Patent CA-2110091-A1 (CA)
Inventor: OKANOUE YASUYO
IPC: H04L12/46
Filed: 1993-11-26
Abstract: A composite communication network of a hierarchical structure including a subnetwork at least in part thereof has a gateway (GW) node having a control message communication medium which includes three or more routes. Routing of the network layer level is performed between GW nodes and routing of the data link layer level is conducted in the ring subnetwork. Each node in the ring has an NE address to be distinguished in the ring and a routing table which shows a routing direction corresponding to a destination node. When the GW node in the ring including a target of a control message receives a message, the GW node sets an NE address of the target node in the packet of the message as a destination address, and processes the packet for transmitting to the control message communication medium indicated in the routing table. The node that receives the packet carries out mapping of the destination NE address of the packet and NE address of its own node by means of a routing application protocol of the data link layer level. When the two addresses coincide, the node transmits the packet to the internal message processor, but when they do not coincide, the node transmits the packet to a neighboring node and routing of the control message is performed with reference to the data link layer level in the ring subnetwork.

Title: Variable force die spring assembly
Inventor: FIDZIUKIEWICZ ERICH D
IPC: F16F1/32
Filed: 1994-08-30
Abstract: Abstract A variable force die spring is disclosed which combines high force, short axial compression distance spring assembly, such as belleville springs, and low force, high axial compression distance springs, such as coil springs, in a telescoping casing having an internal cavity.  The springs are arranged within the cavity so that upon receiving a load the low force spring will compress first resulting in a large axial compression and low force resistance.  The load applied to the telescoping casing will then transition from the low force spring to the high force spring.  The high force spring then compresses as the load continues to be applied.  In alternative embodiments, a third intermediate spring is added that compresses moderate distances under moderate pressure thereby increasing the overall axial compression and load capacity capabilities of the spring assembly.  In any embodiment, the invention results in a spring that provides high forces and low axial compression when it is nearly fully compressed and low forces and high axial compression at all other stages of compression.

Patent CA-2142424-A1 (CA)
Inventor: HEMP MELVIN R
IPC: B01D27/08
Filed: 1995-02-13
Abstract: A filter assembly is provided for a manifolded water filtration system and includes a filter element, a brine seal located at the top of the filter element and engaging a boss depending from the system manifold. The brine seal isolates a rinse water discharge port, communicating with an outlet of the filter element, from an untreated water inlet port formed in the boss so as to ensure that the water to be treated passes through the filter membrane as opposed to directly out of the rinse water discharge port. This configuration eliminates the need for an exterior feed line, thus simplifying the system and preventing vibration during system start-up.      The brine seal also structurally reinforces the filter element, facilitates assembly of the filter, increases the capacity of the assembly, and reduces the chances of failure and leakage.
Patent CA-2142943-A1 (CA)
Inventor: CHANG EDWARD
IPC: H05K3/34
Filed: 1995-02-20
Abstract: A method of depositing a solid substance on the surface of the substrate in which the solid substance is dissolved in a solvent to create a first solution. The solid substance is less finely divided prior to dissolution than when deposited on the substrate and the deposition density of the solid substance on the substrate is regulated at least in part by solid substance concentration. The solid substance is insoluble in a liquified gas and the first solution is soluble in the liquified gas. The solvent also is capable of depressing the freezing point of the liquified gas upon expansion of the liquified gas. The first solution is dissolved in the liquified gas to create a second solution having a sufficient concentration of the solvent relative to the liquified gas that solidification of the liquified gas is substantially prevented upon the expansion thereof. Preferably, this concentration of solvent is a minimum to prevent overuse of environmentally hazardous solvents. The solution is sprayed against the substrate so that a portion of the liquified gas flashes into a vapor and the second solution containing a remaining portion of the liquified gas contacts and thereby coats the surface substrate. The remaining portion of the liquified gas is evaporated along with the solvent, so that the solid substance remains as a deposit on the substrate. The method has particular application to making very fine depositions such as are required in the electronics industry to coat contacts of printed circuit boards with flux prior to soldering.
