Title: Improvements in or relating to load-discriminating arrangements for electric circuit-breakers in three-wire systems
IPC: H02H11/00
Filed: 1926-12-04
Abstract: 286,369. Reyrolle & Co., Ltd., A.. and Willoughby, R. Dec. 4, 1926. Protective arrangements. - In a three-wire system comprising two outer conductors and a neutral, the circuit-breakers between the supply and the load cannot be reclosed when there exists an excessive balanced load across the outers or an excessive (unbalanced) load on the neutral, both excess conditions being provided for together. In the arrangement shown in Fig. 1, the mid-point of a battery G is connected to the neutral A through the coil D of a relay D<1> with its contacts in the circuit of the closing coil H of the circuit-breaker C<1>, C<2> energized from the outers. The ends of the divided battery are connected through assisting coils F<1>, F<2> and' through back contacts H<1>, H<2> of the circuit breaker (opened when the circuit-breaker closes) to the respective outers on the load side of the circuit-breaker. The coil D carries a current proportional to unbalanced load on the neutral and the coils F<1>, F<2> a current proportional to the balanced load on the outers. When either of these test currents is excessive one or other of the relays opens its contacts and the electromagnetic closure of the circuit-breaker is prevented or the circuit-breakers are locked open. As the auxiliary source a tapped resistance across the outers may be used or, in the case of an A.C. supply, a transformer with its primary across the outers and with a divided secondary. Where the load to be tested before connection is made may already be supplied from another source the arrangement shown in Fig. 5 is used. The circuit-breaker contacts in the outers are bridged by equal high resistances P<1>, P<2> the midpoints (or other corresponding points) of which are connected through the coil of a voltage relay 0 and a resistance O<1> in series, the mid-point ohmically of the two being connected through the relay N to the neutral. The relay N prevents closure of the circuit-breaker with an unbalanced load and the relay 0 with a balanced overload.

Title: Signal-modifying apparatus for a color-television receiver
IPC: H04N11/14
Filed: 1954-02-02
Abstract: 772,792. Colour television. HAZELTINE, CORPORATION. Feb. 2, 1954 [Feb. 26, 1953] No. 30837/55. Divided out of 772,791. Class 40 (3). In a colour television receiver, an asymmetrically modulated chrominance sub-carrier signal is modified to a symmetrical form suitable for application to a display, such as a singlegun, shadow mask, cathode-ray tube. The principle of the invention is illustrated in Fig. 2 with reference to a sub-carrier bearing quadrature modulations as shown in Fig. 2a. Y is the luminous component and equals .67G+30R+.03B. Such a sub-carrier may be resolved into the primary colour components as shown in Fig. 2c. The desired symmetrical form of sub-carrier is shown in Fig. 2b. To achieve the modification the original sub-carrier is combined with another sub-carrier of one-third the amplitude and appropriate phase but having the components in opposite sequence as shown in Fig. 2d. The combined signal is then as shown in Fig. 2c and by appropriate phase and amplitude adjustment is brought to the desired form in Fig. 2b. The second sub-carrier in Fig. 2d is generated from the original by heterodyning with a signal of double the sub-carrier frequency and utilizing the beat signal at the subcarrier frequency. In one way of carrying out the invention, Fig. 1, the 3.5 Mc/s. chrominance sub-carrier is selected from the output of the detector 14 by band-pass filter 61 and applied to a synchronous modulator 52. The modulator also receives a 7.0 Mc/s. signal from the synchronized colour-wave generator 33 through harmonic amplifier 45. Circuit 47 introduces a delay of 166‹ and potentiometer 48 is set to produce a beat signal of one-third amplitude. The beat signal then adds to the original subcarrier in the modulator and the modified signal appears at the output 30. In addition to modifying the sub-carrier it is also necessary to modify the luminance signal and this is effected as described in Specification 772,791 by means of circuits 31, 32, 40 and 41. The modified chrominance and luminance signals are then combined in adder 28 and applied to the cathode-ray tube 16. In a modification, Fig. 4 (not shown), the luminance and chrominance signals pass through a common channel. This is effected by omitting filter 61 from the input to modulator 52, so allowing the whole video band to enter the modulator, and following the modulator with a filter having an amplitude response characteristic arranged to establish the correct amplitude relationship between the modified sub-carrier and luminance signal. The correction for the luminance signal is effected in a separate channel as described in Specification 772,791. Specification 689,356 also is referred to.

Abstract: 211,237. Freeman, E. H. Nov. 21, 1922. Integrating; modifying scale of integrations.- An electric meter for registering the flow of a fluid comprises an induction motor meter having driving and braking torques with compensation for variations in voltage and frequency and corrections for differences in liquid pressure temperature and specific gravity. The meter comprises magnet cores 2, 3, 6, the flux across the disc 1 emanating from the core 6 being relatively small. Resistances 10, 11 connected in series provide for corrections in fluid pressure on either side of the orifice 16 and vary in conjunction directly with the velocity of the fluid through the orifice. Connected in parallel with the resistance 10 is a high inductance 9 and a resistance 8, the latter increasing with increases of fluid pressure,. The meter coil 7 is joined across the resistance 8 and and the inductane 9 is highly reative the voltage applied to the coil 7 will vary inversely as the frequency. The current in this coil also varies directly as the voltage applied and inversely as the frequency, and the flux produced varies inverselv as the square of the frequency. The flux due to the coils 4, 5, which have a high reactance, relative to the resistance 14 in series therewith, varies inversely as the frequncy, so that the speed of the disc is compensated for frequency changes. The resistance 14 corrects for changes in temperature of the fluid, and the movable contact c may vary the resistance 10 with changes in liquid densities.
