Patent CA-2236656-C (CA)
Title: Continuous chain caster and method
Inventor: SPEED BOBBY BRUCE
IPC: B22D11/06
Filed: 1996-11-13
Granted: 2003-08-05
Abstract: A continuous chain caster has upper and lower mold assemblies (10, 16) comprising endless belts (12, 18) and chains (14, 20) traveling at synchronized speeds. The mold assemblies meet to form a mold channel (22) which is filled with molten metal from a headbox (24) and feed tip (27). As the molten metal passes through the mold channel, the metal solidifies into the shape of the mold channel. Each belt is positioned outside the corresponding chain so that the smooth surface of the belt defines the surfa ce of the mold channel thereby preventing the formation of fins between mold blocks (32) which make up the chain, protecting the chain blocks and neutralizing deformations in the chain blocks. The upper and lower blocks of  the chains have protrusions at opposite ends which engage the opposing block s to form the sides of the mold channel. By sliding the chains relative to eac h other, the width of the mold channel is adjustable.

Title: Arc fault detector with circuit interrupter
Inventor: BRADLEY ROGER M
IPC: H02H1/04
Filed: 1998-12-16
Granted: 2007-07-10
Abstract: An arc fault circuit interrupter (AFCI) device functions to provide protection from potentially dangerous arc faults. The arc fault detector can be used stand alone or in combination with circuit interrupting devices such as IDCIs and ALCIs. The AFCI device detects both AC line frequencies and high frequencies associated with arcing. Both average and instantaneous values of both AC line frequency and high frequency arcing signals are processed to generate an arc fault signal. The trip mechanism of the device trips on the occurrence of either an arc fault or a ground fault. The device allows the arc detector to differentiate between destructive high level arcing and low level arcing such as generated by typical household appliances and equipment. This serves to decrease the occurrence of false tripping. The device also includes a timer circuit, which permits the user to temporarily disable the arc detector, and includes communication means to permit the device to communicate the occurrence and location of the arc fault to a centralized monitoring station.

Title: Radiant system in accumulators and resultant product
Inventor: DEABREU PAULO EMMANUEL
IPC: H01M50/50
Filed: 1998-05-20
Granted: 2005-11-01
Abstract: Patent of Invention "RADIANT SYSTEM IN ACCUMULATORS AND RESULTANT PRODUCT", objectifying the optimization of energy's generation, storage and use, allowing the reduction of costs through ultra-fast recharges, using pulsating processes that cause high-frequency radiations, through tensions higher than the ones currently used, without losses in the characteristics of electricity's conventional use, allowing greater facilities for its use.   The present Patent of Invention allows the ultra-fast recharge of accumulators and or capacitors, adding several pairs of conducting branch lines with adequate insulation, to proceed the recharging of the accumulators and or capacitors by means of radiant effect through the lower part of the plates, by the pulsating tension that causes a high-frequency radiation, feeding the plates preferentially in the sequence from the plates in the extremities to the ones in the centers, acting simultaneously on all the cells, totally independent from the conventional system, which is preserved for the discharge of the accumulators and or capacitors through the upper part of the plates, using the terminals that are currently used.
Patent CA-2263170-C (CA)
Title: Persistent heap for dynamic picture objects
Inventor: MOORE DONALD W
IPC: G05B19/418
Filed: 1997-08-28
Granted: 2008-12-30
Abstract: There is provided a process control system having a display program that permits a program designer to create and edit dynamic picture objects in a persistent heap and save the heap to a storage medium. The display program rapidly reads the dynamic picture objects from the storage medium and invokes the objects for viewing on the system's interactive display. When the persistent heap is subsequently read from the storage medium by an operator, the dynamic picture objects stored in the heap do not need to be instantiated and, thus, invocation of the objects is accelerated and optimized. Accordingly, the persistent heap greatly improves the speed in which picture objects can be read from the storage medium, processed by the display program and called-up to the interactive display.

Title: Hypersensitive response induced resistance in plants by seed treatment
Inventor: QIU DEWEN
IPC: A01N63/50
Filed: 1997-12-04
Granted: 2006-10-10
Abstract: The present invention relates to a method of imparting pathogen resistance to plants.

Abstract: In a method of manufacturing multiple kinds of products (W) in an arbitrarily selected order in one manufacturing apparatus, the rate of operation of the welding robots to be disposed in each of assembly lines (1, 2, 3) for each of parts (W1, W2, W3) is improved, the cost for equipment investment is reduced, and the time required to introduce a new kind of motor vehicle into the manufacturing apparatus is shortened, whereby the productivity is improved. The manufacturing apparatus is made up of: a plurality of part assembly lines (1, 2, 3) for assembling a plurality of parts (W1, W2, W3); a combining station (4) for tack-welding these parts to thereby assemble a product (W); and a reinforce-welding line for reinforce-welding the product (W). The number of welding points for welding each of the parts (W1, W2, W3) in the respective assembly lines (1, 2, 3) is made equal to one another for all kinds of vehicles. Those welding points of each of the parts (W1, W2, W3) which fall short of a required number of welding points are welded in the reinforce-welding line (5).
