Patent CA-2183781-C (CA)

Abstract: A plastic wall board tape (10) having a raised center section (11) and outwardly extending wing areas which have a coating of fibers (13) adhered to both sides. The raised center (11) of the tape is weakened at the top to cause the tape (10) to crease in a straight line when it is folded at an inside or outside corner to define a straight edge at the corner joint. The combination of the rigid water impervious tape (10) and the fibers (13) allows the tape (10) to be applied over imperfectly fitted wall board joints with large imperfections because the fibers (13) will achieve a mechanical bond with the wall board compound or other joint materials, allowing a slow cure, and the tape (10) will not be softened by the compound. When used on an inside comer, the tape (10) can be finished merely by striking the outer edge with compound as the top surface is a finish surface and requires paint only. The tape (10) can have triangular cutouts in the wings and removable end strips to facilitate taping of curved corner joints.

Abstract: There is provided a guided drilling system and an in-the-hole shock absorber adapted thereto. The guided drilling system includes a drill string configured to continuously and accurately bore a hole in the ground without the need to periodically break the connection of the drill string. In order to protect the components of the drilling system a hollow core shock absorber for percussive drill strings has been designed. A centrally disposed coil spring transmits the necessary thrust to a percussive hammer while providing a resilient cushion for vibration displacement Pressurized fluid flows through the center of the shock absorber through a poppet valve.

Abstract: Method and apparatus for providing a filtered signal which indicates of a flow of fluid to a fluid pressure communication conduit, the flow being dependent upon the pressure of fluid in a chamber. The pressure in the chamber is controlled by one or more pressure adjusting valves. The invention provides for receiving into a data processing module one or more valve signals indicating open states of the pressure adjusting valve or valves and also a flowrate signal from a flowrate sensor, which represents the real instantaneous flowrate, and it is this signal which needs to be filtered to remove transients.      The invention provides for choosing between a first processing mode and a second processing mode for the flowrate signal. The first processing mode is used when the second processing mode is not in effect and when neither of the valve signals indicates an open valve. The second processing mode is activated when a valve signal indicates an open valve. The second processing mode, when activated, proceeds according to a predetermined procedure and then returns to the first processing mode after no valve signal indicates an open valve.      The signal is processed by either the first processing mode or the second processing mode, depending on whether valve signals have been received, and provides the filtered signal as an output to equipment external to the data processing module.

Abstract: A method and system that uses personal information as a key when distributing information. If software is purchased, the buyer gives the seller his or her credit card number and at least three additional items of personal information, as an example, to use as a key. The personal information can include, but is not limited to, the purchaser's social security number, telephone number, expiration date of the credit card, address, mother's maiden name, children's names, bank account information, etc. This key is embedded in the purchased material. The material is then sent or downloaded to the purchaser. To activate the software, the purchaser must enter the key, which is the personal information. A comparison is then madeof the key embedded in the software and the key that was just entered. If the keys do not match, the software can not be installed and accessed. If the keys do match, the software will be installed and can be accessed. In certain instances, the key may need to be input every time the software is to be accessed.

Granted: 2011-12-06
Abstract: The present invention relates to live attenuated gram-negative vaccine carrier strains which are useful for expression and delivery of heterologous O-antigens (O-PS) from gram-negative pathogens. Said strains are deficient in the expression of homologous O-PS due to a defined genetic modification, preferably a deletion, and, thus, capable of efficiently expressing a desired heterologous O-PS in such a way that it is covalently coupled either to homologous or heterologous LPS core lipid A. The present invention furthermore relates to live vaccine carrier strains containing a heterologous gene or a set of heterologous genes encoding O-PS. Preferably, said strains additionally contain genes necessary for the synthesis of complete smooth heterologous LPS. The present invention also relates to live vaccines comprising said strains, preferably for immunization against gram-negative enteric pathogens.

Abstract: Two coating supply tubes extend parallel to one another and run the full width of a moving substrate in the cross machine direction. Coating is supplied separately to each supply tube from opposite ends. The supply tubes discharge coating through spaced metering holes into an application chamber defined between a sidewall mounted to each supply tube. The counterflow arrangement of the coating supply tubes results in the fall off of coating pressure in one tube being cancelled out by the increased pressure in the other tube. The fall off may be further counteracted by varying the spacing between metering holes the greater the distance from the coating inlet, by varying the diameter of the metering holes, or both. The tendency of the heated coating to cause a temperature gradient may be counteracted by cantilevering the applicator head on arms from a support beam through which a temperature controlling fluid is circulated.
