Title: Energy efficient system and method for reducing water friction on the hull of a marine vessel
Inventor: WIPPER DANIEL J
IPC: B63B1/38
Filed: 1998-12-02
Abstract: An energy efficient system for reducing the water friction on the hull of a marine vessel (10). The contact of water with the portion of the outer surface of the hull of a marine vessel (10) which normally engages the water is reduced by the strategic induction of pressurized or compressed air or gas to cover that outer surface. The compressed air is retained on the outer surface by various grooves (30), channels (66) or semi-flat surfaces (124) running the length of the vessel's bottom and in certain applications vertical sides, which prevent the flow of the compressed gas to the surface of the water. The pressurized air or gas is recaptured before exiting the stern or sides and recycled to the bow through the means of an energy efficient circulation system (34, 36, 37, 38), thus recovering the energy in the compressed air or gas which has flowed from bow to stern. The larger and the deeper the hull displacement, the greater is the efficiency realized by the recycling of the compressed air or other gas.

IPC: G06F13/00
Filed: 1998-12-23
Abstract: A means of providing session control over a network such as the Internet is disclosed. Traditionally, the Internet protocols define a session between a client and a server as one page request and one page response. This does not permit the servers to ascertain how long a client is accessing a page or whether a page containing database information is being viewed by two clients simultaneously.  In accordance with the present invention, a page contains a script that causes the page to send beat signals from the client to the server at particular times to indicate to the server that the client is continuing to view the page. When the client releases the page, the beat will stop and the server will know that the client has released the page.

Patent CA-2325774-A1 (CA)
Inventor: LAROCHE ANDRE J
IPC: A01H5/00
Filed: 2000-12-08
Abstract: The invention provides the nucleotide sequence of a novel .beta.-(1,3) exoglucanase gene denoted as cbeg1 of the soil-borne fungus Coniothyrium minitans. The deduced amino acid sequence of the encoded .beta.-(1,3) exoglucanase enzyme, denoted Cbeg1, is also provided.  Encoded .beta.-(1,3) exoglucanase Cbeg1 is specific for the substrate laminarin, in that results showed no activity with other substrates tested, such as carboxymethylcellulose, barley .beta.-glucan, lichenan, oat spelt xylan and birchwood xylan. The pH and temperature optima for .beta.-(1,3) exoglucanase Cbeg1 are 6.0 and 57°C, respectively. Cbeg1 contains 784 amino acids, and has a predicted isoelectric point (pI) of 6.0 and molecular weight of 83,646 Daltons. The invention further provides vectors and cells comprising a nucleic acid molecule encoding the cbeg1 gene, and methods for producing .beta.-(1,3) exoglucanase Cbeg1. The cbeg1 gene is compatible with a eukaryotic heterologous expression system, making it particularly useful for a wide range of industrial applications, such as improvement of plant resistance to fungal phytopathogens or use in ruminant microbial transgenic strategies to improve feed digestion and nutritive carbohydrate availability from forage feed. In addition, the high activity of Cbeg1 over broad pH and temperature ranges may be beneficial for use in high temperature industrial applications, such as bleaching of pulp, which require temperatures greater than 37°C.  Further, Cbeg1 may complement degradation initiated by endoglucanases which release oligoglucans, in that .beta.-(1,3) exoglucanase sequentially hydrolyzes .beta.-(1,3) glucan fragments and is required to hydrolyze oligoglucan fragments completely to obtain D-glucose, which can be assimilated.

Title: Method and apparatus for limiting torque in a feeder
Inventor: PRITCHETT WAYNE W
IPC: B65H3/06
Filed: 2000-11-10
Abstract: A method and device for reducing the maximum torque to rollers mounted on a drive shaft of a drive roller assembly. By using a plurality of slip clutches, each for engaging an individual roller to the drive shaft and setting a maximum torque for the individual rollers, each roller is coupled to the drive shaft when the tangential force exerted on the roller does not exceed the maximum torque, and each roller is mechanically decoupled from the drive shaft when the tangential force exerted on the roller exceeds the maximum torque. Because each roller has a separate slip clutch, each roller can be mechanically decoupled from the drive shaft without affecting the other rollers coupled to the drive shaft.

Abstract: The object of this invention is to provide a sheet guide unit for a sheet-fed press which will prevent the sheet from flapping or fluttering, and allow sheets of thinner paper to be conveyed smoothly even when a skeleton cylinder, which is better suited to thicker papers, for preventing the air streams exiting from both ends of the sheet guide surface from colliding with the frame and causing turbulence. The sheet guide unit according to this invention is provided under an intermediate cylinder or a delivery cylinder, and separated from the cylinders by a small sheet guide space for guiding the sheet. It has a curved sheet guide surface with which the lower surface of the cylinder creates the small sheet guide space, the space through which the air stream is directed; an air supply chamber which is behind the sheet guide surface; a plurality of air vents which vent air from the air supply chambers into the small sheet guide space, the air vents facing away from each other toward the sides of the cylinder on either side of its center line which vent air along the surface of the curved sheet guide surface along the width of the cylinder, so that the difference in the velocity of the air flow above and below the sheet being conveyed causes the sheet to be drawn toward the curved sheet guide surface and suspended slightly above the curved sheet guide surface as the sheet is conveyed; a pair of air aspiration chambers provided adjacent to the air supply chamber on the outer sides of the cylinder into which the air is aspirated; and an air guide fin which is an outer extended portion of the curved sheet guide surface into the air aspiration chamber, and serves for directing the air into the air aspiration chamber. The volume of air drawn out from the air aspiration chambers on either side of the cylinder is larger than the volume of air aspirated into the air aspiration chambers, so that a negative pressure in the vicinity of the both ends of the sheet guide surface is created.

The MASER (50) output is transmitted within the existing magnetic flux envelope created by the magnetic field and the power line (26) acts as a magnetic waveguide for the coherent magnetic frame emission from the MASER (50). Inductive coupling is used to receive the transmitted information.
