Patent number: 9316522Abstract: A fluid level gauge includes a housing having a first end and a second end, and a window disposed in the housing, proximate to the first end. The fluid level gauge further includes an optical sensor disposed in the housing, proximate to the second end. A prism is disposed in the housing, between the optical sensor and the window, such that the prism and the window define a fluid chamber therebetween. The housing further includes a plurality of through holes that provides a fluid path from outside the housing to the fluid chamber.Type: GrantFiled: August 8, 2012Date of Patent: April 19, 2016Assignee: Eaton CorporationInventors: Gregory Kopansky, Rolland James, George Birch

Patent number: 8124373Abstract: The invention is directed to novel enzymes that convert sucrose to isomaltulose. More particularly, the present invention discloses novel sucrose isomerases, polynucleotides encoding these sucrose isomerases, methods for isolating such polynucleotides and nucleic acid constructs that express these polynucleotides. Also disclosed are cells, including transformed bacterial or plant cells, and differentiated plants comprising cells, which contain these sucrose isomerase-encoding polynucleotides, as well as extracts thereof. Methods of producing isomaltulose are also disclosed which use the polypeptides, polynucleotides, cells, cell extracts and plants of the invention.Type: GrantFiled: February 8, 2011Date of Patent: February 28, 2012Assignee: The University of QueenslandInventors: Robert George Birch, Luguang Wu

Patent number: 8022269Abstract: The present invention relates to methods for increasing the yield of a compound produced by an organism. More particularly, the present invention relates to methods for increasing the total or soluble carbohydrate content or sweetness or increasing the content of an endogenous carbohydrate of a plant tissue by producing a sugar-metabolizing enzyme that catalyzes the conversion of an endogenous sugar (one that is normally produced in the plant) to an alien sugar (one that is not normally produced in the plant at the same developmental stage). The invention also relates to plants and plant parts that produce a sugar-metabolizing enzyme to yield an alien sugar, with the consequence of higher total fermentable carbohydrate content, and to fermentable carbohydrates and other products derived therefrom.Type: GrantFiled: October 11, 2006Date of Patent: September 20, 2011Assignee: The University of QueenslandInventors: Robert George Birch, Luguang Wu

Patent number: 5863268Abstract: An ice hockey stick comprising a blade and an elongate, narrow handle connected to a top end of the blade. The handle and blade are formed from a strong, lightweight metal such as aluminum alloy. The blade has a number of relatively small holes extending through it for purposes of weight reduction. These holes are distributed over the surface of the blade. Preferably the handle is detachably connected to the blade. A preferred embodiment is for a goalkeeper and, in this version, the blade has an ice engaging portion and an upstanding portion which extends at an obtuse angle to the ice engaging portion. The holes are distributed over both portions of the blade.Type: GrantFiled: January 5, 1996Date of Patent: January 26, 1999Inventor: Thomas George Birch

Patent number: 5785100Abstract: A liquid retention system is disclosed which includes a tank for receiving and retaining a liquid, and including a filling port. A dispenser supplies liquid to the tank through a nozzle which engages the filling port. A pneumatic detection system is provided for fluidly measuring the liquid level state within the tank; i.e., determining whether or not the tank is full. An optical detection system is also provided, which cooperates with the pneumatic detection system, for optically measuring the liquid level state within the tank.Type: GrantFiled: February 14, 1997Date of Patent: July 28, 1998Assignee: Vickers, IncorporatedInventors: Steve Showalter, George Birch
