Abstract: An  implantable  atrial  defibrillator  and  method provides cardioverting electrical energy to the atria of a human  heart  in  need  of  cardioversion.    The  atrial defibrillator includes a first detector for detecting R waves of the heart, a second detector for detecting T waves of the heart, and a third detector for detecting atrial activity of the heart.  An atrial fibrillation detector is responsive to the third detector for determining when the atria of the heart are  in need of cardioversion.   A cardioverting stage applies the cardioverting electrical energy to the atria of the heart when the atria of the heart are  in need of cardioversion,  after the  second detector detects a T wave, and in timed relation to an R wave detected by the first detector after the detected T wave is completed.   The atrial defibrillator includes a timer for timing a predetermined delay time after the T wave is detected, which delay time must be completed before the atria are cardioverted in timed relation to a detected R wave to assure that the detected T wave is completed.

Abstract: The present invention relates to the detection of errors in seismic data and in particular to apparatus for detecting errors in frames of seismic data that can be presented as images.  Due to the techniques used for collecting seismic data, an image produced to represent that data will typically be expected to exhibit an inherent symmetry about an axis. The apparatus of the present invention comprises a storage device for storing a frame of seismic data which can be presented as an image, a selection device for selecting an axis within the image as the axis of symmetry, and a divider for dividing the data about the axis of symmetry to create first and second sets of data.  Further it includes a comparison means for comparing the sets of data according to preselected matching criteria to determine,  based on the degree of matching, whether the extent of mismatch in the frame of data is within a predetermined tolerance.

Title: Lithographic printing plates with photoreactive polymeric binders
Inventor: FITZGERALD MAURICE J
IPC: G03F7/027
Filed: 1994-10-27
Granted: 2007-09-25
Abstract: A photoreactive binder that may be used to enhance photospeed in either conventional plates or on-press developable lithographic printing plates. Briefly, a polymer of m-isopropenyl-.alpha., .alpha.-dimethylbenzyl isocyana te is derivatized for vinyl group reactivity by reacting the isocyanate groups thereof with hydroxyalkyl acrylate. The resulting photopolymeric binder provides significantly higher photospeed than the non-reactive binder currently utilized in the production of conventional printing plates. The resulting lithographic printing plate also shows better durability (as manifested by longer run-length) and is more easily developed by the microencapsulated developers utilized in the present invention. As to the preparation of the photoreactive binders, the application discloses a method of copolymerizing m-isopropenyl-.alpha., .alpha.- dimethylbenzyl isocyanate (m- TMI) through complexation with an electron-deficient monomer such as maleic anhdride to accelerate free radical copolymerization with other monomers, an d thus, provides greater monomer-to-polymer conversion. Use of the resulting product in the photoresist of a lithographic printing plate improves its adhesion to an underlying substrate.

Abstract: An ultrasonic rail flaw detection system and technique are described for the detection of flaws in the sides of rail heads. An ultrasonic transducer (20) is oriented, sized, and located so as to produce an ultrasonic beam (50) within the rail head (48) whereby at least a portion of the beam will intersect a lower side corner independent of the curvature of the rail head running surface and the amount of head wear. The presence of premature reflections or the absence of reflections can be used to detect flaws such as vertical fractures in the rail head. The side-looker is so oriented as to produce a beam in the rail head that lies within 45 degrees to 75 degrees of the normal to the rail surface, and can be located such that its beam and the beams from other ultrasonic transducers do not interfere with each other.
Patent CA-2155917-C (CA)
Inventor: SCHULTZ ROGER L
IPC: E21B47/06
Filed: 1995-08-11
Granted: 1999-09-28
Abstract: Early evaluation testing of a subsurface formation is provided by monitoring pressure fall-off in the formation. This is accomplished by providing a column of fluid in the well having an overbalanced, hydrostatic pressure at the subsurface formation greater than a natural formation pressure of the subsurface formation. A testing string is run into the well, and the testing string includes a packer, a pressure monitor and a closure tool arranged to close a bore of the testing string. The formation is shut in by setting the packer and closing the bore of the testing string with the closure tool and thereby initially trapping the overbalanced hydrostatic pressure of the column of fluid in the well below the packer. Then the pressure in the well below the packer is monitored as it falls off toward the natural formation pressure. This data can be extrapolated to estimate the natural formation pressure based upon a relatively short actual test interval on the order of ten to fifteen minutes.
