Abstract: A process is disclosed to authenticate subscribers to one or several exchanges of a digital communications network, with at least one subscriber-side network terminator, to which at least one data terminal can be connected, at least one authentication module arranged at a subscriber, which module can receive a first identification carrier containing a first subscriber-specific cryptographic key and at least one second authentication module at or immediately upstream from the exchange that can receive a second identification carrier containing a second subscriber-specific cryptographic key, with the following process steps: a) transmission of information sent from the second authentication module to the first authentication module, b) encoding of the information received with the first subscriber-specific cryptographic key in the first authentication module, and transmission of the coded information back to the second authentication module, c) decoding of information with the first subscriber-specific cryptographic key in the second authentication module with a second subscriber-specific cryptographic key to authenticate the subscriber to the exchange. For that purpose, a device for authenticating subscribers to one or several exchanges of a digital communications network has at least one subscriber network termination to which at least one data terminal may be connected. The invention is characterised in that at least one first authentication module is provided for each subscriber and can receive a first identification carrier, and in that at least one second authentication module that can receive a second identification carrier is provided at the exchange.

Title: The maharaj cushion
Inventor: MAHARAJ SUDARSHAN
IPC: A63B59/70
Filed: 1998-06-23
Abstract: The ice hockey goaltender's stick is known to be comprised of wood or other composite materials approved by the National Hockey League Rules Committee. The widened portion of the goalkeeper's stick is known to be coated in fibreglass or other laminating materials to aid in the durability and decoration of the stick. Current trends in goaltending styles have resulted in the placement of the widened portion of the stick along the ice in a horizontal manner with increased frequency. In this invention, one or more impact absorbing materials are incorporated into and/or on the surface of the widened portion of the goal stick to absorb the amount of rebound that the puck demonstrates when contacting this area. The cushioning materials may extend from the top of the widened portion of the stick to the heel of the stick blade. The cushioning materials may occur on one or both sides of the widened area of the goaltender's stick.

Patent CA-2252754-A1 (CA)
Title: Method for improving the accuracy of machines
Inventor: GREENWOOD THOMAS A
IPC: B23Q15/18
Filed: 1997-06-03
Abstract: Large machines, especially those having working envelopes in excess of fifteen feet, exhibit unacceptable errors because of thermal expansion and mechanical misalignments between the axes. The errors have traditionally been minimized by enclosing the machine in a thermal enclosure, by careful calibration, or by mounting a laser interferometer on each axis. These solutions are costly, may require frequent recalibration, and do not correct for small rotations of one axis relative to another axis due to wear etc. The present invention uses an interferometric laser tracker or a comparable 3D position sensor to measure the position of a retroflector attached to the end effector, e.g. a machine head when the machine comes to rest. A computer compares the measured position to the desired position according to the machine media, and adds the appropriate correction with trickle feed media statements to move the machine to the correct position prior to further machining.

Abstract: Les présents inventeurs ont découvert que les êtres humains possèdent un gène qui code une nouvelle protéine de la famille des thymosines .beta.. Cette nouvelle protéine, appelée ici thymosine .beta.15, a la capacité de fixer et de séquestrer la G-actine, tout comme les autres membres de la famille des thymosines .beta., mais, à la différence de ce que l'on sait sur ces autres membres, cette nouvelle protéine a également le pouvoir de réguler directement la motilité cellulaire dans les cellules de carcinomes de la prostate. Un ADNc du gène de la thymosine .beta.15 humain (SEQ ID NO: 1) et ayant la séquence d'acides aminés déduite (SEQ ID NO: 2) a été isolé. Les présents inventeurs ont démontré que des produits de transcription améliorés (ARNm) et l'expression du gène de la thymosine .beta.15 dans des cellules non testiculaires ont une corrélation élevée avec des étapes pathologiques dans un grand nombre de cancers, tels que le cancer de la prostate, le cancer des poumons, le cancer avec mélanomes et le cancer du sein, en particulier les cancers avec métastases. Par conséquent, la découverte de niveaux accrus de produits de transcription ou de produits génétiques dans des tissus non testiculaires peut être utilisée non seulement à des fins de diagnostic mais également à des fins de pronostic dans des cancers particuliers.

Patent CA-2268649-A1 (CA)
Title: Surface densification of machine components made by powder metallurgy
Inventor: MANDEL JOEL H
IPC: C21D9/32
Filed: 1997-10-15
Abstract: A sintered powder metal part is surface densified by surface heating followed by repressing. Surface heating is preferably done to a temperature which is just below the critical temperature where the steel alloy material of the part transforms from a ferritic to an austenitic microstructure. Repressing is in a die set which is smaller than the part by 10 % of the surface heated depth. The hot skin is compressed and densified between the die and the cooler, and therefore less malleable core of the part. Following surface densification, the part may be resintered and/or heat treated.

Patent CA-2273745-A1 (CA)
Title: Fluid sterilization apparatus
Inventor: THORPE GEORGE W
IPC: C02F1/00
Filed: 1999-06-04
Abstract: Apparatus for treating water or other fluid with radiant energy from an ultraviolet lamp includes a helical shaped input fluid flow guide or helical ramp disposed at or near one end an elongated annular chamber around the lamp. The guide or ramp serves to impart input spiral flow momentum to the fluid upon entry to the chamber. A corresponding output fluid flow guide or helical ramp may be disposed at or near the opposed end of the chamber to impart output spiral flow momentum to the fluid as it approaches discharge from the chamber. Spiral flow serves to extend the time that the fluid is exposed to ultraviolet light and thereby increases the probability that any microbiological contaminants present in the fluid will be killed. The use helical shaped guides or ramps better serves to establish such a flow in circumstances where the available fluid pressure is relatively low.
