Title: Low threshold cardiac pacing electrodes
Inventor: BAKER ROSS G JR
IPC: A61N1/05
Filed: 1987-03-06
Granted: 1992-07-21
Abstract: ABSTRACT    An electrode for use in cardiac pacing has a substrate composed of a material  conventionally employed for pacing electrodes,  and a surface  layer or  film of iridium oxide overlying the substrate.   For use as a stimulating cathodic electrode and a sensing electrode, the iridium oxide layer is arranged  to be  in cardiac tissue stimulating relationship when the electrode is in proper position with respect to the patient is heart.  The electrode impresses electrical stimuli on the excitable myocardial tissue to provide pacing at very low  stimulation  thresholds.    At  the  completion of  each stimulus,  the  electrode  is capable  of  abruptly  sensing, within  an  interval  less  than  100  ms  thereafter,  the electrical activity of the heart in response to the stimulus to reliably verify capture.  The surface of the electrode may be provided with recesses to which the iridium oxide layer may be confined.  An iridium oxide layer may be provided on both the cathode and the anode for efficient transduction at the electrode-electrolyte interface formed by the surface of the iridium oxide layer and the surrounding body fluid and tissue.

Patent CA-1293414-C (CA)
Title: Method and apparatus for spray coating of refractory material to refractory construction
Inventor: WATANABE SEIJI
IPC: B05D1/10
Filed: 1987-04-27
Granted: 1991-12-24
Abstract: ABSTRACT OF THE DISCLOSURE           Spray coating is performed utilizing a mixture of  refractory  material  and  a  combustionable  metal powder.   The size of the particle of the metal in the mixture is selected so that the particle size is large enough to be treated safely and is small enough to be transported by means of a gas flow.   As a carrier gas for carrying the mixture,  a non-combustionable gas or fuel gas is used.  A fuel gas and a combustion-assisting gas are discharged toward the section to be treated on the surface for directing a combustioning frame.   The refractor material with the carrier gas is discharged into the frame  established  by  the fuel  gas  and the combustion-assisting gas.  The average size of the metal particle to be used in the spray coating is limited to be greater than 50 µm.   By enlarging the particle size of the metal, combustion of the metal particle becomes difficult.  Combustion of such large particle size metal can be assisted by discharging the combustion assisting gas  together  with  the  fuel  gas.    This  compensates combustion efficiency  to be  dropped by  utilizing the larger particle size metal.

Title: Automated control of glass container manufacture
Inventor: DAVEY RICHARD G
IPC: B07C5/34
Filed: 1987-11-03
Granted: 1991-02-05
Abstract: Abstract of the Disclosure A glassware   production   system   includes   an electropneumatic individual section glass forming machine having a multiplicity of operating mechanisms for converting a gob of molten glass into a hollow glass container.  A glass forehearth feeds molten gobs at controlled temperature and weight to the forming  machine.   Electronic  controllers  individually  and selectively control parameters of operation of the multiplicity of machine mechanisms and the forehearth.  Glassware from the forming machine is inspected for manufacturing faults and for identifying each inspected container with its associated mold of origin.   The glassware inspection devices provide fault signals indicative of a plurality of differing types of faults, which are thereafter associated not only with mold or section of origin but also with fault cause.  The differing types of fault signals are thus coordinated with associated operating parameters of the forming machine and forehearth, and such operating parameters are automatically varied at the machine and forehearth controllers to correct detected faults.

Title: Back-up electrical system for lamps
Inventor: BAVARO JOSEPH P
IPC: H05B37/03
Filed: 1988-02-22
Granted: 1993-07-13
Abstract: A B S T R A C T                   A  backup  power  system  is  provided  for fluorescent lamps which energizes one of the lamps when normal  AC mains power  is  not  available.  The circuit operates with a standard fluorescent fixture which contains two or more fluorescent lamps.  When AC mains current is available, both lamps are operational so  that  the  lighting  fixture  produces  a  maximum brightness.  The AC mains current also trickle charges a  low  voltage  battery  contained  in  the  lighting fixture.   When main current  is not  available,   the battery  maintains  only  one  of  the  lamps lighted.       Consequently, although the lighting fixture produces a reduced output,  the battery life is extended.  In one embodiment both fluorescent lamps are powered directly from the AC line.  When AC power is not available, a relay disconnects  the AC  line  from both  lamps and connects one lamp to a DC/AC inverter which is powered by the internal battery.  In another embodiment,  one lamp is  powered directly  from the  AC line and the other  lamp  is  powered  by  a  DC/AC  inverter  which receives power either from a DC power supply operating off  the AC  line  or  from the  internal  low-voltage battery.   In  a  third embodiment,   during  normal operating  conditions,   both  lamps  are  powered  by separate DC/AC inverters driven from a power supply that operates off the AC line.  When the AC voltage is not  present,   the DC/AC  inverter  for  one  lamp  is powered by the internal low-voltage battery.

Abstract: ABSTRACT    A latch for oven doors and the like includes a support, and a latch assembly movable on the support between latching and unlatching positions having a handle, a latching arm and a projecting arm.  The handle is operative to move the latch arm between latching and unlatching positions.

The thermal element is being responsive to a subsequent decline in temperature to move the pawl from the second position to the first position, and the projecting arm is configured to contact the abutment in its second position 90 that the arm cannot be moved past the abutment from its unlatched position.
Patent CA-1305237-C (CA)
Inventor: PICKERING WILLIAM
IPC: H02P7/29
Filed: 1988-05-19
Granted: 1992-07-14
Abstract: Abstract Apparatus for controlling the supply of power to an electric drive motor normally controls the duty cycle of a power switching element to produce a variety of vehicle speeds.  The apparatus typically controls the rate of change of the duty cycle to provide smooth vehicle operation.  During periods of extended high speed, high load operation the apparatus bypasses the power switching element and connects the vehicle battery directly to the drive motor via a bypass contactor.  Under normal operating conditions the bypass contactor is energized after a relatively short preselected delay; however, where the vehicle is heavily loaded, such that current limiting of the power switching element exists, the apparatus interactively delays energization of the bypass contactor to allow the vehicle sufficient time to accelerate to a higher speed.  Such a control system advantageously reduces drive line shock and jerky operation of the vehicle, as well as, excessive sparking at the bypass contactor.
