Title: Telecommunication System with Detection and Control of Packet Collisions
Inventor: PUNJ VIKRAM
IPC: H04L12/56
Filed: 1995-10-25
Abstract: Line cards provide an input/output interface between synchronous communication channels and an asynchronous network.  The input line card translates information received from the synchronous communication channels into packets for transmission to the asynchronous network.  Each line card generates and stores packets corresponding to a time frame associated with the synchronous communication channels, A sequence is selected for the sequential transmission of packets by each input line card to the asynchronous network.  The cumulative number of packet collisions that would occur at each output line card during the predetermined time frame is determined.  If the cumulative number of collisions exceeds a predetermined delay threshold, the number of packets actually transmitted to the system is reduced preferably by denying service to new call origination requests.  This technique keeps the maximum cumulative collisions for each output line card within the predetermined delay threshold.

Patent CA-2174981-A1 (CA)
Inventor: MAIWALD MARVIN ANTHONY
IPC: B62D21/14
Filed: 1996-04-25
Abstract: An agricultural sprayer suspension includes four generally identical independent strut suspension assemblies each having a pneumatic spring supported above a strut shaft which is received within a strut journal connected to an adjustable axle. A scissors assembly located above the axle maintains wheel steer while facilitating vertical movement of the strut shaft within the journal. On non-steerable wheels, the lower end of the scissors assembly is connected to the journal to maintain a preselected wheel orientation. For steerable wheels, the lower end of the scissors assembly is connected to a hydraulic steering structure which allows axle adjustments for varying wheel tread. Similar construction of the steerable and non-steerable wheel assemblies reduces the number of different parts required and facilitates selective construction of sprayers with either two-wheel or four-wheel steering. A centrally located cab and sloping hood structure provide good visibility and direct viewing of all four wheels.

Patent CA-2199454-A1 (CA)
Title: Flue gas desulfurization method and apparatus
Inventor: FARTHING GEORGE A
IPC: B01D53/50
Filed: 1997-03-07
Abstract: A combined furnace limestone injection and dry scrubber flue gas desulfurization (FGD) system collects solids from the flue gas stream in first particulate collection means located downstream of an outlet of a convection pass of the furnace and upstream of the dry scrubber. The collected solids are diverted to the dry scrubber feed slurry preparation system to increase sulfur oxide species removal efficiency and sorbent utilization. The level of lime in the feed slurry provided to the dry scrubber is thus increased, which enhances removal of sulfur oxide species in the dry scrubber. The decreased particulate loading to the dry scrubber helps maintain a desired degree of free moisture in the flue gas stream entering the dry scrubber, which enhances sulfur oxide species removal both in the dry scrubber and downstream particulate collector, normally a baghouse.

Abstract: Unité de travail servant à remplir une grille à globules de soudure et exploitant la pesanteur dans le but de transférer les globules de soudure entre une plaque de manoeuvre et la grille à globules. La plaque de manoeuvre est placée sur une monture conjointement avec un réservoir pour globules de soudure. Selon un mode de réalisation, on fait tourner la monture, la plaque de manoeuvre et le réservoir sur 180~ afin d'étaler les globules de soudure sur la plaque de manoeuvre et de ramasser les globules de soudure errants au cours de la rotation de la monture. Un cylindre monté mobile dans le sens vertical met une grille à globules en position juxtaposée avec la plaque de manoeuvre chargée de globules, et ce avant que cette plaque n'atteigne le point (angle de rotation) où la pesanteur provoque la chute des globules de soudure à partir de la plaque de manoeuvre. Lorsque la plaque poursuit sa rotation, les globules sont transférés, sous l'effet de la pesanteur, dans une grille à globules (enrobée). On a également prévu un appareil mettant en oeuvre plusieurs unités de travail de ce type.
