Title: Improvements in or relating to combustion control systems
IPC: F23N5/08
Filed: 1966-08-15
Abstract: 1,110,376. Burner control. ELECTRONICS CORPORATION OF AMERICA. 15 Aug., 1966 [31 Aug., 1965], No. 36360/66. Heading F4T. A combustion control system comprises a flame sensor, an air blower, devices for controlling the flow and igniting the fuel, a rotary timer for sequentially initiating an ignition sequence and a combustion sequence in a combustion control cycle, a purge timer, and means to prevent initiation of the ignition sequence by the rotary timer until completion of the purge time. The rotary timer comprises a series of cams mounted on a shaft and makes one revolution per 30 seconds. The system is operated by closing a limit control and operating control which energize a control relay and hence the blower and the rotary timer. After 4 seconds the rotary timer stops and purging takes place for one minute, after which the rotary timer restarts and the ignition cycle commences. The purge timer will not operate unless the blower is operating. An optional fuel/air ratio damper will at this time be automatically set to the low firing position during an interruption in the ignition cycle. A contact of the control relay completes a circuit through the rotary timer to energize a transformer to render a flame sensor operative. Ignition commences after 10 seconds of the rotary timer by energization of the ignition transformer and a pilot valve, and after a further 5 seconds the main fuel valve is opened. Unless a flame relay is now energized by the flame sensor the system will be de-energized. A safety cutout heater has its electrical continuity checked during the above five seconds. Also after the 10 seconds of rotary timer, should there be an actual flame in the combustion chamber or a fault in the system which indicates a flame the safety cutout heater will operate, while after the start of ignition the safety cutout heater is energized until the flame relay is energized by the flame sensor. Interruption of the flame will cause the cutout heater to be re-energized and will cut off the fuel and operate an alarm. A safety circuit ensures that the main fuel supply is turned on only after a flame has been established and the pilot fuel supply and igniter are turned off two seconds after the main fuel supply is switched on. Should the transfer from pilot flame to main flame not take place in these two seconds the system will shut down.

Title: Electro-optical position monitoring and control means
IPC: G01D5/34
Filed: 1974-08-22
Abstract: 1521263 Optical position sensor T I (GROUP SERVICES) Ltd 15 Aug 1975 [22 Aug 1974] 36859/74 Heading G1A Means for setting a member at a datum line has an optical device which can form an image of the member at a plane including an array of photoelectric elements defining the datum line, electrical means for scanning the elements and producing a signal for a pre-set change of illumination of any element resulting from the intrusion of the member across the line. Tool tip 1 is illuminated by lamp 2 via condenser lens 3. Objective lens 4 (or in its conjugate position, 4a) via beam-splitter 7 forms images of tip 1 on graticules carrying slits 5 and 6, images of which are formed on arrays of photodiodes 10, 11 by lenses 8, 9. Facing splitter 7, the graticules are metal coated to reflect light back to eye-piece train 13, 14 for viewing by the eye-piece or a television monitor. Vignetting is prevented by lenses 15, 16. The scan rate is between 30 Hz and 30 kHz. A pulse from clockpulse generator (17) Fig. 2 (not shown) initiates the scan of photodiodes (10) by driver circuit (18). Their output is fed to circuits (20, 21) determining the maximum and minimum levels attained by the signal and circuit (22) gives the mean of these as a reference for comparator (23), receiving the photo-diodes' output directly, and which feeds decoding circuit (24) which may give logic 0 or 1 output. Arrays of photo-cells with additional slits parallel to slits 5 and 6 may sense the approach of the tool tip. Lenses 8 and 9 may be omitted and the photodiodes mounted close to the slits. A two dimensional array or television camera with a mask with two differently directed slits may be used and the beam-splitter omitted. The optical components are housed in holes in one or more solid blocks, there being two bores, at the intersection of which the beam-splitter is located.
