Filed: 1961-01-17
Abstract: 1,017,281. Electronic counters. ROTAX Ltd. Feb. 7 1961 [Jan. 17 1961] No. 1853/61. Heading G4A. [Also in Division H2] The thyristors of an inverter (see Division H2) are fired by pulses from a ring of six counterdriven by a square wave oscillator having transistors 51, 52 fed from a supply stabilized by a Zener diode. The oscillator frequency is six times that of the inverter. Each stage of the ring comprises a series arrangement of resistor, ordinary diode, four layer diode and resistor connected across the oscillator output, and with coupling capacitors 65a, 65b ... 65f as shown. The oscillator output voltage is just insufficient to break down the four layer diodes. When one four layer diode, say 63a, is conducting the adjacent coupling capacitors 65f and 65a become charged, and as the oscillator output voltage becomes zero the preceding coupling capacitor 65f is discharged, but the following one, 65a, remains charged, and on the next rise of oscillator output voltage the capacitor voltage and the oscillator voltage are added, so breaking down diode 63b.

Abstract: 763,913. Sorting by gauging. PATENTUND VERSUCHSANSTALT. Jan. 24,1955 [Feb. 9, 1954], No. 2058/55. Class 106 (2). A method of testing specimens according to at least one of their parameters and subsequently sorting the specimens into their tolerance categories is characterized in that those specimens whose measured value lies near the boundary between two adjacent categories are allocated to an intermediate catagory having a given value range, all the test specimens which fall into such intermediate categories being conveyed to a common point preferably thereafter being resorted. As shown in Fig. 2 a sliding contact 3 is moved over spaced fixed contacts A-F representing the various catagories into which the parameter indicated by the movement of contact 3 may fall and each contact controls a circuit effecting the pivoting of an associated gate 8a-8f in the grading unit 9. Articles falling clearly within a particular category are thereby discharged through the associated shoot SA-SF but where the parameter measured lies between two such categories, not only are the gates for both categories pivoted but also an "intermediate category gate " 8z is operated by means of a controller 10 responsive to the completion of any two category circuits and any such article is thereby discharged into shoot SZ. In another embodiment associated with the linear dimension gauging means of Specification 760,384 the contacts A-F are spaced apart by insulated zones equal in range to the inter. mediate range between categories so that no gate is operated to divert articles of the intermediate categories which consequently fall through a discharge shoot at the end of the grading unit.

Abstract: 985,542. Automatic exchange systems. R. MAUDUECH, R. GOUTTEBEL, and L. PROUTIERE. Jan. 21, 1963 [Jan. 26, 1962; Nov. 20, 1962], No. 2552/63. Heading H4K. A subscriber's line circuit includes a source of illumination and a photo-sensitive device which are so connected that looping of the subscriber's line causes said source to illuminate said device and thereby lower its resistance.. The invention is applied to a remote concentrator which is connected over a 4-wire highway to a T.D.M. exchange which utilizes pulse code modulation. As shown, the concentrator 200 comprises outgoing and incoming amplifiers 210, 220, an exchange signalling amplifier 240, a decoding matrix 230 which has an outlet in respect of every line connected to the concentrator and which serves, when suitably signalled from the exchange, to provide sampling pulses to the relevant line circuit and calling and ringing circuits 250, 260. A subscriber's line is tested by the application of a pulse from decoder 230 to the winding 181 of pulse distributer 180 during a time slot which is not in use for a call. Consequently, if the line 101 is looped whereby neon lamp 121 is illuminated, photo-conductive diode 122 has a low resistance and the pulse is passed to the amplifier 240 which thereby informs the exchange that the subscriber is calling. A time slot is then allotted to this subscriber and the pulse from decoder 230 produced during this time slot is then used to test the condition of the line during the subsequent dialling, talking and release periods in addition to unblocking the (pulse amplitude) diode modulator 140, 141 and transistor demodulator 150. In order to ring a subscriber, " calling " pulses are applied to the amplifiers 250, 220 at the same time as the decoding matrix is signalled from the exchange. Consequently, capacitor 192 in shunt with read relay 193 is charged up and thus eventually causes the relay to operate and thereby connect ringing generator 260 to the line. The Specification discusses the effect of capacitor 151 and 157 on the switching characteristics of the transistor 150 with reference to Fig. 3 (not shown). An alternative form of modulator using back-to-back diodes and a simplified pulse distributer are depicted in Fig. 1 (not shown). The pulse amplitude modulation derived from modulator 140, 141 is converted into pulse code modulation in the concentrator 200 before transmission to the central exchange.
