Abstract: 1,010,605. Automatic frequency control. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. June 12, 1962 [June 9, 1961; Sept. 22, 1961 (2)], No. 22433/62. Heading H3A. A television receiver circuit for synchronizing a local oscillator from which the line time base is derived, with a received synchronizing pulse train comprises a pair of rectifiers 7, 6, to an anode and cathode, respectively, of which positive and negative synchronizing pulses are applied via transformer 3 and capacitors 4, 5 and a differentiating circuit including capacitor 21 and resistors 22, 23 connected to the common junction 8 of the rectifiers. A train of pulses 9 derived from the line time base circuit is applied to the differentiating circuit and an output signal which is a function of the difference in frequency between this train and the synchronizing pulse train is obtained across capacitor 18 and applied to reactance valve 17 to control the local oscillator. In order to obtain a relationship between the output signal and the frequency difference which is symmetrical about the synchronized condition a pulse 20 also derived from the line time base circuit is added to each derived pair of differentiated pulses in order to increase the amplitude of the second pulse.

Title: Improvements in or relating to nuclear reactor coolant systems
Inventor: SCHLUDERBERG DONALD CARROLL
IPC: G21D3/08
Filed: 1961-06-21
Abstract: 936,518. Cooling reactors. BABCOX & WILCOX CO. June 21, 1961 [June 21, 1960], No. 22461/61 Class 39 (4). The coolant gas of a nuclear reactor contains solid particles, the concentration of which is automatically varied to maintain the coolant temperature constant at the reactor pressure vessel. The temperature monitoring device at the reactor operates valves and pump motor controllers to adjust the relative proportions of the constituents in the coolant. The gas may be carbon dioxide, nitrogen, air, helium, neon or argon and the particles may be graphite, lamp black, oxides or carbides of aluminium, beryllium or zirconium. As shown, coolant gas is circulated through the reactor 12 and heatexchanger 14 by the pump 16. A change in load at 14 is reflected in a change in temperature across 12 which causes the control device 45 to operate, through the control system 44, on the valves 24, 26 and pumps 38, 43. An increase in load on 14 causes an injection of solid particles into the coolant circuit from storage vessel 28 which simultaneously receives an equal volume of the original coolant mixture from the circuit. A decrease in load causes coolant to flow into separator 21 of vessel 28 where the solid material is retained and the gas then returned to the cooling circuit. The amount of solid in the vessel 28 may be adjusted by the external system 50.

Abstract: 746,152. Fluid-pressure brakes. WESTING- HOUSE AIR BRAKE CO. Aug. 9, 1954 [Sept. 11, 1953], No. 23060/54. Class 103 (1). A triple valve for fluid pressure railway braking apparatus, connected to a brake pipe 2, supply reservoir 3 and brake cylinder 4 and having a service selector valve 6, graduating control device 7, brake cylinder inshot valve device 8, control reservoir cut-off valve device 9, quick service control valve device 10 and supply and control reservoir release valve device 11, is characterized mainly in that initial charging of the reservoir 3 from the brake pipe 2 occurs by way of one choke passage 184 which prevents overcharge of the reservoir to any appreciable extent during the time the brake pipe 2 may be overcharged at full main reservoir pressure, and an additional choke passage 500 combined with a check valve 501 is brought into action when an overcharge in the reservoir 3 is dissipated to the brake pipe when pressure therein is reduced to its full normal value. The size of the combined choke passages is made such that dissipation is sufficiently rapid to prevent an overcharge great enough to cause application of the brakes by an undesired operation of the quick service valve device 10, but not so great as to prevent a rapid drop in brake pipe pressure relative to supply reservoir pressure, to be brought about for initiating a brake application. During initial charging of the supply reservoir 3, the brake controlling valve device 7 will limit the pressure in passage 95 below the spring loaded recharge check valve 90 to prevent any charging of the supply reservoir via passages 60, 96, 60a, 26 and 27. Specification 702,100 is referred to.

