Patent CA-2283594-A1 (CA)
Title: On contact herbicide applicator
Inventor: NYLEN TERRANCE DALE
IPC: B05C17/00
Filed: 1999-09-09
Abstract: Prior on contact herbicide applicators were generally too large to selectively apply herbicide to weeds without also getting herbicide on closely adjacent desired vegetation, they also generally did not allow the User to see where herbicide had been applied. In the instant invention a herbicide container suitable for single hand operation is filled with a combination of liquid herbicide and a weed colouring element. The top end of the herbicide container has a herbicide release head that prevents the liquid herbicide and colouring element mixture from being released until suitable pressure is applied to it. The herbicide container is relatively small, therefore the User is able to rub the herbicide release head on weeds while avoiding desired vegetation. The colouring element allows the User to see where herbicide was applied.

Inventor: BRODBECK KENNETH N
IPC: B60B15/02
Filed: 1999-10-28
Abstract: A multi-disc wheel for a tractor having an axle and a hub mounted on the axle includes a rim having an inner surface. A stub disc having a centrally-disposed access opening is connected to the inner surface of the rim. An anchor disc is also connected to the inner surface of the rim in a spaced apart disposition from the stub disc. The anchor disc and the stub disc are each configured to be connected to an appropriate hub that is, in turn, connected to the axle of the tractor. The connection between the stub disc and the axle hub is achieved by a removable attachment disc that is bolted to both the hub and the stub disc. A provision of the pair of discs between the rim and the axle allows the forces experienced by the tire to be transferred to the axle through both discs thereby spreading the force over two discs instead of the single disc of the prior art.

Inventor: DEFRANCE ROBERT
IPC: H01R4/42
Filed: 2000-03-07
Abstract: The electrical connector includes a male element traveling within a female element, the male element having a cantilevered C-clamp arm opposing a C-clamp element formed on the female element.      A spacer includes a planar surface with a passageway through which at least a portion of the male and female elements pass thereby slidably interlocking the male and female element to each other.      The spacer further includes a wire spacer which travels between the clamp arms and separates the conductors to be clamped therewithin.      Ledges are formed on the male and female elements to limit travel of the male element with respect to the female element and to limit travel of the spacer with respect to the male element. A bolt passing through the female element and threadably engaging the male element secures the male element to the female element so that the clamp arms clamp conductors as separated by the wire spacer therebetween.

Patent CA-2311490-A1 (CA)
Inventor: HOWE JOANNE
IPC: C07C59/74
Filed: 1998-11-26
Abstract: L'invention concerne une technique permettant d'éliminer l'épimérisation de l'acide aminé terminal C.alpha. dans une séquence peptidique protégée, durant le couplage, en utilisant la fraction de protection représentée en (1), que l'on appelle "lieur précurseur". Cette fraction a un certain nombre de caractéristiques. Ainsi, le groupe fonctionnel R et la fonction 2-hydroxyle sont en position para l'un vis-à-vis de l'autre, et le résidu éther est en position para vis-à-vis du résidu aldéhyde. R1 est un groupe alkyle donneur d'électrons. Le groupe R est une fraction capable de passer facilement d'un rôle de retrait d'électrons à un rôle donneur d'électrons et vice versa. Cela repose sur la notion de mécanisme de sécurité. Le principe selon lequel une liaison stable passe aisément à l'état de liaison instable en un point approprié durant une synthèse a été appliqué à la chimie des peptides pour l'élaboration de lieurs et de groupes de protection. Une approche a consisté à exploiter la facilité de conversion réductrice d'un sulfoxyde en sulfure. Lorsqu'elle est appliquée au lieur précurseur (1), cette approche permet d'obtenir des fractions de protection fonctionnelles appelées "composés lieurs".

Abstract: A counter-top paper towel holder having a base, a mounting rod extending upward from the base, and a stabilizing extension extending upward from the base at a position radially spaced from the mounting rod.   The stabilizing extension includes a handle portion and a presser arm spaced radially outward from the handle potion. The presser arm is resilient, and includes a free end for abutting the roll of paper towels mounted on the mounting rod. Grasping the handle with one hand provides support for the paper towel holder against gross movement as the free towels are pulled from the roll using the other hand. The thumb of the grasping hand may press against the presser arm to force the free end against the roll. The free end thus prevent further rotation of the roll, and assists in breaking the lines of perforation to dispense the towels.

Abstract: The present invention is a network operation center which centrally connects a plurality of external computer systems belonging to automobile dealers, manufacturers and vendors of goods and services. The network operation center provides centralized network security, allowing the dealers, manufacturers and vendors to access certain portions of each other's data while protecting other data. It further provides data translation so that incompatible data formats and structures may be shared.  Dealers with a multi-store network communicate through the network operation center with multiple manufacturers and vendors with a single network connection, reducing the need for multiple individual connections to each manufacturer. Network support and updating of system hardware and software is centrally performed. Access to a network operation center and accompanying data connections, along with technical support, hardware and software are leased to dealers by a single service provider. Alternately, the data connections, hardware, software and technical support may be provided by a single service provider independent of a network operation center.

Title: Hdtv up converter
Inventor: LE DINH CHON TAM
IPC: H04N7/01
Filed: 1999-04-01
Abstract: An electronic apparatus for converting a standard video signal having 59.94 fields per second into an HDTV video signal having 60.00 fields per second, by adding a number of video fields into each sequence of 1000 video fields. The apparatus detects the best moment for adding the new video field, so that the human eye does not perceive an abrupt change in the video image, by detecting the best motion conditions which occurs either when the image motion is high or very low. For adding the new video field, the apparatus uses an interpolation technique for creating two interpolated video fields which are inserted in place of one existing video field which is deleted. The apparatus also comprises a de-interlacer module for deinterlacing the 60 Hz video image, by using an advanced interpolation technique for calculating the missing video lines. The proposed technique involves directional interpolations of the missing lines pixels in various directions and selection of the best interpolation direction for the creation of each pixel of the missing video lines. The corresponding de-interlacer apparatus comprises a novel edge direction detector which performs the mentionned interpolations in all interpolating directions and then selects the best direction for performing the interpolation for each interpolated pixel, based on the quality of the performed interpolations.
