Patent CA-1334129-C (CA)
Inventor: KLAUS GERHARD
IPC: C10B55/00
Filed: 1988-05-30
Granted: 1995-01-31
Abstract: The invention relates to a process and apparatus for the pyrolysis of bitumen.  The process involves spraying preheated bitumen into a generally horizontal cylindrical rotating reactor which is heated from the outside and which contains grinding bodies.  The bitumen is heated to the pyrolysis temperature and thereby forms a gaseous product and a solid pyrolyzed coke.  The solid pyrolyzed coke is removed from the reactor walls by the grinding bodies and the resulting small particles are continuously removed from the reactor through ports in the reactor wall.

Title: Electronic smoke detector
Inventor: KAPRELIAN EDWARD K
IPC: G08B17/103
Filed: 1988-08-11
Granted: 1991-11-26
Abstract: ABSTRACT OF THE DISCLOSURE    In  a  combined  obscuration  and  scattered-light smoke detector,  light from  a light  source in a smoke chamber is  reflected  from  an  image-forming  optical component onto  a first light sensor  which  senses  a reduced electrical  signal in  the  presence  of  smoke while a  second sensor,  viewing light  from the  light source at  an angle,  senses  an  increased  electrical signal in  the presence  of smoke.   The output of each receptor  is  subjected  to  a  band  pass  filter,  an amplifier  and  a  comparator;  the  resultant  signals insure early  and reliable  activation of an alarm when even a  low level  of smoke  is present  in  the  smoke detector.   A second  light source  having a wavelength different from that of the first light source produces, in the  obscuration mode,  added sensitivity  to smoke.

Granted: 1993-08-10
Abstract: INTRAVASCULAR ULTRASONIC CATHETER/PROBE AND  METHOD FOR TREATING INTRAVASCULAR BLOCKAGE                 ABSTRACT OF THE INVENTION        Apparatus and method are disclosed for treating atherosclerotic plaque and thromboses by the application of ultrasonic energy to a site of intravascular blockage.  The ultrasonic apparatus includes a solid wire probe having a bulbous tip at one end and coupled to an ultrasonic energy source at the other end, the probe being carried within a hollow catheter.  The catheter and probe are inserted into a blood vessel and are advanced to the site of a stenosis, where the probe is extended from the catheter and caused to vibrate ultrasonically, resulting in the destruction of the arterial plaque.  The ultrasonic apparatus includes a fitting for delivering a radiographic contrast solution to the probe tip by flowing the solution into the catheter, the contrast fluid being released into the blood vessel to assist in positioning the apparatus and determining the effectiveness of treatment.  A physiologic solution may also be carried to the probe tip by flowing the solution through the catheter, thereby controlling the temperature of the probe tip during the procedure.

Title: Orbital wave soldering of printed circuit boards
Inventor: SCORTA ROBERTO
IPC: H05K3/34
Filed: 1988-12-12
Granted: 1992-12-01
Abstract: ABSTRACT OF THE DISCLOSURE:            The description refers to a device and a procedure for the wavesoldering of printed circuits, in particular for the soldering of components suitable for surface mounting.  The soldering wave - or a portion of the same - is formed by molten solder flows progressing in an orbital direction.          Said flows can progress horizontally with a direction that cyclically moves between 0 and 360°, causing the removing of gas/air bubbles - in case they are trapped near a component - in any position they stagnate.  Any soldering failure due to "dry soldering" is therefore avoided.

Title: Method and apparatus for manufacturing fibre board sheets
Inventor: SOEFSTROEM CHRISTER
IPC: B27N3/00
Filed: 1988-12-15
Granted: 1993-03-30
Abstract: Abstract A method and an apparatus for manufacturing fibre board sheets according to the dry method. The fibre material is defibered in a defibrator (3), mixed with resin (7) and dried with hot gas in a tube drier (5). After the drying the drying gas is separated in a cyclone (15), whereafter the fibre material in a forming  station (16) is formed to a fibre mat, which is pressed in a pre-press (27) and finally pressed in a hot-press (28). Due to the location of the cyclone (15) above the forming station (16), the fibres are transferred directly from the drying to the forming with substantially maintained temperature, which reduces the energy demand.

Abstract: CURETTE SHARPING HONE  AND METHOD OF MAKING         ABSTRACT         A dental curette hone of a ceramic made from particulate aluminum oxide abrasive and having a curved alongate edge and a flat elongate surface.  The curved elongate edge has a radius of approximately 1/32 to about 3/32 inch.  The ceramic block is being made by forming a mixture of particulate aluminum oxide having an irregular particle shape and a selected particle size with magnesium oxide, then shaping each block by extrusion or molding.  The block is then heated to form a fused ceramic block.  The fule ceramic block is tumbled to remove irregularities from the elongate edge and flat surface after which the block is polished to form a polished surface on exposed particles of aluminum oxide.  The polished surfaces of the particles intersect irregular sides of such particles thus providing cutting edges on such particles for sharpening the curette.
