Auxiliary anodes H may be present. axis and then back towards the axis so that it passes through an aperture on the axis in the final lens plane, a stereoscopic effect is obtained by switching the first deflection alternately to opposite sides of the axis. The basic stereo switching signal is a square wave preferably at line scanning frequency, and this is fed directly to the synchronizing system 118 of the display system, as shown in Fig. 7. This signal is also fed to the line deflection amplifiers 114 and 116 via a correction circuit 100 which introduces corrections for the required stereo angle (from potentiometer 18) the accelerating voltage (f##) the focal length of the final lens (as represented by the current I L ) and for effecting correct registration (from potentiometer 28). The height of an image point relative to a datum point in the image may be determined by measuring the distances between the two points on both displays, the difference between the two distances corresponding to the height difference. The distances may be measured by adjusting brightup pulses to coincide with the points on the displays and using these to gate clock pulses, or alternatively measuring the time between them in analogue fashion. Signals from the microscope may be encoded with information as to the stereo channel which they represent and then recorded, to be subsequently decoded and gated to the respective channels of a display.

Abstract: 1,168,073. Signalling over power circuits. LONDEX Ltd., and LONDON ELECTRICITY BOARD. 22 Dec., 1966 [30 Dec., 1965], No. 55197/65. Heading H4R. In a system of signalling over power circuits the signal is conveyed by modifying the power circuit voltage, e.g. by connecting a discharged capacitor, or an oppositely charged capacitor to the power circuit, at one of two or more pre-determined times in the cycle. In the transmitter. Fig. 3.-Circuits 8 and 9 generate pulses at respective different times in the cycle of the power supply voltage. In accordance with the position of switch 12 one or other of the pulse trains generated is fed via "AND" gate 10 or 11 to a counter 13 which produces an output pulse after, e.g. every 5th pulse. The output from counter 13 is fed to an "AND" gate 15 which is enabled by the output of the counter 14 via a bi-stable 16 so that the "AND" gate 15 passes a predetermined number of pulses, dependent on the scale factor of counter 14, to the pulse generator 17, which may comprise a thyristor in series with a capacitor across the power supply lines L and N. In the receiver, Fig. 4.-The signalling pulses on the A.C. waveforms are detected by discriminator 20 and passed, if they occur in the correct time, relative the A.C. cycle, via "AND" gate 23 to a counter 24 and reset a timer 25. If the correct number of pulses occur to produce an output pulse S1 from the counter 24 at the same time as the timer produces an output pulse P9 and before the timer produces a pulse P11 to reset the counter 24, a pulse P10 is produced to operate, via a bi-stable or flip-flop 28, a relay R/L to indicate the receipt of a correct signal. The operation of the relay may be arranged to change over switch 22 to prepare, after receipt of, e.g. a " 1 " signal, for the receipt of, e.g. a " 0 " signal.

A seed dispenser for attachment to a planter has a housing 22 in which is rotatably mounted a seed carrier 24 having rows of apertures 29 at regular intervals round its periphery and two flat annular end plates 25, 26, the contact between end plate 26 and the stationary wall structure 31 being made airtight by a sealing ring 33. An air pressure differential is achieved between the interior and exterior of the carrier by means of the fan 41, said pressure differential causing seeds fed through a supply spout 39 to the bottom of the drum to become seated on the apertures 29 as they rotate beneath the seeds and then up again. A second air pressure differential is maintained between the interior 30 of the drum 24 and spaces 43 by means of perforated plate 49 which allows air to enter the annular conduit 46. A current of air through aperture 42 into the space 30 is thus created which causes all excess seeds to be swept away from the recessed opening. Release of the seeds from their positions is achieved by release pins 54 supported on mounting arms 55 on shafts 56. Each shaft is attached to an operating arm 62 which rests on a cam 64. Rotation of the arm over the cam edge 65 causes the inward movement of the release pin and consequent release of the seeds which fall into the corresponding tube 37a and thus to the discharge tube 15.
