Abstract: An improvement is made to a torque splitting device employing hydraulic clutches so as to avoid any discontinuity in the control even when the properties of the actuating oil such as the pressure and temperature thereof deviate from standard values. For instance, when the oil temperature is low, the target value of the oil pressure for each of the clutches is modified to a lower value. Thus, it becomes possible to make less pronounced any delay in the response of the torque splitting device which may arise due to the sluggishness of the oil as it flow out of the clutch cylinder. The oil pump is typically actuated by a member rotating at a speed proportional to the vehicle speed, and the pressure output of the pump may be inadequate in a low speed range. In such a case, the target value is again reduced so as to reduce any abrupt change in the property of the torque splitting device when the vehicle is accelerated from a low speed. Because the pressure output of the pump normally drops as the oil temperature rises, it is desirable to take into account the oil temperature in this control action as well.

Abstract: An automatic welder is used in an internal welder unit which travels along the interior of a pipeline and welds the abutting ends of the pipe segments together.  The automatic welder has a carriage assembly that contains a laser source for producing a laser beam, first and second line-up clamp assemblies for aligning the respective abutting ends of the pipe segments together, at least one laser beam conductor, or alternatively a reflecting surface positioned between said first and second line-up clamp assemblies along the axis of said beam, for directing said beam to the abutting ends of said first and second pipe segments, and a drive for rotating the reflecting surface around the axis of said beam to direct the beam to the abutting ends of said pipe segments for welding said pipe segments together. The automatic welder can also be configured as an external welder in which the automatic welder carrying a laser source is carried on a track mounted on the outside of the pipeline. As the external welder orbits around the pipeline, the laser source generates a laser beam which is directed at the junction of the abutting ends of the pipe segments for welding them together. Arc and laser beads can be combined to form a composite welding joint.

Abstract: L'invention concerne une plaque ou un cylindre filtrant présentant une surface filtrante (11) pour séparer des particules acceptées et des particules rejetées, la surface comprenant une pluralité de macro-rainures parallèles (22) et une pluralité de micro-rainures parallèles (24) formées dans chaque macro-rainures, dans une direction généralement perpendiculaire à la direction d'écoulement. Les macro-rainures induisent des contraintes de cisaillement dans les particules rejetées et les empêchent de former un tapis sur la surface du tamis. Les micro-rainures induisent une micro-turbulence dans la pâte au niveau des ouvertures (27) du tamis, ce qui améliore le passage des particules acceptées à travers les ouvertures. Chaque micro-rainure dans la macro-rainure est plus éloignée de la surface d'acceptation (12) quand on se déplace dans la direction d'écoulement. Le contour de chaque micro-rainure comprend de préférence une paroi amont (39), une paroi aval inclinée (40) et une dépression (41) entre les deux. Les ouvertures du tamis sont aménagées dans la dépression. Il est possible d'effectuer un tamisage avec un taux de rejet d'environ 3-10 % pour une efficacité d'élimination des débris supérieure à environ 85 %.

Abstract: A tube which circumferentially distends from its initial circumference upon the appli- cation of a circumferentially distending force such as applied by an internal pressure, and which exhibits minimal recoil following the re- moval of the circumferentially distending force. The tube preferably has a second circumfer- ence larger than the initial circumference which remains substantially unchanged by further in- creasing force once it has been achieved. Be- cause of the distensible circumference and min- imal recoil of the tube, the tube is useful as a liner for pipes and vessels and particlarly for pipes and vessels having irregular internal sur- faces towhich the tube can smoothly conform. The tube is preferably made from porous PTFE with thin walls, in which form it is particularly useful as a liner for both living and prosthetic blood vessels and to line anastomoses between living and prosthetic blood vessels.

Title: Rock bit cutter retainer
Inventor: PRICE RANDALL R
IPC: E21B10/08
Filed: 1998-07-28
Granted: 2006-08-29
Abstract: A novel split threaded ring bearing member for rolling cutter drill bits with at least a portion of its threads having a different pitch than its mating threads is disclosed. The pitch difference is designed so that the threaded ring can be seated or otherwise located precisely with respect to the other bearing elements within the drill bit to effectively control the axial displacement of the rolling cutter on the bearing spindle within a given tolerance range. Upon assembly, the difference in thread pitch causes the opposite, opposing mating thread flanks to engage, effectively applying a tensile or compressive force to a portion of the threaded ring bearing member, which gradually increases as the assembly is tightened. The result is an improved rolling cutter drill bit with a threaded ring cutter bearing system with excellent resistance to back-off which will not allow significant radial movement between the engaged threads, even if some back-off of the threads occurs.

Title: A process and apparatus for tracing software entities in a distributed system
Inventor: STORY ROD
IPC: G06F11/34
Filed: 1998-07-28
Granted: 2002-06-25
Abstract: The invention relates to a process and apparatus for tracing software entities, more particularly a tracing tool providing   tracing   capabilities   to   entities   in   an application.    The  object-tracing  tool  provides  software components   to   allow   tracing   the   execution   of   an application.  Tracing  software  entities  is  important  for software  developers  to  permit  the  quick  localization of errors and hence facilitate the debugging process.   It is also useful for the software user who wishes to view the control  flow  and perhaps  add  some  modifications  to  the software.   Traditionally, software-tracing tools have been confined to single node systems where all the components of an application run on a single machine.   The novel tracing tool presented in this application provides a method and an apparatus  for tracing software entities  in a distributed computing environment.   This  is done by using a network management  entity to  keep  track of  the  location of  the entities in the system and by using a library of modules that can be inherited to provide tracing capabilities.   It also uses a log file to allow the program developer or user to  examine  the  flow,  the occurrence  of  events  during  a trace  and  the  values  of  designated  attributes.   The invention also provides a computer readable storage medium containing a program element to direct  a processor of a computer to implement the software tracing process.

Abstract: The present invention is directed toward providing a secure method to access data when the user has lost or forgotten the user password (261). In accordance with the invention and in a system where decryption of an access key (232) will give access to data, two encrypted versions of the access key are created (236, 270). A first version (236) is formed using a key (264) formed with the user password. A second version (270) is formed using a public key (266) from a public-private key pair. Generally, data access can be had by decrypting the first encrypted version (236) of the access key (232) with the password key (264).  However, if the password (261) is forgotten, access to data can be accomplished by decrypting the second encrypted version (270) of the access key (232) with the private key (280) from the public-private key pair. One embodiment of the invention requires the private key (280) to be stored at a remote site and for decryption using the private key to take place at the remote site. In this manner the user can gain access to data without significantly compromising the data security.
