Abstract: 1,056,972. Gas burners. NATIONAL RESEARCH DEVELOPMENT CORPORATION May 5, 1965 [May 6, 1964; Aug. 12, 1964], Nos. 18764/64 and 32944/64. Heading F4T. A gas burner comprises a burner head 17 having a series of flame ports, each divided by two partitions 26 to form a central section producing a fan - shaped flame and two outer sections producing flames which prevent the central flame from lifting off. The burner shown in Fig. 3 is elongated and the burner head is wedgeshaped; the flame ports are rectangular and extend transversely across the apex of the burner head. The partitions 26 are the vertical walls of two L-shaped plates extending along the burner head and forming therewith two low pressure compartments 32. The space between the plates constitutes a high pressure compartment communicating with a mixing tube and gas injector. Gas is supplied from the high-pressure compartment to the low-pressure compartments 32 through a series of apertures 31 in the partitions or through small tubes; alternatively, the low-pressure compartments are fed from a separate source. A central flat plate 25 may be secured between the two partitions. The partitions may be spaced by projections formed on the partitions or by a corrugated plate disposed between the partitions. A series of burner heads may be arranged side-by-side or in the form of a star. A ring burner, Figs. 4, 5 (not shown), comprises a cylindrical casing 40 closed at the top by a circular cap 41. The mating edges of the casing and cap are chamfered and cut away at spaced intervals to provide flame ports. A flared tube 47 is disposed within the casing and forms therewith an annular low-pressure compartment 48; and a disc 49 is mounted on spacer elements 50 on the tube 47 and forms with the cap 41 a second low-pressure compartment 51 Small apertures 53, 54 permit flow of gas into the two low-pressure compartments. The circular edge of the disc 49 and the edge of the tube 47 divide the flame ports into three sections. The burner of Figs. 6, 7 (not shown), comprises a tube having circular flame ports. A U-shaped insert extends the length of the tube and the upper edges of the inset divide each flame port into three sections. Two low-pressure compartments 69 are formed between the side walls of the insert and the inside of the tube. The burner of Figs. 8, 9, 10 (not shown), comprises a vertical tube having a tapered nose provided with a central rectangular flame port. A recess leading to the flame port is bounded by two converging end walls 74 and two vertical side walls 75. Two V-shaped partitions 77 are disposed within the tube and have upwardlyprojecting concave tongues 78 which abut against the vertical side walls 75 of the nose and divide the flame port into three sections. The partitions fbrm two low-pressure compartments with the inside of the tube.

Abstract: 811,048. Radio signalling; valve oscillator circuits. ELECTRONIQUE APPLIQUEE. June 14, 1957 [June 19, 1956; June 6, 1957], No. 18819/57. Classes 40 (5) and 40 (6). [Also in Group XXXVII] In an apparatus for automatically keying an emergency radio transmitter by electrical contacts cam-operated by an asynchronous motor, the stator of the motor forms part of the oscillatory circuit of a low-frequency valve oscillator, the motor thus being driven by the alternating voltage generated by the oscillator. As shown the double triode push-pull oscillator valve 18 has the stator winding 5 of a small asynchronous motor included in the resonant circuit, the circuit being arranged to oscillate at a frequency of 50 to 60 cycles per second. Through reduction gearing 7 the motor drives a coding drum 10, carrying for example an identification or emergency code, which operates a changeover switch 27 accordingly. The coded portion of the drum causes the switch 27 to connect the low-frequency amplifier 28 as an oscillator and cause it to modulate the crystal-controlled transmitter 16 in accordance with the code. When the uncoded portion of the drum 10 is reached, the feedback connection of the amplifier 28 is removed and the output of a transistor amplifier 31 is applied via the amplifier 28 to amplitude modulate the transmitter in accordance with the noise, e.g. air noise, subterranean noise, or submarine noise, picked up by a microphone 30. The noise pick-up is also utilized to start the apparatus, the output from the microphone being amplified by further transistors to operate a relay 33 and close the contact 34. The contact 34 switches on the heater of the valve 18 and may also be arranged to switch on the heaters of the transmitter valves. A potentiometer 36 determines the threshold value at which the relay 33 operates and a capacitor 35 shunting the relay prevents its operation by transients. In an alternative arrangement, Fig. 1 (not shown) the transistor amplifier and microphone are dispensed with and the apparatus is manually switched to provide automatic keying, manual keying, or the emission of a continuous wave from the transmitter 16 The code drum may be arranged to key a plurality of different carrier frequencies in a predetermined sequence.

Title: Improvements in apparatus for signalling angular displacement
Inventor: PERRETT BRIAN RAYMOND
IPC: G08C19/48
Filed: 1969-04-16
Abstract: 1298669 Computing angular displacements BRITISH AIRCRAFT CORP 8 April 1970 [16 April 1969] 19435/69 Heading G4G A signal representing the angular displacement of a body comprises means for deriving from a synchro transmitter or resolver first and second signals each representing a different product of two terms, viz. a sin or cos function of the supply angular frequency #t and a sin or cos function of the rotor angle #; means for deriving from the first of these signals a further signal which is of the same form as the second signal but with sin and cos reversed; means for adding the further and second signals and means for comparing the sum with the corresponding sin or cos of the supply angle to obtain a rotor angle signal. For example, the first and second signals may be sin #t sin # and sin #t cos #. From the first, a further signal cos #t sin # is derived and added to the second signal to obtain sin (#t + #). This signal is then compared with sin #t to obtain a signal representing #. The three stator windings of a synchro transmitter provide on lines 10, 12, 14 the signals indicated on the drawing and these are fed to centretapped transformers T1 and transformer T2, with earthed secondary, in the manner shown. Link L2 is closed to provide a Scott connection between the primaries, but if a resolver is used to provide the inputs, link L2 is closed instead. A potentiometer P1 connected to the secondary of T2 provides a signal representing V 1 /2 sin #t 2 sin # whilst the two ends of the secondary of T 1  respectively yield  V 1  sin #t cos #. The first of these signals is converted to V 1 /2 cos #t sin # by means of a circuit consisting of an integrator 16 in parallel with an inverting circuit 18 and a differentiator 20. It is shown in the Specification that the sum of the outputs of circuits 16 and 20 is proportional to - cos #t sin and that the operation of the circuitry minimizes the effect of frequency drift (##) on amplitude. This latter signal is added to the other two signals in two half-Wien summers 22, 24 which yield respectively sin (#t-#) and sin (#t + #). The angular value # flies back to zero at intervals of 180 degrees. To obtain an output which flies back every 45 degrees, the signals are each fed through two frequency doublers 26, 30 and 28, 30 and signals sin (4 #t  #) are derived. These are respectively fed to triggers 36, 34 which convert them from sinusoids to square waves. The signal from trigger 34 is fed to a " set zero " circuit 40 which has the same effect as rotating the body of the synchro to zeroize #. The zeroized signal is compared with the signal from trigger 36 in a bi-stable circuit 38 the opposite outputs of which control respective F.E.T. switches 42, 44. These receive -ve and +ve reference voltages from a supply 45, 46, 48. The output of the switches is fed to a low-pass filter 50 and represents the angle . The frequency-doublers and trigger circuits are of conventional design.
