Abstract: 924,574. Automatic exchange systems. SIEMENS & HALSKE A.G. Dec. 29, 1960 [Dec. 29, 1959], No. 44681/60. Class 40 (4). Arrival of a digital signal, which may be in multi-frequency code, on the trunk ga causes a receiver M2 to be associated with the trunk. The receiver decodes the signal and stores the information in a register S individual to the trunk ga, whereafter the receiver M2 is released. On receipt of a second digit a receiver M2 and and a marker M1 are associated: M2 decodes the signal and passes the information to M1 via line 12. The information stored in the register S is also passed to M1 which then controls the setting of the selectors GW and TW in accordance with the two digital signals received. The marker M1 may also control the selector TW to connect a calling subscriber T to a free link ta.

Abstract: 1,174,064. Automatic phase control systems; television. BRITISH BROADCASTING CORP. 16 Aug., 1967 [12 Oct., 1966], No. 45588/66. Headings H3A and H4F. Apparatus for synchronizing a first television signal (e.g. from Eurovision) in field frequency and phase with a second television signal (e.g. a local signal) of the same nominal field frequency, comprises a variable delay device controlled by a comparison of the synch. signals. In Fig. 1 the input signal at terminal 10 passes through an interpolator 11 to a delay line 12 comprising delay sections D1-Dn controlled by associated cross-over switches S1-Sn and having delays which vary in binary steps from half a picture period down to about 2 microseconds; this is followed by a similar fine delay unit 13 having delays varying from 2 microseconds down to about <SP>1</SP>/ 10  of a picture unit (say 10 ns.), both delay lines being controlled by comparison of the synch. signals in respective units 14 and 17. When a picture has to be omitted or repeated at intervals, due to different actual field frequencies, the interpolator may comprise a delay unit of one picture period (21, Fig. 2, not shown), the instantaneous and the delayed signals being fed to two output addition units (22, 23) in proportions determined by a waveform generator (24) controlled by the synch. signals. For the case where a field has to be omitted or repeated the coarse store is modified so that the longest delay section is ¢ field instead of ¢ picture. In this case one of two other types of interpolator may be used. In one, Fig. 3 (not shown), the input signal is applied directly to one output addition unit (27) and through a one line delay (25) to a second output addition unit (28). A second input to both output units is provided by a FIELD-¢ LINE DELAY (26) fed from the one line delay (25). The other interpolator, Fig. 4 (not shown), comprises two weighted addition units (31, 32) receiving as inputs the instantaneous input signal and the same signal delayed by one line.

[Also in Division G1] Relates to a check weigher for checking the deviation in the weight of an article from a desired value, by determining the period of oscillation, using pulse counting circuitry, of a resiliently supported weigh platform due to an article thereon. In Fig. 2 a weigh platform 12 is carried by a vertical spindle 6 resiliently supported by crossed leaf springs 10. In operation a projection 15 of the spindle is forced against an upper limit stop 8a by a pneumatic actuator cylinder 16. An article is placed on the platform, air is released from the cylinder allowing the spindle to drop against the restraint of the springs 10. The spindle oscillates vertically and a voltage output will be produced by a coil 17 attached thereto, moving in the field of magnets 18. The voltage will be zero at the upper and lower limits of movement and the interval of time between successive zero outputs showing the same polarity change sense is equal to the period of oscillation T1 of the platform. The relationship between a known mass M2, having a period T2, and the unknown mass M1 is given by The period of oscillation may be measured by utilizing the output of the coil to open a gate circuit (not shown) which then admits pulses of high constant frequency to a pulse counting circuit. The input gate is arranged to open at the first desired signal output voltage and close at the second. The interval between the gate operations is thus equal to one period T1. The pulse frequency may be controlled by a crystal oscillator.

Abstract: 1522327 Semiconductor devices ENERGY CONVERSION DEVICES Inc 13 Nov 1975 [14 Nov 1974] 46917/75 Heading H1K [Also in Division H3] A transistor-like device of which either the emitter region 4 (Fig. 1) or the collector region 8<SP>1</SP> (Fig. 5) is of a material which switches from a high resistance to a low resistance state on application thereacross of a voltage above a threshold value, is operated with selectively applicable emitter-base and emitter-collector biases, the latter of which is on its own insufficient to cause the switch material to become conductive but the joint application of both of which causes the material to switch. In the non-conductive condition of the switch material a negligible emitter-collector current flows, whereas when the switch material is conductive a maximum emitter-collector current flows. If, after simultaneous application of both biases, the emitter-base bias alone is removed a significant emitter-collector current, generally of an intermediate value less than the maximum value referred to above, continues to flow, and this provides a logic circuit in which three distinct conditions may be detected. In the circuit of Fig. 5 these are detected by directly sensing the level of the collector current using two amplitude level sensing means, such as Schmidt trigger circuits, 40<SP>1</SP>, 42<SP>1</SP>, set to trigger respectively at the intermediate and maximum collector current levels. The outputs of circuits 40<SP>1</SP>, 42<SP>1</SP> are coupled to binary logic circuit 44 in turn coupled to indicating means 46. In the circuit of Fig. 1 level sensing means 40, 42 are set to detect the presence or absence of collector and base currents respectively, and the outputs thereof supply a binary logic circuit 44 to provide indication of the same three logic states as in the previous embodiment. Constructionally, the switch material 4 or 8<SP>1</SP> is preferably r.f.-sputtered on to a Si body containing the other two device regions, e.g. formed by epitaxy. The switch material may be of either "threshold" or "memory" types, and several suitable materials are disclosed. Reset mechanisms appropriate to the particular type of switch material are employed (i.e. simple interruption of the emitter-collector current for a "threshold" material, and application of a reset current pulse for a "memory" material).
