Patent CA-2117803-A1 (CA)
Title: Active cancellation of noise or vibrations
Inventor: CHAIT JAIME
IPC: G10K11/178
Filed: 1993-04-09
Abstract: An active noise cancellation system processes a residual signal (r), generated by the interaction of a noise signal (p) and a cancelling signal (s), in the frequency domain so as to produce a new cancelling signal. A Fourier transformer (5, 8) operating in accordance with a moving discrete Fourier transform algorithm is used to produce a frequency domain representation of the residual signal.
Patent CA-2118856-A1 (CA)
Inventor: SHARPE ROBERT C
IPC: C25D3/22
Filed: 1994-03-11
Abstract: Protective coatings for metallic substrates, such as fasteners like lug nuts, bolts and anti-theft wheel locking devices for motor vehicles have enhanced protection from salt spray and other highly corrosive environmental elements by plating their base metal substrates with an electroplated sacrificial metal, particularly zinc or zinc-nickel alloy, a white corrosion inhibiting precoating and at least one additional coating applied from a curable aqueous   one-step   surface   phosphatization   corrosion resistant coating composition comprising mainly an acrylic copolymer,  a  non-leachable  chromium  based corrosion inhibitor,  a  zinc salt and   phosphoric acid.   Coated articles when fully cured possess anti-corrosion properties which are potentiated over one-step surface phosphatization coating compositions used on metal substrates alone or on non-electroplated metal coated substrates, so as to extend the useful life of the coated article.

Inventor: HOHLA KRISTIAN
IPC: A61F9/008
Filed: 1993-09-30
Abstract: An apparatus and method for controlling an apparatus for removing tissue from the eye performs various types of corrections using a relatively large beam, but oscillating, or dithering, that being to prevent reinforcing ridges from being formed during the tissue removal process. Further, various types of correction, such as hyperopia and astigmatism correction, are performed using a large beam that is scanned over the area to be ablated using overlapping shots. Further, the epithelium in the area to be treated is removed using an infrared fluorescent dye to dye the epithelium, and then observing the fluorescent patterns from the epithelium area to be removed. Once a certain area is no longer fluorescent after laser shots, smaller shots are then applied, selectively removing the epithelium from the remaining regions. Again, the fluorescence patterns are observed, and the process is repeated until no epithelium remains. At this point, all of the epithelium is removed, and further a map is created of the initial epithelial thickness at each point in the area from which the epithelium was removed.

Abstract: A vehicle steering system (10, 190, 290) includes inner and outer coaxial valve members (40, 42) which are rotatable relative to each other to port fluid to a vehicle power steering motor (30).  A plurality of rocker arms (122, 302) are pivotally connected to the inner valve member (40).  Each rocker arm (122, 302) is pivotal relative to the inner valve member (40).  Each rocker arm (122, 302) engages a recess (132) in the outer valve member (42).  Upon relative rotation between the inner and outer valve members (40, 42), the rocker arms (122, 302) pivot relative to the inner valve member (40).  Force is applied to each of the rocker arms (122, 302) to resist pivoting of the rocker arms (122, 302) and relative rotation between the inner and outer valve members (40, 42).  In one embodiment, a plurality of pistons (222) are disposed in chambers (220) formed in the outer valve member (42). The pistons (222) are exposed to a fluid pressure which varies as a function of vehicle speed.  The pistons (222) are effective to vary the force applied against the rocker arms (122) and the resistance to relative rotation between the valve members (40, 42) as a function of vehicle speed.

IPC: B60C23/02
Filed: 1993-06-16
Abstract: An arrangement for indicating vehicle tire pressure comprises a transmitter unit (6) which is connected to a pressure monitor (20) that communicates with the air in the tire and is constructed to generate electrically an acoustic signal when the tire pressure falls beneath a given pressure level. Mounted on the vehicle is a receiver unit (3) which detects the acoustic signals, and an indicating device (4) which indicates air leakage. The acoustic signal comprises a first signal of a first frequency and a second signal of a second frequency, this second signal being produced after a given time interval. The receiver unit on the vehicle will not indicate an air leakage until the two signals have been received at the correct frequencies and at the correct time intervals.  The transmitter unit (6) is attached to the wheel rim and connected to the wheel air valve.

Abstract: A shelving support system is disclosed comprising a series of spaced vertical columnar supports (300) of steel channel having a series of cutouts (320) formed at regularly-spaced intervals in the flanges (308) thereof. Each cutout (320) defines an upper tip (323), a lower lip (235) and a rear horizontal shoulder (342).     Linear extrusions (324a and 324b) of suitable aluminium or plastics material which define shelf-slots (326) are fitted into cutouts (320) so as to be horizontally located between the backs of upper and lower lips (323 and 325) and the rear periphery (344), and, so as to be located vertically by the underside of a shoulder (342) formed on flange (308) at the rear of the cutout and a land (362) and/or the top of the lower lip (325) at or near the lower front of the cutout. Each extrusion (324) includes a curved, forwardly-facing, hook-like thumb-strip formed along its upper wall which hooks behind upper lip (323) when the extrusion is in place within the cutout (320). The extrusion (324) being fitted in place by tilting it down and to the rear until thumb-strip (326) passes under lip (323) and then swinging the front of extrusion (324) down to bring its back wall (334) into contact with rear face (344) of cutout (320).

Abstract: ABSTRACT    A label applicator for applying a label to the top surface of an object moving along a path adjacent to the applicator.  The applicator is comprised of a label printer mounted for vertical adjustment on support structure attached to a moveable frame.          The printer has a label feed position and is adjusted vertically on the support to set the label feed position to an expected median article height.  A label transport assembly, attached to the  frame,  receives  and retains  the  label  and  then moves vertically and laterally from a home position, above the label feed position, to an article intercept position, where it applies the label to the moving article.  The controller learns the home position and positions the label transport assembly at the home position to pick up labels. The label printer,  the  label transport assembly, and the moveable frame are located along side the object path such that when the label transport assembly is in the home position, the object path is vertically unobstructed.
