Patent CA-2226821-A1 (CA)
Title: Vsb symbol sync recovery system
Inventor: MUTZABAUGH DENNIS M
IPC: H04N21/438
Filed: 1998-01-13
Abstract: A symbol sync acquisition circuit for a digital VSB signal finds sync pattern correlations in the incoming signal.          Initially both positive and negative sync pattern correlations are accorded equal weight, with non sync pattern correlations being accorded a negative weight.  Values are accumulated in a segment integrator and stored in a FIFO having a location for each symbol position in a segment.  A comparator initially produces an output when sync pattern correlations are found that add to a given value.  After a relatively small number of correlations, as tabulated in a confidence counter, a VCO is enabled to change its frequency under control of error pulses based upon the symbol sync.  After a greater number of sync pattern correlations, the symbol position in the segment is fixed, sliding to a new symbol location in the FIFO is precluded, the signal polarity is determined and changed, if necessary, and a higher threshold is established for the comparator.  The confidence counter continues to build after lock is attained.          Should confidence be lost, the system resets and acquisition is started from the beginning.

Title: Sizing apparatus
Inventor: WALLACE ALLAN KENNETH
IPC: B29C48/90
Filed: 1996-09-16
Abstract: A sizing sleeve for controlling the diameter of plastic tube includes pressurised sizing sleeve portions (10) in which fluid is injected under pressure about the tube circumference to form a lubricating layer.  Drainage zones (12) axially separate and isolate adjacent pressurised portions to allow independent temperature and pressure control. Each pressurised portion has flow stabilizing means (28) reducing variations in flow responsive to changes in the lubricating layer pressure. The stabilising means may comprise a high pressure fluid source and high pressure drop constriction means comprising fine apertures (56), which may be formed as grooves milled into end surface of abutting sizing sleeve segments (30).
Patent CA-2233032-A1 (CA)
Inventor: PHILLIPS PAUL
IPC: F16K31/18
Filed: 1998-03-25
Abstract: An above-ground tank auto-limiter is provided for preventing the overflow of fluid in storage tanks. The auto-limiter includes a valve assembly insertible downward through the top of a fill pipe of the fuel storage tank.  The valve assembly has a cylindrical valve housing providing a fluid flow passage directing fuel downward into the storage tank under pressure.  A hollow cylindrical float is provided in the valve assembly and is coaxially mounted along the outside surface of the valve housing leading into the storage tank.  The float moves vertically to slide freely along the lower portion of the valve housing with the fluctuation of the fuel level within the tank.  A series of linkage assemblies communicate the cylindrical float to valve doors.  The valve doors prevent any fluid flow from passing through the fluid flow passageway when the doors are in the closed position.  Bleed valves disposed in the valve assembly above the valve doors function independently from the linkage assemblies and valve doors to allow a certain amount of excess fuel that is captured within the valve housing when the fluid flow passageway is closed to bleed into the storage tank when pressure in the valve assembly is released.                                . .

Title: Corrugated tubing fitting
Inventor: ALBINO MARK
IPC: F16L33/26
Filed: 1997-07-18
Abstract: A fitting (10) for use with corrugated steel tubing (20). The fitting (10) includes a body (12) having a locating sleeve (18). The locating sleeve (18) aligns the central axis of the body (12) with the central axis of the tubing (20). Split ring washers (16) are retained on the tubing (20) by a nut (14) which is tightened on a threaded end of the body (12). As the nut (14) is tightened, a taper formed on the body (12) flares the tubing (20). The flared tubing (22) is compressed between the taper (122) on the body (12) and the beveled section (162) of the split ring washer (16).

Title: Banknote centering device for a validator
Inventor: ONIPCHENKO ALEXANDER
IPC: B65H9/10
Filed: 1998-04-24
Abstract: A banknote centering device uses a clutch arrangement to limit inward movement of side engaging plates used to center a banknote. The clutch also allows a fixed cycle motor to be used for both inward and outward movement of the side engaging numbers. The resistance of the banknote to buckling in the slot is sufficient to cause the clutch to slip. The device is rugged, easy to produce, and has proven very reliable.

Inventor: PAYNE REGINALD K
IPC: E05F15/00
Filed: 1998-06-23
Abstract: A door obstruction detector employs an optical device, such as a segmented Fresnel lens, and a PIR sensor attached to a moving door, so that the optical device causes an image of an object, in a detection zone, to move across a sensing region of the PIR sensor when the door moves.   When the object is sensed in the detection zone, a drive signal is generated   for   controlling  movement   of   the   door. Thermistors can be used to compensate for variation in ambient temperature to adjust detection sensitivity.
Patent CA-2242112-A1 (CA)
Inventor: BROWN ROBERT JOHN
IPC: H01R13/622
Filed: 1998-07-02
Abstract: A conventional connector has a coupling nut rotatable on a body and lockable by means of a locking ring mounted on the nut. When slid axially to its locking position, the locking ring engages splines on both the nut and the body to prevent relative rotation. A circular spring carried in a groove on the nut engages on the inner surface of the locking ring to resist unlocking of the locking ring. In the present invention, the spring engages a vertical wall on the locking ring so that the locking ring cannot be unlocked by force exerted on the locking ring alone. The connector has a release ring which can be pushed axially into the locking ring so that a ramp surface on the release ring pushes the spring in arid allows the locking ring to be slid back.

Title: Piezoelectric transformer
Inventor: LE LETTY RONAN
IPC: H01L41/107
Filed: 1998-08-12
Abstract: The transformer (1) includes a body (2) made of piezoelectric material having an outer lateral surface (E) in the shape of a circular cylinder. Primary electrodes (5, 7, 10, 12, 17, 19, 22, 24) are arranged on the body (2) so that, when the primary voltage (Up) which is applied thereto has a determined frequency (fr), the outer lateral surface (E) alternately takes the shape of a first and a second elliptical cylinder, the major axes of these latter being perpendicular to each other and perpendicular to the axis (A) of the circular cylinder. This vibration mode of the body (2) has a lower fundamental resonance frequency than that of the vibration mode of known transformer bodies having the same space requirement. The transformer (1) is thus well suited to being used in devices where the available space is limited for providing a relatively high AC voltage but having a relatively low frequency.
