Patent CA-1215270-A (CA)

IPC: B23K3/02

Granted: 1986-12-16
Abstract: ABSTRACT           The specification describes a soldering iron in which the soldering element tip is heated by virtue of heat generated by the combustion of a gas/air mixture in close proximity to the element.  Upon initial ignition of the mixture a flame is directed onto the element which provides almost instant heat to the soldering tip.  Since the air/gas mixture is passed through a catalytic combustor which is heated by the flame, the combustor eventually begins to burn.  As the catalytic material is heated more and more of the air/gas mixture is consumed by combustion within the combustor until eventually the flame is extinguished and the soldering iron is heated solely by flameless combustion within the combustor.

Abstract: Abstract A capacitive keypad (24) is scanned in such a manner that the capacitance value (C) of an individual key in a given row is multiplied by the sum of the relative capacitance values of all the other keys in the same row by means of an amplifier (32) to generate a combined pulse. The combined pulse is then compared by a comparator (28) to a threshold voltage (Vref 3) to verify whether the individual key in question is in the closed or open position.  The verification can be made independently of keypad-to-keypad variations in the capacitances of the keys, since the combined pulse value does not depend upon the absolute capacitance value of the keys, but only upon their relative values.  Also disclosed is a method for scanning to determine the presence of multiple key closures.  This involves comparing the capacitance of an interrogated key to not only the sum of the other capacitors of its row, but also to the sum of the capacitors of the other row, and columns and a comparison of the resulting value to that generated by previous scans to detect change.

Abstract: Abstract A rack for display of articles comprises a plurality of trays for holding the articles.  Each tray comprises upper and lower courses connected at opposite ends.  At one end, an upper course communicates with the lower course by means of a gate.  The gate is controlled by the presence of objects in the lower course so that objects from the upper course are transmitted to the lower course only after the lower course is empty.  The gate includes a flag for indicating when the objects are being supplied from the upper gate.  Trays are moveable between dispensing and loading positions.  In the loading position, objects may be easily placed in the upper course so that they are passed to the lower course when the upper course becomes full.  The objects are preferably cylindrical, and the courses are arranged to allow the objects to roll along the courses to facilitate dispensing and loading.

Abstract: ABSTRACT OF THE DISCLOSURE     A power feed control system employs  an arrangement of conduits and valves for selectively directing a gas flow either through a powder feeder or through a bypass so as to quickly and precisely control the introduction of powder into and the removal of powder from the gas flow in a plasma spraying system.  The arrangement of conduits and valves includes a two-way solenoid operated valve for directing the gas flow either into a powder feeder through a main conduit or into a bypass conduit which rejoins the main conduit on the other side of the powder feeder at a powder shutoff valve and a bypass and check valve.  The bypass and check valve insures that the gas flow in the by-pass conduit flows to the output rather than upstream to the powder shutoff valve.  The powder shutoff valve includes a resilient member mounted within the bore of a housing and collapsible upon itself to close off an internal bore therein in response to the introduction of pressurized gas into a space between the housing bore and the resilient member.  Air introduced into a cannister in the powder feeder with the loading of powder into the cannister is removed by an arrangement which includes a valve for selectively coupling the inside of the cannister to a vacuum source.

Abstract: A blood pump comprises an atrium chamber defined by flexible walls and having an inlet and an outlet, a ventricle chamber defined by flexible walls and having an inlet and an outlet, a passage communicating the outlet of the atrium chamber with the inlet of the ventricle chamber, a first one-way valve in the passage adapted to permit blood flow only from the atrium chamber to the ventricle chamber, and a second one-way valve in the outlet from the ventricle chamber adapted to permit blood to flow through the outlet only out of the ventricle chamber. The chambers are movably supported in a casing having first and second openings, the atrium chamber inlet being fastened to the first opening and the ventricle chamber outlet to the second opening.

The drive device includes a drive ring surrounding and joined to the passage and having a surface engageable with the walls. of the ventricle chamber over a selected area such that the pressure of blood entering the chambers between driven strokes of the drive device controls the output of the blood pump by establishing the magnitude of the return stroke of the drive ring as a function of a pressure force acting over the area of engagement between the drive ring and the walls of the ventricle chamber.
