Title: Circuit-testing method and apparatus
Inventor: MASON GUY
IPC: G01R27/02
Filed: 1962-04-04
Abstract: 975,973. Impedance measurements. HIRST ELECTRONIC Ltd. May 10, 1963 [April 4, 1962], No. 13018/62. Heading G1U. [Also in Division H3] An apparatus for determining the impedance required to be connected across an electrical circuit to render it effectively resistive includes a pair of terminals 25 across which the circuit is connected, a bank 47 of individually selectable reactances and a bank 49, 51 of individually selectable resistances connected together in series across the pair of terminals, a further bank 27 of individually selectable resistances connected in series between the terminals with an arrangement including a transistor 26 for applying a voltage pulse train between the terminals and across a selected resistance of the further bank, and a monitoring arrangement including a cathode ray oscilloscope 15 which can be arranged by means of a switch 46 to monitor the voltage waveform across either the selected further resistance or across the two terminals. The arrangement for providing the pulse train consists of a modified transistorised Eccles-Jordan multivibrator circuit including transistors 32, 33, which operates in synchronism with mains frequency supplied through the secondary winding 14 of the mains transformer 11, the output from this winding also being rectified to provide the power supply for the circuit. The output from the multivibrator is supplied to switch the transistor 26. The monitor includes an amplifier circuit 17 and a synchronized Miller transitron time base circuit 16 in addition to the oscilloscope. The arrangement is of particular use in testing transformer output circuits, which often give undesirable voltage spikes. For such tests, the reactance bank 47 consists of a range of capacitances. With the test circuit connected across the terminals 25, a complete series circuit exists between the power supply terminals A and B, through the electronic switch 26 and one of the resistances 27. The voltage across this resistance is monitored (by adjusting the switch 46 to take a voltage from the high resistances 29, 30 in parallel with the resistance) and the switch 28 is adjusted until the reactive effect of the test circuit is swamped and a clear pulse appears on the oscilloscope. The switch 46 is then adjusted to monitor the voltage across the test circuit, which will show a marked spike if the circuit is a transformer output. The switch 48 is then adjusted to choose a capacitance from the bank 47 such that the spike is reduced to a minimum. The resistance bank 49, 51 is then adjusted to critically damp the resonant or near resonant circuit so produced. The values of capacitance and resistance so derived indicate which components should be normally connected across the circuit under test.

Abstract: 124,413. Du Pout de Nemours & Co., E. I., (Assignees of Loomis, E. G.). March 16, 1918, [Convention date]. Camphor is purified by melting it, '' baking " the melted camphor (i.e. heating it without volatilization until the camphor oil and other impurities have been converted into bodies which are non-volatile or have different volatility from camphor), then vaporizing the camphor and condensing the vapours ; the vapours may be scrubbed before condensation. Using the apparatus shown, the crude camphor from a hopper 2 is fed by screw conveyers 4, 6 to a melting-pot 1; any vapour of water, camphor, or camphor oil formed in the melting-pot pass to a condenser 8. The melted camphor flows into an inclined pipe 10 wherein the " baking " operation is effected. The camphor then flows into the vessel 11 and is vaporized; the vapours pass through a scrubber 20 to a condenser 22, from which the solidified camphor is removed by a screw conveyer 27. The vessels 1 and 11 and the pipe 10 are heated as shown by means of pipes containing hot oil. Specification 118,489 is referred to.
