Abstract: A fibre-optic gyroscope is provided herein for measuring an angular velocity of a fibre coil from a phase difference between a light propagating clockwise and a light propagating counterlockwise in the fibre coil. A light emitting device is provided for emitting a monochromatic light with a definite coherent length. A fibre coil includes a single mode optical fibre wound a plurality of times around a bobbin. A photodetector is provided both for making a light propagating clockwise and a light propagating counterclockwise interfere, thereby producing interference light, and for detecting an intensity of the interference light. A first fibre path is connected to the light emitting device. A fifth fibre path is connected to the photodetector. A third fibre path and a fourth fibre path are each end parts of the fibre coil. A second fibre path is provided, and a first fibre coupler is provided for coupling one end of the second fibre path to both the first fibre path and the fifth fibre path. A second fibre coupler for is provided coupling the other end of the second fibre path to both the third fibre path and the fourth fibre path. A polarizer is located in the second fibre path for polarizing light linearly. A phase modulator is furnished in one of the third fibre path and the fourth fibre path for modulating phases of lights propagating in the fibre path. A first depolarizer, consisting of a single birefringent material, is furnished in the first fibre path for depolarizing lights propagating in the first fibre path by aligning polarization planes of partial lights in all directions so that a probability of one of the partial lights having a given polarization angle is substantially equal to a probability of the one of the partial lights having any other polarization angle. Finally, a second depolarizer is furnished in the third or in the fourth fibre path for depolarizing lights by aligning polarization planes of partial lights in all directions so that a probability of one of the partial lights having a given polarization angle is substantially equal to a probability of the one of the partial lights having any other polarization angle. The light emitted from the light emitting device is transmitted into the polarizer after being depolarized by the first depolarizer.

Patent CA-2052166-A1 (CA)
IPC: A01C/
Filed: 1991-09-24
Abstract: A device for placing seed into the soil at a specific pitch in which radiating spikes of two star wheel formed discs are brought together by rotating the discs synchronously at an angle and that each of the radiating spikes has on its inner side a hollow channel forming an internal closed funnel when the spikes are brought together and opens when by further rotating the spikes move away from each other.  The means to place seed or small objects into the funnels consists of a hub disposed about the axis of rotation of the disc and mounted to rotate with the discs, which hub is provided with cells adapted to receive the seed or the other small objects and to release them upon rotation of the discs so they can fall under gravity into the funnel. The device is particularly suitable to plant seed into soil covered by a thick crop residue.

Title: Method of transcriptionally modulating gene expression and of discovering chemicals capable of functioning as gene expression modulators
Inventor: FOULKES J GORDON
IPC: C12Q1/68
Filed: 1990-07-18
Abstract: The present invention provides a method of transcriptionally modulating the expression of a gene-of-interest. The method comprises contacting a cell which is capable of expressing the gene with an amount of a molecule effective to transcriptionally modulate expression of the gene and thereby affect the level of the protein encoded by the gene which is expressed by the cell. Molecules useful in the practice of the invention are characterized as follows: (a) do not naturally occur in the cell, (b) bind to DNA or RNA or bind to a protein through a domain of such protein which is not a ligand binding domain of a receptor which naturally occurs in the cell. Additionally, this invention provides a method for determining whether a molecule known to be a modulator of protein biosynthesis is capable of transcriptionally modulating expression of a gene-of-interest.

Abstract: La présente invention porte sur une amélioration apportée à un procédé cryogénique pour la séparation de l'air en ses éléments constituants. Dans le procédé, on utilise un système à colonnes de distillation comportant au moins deux colonnes de distillation, une colonne de distillation à haute pression et une colonne à basse pression; cesdeux colonnes de distillation sont en communication thermique l'une avec l'autre. La colonne à basse pression du système à colonnes de distillation fonctionne à une pression manométrique comprise entre 9 et 75 lb/po2 et sa partie supérieure fournit un produit contenant de l'azote. Au moins 50 % de l'air amené au système à colonnes de distillation en ressort sous forme de ce produit contenant de l'azote, lequel a une concentration d'azote d'au moins 95 % et se trouve à une pression d'au moins 9 lb/po2. L'amélioration apportée au procédé est une série d'étapes permettant la production efficace de produits liquides à partir du procédé cryogénique. Ces étapes comprennent essentiellement le réchauffement partiel du produit contenant de l'azote, son expansion isentropique subséquente et l'utilisation du refroidissement inhérent à l'azote dilaté. Ces étapes peuvent se réaliser de trois manières.

Filed: 1992-05-20
Abstract: A tree delimber having a boom slidably mounted in a sleeve and means for moving the boom relative to the sleeve.   Tree feeding means are mounted on the sleeve, movable between a closed tree feeding position and an open tree receiving position.  There are tree gripping arms on the front of the boom and tree delimbing arms on the front of the sleeve.  Both gripping and delimbing arms can be selectively positioned in one of: a tightly closed position to clamp a tree;  an open tree receiving position;  and a lightly closed position to loosely hold a tree.  As the tree feeding means move a tree past the delimbing arms to delimb it, means are provided for sensing any stoppage of tree travel.  On sensing stoppage, means initiate gripping of the tree by the delimbing arms and delimbing of the tree by the gripping arms.  The invention also covers a method of delimbing with the above machine.

Title: Unipolar composite magnets and floating magnetic bearing
Inventor: LAUBE HANS-JUERGEN
IPC: H01F1/00
Filed: 1992-07-09
Abstract: UNIPOLAR COMPOSITE MAGNETS AND FLOATING MAGNETIC BEARING          ABSTRACT     A unipolar magnet is composed of a plurality of magnetic units.  Each magnetic unit is made up of a magnetic body, a magnetically conducting layer which covers the entire magnetic body except for one of the poles, and a magnetically impermeable layer overlying the conducting layer.  The exposed poles of all the magnetic units have the same polarity and together define a peripheral surface of the magnet.  The magnetic units can have the configuration of a segment of a ring and can be assembled to form an annular first magnet whose external peripheral surface is constituted by the exposed poles.  Several of these annular first magnets can be superimposed to form a hollow cylinder, and such a cylinder can be used to construct a shaft capable of floating in a housing.  To this end, the housing is provided with annular second magnets which surround the first magnets.  The internal peripheral surfaces of the second magnets have the same polarity as the external peripheral surfaces of the first magnets thereby causing the shaft to float radially.  The housing and the shaft are provided with additional magnets which are superimposed with one another as considered in axial direction of the shaft.  Each additional magnet on the shaft confronts an additional magnet on the housing.  The confronting magnets are arranged with like poles facing one another thereby causing the shaft to float axially.
