Title: Improvements in or relating to indicating systems for electrical signals, particularly for use with radio beacons
IPC: G01S1/02
Filed: 1946-04-15
Abstract: 610,954. Current-direction indicators. DECCA RECORD CO., Ltd., and O'BRIEN, W. J. April 15, 1946, No. 11556. [Class 37] [Also in Group XL (c)] An arrangement for ascertaining the polarity of the maximum peak of an alternating potential of asymmetric waveform comprises a pair of halfwave rectifiers which rectify separately the alternating potential and its image, a load resistance connected to each of the rectifiers, and a low-resistance centre zero galvanometer connected between the load sides of the rectifiers. The arrangement is described for use in the receiver of an aircraft flying towards a beacon of the overlapping- beam type, in which the two sides of the course-line are characterized by dots and dashes respectively. The received radio signals such as 49, Fig. 3 (corresponding to a preponderance of dots over dashes) are heterodyned at 12 and rectified at 29, 31 to produce the pulsating direct-current wave 50, Fig. 3, across load resistance 33. This wave is passed through filter 35, 38 to resistance 34 and the direct-current component of the voltage across this resistance is removed by condenser 40 so that the wave-form impressed on the primary of auto-transformer 39 is of the form shown at 51, Fig. 3, and the wave-form existing at the other end of the winding is the image of this (53, Fig. 4). These two voltages are impressed on the half-wave rectifiers 42, 43, provided with load resistances 44, 45, shunted by smoothing condensers 46, 47. The galvanometer 48 is connected across the loads as shown. That rectifier which is fed with the wave having the larger positive peak value conducts and produces a voltage as indicated at 54, .Fig. 4, across its associated load circuit and also blocks the other rectifier owing to the low resistance of the galvanometer. The galvanometer thus deflects to the right or the left in dependence upon the relative amplitudes of the dots and dashes.

Abstract: 166,739. Knowlton, J. A. April 28, 1920. Tidal energy, utilizing.-Relates to apparatus of the kind in which the rise and fall of the tide is utilized to compress air for driving machinery. A basin 11, Fig. 1, is separated from the tidal water 10 by means of a. dam 12 provided with sluces 13, 14. Within the basin 11 is built a walled enclosure 15, at one side of which is a sluiceway 16 communicating with the basin 11 and also with the tidal water 10 when the sluice 13 is opened. Within the walled enclosure is a spillway 17 and two basins 18, 19 closed at the top. On the top of these basins are mounted the turbines and control apparatus. The basins are connected through inlet and outlet air pipes 72, 74, Figs. 5 and 6, provided with non-return valves 73, 75 to turbines 34. Compartments 36, Figs. 3 and 5, and 37, Fig. 3, are provided communicating with the basin 11 and spillway 17 respectively and also with the chambers 18, 19 by means of passages provided with gates 47, 48. The gates are mounted on racks 52 and connected in pairs by links 58 so that when one gate is opened the other is closed. The gates are operated by means of electric motors 56a, 56<d> which are controlled by means of floats 42, 25, Fig. 6, mounted in wells 20, 21 communicating with the basins 18, 19. The floats normally rest on stops 26, but when raised by the inflow of water close the electric contacts 67, 70. The motors are electrically connected to operate in pairs so that when one chamber is open to the basin 11 and closed to spillway 17, the other is-open to the spillway and closed to the basin. In operation, the basin 11 is filled with tidal water through the sluiceway 13 and the spillway 17 left empty. Water is admitted alternately to the chambers 18, 19 compressing the air and forcing it through the pipe 74 to the one of the turbines and thence through the pipe 71 to the other chamber. The sluices 13, 14 are operated from time to time so as to obtain a difference in head between the basin 11 and spillway 17 and to empty the spillway to the sea at low tide. When it is desired to stop the apparatus, the sluices 39, 40, Fig. 3, are closed.

Title: Magnetic amplifier circuit
IPC: H02H3/04
Filed: 1964-03-20
Abstract: 1,054,289. Magnetic amplifiers. STANDARD TELEPHONES & CABLES Ltd. March 20, 1964 [March 26, 1963], No. 11854/64. Headings H3B and H3T. In a magnetic amplifier circuit comprising two rectangular hysteresis cores, when the D.C. input current applied to two series connected D.C. windings, one on each core, exceeds a predetermined level a third magnetic core is switched from one saturated condition to the other by current passing through a winding wound on the third core in series with an A.C. voltage supply and two A.C. windings wound in series opposition, one on each of the first two cores. The circuit is as shown in Fig. 1, and the current in the A.C. windings na due to the A.C. voltage supply Va is rectangular, Figs. 8 (a), 8 (b) (not shown), each half-cycle having two levels Io, Ia due to cores A and B changing their saturation state. Since the A.C. current amplitude ia is linearly proportional to the D.C. current Ic a surge current Ics is detected by utilizing the flux charge in core C produced by current ia flowing through winding ni proportional to the surge current Ics. The number of turns of winding ni are such that for a given value of D.C. surge current the flux in core C is switched completely and the resulting negative voltage pulse induced in winding nb triggers transistor T 1  into conduction. In the arrangement of Fig. 2 (not shown), the winding nb is constituted by two parts connected in series, the connection point being grounded, and two diodes are connected between the opposite ends of the windings and the base of the transistor. Thus when a D.C. surge current occurs the transistor will be operated twice per cycle of the A.C. current instead of once per cycle as in Fig. 1. Alternatively, two transistors T 1 , T 2  may be employed, Fig. 3, one transistor conducting during each halfcycle. The circuits of Figs. 1 and 3 may be modified to form a conventional blocking oscillator circuit by the inclusion of a collector winding, Figs. 4 and 5 (not shown). The circuits may be used in a system for the protection of DC power supplies in a bay of D.C. power distribution for electronic equipment, Fig. 9 (not shown).
