Abstract: The invention concerns a method of and apparatus for harvesting crops. One method involves harvesting from non-adjacent areas of land on which the crop is grown. The method comprises notionally dividing the areas of land into at least two groupings and for each region establishing a site for a cleaning mill for graff, a mixture of chaff, weed seeds and grain, harvested from said land in said region by a mobile graff harvester, cleaning graff harvested from one of said notional regions in a mobile cleaning mill provided at the site established for that region, subsequently moving said mobile cleaning mill to a site established for another of said regions, and cleaning gram harvested by a mobile graff harvester from land in said other region in said mobile cleaning mill. The invention also relates to a mobile, self powered cleaning mill and a method of rethreshing clusters of grain and chaff within a cleaning mill.

Patent CA-2390214-A1 (CA)
Title: Dialyzer
Inventor: KUYKENDALL STEPHEN
IPC: A61M1/18
Filed: 2002-07-02
Abstract: A dialyzer design that includes a potting material encasing a microfiber bundle in each end of a cylindrical body. The potting material is set by spinning the dialyzer in a centrifuge to force the potting material to the ends of the dialyzer interior chamber, where it sets with a non- planar surface. Dialysate fluid distribution rings define a space between the dialyzer interior chamber and dialyzer inlet and outlet ports, and laterally support the microfiber bundle against the dialysate fluid flow pressure. The dialysate fluid distribution ring circumferential edge substantially conforms to the non-planar potting material surface, to ensure that the lateral support to the microfiber bundle is constant, thereby lessening distortion, rupturing and obstruction of the microfibers.

Title: Welding apparatus and method
Inventor: CORDIER BERNARD J
IPC: B23K23/00
Filed: 2002-07-03
Abstract: An exothermic welding system uses compressible layers of disposable refractory batting (86,87,88) or gaskets to form a weld chamber for parts (84,85) to be welded. The parts (84,85) to be welded are layered with the batting (86,87,88) between a base (49) and a crucible platen (66) supported by a clamping fixture (30). The layered batting (86,87,88) is provided with the holes (89) intersecting the parts (84,85) to be welded. The holes (89) form the weld chamber. The crucible platen (66) is provided with a chamber (91) for the exothermic material which when ignited forms molten metal which flows through a tap hole into the weld chamber. When the weld is made, the fixture is opened (30) and the batting (86,87,88) is discarded. The invention concerns also a method of forming the welded connection by compressing the layered batting (86,87,88) and the parts (84,85) to be welded to form the disposable weld chamber enabling a wide variety of connections not requiring a large inventory of special refractory mold parts. <IMAGE>

Title: Hood latch with self-retracting secondary latch release arm
Inventor: TOMASZEWSKI KRIS
IPC: E05B65/19
Filed: 2001-01-15
Abstract: A latch assembly (10) has a housing having a mouth. A ratchet (12) is pivotally mounted to the housing and is mov-able to cooperate with the mouth to pivot between an open condition, a primary closed condition and a secondary closed condition for receiving, engaging and cinching a keeper of a striker. The ratchet (12) is biased to the open condition. A pivotally mounted pawl (40) is biased into engagement with the ratchet for releasably retaining the ratchet in the primary closed condition. A secondary release arm (20) is mounted to rotate about a first axis and a second axis.  the secondary release arm (20) is rotatable about the first axis between a retracted position and an extended position, and is rotatable out the second axis between an engaging position and a disengaging position. The secondary release arm (20) is biased to the retracted position and biased to the engaging position. The secondary release arm (20) interengages with the ratchet (12) for coupled movement therewith from the primary closed condition to the secondary closed condition effecting movement of the secondary release arm (20) from the retracted position to the extended position upon the pawl (40) being rotated to disengage from the ratchet (12).  Upon moving the secondary release arm (20) from the engaging position to the disengaging position, the secondary release arm (20) disengages from the ratchet (12) for independent movement enabling the ratchet (12) to rotate from the secondary closed condition to the open condition and back to the primary closed condition. The secondary release arm (20) also rotates from the extended position to the retracted position.

Title: Current control of a power supply for an ionizer
Inventor: JACOBS MICHAEL A
IPC: H05F3/04
Filed: 2002-08-22
Abstract: A control circuit for an ionizer controls an output of at least one of a positive voltage direct current (DC) power supply (PS) and a negative voltage DC PS.  Each PS is connected to at least one ionizing pin. The control circuit controls the output of the power supplies so as to cause a flow of positive and negative ions from the ionizer and directed towards a target. The control circuit includes a positive PS return current sense resistor that biases the negative voltage PS to decrease the output of the negative voltage PS when the current detected by the positive sense resistor increases and to increase the output of the negative voltage PS when the current detected by the positive sense resistor decreases. The control circuit includes a similar negative PS return current sense resistor and associated bias circuitry for controlling the negative voltage power supply.

Title: Ceramic substrate
Inventor: YUSHIO YASUHISA
IPC: C04B35/581
Filed: 1999-03-18
Abstract: The circumferential edge portion of a ductile rotating body containing abrasive grains is used to polish the surface of a ceramic substrate. The angle 8 formed between the polished direction D0 of the ceramic substrate and the rotating direction D1 of the rotating body is set in the range from 10° to 80° for the polishing step.  Alternatively, the polishing process is divided into at least two steps, and the average grain size of abrasive grains is reduced stepwise in the successive steps of the polishing process. According to this method, the surface of a large-area and thin ceramic substrate can be polished without damage, and a smooth polished ceramic surface can be provided. This method is particularly suitable for polishing a ceramic substrate having a thickness of at most 2.0 mm, and the resulting polished ceramic substrate is suitable for a ceramic heater in a thermal fixation device for fixing a toner image.

Patent CA-2410479-A1 (CA)
Inventor: JANI DHARMESH B
IPC: H04B10/00
Filed: 2001-05-24
Abstract: Optical transmission systems of the present invention include optical protection systems, apparatuses, and methods that provide increased reliability in the system. The optical system generally includes optical transmitters including transmitter controllers configured to vary the optical power of the transmitter, when degraded signals are detected in the system.  The transmitter controller controls the transmitter to transmit an output signal in a form that indicates a degraded signal condition along the optical path of the signal. The loss of signal condition can be propagated optically through the system and used to trigger a protection switch or other desired actions at various nodes in the system. In various embodiments, optical and/or electrical switches are included in the nodes along with the transmitters and/or receivers to provide redundant paths through the system, as well as into and out of the system. Upon the detection of signal degradation or a loss of signal, the transmitter controller can shut down its associated transmitter to propagate optically the degraded signal condition to the switch. Signal monitors at the switch will detect the loss of condition at the switch and initiate protection switching.
