Abstract: Ammunition for a small-bore weapon operable in the semi-automatic or automatic mode. A round of the ammunition includes a combination of case (12), powder (28) and projectile (24) which enables the projectile to be propelled at subsonic velocity from the weapon to a target while generating sufficient energy to consistently operate the bolt of the weapon and which generates substantially no audible sound during its free flight through air. The projectile (24) of the ammunition is formed from a core (25) including multiple elements (40, 46), each of which is formed from a mixture of heavy metal powder and light metal powder that is densified under high pressure to provide enhanced density of the elements, hence of the core. These elements are incorporated into a light metal jacket (52) by high pressure. A method for the manufacture of the projectile is disclosed.

Title: Rubber laminated bearing-seal for a shaft penetrating a pressure vessel
Inventor: HINKS WILLIAM L
IPC: F16J15/50
Filed: 2000-03-13
Abstract: At least one rubber laminated bearing-seal, consisting of multiple flat or curved alternate laminations of metal and rubber bonded together and having an aperture, is seated in a complementally-configured apertured receptacle in the wall of a pressure vessel and supports and seals a shaft that penetrates said apertures and extends through the wall. Shear strains in the rubber laminations permit the shaft to carry limited movements through the wall while the laminations seal against any flow of the liquid or gaseous medium on one side toward the other and withstand the resulting thrust caused by large pressure differences. The torque reaction of this bearing-seal is essentially proportional to rotation angle. A potential use is in the intense undersea hydrostatic pressure environment at great depths, carrying limited motion through the hull of a submersible craft. Safety backup against seal failure is provided.

IPC: H04L1/00
Filed: 1998-10-22
Abstract: On utilise un code en treillis variant dans le temps pour obtenir la vitesse de codage souhaitée, de manière à produire une sortie codeur pouvant être directement mise en correspondance avec une constellation de signaux. On peut obtenir ce code en treillis variant dans le temps en utilisant un codeur à vitesse variable, destiné à produire, à sa sortie, le nombre adéquat de bits, ce qui permet de mettre directement en correspondance ce code et la constellation de signaux voulue. Le flux de données entrées est alors codé selon une première vitesse de codage pendant un premier intervalle de temps, puis selon une deuxième vitesse de codage pendant un second intervalle de temps. En modifiant cette vitesse de codage à intervalles périodiques, on obtient une troisième vitesse de codage plus efficace.

Title: Data compression negotiation in a telecommunication system
Inventor: RASANEN JUHA
IPC: H04W92/02
Filed: 1998-11-23
Abstract: The invention relates to a method for setting up a data link, wherein an end-to-end link comprises at least two separate legs (402, 403) with error correction protocols. The legs may have different physical layer connections or their error correction protocols (V. 120, RLP) may be different. An interworking function IWF according to the invention that is located between these legs (402, 403) is integrated such that the legs can communicate with each other during set-up of traffic channel in order to exchange data compression parameters.  The IWF intervenes in an end-to-end data compression negotiation, performs protocol conversions on messages transmitted from one leg to another, synchronizes the legs, if required, by delaying the set-up of the faster leg and the compression negotiation, modifies the compression parameters provided by the legs, if required, and if the end-to-end data compression negotiation fails, it may set up data compression on only one leg.

Patent CA-2313677-A1 (CA)
Inventor: HAAG DAVID K
IPC: H01H9/26
Filed: 2000-07-10
Abstract: An apparatus for interlocking horizontally adjacent first and second circuit breakers and preventing the circuit breakers from simultaneously being in a closed operating position. The circuit breakers each have a pivotable actuating handle movable between a closed position which is proximal to the other circuit breaker, and a open position which is distal to the other circuit breaker. A housing lies between the first and second circuit breakers and an interlock bar is slidably retained in the housing. In operation, the interlock bar is slidable between a first position where the interlock bar prevents the first circuit breaker handle from pivoting into the closed position and a second position where the interlock bar prevents the second circuit breaker handle from pivoting into the closed position. If the interlock bar is in the first position and the handle of the second circuit breaker is in the closed position, the handle of the second circuit breaker prevents the interlock bar from being moved into the second position. To move the interlock bar into the second position, the user must move the handle of the second circuit breaker into the open position.  Once the handle of the second circuit breaker is in the open position, the interlock bar can be moved into the second position and the handle of the first circuit breaker may be closed. While the interlock bar is in the second position and the handle of the first circuit breaker is in the closed position, the handle of the first circuit breaker prevents the interlock bar from being moved into the first position.
