Patent CA-2247039-C (CA)
Title: Voie ferree, traverse et element de recouvrement pour l'espace situe entre les traverses
Inventor: UNBEHAUN OLAF
IPC: E01B5/00
Filed: 1997-02-17
Granted: 2006-09-12
Abstract: L'invention concerne une voie ferrée comportant un lit de ballast (10), des traverses (12) placées sur ledit lit de ballast et des rails (14) fixés sur les traverses. Les traverses sont placées très proches les unes des autres, mais sans contact, avec un espace entre elles et définissent des galeries d'évacuation des eaux transversales au sens longitudinal de la voie, qui servent à évacuer latéralement l'eau. Les espaces situés entre les traverses peuvent être recouverts d'éléments de recouvrement (142) ou les traverses peuvent se chevaucher sans contact. La couche de forme est ainsi maintenue hors de portée de l'eau et la stabilité de positionnement de la voie est augmentée. Les travaux d'entretien indispensables, tels que le bourrage, le nettoyage et l'arrachage des mauvaises herbes sont de ce fait réduits ou deviennent superflus.
Patent CA-2251490-C (CA)
Title: Two-piece rail seal clip and tool for installing same
Inventor: WHELAN CHRISTOPHER
IPC: E01B21/00
Filed: 1998-10-22
Granted: 2004-02-03
Abstract: A clip for securing a rail seal element to a rail includes a generally L- shaped first clip member having a clamping arm and an elongate connector arm extending from one end of the clamping arm and capable of passing under the rail; a second clip member removably slidable on the connector arm; and a locking mechanism capable of releasably locking the second clip member against sliding movement along the connector arm. In use, the second clip member is removed from the connector arm so that the connector arm can be passed under the rail with minimum disruption of the ballast. The second clip member is then slid back onto the connector arm, and the assembled clip then oriented so that the rail and the rail seal are positioned between the clamping arm and the second clip member. The second clip member is then slid on the connector arm toward the clamping arm so as to tightly press the rail and rail seal therebetween. Finally, the second clip member is locked onto the arm to prevent the clip from releasing the rail and rail seal. A tool for setting the clip includes a lever arm, and cam body and a pivot pin mounted on a nose of the cam body. By this means, movement of the second clip member toward the clamping arm is caused by inserting the pivot pin into a tool notch on the first clip member and thereafter pivoting the tool, about the pivot pin, toward the clamping arm. Subsequent pivoting of the tool away from the clamping arm causes the locking mechanism to automatically engage to prevent the second clip member from moving away from the clamping arm.

Abstract: The rivet includes a rivet body and a rivet shaft. The rivet shaft includes a shank with a head and an oval boss at opposite ends of the shank. The rivet body includes a circular flange with expandable arms extending therefrom with an oval aperture therebetween. The oval boss passes through the oval aperture and into cam grooves on the inner surface of the expandable arms. The oval boss, with its major axis positioned between the expandable arms, expands the arms apart into an installed position without the need for rotating the shaft subsequent to insertion. By turning the shaft one quarter turn after reaching the installed position, the minor axis of the oval boss is positioned between the expandable arms and the arms collapse to the uninstalled position. Additionally, complementary ramps and sheer faces on the lower surface of the head an within the countersunk nest surrounding the oval aperture inhibit relative clockwise rotation of the head in the installed position and urge the head upwardly from the flange in the uninstalled position.

Abstract: A self-compensating support skate (46) for an annular hydraulic ram (15) mounted in the front stationary platen (10) of a "two-platen" injection molding machine (1) is disclosed. The hydraulic ram (15) fits into a central bore (22) in the stationary platen (10) and connects directly to a relatively thin die platen (11) that provides a mold mounting surface. The purpose of the skate (46) is to prevent movement (tilting) of the die platen (11) and the resulting misalignment with the movable platen (20) when the mold (30) is attached. The skate (46) is adjusted during assembly to compensate for the tolerance stack-up in the ram assembly. The "zero" clearance is maintained by disc springs (56) within the skate (46) that compensate for the expansions and contractions of the large diameter parts due to temperature variations. The die platen (11) is held in the aligned position by contact with the lower tie rods (7).

Abstract: A transparent port which maps continuous format signals of an arbitrary rate into frames of a pre-selected single common rate, is provided with a programmable link termination/instigation, for example a FPGA (Field Programmable Gate Array). The port identifies the rate of the continuous signal, recognizes its protocol and the FPGA is configured accordingly. FPGA performs framing, counts errors, does code conversion, corrects parity and performs any other performance monitoring specific to the protocol.      In this way, the continuous format signal may be carried transparently as a tributary of e.g. a SONET (Synchronous Optical Network) network, and the performance parameters for the previous section, such as the previous section fail, may be reported to the far end.

Abstract: In order to simply and safely transport a sample of semen, the semen is mixe d and diluted with a dual sugar (sucrose and glucose) extender in a ratio of up to 10:1 (v/v) by inducting the semen into a semen storage device, e.g., a large volume syringe, having extender therein and optionally disposed within a form-fitting, radiation blocking, sleeve. The semen storage device is placed in a support member located on the floor of a rigid foamed plastic container and covered with a thermoregulating plate also made of a rigid foamed plastic. A refrigerant pack with solid foam coolant is placed on top of the thermoregulating plate, and the container is closed using a lid having a central boss that fits snugly into the mouth of the container, and further has a continuous ridge that fits into a recess formed in the upper edge of the container. The closed container is then placed in a light weight double-walled cardboard box that exhibits considerable structural strength, increases the insulation, absorbs ambient moisture and protects the rigid foamed plastic container during transit. The cooling rate achieved by the present invention is no more than about 0.20 .degree.C/min, preferably about 0.10 .degree.C/min, and most preferably abou t 0.01 .degree.C/min, over a temperature range of about 38 .degree.C toabout 5 .degree.C, preferably from about 15 .degree.C to about 5 .degree.C. The optimum transport temperature of the semen sample during transport is preferably about 5 .degree.C to about 10 .degree.C, most preferably about 7.5 .degree.C to abou t 8.5 .degree.C.
