An alternative embodiment of the cutting system includ es at least one channeling wall (200) that cooperates with a mower deck (100) to form a tapered channel (202) that tapers in the direction of blade (120) rotation. A baffle assembly (130) is disposed in the narrow portion of the channel (202) such that clippings are channeled int o the assembly (130) where they may be recut.
Patent CA-2259131-A1 (CA)
Inventor: BOUVIER MICHEL
IPC: G01N33/94
Filed: 1997-06-30
Abstract: This invention is a new method of assaying compounds that modulate the activity of G protein-coupled receptors based on measurement of changes in the relative proportions of monomeric to multimeric receptor polypeptides. More specifically, techniques are described herein which permit the prediction of the pharmacological efficacy of drug candidates based solely on the ability of the candidate compounds to alter the ratio of receptor monomer to homo-oligomeric forms of the receptor. This method provides a novel means of assaying compounds as potential therapeutic drugs at G protein-coupled receptors which is greatly simplified and more generally applicable than existing methods.

Abstract: The invention relates to a method and device for checking if data records have been created correctly and fully in telecommunication systems. An automatic review system enables customer behaviour oriented communications to be carried out in the telecommunication system which is to be checked. Communication parameters in calling and called stations are recorded independently from each other and the network, reviewed and filed as a reference data record.      Communication data records which are automatically self-recorded in the telecommunication network are subsequently verified on the basis of reference data records filed in the review system. The invention is characterized in that the system creates its own reference data records required for verification. These data records are 100 % qualitatively reviewed, real communication data. The review includes all computationally relevant parameters. Defective communication data records are analysed, including telecommunication and connection data recorded by the review system and telecommunication devices, along with signalling and review information files.

Abstract: Le système de suspension et d'insonorisation est du type dans lequel un revêtement de finition d'une maison ou d'un édifice est retenu à une surface solide d'infrastructure au moyen d'une pluralité de cylindres de caoutchouc pourvus chacun d'une cavité ouverte s'étendant dans une direction axiale. Chaque cylindre est attaché à la surface solide au moyen d'une bande de suspension pourvue de deux extrémités opposées, qui est glissée dans la cavité du cylindre et dont les deux extrémités sont repliées sur la surface solide et y sont attachées. Le revêtement de finition est attaché à des barres de suspension qui sont elles-mêmes attachées aux cylindres à l'aide d'attaches passant dans les cavités du cylindre. Selon l'invention, les cavités des cylindres de caoutchouc sont axialement décentrées et les cylindres sont orientés lors du montage de façon à ce que les cavités décentrées soient plus proches de la surface solide que des barres de suspension. De plus, les attaches sont constituées chacun d'une autre bande de suspension façonnée et dimensionnée pour recevoir et supporte une des barres de suspension, cette autre bande de suspension étant en forme de U et comprenant une portion centrale et deux côtés opposés perpendiculaires à la portion centrale, chaque côté ayant au moins un trou et une épingle façonnée et dimensionnée pour être insérée dans les trous des côtés de l'autre bande tout en passant dans la cavité d'un des cylindres. Ceci a l'avantage de minimiser les chances de contact entre, d'une part, les bandes de suspension servant d'attache des cylindres de caoutchouc à la structure de l'édifice, et d'autre part, les moyens servant à l'attache des barres de suspension aux cylindres de caoutchouc. Ceci a également l'avantage d'assurer une meilleure insonorisation, en fournissant une couche de caoutchouc plus large entre les barres de suspension et leur attache.

Inventor: CARTER THURMAN B
IPC: E21B17/07
Filed: 1998-05-01
Abstract: This invention relates to an apparatus for controlling the motion of a string of tubulars in a wellbore. In milling a tubular with a downhole mill, using too much weight on the mill and/or advancing the mill too quickly can result in inadequate milling, inefficient milling, and damage to the mill, its associated equipment, and the item to be milled. In offshore milling operations, a mill lifted away from a tubular being milled, e.g.  by a swell at the water's surface that lifts a boat or barge from which the milling system is suspended, can be slammed back into the tubular being milled as the swell passes and the boat is effectively lowered. This is particularly undesirable.
