Patent CA-2252775-A1 (CA)
Inventor: ROBINSON NIALL A
IPC: H04B10/2569
Filed: 1998-02-25
Abstract: Un séparateur de faisceau de polarisation permet de séparer des signaux de données optiques en premiers et deuxièmes signaux optiques à polarisation orthogonale. Un premier élément de temps de propagation variable constitue un premier temps de propagation incrémentiel au premier signal optique polarisé. Un deuxième élément de temps de propagation variable constitue un deuxième temps de propagation incrémentiel au deuxième signal optique polarisé. Le premier et le deuxième élément de temps de propagation variable consistent en une série de commutations optiques interconnectées optiquement par différentes longueurs de fibre optique incrémentielles différentes. Par exemple, 2 x 2 commutations optiques sont prévues pour une commutation entre un segment de fibre de référence et un segment de fibre de temps de propagation respectif afin de fournir un temps de propagation incrémentiel relatif. Un organe de commande permet de commander des signaux optiques dans les premiers et deuxièmes éléments de temps de commutation variables pour déterminer des premiers et des deuxièmes temps de propagation incrémentiels. En particulier, les premiers et deuxièmes signaux optiques polarisés sont retardés de façon incrémentielle les uns par rapport aux autres, de manière à compenser une dispersion de mode de polarisation. Un mélangeur de faisceaux permet ensuite de combiner les premiers et deuxièmes signaux pour former un signal de données de sortie optique pouvant être détecté précisément par un récepteur sans les effets dus à la dispersion de mode de polarisation. De cette manière, il est possible de transmettre des signaux de données optiques de façon fiable sur de grandes distances le long d'un support dispersif à fibres optiques longue distance à des débits binaires plus élevés et sur de plus grandes largeurs de bande.

Patent CA-2259831-A1 (CA)
Title: Backflow valve
Inventor: MCGARRAH ROBERT G
IPC: F16K15/14
Filed: 1992-03-16
Abstract: A backflow valve for use in a post-mix carbonator system for preventing the backflow of carbonated fluid, thereby preventing the contamination of the fresh water supply, and indicating when such a backflow condition has occurred.  In a first embodiment the valve comprises a check seat body which houses an elastomeric valve member, and a sight glass body for viewing the position of the elastomeric valve member.  The valve also comprises top and base connectors for connecting the valve to the fluid carrying line and a shut-off/flush valve for controlling the flow of fluid through the device.  The elastomeric valve member allows the flow of fluid from the supply to the outlet when the fluid pressure at the supply exceeds the pressure at the outlet and prevents the reverse flow of fluid when the pressure at the outlet exceeds the pressure at the supply. As the pressure downstream increases, the elastomeric valve member is forced in the upstream direction over a plurality of steps in the check seat body.  As the elastomeric valve member passes over each step, it engages the step and is thereby prevented from moving downstream.  The position of the elastomeric valve member may be observed through a sight glass body which has a line marking the normal position of the elastomeric valve member.  In a second embodiment the elastomeric valve member is slidably disposed within a retaining chamber that is positioned between the upstream and downstream portions of the valve.  Under normal operating conditions, the elastomeric valve member is in a normal first position allowing fluid flow therethrough; however, in a backflow condition, the elastomeric valve member slides into a second position within the retaining chamber and fluid flow is restricted.  In addition, once the elastomeric valve member is in the second position, it is secured in place and a backflow condition is thereby indicated.

Title: Pneumatic nailer including safety trigger for disabling/enabling operation
Inventor: BROWN RANDY M
IPC: B25C1/04
Filed: 1999-02-09
Abstract: A pneumatic nailer having a safety mechanism that reduces accidental discharge of nailer is provided. The nailer includes a hollow main body housing having a main pressure chamber in pneumatic communication with a main valve housing. Pressurized gas is injected into main pressure chamber, and a metering hole between the main chamber and valve assembly allows gas pressure to equalize between the main chamber and the valve housing. A safety trigger and safety valve are in pneumatic communication with the pressurized valve housing. A ram cap positioned over the top portion of the valve assembly is struck, moving the main valve assembly downward, with unseating of a cylinder firing valve only if internal pressures have been adjusted by actuation of the safety valve by an operator. When safety valve is actuated, gas pressure drops in the valve housing, reducing pressure on the main valve side of cylinder firing valve, allowing movement of main valve and cylinder firing valve, while gas pressure flows into piston cylinder, moving downward the piston and driver blade assembly, and forcing ejection of a fastener from nailer. If safety trigger is not actuated, pressure remains constant around main valve and cylinder firing valve, remaining closed, and negating upward movement of cylinder firing valve with no movement of piston and driver blade assembly, despite striking of ram cap. Thus, the possibility of accidentally driving a fastener is virtually eliminated without operator's use of the safety trigger.
