Title: Video amplifier
IPC: G06V30/10
Filed: 1963-09-03
Abstract: 1,038,634. Transistor amplifying circuits. SPERRY RAND CORPORATION. Sept. 3, 1963 [Sept. 7, 1962], No. 34736/63. Heading H3T. [Also in Division G4] In a character reader an amplifier for the video output of the scanner consisting of character data signals and blanking signals comprises a number of transistor stages the last of which is connected to a shunt gate adapted to remove the blanking signals. The characters are sensed by a camera tube scanner making a number of parallel scans through the character. The flyback is blanked so that the photo-cell output contains blanking signals 82, Fig. 3 (not shown), at each end of a scan and data signals 84 between. When a group of five characters are scanned, there being about ten scans as illustrated in Fig. 3 (not shown), for each character, the composite video signal is as illustrated in Fig. 4 (not shown), the scan groups being at 84<SP>1</SP> and the blanking signal envelope as shown at 82. The video signal is applied through potentiometer 22, Fig. 1 (not shown), and capacitor 24 to amplifier transistor T1. The output is passed to the base of second stage amplifier transistor T5 through capacitor 36. The output of T5 is applied through capacitor 42 to the bases of T3 and T4 to obtain the signal of Fig. 5 (not shown), the base line 49 being substantially unchanged but the other signals being much amplified. Transistor T3 serves to charge the capacitor 48 to the most negative input signals, i.e. base line 49, and this is applied through transistor T2 and resistor 54 to the base of transistor T4 so as to be subtracted from the amplified video signal. The output of T4, Fig. 7 (not shown), is applied through capacitor 58 to transistor T6 connected as an emitterfollower. The output is modified by shunt gate T7 which is operated at blanking times to short out the blanking signals 82, leaving the character signals only as in Fig. 8 (not shown).

Title: Analog to digital translators
IPC: H03M1/00
Filed: 1957-11-08
Abstract: 811,267. Electric selective signalling systems. STANDARD TELEPHONES & CABLES Ltd. Nov. 8, 1957 [Nov. 9, 1956], No. 34887/57. Class 40 (1). In a shaft digitizer (that is a device for producing digital electric signals representative of a shaft position) using a plurality of monophylically coded binary discs appropriately geared together, there being one for each decimal denomination, and in which each disc, except the units order disc, has two sets of sensing brushes-a lead set and a lag set-(the lead set being positioned slightly ahead of the theoretical sensing position and the lag set slightly behind), the actual set of brushes used for reading any one disc is determined by whether the adjacent lower order disc is registering 0 to 4 or 5 to 9. As described, three discs 10, 11, 12, Fig. 1, are read serially by bit and serially by disc starting with the bits of the units disc 10, and each disc is so coded (see Fig. 2, not shown), that the last bit to be read is 0 for the range 0 to 4 and 1 for the range 5 to 9. A complete read operation is as follows: initially a read matrix is controlled so as to pass only pulses coming from disc 10; a scan generator then pulses four lines 24 to 27 in succession, thereby reading out the units disc 10 to an output; the last bit read from disc 10 is examined by an and gate 28 and if it is a 1 it causes a lead line 35 of a selector 34 to become positive-it it is an 0 it causes a lag line 36 to become positive; the read matrix is then controlled to pass pulses from disc 11 and the next four pulses from the scan generator, applied successively to leads 24 to 27, are routed via a scan matrix to either the lead brushes or the lag brushes as determined by the selector 34; this causes the read out of the tens disc and the hundreds disc 12 is read out in a similar manner.

