Patent CA-2001814-C (CA)
Inventor: THIBODAUX PEGGY L
IPC: A61F5/04
Filed: 1989-10-30
Granted: 2000-05-16
Abstract: A brace for external fixation of long bone fractures which includes "T"-shaped member and cross-shaped elongate members, both of which are curved along a longitudinal axis to fit around the limb and which interlap to provide circumferential support. The two-piece, curved configuration concentrates the load applied to the limb over a smaller surface area and is, therefore, more effective at immobilizing the fractured bone while allowing access to the skin for wound management, surgery, and hygiene without removing the brace. The configuration also makes possible the adjustment of the brace at three independent points to provide for improved fit over a wider variety of sizes and shapes of limbs than previously available.

Granted: 2009-09-15
Abstract: Transdominant repressors of viral gene phenotypic expression derived from the rev gene product of HIV-1 or the rex gene product of HTLV-1 and corresponding mutated genes are described, having the capability of repressing the Rev function in HIV-1 and/or the Rex function in HTLV-I and HTLV-II. Transient gene expression analysis of a series of missense and deletion mutants has been used.     Some of the mutants found repress both the Rev and the Rex function and are thus active in more than one viral species.     Transdominant viral mutants represent a promising new class of anti-viral agents. Cellular expression of these transdominant inhibitors may be used in such therapeutic approaches as intracellular immunization in order to protect cells against the deleterious effects of viral, e.g.   HIV-1 infection.

Filed: 1991-02-25
Granted: 1994-05-31
Abstract: AN ARRANGEMENT FOR AUTOMATED TROUBLESHOOTING USING      SELECTIVE ADVICE AND A LEARNING KNOWLEDGE BASE Abstract Troubleshooting expert systems are generally embodied in software for the purpose of solving difficult problems in some narrow domain of expertise. The prior art describes certain mechanics for developing or generating rules. That process is commonly known as the knowledge acquisition process. Having acquired the knowledge, our new troubleshooting arrangement eliminates the prior art separation between the expert system knowledge acquisition process and the expert system utilization process. Our new arrangement also detects and classifies invalid actions or other errors of the user in a manner that allows for the non-human expert system to advise the human user. Our arrangement interactively communicates between a user and a troubleshooting system, generates a learning knowledge base, identifies an object being tested by the user, utilizes the learning knowledge base for troubleshooting the test object, and classifies the test object as faulty or not faulty. Our arrangement structures prior actions of the user as pairs of elements in a multi-branch tree in the learning knowledge base and the compares present actions of the user with the prior actions of the user. A current signal path is generated between a first input and a first output in the system under test. Then, it can be determined whether the test object belongs to the current signal path. Responsive to the comparison of the actions of the user andresponsive to whether the test object belongs to the current path, the skill level of the user can be classified into one of a plurality of skill levels. Responsive to the skill level classification of the user, the kind of troubleshooting advice to be given the user can be classified as to one of a plurality of kinds of troubleshooting advice and thereafter the advice can be communicated to the user. Further, the output of the test object can be measured and a new current signal path can be generated and re-generated for identifying a faulty object in the system under test.

Title: Method and apparatus for sensing the condition of casting belt and belt coating in a continuous metal casting machine
Inventor: GRAHAM THOMAS S
IPC: B22D11/06
Filed: 1991-11-27
Granted: 1995-01-17
Abstract: Method  and  apparatus  for continuously  sensing and monitoring the conditions of tensed flexible endless metallic casting belts and their insulative coatings in a continuous metal casting machine. The flatness of a casting belt is continuously monitored and thereby also the condition of its thermal  protective coating.  One  or more  non-contacting eddy-current sensing probes are placed in proximity to the reverse or coolant side of a belt for sensing and measuring the  distance  of  the  belt  from  the  probe  to  reveal irregularities in the flatness of the belt while it travels past the probe. A deficiency of insulative belt coating can cause  variations  in  belt  flatness  during  casting.  By monitoring such variations an operator of the continuous casting machine is alerted that the coating needs to be retouched  or  replaced without  interrupting  the casting process. Or such monitoring can alert the operator that the belt has become inherently not flat. In another embodiment of the invention a similar proximity sensing probe is utilized for the purpose of supplying an instant report of the initial entrance of molten metal into the casting cavity adjacent to a casting belt at the start of a cast. In this way, forward travel of the casting belt is initiated in synchronized relationship with introduction of the molten metal into the casting cavity by starting the forward belt motion at the appropriate instant before the entrained plug ("dummy bar") which is positioned between the two casting belts is moved out of position.
