Patent CA-2007778-A1 (CA)
IPC: H02H7/26
Filed: 1990-01-15
Abstract: A directional comparison  relaying  system includes  forward  looking  pilot  relays  at  each terminal of a protected line segment and monitors which detect predetermined  incremental  changes  in line currents and voltages indicative of a fault. These predetermined incremental changes in current or voltage, which can be detected before the pilot relays  respond,  generate  local  blocking  signals which  are  transmitted  to  the  other  terminal  as remote    blocking    signals    over    a    two-way communications channel.   Trip signals for tripping circuit  breakers  at  the  associated  terminals  are generated from forward fault signals produced by the pilot  relays  but  are blocked by  the presence  of either a local or remote blocking signal.   However, the forward fault signal cancels the local blocking signal and the corresponding remote blocking signal at the other terminal so that when both pilot relays see an internal fault, the circuit breakers at the two terminals are tripped simultaneously.   Either a reverse direction distance relay or a reserve ground current relay and a zero sequence current monitor, generate a transient blocking signal which maintains the  local  blocking  signal  and  its  corresponding remote blocking signal at the other terminal,  and blocks a trip signal during transient fault clearing in other line segments to prevent overtripping.

Title: Ultrasonic control head and its application to the control of parts whose shape evolves during production
Inventor: FLORET MICHEL
IPC: G01N29/24
Filed: 1990-02-01
Abstract: So as to control parts of any form, such as panels made of a composite material, a control head (10) is used comprising a small bar made of an elastic material, aligned ultrasonic transducers (18) being placed in said control head which functions by reflected light. The small bar bears contact blocks (22,29) which are brought into support on the surface of the part to be controlled, which has the effect of deforming t he small bar and orientating each of the transducers perpendicular to the surface. As regards parts having a non-uniform shape, a uniform quality of the control is thus ensured, the same applying for a reduction of the control time. A precise control of the evolution of the structure of parts during production is also rendered possible. Advantageously, the transducers are mounted on the small bar so as to be disassembled, said mounting being effected by means of wedging members, such as screws and metal wire clips:

Patent CA-2011511-A1 (CA)
Title: Laser radar system
Inventor: HINZ ALEXANDER
IPC: G01S7/48
Filed: 1990-03-05
Abstract: Abstract of the Disclosure The invention is directed to a laser radar method for measuring velocity of moving objects wherein the laser light reflected from the measured object is coupled back into the laser resonator and then conducted to a heterodyne receiver.          An amplification effect is produced by the interaction of the reflected signal with the laser active medium and the resonator and this amplification effect produces an improved signal/noise-ratio and makes possible a simpler configuration of the measuring arrangement.

Title: Target for close in weapon systems
Inventor: ROBINSON PAUL R
IPC: F41J9/10
Filed: 1990-03-15
Abstract: A B S T R A C T            This invention relates to a target which is towed by an aircraft to simulate the approach of an aircraft, missile or similar threat to a Defence System, to provide realistic practice for the Defence System.  In accordance with this invention there is provided a target that is connected by a cable to a tow aircraft and towed by the aircraft toward a Defence System at a low approach altitude.  The target has flight surfaces that, in combination with the mass of the target, cause the target to be towed at a substantially lower altitude than the tow aircraft.  This allows direct ground or sea skimming approach by the target as the tow aircraft overflys the Defence System.  The target is provided with a cable release means that releases the target at a predetermined safety range, whereupon the cable rises to a free streaming height and clears the Defence System.

Title: Compact padding machine
Inventor: BISHOP WILLIAM B
IPC: E02F7/00
Filed: 1991-03-25
Abstract: A compact padding machine for screening and conveying soil into a trench. The machine is usable as an attachment to a conventional bucket loader, bulldozer or other base machine. The padding machine includes a screening belt, an underlying inclined conveyor belt, and a transverse, extendible discharge conveyor belt. Soil is collected and conveyed upwardly on the screening belt. Fine grained soil passes through the screening belt, is deposited onto the inclined conveyor belt, and is discharged therefrom onto the transverse conveyor belt, from where it may be conveyed into an adjacent trench. A hydraulic vibrator is coupled to the screening belt to disaggregate clod of fine-grained soil and cause the soil to pass through the screening belt. Rocks and other large objects are conveyed to the rear of the machine and discharged. An auxiliary attachment may be used to collect discharged rocks and convey them away from the path of the following base machine, either by conveying them into the trench, on top of the screened soil, or by conveying them to the opposite side of the padding machine, away from the trench. A pivotable auxiliary conveyor belt is also available to enable screened soil to be discharged at variable distances from the machine.

Filed: 1991-06-20
Abstract: A  telemetry   supervisory   system   for  transmitting information by means of an asynchronous transfer mode technique in a broadband integrated services digital network (B-ISDN), is disclosed.   The system comprises a monitoring means for monitoring a state of an object and for generating monitoring information  related  to  the  state  of  the  object;  and encoding/transmission  means  for  encoding  the  generated monitoring information into a number of cells of fixed length using a variation coding technique, such that 1) when no change in  the  state  of  the  object  occurs  and  less  monitoring information is generated, the cells are generated at a given rate defined as number of cells per unit time, and 2) when a change of the state of the object occurs and more monitoring information is generated, the cells are generated at a new rate, wherein a variation of the given rate to the new rate corresponds to a magnitude of change of the state of the object.  The encoding/transmission means transmits the cells of fixed length to a monitor station in an asynchronous transmission mode through a communication network. The monitor station includes 1) a cell number counter for counting a number of cells per unit time received from the communication network; and 2) a cell number increase detection means connected to the cell number counter and outputting an alarm signal which identifies a monitored object, when a change of the number of cells counted by the cell number counter is larger than a predetermined value.
