Locating tabs 7 are arranged to engage apertures (3), Fig. 3a (not shown), in a magnetic sheet 1 on which are recorded a plurality of sets of signals, each set including a question signal (A), a stop signal (B), a correct answer signal (C), a time interval signal (E) representing the time limit within which the question should be answered and optionally an explanation signal (D), Fig. 1 (not shown). The apparatus also includes a power switch 1, a volume control knob 12, a rapid feed button 13, a play-back button 14, a rewind button 15, answer buttons 16 to 18, a correct answer indicator lamp 19, a wrong answer indicator lamp 20, and a safety switch 21 located so as to be operated by the weight of a transparent cover 8. In use, the magnetic sheet is positioned on the upper panel 5 and the cover 8 is lowered to operate the safety switch 21 to enable the unit to be energized when the switch 11 is turned ON. With the play-back button 14 operated, the student can listen to the question through headphones or a speaker, until detection of the stop signal interrupts play-back and actuates a counter. The student then presses one of the buttons 16-18 to indicate his answer, whereupon play-back operation is resumed and the count, representing the time taken to answer the question, is recorded; the correct answer signal C and the time interval signal E are then scanned and fed to circuits for comparison with the respective student-derived signals. Depending on the result of these comparisons one or other of the lamps 19, 20, or an acoustic indicator, is energized to indicate a correct answer or an incorrect answer, and another indicator (not shown) is energized to indicate whether or not the student answered the question in the time limit determined by the signal E.

In a coin-freed vending machine, insertion of a coin of one denomination into a corresponding one of a plurality of coin-receiving members operates a switch to move a drive means to record the number of insertions into that member, and electric circuit means effecting carry over from the drive means of one denomination to the drive means of the next, and controlling ticket issuing apparatus. In Fig. 3, insertion of a penny energizes a corresponding solenoid 11, to advance wheel 15 one tooth. A disc 18 secured to the wheel has notches 25, at six-tooth intervals, so that when six pennies have been inserted, a micro switch operator 28 effects advancement of a sixpence wheel by one tooth. Equally, advancement of the sixpence wheel by five teeth (by insertion of sixpences or carry over from pennies) result in advancement of a 2/6d. wheel by one tooth. Discs 19 have similarly spaced recesses 26, and each is angularly preset relative to its wheel 15 to determine the price of a ticket, which is issued when each disc 19 is in a position to operate an associated microswitch by any one of its notches 26.

Abstract: 1406829 Bandwidth compression, facsimile system FUJI XEROX CO Ltd 10 Nov 1972 [11 Nov 1971] 52149/72 Headings H4R and H4F Bandwidth of an analogue signal, particularly a facsimile signal, is reduced for transmission by detecting each signal maximum above, or each signal minimum below, a predetermined reference value to divide the signal into consecutive time segments, each alternate time segment between successive maxima, or minima, is then inverted about an axis defined by the signal level at the time of inversion. Preferably the periods of inversion are signalled to the receiver by keying on a tone signal to enable regeneration of the original signal. As shown in Fig. 1, the signal applied to input 1 is fed to an adder 12 through either a direct channel, controlled by gate 9, or a channel containing inverter 11, controlled by gate 10. The selection of gate 9 or gate 10 is controlled by the antiphase outputs of bi-stable 8 which is triggered when both inputs to gate 7 are true. Gate 7 is fed by pulses e 3  generated whenever the input signal attains a negative maximum value and by a signal e 2  which is true whenever the input signal is below a predetermined signal level, e.g. "0" volts. Gate 7 therefore generates a pulse on each negative peak, and the bi-stable is set by every second pulse and reset by the intervening pulses. Circuit 6 is operated by the bi-stable 8 to hold the value of the negative peak through each period that the output e<SP>1</SP> 5  is true, and feeds that value to the inverter 11  as a reference about which value the signal voltage is inverted. Signal e<SP>1</SP> 5  is also used to enable oscillator 14 to generate a tone signal which is mixed with the filtered output of adder 12 to indicate when the signal has been inverted. At the receiver, Fig. 3, the tone signal is separated by high pass filter 21 and shaped to energize a bi-stable 23 which energizes gate 28 whenever an inverted signal is received, and gate 27 the remainder of the time. The analogue signal is applied to the gates 27 and 28 via the low pass filter 20 and the gate outputs feed adder 30, gate 27 direct, and gate 28 via inverter 29. The reference level for the inverter 29 is derived from the low pass filter 20 output via a hold circuit 26 operated by the "invert" output e<SP>1</SP> 18  of bi-stable 23.
