[Also in Divisions C7 and H5] In electro-slag remelting apparatus using D.C. superimposed on A.C. with an auxiliary non- consumable electrode 5 dipping into the slag 4, the strength and direction of the D.C. flow in the slag is controlled in order to control the reactions between the slag and the molten metal, e.g. steel, such as desulphurization or deoxidation. The slag is substantially ionized and the individual ions are moved in the slag by superimposition of a direct current. The A.C. is applied between the consumable electrode 2 and base-plate 3 from a single-phase transformer 1, Fig. 1, and the D.C. is applied via rectifiers 6, a reversing switch 7, a regulating resistance 8 and a switch 9, the latter switch allowing for the supply of A.C. to the auxiliary electrode system 5, if desired. In the multi-phase embodiment, Fig. 2, a further rectifier 10 is arranged between the metal joint and the auxiliary electrode system 5, which is a tubular electrode of graphite, Mo or W, or may be several rod-shaped electrodes equally spaced around an imaginary cylindrical surface. The sulphur or oxygen impurities may be removed from the molten steel or, by reversing the polarity of the D.C., the sulphur is kept from passing into the slag from the steel.

An annular flame tube for a gas turbine engine has control means for decreasing the secondary combustion air flow while simultaneously increasing the dilution air flow and vice versa. In one arrangement the flame tube has a series of angularly spaced primary combustion air inlets 50 each provided with swirl vanes. Secondary air is introduced into the flame tube through nozzles 51 leading from annular passages inwards and outwards of the tube, whereas dilution air is introduced through nozzles 52, 53, the nozzles 53 being supplied via ducts 54. The ratio of dilution to secondary air can be varied by deflector vanes 55 movable axially from the position in which they cover the intakes to ducts 54 to the position in which they cover nozzles 51. In a modification, Fig. 3 (not shown) the dilution/secondary airflow ratio can be varied by an axially movable part (100) of the flame tube wall. In a further arrangement, Fig. 5 (not shown) the ratio can be controlled by rotatable walls (110, 111) carrying valve members (112, 113 and 116, 117) which respectively co-operate with the secondary and dilution air nozzles. In a further modification Fig. 7 (not shown) the secondary and dilution nozzles (130, 131) are controlled by valve members (132, 133) on opposite ends of rockable levers (134).

Abstract: 1289728 Periscopic scanning systems AGA AB 11 Nov 1969 [29 Nov 1968] 55153/69 Heading G2J [Also in Division G1] A scanning device for sensing infrared radiation comprises a rotatable unit U containing a reflector DM and two optical systems OS1 and OS2 whose axes A1 and A2 are perpendicular to the axis of rotation X, an infrared detector DE responsive to radiation from the system OS1, and either a reference light signal generator or an optical viewing system SM in optical contact with the system OS2. For a pre-selected proportion of each complete rotational cycle the detector DE is responsive to the infrared radiation incident upon it through the system OS1 and a filter F to produce on an oscilloscope screen SN to plot of infrared intensity against angular position. This pre-selected scan period is governed by a cam disc rotating at the same angular velocity as the unit U, Fig. 2 (not shown) and which produces a pulse A during which the oscilloscope displays the detector output. The cam disc also generates a pulse B of the same duration but 180 degrees out of phase with A, and pulses A and B are applied to a sweep generator SW whose output is a series of sawtooth pulses which are applied to a variable voltage comparator CP. The output from CP is a train of pulses, the width of back pulse being determined by the setting of the potentiometer PM. These pulses form the input to a clipping circuit DCC whose output is a train of short duration pulses E, of which only those derived from the pulses B pass through an AND- gate AN. The output pulse BE from AN actuates a signalling device PG (SM) to produce a light pulse which is transmitted through the system OS2 to illuminate a section of that field of view that OS1 was viewing 180 degrees earlier. This pulse BE is also applied to the CR0 SN alternately with the output from the detector DE for each revolution of the unit U. The display on the CRO screen therefore consists of a trace A" of the infrared intensity across the field of view being scanned, together with a pulse E" whose position with respect to the trace is analogous to the position of the light pulse in the scan area. The position of the emitted light pulse within the scanned area may be changed by altering the setting of potentiometer PM.

The boundary line between the high velocity gas flow B discharging from the nozzle and the low velocity air flow from the annular space 5 is indicated by chain-dot line 6, the flow discharging through the outlet 3 of the duct 2. A series of aerodynamic members 7 is disposed within the duct 2 in the low velocity air flow and acts to vary the circumferential static pressure distribution of the low velocity flow so as to induce perturbations at the primary jet boundary. Openings 8 are provided in the duct 2 through which additional air flow may be introduced into the disturbed flow region. The openings 8 are normally closed by a pair of pivotally mounted shutters, the shutters being partially opened for inflow of air when noise suppression is to be operative.
