Abstract: 1388159 Moulding superplastic alloy sheets; making decorative panels ISC ALLOYS Ltd 30 May 1973 [14 June 1972] 27891/72 Headings B3A B3V and B3Q Superplastic alloy sheet conformed to a mould surface is removed from the mould and then, while suitably supported, subjected to a temperature of 180-220‹ C. to remove warping or distortion. In an example, a wall panel at 250‹ C. was moulded for 12 minutes using compressed air at 60 lbs. per square inch. The panel was distorted upon removal from the mould and was stored, being subsequently placed on a flat hot plate at 200‹ C. and free from distortions within 15-20 minutes; In a further example, a sheet was moulded for 6 minutes at 250‹ C. and at 150 lbs. per square inch air pressure. The moulding was removed by cooling it around the peripheral flange and allowing it to fall on to and be distorted by a lower platen. The distortion was removed by inverting the hot moulding and cooling it for 1 hour on another mould of complementary shape. Heat treatment of the moulded sheet preferably takes at least 10 minutes in an oven, or heat remaining after the moulding operation may be used. Either surface of a moulded sheet may be cooled by air or water to facilitate its removal from the mould after pressure or vacuum forming. Zinc-aluminium alloys are referred to containing 15-40 weight per cent Al, preferably 18-30%, with or without up to 0À5% of, for example, Cu or Mg. Methods of removing mouldings are acknowledged in which the formed component is heated above the superplastic range, e.g. by contact with a heated die at the end of forming. Alternatively, contact with a cold die may destroy superplasticity, or both the component and die are cooled.

Title: Improvements in or relating to electric signal generators
Inventor: ELBOURN ROBIN WILLIAM
IPC: H03K4/12
Filed: 1955-10-04
Abstract: 799,530. Sawtooth wave generating circuits. RANK CINTEL, Ltd., [formerly CINEMATELEVISION, Ltd.]. Oct. 3, 1956 [Oct. 4, 1955], No., 28219/55. Class 40 (6). A waveform generating circuit comprises a capacitor having first, second and third circuits for changing the charge on the capacitor at predetermined rates and first, second and third circuits responsive to the voltage across the capacitor for operating in conjunction with triggering circuits for controlling the charging circuits in order to generate the required waveform. Fig. 3 shows a single stroke circuit for generating a sawtooth balanced wave with respect. to a reference voltage. In the inoperative condition of the circuit the voltage across a capacitor 12 is clamped to a reference voltage 21 by means of diodes 18 and 20. The application of a triggering pulse to terminal 22 operates a trigger circuit 25, 28 applying a pulse to the grid of valve 31 rendering the valve non- conductive. A diode 34 accordingly becomes conductive and the capacitor 10 discharges rapidly through resistors 35 and 17. The voltage across the capacitor is applied to the grid of a flip-flop 36, 37 and when the voltage reaches a reference value applied to the grid of valve 37 (in this case earth potential) the flip-flop operates applying a pulse to the valve 40 causing the trigger circuit 25, 28 to be reset. This renders valve 31 conducting again blocking diode 34 and so interrupting the discharge path of the capacitor. Accordingly the capacitor now charges slowly through a continuously operative charging circuit comprising resistors 11 and 12. The rise of voltage at the cathode of valve 31 when the valve was rendered conductive is applied to a differentiating circuit 41, 42 to operate a trigger circuit 45, 46. The output of this circuit is applied to the grid of a valve 49 to render the valve conducting and so block diode 18 permitting the capacitor to charge beyond the original reference voltage 21. The charging continues until the voltage applied from the capacitor to the input grid of a flipflop 38, 39 exceeds a reference voltage applied to the grid of valve 39 when an output pulse is produced which is applied to valve 50 to restore the trigger circuit 45, 46 to its initial condition. The output from this trigger circuit cuts off valve 49 so rendering diode 18 conducting and causing the capacitor to rapidly discharge again through resistors 19 and 17 until the original reference potential 21 is reached. The voltage across the capacitor is applied via a cathode follower valve 13 to an output terminal 14. The charging of the capacitor is linearized by applying part of the output through capacitor 15 to the junction of resistors 11 and 12 and the discharging is linearized by connecting a tap on the cathode load 16, 17 to the discharging resistors 35, 19.

[Also in Division H2] A plurality of power amplifying means in parallel with common input and feeding a common load are arranged to carry equal fractions of the total load current by the inclusion of a plurality of transformers which sense the individual fractions and are coupled together to generate a correction signal to equalize the fractions.

If one transistor takes more current than the others (e.g. if it has a higher beta), the corresponding secondary winding will generate a higher voltage which sends a current round the loop to induce voltages in the other three primaries in a sense to increase the currents in the other three transistors. The invention can also be applied to common-collector circuits (Fig. 2, not shown) or to PNP transistors.
