Patent CA-2196650-A1 (CA)
Inventor: WARRENDER NEIL ANDREW
IPC: C23F11/14
Filed: 1997-02-03
Abstract: A method for inhibiting corrosion of a surface of carbon steel exposed to an aqueous medium in which the method includes forming a layer having a corrosion-inhibiting amount of a quaternary pyridine salt and a water-immiscible organic component on the surface by incorporating into the medium a composition containing the salt, the organic component and a surfactant. The surfactant is present in the composition in an amount sufficient to solubilize a sufficient amount of the organic component in the aqueous medium so as to permit formation of the protective layer. The organic component is most often a hydrocarbon and can be a single hydrocarbon, but is more likely to be a mixture of hydrocarbons. The surfactant can be cationic, non-ionic, amphoteric or anionic.

Title: Pump sprayer for viscous or solids laden liquids
Inventor: EVANS STEPHEN FRANCIS
IPC: B05B15/02
Filed: 1996-05-03
Abstract: A hand holdable spray delivery system (10) for dispensing a relatively viscous and/or solids laden liquid is provided. This spray delivery system (10) includes a container (30) adapted to house the liquid. A manually actuated pump device (20) is mounted on the container (30). The pump device (20) including an inlet passage (23), a pump chamber (28), and a discharge passage (27) having a distal end connected in liquid communication so that the liquid is pumped from within the container (30), through the inlet passage (23), into the pump chamber (28) and through the discharge passage (27) upon manual actuation of the pump device (20). A slotted spray nozzle (40) including a housing (55) having an inlet side (46) and an exit side (44) is also included.  The housing (55) having an internal recess (45) through the inlet side (46) that terminates in an elongated orifice (42) at the exit side (48). The internal recess (45) being attached in liquid communication to the distal end of the discharge passage (27) such that the liquid passing through the discharge passage (27) flows through the slotted spray nozzle (40) and converges toward the elongated orifice (42). The liquid is dispensed therefrom in a dispersed spray. The slotted spray nozzle (40) can be made of a rigid material or an elastomeric material. A fan shaped dispersed spray pattern is generated when the nozzle (40) is made using a rigid material, however, when an elastomeric material is utilized, the nozzle (40) is capable of ejecting particles larger than the smallest dimension of the elongated orifice (42), thereby substantially reducing the likelihood of clogging. Several versions of the spray delivery system (10) are illustrated, including a trigger operated sprayer and a reciprocating finger pump (20).

Patent CA-2237208-A1 (CA)
Title: Congestion notification from router
Inventor: HADI SALIM JAMAL
IPC: H04L47/27
Filed: 1998-05-08
Abstract: In a muter in a network comprising a source node, and a receiver node, and other nodes, a congestion monitor determines a degree of congestion, which is sent back to the source node, using an OSI network layer protocol. This enables the flow of packets from the source to be controlled more accurately to maintain high throughput with reduced probability of congestion. Using the network layer rather than lower layers can ensure the indication can be carried across the entire network, and not be lost at boundaries between data links making up the network.
