Patent CA-2504474-C (CA)
Inventor: HEIZER CHARLES K
IPC: F01C1/08
Filed: 2003-10-28
Granted: 2008-09-09
Abstract: A screw rotor device has a pair of intermeshing rotors (14, 16) that are rotatably mounted in a housing around a pair of axes (26, 28). The cross-sectional shape of the rotors can be identical, i.e., twin rotors, or the rotors may have different cross-sectional shapes, i.e., a male and female.  Generally, the screw rotor has an identical number of threads and the twisting of the cross-sectional shape along the respective rotor axes results in a helical shape for each rotor that intermeshes with the other rotor (14, 16).  Accordingly, the rotors (14, 16) can be referred to as having intermeshing helical element pairs (34, 36). In several aspects of the invention, the helical element pairs can be, in the alternative or in any combination, a phase-offset thread and a corresponding phase-offset groove, a pair of single-pitch buttress threads (50), or a pair of single-pitch concave/convex threads.

Abstract: La présente invention concerne un système de bouchon du type pour boire à petites gorgées qui peut être fixé sur un récipient à col de sorte que la condensation ne s'accumule pas sur le joint en forme de disque. Ledit système comprend un moulage unitaire (1) conçu pour définir un sur-bouchon amovible (4) et une jupe (9) qui vient en prise au moins avec le récipient. Un élément d'insertion (2) et un joint en forme de disque (17) sont disposés dans le moulage (1), et un élément de type buse (3) situé au-dessus du joint, passe à travers l'élément d'insertion tout en pouvant se déplacer par rapport à celui-ci. Hors situation de distribution, l'élément de type buse (3) et l'élément d'insertion (2) servent de fermeture. En situation de distribution, un passage de sortie de liquide est formé entre l'élément de type buse (3) et l'élément d'insertion (2). L'élément de type buse et l'élément d'insertion, lorsqu'ils sont en situation de non distribution ou considérés comme étant en situation de non distribution, définissent avec le moulage un espace complètement fermé autour d'une partie de l'élément de type buse. Lorsqu'ils sont en situation de distribution ou considérés comme étant en situation de distribution, le moulage et le joint en forme de disque entourent complètement l'élément de type buse.

Abstract: A portable truck dump comprises a conveyor system mounted on an elongate frame to transport material from a first end of the frame to a second, opposite end of the frame. A grate is positioned over the conveyor system and is supported by first and second sides of the frame. A ramp extends generally perpendicular to the frame on each side of the frame next to the grate to provide a drive-over access for a material transport vehicle to deposit its load over the grate and onto the conveyor system. A first end of each ramp immediately adjacent to the frame is pivotally connected to the frame to allow the frame to be articulated towards the grate. A second end of each ramp spaced from the frame is supported above but in close proximity to the ground. A support frame is associated with each ramp to provide a barrier along the ground adjacent to and at a level of the second end of each ramp. The barrier supports an earthen ramp which enables the material transport vehicles to drive onto and over the ramp to deposit material over the grate. The support frame maintains the integrity of the earthen ramp when the ramps are articulated towards the grate. The support frame may also provide a support surface adjacent to the ground for supporting the second end of each ramp.
