Title: Loop-type thermosiphon and stirling refrigerator
Inventor: CHEN WEI
IPC: F28D15/02
Filed: 2003-04-07
Abstract: A loop-type thermosiphon that is operable stably independently of fluctuatio n in thermal load, and a Stirling refrigerator using the loop-type thermosipho n. A loop-type thermosiphon where heat is carried by a working fluid from a hig h temperature heat source (5) has a heat absorption unit (1a), an evaporator ( 1) that takes away heat from the high temperature heat source through the heat absorption unit and evaporates the working fluid, a condenser (3) located at a higher place than the high temperature heat source and condenses the working fluid evaporated in the evaporator, and pipes (2, 4) inter connecting the evaporator and the condenser so as to form a loop. The working fluid (22) passed through the condenser (3) is brought into contact with the heat absorption unit (1a) before the fluid is stayed in a liquid container (21) f or the working fluid so that heat exchange is carried out.
Patent CA-2482700-A1 (CA)
Inventor: NAIPAWER MICHAEL P III
IPC: E04D1/22
Filed: 2003-03-31
Abstract: Laminated hip and ridge asphalt shingle (10) having a first, a second and a third layer (21), (50) and (20) laminated together by a lamination adhesive (42). The first layer (21) is of two L-shaped configurations, each having a horizontal head portion (30) and a vertical butt portion (25). The horizontal head portions are superimposed on each other, while the vertical butt portions are placed adjacent to each other and form a gap (22) which allows bending of the first layer (21) thereby preventing stress and breaking. The second layer (50) overlaps the first layer (21). The third layer (20) only overlaps the head portion of the head portion of the second layer (50). The top surface of the shingle is coated with mineral granules, while portions of the undersurface of the shingle are coated with a self-seal adhesive to secure the shingle to the hip or ridge of a roof. Disclosed also is a process for installing the hip and ridge shingle units which includes: bending a first unit along a central flood line, pressing and adhering it to both sides of the intersecting plane of a roof; nailing the unit to the roof deck on both sides of the hip or ridge; bending a second unit (50) along a central fold line, pressing and adhering it to both sides of the intersecting plane and to the first unit (21) so that the butt portion of the second unit (50) overlaps the head portion of the first unit (21); nailing the second unit (50) to the roof deck on both sides of the hip or ridge; and similarly securing the necessary additional units to the intersecting planes of the roof to complete the installation.

IPC: B65H29/12
Filed: 2003-07-07
Abstract: In order to process flat objects (10), especially for packing printed produc ts or small groups of printed products using an almost continuous packing material, the objects are guided over part of the periphery of a processing drum (1) in a transport flow in which they are successively arranged essentially parallel to the transport direction and optionally between two layers of packaging material. Said processing drum (1) comprises regularly alternating, axially extending support elements (2) and processing elements (3) on the periphery thereof, the radial position of said elements being adjustable, for example, for adaptation to different formats of the objects to be processed. The processing drum also comprises a pressing strip (4) which extends from an input point (A) to an output point (B) along the periphery o f the drum and by which means the objects guided around the periphery of the drum are held and pressed against the tool elements. So that a change of the radial position of the support elements and the tool elements necessitates n o other adjustments, the pressing strip (4) is arranged in such a way that it guides the objects towards the periphery of the processing drum and/or away from the same.

Patent CA-2504934-A1 (CA)
Inventor: VENTURA RODRIGO ULEP
IPC: C22B11/08
Filed: 2003-10-22
Abstract: Precious metals such as gold can be extracted from a refractory ore using a conventional cyanide leaching step and with reduced cyanide consumption by p re- treating the ore prior to cyanide leaching. The refractory ore is pretreated by fine grinding and an initial leaching step which uses inexpensive limesto ne and lime to maintain the initial leach relatively alkaline. Oxygen is added to the initial leaching step and the conditions are carefully controlled to onl y partially oxidize the ground ore to between 9-15 %. The initial leaching ste p can be carried out at temperatures of less than 100 degrees C and at atmospheric pressures. The pre-treated ore is then leached by a conventional cyanide leaching step to recover the precious metal and cyanide consumption can be reduced by more than two thirds.

Abstract: A combination cultivator and hoe having cultivator tynes of uneven length parallel to one another and inclined with respect to the handle. A hoe blade preferably with a sharpened forward edge is connected on one or both ends of the row of cultivator tynes extending substantially parallel to the type and to the handle. The uneven lengths of the cultivator tynes reduce the initial force needed to be applied to penetrate the soil and the blade or blade exert substantially no drag when the tynes are moved forwardly or backwardly through the soil. The hoe blade or blades can be used with the tool rotated 90* from the cultivating position. The blade is pushed against the stem of the weeds or other growth to be removed, slightly below the soil surface.

Title: Framework to enable integration of anti-spam technologies
Inventor: MCMILLAN BRUCE A
IPC: G06F19/00
Filed: 2004-07-26
Abstract: A method that enables multiple spam detection solutions to be deployed in a manageable and rational manner to determine if a message is spam is presented. A framework invokes anti-spam filters to analyze the message and return confidence levels of whether a message is spam. The framework evaluates the highest confidence level against a set of defined thresholds. If the highest confidence level is greater than the highest threshold set by the administrator, the action specified for the highest threshold is taken. The highest confidence level is also compared against all thresholds and the action associated with the nearest threshold that has been exceeded is taken.

Title: Delivery systems for functional ingredients
Inventor: FARBER JONATHAN
IPC: A23L1/30
Filed: 2003-03-25
Abstract: The present invention provides oral delivery systems for functional ingredients, such as drugs, nutritional supplements, botanicals, and vitamins.  The delivery systems comprise an ingestible matrix within which the functional ingredient(s) are substantially uniformly and completely dispersed and in which degradation of the functional ingredient(s) is minimised. The matrix comprises 1) one or more carbohydrate; 2) one or more sugar, sugar syrup and/or sugar alcohol; 3) one or more hydrocolloid; 4) one or more polyhydric alcohol; 5) one or more source of mono- or divalent cations, and 5) water. The combination of carbohydrate and hydrocolloid in the matrix ensures that the delivery system readily retains the solvent component and thereby prevents separation of the solvent from other components of the matrix. The invention also provides methods of preparing and using the delivery systems.
