Patent CA-2009411-A1 (CA)
Inventor: KOLK STEPHEN B
IPC: B27M3/00
Filed: 1990-02-06
Abstract: MONOLITHIC FINISHING PROCESS AND MACHINE      FOR FURNITURE PARTS AND THE LIKE  ABSTRACT OF THE DISCLOSURE         A process and machine are provided to manufacture furniture parts and the like with a unique, durable, low gloss finish which has a soft, satin feel, and imparts a monolithic appearance to the part.  A blank cut from a suitable substrate material is grooved about its marginal edge to a depth near the opposite surface of the blank.  A liquid edge protection material is poured into the groove and fully cured.  The blank is then cut through at the filled groove to create a decorative protective strip about the marginal edge of the blank.  The formed blank is next coated with a selected paint or base material.  After the base coat is cured, a layer of UV curable, protective material is applied to the painted surfaces of the blank.          The UV coated blank is then translated through a multi-stage, continuous feed, ultraviolet processor to selectively and sequentially cure the protective coat.  Powered rollers arranged in spaced apart groups convey the parts through the processor.  UV light sources are located above and below the rollers, vertically in line with the spaces between adjacent roller groups, and have selectively oriented reflectors which contemporaneously and uniformly radiate all of the W coated surfaces of the blank to form a mar-resistant, low gloss protective coat, which together with the base coat, imparts a soft feel, and monolithic appearance to the finished part.

Title: Voltage-to-frequency squared circuit
Inventor: ZYLSTRA HENRY J
IPC: G01R19/252
Filed: 1990-03-09
Abstract: ABSTRACT OF THE DISCLOSURE    A voltage-to-frequency converter is provided for generating a frequency which is proportional to the square of the input voltage provided to the converter.  Since the input voltage is correlative to current flowing in a conductor, the output frequency exhibits a proportionality similar to the relationship between the temperature of the conductor and the current flowing in it.  The arrangement includes two charging circuits which receive the input voltage and are alternately charged as a function of the input voltage.  While the first charging circuit charges to a predetermined voltage, the second charging circuit discharges.  Upon exceeding the predetermined voltage, the output of a flip flop is set to discharge the first charging circuit, and to charge the second charging circuit.  When the second charging circuit charges to a predetermined voltage, the output of the flip flop is reset, so that the first charging circuit charges again.  As the input voltage rises, the charging time for each circuit decreases, thus causing the output of the flip flop to switch at a higher frequency.  In effect, the frequency of the output of the flip flop changes at a rate proportional to the square of the input voltage.

Title: Process for making carboxylic acid esters using a crosslinked acrylic resin as the catalyst
Inventor: RABON JAMES A JR
IPC: B01J31/08
Filed: 1990-05-28
Abstract: ABSTRACT         The production of esters via the reaction of an epoxide with a carboxylic acid has been shown to give improved activity when a strong base macroporous anion exchange resin having an acrylic backbone is used in place of a styrene-divinylbenzene based anion exchange resin having an equivalent exchange capacity.  Excellent results are obtained when acrylic acid and propylene oxide are reacted together in the presence of strong base macroporous anion exchange resins which have an acrylic backbone.   35,705-F

Title: Thermal protection circuit for an integrated circuit subscriber line interface
Inventor: PATEL LALIT O
IPC: H04M3/18
Filed: 1990-11-01
Abstract: A THERMAL PROTECTION CIRCUIT FOR AN INTEGRATED CIRCUIT       SUBSCRIBER LINE INTERFACE                         ABSTRACT A thermal protection circuit for an integrated circuit subscriber line interface is disclosed. The thermal protection circuit monitors the temperature of the integrated circuit and develops an output voltage signal that shuts-down the integrated circuit when a specific temperature is exceeded.  The thermal protection circuit includes first and second current networks arranged to each develop first and a second currents respectively, of substantially the same value.  The second current develops a reference voltage which is applied to an output transistor.  When the base-emitter junction voltage of the output transistor is less than or equal to the reference voltage, the transistor begins to operate.  This increases the current flowing through the first current network which is replicated in the second current network.  The increased current flowing in the second current network increases the reference voltage, thereby, fully operating the output transistor and developinq the output voltage signal.

Abstract: (SS 21, 31, 24 AND 142) ABSTRACT   In a structure for temporary habitation on the ice, it is generally known they are constructed of wood or canvas-like material.  In a a canvas type structure for use on the ice, the difficulty has always been keeping the structure stable and secure on the ice.  In this invention, the collapsible legs of the structure are prevented from slipping on the ice by placing their bases in holes drilled in blocks.  These blocks have a layer base area than the legs and therefore are less susceptible to sinking in the ice.  The blocks have an anti-slip base to provide good adherence to the ice. In addition, an anchoring system comprised of tie-downs frozen in the ice at one end and running diagonally to the peak ends of the structure and secured, provide long term stability for the structure.

Title: Method of electrostatically spray-coating a workpiece with paint
Inventor: KUBOTA TOSHIO
IPC: B05B15/55
Filed: 1992-02-13
Abstract: A method of electrostatically spray-coating a workpiece with electrically-conductive paint subjected to a voltage using a spray gun, the spray gun having a rotatable atomizing head attached to a rotator for rotating the atomizing head.  A paint supply line supplies paint to the atomizing head and a cleaning line supplies cleaning liquid and air, where the air is under a pressure, to the atomizing head.  The rotator has a path for accommodating the paint supply line and the cleaning line therein, that path being formed in a cylindrical shape along a rotative axis of the rotator.  The cleaning line is disposed coaxially in the path with an end opening thereof disposed in the atomizing head.  The paint supply line is disposed coaxially within the cleaning line and has a nozzle tip thereof projecting frontward from the end opening of the cleaning line into the center of the atomizing head, preventing liquid communication between it and the cleaning line.  The method comprises the steps of: electrostatically spray-coating the workpiece with the paint; supplying the cleaning liquid to the atomizing head via the cleaning line to wash the atomizing head after spray-coating; supplying the air to the cleaning line after washing the atomizing head, to discharge the cleaning liquid remaining in the cleaning line through the atomizing head, at a delivery rate within a rate of spraying the paint during the spraycoating; and drying the cleaning line before spray-coating a next workpiece, to prevent voltage leakage, with air under pressure higher than an air pressure used for discharging the remaining cleaning liquid.
