Title: Minature steroid eluting pacing lead electrode
Inventor: STOKES KENNETH B
IPC: A61N1/05
Filed: 1991-06-11
Abstract: A small diameter, unipolar or bipolar, atrial or ventricular transvenous or epimyocardial pacing lead with a porous, platinized, steroid eluting cathode electrode exhibiting an effective surface area in the range of 0.1 to 4.0 mm2, preferably 0.6 to 3.0 mm2, provides low stimulation thresholds in the range of 0.5 volts, 0.5 milliseconds, very high pacing impedance (800 to 2,000 .OMEGA.), relatively low polarization, good to excellent sensing, and adequately low source impedance. The high pacing impedance prolongs the longevity of pacing pulse generators and allows for the miniaturization of their components. The low thresholds allow large safety factors at low applied voltages, which also contribute to increased battery longevity.

Patent CA-2089856-A1 (CA)
Inventor: LUPYNEC MICHAEL
IPC: E05F1/10
Filed: 1993-02-18
Abstract: ABSTRACT         A cabinet is disclosed for storing planar sheets such as blueprints having a two stage door latch mechanism.       The latch permits the cabinet door to be opened to a sort position wherein holding hooks supporting the hanging objects are in a closed position so that the sheets may be sorted through.  The door can then be opened to a retrieval position corresponding to the holding hooks in the open position so that sheets may be added to or removed from the cabinet.  In one form of the latch a slotted arm is pivotally attached to the door at one end and coupled to the back wall by a spring.          A cam having an open slot is pivotally mounted to the arm at one end and while the other end is provided with a ball catch for locking the cam to the arm.  A switch is constrained to move in the slots.  The end of the cam slot spaced from the pivotal connection is displaced from the cam slot longitudinal axis so that when the switch contacts that end of the cam slot, the cam is pivoted downwards thereby disengaging the ball catch from the arm.  The switch abuts the end of the cam slot thereby stopping the arm and holding the door in the sort position.    Moving  the  door  backward  a  short  distance disengages the switch from the cam whereby the latter pivots downwards causing the switch to exit the cam slot whereupon the door opens to the retrieval position.   As the door is returned to the closed position a ramp re-engages the cam in its original position.

Patent CA-2102203-A1 (CA)
Title: Catalytic cracking process and apparatus
Inventor: SERRAND WILLIBALD
IPC: C10G11/18
Filed: 1992-04-24
Abstract: A catalytic cracking process and apparatus are described wherein particles of cracking catalyst circulate continuously between a reaction zone and a regeneration zone. Hot regenerated catalyst from the regeneration zone contacts hydrocarbon feed in the reaction zone to produce cracked hydrocarbon products and spent catalyst. The spent catalyst is recovered and subjected to stripping in a stripping zone to remove strippable material therefrom. The stripped spent catalyst is circulated to the regeneration zone for oxidative exothermic regeneration. Some hot regenerated catalyst is passed directly from the regenerator to the stripping zone via a conduit provided for this purpose. Another hydrocarbon stream is passed into contact with the hot regenerated catalyst in this conduit. The said other hydrocarbon stream is converted to products of enhanced value (e.g., olefins) during contact with catalyst in the conduit, and the said products are recovered. The heat for the conversion is abstracted from the catalyst particles passing via the pipe to the stripping zone. The hot catalyst particles entering the stripping zone from the pipe increase the temperature in the stripping zone, thereby improving the stripping in the stripping zone.

Filed: 1994-03-29
Abstract: A gamma radiation dosimeter comprises a polyester film substrate 10, of which a central circular region 12 is coated with a gamma-radiation sensitive layer 14 which is covered by an overlayer 16. The radiation-sensitive layer 14 is formed from styrene-acrylonitrile copolymer and contains 1-bromoadamantane and a leuco dye. The overlayer 16 is formed from an acrylic resin binder containing a UV-absorber. The central region 12 is surround by an annular region 18 which is divided into six equally-sized sections 18a.....18f. Each section 18a.....18f is printed in a colour which corresponds to the colour developed in the central region 14 when it has been exposed to successive increasing amounts of gamma radiation.      After exposure of the device, the amount of radiation to which the device has been exposed can be determined by comparing the colour generated in the region 14 with the colours of the sections 18a.....18f. The colour of the section most closely corresponding to that of the central region indicates the dose of gamma radiation which the device, and any other object similarly exposed, has received.
