Abstract: LOCKING FASTENER ASSEMBLY FOR THREADED JOINT     ABSTRACT OF THE DISCLOSURE         A locking fastener assembly for axle bearings and the like is free spinning during tightening and removal and is positively held against rotation after installation. The assembly is engageable with an axially slotted male threaded member and includes a nut with female threads and a flange end.

Abstract: PWM SYSTEM FOR ECM MOTOR                     ABSTRACT OF THE DISCLOSURE       A pulse width modulation control system for an electronically commutated motor (ECM) adapted to be energized from a DC power source includes a power switching system coupled in circuit with each winding stage terminal of the ECM for selectively coupling each terminal to the DC power source for applying a DC voltage to selected ones of the winding stages of the ECM in a preselected sequence to effect energization of the ECM.  m e control system includes signal processing circuitry for generating switching signals for identifying selected power switching devices for energization in order to connect each terminal of the ECM to the power source in the preselected sequence.  A Pulse width modulation (PWM) circuit generates PWM enable signals for energizing the selected power switching devices and includes a clock for generating periodic clock signals defining sequential clock intervals of predetermined duration.  A logic circuit is coupled to the PWM circuit for limiting the cycling of the PWM enable signal to once per clock interval.  In the disclosed method, a pulse width modulation enable signal is summed with control signals to each of the power switching devices for energizing the ECM winding states in the preselected sequence.  The PWM enable signal is terminated when current in the winding stages reaches a predetermined value and the PWM enable signal is then inhibited for at least a time duration of a one of the clock signals if the termination has occurred within a predetermined time interval of a one of the clock signals. If current in a winding stage has not reached the predetermined value at the time that a clock signal is generated, the PWM enable signal is terminated for at least a predetermined minimum time period. Additionally, the PWM enable signal may be inhibited for another predetermined minimum time period during each PWM cycle.

Title: Catheter for endocardial biopsy, which can also be used for identifying the point of origin of ventricular arrhythmia
Inventor: SALERNO JORGE A
IPC: A61B5/296
Filed: 1988-11-16
Granted: 1993-03-02
Abstract: ABSTRACT OF THE DISCLOSURE            A catheter for endocardial biopsy comprises a distal portion provided with biopsy forceps including two jaws which are movable relative to each other between an open position and a closed position, and means which are operable from the proximal end of the catheter for causing the movement of the jaws.  The two jaws of the forceps are of electrically conductive material,  are insulated   from   each   other,   and   are  connected respectively to two terminals situated at the proximal end of the catheter so that, when the jaws are in their open  position,  they  can  be  used as  electrodes  for identifying  the  point  of  origin  of  a  ventricular arrhythmia.   It  is  thus  possible  to  carry  out  an endocardial biopsy in apparently normal patients with ventricular arrhythmia, tissue samples being taken both in  correspondence  with  the  zone  of  origin  of  the arrhythmia  and  in  correspondence  with  other  zones, immediately after the identification of the zone of origin.   In a variant, one of the two electrodes is constituted by the two jaws and the other by a ring carried  by  the  body  of  the  catheter  and  arranged coaxially with the catheter.

Abstract: ABSTRACT                   "ELECTRIC ARC REACTOR" An electric arc reactor having a substantially straight feed material passage extending through both the anode and the cathode.  Gas is fed into the gap between the two electrodes so as to swirl about the axis of the feed passage and thereby confine the lateral extent of the arc and also confine the location  at  which  the  upstream  arc  root  attaches  to  the upstream electrode.  An enlargement of the passage in the gap end of  the upstream electrode provides  an internal sloping root  attachment  surface.   A  similar  enlargement  may  be provided in the downstream electrode, but spaced from the gap, if the downstream electrode forms the cathode.  Gas flow in a direction towards the upstream end of the feed passage is used to control the location at which an arc root attaches to the sloping surface of a passage enlargement.  Magnetic means is provided to induce  rotation of  the  arc  such  as  to  form a hollow arc column which is coaxial with the feed passage and through which feed material can pass.
