Title: Flame detector
IPC: F23N5/08
Filed: 1963-10-30
Abstract: 1,037,234. Transistor pulse circuits. COMBUSTION ENGINEERING Inc. Oct. 30, 1963 [Nov. 2, 1962 (2)], No. 42813/63. Heading H3T. [Also in Division G1] In a flame detector, random pulses produced by avalanche processes in a glow discharge detector tubes due to radiation from the flame, are transmitted to a receiver circuit which includes e.g. a relay which actuates an indicator to show whether or not the flame is alight. The lightly loaded transmitter circuit includes the discharge tubes UV (Fig. 8) arranged to produce pulses superimposed randomly as voltage spikes on the A.C. supply waveform from 10. The duration of the pulses is increased by means of R 1  and C 1 . The pulses are separated from the supply by means of capacitors C 2  and C 4  and the negative pulses shorted to earth through diode D 2 . The positive pulses trigger on an S.C.R. the signals from which are stored in a tank circuit K L , C 5 . The diode D 1  produces halfwave rectification for the receiver supply. On extinction of the flame, the pulses from the U.V. tubes stop and the relay is caused to actuate an alarm or indicator. A circuit to check whether or not the S.C.R. and other components are operating correctly, involves a bridge rectifier 26, tuned to a band of frequencies about the random signal frequency, having a relay 28 which can operate an alarm 34 if a fault is detected, and which can be connected either across the relay R L  or across the secondary of a transformer (Fig. 9, not shown), the primary of which is connected in the output of the receiver. Various modifications of the receiver circuit are described. In one (Fig. 4, not shown), negative pulses from the transmitter switch on the transistor Q 1  and capacitor C 6  is charged to a desired value, and increases the time constant of the gate pulse to the S.C.R. The rate of firing of the S.C.R. is again dependent on the rate of pulses from the tubes UV. The capacitor C 7  helps the S.C.R. to recover after each pulse. The circuit has a full-wave rectified supply at a low voltage, an alternative highvoltage circuit being provided in a circuit which includes a Zener diode and a resistor to limit the voltage across the transistor (Fig. 5, not shown). In a high-voltage circuit which may be supplied by a half-wave supply (Fig. 6, not shown), the capacitor C 6  may be omitted since a shorter gating time is required for a higher voltage S.C.R. A transistor Q 2  (Fig. 7, not shown) may be used to receive the pulses from the transmitter and forms part of an emitter follower circuit. The emitter-collector current is limited by resistor R 6 . C 8  acts to store some of the energy of Q 1  to maintain Q 3  turned on between signal pulses to Q 2 . Transistor amplifier stages are provided with relay R L  as the load for transistor Q 4 .

Apparatus for finishing parallel faces of a workpiece rotatable about an axis perpendicular to the faces comprises: (a) a housing mounted for reciprocation in a plane perpendicular to the axis, the housing including at least one pair of parallel spaced longitudinally extending guide surfaces; (b) a pair of abrasive stones carried by the housing for movement therewith; and (c) means carried by the housing and movable along the guide surfaces for moving the stones into engagement with a workpiece face. The disc 14, Fig. 1, of a disc brake is supported between fixtures, one of which is rotatably supported by an adjustable hand wheel 16 and the other is carried by the shaft of an electric motor 18 serving to rotate the disc. Two opposing pairs of abrasive tool assemblies are mounted in a tool housing 23 vertically reciprocated on a fixed frame 13 by an hydraulic cylinder 15. Each tool assembly comprises an abrasive stone 33 fixed to a holder 35, Fig. 3 (not shown). Each holder has longitudinally spaced tapered rear faces 37 engaging tapered faces 39 on a plate 41 slidable in a groove in the tool housing. To advance the stone into contact with the workpiece, pressure fluid is admitted through inlet 51 and acts on a piston 43 to move the plate 41 downwards. To remove the plate 41 upwards, pressure fluid is admitted through inlet 63 and acts on a piston 55, the stone being retracted from the workpiece by leaf springs 65. In operation, the workpiece is mounted between the fixtures and the motor 18 actuated to rotate the workpiece. With the stones retracted the tool housing 23 is lowered. The stones are advanced into contact with the workpieces and the housing reciprocated rapidly to produce a random surface grain structure or slowly to produce a concentric surface grain structure. The operation may be terminated by a timer or by a gauging device. In a modification. Fig. 7 (not shown), the tool housing 23 is reciprocated through a connecting rod 75 by a crank-pin 77 on a disc 73 driven by a variable speed motor. The workpiece 14 is raised into finishing position by a lift 83 hydraulically or otherwise actuated, and having a concavity 85 to cradle the workpiece. One fixture 87 is reciprocable by a fluid motor 89 or a hand wheel and has a tapered end portion 91 engaging a central opening 93 in the workpiece to raise it clear of the lift and press it into engagement with the other fixture. The workpieces may be handled automatically.