Title: Improvements in surface coatings of powdered material and in the method of applying the same
IPC: H01J9/22
Filed: 1936-12-23
Abstract: 484,511. Ornamenting. ROGERS RADIO TUBES, Ltd. Dec. 23, 1936, No. 35251. Convention date, Jan. 11. [Class 93] [Also in Group XX] A coating of powder is formed on a surface as of metal or glass, e.g. a luminescent coating on a cathode-ray tube, by cleaning the surface, exposing it to the products of incomplete combustion of a compound of sulphur in order to form by condensation a layer of sulphur on the surface, dusting finely powdered material evenly on the layer, removing excess of powder, and then heating to evaporate the sulphur layer, so that the powder coating is left adhering directly to the surface. The Figure shows an apparatus wherein the end of a cleaned cathode-ray tube is coated with sulphur produced by burning carbon bisulphide contained in a holder 4 heated electrically by a coil 5, in a slow draught produced by an aspirator attached at 8, the products of combustion being drawn up a tube 2 with a jacket 7 leading to the aspirator tube 8 and being dispersed over the end wall of the ray tube 1 by a plug 6 on the top of tube 2. After wiping off any undesired sulphur at the edge of the layer, powdered luminescent material such as synthetic willemite activated with manganese, or zinc sulphide from which copper and other impurities have been removed, is dusted on evenly the excess wiped off, and heat applied to evaporate the sulphur. Specification 458,635, [Group XX], is referred to. The Specification as open to inspection under Sect. 91 states also that the condensation layer may be formed by exposure to the products of incomplete combustion of compounds of other elements. This subject-matter does not appear in the Specification as accepted.

Title: Fluidic control apparatus for aircraft fuel systems
IPC: B64D37/00
Filed: 1976-08-25
Abstract: 1520300 Fluidic control circuits GARRETT CORP 25 Aug 1976 [25 Aug 1975] 35270/76 Heading F1P In the circuit shown, Fig. 1, a fluid input signal is compared with an oscillatory signal of substantially trapezoidal waveform and the result of the comparison is amplified, in an amplifier 48, to produce an output signal which, when the input signal lies within a certain range, is a square wave signal which alternates between two predetermined values and has a time average value which is dependent on the value of the input signal, and, when the input signal lies outside that range, is a steady signal having one of the two said values. As described, the circuit controls fuel flow in an aircraft engine during landing. An angle of attack signal is integrated in an integrator 58 and this signal is algebraically summed with other signals, after appropriate modifications of the magnitude thereof, to produce a single signal representative of the desired rate of fuel flow. This signal is temperature compensated by a compensator 60 and fed to a gain selector 62. By appropriate positioning of a switch 50, the gain of an amplifier in the gain selector is set according to ambient environmental conditions so that the signal is modified accordingly. The flow of fuel to the engine is sensed through the angular position of a lever 40 and transformed into a fluidic signal through pin amplifier 66. The difference between the two signals is an error signal whose magnitude is proportional to the required change in fluid-flow and thus the required rotation of lever 40. This error signal is impressed on a trapezoidal time varying signal to bias the latter and drive a power amplifier 48. The output of this amplifier is used to drive an actuator 32 until the desired fuel flow is produced.

Title: Improvements in or relating to radar systems
Inventor: RIGNALL MICHAEL WILLIAM
IPC: G01S13/92
Filed: 1958-11-03
Abstract: 856,495. Radar. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Aug. 24,1959. [Nov. 3, 1958], No. 35276/58, Class 40(7). In a velocity measuring Doppler radar systems a voltage representative of the Doppler frequency is stored and measured and whilst being stored the application of further Doppler representative voltages to the storage means is prevented. The invention is described in connection with a police radar system employing a narrow transmitted beam to enable the speed of a particular vehicle, which may be followed closely by another vehicle, to be measured. In the arrangement described the Doppler frequency, derived via a conventional F.M. Doppler radar system 1-19, is supplied via condensers 20, 21, to trigger a multi-vibrator 22, 23 producing constant-amplitude constant-width pulses of Doppler frequency which are supplied via amplifier 24 and a condenser 25 (to remove the D.C. component) to a rectifier 27 the rectified voltage from which changes condenser 29 to a potential representative of the Doppler frequency. A measure of this voltage is then produced by a meter 30 which may be calibrated directly in terms of speed. When the voltage across resitor 31 reaches a predetermined minimum value (corresponding to a predetermined minimum speed) a normally conducting transistor 33 is cut-off thus making a normally cut-off transistor 39 conductive which changes the potential at the junction of condensers 20, 21 to a value sufficient to arrest the operation of multi-vibrator 22, 23. The reading of meter 30 corresponding to the predetermined minimum speed is then held irrespective of other vehicles entering the beam of the transmitter. After a period in this condition, determined by the time constant of condenser 41 and resistor 42, a normally cut-off transistor 34 is rendered conductive and energizes a relay coil 36 the contacts 37 of which close and short-circuit condenser 29. The apparatus then reverts to its initial condition.
