Abstract: 612,841. Integrating-apparatus. LANDIS & GYR SOC. ANON. May 6, 1946, No. 13739. Convention date, May 5, 1945. [Class 106 (iv)] [Also in Group XX] Apparatus for integrating the product of two variables comprises two pairs of discs, one of each pair being fixed and one movable relative to the first in accordance with a variable, and means, driven by a constant speed motor through clutch means, for scanning the first pair of discs so as to transmit a proportion of the rotary movement of the motor in accordance with the first variable to similar clutch and scanning means so that a further proportion of a rotary movement according to the second variable is transmitted to counting mechanism. As applied to a heating system, a motor 1 drives a gear-wheel 4 at constant speed and a pawl 10 fixed to a freely mounted shaft 8 drives a gear-wheel 12 for a fraction of each revolution of the gear-wheel 4 as determined by the. angular displacement from a fixed cam disc 14 of a cam disc 15 moved by rack 24 and pinion 18 in accordance with the rate of flow of the heating fluid. The gearwheel 12 drives a counter to register the aggregate flow and drives through a chain of gears a gear-wheel 27 which by a similar process drives a gear-wheel 28 for a fraction of each of its revolutions determined by the temperature difference of outward and return flow of heating fluid obtained through differential gearing 32. The gear-wheel 28 thus drives a counter 39 to register the aggregate over a period of time of the products of the flow and temperature difference for each revolution of the wheel 4 during the period. In a modification applied to flow meters, particularly for steam, a correction is applied for variations in pressure and temperature through the differential gearing 32 by actuating one of the racks 37 by means responsive to pressure and the other by means responsive to temperature.

Abstract: 1,098,016. Automatic frequency control systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 31, 1966 [April 3, 1965], No. 14257/66. Heading H3A. A relaxation oscillator used for the frame scan of a television receiver is synchronized by an automatic phase control loop and also by the direct application of synchronization pulses through a capacitor to a control electrode of a valve or transistor in the oscillator, the pulses being of such height and width that the frequency-increasing effect of the direct synchronization is compensated by the frequencyreducing effect of charge flowing from the control electrode to accumulate on the capacitor. In Fig. 3 line and frame pulses on input terminal 30 are integrated by networks 28 and 29, amplified and limited by transistor 34, and integrated again by networks 37 and 42 to provide the direct synchronization pulses applied to the valve 15 forming part of the oscillator. An output from the oscillator via winding 45 is differentiated and applied to the diode 41 in a sense to add to the input to the diode from transistor 34, so that the diode acts as a phase discriminator and provides a second input to the valve 15. A further output from the oscillator is taken from winding 19 and differentiated by network 51 before being applied in a subtractive sense to the collector of transistor 34, thereby reducing the width of the output pulse 36 and so reducing its frequencyreducing effect. In modifications, Figs. 1 and 5 (not shown), the oscillator is a blocking oscillator using a single valve or transistor.
