Patent CA-2044903-A1 (CA)
IPC: H01Q21/00
Filed: 1991-06-18
Abstract: Cette   antenne   comprend   des   dispositifs excitateurs pour produire une onde électromagnétique plane de  fréquence  donnée,  variable  autour  d'une  fréquence centrale f0, et des dispositifs rayonnants recevant l'onde plane produite par ces dispositifs excitateurs et faisant subir à celle-ci une pluralité de réflexions successives, ces dispositifs comprenant des dispositifs pour laisser fuir vers l'extérieur une fraction de l'onde plane après chacun des rebonds successifs afin de lui permettre de rayonner vers l'extérieur.  Le déphasage de l'onde entre deux rebonds varie en fonction de la fréquence de cette onde et l'ensemble des ondes rayonnées ainsi produites présente donc un déphasage relatif déterminé, variable en fonction  de  la  fréquence de  l'onde  engendrée par  les dispositifs  excitateurs  et  définissant  une  émission présentant  un  lobe  principal  d'orientation  elle-même variable en fonction de ladite fréquence.  Les dispositifs rayonnants comprennent de préférence deux surfaces en vis-à-vis, l'une formant surface de masse et l'autre formant surface   frontale   rayonnante   perméable   aux   ondes électromagnétiques,  et des  dispositifs  pour  introduire l'onde  plane  entre  les  deux  surfaces  avec  un  angle d'incidence prédéterminé.  La présente invention peut être appliquée  notamment  aux antennes  de  radiocommunication embarquées à bord de satellites.
Patent CA-2049553-A1 (CA)
Inventor: WOOLF LAWRENCE D
IPC: C01G3/00
Filed: 1991-08-20
Abstract: A method for heat processing a superconductor wire which has a protective silver cladding includes the steps of attaching the coated wire to a spool and then rotating the spool to wind the wire around the spool in juxtaposed coils.      As the wire is being wound around the spool, the portions of the wire which are not yet coiled are drawn through a container which holds a paint that contains a silver diffusion inhibiting material. The diffusion inhibiting material is consequently deposited onto the silver cladding of the superconductor wire, and the coiled wire is subsequently placed in a furnace. The wire is heat processed in the furnace as appropriate for the particular type of superconductor material. The diffusion inhibitor material prevents diffusion of silver during the heat processing between portions of the wire which contact each other.

IPC: A01D45/02
Filed: 1991-09-06
Abstract: A harvester thresher or combine has a picking slot through which the grain stalks are pulled to separate the stalks from the grain heads.  Two oppositely rotated, parallel shafts are located at opposite sides of the picking slot.  Each shaft has at least one cutting disk in close cutting relationship with the cutting disk of the other shaft.  A vaned crusher element is mounted adjacent to each cutting disk and has its radial vanes arranged for intermeshing with the vanes of the element on the other shaft.  The tips of the vanes project outward farther than the periphery of the adjacent cutting disk for assisting in pulling the stalks through the picking slot for chopping and crushing by the cutting disks and crushing elements.

Title: Anti-corrosive rotary joint
Inventor: PETER JOHN H
IPC: F16L27/08
Filed: 1991-09-09
Abstract: ABSTRACT OF THE DISCLOSURE.     This invention pertains to a rotary joint for use with rotating machinery where the joint is conveying high temperature corrosive fluids such as molten salts.   The joint includes both a stationary head to which external connections are made and a housing mounted on and rotating with a rotary apparatus with which the joint communicates.     Alignment of the components is maintained through the interaction of two sleeve bearings disposed between a nipple coaxially extending from the head and the joint housing surrounding the nipple; the sleeve bearings being axially  displaced  from  each  other,  the  primary  seal occupying an intermediate position.  The primary seal is a spherical seal, interposed between a stationary nipple seal surface and a rotary housing sealing surface.  The seal is preloaded by means of an external joint biasing support bracket to reduce leakage under conditions of low internal fluid pressures.

Patent CA-2057649-A1 (CA)
IPC: H01S5/06
Filed: 1991-12-13
Abstract: A system for the generation of modulated optical signals, wherein the d.c. bias current of a semiconductor laser, associated with an opto-electronic feedback circuit including a delay, is superimposed with the variations of a current obtained by detecting an optical signal resulting from the combination of an optical,  amplitude-modulated input signal and of the optical signal present in the feedback circuit.  By a suitable choice of the modulation frequency of the input signal and of the low-frequency gain of the feedback loop, the laser output signal is amplitude-modulated at a frequency equal to the modulation frequency of the input signal.

Abstract: 56,703 ABSTRACT         A steam turbine blade is provided having a trailing edge portion formed from an  erosion  resistant material deposited on the blade airfoil by a friction surfacing method. According to the method, a rotating consumable rod of erosion resistant material is placed in contact under axial load against a bonding surface formed on the airfoil,  thereby causing a portion of the rod adjacent the bonding surface to be plasticized.  The rod then traverses the surface linearly leaving in it  wake a layer of erosion resistant material bonded to the airfoil by a high quality metallurgical bond. The layer is then ground to form the smooth contour desired for the trailing edge.

Title: Semiconductor protection against high energy transients
Inventor: WEBER CHARLES F
IPC: H03K17/0812
Filed: 1992-08-07
Abstract: Abstract A switching circuit is provided for protecting semiconductors such as switching transistors against transients occurring in system voltage provided by an associated source of electrical energy.  The circuit uses a switching device (18), including any number of avalanche transistors, to apply electrical energy from the source thereof to a load (20) with which it is in series.  A voltage sensor (12) monitors the system voltage and generates a transient detection signal whenever it detects a voltage transient.  A processing device (16) is used to process the transient detection signal and generate an output control signal that switches the avalanche transistors into a state of conduction so that the system voltage, including any voltage transients, appears substantially entirely across the load. Using avalanche transistors as switching transistors provides a significant margin of time for the detection, processing and switching actions to occur without damage being done to the switching transistors by a voltage transient.

Title: Cellular radio telephone communication system for multi-mode mobile radio telephone stations
Inventor: DAHLIN JAN E A S
IPC: H04W48/20
Filed: 1992-08-28
Abstract: The present invention is directed to a cellular mobile radio telephone system in which mobile stations may select either analog or digital control channels.      Analog and dual-mode mobile stations are equipped to become multi-mode mobile stations which monitor both analog and digital control channels depending on the selected mode. Downlink multi-mode mobile stations, while required to use analog control channels for call access, may nonetheless scan digital control and paging channels to receive downlink control and paging communications from the land-based system. Bi-directional multi-mode mobile stations have the same capabilities as downlink mobiles but also are equipped to transmit control information to the land station over the uplink digital control channel. If no digital control channel is available, the multi-mode mobile stations scan primary and secondary sets of analog control channels.      In this way, analog and dual-mode mobile stations may benefit from the advantages of monitoring digital control channels and digital paging channels including multiple pages per channel and battery-saving capabilities.
