Patent CA-2006472-C (CA)
Title: Signature handling apparatus
Inventor: BELANGER ROGER R
IPC: B65H29/12
Filed: 1989-12-21
Granted: 1995-01-10
Abstract: A signature handling apparatus includes a first conveyor which sequentially moves signatures to a discharge station.          At the discharge station, the signatures are sequentially transferred to a receiving conveyor.  A corrugator assembly is located at the discharge station to stiffen the signatures by forming corrugations which extend between leading and trailing end portions of the signatures.          Although the corrugations are only temporarily maintained in the signature, the corrugator assembly is close enough to the receiving conveyor so that a corrugation is maintained in a signature as a leading end portion of the signature moves to the receiving conveyor.  Thus, the corrugator assembly is spaced from the receiving conveyor by a distance which is less than the distance between the leading and trailing end portions of the signatures.

Title: Improved compost bin
Inventor: BARCLAY JOHN L
IPC: C05F9/02
Filed: 1990-02-06
Granted: 2001-12-04
Abstract: A compost bin, according to the present invention, comprises sidewalls and a lid which when assembled and placed on the ground, defines a closed enclosure for receiving organic material which is to be converted into compost. The sidewalls are divided into a lower section and an upper section. The lower section has a number of air entry ports for providing air to the compost material adjacent the bottom of the bin, which material is undergoing decomposition at an accelerated rate relative to organic material thereabove.      The upper section of the sidewalls are closed and cooperate with the lid to act as a barrier to the entry of air into the bin and to retain heat generated by the compost reaction as well as serving to retain moisture driven from the material during the composting process. The moisture in the air is retained in the upper section of the compost bin and will condense on the surfaces of the lid and sidewalls of the compost bin when they are cooled, such as at night, to return the moisture to the material. The compost bin can further be improved by manufacturing the bin of a black material, preferably by adding carbon black to recycled polyethylene.
Patent CA-2013071-C (CA)
Inventor: BEIERLE ROBERT T
IPC: G01H17/00
Filed: 1990-03-26
Granted: 1995-05-09
Abstract: Disclosed is an adaptive canceler (32) in which a pipelined approach is used wherein reference signals are divided  into two or more  sections having  concurrent weight adjustment.   This architecture allows the speed of adaptive  cancellation to be  increased  and/or the number of reference taps to be increased without loss of cancellation speed.  Once a continuous stream of digital data has been established  in this  architecture,  the speed of  the adaptive  processor  is  limited  only  by approximately  the  processing  time  of  the  slowest element.    The  noise  canceled  signal  may  then  be converted to the  frequency domain in a  fast Fourier transform device (34).

Title: Solvent and water/surfactant process for removal of bitumen from tar sands contaminated with clay
Inventor: GUYMON E PARK
IPC: B03B9/02
Filed: 1990-09-04
Granted: 1996-09-24
Abstract: This invention involves the separation of clay-contaminated bitumen from sand with a solvent. The bitumen is dissolved with an organic solvent such as condensate from a natural gas well. The clay is separated from the dissolved bitumen and the solvent is recovered and recycled. The sand is washed with water containing a carefully selected, nonanionic surface active agent to remove residual bitumen and solvent. Prior removal of the clay precludes it from unduly contaminating the water.

Abstract: A fibrous faced carpet includes a nonwoven fleece fabric positioned against the carpet secondary backing.  The fleece fabric is embossed to form high and low areas with the low areas extending into the secondary backing and serving to unitize the fleece fabric with the secondary backing.  A layer of pressure sensitive adhesive is on the exposed outer face of the fleece fabric for releasably securing the carpet to an underlying floor.  The low areas of the embossed fleece fabric serve for reducing the exposed surface area of the layer of adhesive that is available to contact the underlying floor.

Title: Automatic device configuration for dockable portable computers
Inventor: CANOVA FRANCIS JAMES JR
IPC: G06F13/14
Filed: 1991-12-05
Granted: 1996-06-25
Abstract: Apparatus and a method for automatically configuring communication port assignments in dockable portable computer systems wherein a portable computer unit is operable both on a stand-alone basis and attached (docked)  to a generally stationary  expansion  (docking)  unit  providing  extended connectivity and power  sourcing facilities.  The portable computer  unit  may  contain  integral  connectors  (RS232, telephone  jacks,  parallel  port  connectors,  etc.)  and internal circuit devices operating through the connectors (modems,  circuits supporting RS232 signalling,  etc.).  The docking unit may also have such connectors and associated circuits.  The  computer user may assign internal  logical communication  paths  com  x  (x  =  1,  2,  ...)  to  these connectors and their associated circuits.  When the portable unit is in a docked mode, care must be taken that duplicate paths  are  not  concurrently  active  in  the  portable  and docking units  leading  to  potentially  conflicting  signal processes in the units. The present invention provides an automatic  initialization  process whereby  the  system  is automatically configured to operate without path conflicts when it is docked and to make full use of all internal paths in the portable unit when the base portable unit is not docked; all transparent to system users.

Title: Rinse aid dispenser
Inventor: COOPER RANDALL L
IPC: A47L15/44
Filed: 1992-05-29
Granted: 1996-10-01
Abstract: An adjustable rinse additive dispenser is provided for a dishwasher having a washing compartment and a door pivotal between a horizontal open position and a vertical closed position.  The dispenser includes a rinse additive reservoir mounted on the door.  A conduit provides a fill opening for adding rinse additive to the reservoir.  A knob assembly includes a shaft extending into the conduit so as to substantially seal the opposite ends of the conduit, and defines an annular chamber within the conduit.  A trough is provided in the reservoir for holding a fixed quantity of rinse additive.  A passageway provides communication between the trough and the annular chamber, and is normally closed by a plunger assembly.  During the last rinse cycle of the dishwasher, the plunger assembly is moved to an open position so as to allow rinse additive to flow from the trough into the annular chamber.  A leak path is provided in the knob assembly so as to allow a selective amount of rinse additive to flow from the annular chamber into the washing compartment of the dishwasher.  The quantity of additive dispensed from the annular chamber can be varied by turning the knob assembly such that the angular position of the leak path is raised or lowered.

Title: Distance marker within a golf course fairway
Inventor: BAILEY JOHN M
IPC: A63B57/30
Filed: 1992-09-28
Granted: 1995-10-10
Abstract: A visual distance marker for a golf course fairway which provides viewable indicia of distance along the fairway such as from a tee. The device includes an elongated resilient marker strip having an enlarged anchor portion at its lower end. When the anchor portion is embedded or buried in the ground the marker strip is supported in an upright orientation extending above the ground. The marker strip is thin and sufficiently resilient in one plane so as to be deflected and bent over against the ground as a reel-type lawn mower approaches and passes thereover, thus eliminating the need for removing and replacing the device during normal mowing operations.
