Patent BE-901508-A (BE)
Title: Leakage current detecting differential switch - comprises coils around two mains conductors connected to base and emitter of amplifying transistor
IPC: H02H3/33
Filed: 1985-01-16
Abstract: The earth of an electronic circuit is connected to an induction coil wound round one of the mains current conductors. A further connection is made to the base of a transistor from a second winding formed around the return current conductor. The windings are arranged to produce voltages in phase at the earth of the circuit and at the transistor base. - If the currents are exactly the same, there is no difference in potential between the base and emitter of the transistor (QI). No current then passes through the load resistance (R3). Any difference which arises however if the outward and return currents are not identical is multiplied and used to initiate the alarm signal.

Abstract: ABSTRACT OF THE DISCLOSURE         A system for sensing the air gap between a cutting tool and a work piece mounted on a machine for the purpose of controlling the traverse feed rate of the machine as contiguity approaches.  A drive coil is mounted on the machine. A search coil surrounds the cutting tool in proximity to the air gap and is mutually coupled (M1) to the drive coil.  A mutual inductor has first and second coils arranged so that their mutual inductance M2 is variable; these coils are connected in common at one end to a variable inductionless' resistor r.  The first coil is connected series aiding with the drive coil, while the second coil is connected in series opposi-tion with the search coil.  An a.c. source is connected across the drive coil, first coil and inductionless resistor.  The induced voltage across the series combination of search coil, second coil, and inductionless resistor provides an output which is initially nulled by adjusting M2 and r for a selected datum displacement between cutting tool and work piece.  The change in induced output voltage .DELTA.e varies in accordance with the mutual inductive M1 which changes as a function of the instantaneous displacement between the cutting tool and the work piece.  The induced voltage .DELTA.e  is then used to provide an adaptive voltage which serves to vary the traverse feed rate of the machine as required.

Abstract: ABSTRACT   A method of charging storage cells is disclosed in which the charger is automatically switched off or over to trickle charge when full charge has been reached.  In particular, the shape of the charging voltage curve is determined as a function of time automatically after the gassing voltage of the storage cell has been reached.  The charging current is switched off or over to trickle charge as soon as the increase of the charging voltage approa-ches zero.  This method mitigates the problem of overcharging the cell leading to damage of the cell or undercharging of the cell representing under-utili-zation of the full capacity of the cell.

Abstract: ABSTRACT OF THE DISCLOSURE     A heat transfer system and method for melting thick layers of ice advancing toward an object facing the ice are disclosed.  Elongated grooves or corrugations are disposed in the exterior surface of the object facing the ice.  A heating fluid is circulated in intimate contact with the inside of the grooved surface, and a force is maintained between the grooved surface and the advancing ice layer.           The grooves increase the heat transfer rate to the ice both by increasing the surface area exposed to the ice and by providing channels for controlling the flow of the melted ice liquid to initiate and maintain a forced convection mode of heat transfer that is necessary for high ice-melting rates.  A preferred application of the invention is in oil and gas exploration and production in Arctic regions where moving ice sheets must be melted to maintain a drilling platform or oil production platform positioned over a sub-merged well site during periods when moving ice fields overlie the well site.  At least a portion of the grooves have a vertical component to provide a flow path for the melted ice to the sea.  The grooves are continued above the top surface of the ice being melted.

Abstract: Abstract of the Disclosure A push-pull cable conduit is made by continuously moving a tubular mandrel through a crosshead extruding die, forming n tape of micro-porous polytetrafluoroethylene resin into cylindrical form covering the mandrel as it enters the extruding die, extruding an outer layer of fluid polymeric material over the cylindrical covering in the presence of heat, helically wrapping contiguous wires over said outer layer to form a wire layer, extruding an outer covering of thermoplastic material over the wire layer, and removing the tubular mandrel.  The porosity of the polytetrafluoroethylene covering insures a good heat bond with the outer layer of fluid polymeric material and also provides a lubricant reser-voir in its inner surface, thereby minimizing friction with the cable core and greatly reducing sound transmission.
