Patent CA-2145876-A1 (CA)
Inventor: KAISER RUSSELL E
IPC: B24B19/12
Filed: 1993-09-30
Abstract: A locking mechanism for the contouring head assembly of a belt grinding machine that employs multiple, parallel, abrasive grinding belts, and back-up shoes for pressing the belts against the surfaces on a workpiece to be ground. The locking mechanism secures the contouring head assembly to the bed of the grinding machine. The locking mechanism includes a protrusion, such as a ball, that is carried by the contouring head assembly and a pivotable arm with a socket defined near its free end. The pivotable arm is secured to a shaft that is driven by a rotary actuator, that is powered by a hydraulic motor. The socket engages the protrusion to securely support one side of the contouring feed assembly. A hydraulic cylinder forces a tapered plunger against the pivotable arm to enhance the locking action.

Inventor: KOBAYASHI HIDEO
IPC: C09D5/08
Filed: 1995-03-30
Abstract: An electromagnetic steel sheet having a corrosion-resistant electrically insulating film. The insulating film is formed by spraying and baking, on the steel sheet, a treating liquid containing an emulsion of fine resin particles, a reducing agent and an accelerator.      The emulsion of fine resin particles exhibits a weight change peak temperature of not lower than about 400°C as measured by differential thermal weight measurement conducted while raising the emulsion temperature at a constant rate of temperature rise. The emulsion also substantially resists when contacted by phosphoric acid.      The reducing agent is a phosphate ion aqueous solution containing a metal. Also disclosed is a corrosion-resistant core made from the electromagnetic steel sheet.

Title: Escape device for lowering a person from a multi-storied building
Inventor: LEFEBVRE REJEAN
IPC: A62B1/10
Filed: 1995-04-20
Abstract: An escape device is provided for lowering a person from a multi-storied building.   The escape device has a reel assembly for storing a cable, and a support assembly for suspending a loose end of the cable over an escape path leading down the building. In  a  first  embodiment,  the  reel  assembly  has  a rotatable reel for winding and unwinding the cable, a base mountable onto the building and supporting the reel, and a braking mechanism for restricting rotation of the reel at a suitable speed for a person.  The reel has a connector for retaining an end of the cable.  The support assembly has a base mountable onto the building close to the escape path, a moveable arm connected to the base and supporting a pulley for receiving the cable from the reel,  the arm being deployable and retractable between a ready position where the arm overlays the escape path and a standby position where the arm is drawn off the escape path, and   a   retraction   mechanism   for   exerting   a predetermined retraction force upon the arm to urge the arm toward the standby position, so that the arm moves from the standby position to the ready position only when the person exerts a force on the loose end of the cable.   In a second embodiment,  the reel assembly has a pair of coaxially aligned rotatable reels solid with one another for winding and unwinding respectively a pair of cables for lowering persons alternately.  A pair of support assemblies are then provided for suspending loose ends of the cables over respective escape paths leading down the building on opposite sides of the reel assembly.  The unwinding of one of said cables causes the winding of the other cable.

Inventor: DEL GIUDICE MASSIMO
IPC: G02B1/10
Filed: 1995-05-04
Abstract: The  present invention relates to a process for the treatment  of the facets of a semiconductor laser, capable of inhibiting  their degradation  during the high power operation and to the  relative laser device.  The  invention provides for a process to be carried out  in  high vacuum  condition,  capable  of  removing  contaminants  and  the products of reaction between the atmosphere and the  constituents of the semiconductor laser.          At the  same time, a process of hydrogen  diffusion  leading  to passivation  (inactivation)  of  deep  electron  energy   levels, responsible  for  various undesired  processes  of  non-radiative recombination, is carried out.          Moreover, a protective dielectric layer capable of preventing the contact  between the semiconductor surface and the atmosphere  is applied.

Title: Processing of signals for interlaced display
Inventor: MOK SIU-CHEUNG
IPC: G09G5/18
Filed: 1993-11-09
Abstract: Conversion of a computer graphics signal into an interlaced TV  video signal using conventional signal processing can give rise to considerable flicker in the resulting display where there are highly contrasting odd and even fields. With the inventive signal processing means the output for each line of the video signal is created by summing a reduced intensity version of the current field and the filtered versions of the immediately adjacent field lines. The effect of applying the filter of a preferred processing means to a single pixel signal in line n is shown in the filter characteristic of the figure, the filter comprising a low-pass filter means which derives a low frequency Fourier component of the adjacent field lines that represents their brightness but not the fine details. This enables fine details to be preserved whilst substantially reducing flicker in the display.

Title: Method of processing seismic data
Inventor: DE HOOP MAARTEN
IPC: G01V1/28
Filed: 1995-07-06
Abstract: A method is provided for processing seismic data samples obtained from seismic signals propagating in an anisotropic medium. The data samples are associated with scattering angles and azimuth at each migration dip at each image point of the medium. An inverse operator is then applied to the samples so as to provide intermediate anisotropic elastic parameter combinations for each migration dip at each point of the medium. The inverse operator comprises an inverse of a scattering function for variations in elastic parameters from a reference medium against scattering angle and migration dip. The intermediate anisotropic elastic parameter combinations are then migrated to their proper locations.
