Patent CA-2517967-C (CA)
Title: Trailer operable in lowered and raised transport positions
Inventor: TRUDEAU ANDRE
IPC: B62D63/06
Filed: 2005-09-01
Granted: 2012-11-13
Abstract: A trailer includes a deck frame which can be supported in a lowered transport position in which the deck frame is spaced above the ground below a height of the wheels corresponding to a deck between configuration and a raised transport position in which the deck frame is spaced above the ground substantially at or above the height of the wheels corresponding to a deck over configuration. Consumers are thus only required to purchase a single trailer to meet the advantages of both trailer configurations. Load supports, independent of a lift mechanism of the trailer, are provided in addition to the linkage which controls displacement of the deck frame between the two positions to ensure that the deck frame is supported on the wheels in a manner so as to safely bear a load on the deck frame in both the lowered and raised positions.

Title: Manufacture of top plate for an elastomeric rail fastening assembly
Inventor: SCHONSTEIN PETER JULIAN
IPC: E01B3/24
Filed: 2004-04-01
Granted: 2012-05-15
Abstract: A top plate (5) for an elastomeric rail fastening assembly has a downwardly tapering lower wall (22) terminating in an inwardly-directed lip (25) defining a mouth (26) leading into a well (24). The cavity of the well (24) extends upwardly to provide the interiors of rail-holding mounts (10) between which a bottom flange of a rail may be located. The mounts (10) have open-ended sockets (11) for receiving spring clips used to hold the rail in position between the mounts (10), and the sockets (11) and well (24) communicate with one another. This form of top plate allows less metal to be used for its construction, requires less dressing after casting, and, precisely locates the sockets with respect to one another.

Abstract: L'invention concerne une pièce très résistante, dont la résistance à la fragilisation par hydrogène et la résistance après formage sous haute température sont excellentes. Elle concerne également un procédé pour la fabrication de celle-ci. Dans un four de réchauffage, avant le formage, l'atmosphère est réglée sur une fraction volumique d'hydrogène = 10 % et/ou un point de rosée = 30 °C. En conséquence, la quantité d'hydrogène qui pénètre dans une feuille d'acier pendant le chauffage est réduite. Après le formage, on réalise séquentiellement un durcissement par trempe en filière et un réusinage. Comme procédé de réusinage, on peut citer le cisaillement suivi d'un re-cisaillement, ou le formage par compression d'une partie au bord découpé ; le poinçonnage avec une lame de coupe ayant une partie dégradée où la largeur de la base de la lame diminue en continu ; le poinçonnage avec un outil ayant une lame incurvée avec une configuration saillante à l'extrémité de la partie de la lame de coupe, la lame incurvée ayant une partie d'épaulement de rayon de courbature donné et/ou d'angle donné ; le découpage par fusion, etc. En conséquence, la contrainte résiduelle de traction après le poinçonnage est réduite et la performance de résistance à la fragilisation par hydrogène est améliorée.

Granted: 2014-10-21
Abstract: The present invention relates to a process for the separation of gluten and starch from wheat flower, wherein in a first step the wheat flour is converted into a dough having a moisture content of less than 50 wt%, based on dry weight of the flour. The dough is in a subsequent step subjected to an essential simple shear flow with a shear stress of at least 1 kPa and a specific mechanical energy input of at least 5 kJ/kg per minute processing time to obtain a processed dough. It is preferred that the apparatus used for performing this step comprises a reactor of the cone-and-plate type or the cone-cone-type wherein an absolute velocity profile across the conical gap is present. In a final step, the processed dough is separated into a gluten enriched fraction and a starch enriched fraction. The gluten enriched fraction is very suitable for bakery applications.

Abstract: A transmission gearbox for a rotary-wing aircraft includes a main gearbox and a variable speed gearbox in meshing engagement with the main rotor gearbox.  The variable speed gearbox permits at least two different RPMs for the main rotor system without disengaging the engine(s) or changing engine RPMs. The variable speed gearbox includes a clutch, preferably a multi-plate clutch, and a freewheel unit for each engine. A gear path drives the main gearbox in a "high rotor speed mode" when the clutch is engaged to drive the main rotor system at high rotor rpm for hover flight profile. A reduced gear path drives the main gearbox in a "low rotor speed mode" when the clutch is disengaged and power is transferred through the freewheel unit, to drive the main rotor system at lower rotor rpm for high speed flight. The variable speed gearbox may be configured for a tail drive system that operates at a continuous speed, a tail drive system that changes speed with the main rotor shaft or for no tail drive system.
