Abstract: A glass heating system (26) includes a low emissivity sheet (14) of coated glass and a capacitor (C1 or C2) for capacitive coupling the coated glass sheet (14) to a power source (16). The low emissivity glass sheet (14) is economical to produce and to provide superior thermal properties. The low emissivity glass sheet (14) has a low sheet resistance and is coupled to one or more capacitors (C1, C2) to increase the impedance and to reduce the power dissipation by the coated glass sheet (14). The exact amount of power to be delivered to the coated glass sheet (14) can be varied by changing the capacitor (C1 or C2). The low emissivity glass sheet (14) has improved thermal characteristics for use in insulating glass doors for freezers and refrigerators. In a two-paned insulating glass door, the capacitor (C1 or C2) can be conveniently mounted in the frame of the door or in the space between the two panes.

Title: An apparatus and method for processing, creating, and dispensing a roughage ration for livestock
Inventor: PATTERSON R C
IPC: A01K5/00
Filed: 1999-09-30
Abstract: A machine adapted to be towed by a tractor and powered by the PTO and hydraulic power system of the tractor for transporting, processing and blending two different types of roughage of substantial size and weight into a desired ration for a more efficient and economical nutritional balance and better palatability as well as dispensing the ration to livestock. This improved machine is characterized by two independently hydraulically driven floor chains that are each capable of carrying a large bale (or bales) of roughage through a series of vertically aligned shredders at different rates of speed. This produces a blend of differing types of roughage consistent with the desired nutritional component considered most economical and efficient for the particular livestock being fed. The processed ration is dropped onto a conveyor chain and immediately delivered into feed bunks for livestock consumption. The shredders and conveyor chain are mechanically driven. The variable speed of one hydraulically driven floor chain is controlled by a flow control divertor, while the speed of the other hydraulically driven floor chain remains constant.

Patent CA-2297902-A1 (CA)
Inventor: DENT PAUL WILKINSON
IPC: H04J13/00
Filed: 1998-07-15
Abstract: L'invention concerne un système et un procédé de communication par codage à bloc orthogonal. Des signaux codés sont transmis par répétition des transmissions de blocs de symboles accompagnés d'une variation de phase ou de signe choisis pour chaque bloc à partir d'une séquence de variations de phase ou de signe. Différents symboles sont transmis au moyen de séquences orthogonales. Le décodage met en oeuvre différentes séquences orthogonales pour séparer les signaux codés reçus en canaux séparés correspondants. Le codage orthogonal est supprimé des signaux codés transmis, et des signaux correspondants des symboles répétés sont ajoutés dans des blocs répétés reçus successivement après la suppression du codage orthogonal. Un émetteur utilise un codeur source numérique pour coder des informations en symboles et chaque symbole est répété un certain nombre de fois prédéterminées pour produire successivement des groupes de bits répétés. Chaque bit de répétition est modifié en phase ou en signe par application d'une variation de phase ou de signe déterminée par un code orthogonal attribué choisi associé à l'émetteur. Les bits modifiés en signe sont entrelacés à partir d'un certain nombre desdits groupes pour générer successivement un certain nombre de blocs composés chacun des différents bits modifiés en signe ou en phase du nombre prédéterminé de groupes répétés et comportant une variation de signe ou de phase collective correspondant à une variation de signe ou de phase commune partagée par tous les bits du bloc. Les blocs entrelacés modulent ensuite un signal radio pour effectuer la transmission.

Abstract: The invention especially relates to components used as ceramic catalysts in denitration plants. In said plants, the catalysts are impinged upon by low frequency sound. This enables the surfaces of the catalysts to be cleaned and simultaneously enhances their efficacy. If the catalysts cannot be reactivated they are subjected to final intensive cleaning wherein they are exposed once more to low frequency sound. Subsequently, the catalysts are crushed and the ceramic material can be used in all cases where the chemical properties of the material is of no particular significance. The cleaned particles containing pollutants are dumped or disposed of in melting chamber furnaces.
Patent CA-2300083-A1 (CA)
Title: Propylene oxide purification
Inventor: RUETER MICHAEL A
IPC: C07D301/32
Filed: 1998-07-27
Abstract: Propylene oxide obtained by an epoxidation process which uses methanol as a solvent may be effectively treated to remove acetaldehyde by subjecting the crude epoxidation reaction product to fractional distillation. The methanol solvent is utilized during such distillation to lower the relative volatility of the acetaldehyde impurity, thereby making it possible to obtain a bottoms fraction containing substantially all the acetaldehyde. Purified propylene oxide having a reduced acetaldehyde concentration is removed as an overhead stream.  Water may also be effectively separated from the propylene oxide using this procedure.
