Abstract: Process and device for dispensing electrically conductive liquids Abstract The underlying principle of the atomising process is to let the liquid out of an opening at such a low flow velocity that the initially  cohesive  thread of liquid automatically disintegrates into individual drops.  By applying an electric voltage to the thread of liquid it is then possible to generate a cone of droplets and to stabilise the drop size.  In practice this is done by passing the liquid through a large number of capillaries which are parallel from the flow-engineering point of view and act as distributing elements. Each of these capillar-ies is enclosed by a concentric protective sheath which is at the same electric potential as the capillaries. A high voltage, namely a voltage of 10 to 50 kV, applies between the capillaries and earth.  The entire device can be designed in a space-saving manner as a portable appliance and has been found to be particularly suitable in agriculture for dispensing aqueous crop protection formulations.

Abstract: SELF-FLOW GENERATING GAS INTERRUPTER     Abstract of the Invention A  unique self-flow generating gas  inter-rupter of the type wherein arc-extinction is performed by the creation of a negative pressure region brought about by the separation of the interrupter contacts.  The inter-rupter incorporates a novel arrangement of valves so as to optimize the performance of the interrupter over the broad range of interrupting currents.  In one embodiment a check valve is used  to supply gas from the exterior of the interrupter casing and into the arcing chamber in response to the pressure within the arcing chamber decreasing or falling below a pre-selected value.  In this manner, less force is required to operate the interrupter when low-currents are encountered.  In another embodiment  a relief valve is used to release the pressure developed in the arcing chamber  in the event that a large  interrupting current is encountered.  Still another embodiment incor-porates both the check valve and the relief valve.

Abstract: APPARATUS FOR MEASURING WEAR IN            THE LINING OF REFRACTORY FURNACES                 ABSTRACT OF THE DISCLOSURE            A continuous wave laser light beam is directed at the refractory lining within a furnace vessel, and the displacement as measured by a self-scanned linear array of the scattered light beam from a nominal or reference position measured to provide an indication of lining wear or damage.  The video signal received by the linear array receiver provides information for mapping the worn or damaged areas of the vessel lining so that such areas may be repaired by a gunning spray nozzle.  The inspection apparatus includes an optical filter which is temperature controlled to prevent wavelength shifts away from the nominal laser wavelength.  The electronic processing circuitry includes a voltage controlled oscillator responsive to the average background level for modifying the scan rate of the linear array to compensate for changes in background level.  The threshold against which the reflected laser beam video signal is compared is also a function of background level.  Consequently, the system is self-compensating for changes in background radiation temperature.  The apparatus may be lowered into a hot furnace vessel following each heat without the need to cool the furnace vessel.  The inspection apparatus is mechanically scanned vertically and angularly within the vessel to provide a large number of inspection data points.
