Abstract: A slip yoke assembly for a vehicle drive train assembly includes a yoke shaft having a shaft portion with a plurality of external splines formed thereon. A hollow transition member having a plurality of internal splines is connected to the yoke shaft for rotational driving movement, yet is permitted to move axially relative thereto. A hollow weld ring is secured to the yoke shaft for rotational movement therewith. The weld ring extends co-axially about the splined connection between the transition member and the shaft portion of the yoke shaft and provides an exterior surface to which one or more balance weights may be secured. The weld ring also provides an annular space to retain a quantity of lubricant for the splined connection. A flexible convoluted boot is provided to seal the splined connection between the transition member and the shaft portion of the yoke shaft. A first end of the boot is secured to the weld ring, while a second end of the boot is secured to the transition member. The boot prevents contaminants from entering into the splined connection between the transition member and the shaft portion of the yoke shaft. A sleeve cup is also provided to seal the splined connection between the transition member and the shaft portion of the yoke shaft. The sleeve cup includes a circular body portion having a relatively short, axially extending flange portion. The circular body portion of the sleeve cup extends over the open end of the transition member to prevent contaminants from entering into the splined connection between the transition member and the shaft portion of the yoke shaft through the interior of the driveshaft section. The flange portion of the sleeve cup is frictionally engaged between the inner cylindrical surface of the driveshaft section and the outer cylindrical surface of the transition member to retain it in position during use.

Title: Device for cauterizing horn buttons and horn stumps in cattle
Inventor: HANSEN DONALD C
IPC: A61B18/06
Filed: 1997-03-03
Granted: 2006-05-23
Abstract: A flammable gas heated cauterizing device for use in cauterizing the horn stumps in older cattle as well as removing the horn buttons from young calves.  A propane torch having a burner tube is utilized to heat a cauterizing device fabricated from surgical stainless steel. A first embodiment, for cauterizing larger horn stumps, comprises a torch attachment tube spot welded to a cauterizing tip having a flat cauterizing face with rearwardly extending frustoconical tubular sidewalls. A  second embodiment, for cauterizing horn buttons, is identical to the first embodiment but utilizes a concave cauterizing tip. The invention heats up much faster and to a much higher temperature than the prior art devices, thereby making the cauterizing process much quicker and less painful for the animals.

Abstract: A universal joint assembly includes a cross having a body and at least a pair of outwardly extending opposed trunnions. The trunnions define a trunnion axis. A bearing cup is rotatably mounted on each of the trunnions. A yoke includes a pair of opposed arms wherein each arm has an opening formed therethrough and aligned with the other arm opening to receive one of the bearing cups. Each of the openings defines a cylindrical surface having a cylindrical groove of a predetermined width formed therein. The yoke defines a yoke axis. A snap ring of a predetermined thickness is inserted into each of the grooves to retain the bearing cups on said trunnions. The width of each of the grooves is greater than the thickness of the snap rings to permit the cross to be selectively positioned with respect to the yoke. A staking operation fixes the position of the cross with respect to the yoke so that the cross center of gravity is aligned with the yoke axis.

Granted: 2005-08-16
Abstract: L'invention concerne un assemblage (10) constituant un outil pour labourer la terre, muni d'une dent (18) qui est montée de manière pivotante pour éliminer les obstructions dans le sol. Le mouvement qui déplace la dent de sa position normale est opposé par la force d'un vérin (22) hydraulique. La force que doit nécessairement exercer la dent sur les forces opposantes du vérin (22) est initialement élevée mais elle est réduite face à un mouvement prédéterminé de la dent (18) et face à une rétraction prédéterminée du vérin (22). Cela permet à la dent (18) d'éliminer les grosses obstructions sans endommager ladite dent (18). L'invention présente deux positions alternatives de soupapes; une à l'intérieur du vérin (22), où l'embout s'étendant dans le cylindre du vérin agit avec un manchon dans le piston du vérin, et une à l'extérieur comprenant une came agissant sur une soupape dans un canal d'alimentation de fluide. L'invention présente également un circuit hydraulique muni d'un amplificateur de pression.

Abstract: A method and apparatus for operating a set of resources (74-77) under the control of a secure processor, e.g., security module (50), having a command authentication means and a command execution means, to achieve secure contro l of the resources. The secure processor stores a set of command primitives (5 2) for functional control of the resources. A set of defined commands for invoking command primitives has either a secured command format including a command sequence ID, a command code, and a set of command data items or a no n- secured command format including a command code and a set of command data items. The secure processor stores a command set up table including command type flags to designate each command as a secured command or a non-secured command. An application program (61) running in an external device includes a plurality of the defined commands in either secured command format or the no n- secured command format and these are sent one at a time to the secure processor for execution. The secure processor looks up each received command in the command set up table, and if the command is a non-secured command it immediately executes associated command primitives. If the command is a secured command, the secure processor tests both its authenticity and regularity and only executes theassociated command primitives if the command passes both tests.
