Abstract: 1309079 Acoustic direction-Tenders EMI Ltd 16 June 1970 [16 July 1969] 35715/69 Heading H4D An acoustic detection system comprises means for generating first and second local signals proportional to the sine and cosine of the angle of rotation of a cardioid directional pattern means for deriving said pattern from the first and second local signals and signals derived from an acoustic source, means for producing analysis signals proportional to the square of the amplitude of the cardioid function, means for multiplying the analysis signals by the corresponding value of said first local signal and summing the product signals derived during at least one rotation. Co-situated transducers 1, 2, 3 have directional patterns 4, 5, 6 as shown and the signals received from source 7 are added after being multiplied in units 11, 12, 21 by signals Bsin #t, Bcos #t and B respectively, where # is rotation rate. This produces a directional pattern equivalent to a rotating cardioid and the direction, 0, of the source 7 is indicated by the phase of the adder 13 output with respect to Bsin #t. The signals U = Bcos #t and V = Bsin #t are produced in units 9, 10 and are quantized, #t changing by # every T F  seconds under the control of clock 19. For every step the adder 13 undergoes spectral analysis and a signal corresponding to the power content of the adder output is multiplied by U and V and the product stored in stores 17, 18. At the end of one revolution, the contents of the individual stores are added to reduce the noise level thus producing signals proportional to cos # and sin #. These are fed to a device 20, e.g. algoniometer which produces an output proportional to 0.

Abstract: 1330131 Control of D.C. motors CABLEFORM Ltd 16 Sept 1970 [23 Sept 1969 6 Feb 1970 7 Feb 1970 14 Feb 1970] 46727/69 5741/70 5990/70 and 7188/70 Heading H2J A series or shunt motor A is supplied from battery B through a thyristor switch S, while detector D provides a signal V1 representing the peak motor current, this signal being applied to an amplifier G which also receives a threshold signal VR corresponding to the current at which maximum design horse-power is reached. Until the signal V1 exceeds the signal VR, there is no output from the amplifier G so that the switch S is controlled entirely by a demand signal obtained from a control pedal. When the signal V1 exceeds the signal VR, the demand signal is modified by the output of amplifier G whereby the motor voltage decreases with increasing current. The degree of voltage reduction is determined by the gain of amplifier G which is set by adjustment of feedback H. Typical speed-current characteristics for shunt and series motors are described, Fig. 2 (not shown). A fuse FS in the battery circuit has a lower rating than the maximum motor current. Similar fuses may interconnect adjacent cells of the battery, Fig. 4 (not shown). A PTC thermistor TH responds to the temperature of the heat sink of the thyristors, the motor or other part to be protected. If the temperature exceeds a predetermined level, the demand signal is modified to reduce the current from the switch S. Alternatively, an output stage of the amplifier G contains the thermistor. If desired VR may be obtained from a plurality of thermistors sensing the temperature of various parts of the apparatus. Typical characteristics relating speed or duty cycle to current are discussed for a series motor, its supply battery and the thyristor switch operating at a constant recommended temperature, Fig. 3 (not shown).
