Title: Improvements in or relating to digital-to-analogue conversion and control apparatus
IPC: G05B19/33
Filed: 1956-06-15
Abstract: 820,406. Electric selective signalling systems. GIDDINGS & LEWIS MACHINE TOOL CO. June 15, 1956 [June 23, 1955], No. 18588/56. Class 40 (1). In a digital-to-analogue converter, data is read from a punched tele-type record tape, staticized on electromagnetic relays and converted into a form in which it is represented by the phase difference between two constant-frequency pulse trains. The converter shown in Fig. 1 handles five individual channels of data, each channel, for example channel 1, comprising a frequency-divider FD1 (8 cascaded flip-flops), receiving pulses from a reference pulse generator 10 via an input gate G1 and producing a squarewave pulse train, as shown, which, when it represents no data, is in phase with, and identical to, a reference pulse train produced from pulses from the reference pulse generator by a frequency-divider 12 identical to that used in each data channel. Thus each generated square pulse is " up " for a period of 256 reference pulses from the reference pulse generator and then down for 256 reference pulses. The output pulse train from channel 1 can be made either to lead the reference pulse train-to represent positive data-by feeding extra pulses, interleaved with the reference pulses, to the frequency divider FD1 via a lead 34, or to lag behind the reference pulse train by stopping some of the pulses from the reference pulse generator reaching the frequency-divider. This is done by a pulse deleting circuit PD1, which, under the control of pulses on line 36, closes the gate G1 at the appropriate times. Thus, if, for example, six pulses are entered on line 34 then the output pulse train from channel 1 will lead the reference pulse train by six reference pulses and if six pulses are entered on line 36 then it will lag behind the reference pulse train by six reference pulses. The pulses on the lines 34 and 36 are obtained from the data read from the punched tape.

Title: Radio transmission system
IPC: H03C1/22
Filed: 1920-07-05
Abstract: 146,519. Western Electric Co., (Assignees of Heising, R. A.). Oct. 2, 1916, [Convention date]. Wireless telegraphy and signalling; electric oscillations, producing.-In order to give a negative potential to the grip of a tricde valve without providing a special battery, use is made of the potential difference which arises between the ends of a resistance connected in series with the grid of another valve which is generating oscillations. The valve 1 acts as an oscillation-generator, the plate circuit being connected to the grid through a variable condenser 7. A second condenser 9 provides a path for the plate-circuit oscillations other than that through the high-tension battery 3. The grid-current consists of unidirectional pulsations which can be resolved into a direct and an oscillatory component. Consequently a net potential difference obtains between the ends of the resistance 10 in the grid circuit, a condenser 11 serving to shunt the oscillatory component. The oscillations transmitted by the apparatus are taken from the plate circuits of the valves 13, and the grid circuits of these valves include in series (a) the secondary of the modulating transformer 14, (b) the secondary of the high frequency transformer 15, and (c) a portion of the resistance 10 which imparts a negative potential to the grids 5<1>.

A focal plane shutter comprises a leading and a following rigid shutter blind, each driven by a laterally engaging crank which is connected to a spring loaded driving member and is characterized in that a range is provided in the drive of the shutter blinds in which the start of the movement of the following blind is effected within an adjustable time interval after the leading blind has come to rest. In the apparatus shown, the two blinds are slidably and rotatably mounted behind a plate 2 and each have at one end a pin 5, 6 respectively which engage notches in the ends of cranks 18,19 which are rotatable about a point 40a. The movement of the cranks and hence of the shutter blinds is controlled by links 26, 27 which have pins 31,31<SP>1</SP> which engage slots 22 in the cranks and slots 32, 33 in plate 2 and pins 28, 281 which engage aperture 29 in a disc 24 and slot 30 in a disc 25 respectively. The two discs 24, 25 are coupled together by a pawl 35 and ratchet teeth so that they can be driven together by a spring 34 when the lever 47 is moved from lug 46. Pins 44, 37, on pawl 35 engage apertures 41, 43 on a disc 39 so that when the disc is rotated anticlockwise to set the shutter speed, pawl 35 is rotated out of engagement of teeth 36 and disc 25 moves relative to disc 24. For short exposure times pins 31, 31<SP>1</SP> are at points 49, 51 in slots 32, 33 respectively and both shutter blinds move simultaneously. Pin 28<SP>1</SP> is at the lower edge of slot 30. For a longer speed pin, pins 31, 31<SP>1</SP> are arranged initially at points 49, 53 respectively so that the following shutter blind only starts to move when pin 31<SP>1</SP> has reached point 51 and the full frame is exposed for a short instant. For an even longer exposure time pin 28<SP>1</SP> is arranged at the upper end of slot 30 and the pins 31, 31<SP>1</SP> at points 49, 53, in which case the pin following shutter blind is not moved until pin 281 has reached the bottom of slot 30 and pin 31<SP>1</SP> has subsequently moved from point 53 to 51. An additional rotatable lever 54 is provided one end of which can co-operate with lug 46 for bulb exposures. An exposure metal may be arranged on one of the shutter blinds.

Abstract: 967,688. Calibrating bearing of radar display. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 17, 1963 [May 17, 1962], No. 19104/62. Heading H4D. Radar equipment wherein angular synchronism between the rotation of the aerial 1 and the rotation of the scan coil 6 may be automatically achieved, comprises a motor 2 driving the aerial 1 and also two alternators 3 and 4 through gear trains 8 and 9 having slightly different step-up ratios. A synchronous motor 5 drives the scan coil 6 through a step-down gear train 10, and is fed from either of the two alternators via a two-way switch 7. The switch is controlled by a relay coil 13, which is actuated by the simultaneous closure of two switches 11 and 12, under the control of cams on the shafts of motors 2 and 5. The positions of the cams are such that actuation of the relay coil occurs when the aerial and scan coil are in alignment. The ratios of the various gears are such that when the motor 5 is fed from alternator 3, the scan coil rotates at the same speed as the aerial, whilst when the motor is fed from the alternator 4, the scan coil rotates at a slightly different speed from the aerial. In the synchronizing process the scan coil is stopped when it reaches a predetermined posi tion, until the aerial reaches a corresponding position, when it is restarted. Due to internal considerations &c. the scan coil and aerial will not be in alignment by the time the scan coil has reached full rotation speed. The motor 5 is therefore fed from alternator 4 such that the slight difference produced thereby in the rotational speeds of the aerial and scan coil causes the misalignment to be gradually reduced. When the aerial and scan coil are aligned, switches 11 and 12 are closed, coil 13 is actuated, switching over switch 7, and the motor 5 is fed from alternator 3 to maintain the synchronism between the aerial and scan coil.
