Abstract: An optical fiber cable assembly comprising an optical fiber slidably enclosed within a hollow tubing, both the fiber and the tubing having corresponding first and second ends. The cable is terminated with the first and second ends of the tubing and the fiber constrained with respect to each other such that fiber and the tubing are approximately the same length when the cable is at a first temperature. The tubing is made of a material which contracts more than the optical fiber when the cable is exposed to temperatures below the first temperature, such that the fiber is longer than the tubing and excess fiber length is formed. An intermediate portion of the tubing permits the excess fiber length to accumulate without bending in a radius smaller than a minimum bend radius.

Patent CA-2548293-A1 (CA)
Title: Crosslinked polymer
Inventor: JING NAIYONG
IPC: C08J3/24
Filed: 2004-11-16
Abstract: A method is provided for obtaining crosslinked polymers, particularly fluorinated polymers having pendent sulfonic acid groups, by crosslinking through pendent groups, which include a sulfonyl chloride group (-SO2Cl). The sulfonyl chloride group may be removed by application of electromagnetic radiation, typically in the ultraviolet band, or a radical initiator, leaving behind a radical which readily binds covalently to other polymer strands or to crosslinking agents to form crosslinks. Typically, the polymer is made by providing a polymer comprising pendent groups which include a group according to the formula -SO2F and converting at least a portion of the -SO2F groups to -SO2Cl. After crosslinking, the remaining SO2F groups may be converted to sulfonic acid groups, yielding a crosslinked polymer electrolyte. Such crosslinked polymer electrolytes may be used to make polymer electrolyte membranes (PEM's) that may be used in electrolytic cells such as fuel cells.

Title: Preventing network data injection attacks
Inventor: STEWART RANDALL
IPC: G06F15/173
Filed: 2005-01-11
Abstract: Approaches for preventing TCP data injection attacks in packet-switched networks are disclosed. A first approach provides for dropping received segments that carry ACK values smaller than the next unacknowledged sequence number expected minus the maximum window size. This approach helps keep spurious injected segments out of the TCP re-assembly buffer. In a second approach, heuristics are used to examine the sequence number of a newly arrived segment, and when the sequence number is the next expected, then the newly arrived segment is used and the contents of the re-assembly buffer are not considered. Further, if the data payload of the newly arrived segment overlaps in sequential order with segments already in the re-assembly buffer, the overlapped segments in the re-assembly buffer are considered spurious and are discarded. Thus, this approach helps remove spurious data from the re-assembly buffer if the first approach somehow fails to prevent the data from entering the re-assembly buffer.

Title: Sorbent for removal of trace hazardous air pollutants from combustion flue gas and preparation method thereof
Inventor: RYU CHONG KUL
IPC: B01D53/64
Filed: 2006-08-30
Abstract: Disclosed is a sorbent for the removal of mercury from combustion flue gas and a preparation method thereof. The sorbent includes an activated heavy oil heavy ash impregnated with 0.1-30% by weight of any chemical substance selected from sulfur, iodine, bromine and chlorine. The sorbent is prepared in an economical manner using heavy oil fly ash, industrial waste generated from heavy oil-fired boilers, and has excellent sorption performance for mercury, so that a low concentration of mercury contained in combustion flue gas discharged from large-scale boilers can be removed by injection of a small amount of the sorbent. Thus, the invention can prevent a reduction in the recycling rate of coal fly ash in coal-fired power plants and minimize operation cost.

Abstract: The invention relates to a device for protecting the human body from the effects of acceleration such as those occurring in high-performance planes during changes of direction during flying. The cuffs (1), which can be shortened with the aid of liquid media, are hydrostatically pressurized. The liquid column is formed by means of flexible tubes (2) and a fluid reservoir arranged at the top. Three cuffs (1) are provided; two encompass the thighs and one surrounds the waist of the wearer. The cuffs (1) are integrated into an underwear suit (4). The cuff (1) around the waist can, for instance, be opened by means of a buckle above a zip fastener (6) for the purpose of putting on and taking off . The close-fitting cuffs (1) with a shortenable inner periphery cut the lower body area off from critical Gz acceleration forces when they occur and thus prevent blood from flowing to lower body parts. As a result it is possible to reduce the speed at which blood pressure falls at the level of the head, which is responsible for the provision of oxygen, thereby preventing a lack of consciousness caused by the force Gz. The cuff (1) can also be operated with compressed air.
