Title: Improvements in safety control devices suitable for use with liquid fuel burners in domestic and other heating systems
IPC: F23N5/24
Filed: 1926-06-01
Abstract: 276,095. Marks, E. C. R., (Williams Oil- O-Matic Heating Corporation). June 1, 1926. Electrically controlling fuel and air supplies.- An electric motor M operating the mechanism of a liquid fuel burner in a domestic or other heating system is controlled by a switch 2 operated by a solenoid X which is arranged in a circuit in shunt with the motor circuit and including a room-thermostat T, a safety switch 1, and a thermally-operated switch S arranged in proximity to the burner or in the flue leading to the chimney. The switches 1, 2 consist of mercury tubes provided with counterweights 4 tending to rotate the tubes to such an angle as to break the circuit. 'The switch 1 is fitted with a pawl 5 engaging with a ratchet wheel 6 so as to be held normally in the closed position, the ratchet wheel shaft being carried by a cup 7 which contains solder and is surrounded by a heating coil 9 arranged in parallel with the switch S. In operation on the room temperature falling to a predetermined exbent the movable contact of the thermostat T engages the fixed contact and completes the circuit through the switch 1, coil 9, and solenoid X, thereby closing the switch 2 and starting the motor M. If ignition of the fuel is effected the switch S which preferably consists of a mercury tube 24 similar to the tubes 1, 2 is closed by the heat of the combustion gases and short-circuits the heating coil 9, the combustion continuing until the room is heated to the temperature at which the contacts of the thermostat T separate. If, however, the burner fails to generate heat owing to non-ignition or extinction after ignition, the switch S remains in or moves to the open position and the current through the coil 9 melts the solder in the cup 7, thereby allowing the switch 1 to open and stopping the motor M. In a modification the safety switch 1, heating coil 9, solenoid X, thermostat T and thermally operated switch S are arranged in a low voltage circuit supplied with current from the mains through a transformer.

Title: Flame detection circuits
IPC: F02C7/262
Filed: 1972-03-25
Abstract: 1417984 Burners LUCAS INDUSTRIES Ltd 15 March 1973 [25 March 1972] 14116/72 Heading F4T [Also in Division G1] In a flame-out detection circuit a photovoltaic source monitors the flame, the output of the source being coupled to an ignition circuit via an A.C. amplifier so that flicker of the flame produces in the source a signal which is amplified and applied to hold the ignition circuit de-energized. In the embodiment shown the photo-voltaic source is provided by a photo-diode 31 which receives light from the flame via a light conducting tube 55. The diode is arranged across the input terminal, of an A.C. operational amplifier 28 whose output is connected to a second operational amplifier 29 as shown. The following circuit comprises an A.C. amplitude detector 41, a rectifier 43, a transistor 44, a delay network 45, 46, 48, 49, an amplifier 47, a Schmitt trigger 51 and an output stage 52 connected in series with a relay coil 53 of the ignition circuit. When the flame is present, the detector 41 receives an output signal which is rectified to turn on the transistor 44. Hence no signal passes diode 46 so that the Schmitt trigger produces an output to the stage 52 to energize relay 53 and close contacts 54 to prevent operation of the ignition circuit. If the flame is extinguished, the dector 41 ceases to produce an output so that after a delay, during which capacitor 48 is charged through resistor 45, the Schmitt trigger provides an output causing relay 53 to be de-energized to energize the ignition circuit. The ignition circuit is then not turned off for a predetermined time after the flame has been re-established during which capacitor 48 discharges through resistor 49. As shown metallic shields 11, 12 are provided to shield components from external A.C. interference signals.

Title: Improvements in and relating to textile mill finishing machines
IPC: D06C13/02
Filed: 1964-04-13
Abstract: The seams joining successive pieces of fabric being shorn in a fabric shear are protected from injury by the shearing knives by providing a thread in each seam which thread is responsive to invisible radiant energy of a selected frequency to emit visible light; activating the thread at a zone spaced a selected distance from the shearing knives with radiant energy of said selected frequency; photo-electrically detecting visible light omitted by the thread at the zone; and generating signals responsive to detection of the emitted visible light a selected delay interval after detection thereof correlated to the spacing of the zone from the knives to momentarily lift the knives above the surface of the fabric.  The thread may be the thread with which the seam is stitched and is treated with a fluorescent dye which glows when activated by radiation frequencies in the invisible range, e.g. ultra-violet radiation.  The fabric is shielded from ambient light and photocells are evenly spaced across the width of the advancing fabric with the outermost cells located close to the lateral margins of the cloth.  Medium blue filter paper may be interposed in the paths of the light of the photocells.  The plurality of photocells is provided to effect accurate detection of seams which are not straight.  A detection signal is generated immediately upon detection of the visible light by any one of the photocells. A first delayed signal is generated a selected time after generation of the detection signal and a second delayed signal p responsive to the first delayed signal is generated after a selected time delay relative to the latter.  The second delayed signal causes the knives to be raised from the surface of the fabric being sheared. If visible light is detected by only one of the photocells means is provided to disable the first delayed signal to prevent the second delayed signal being produced.  The knives are lowered after the seam has passed.  An electrical circuit is described.
