Abstract: A robotized laparoscopic system capable of executing commands of an operating surgeon is provided. The laparoscopic system includes a cylindrical tube inserted into the opening. A small-sized camera is attached to one end of the tube to capture the images of the surgical site. A bending portion is adapted to bend the tip of the tube in any direction. A driving unit controls a bending direction and a bending angle of the bending portion. A movement device moves the tube forward or backward in a longitudinal direction. A control unit independently controls the driving unit and the movement device. An input unit receives commands from the surgeon. A conversion unit converts the command input from the surgeon into digital signals and transmits the digital signals to the control unit. A support unit supports weight of the movement device by being connected to an operating or the floor.

Abstract: The invention relates to a method of removing phosphorous from sialyloligosaccharides isolated from a dairy stream using phytase.

Abstract: A heat transfer system is described for controlling the transfer of heat from a roof space into a living space of a building. The heat transfer unit (10) includes a flexible duct (14) and a ceiling vent (16) for transferring warm air from within the roof space (12) into a living space (18) below. An electric fan (20) located at the top end of the flexible duct (14) is arranged to draw warm air from the roof space (12) down through the duct (14) into the living space (18). A first temperature sensor (22) mounted adjacent the top end of the flexible duct (14) senses the temperature of the air within the roof space (12). A second temperature sensor (24) located in the room below senses the temperature of the air within the living space (18). An electronic controller (26) controls the operation of the electric fan (22) in response to temperature sensing signals from the first and second temperature sensors (22, 24) respectively.

Abstract: The lid with re-closable spout invention can be used with a hot and/or cold beverage container or other fluid container. The lid fits onto the container as is known in the art. The lid includes a spout formed on the lid and extending from the lid which allows one to access the contents of the fluid container. The spout can be positioned in a closed position wherein it is folded in to prevent the contents of the fluid container from exiting the spout. The spout may be locked into a closed position. In a second, open position, the spout is folded out to allow the fluid within the fluid container to be poured out of the fluid container through the spout. After use and/or between uses, the spout can be re-closed and re-sealed. The spout can be any desired configuration including generally square or rectangular, or generally cylindrical. The sealing means can be a zipper-type engagement formed on the upper edge of the spout.
