IPC: E04H17/22
Filed: 1998-03-03
Abstract: A post assembly for supporting a fence, a sign or receptacle such as a mailbox. The post assembly comprises a ground penetrating rod having an enlarged head, a square, hollow, decorative body placed over the rod after the rod is forced into the ground, and a footplate. The enlarged head of the rod cooperates in close fit within the hollow body. A pin fractionally fits into openings formed in the body, interfering with the rod as the body is lowered aver the rod. The body is then employed as a driver to force the rod into the ground. when the rod is driven down to the point that the body contacts the footplate, the pin is removed from the body. The body then is lowered into abutment with the footplate. The openings of the body which receive the pin then align with a passage formed in the enlarged head of the rod. The pin as reinserted into the body, this time passing through the passage of the enlarged head of the rod. The rod and body axe thus interlocked. The footplate has prongs for engaging the ground, and a hole through which the rad passes and in which the rod is maintained upright. The rod and the prongs of the tootplate combine to secure the assembled post within the ground.

Patent CA-2294421-A1 (CA)
Inventor: TURK VITO
IPC: A01N63/00
Filed: 1998-06-18
Abstract: Equistatin, belonging to the type I repeated thyroglobulin domain, and known to be an inhibitor of cysteine proteases is found to also inhibit aspartic proteases with a different domain of the protein. The DNA encoding equistatin, and inhibitor or cysteine and aspartic proteases, is isolated from the sea anemone Actinia equina. The equistatin protein was found to be particularly active towards gut cysteine and aspartic proteases of a number of common insect pests of agricultural crops, such as Colorado potato beetle, com rootworn, leafminer fly and thrips. P41 invariant chain fragment, another member of this family with only cysteine protease inhibitor activity was equally active towards the cysteine protease complement as was found for equistatin.  Recombinant equistatin protein was found to be larvicidal against Colorado potato beetle and to strongly reduce fecundity of adult thrips. DNA  encoding equistatin and other proteins containing similar type I repeated thyroglobulin domains may be cloned into vectors and used to transform plants thus conferring reduced susceptibility to damage by plant pests that have thiol and/or aspartic proteases as digestive enzymes including insects and nematodes and particularly Coleopteran, Dipteran and Thysanopteran insects.

Filed: 1999-04-07
Abstract: The invention concerns a method for the application of lacquer to edges on plates and lists, especially of the porous type which are used within the furniture industry, where by changing the CAD reference dimension of the edge profile lacquer dosing unit it is possible to apply differentiated amounts of lacquer to predetermined areas. The invention also concerns a system for the application of lacquer to the egdes on plates and lists, especially of the porous type used in the furniture industry. Among other things, the system comprises one or more application rollers (9), possibly with a groove (10) in the surface of the individual roller (9) which can correspond to the edge profile (18) to which the lacquer is to be applied. The CAD reference can also be changed in the profile groove (10) of the application roller (9), or in both the roller (9) and the dosing unit (11). By using several units or application rollers (9) in succession, a particularly fine surface is obtained by allowing the application roller (9) which is placed last in the direction in which the work piece (18) is fed, to rotate in the opposite direction, whereby the excess lacquer is removed while at the same time a very well-defined thickness of lacquer is achieved. The method and the system are especially applicable in the lacquering of chipboards and similar porous plates which are not homogeneous.

Patent CA-2335022-A1 (CA)
Title: Method and apparatus in transmission of images
Inventor: LARSSON MATHIAS
IPC: H04N7/26
Filed: 1999-06-10
Abstract: An image (3) in digitized form shall be transmitted over a channel between a transmitter and a receiver. The channel has a limited bandwidth and the image has a less important background (R1) and also regions of particular importance, i.e. regions of interest (R2, Rn). The image is transformed into transform coefficients and compressed (21), and a mask corresponding to the regions (R1, R2, Rn) is defined in the transform domain (22). The transform coefficients are classified (23) and assigned to different segments (SG1, SG2, SGn) in accordance with the mask definition. These segments (24) are coded independently of one another to different degrees of accuracy, depending on the importance of corresponding regions (R1, R2, Rn) in the image (3). Coding results in sub-bit streams (25) which are linked together (26) with the image header (271, 272) to form a bit stream (27), which is sent to the receiver.  The receiver decodes the image header and the segment information and reconstructs the mask in the transform domain, including shapes and positions of the regions (R1, R2, Rn). The image is then recreated with the aid of the mask to desired degrees of accuracy in respective regions. It is possible to define several regions (R2, Rn) with different degrees of image quality, and only those parts of the image that are of interest need be decoded.
