Abstract: In bottom blown oxygen steel making or in top and bottom blown combined oxygen steel making, the tip end of a tuyer immersed in molten steel is seriously damaged or melted away due to very high temperatures due to the vigorous combustion of carbon, manganese and so on by the oxygen blown into a furnace. 
     In order to prevent such damage, hydrocarbon gas has been blown through space between an outer pipe and an inner pipe of a dual pipe tuyere or tuyeres, but such hydrocarbon gas rather excessively lowers the temperature of the molten metal adjacent to the tip end of the tuyere and often blocks the opening of the tuyere. 
     Now, instead of blowing in hydrocarbon gas, particulate material such as limestone magnesite, dolomite and the mixture thereof are proposed to be blown into the molten metal in the decarburization steel making vessel carried by an inert gas, combustion gas, blast furnace gas, LD process gas and oxygen or a mixture of these gases. 
     Particulate material mentioned above, when blown into the molten metal, increases the momentum of the gas flow, enhances a shielding effect, against high radiation heat by fire point, or further forms either a kind of protective layer or deposit of refractory mineral material at the tip of the tuyere thereby effectively preventing damage of the tuyere and lengthens the service life of the refining vessel. 
     Addition of particulate material in continuously linearly or in stepwise manner has been proved to be effective for accomplishing the above-mentioned cooling and protecting effect of the particulate material.

Abstract: Apparatus for gathering data about a plurality of chemical or physical conditions, e.g. on industrial plants utilises a plurality of passive optical sensors (93). Light for the sensors is provided by a common broadband source (90), and distributed by an optical fibre (91) from which light of a selected colour is withdrawn (92) for each sensor in turn, the colour selected for each sensor being different from that selected for the other sensors. Each colour is modified by its respective sensor as a function of changes in the conditions applied to the sensor, and all the modified colours are conveyed along a common data bus to be demultiplexed and the data displayed. The colours may be supplied by the data bus to detection means simultaneously or sequentially. Passive optical sensors (93) avoid electrical interference and incendiary risks due to electrical sparking, and colour multiplexing avoids difficulties associated with other forms of multiplexing in plant environments.

Abstract: An amorphous silicon PIN semi-conductor device is manufactured by (i) providing a substrate (10) with a layer (11) of an electroconductive material, for example molybdenum, which forms an ohmic contact with N+ amorphous silicon; (ii) sequentially sputtering a layer of N + doped amorphous silicon (12), a layer of intrinsic, I, amorphous silicon (14) and a layer of P + doped amorphous silicon (16). A layer (18) of an electroconductive material, for example semi-transparent indium tin oxide, is sputtered into layer (16) to form an ohmic contact therewith. A grid current- collection electrode (20) is optimally patterned on layer (18). The sputtering step parameters are controlled, and the steps can be performed in a single vacuum system and vacuum pump-down procedure. The semi-transparent layer (18) can thus be depointed on a thin P+ doped layer (16) without deterioration of the junction forming characteristics of the underlying amorphous silicon layers.

Abstract: A spray gun for dispensing plural component materials, such for example as polyurethane foam or plural component paint, mixes the components externally of the gun, not in the gun, so that flushing of the gun is not required when spraying is stopped. This is accomplished by providing a hollow and ported needle valve (66) in the gun, introducing one of the components into the gun and around the needle (82, 84, 86) and the other component through the port (70) to the interior of the needle (92, 98, 100). When the gun is off, the forward end of the needle seats against a fluid nozzle (32) to prevent spraying of the one component and the port (70) in the needle is sealed off from the supply of the other component. To spray the components, the gun is triggered to move the forward end of the needle (66) from its seat with the fluid nozzle (32) and to position to port (70) in communication with the supply (92, 98, 100) of the other component, whereby both components are emitted from the gun, the one through the space between the needle and nozzle (86) and the other through an opening at the forward end (102) of the needle. Air jets (62, 64) atomize the spray and form the same into a fan-shaped pattern.

Abstract: An arc suppression device (40) for protecting the load carrying contacts (30, 31, 32) of a power contactor (20) includes gate controlled semiconductor devices connected in parallel with the contacts. A signal from a control circuit (45) causes gating current to be applied to the semiconductor devices nearly simultaneously with the application of current to and removal of current from the solenoid (25) of the power contactor. A source of gating current of sufficient magnitude and character is provided to gate each thyristor into the conducting state substantially immediately. The source of gating current may be either direct current or high frequency alternating current. Circuit means responds to the control signals to provide the gating current for a limited period of time prior to, during and following the closing of the contacts Gating current is not continued after the contacts have closed to protect the semiconductors from possible damage Additional circuit means responds to the removal of the control signal to provide gating current for a limited period of time prior to, during and following the opening of the contacts. An isolation relay may be provided to prevent leakage current from flowing through the semiconductor devices to the load while the power contacts are open.
