Cash registers.-The setting-levers 295 - - 298, such as those used in the machine described in Specification 181,072 for recording transactions &c. by perforating a paper strip, are stopped in the desired position by first depressing the necessary one of a series of plunger keys 375. This action slides longitudinally a notched bar 379, Fig. 3, by means of a pin and inclined slot 378, thus carrying its notches 385 out of alignment with the setting levers. Consequently when any one of these levers is moved, either up or down, a, pawl 391 carried by it engages with an unnotched portion of the bar and being limited in swing by either of two pins 384, 390 causes the lever to stop. An interlock between levers of the same order, for instance the levers 295 referring to the classes of goods, consists of a series of crowding pawls adapted when pushed aside by the passage of a setting-lever to engage notches in and so lock the remaining levers. Movement of any lever after the machine has started is prevented by a cam 289 which rocks arms 328 to compress springs 326 against the detent-pawls 325.

Abstract: 982,022. Testing bi-directiorial repeaters. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 24, 1961 [May 26, 1960], No. 18715/60. Heading H4L. Relates to an apparatus for effecting supervisory loop testing of the gain or loss of a telecommunication system up to and including one or more bi-directional repeaters incorporated therein, each being provided with a supervisory device capable of selecting, at the repeater output, a signal or signals transmitted in an outward transmission band and changing the frequency or frequencies of the signal or signals (e.g. by doubling) into signals for return transmission in an opposite going band, the corresponding outward and return paths constituting the loop to be tested. The apparatus comprises at least one sending apparatus 1 which includes a reference frequency oscillator TG1, a variable frequency oscillator TG2 and a modulator M1 fed by the two oscillators and arranged to provide a beat signal for transmission through the system; a carrier generating device 41 for producing an automatic tuning signal having a frequency equal to the reference frequency plus or minus the frequency of the signal returned from the repeater; a receiving apparatus 21 including a modulator M2 arranged to receive as inputs the automatic tuning signal and the returned signal from the supervisory device, whereby the frequency of the receiver modulator output is equal to the reference frequency despite variation of the frequency of the variable oscillator; and means including the meter G2 arranged to indicate the level of the signal output from the receiver modulator. In the embodiment described, the supervisory circuit 55 in the repeater carries out a doubling operation, so that the signal applied to the receiving apparatus is 2(# 2  - # 1 ) where # 2  is the variable frequency and # 1  the reference frequency produced at the transmitter. The automatic tuning signal required is thus # 1 +2(# 2 -# 1 ) = 2# 2  - f 1 , which may be produced in the carrier generator 41 by combining the signals # 2  and (# 2 -# 1 ) in the modulator M3 and separating the sum by means of a filter F3. The transmitting apparatus contains in addition to the components mentioned above a low-pass filter F1 (tuned to say 1220 kc(s.), level adjusting circuits 5 and cathode followers A1 to A4. The receiver contains further level adjusting circuits 25 and a preamplifier A5, a band-pass filter F2 tuned to the frequency # 1  (1304 kc.) and an amplifier A6. The output on the meter G2 will give a measure of the attenuation occurring through the system when set for any frequency in the range # 2 - # 1  (0-1220 kc(s.).
