Abstract: An anchor system for a hollow wall or ceiling includes an anchor including a penetrating portion (24) which has a fixed sleeve (28) and a pivoting locking leg (30) connected to the fixed sleeve by a hinge (32). The fixed sleeve has a non- round opening (34). The pivoting locking leg has a stub (38) to retain the penetrating portion rigid as the anchor (12) is inserted to the wall (W). A pin portion (14) has a body including a flexible shaft (20) and an actuating element (46) extending transversely from an end of the shaft. The actuating element has a heel (60) at about a rear surface (52) thereof. When the pin is inserted into the opening, the actuating portion contacts the stub to separate the pivoting locking leg from the fixed sleeve portion and to pivot the pivoting locking leg portion toward an inner surface (S) of the wall. Rotating the pin engages the actuating element at the heel with the stub to lock the leg in place and the shaft flexes to accomodate rotation of the leg more than or less than 90 degrees to secure the leg against the inner surface.

Abstract: Described herein is a process that employs heat, derived from the combustion of product cleaning streams, such as waste streams, in a solvent-based extraction process. Solvent extraction of bitumen generally involves combining solvent with a bituminous feed to produce a cleaned bitumen product. Solvent is recovered, for example by utilizing heat to cause evaporation, and recovered solvent may be re-used. In an exemplary embodiment, hot flue gas from waste stream combustion may provide the heat to evaporate the solvent. Product cleaning waste streams may be ones produced from the trim cleaning of solvent extracted bitumen or from treatment of bitumen froth produced in a water-based extraction process. The heat generated can contribute to the energy requirements of the overall solvent extraction of bitumen.

Abstract: A system and method for managing a route cache to reduce the risk of disruption from denial of service attacks. All traffic arriving on a front interface from local (on-link) nodes (e.g., neighbor nodes) can be treated normally. However, for packets arriving from remote (off-link) sources addressed to a given destination IP address, a single, shared route cache entry can be used. The source-address field in this entry can be zeroed-out since it will not be used for traffic coming from any one source. Similarly, for all packets going to off-link destinations through the front-interface, another single shared route cache entry can be created and used. The destination-address field in this entry can be zeroed out since it will not be used for traffic going to any one destination.
