Abstract: ABSTRACT              To permit ease of manufacture and eliminate the necessity to apply a heater to the inside of a closed tube, a solid electrolyte, in elongated plate form is located within a housing which includes a sealing element separating the elongated plate into two portions; one portion is exposed to the gas to be tested, the other portion separated from the first portion by a gas tight seal positioned in the housing is exposed to a reference gas, typically the oxygen in ambient air; the elongated plate extends to a terminal end portion retained in a ceramic holder for example by means of a plastic bushing, formed with an opening to permit access of the reference portion to ambient air. Preferably, the electrodes are applied to one major surface of the plate, the opposite side having one or more heater elements applied thereto, for example by printing or vapor deposition and in alignment with the respective electrodes.

Abstract: ABSTRACT          IMPROVEMENTS IN OR RELATING TO THE COUPLING OF        DIELECTRIC OPTICAL WAVEGUIDES         A pair of optical fibres which are to be joined are located with their end portions in coupling elements one of which is transparent to light.  The coupling elements are located such that the ends of the fibres are in approximate alignment.  Light is transmitted along one fibre so that it is received by the fibre is the transparent coupling element.  Light which is not coupled into the core of the fibre is sensed by a sensor and the relative position of the fibres is adjusted until the level of sensed light is a minimum.  The sensing of the light is carried out at positions spaced angularly about the waveguide so that an indication of the direction of any misalignment is obtained.  The coupling elements are then secured in this position.  The adjustment of the fibres can be carried out using a linear translation stage and a microprocessor which controls the stage in accordance with signals from the sensor.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus or process for casting metals by electromagnetically forming molten metal into a desired shape by applying a magnetic field to the molten metal. The magnetic field defines a containment zone for the molten metal.  The hydrostatic pressure exerted by the molten metal in the containment zone is sensed and in response thereto the flow of molten metal into the containment zone is controlled.  This minimizes changes in the hydrostatic pressure.

Abstract: ABSTRACT   A compression ignition engine having a pilot fuel feed to the engine and a separate gaseous fuel feed characterized in that the separate gaseous fuel feed is controlled by means controlled by hydraulic pressure dependent on engine speed and/or engine load.   A feature of importance is that for each engine speed when the engine is running the hydraulic pressure has a pre-determined maximum value, there being bleeding off circuitory or other means to enable reductions of hydraulic pressure below said maximum value for each speed.  With such a means it is possible under low load conditions for engine speed governor means to cause the bleeding off circuitory or other means to cause a reduction in hydraulic pressure and hence gaseous fuel feed to engine at the particular engine speed.          Such a compression engine retrofitted or otherwise to pro-vide the features of the present invention has application with both standing and mobile action.
