Title: Automatic assistance system for trainee VDU users - has microprocessor programmed to display operator action and responses through communications interface
Inventor: BESTOUGEFF ALEXANDRE
IPC: G09B5/14
Filed: 1980-07-30
Abstract: The system is used for assistance to a VDU uses at an actual work station and comprises a microprocessor (4) programmed to establish and maintain a dialogue with the VDU (1). The VDU contains a data receiver and controller (12) and a display (110 which enables the operator actions to be displayed as well as the responses from the microprocessor. The display devices include lamps or dials as well as a TV screen. The display is controlled by self contained circuits activated by the microprocessor through a communications interface (2) and connecting cable (3). This interface ensures that the information for operator assistance is routed to the VDU when an external computer system is connected.

Title: Subscriber line connection adaptor - procures power for accessory unit and has constant current and voltage limiter elements
Inventor: DINNISSEN PAULUS
IPC: H04M19/08
Filed: 1980-09-18
Abstract: The telephone set (HS) as well as an accessory unit such as a loudspeaker amplifier (Z) is to be fed from the d.c. supply current available from the a-C subscriber connection lines in such a manner that neither too much current is drawn nor too little which would result in the supply voltage rising above the permitted limit on short lines. A constant current device (I) is placed in series with the telephone set (HS) feeding it with no more than the minimum required current but allowing a.c. speech variations to be bypassed by a capacitor. The accessory (Z) is suppled with constant operating voltage via supply lines (p-m) from a regulator (Q) which contains a voltage dependent bleeder circuit for absorbing voltage surges, and a zener controlled constant voltage output stage.

Patent FR-2493538-A1 (FR)
Title: Demountable optical fibre connector - uses axial compression generated by buckling fibres with retracting piston in plug to protect fibre when disconnected
Inventor: MALAVIEILLE FRANCOIS LOUIS
IPC: G02B6/38
Filed: 1980-11-04
Abstract: The protective sleeve is stripped back from the fibre and the fibre is threaded progressively into a guiding sleeve positioned centrally to mate the fibre ends together with the required precision. Each of the fibres, in being brought together, is buckled so that the ends are held in contact with an effective but not excessive pressure to ensure good light transmission using the force provided by the elasticity of the fibres themselves. The guide has a cylindrical body with a central channel of diameter close to that of the fibres with conically flared ends. The fibres are guided to slide on the inside of the flare into the channel. The guide is fixed by the flared ends to the body of the connector. The tubular plug has a conical washer which grips the sleeving of the fibre by compression. It contains a sliding piston held by a compression spring positioned by a washer which protrudes to protect the delicate fibre if the connection is removed. The cap of the plug is screwed onto the body of the connector retracting the piston and allowing the fibre to slide into the guiding sleeve. There is a friction washer between the cap and the plug body.

Title: Gas exhaustion arrangement for high-current circuit breaker - uses expansion chamber in form of convergent duct with circulation blocks to exhaust arc gases to atmosphere
Inventor: BLANCHARD CHRISTIAN
IPC: H01H9/34
Filed: 1981-08-06
Abstract: The gases generated during operation of electric circuit breakers are released from the arcing chamber into an expansion chamber coupled to the arcing chamber. A decompression chamber in the form of ducts (31,32) is formed in a volume above the arcing chamber. Holes (19,20) are provided in the wall separating the arcing chamber from the expansion chambers to allow passage of the gas. The expansion chambers are shaped to form a stepwise convergent duct, leading the arc produced gases to atmosphere. To reduce circulation of gases, in the expansion chamber a narrow neck may be incorporated in the outlet path, or alternatively a restriction such as a chicane, grille, perforated sheet or parallel bars may be placed near the gas outlet (35).

Title: Lightning protector for overhead distribution line transformer - includes voltage balancing spark gaps linking medium and low voltage circuits
Inventor: LEDOUX CHARLES
IPC: H01C7/12
Filed: 1981-10-12
Abstract: The appts. includes an arrangement of three spark gaps connected in a Y configuration for each of the phase conductors and the neutral line of the low-voltage three phase network. Two of the spark gaps are connected to terminals (A,B) on either side of a circuit breaker (D) in this line. They are then connected together at their second ends, and this common point forms one contact for the third circuit breaker which is connected to earth (T). The earth point is common to both the low voltage and medium voltage sides of the transformer, so whichever side is the origin of an overvoltage there is a partial coupling equalising the voltages. The spark-gaps may be in series with semiconductor resistance components, or may be formed by zinc oxide elements.

Patent FR-2519674-A1 (FR)
IPC: E04D13/10
Filed: 1982-01-06
Abstract: The device has an elongated support on which a cutting part is mounted so as to be movable relative to the support. The support is laid onto the snow masses overhanging the roof in such a way that the cutting part can pass into the region of these snow masses. By to-and-fro movement of the cutting part in relation to the support, the overhanging snow masses can be sawn off. The support itself is of such length that it can be set up on the ground and leant against the snow masses on the roof. As a result, it is not necessary to climb onto the building roof to remove the snow masses.

Title: Electric motor protective device preventing in case of stalling - uses vibration detector to initiate removal of supply if motor vibration frequency is incorrect after start-up delay
Inventor: DOUCHET JACQUES
IPC: H02H7/093
Filed: 1982-03-03
Abstract: The protective device opens the supply circuit to the motor if the rotor stalls due to seizure of the load mechanism or for any other reason. A circuit breaker (2) is activated by a detector circuit which compares the motor vibration frequency with the frequency at the normal running speed. A delay circuit (5) prevents operation of the detector during motor starting. The vibration detector (1) output passes to a high-pass or pass-band filter (9), the output of which is coupled to a threshold detector (11). If after the start-up delay the vibration frequency falls below the set frequency the trip contact is closed, initiating opening of the supply to the motor.; motor.

Title: Medium voltage DC arc-quenching circuit breaker - operates at voltages of order 2000 volts and provides large inter-contact gap
Inventor: GELEZ JEAN-PHILIPPE
IPC: H01H50/64
Filed: 1982-03-19
Abstract: The circuit breaker offers advantages over existing types in that it creates a larger than usual separation of electrical contacts, decreases contact deterioration, allows mechanical indication of contact closure and can be operated manually. A fixed insulating housing has a solenoid coil which causes the axial movement of a ferro-magnet core when energised. The amount of displacement can be varied by adjusting the magnetic gap between the moving core and a fixed one. The axial displacement is communicated to a moving contact head by a lever pivoted about a fixed axle at one end. The length of this lever and position of the pivot point provide mechanical amplification of the movement. The two circuit contacts have concave surfaces and are connected to external cable terminals. The moving head has a shorting contact with two pads which bridge the fixed contacts when the breaker is not energised.
