Abstract: 1503330 Burning waste gases HOUILLERES DU BASSIN DE LORRAINE 31 Oct 1975 [6 Nov 1974] 45348/75 Heading F4B Waste gases of low calorific value, such as by products from the carbonization of coal, which are produced at close to atmospheric pressure, are introduced through a burner 12 into a combustion chamber 1 at the available low pressure and at a temperature of 600-900 C., and not more than 80% of the stoichiometric air necessary for combustion is introduced at the level of the burner, sufficient secondary air is supplied to the base of the flame to maintain a flame temperature of 1000-1300 C., and the combustion products are discharged through a chimney. The primary air supplied to the burner 12 through passages 14 surrounding the gas nozzle 13 is controlled in accordance with the temperature at a sensor 17 in the upper part of the combustion chamber, and the secondary air supplied by nozzles 19 to the base of the flame is controlled by the temperature sensed by a device 20. Additional secondary air delivered through outlets 22 cools the vertical wall of the chamber 1. Air blown into the base of the chimney by a fan 23 is controlled to maintain the temperature at a sensor 24 in the chimney lower than 600 C. The apparatus may use the natural chimney draught, or the gases may be passed through a heat exchanger 4 by a fan 44 having a damper controlled by the chimney temperature sensor 24. The arrangement enables hot waste gases having solid particles and liquid or tarry material in suspension to be burned without first cooling the gases or passing them through a fan.

Abstract: 1,245,612. Piecewise linear function generators. WESTINGHOUSE ELECTRIC CORP. 1 Oct., 1968 [17 Oct., 1967], No. 46571/68. Heading G4G. A function generator comprises a switched feedback network (Fig. 2) wherein plural operational amplifier stages OA 1  to OA 3  may provide direct positive feedback or be inverted to provide negative feedback to the summing junction # in  with the input E in . At the inputs of the operational amplifiers the output voltage E out  and a bias voltage are combined through summation resistors at points # 1  to # 3 , and the amplifiers have feedback over blocking diodes D 11  to D 31  and in parallel therewith series diode and resistor circuits D 12 , R 14  to D 32 , R 34 ; the outputs from the diode resistance junctions of selected amplifiers being connected over summation resistors to input # 5  of a feedback inverter amplifier OA 5  feeding the summation point # in , while other selected amplifiers similarly feed the summation point over summation resistors without inversion. The series diode resistor circuits in conjunction with the bias sources operate as selective switches responsive to output signal amplitude, and the latter varies with input voltage according to the piecewise linear synthesis of a required function with bias determined break points (Fig. 3, not shown). Any desired number of stages having negative or positive feedback may be utilized and diode and bias polarities may be selected as required.

In a rectactable aircraft undercarriage of the bogie type, the bogie is, during retraction, caused to execute two consecutive rotational movements relative to the leg, viz. about an axis parallel to the transverse axis of the aircraft, and about an axis parallel to the longitudinal axis of the aircraft. The undercarriage is mounted on brackets 15 (Fig. 1) for movement between retracted (full line) and extended (chain line) positions about axes A-A and B-B, and each bogie beam 17 pivotable about a transverse axis 17<1> (Fig. 2) and a longitudinal axis 24 (Fig. 5). During retraction, the bogie is first rotated about the axis 17<1> by extension of a fluid-pressure jack 20 until a telescopic strut 21 reaches its maximum extension with the bogie beam vertical (Figs. 3 and 6, not shown). Further extension of the jack 20 produces rotation about the pivot 24 until the beam is parallel to the leg 16. The invention is also applicable to retractable undercarriages of the skid or endless-track type.

Abstract: 1443966 Electromagnetic stirring NATIONAL RESEARCH INSTITUTE FOR METALS 10 Oct 1973 [11 Oct 1972] 47395/73 Heading B1C [Also in Divisions G3 and H5] An induction melting furnace has induction coils 3, 5 around a charging section 1 and a main melting section 5', the changing and a discharging section 6 being interconnected by and being above adjacent ends of the main melting section. The coil 3 around the charging section supplies heat. Also it is used to stir the charge and, by varying single phase AC power supplied, which charges the pinch effect, is used to control the rate of efflux of molten metal from the discharge section. Similar control with multiphase AC is obtained by varying the upwardly or downwardly directed force arising from a progressive magnetic field. Control is effected by level detector 9 in the charging section and a flow rate detector 10 in the discharging section through a control device 11. If necessary power supplied to the main coil 5 can be varied to achieve the desired flow rate. The level in charging section 1 can alternatively be determined by measuring the power supplied to charging section coil 3. Temperature of the effluent metal is measured by device 12 whose output is fed to controller 13 to which is also fed the output from detector 14 sensing the power supplied to charging section coil 3. Devices 15, 15' enable the current supplied to 'be switched at will between mono- and poly-phase supply. The interior space of the furnace 4 may be either U-shaped or V-shaped (Fig. 2 not shown).

Abstract: 1,183,199. Hydraulic brake systems; valves. GIRLING Ltd. 8 Sept., 1967 [24 Oct., 1966], No. 47651/66. Headings F2F and F2V. Hydraulic brake control apparatus comprises an inlet A, an outlet B, and a piston 11 having opposed surfaces to which inlet fluid pressure can be applied. The pressure is applied to one surface directly via grooves 8 and channel 7 and to the other via a normally open inertia valve 6. Another normally open valve controls the flow of fluid from the inlet A to the outlet B and is closable in response to movement of the piston after closure of the inertia valve. With initial application of the brakes, pressure is transmitted directly from inlet A to outlet B, and thence to the rear brakes. When the retardation is sufficient valve 6 closes and piston 11 moves to the left to close head 19 on to seating 14 blocking outlet B. Further increase in inlet pressure causes head 19 to open and close on seating 14 due to the larger area of head 19 and thus transmits a reduced pressure to outlet B.
