Patent CA-2133941-C (CA)
Title: Method and apparatus for moving a drawbar between transport and operating position
Inventor: BOYKO STANLEY
IPC: A01B49/00
Filed: 1994-10-20
Granted: 2000-01-18
Abstract: An agricultural drawbar adapted to be pulled by a power source and used for farming operations such as spraying or harrowing, is equipped with right and left wing booms which are adapted to be folded or unfolded from the transport to operating positions.  To enable the drawbar to move more quickly and easily from one position to another, lockable inner caster wheels are attached to a tensioning/control assembly which is attached to the cart. During the folding process the inner lockable caster wheels are progressively turned as the wings move to the folded transport position, thus easing the implement quickly into the transport position without skidding or binding of the wheels.  Furthermore, a semi-lockable outer caster wheel is adapted to rotate inwardly to a toe-out position to facilitate the unfolding of the drawbar when the drawbar is pushed rearwardly.

Abstract: Filters for filtering molten light metals comprise a reticular foam formed from a composition comprising graphite, wollas-tonite, silica and a borosilicate glass and consist of a crystalline phase comprising graphite and wollastonite dispersed in a sub-stantially amorphous matrix of botosilicate glass. The filters can readily be machined accurately from large pieces of the filter material and they do not pick up moisture from the atmosphere when stored. The borosilicate glass used to produce the filters preferably has a softening temperature (T1) in the range of 600 °C, more preferably 650 °C to 900 °C and a melting tempera-ture (T2) in the range of 700 °C to 1100 °C, as measured according to the tests in German Standard DIN 51730.

Abstract: Un procédé permet de récupérer la lécithine contenue dans des mélanges d'huile et de lécithine par extraction au moyen d'un agent d'extraction contenant au moins un hydrocarbure. L'extraction au moyen d'un ou plusieurs hydrocarbures C3 ou C4 est effectuée dans des conditions menant à la formation d'une solution de faible viscosité par l'agent d'extraction avec la lécithine. Le mélange d'extraction se décompose ensuite en une phase liquide riche en huile et en une phase liquide riche en lécithine. On sépare les deux phases et on récupère une huile sensiblement dépourvue de lécithine par séparation de l'agent d'extraction contenu dans la phase riche en huile et une lécithine pure sensiblement dépourvue d'huile par séparation de l'agent d'extraction contenu dans la phase riche en lécithine.

Title: Detection of nucleic acid amplification
Inventor: NADEAU JAMES G
IPC: C12N15/09
Filed: 1995-03-28
Granted: 1998-06-30
Abstract: Fluorescence polarization methods for detection of nucleic acid amplification. Afluorescently labelled oligodeoxynucleotide probe is converted from single- to double-stranded form in a target dependent manner during amplification of the target sequence. This conformational change is accompanied by an increase in fluorescence polarization values. The increase in fluorescence polarization can be measured on a transient-state fluorometer in real-time during the amplification reaction without any physical manipulation of the sample. The inventive methods therefore provide a closed, homogeneous system for both amplification of target sequences and detection of amplification. Alternatively, amplification may be detected in the fluorometer after the amplification reaction is completed.

Title: Bearing arrangement with gravity-fed lubrication
Inventor: KALLENBERGER HARVEY J
IPC: E02F3/58
Filed: 1995-07-24
Granted: 1998-09-01
Abstract: The disclosure involves a new "pancake-like" thrust bearing arrangement with gravity-fed lubrication.  The bearing is angular to a horizontal plane and has a top edge above such plane.  A load-support structure oscillates on the bearing.  Such bearing has a lubricant feed aperture at the top edge and plural lubrication grooves formed in the flat bearing face and connected to such aperture by feed passages.  The grooves are oriented so that they "run downhill," i.e., so that they intersect a circle concentric with the bearing center.  Grease moves by gravity along the grooves which are "closed-ended" to help prevent premature expulsion of grease from the bearing face.

Title: Coating method and coating apparatus
Inventor: KITAMURA YOSHIYUKI
IPC: B05C9/02

Granted: 2006-08-08
Abstract: The present invention relates to coating methods and coating apparatus suitable for the stable production of coatings on the flat surface of sheet substrates, and methods for manufacturing coated sheet products such as color filters.      An embodiment of the coating method according to the present invention is a coating method wherein a coating liquid feeder supplies coating liquid to a coating liquid applicator having a coating liquid discharge slot, with at least either the coating liquid applicator or a substrate to be coated being moved relatively one to the other to form a coating with a predetermined thickness on the substrate, comprising the steps of: keeping at rest the substrate at a position where the start-of-coating line of the substrate is in register with the coating liquid discharge slot of the coating liquid applicator; commencing discharge of the coating liquid through the coating liquid discharge slot; forming a coating liquid bead which is in contact with both an exit aperture portion of the coating liquid discharge slot and the start-of-coating line of the substrate; and subsequently commencing movement of at least either the coating liquid feeder or the substrate relatively one to the other.      A coating method of this embodiment makes it possible to accurately determine the start-of-coating line and form a high accuracy coating, because by this method, after discharge of the coating liquid starts while the substrate to be coated is still at rest in register with the coating liquid discharge slot and the formation of the coating liquid bead is assured, the substrate is moved relatively to the coating liquid discharge slot while rendering the coating liquid bead stable.
