Title: Vehicule sur rails pour le chargement et le dechargement de traverses
Inventor: MADISON HARRY
IPC: E01B29/06
Filed: 1997-12-11
Abstract: L'invention concerne un véhicule (10) d'entretien de voies ferrées servant à remplacer des traverses (14) usées par des nouvelles (16). Des traverses (14) usées sont ramassées et stockées dans des wagons-tombereaux (60, 62) découverts, avançant de préférence longitudinalement. De nouvelles traverses (16) sont déchargées simultanément des wagons-tombereaux (60, 62) pour être réparties le long de la voie (18). Des véhicules (34, 48A, 48B) de transport de traverses à boudin de roue, tels qu'un transport de grue mobile et de pince à paquets, se déplacent sur des rails (34) situés au sommet des wagons-tombereaux (60, 62) afin de déplacer des traverses usées (14) et de nouvelles (16) traverses entre des dispositifs (20, 40) de ramassage et de répartition et les emplacements respectifs de stockage et de déchargement. Les espaces entre les wagons sont pontés par des sections (36) de rails télescopiques suspendus. La distance de déplacement entre l'emplacement de stockage ou de déchargement et les postes de ramassage ou de répartition change avec le temps. Pour améliorer l'efficacité du système, au moins une corbeille (50) de stockage temporaire intermédiaire est déplacée le long des wagons (60, 62), les véhicules (38, 48A, 48B) pouvant passer sur celle-ci. La corbeille (50) est utilisée de préférence avec un troisième véhicule (38) de transport de traverses pour contribuer à la manipulation des paquets et raccourcir le déplacement du premier (48A) ou du deuxième (48B) transport de ramassage ou de distribution. La corbeille (50) est particulièrement utile pour accumuler un paquet de nouvelles traverses (16) en vue d'un ramassage par un véhicule (38) de transport de préhension de paquets. Le véhicule (10) peut être limité au ramassage et au stockage de traverses (14) usées laissées sur les rails (18) par un extracteur (200) de traverses précédent, et au déchargement de nouvelles traverses (16), ou peut également incorporer des dispositifs (200) d'extraction et/ou d'insertion de traverses.

Filed: 1998-10-30
Abstract: A developing device used in an image forming apparatus has a developing roller at a lower opening of a toner hopper, and the developing roller contacts a photosensitive drum to form a developing portion therebetween. The hopper stores nonmagnetic toner and is provided with a toner stirring member and a toner feed roller being in press-contact with the developing roller in a lower part of the hopper. A doctor blade contacts a circumferential surface of the developing roller on an upstream side of the developing portion in a rotation direction of the drum. A conductive scooping sheet contacts the circumferential surface of the developing roller on a downstream side of the developing portion. A residual toner not used to develop a latent image on the drum and left on the developing roller is passed under the sheet into the hopper with the rotation of the developing roller. A sheet bias voltage ranging from OV to -250V is applied to the sheet, so that an attaching force of the residual toner to the developing roller is weakened so that the residual toner can be easily removed by the feed roller.

Patent CA-2254982-A1 (CA)
Inventor: HART JOHN
IPC: E21B36/00
Filed: 1998-11-30
Abstract: This invention relates to protectors which protect well casings against frost heaving forces. In the invention, a well casing protector having a cavity extend though its entire length is provided. The cavity is shaped to slide over the end of a well casing. The well casing protector is able to slide up or down along the well casing.  Once in place, the well casing protector surrounds the portion of the well casing extruding from the ground (except for the very top portion of the well casing) and also the portion of the well casing in the portion of the ground just beneath the ground surface, which freezes. Because the well casing protector is slidable along the well casing unit, when the ground freezes, and frost heaving forces are exerted, the frost will adhere to the well protector, and move it rather than the well casing, eliminating any movement of the well casing.

Patent CA-2279115-A1 (CA)
Inventor: FEUER HENRY O JR
IPC: F16C41/00
Filed: 1999-07-29
Abstract: These and other objects of the present invention are achieved by inserting electrically conductive rings and a bearing into a mold before a slip ring body is injection molded. During the injection molding process, the rings and the bearing are partially encapsulated by the injected plastic and retained. Plastic is prevented from entering the race of the bearing by using a pair of additional plastic inserts which prevent plastic from entering the bearing race. When the injected plastic cools, the plastic shrinks and compresses the bearing thereby preventing axial movement. Wires attached to the rings are also encapsulated by the plastic material during the injection molding process.

Title: Method and apparatus for determining the quality of cereals
Inventor: BOHLIN LEIF
IPC: G01N3/00
Filed: 1997-11-14
Abstract: In a method for assessing the quality of cereals, a dough containing the type of cereal which is to be assessed is deformed. Subsequently the dough is let relax. During the relaxing the stress in the dough is measured. On the basis of the stress, one or more relaxing parameters are determined which are used in a predetermined calculation model for assessing the quality. In the calculation model, mixing parameters, which are determined during the deformation, can also be used. A new such parameter which correlates well with cereal quality is the build-up parameter, which is determined on the basis of the difference in the stress in the dough when it has absorbed all the liquid which is added in preparing the dough and the maximum stress in the dough during the deformation. An apparatus for quality assessment is also disclosed.
