Patent CA-2176966-A1 (CA)
Title: Improved molten metal decomposition apparatus and process
Inventor: MALONE DONALD P
IPC: C10J3/57
Filed: 1994-11-16
Abstract: In an improved molten metal hydrogen generation bath, baffles form a draft tube or chimney-effect near the center of the bath. Flow through the chimney is aided by maintaining a temperature differential favoring convection and, optionally, a differential pressure between the portions of the bath on either side of the baffle-chimney arrangement. Feed is added to the feed zone and oxygen is added to the oxidation zone, emitting H2 from the feed zone and CO  from the oxidation zone. Baffles may be made simply of brick work or high temperature metal and can fit into existing refractory-lined molten metal vessels. Products can be mixed as syngas feed for Fischer-Tropsch synthesis.  Additionally, the Boudouard endothermic reaction (CO2 + C  2CO) can be used to control temperatures by injecting CO in place of oxygen.

Abstract: The invention is a lawn mowing blade known as a mulcher to be used on a motorized push-type lawn mower. This blade chops the grass into very small pieces which will be left on the lawn to break down and enrich the soil. This eliminates the need for raking, and in addition improves the quality of the lawn. The invention will cut the grass evenly in damp conditions as well as when it is dry. It also mulches and bags grass and leaves which is great for gardens, shrubs etc. This invention is intended to improve your present machine, but it is necessary to purchase the proper mulching baffles to fit your model of mower.

Patent CA-2191198-A1 (CA)
Title: Method and apparatus for producing high purity and unagglomerated submicron particles
Inventor: AXLEBAUM RICHARD L
IPC: C23C16/56
Filed: 1995-05-23
Abstract: A method and apparatus for reacting sodium vapor with gaseous chlorides in a flame to produce nanoscale particles of un-oxidized metals, composites and ceramics. The flame is operated under conditions which lead to condensation of a NaCl by-product onto the particles. The condensate encapsulates the particles and aids in controlling desired particle size and preventing undesirable agglomeration among the particles during synthesis. Following synthesis, oxidation of the particles is inhibited by the encapsulation, and handling character of the products is greatly enhanced. Electron microscopy has revealed that synthesized products are composed of discrete nanoparticles in a NaCl matrix. The NaCl encapsulate has been effectively removed from the particles by both washing and known sublimation technique at 800 °C under low pressure.

Abstract: A high strength, porous PTFE sheet material having high strength in all directions within the plane of the sheet material. The sheet material has, within the plane of the sheet, a higher minimum tensile strength, matrix tensile strength, secant modulus and matrix secant modulus than previously known porous PTFE sheet materials. The sheet material is a laminate of multiple layers of porous PTFE film, preferably uniaxially expanded film, wherein the orientation of the direction of the fibrils of any layer varies slightly, such as about ten degrees, from the orientation of the fibrils of the adjacent layer. The sheet material is particularly useful as a surgical repair patch and especially as a blood vessel repair patch because of its high strength, flexibility, biocompatibility and very low rate of suture line bleeding.

Title: Virtual Authentication Network for Secure Processors
Inventor: SPRUNK ERIC
IPC: G06F21/00
Filed: 1997-01-07
Abstract: The integrity of a group of secure processing elements (10, 20, 30, 40, 50, 60, 70, 80) in a communication system is ensured with a validation scheme.  Member elements (10, 20, 30, 40, 50, 60, 70, 80) are checked by adjacent members to determine whether a member has been tampered with or operatively removed from a group.  If a member is found to be untrustworthy, propagation of group characteristic information to that member will be halted.  The group characteristic information defines the group, and is required by each group member in order to function.  The untrustworthy member is therefore effectively exiled from the group.  An efficient network topology minimizes inter-member message traffic while maintaining group robustness.
Patent CA-2194546-A1 (CA)
Title: A method and means for frequency hopping in a radio communication system
Inventor: ANDERSSON CLAES H KAN
IPC: H04B1/713
Filed: 1995-07-13
Abstract: Frequency hopping and hops between time-divided channels (K1, K2, ..) is carried out in a mobile telecommunications system. Hop sequences are established for individual connections for hops between the channels, thereby improving utilization of the channels in the system. Interference (I) is measured on the channels (K1, K2, ..) for individual connections between a base station (BS1) and a plurality of mobile stations. The connections are bidirectional, having an uplink and a downlink. The measured interference values of the uplink and the downlink respectively are stored in an interference list (IL) for each of the connections. The drawing shows three interference lists (IL1up-IL3up) in the uplink, including channel numbers (K1, K2, ..) and the measured interference values (I1, I2, ..). The interference values are converted to weight values (0.1; 0.3; ..) in a conversion circuit (I/Wup), and the weight values are then stored in weight lists (WL1up-WL3up).  The weight values are analyzed in an allocation circuit (W/Hup), which allocates channels to individual hop sequence lists (HL1up-HL3up). Each connection is allocated a respective hop sequence list. The hop sequence lists are sent to respective mobile stations, thereby providing the mobile stations with information as to which hop sequence list shall be used.

Abstract: Briquette comprising silicon-containing residues as an additive for metallurgic purposes.          Silicon-containing residues, as they accumulate especially during the synthesis of organosilanes out of metallic silicon, and especially methyl chloride, are processed according to the invention to briquettes, being additives for the quality adjustment of cast iron being produced in a cupola furnace in order to avoid either costly regeneration for the recovering of the valuable components or the total dumping of said silicon-containing residues. Besides the silicon-containing residue the briquettes contain 1 - 10 percent by weight of cardboard fibre, 5 - 40 percent by weight of hydraulic cement and 0 - 20 percent by weight of additional additives having influence on the quality of the cast iron. The cement- and cardboard fibre-containing briquettes are mechanically and thermally sufficiently stable with respect to the operation of the melting furnace. The yielding rate of the inserted small-sized silicon in the cast iron is about 85 % and reaches thereby the same range of lumpy ferrosilicon.
