Title: Improvements in or relating to switching matrices for time division multiplex telecommunication systems

Abstract: 1,034,924. Automatic exchange systems;. POSTMASTER GENERAL. June 1, 1962, No. 26177/64. Divided out of 1,034,921. Heading H4K. In a time division multiplex system comprising a co-ordinate array of cross-point switches for interconnecting incoming and outgoing multiplex trunks, each cross-point has an individual control circuit which under the influence of a set of (rectangular) pulses and a set of sawtooth pulses controls the closing and opening respectively of the switch during the relevant time slot. As shown, each trunk, comprising for example GO and RETURN highways 2, 3 together with their associated marking paths 1, 4, is multipled to a number of crosspoint switches, e.g. transistors 9 to 12 controlled by an individual circuit, e.g. NPN transistor 16. During the time slot allotted to a connection via the switch shown, a positive-going P pulse provided by circulating store 28 charges capacitor 23 so that eventually transistor 16 bottoms and thereby initiates conduction of the transistors 9 to 10 of the switch. The leading edge of each P pulse occurs when a sawtooth wave BP2 is at its minimum. Consequently, upon cessation of the P pulse, the rate at which capacitor 23 discharges into the base circuit of 16 is governed by the slope of BP2, the discharge terminating abruptly when BP2 reverses whereby transistor 16 and hence transistors 9 to 12 stop conducting.

Title: Square root measuring system
IPC: G06F7/552
Filed: 1969-05-22
Abstract: 1,274,019. Square root calculator. NIPPON COLUMBIA CO. Ltd. 22 May, 1969 [25 May, 1968], No. 26267/69. Heading G4A. The invention relates to a device for calculating square roots. The calculating procedure operates in accordance with the flow chart in Fig. 1 and is described with reference to part of an example shown in Table 1-1. A number such as 3 is entered into a register A, its digits are divided into pairs working from the decimal point and the number is shifted until the least significant half of the most significant pair is in the third most significant digit location, (as shown 03 is shifted until 3 is in location number 7 in a ten digit shift register with locations 0 to 9). A decimal point counter is incremented with each shift of the number so that the counter content indicates the location containing the least significant digit before the decimal point. Value α equal to the whole number portion of half the content of the counter and M equal to the location number of the least significant half of the most significant pair are calculated and stored in stores M, S. Step VI determining whether the contents of A are greater than the contents of a register B initially containing zero is performed and the subtraction of step V is performed. In step VI it is determined whether the contents of A are equal to or greater than the contents of B having a 1 added to the location defined by the number in 7. This incremented content of B is subtracted from A and the result stored in A and the incremented number stored in B. Step IV is performed again and the loop is followed until one of the comparisons step IV or step VI gives a NO result. If the comparison in step IV gives a NO then steps IX to XIII are followed. If MŒ0 the contents of A are left shifted one position, the value of α in store S is incremented by 1 if and only if M is odd and M is decremented by 1. The loop including steps IV to VII is then followed again until another comparison gives a NO answer. The process finally ceases when M = 0, the number in the B register being the required square root.

Title: Improvements in or relating to television systems
IPC: H04N5/16
Filed: 1934-09-14
Abstract: 428,661. Television. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Sept. 14, 1934, No. 26461. Convention date, Oct. 12, 1933. [Class 40 (iii)] In a television transmitter, the slow variations of the direct current component of the picture signals representing variations in the mean brightness value of the transmitted picture are utilized to modulate an auxiliary frequency which is separately transmitted as a modulation of an existing carrier which is also used for some other purpose in connection with the picture transmission. The additional carrier may be used to carry accompanying sound and/or synchronizing signals or may itself be a synchronizing frequency. Alternatively, the auxiliary frequency may be a sub-carrier carrying a synchronizing frequency. The auxiliary frequency may be varied automatically in amplitude or in frequency in dependence on the varying DC picture component. Fig. 1 shows a transmitting arrangement in which a moving film 1 is scanned by a Nipkow disc L and a supplementary photo cell 2, additional to that Z provided for developing the actual picture signals, is arranged to be activated by light reflected from the disc L, which reflected light is proportional to the average brightness over the whole picture area. The current output from cell 2 is fed to an amplifier 3 whose output controls the amplitude of an auxiliary oscillation frequency fed from f to the grid of a valve 4 upon which is superimposed the output from 3. The auxiliary frequency in the output circuit of valve 4 is applied to the modulation device 5 of a radio transmitter S transmitting the additional carrier and which is also modulated (by means not shown) with sound and/or synchronizing signals. Fig. 2 shows a co-operating receiver arrangement in which the apparatus 6 amplifies and demodulates the additional carrier wave, the auxiliary frequency being separated out from the resultant low frequency output from 6 by a filter 7 whose input terminals are in parallel with those of a circuit for using the sound and/or synchronizing modulation. As shown, this circuit comprises an amplifier NV and loud-speaker Lsp. The separated output from 7 is rectified at 8 and the resultant slowly varying direct currents are caused to build up potentials which are superimposed on the Wehnelt cylinder 9 of a cathode-ray tube picture reproducer 10 to which electrode are also supplied (by means not shown) picture signals derived from a picture signal receiver proper BE. If the rectifier 8 has a characteristic which deviates too far from the rectilinear, the resultant distortion in the reproduced picture may be avoided by introducing compensating opposite distortion at the transmitter.

Repeating and amplifying systems.-A highfrequency signalling system wherein two transmission lines extend to distant stations from a common station is so arranged that the two lines can be connected, the common station then serving for repeating from one line to the other. A plurality of carrier frequencies may be employed for multiplex working. The two main lines ML, ML<1> are balanced by artificial lines MN, MN<1>. The transmitting apparatus for the line ML comprises a telegraphic relay TR energized by signal currents and controlling the circuits of a valve oscillator G1. The oscillations are amplified by the valve TA1 the output circuit of which is inductively coupled to a line TL connected across the main line ML. The receiving-apparatus for the line ML comprises a transformer 10, amplifying-valves RA1 and a detector D, having a telegraphic relay RR in its output circuit. Similar transmitting and receiving apparatus are provided for the line ML<1>. When the apparatus is to be used as a through repeater from the line ML to the line ML<1>, a connexion is made through a switch S, from the output side of the receiving- amplifiers RA1 to the input side of the transmitting-amplifier TA<1>, and the generator G' is put out of action. A similar connexion through a switch S<1> enables the apparatus to act as a repeater from the line ML<1> to the line ML. The connexions S1, S<1> do not prevent signals being detected and recorded at the repeating station. Multiplex working is obtained by using different carrier frequencies, filters or tuned circuits TF1, RF1 being used in the transmitting and receiving circuits.
