Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus for detecting electric fields and providing an indication of their magnitude includes a glass bulb containing a gas such as neon.  When the bulb is placed in a time varying electric field, pulses of electromagnetic radiation are generated within the bulb.  The number of pulses is proportional to the magnitude of the variation in the electric field.          The pulses are transmitted by a fibre optic bundle to detection and recording apparatus to provide an indication of the magnitude. Alternatively the bulb may be located adjacent a photographic film in a dosimeter and the radiation used to expose the film and provide an indication of the exposure of the wearer of the dosimeter to such fields.

Abstract: ABSTRACT "Active aerial".           An active aerial for use in car radios and aerial "arrays" comprising an aerial element and an aerial connected thereto. In order to obtain a low distort-ion  and a good  signal-to-noise ratio in spite of the presence of protection diodes to prevent overloading of the amplifier by atmospherics and in spite of conta-mination of the aerial etc, the input of the active portion of the amplifier is virtually grounded. To this end, the amplifier is preferably an operational amplifier having a high gain factor, the signal input of which is connected to ground, both the signal coming from the aerial element and a signal fed back from an output of the amplifier being applied to the inverting signal input.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of continuously depositing a metallic plating to any desired thickness on the surface of a workpiece from a non-autocatalytic electroless plating bath that is normally inherently self-limiting as to the thickness of metal which can be deposited by electrolessly plating, the novel method comprising applying an electric potential on the workpiece in the electroless bath.  The method provides non-autocatalytic baths, such as hypophosphite-reduced electroless copper baths, with the ability to plate on nonconductors to a thickness which increases with time at a rate dependent on the amount of current applied.  A more uniform thickness of deposit over the workpiece being plated and greater deposit penetration into blind holes, deep recesses and tubular portions of complex-shaped parts are obtainable by the method.

Abstract: Abstract:      The layout of an open pit mine for tar sands ore facilitates the handling of the ore by employing two or more cuts that diverge from each other while extending away from a common dump adjacent a processing (extraction) plant. Successive parallel and adjacent strips of overburden and ore are removed, whereby each cut is widened and deepened. As a result, each adjacent pair of cuts open to a common track.  Initially, this takes place in the vicinity of the dump, but, as mining proceeds a track (or ramp) is formed that is common to the two cuts while leading from each cut to the dump.  This provision of a common track shortens the haulage routes involved.  The ore is mined with large power shovels and loaded into large trucks, this equipment working down on the ore body.  For stability, a firm surface (roadway) is formed on the ore to support the shovels and trucks.  A major advantage of the system is flexibility of movement between pits and lack of restriction in mining depth and much improved ability to separate ore and reject.  The handling of tailings is also substantially facilitated, and the over-all capital cost of a large scale installation, as well as the operating and maintenance costs,can be expected to be hundreds of millions of dollars cheaper than an installation of the same capacity constructed in the conventional manner.

Abstract: ABSTRACT OF THE DISCLOSURE     A multi-processor system formed of a plurality of intelligent processing nodes interconnected by one or more transmission lines to form a shared resource cluster provides two levels of modularity which facilitate system design and growth requirements. Within each node a synchronous exchange bus interconnects processors, I/O controllers, memory controllers and serial multiplexer controllers in any combination up to a maximum total number of units, all microprocessor controlled except for global memory and the like. Each microprocessor controlled unit connected to the synchronous exchange bus includes random access memory which is functionally divided into a first portion for storing instructions and data for the on-board processor and a second portion acting as a global memory accessible by other processor controlled units on the bus. Memory address assignment for the global memory portion of each unit memory is stored in the unit in a register which is accessible by other units, so that the system can reconfigure memory address assignments by re-writing the memory address assignment in the on-board register via the bus or directly from the on-board processor. An I/O or slot address is assigned to each board as it is plugged into the bus via bus identification lines and this I/O or slot address is used to access the board for memory address assignment.

Abstract: Abstract of the Disclosure A fault monitoring and diagnostic system for a telephony switching system.  Two call processing systems connect through a programmable switch to port group units that receive individual telephone lines.  All signals from the port group units are conveyed to both call processing systems, and the call processing systems operate in synchronism.  However, the programmable switch conveys signals back to the port group units from only one of the call processing systems.  Fault monitoring and diagnositc circuitry monitors various conditions within the telephony switching system.  A test call generator automatically performs test calls thereby to diagnose system problems. If a fault is detected, the fault monitoring and diagnostic system controls the programmable switch and, in appropriate circumstances, couples the output signals from the other call processing system to the port group units. Information concerning the nature of the fault is also provided.
