Patent CA-2231847-C (CA)
Inventor: COLEMAN WILLIAM E JR
IPC: H01P5/18
Filed: 1996-09-13
Granted: 2001-04-03
Abstract: A stripline directional coupler (40) having a quarter-wave transmission line  (54, 62) added either between the isolation port (52) of the coupler and the  termination impedance (56) or between the input port of the coupler and the signal input (46) reduces the degradation of coupler directivity caused by impedance mismatch of the transmission lines (42, 44) with the source, load and/or termination impedances (56). With the transmission lines (42, 44) and  additional quarter-wave transmission line (54, 62) formed on the same substrate material, coupler directivity is insensitive to the value of the characteristic impedance of the transmission lines (42, 44). This allows the  use of less expensive substrate materials and manufacturing processes during  stripline directional coupler construction.

Abstract: A machine is disclosed, for making a groove into a ceiling, a wall or a floor. The machine has a powered truck-like vehicle having a support base and an apparatus mounted on the base. The apparatus has two parallel spaced-apart booms pivotally mounted on the base and a holding head slidably mounted on each boom. An elongated main rail mounted on the heads in such a way that it may rotate about a longitudinal axis parallel to itself. A saw carrier is mounted on the main rail and a motorized saw is mounted on the saw carrier. The saw carrier can move along the main rail and the saw can be displaced on the saw carrier in a direction perpendicular to the longitudinal axis. The main rail is mounted on the heads with curved support members which are each pivotally connected to the respective head for rotation about the longitudinal axis. Each curved support member has a first end on which the main rail is mounted, so as to allow the main rail to pivot about a transversal axis perpendicular to the longitudinal axis. Each curved support member has a second end linked to the respective head in such a way that the curved support member can pivot about in connection to the respective head for levering the first end of the curved support member and, therefore, for rotating the main rail about the longitudinal axis.  Each opposite end of the main rail preferably has an extendible leg for stabilizing the apparatus whenever required. This leg can be oriented in a third direction perpendicular to the longitudinal axis and perpendicular to a surface. Each leg can be attached at two different places in such a way that it extends more or less further.

Title: Polysaccharide conjugate capable of binding cellulose
Inventor: GIDLEY MICHAEL JOHN
IPC: C07K16/00
Filed: 1998-12-23
Granted: 2009-12-01
Abstract: A polysaccharide conjugate comprises a polysaccharide with an attached entit y having a molecular weight of at least 5000, the polysaccharide conjugate being capable of binding to cellulose. Preferred polysaccharides include tamarind seed xyloglucan, locust bean gum and enzyme modified guar. The attached entity is suitably a protein such as an enzyme, antibody or antibody fragment, or a particle possibly having a benefit agent such as a fragrance associated therewith. Because the polysaccharide conjugate binds to cellulose, which is present in cotton and other fabrics, paper, etc., binding of the conjugat e to cellulose brings the attached entity into close proximity to a surface of or containing cellulose. The invention thus enables targeting of attached entities to such surfaces. The invention also provides a product incorporating the polysaccharide conjugate of the invention. The product is conveniently a laundry product such as a fabric washing product, e.g., a detergent product, or a fabric conditioning product. In thi s case the attached entity may be an enzyme, a particle bearing fragrance, etc. The invention also provides a method of targeting binding of an entity to cellulose by use of the polysaccharide conjugate of the invention.
