second strain sensors having a different response to pressure exerted on the carrier member. The sensors comprise a central optical fibre 34 and four peripheral optical fibres 36,38,40,42. Each optical fibre is coupled to a strain interrogation system (60 to 68, figure 1) and each system includes a pulsed laser source (70) coupled via an optical coupler (72) to the appropriate optical fibre and an optical detector (74) for monitoring power transmitted by the pulsed laser source (70).Â  The method further comprises determining a pressure from the respective strain signals sensed using the first and second strain sensors. Such a method may permit the effects of pressure exerted on the carrier member to be distinguished from the effects of mechanically-induced strain exerted on the carrier member thus allowing a pressure to be determined. Such a method may be particularly useful for providing a distributed pressure profile in a remote or hostile environment such as a subterranean or subsea oil or gas well.
