Patent CA-2111617-A1 (CA)
Inventor: THOMPSON RICHARD K
IPC: A61B19/00
Filed: 1993-12-16
Abstract: A current sensing device enables sensing the current being delivered from a source to a load at a medical implement connected to the distal end of a primary conductor connected between the source and the load in situations wherein distributed capacitance between the primary conductor and a return path to the source prevents a measurement of current at the source end of the primary conductor from being an accurate measurement of the delivered current.  The current sensing device comprises a reference conductor which is located beside and twisted together with the primary conductor along the length thereof but which terminates short of, and is not connected to, the medical implement load, and a subtractor for subtracting the current flowing through the reference conductor from the total load current flowing to the medical implement so as to offset the effect of the distributed capacitance and to thereby produce a current measurement corresponding to the delivered current.  The subtractor can comprise a current transformer through which the conductors extend in opposing relation.  An integrity detector monitors whether the reference conductor is intact.

Title: Process and Apparatus for Producing Ultrafine Explosive Particles
Inventor: MCGOWAN MICHAEL J
IPC: C06B21/00
Filed: 1991-08-27
Abstract: A method and an improved eductor apparatus for producing ultrafine particles is disclosed.  The exclusive particles, which when incorporated into a binder system, have the ability to propagate in thin sheets, and have very low impact sensitivity and very high propagation sensitivity. A stream of a solution of the explosive dissolved in a solvent is thoroughly mixed with a stream of an inert nonsolvent so as to obtain nonlaminar flow of the streams by applying pressure against the flow of the nonsolvent stream, to thereby diverge the stream as it contacts the explosive solution, and violently agitating the combined stream to rapidly precipitate the explosive particles from the solution in the form of generally spheroidal, ultrafine particles. The two streams are injected coaxially through continuous, concentric orifices of a nozzle into a mixing chamber. Preferably, the nonsolvent stream is injected centrally of the explosive solution stream. The explosive solution stream is injected downstream of and surrounds the nonsolvent solution stream for a substantial distance prior to being ejected into the mixing chamber.

Patent CA-2117990-A1 (CA)
Inventor: FREEDMAN ROBERT
IPC: G01V13/00
Filed: 1994-10-12
Abstract: A system includes a wellbore tool disposed in a wellbore and a surface apparatus disposed at a surface of the wellbore. Prior to operating the tool to take an initial measurement, the wellbore tool is first calibrated to take into account magnetic junk which is magnetically attracted to and accumulated on a magnet housing of the tool. To calibrate the tool, a new tuning frequency, called the Larmor frequency, is determined, and the tool is tuned to the new Larmor frequency before taking an initial measurement. The wellbore tool and the surface apparatus each include a processing system. Each processing system includes a memory. A first part of a tuning frequency determination software is stored in the memory of the tool, and a second part of the tuning frequency determination software is stored in the memory of the surface apparatus. To determine the tuning frequency, the processing system in the wellbore tool initiates execution of the first part of the tuning frequency determination software. Results from this first execution are transmitted uphole to the surface apparatus. The processing system in the surface apparatus then initiates execution of the second part of the tuning frequency determination software. When this second execution is complete, the new tuning frequency, known as the Larmor frequency, is determined. The wellbore tool is then tuned to the new Larmor frequency.
