Title: De-icing a recondenser of a superconducting magnet
Inventor: MANGANO ROY A
IPC: F25D21/08
Filed: 2005-03-02
Abstract: An arrangement for de-icing a recondensing flow loop system (76) includes at least one resistive heating element (106) configured to melt iced particles (122, 124, 126) from the recondensing flow loop system (76). A power delivery circuit (112) delivers power from a power source (110) to the at least one heating element (106) in order to heat and melt ice at positions where ice particles accumulate most often. A cooling system (70) for an MR superconducting magnet (54) comprises a liquid helium bath (72) having the recondenser flow loop system (76). The gaseous helium (78) which boils off from the helium bath (72) escapes from a magnet helium vessel (80) through a supply tube (82) that leads to a recondenser (84). The recondenser cools the gaseous helium and returns liquid helium through a delivery tube (86). In the event of a pressure surge in the vessel (80), a pressure relief valve (90) opens allowing helium gas to flow through an auxiliary cooling loop (92). Once an increase in pressure is detected, the recondenser de-icing system (100) which includes a vacuum pump (108) may be utilised to remove any ice build-up in the cooling loop (76). When a vacuum valve (102) is opened, the auxiliary cooling loop (92) is subjected to vacuum from the pump (108). The heating elements (106a-c) warm the ice formed in the cooling loop (76), with the vacuum pump (108) removing the molecules of melted ice. As the ice clears, the vacuum valve (102) is closed.

Title: Compiled document type definition verifier
Inventor: VESELOV PAWEL S
IPC: G06F9/44
Filed: 2005-03-17
Abstract: Provided is a method and an apparatus to verify an eXtensible Markup Language (XML) document against a compiled Document Type Definition (DTD). A DTD document can specify valid elements and the sequence of the valid elements in the XML document. During compilation, the elements of the DTD document are added to a structure, such as a tree. Consequently, nodes in the tree can contain elements, which are verified against the elements in the XML document. If there is a match between all the elements in the XML document and elements of the structure, then the XML document is valid. A valid XML document is thus verified and can be processed. Otherwise, an error can result, indicating an invalid XML document.

The channel waveguides (3) are formed such that differences in light path length between adjacent ones are equal to each other. An output slab (4) condenses the split light components from the channel waveguides (3). Portions of the channel waveguides may be positioned along an arc in the input slab (2). This arc is centred on diffusion centre (21).

Title: Encrypted electronic mail messaging system
Inventor: DANCER ANDREW
IPC: H04L12/58
Filed: 2006-04-03
Abstract: An electronic messaging system in which a plurality of user computers are connected to a mail registration server 7 via the internet. The mail registration server stores plural sets of decryption data (decryption keys) each set being required to decrypt a corresponding encrypted electronic message. Following receipt of an encrypted electronic mail message a user computer (recipient) communicates with the mail registration server to effect decryption of the encrypted electronic mail message using the corresponding decryption data stored by the mail registration server. This may involve authentication of the recipient to the mail registration server (for example using a digital signature) and release of the corresponding decryption key to the recipient if authentication is successful. In this way, accessing of the electronic mail message can be monitored (tracked) by the mail registration server, such as by providing an access report (or decryption key request report) to the encrypted mail message sender 89. The system may further use identifier-based encryption (IBE) techniques (for example using the recipient's email address, or derivative thereof, as the encryption key). The system may further use session keys in a KEM-DEM arrangement.

Title: Solar heat engine comprising a turbine driving a compressor
Inventor: STREVENS CHRISTOPHER JOHN RALP
IPC: F24S10/75
Filed: 2006-08-29
Abstract: A solar heat engine comprises a solar heat collector, a radiator, an insulator, and a turbine driving a compressor. The solar heat collector comprises a thin walled copper tube AB and the radiator comprises a thin walled copper tube CD. Each of the tubes includes a number of heating or cooling fins made from thin copper sheet. An insulator is provided between the solar heat collector and the radiator so as to place the radiator's cooling fins in a region of shadow or shade. A working fluid, such as ammonia gas, is heated in the solar heat collector between points A and B. The warmed working fluid then passes through the turbine (B-C, fig.2) and into the radiator where low grade heat is rejected between points C and D. The cooled working fluid then passes through the compressor (D-A, fig.2) before returning to the solar heat collector at point A. In operation, the solar heat collector is heated by the sun as it arcs overhead during the day whilst the radiator's shaded cooling fins dissipate heat to the air. Power may be taken from the turbine to drive machinery or to generate electricity.
