Patent NO-996007-D0 (NO)
Inventor: ROBERTS MARK JULIAN
IPC: F25J1/00
Filed: 1999-12-07
Abstract: A pressurised gas (102), especially natural gas is liquefied using high and low level heat exchangers (104, 122) in each of which is provided by a respective mixed refrigerant (110, 124) which is vaporised at a respective essentially constant pressure. The mixed refrigerant vapour (140) from the high level heat exchanger (404) is compressed in at least two stages of compression which generates an interstage compressed refrigerant. The interstage compressed refrigerant is cooled, partially condensed, and separated into an interstage refrigerant vapour and an interstage refrigerant liquid (144). The interstage refrigerant vapour is compressed to yield a further compressed refrigerant (146) which is cooled, condensed, optionally subcooled, and flashed (450) to provide the first vaporising mixed refrigerant (410) and the interstage liquid refrigerant (144) is subcooled and flashed (468) at the first essentially constant pressure to yield additional refrigeration in the first heat exchange zone (404). The process and apparatus of the invention are especially well-suited for installation on ships (including barges) and offshore platforms. <IMAGE>

Patent GB-0124326-D0 (GB)
Title: Overflow chamber
IPC: E03F5/10
Filed: 2001-10-10
Abstract: An overflow chamber ( 2 ) is provided for use in a combined sewer overflow. An inlet ( 12 ) and an outlet ( 14 ) open into the chamber ( 2 ) below a screen ( 20 ), and an overflow outlet ( 15 ) opens into the chamber above the screen. Baffles ( 26 ) are provided underneath the screen ( 20 ) across the general flow of storm water. In storm conditions, the storm water in the chamber ( 2 ) will reach the level of the screen ( 20 ), which traps aesthetically offensive material and gross solids, leaving the water to flow through the screen ( 20 ) to the overflow outlet ( 15 ). The baffles ( 26 ) circulate the storm water, and this dislodges material accumulated on the underside of the screen ( 20 ) and so helps to prevent blinding of the screen ( 20 ) in storm conditions.
Patent GB-0206094-D0 (GB)
Title: Symmetric key cryptosystem
IPC: H04L9/26
Filed: 2002-03-15
Abstract: A symmetric (shared key) key encryption system which encodes message data using an algorithm, a secret key(1) and a random initial message(5) and a matching decryption system which decodes encrypted data using an algorithm and the same secret key(1). The system uses an irreversible function and a random initial message(5) to obscure the key(1) from cryptographic analysis, resulting in a system with a high level of data confidentiality at the same time as low resource utilisation and high speed operation. Confidentiality is further enhanced by the essentially linear relationship between key length and the product of resource utilisation and processing time per unit message data, allowing the system architect to select a longer key length without disproportionate increase in complexity or power consumption or decrease in speed.

Title: Heat generating shoes
IPC: A43B3/35
Filed: 2004-12-10
Abstract: Footwear that has a generator that generates electricity from the walking action of the wearer, the electricity is then converted into heat. Preferably the generator is located in the heel of the footwear.
