Patent CA-2134462-A1 (CA)
Inventor: KELLY PETER Y
IPC: C08F255/00
Filed: 1994-04-22
Abstract: A method for the grafting of a monomer onto a polyolefin in the presence of an organic peroxide is disclosed. The polyolefin is a polyolefin that, when molten, undergoes cross-linking in the presence of the organic peroxide. The method comprises: (a) admixing the polyolefin in an extruder with 25 to 6000 ppm, based on the weight of the polyolefin, of an organic peroxide coated onto a carrier polymer and up to 5%, by weight of the polyolefin, of a grafting monomer capable of being grafted onto the polyolefin in the presence of the organic peroxide. The admixture is heated to a temperature above the melting point of both the polyolefin and the carrier polymer under admixing conditions to effect grafting of said grafting monomer onto the polyolefin, said carrier polymer undergoing chain scission in preference to cross-linking in the presence of the organic peroxide at said temperature.      Grafted polyolefin is extruded from the extruder. The method may be used to produce grafted polyolefins with lower levels of gels and specks, especially for use in films and adhesives.

Title: High impedance fault detector
Inventor: AL-DABBAGH MAJID
IPC: H02H1/00
Filed: 1993-07-09
Abstract: A method and apparatus for detecting high impedance faults and other arcing phenomena in an electrical distribution sys-tem. Electrical signals on the distribution system are monitored and a number of frequency components isolated, such as zero-se-quence current and voltage, second harmonic voltage, third harmonic current, eighth harmonic voltage and current, and a mea-sure of magnitude of the components are taken over successive data acquisition periods. The measures of the component magnitudes are formed into a pattern for each data acquisition period, and the difference between patterns for successive periods are compared against a pattern threshold which is set to suit the characteristics of the distribution system. A pattern difference greater than the pattern threshold indicates the possibility of an arcing fault, which can then be confirmed by determining wheth-er the frequency components are modulated at twice the fundamental frequency of the distribution system.

Title: Gasifier for Biomass Waste and Related Volatile Solids
Inventor: BROOKES DAVID
IPC: F23G5/027
Filed: 1996-02-29
Abstract: A gasifier is disclosed. The gasifier comprises a primary chamber for receiving therein biomass waste material and other related volatile solids to begasified. A fume transfer vent permits the escape of fumes from the primary chamber. A mixing chamber accepts the fumes from the fume transfer vent. The fumes then flow to an afterburner chamber where a burner member produces a heating flame so as to cause the additional full oxidization of the constituents of the fumes so as to oxidize the constituents. A partitioning wallis disposed between the flame chamber and the primary chamber so as to preclude the heating flame from entering the primary chamber and to also preclude the radiation from the heating flame from directly entering the primarychamber, thereby precluding direct contact and physical disturbance of the wastematerial. A heat transfer chamber in fluid communication with the afterburner chamber accepts the fully oxidized fumes therefrom. The heat from the full oxidation of the fumes causes heating of the heat transfer chamber. The primary chamber has a heat conductive floor and is superimposed on the heat transfer chamber with the heat conductive floor being disposed in separating relation therebetween so as to permit conductive and convective heating of the primary chamber, thus causing heating of the waste in the primary chamber. An exhaust vent in fluid communication with the heat transfer chamber permits venting the fumes to the ambient surroundings.
