Title: Method and apparatus for welding with a trigger hold
Inventor: ALTEKRUSE KENNETH C
IPC: B23K9/12
Filed: 2000-03-07
Abstract: A method and apparatus for welding is disclosed.      The method includes sensing the status of a trigger between an on position and an off position. A system latch is set or released based on the trigger status and the latch status. The system latches on when the trigger is held for a predetermined time (and the latch was previously off).      The latch is released when the trigger is pulled and released when the latch was previously on. When the latch is off, pulling the trigger turns the system on, and releasing the trigger before the predetermined time turns the system off. The latch may also be released when welding current drops below a threshold. The time might not start until after welding current is flowing. A welding wire feed speed control potentiometer on a torch is also disclosed.      The range of the torch potentiometer is from a minimum to a value dependent on the control panel welding wire feed speed. A run-in wire feed speed control is also disclosed.      The range of the run-in wire feed speed is from a minimum to a value dependent on the control panel or torch welding wire feed speed.

Abstract: A hydraulic coupling (10) for use in motor vehicle driveline applications to limit speed differentiation and transfer drive torque between two rotary members. The hydraulic coupling includes a multi-plate clutch assembly (22) operably connecting the two relatively rotatable members, and a sealed actuator assembly (20) for actuating the clutch assembly (22) in response to the magnitude of speed differentiation between the two rotary members. The actuator assembly (20) includes a hydraulic pump (24) and a piston (70) which are sealed relative to the clutch assembly (22). The sealed actuator assembly (20) includes an internal recirculation path for supplying hydraulic fluid retained therein between a low pressure supply chamber (130) at the inlet side of the hydraulic pump (24) and a high pressure piston chamber (72) provided at the discharge side of the hydraulic pump (24). Hydraulic pressure in the piston chamber (72) controls the magnitude of the clutch engagement force exerted by the piston (70) on the clutch assembly (22). As a further feature, the recirculation path includes a flow restrictor (146) which provides a bleed flow path for supplying high pressure fluid from the piston chamber (72) to the supply chamber (130) following cessation of the pumping action to release the clutch assembly (22).

Title: Mono-roc, poly-roc et deco-roc

IPC: E01F9/594
Filed: 2000-06-27
Abstract: Nous savons que les roches naturelles sont excessivement lourdes à déplacer. Nous savons également qu'il est très onéreux de se procurer une roche naturelle puisque les coûts de transport et d'installation sur le site sont très élevés en raison des difficultés que cela représente.   La présente invention se veut une alternative d'aspect tout à fait naturel tout en éliminant les problèmes et coûts reliés à l'achat/installation d'une roche naturelle.   La seule autre alternative connue à ce jour à la roche naturelle est celle fabriquée de fibre de verre. Cette dernière cependant est toujours lourde et demande un équipement de transport adéquat et est également coûteuse.   L'invention des MONO-ROC, POLY-ROC et DÉCO-ROC se veut la solution par excellence pour contrer tous obstacles rencontrés jusquà ce jour, tant au niveau du poids que du coût.   Nous pouvons en effet supprimer les faits indésirables soit poids excessif et coût élevé en ayant recours à la présente invention.  Très légères lorsque vides, elles se transportent et se déplaceront ultérieurement aisément, puisqu'il suffira de les vider afin de les déplacer lorsque le besoin ou le désir sera exprimé et de les remplir à nouveau au nouvel emplacement. La matière de remplissage suggérée est l'eau, bien que le sable ou le ciment pourront être utilisés lorsqu'une installation permanente sera souhaitable et/ou préférable.   Le remplissage à l'eau se fait en peu de temps, ne cause aucun frais, rend la roche stable et permettra tout de même la vidange, le déplacement lorsque requis ou souhaité. Il suffira de remplir à nouveau lorsque le nouvel emplacement de la roche sera défini.   Les roches inventées seront toutes munies d'un orifice de remplissage et d'un orifice de vidange, tel que montré à la page 4 de ce document.   Aucun équivalent n'ayant cette efficacité, cette versatilité, cette mobilité et cette légèreté n'existe sur le marché actuellement.

Title: Method for establishing optimal intermediate caching points by grouping program elements in a software system
Inventor: DUTTA RABINDRANATH
IPC: G06F17/30
Filed: 2000-09-07
Abstract: A set of program elements (e.g., transcoders) are grouped together as an administrative unit. Instead of caching the individual outputs of each program element, preferably only the aggregate output of the set of program elements, taken as a whole, is cached. The inventive technique enables the effective re-use of intermediate content. In an illustrative client-server based implementation involving a transcoding service located at a server, the cached information may be shared across multiple server instances to obviate redundant processing.  With the present invention, a caching mechanism in a complex software system may be extended in a user-configurable manner by setting up optimal intermediate caching points that are defined by groups of programs used in long computations.