Filed: 1948-09-03
Abstract: 649,312. Code telegraphy. STANDARD TELEPHONES & CABLES, Ltd. Sept. 3, 1948, No. 23224. [Class 40 (iii)] [Also in Group XL (c)] In order to avoid distortion in a carrier frequency telegraph system when the signalling frequency approaches the carrier frequency, the leading and trailing edges of the signal pulses are rounded and are fed to a modulator which has a linear response characteristic over a limited range but is driven beyond that range by the pulses. As shown, the initial pulse signals a, Fig. 3, are fed to a shaping network 8, 9, Fig. 1, or to a low pass filter, to give the pulses the shape shown at b, Fig. 2. The pulses and the carrier from the source 5 are fed to a modulator 4 which if operated in its linear range would produce carrier pulses shaped as at c, Fig. 3. The modulator, however, is operated much beyond its linear range, thus producing the carrier pulses d, Fig. 3. The signals may be transmitted as phase reversals of the carrier. They may alternatively be transmitted as shifts of the carrier frequency ; for this purpose the frequency modulator may be of the kind described in Specification 617,139, [Group XL (c)], and the signals used to overdrive the auxiliary amplitude modulator employed in that system. The carrier frequency is described as being in the audible range, and multiplexing by the use of different audio frequencies is referred to.

Title: Improvements in control mechanism for electric ship propulsion and like systems
IPC: B63H23/24
Filed: 1922-08-28
Abstract: 185,409. Metropolitan - Vickers Electrical Co., Ltd., (Assignees of MacNeill, J. B., Bakken, A. H., and Tucker, C. A.). Sept. 1, 1921, [Convention date]. Dynamos and motors combined for transmitting power. - Installations comprising turbines, dynamo - electric generators, and motors, for ship-propulsion and other purposes in which the control switches are operated by a number of separate handlevers, are provided with groups of mechanical interlocks to prevent incorrect sequence in manipulating the levers for starting, speed control, stopping, reversing, &c. Generator field switch levers are locked by fluid pressure in cylinders communicating with turbine speed controllers, in order to prevent the opening of the field switches if the turbines are running above a certain speed. The invention is described in connection with an installation arranged as shown in Fig. 4, and comprising two turbine-driven generators 1, 2 and four motors 3, 4 driving four screw propellers. The control gear consists of generator field-switches 5, 6, motor pole-changing switches 9, 10 corresponding respectively to 36-pole and 24-pole motor fields, forward and reverse switches 11<a>, 11<b>, liquid rheostats 12 operated by valves 12<a>, motor-secondary switches 13, separate generator circuit-breakers 14, 15, and circuit-breakers 16 for tying all the motors to one generator when required. Figs. 1 and 1<a> show the disposition of the hand-levers and interlocks for two motors normally fed by separate generators, black rectangles representing the levers in their open positions. A group of interlocks shown in Fig. 1, consisting of a number of bent levers 27, 38, rocked by longitudinal movements of bars 24, 37, ensure that the generator field switch hand-levers 88, 89 are closed after the reversing and pole-changing levers, and before the rhecstat valve and motor-secondary levers. The bars 24, 37 are disposed as shown in Fig. 2 to work separately while the motors are being fed from different generators, but are locked together when all the motors are thrown on the same generator. A second group of interlocks, shown in Fig. 1<a>, consisting of a number of longitudinally slidable rods 132, 133, the extremities of which are adapted to move into and out of the paths of the switch hand-levers, ensure that the generator circuit-breakers, the pole-changing switches, and the reversing switches are closed successively. Interlocks of the second group also prevent the generators from being accidentally paralleled when the tying circuit-breakers are closed. After the generator field switches have been closed, the hand-levers are permitted by a lost-motion device, irrespective of interlocks, to be moved back far enough to insert resistance for accelerating. The Specification fully describes the interlocking functions in the sequences of operations for starting, running up to full speed on the initial pole setting, changing to economical pole setting, reversing, and stopping.
