Title: Improvements in flame supervision devices for burners
Inventor: STEGHART FRITZ LUDWIG FELIX
IPC: F23N5/20
Filed: 1964-07-24
Abstract: 1,079,945. Photo-electric burner control. SATCHWELL CONTROL Ltd. July 23, 1965 [July 24, 1964], No.29767/64. Heading G1A. [Also in Division F4] A burner control system has two normally equal detectors irradiated by the burner flame which supply current to two relays, one relay receiving the sum of the two currents through the detectors and when operated indicates flame presence and the other relay receiving the difference in the two currents: the difference upon reaching a predetermined value indicates malfunctioning of one of the two detectors and the relay operates to shut down the system. As shown in Fig. 1 two detectors 8, 10 responsive to ultraviolet radiation are energized with A.C. from transformer 11 and a first relay FR1 is operated by the sum of the two currents in its coil 3 and a second relay FR2 operated when the unbalance between the currents in the two halves of the centre-tapped coil 7 exceeds the predetermined value. Upon starting up the system by closure of thermostat T, relay FR2 operates via normally closed contact 1 of relay FR1 and its second coil 6 to provide energizing circuits through contact 4 for the ignition device I, supplying sparks to the burner, and the series connection of heater 16 and 22 of bi-metallic strips 13 and 21. The current in heater 22 is as yet insufficient to bend strip 21 but with the additional heater 15 strip 13 bends to close contacts 17 and 19 to energize the fuel pump motor or valve M after which ignition should occur since sparks are being produced. Contact 19 provides a second energizing path for heater 22 completed via contact 4, which if closed would cause strip 21 to be heated sufficiently to bend it, so operating contact 23 to remove power from the system and shut down the burner. If meanwhile the burner has ignited normally, the detectors are irradiated and relay FR1 will have operated to open contact 1, de-energize relay FR2 and so prevent the strip 13 from bending and effecting shut down. Subsequent failure of the flame releases relay FR1 to operate FR2 so heating the strip 13 to effect shut down. Abnormal functioning of one of the detectors 8 and 10 results in unbalanced currents flowing in the two halves of coil 7 which operate relay FR2 and again cause strip 13 to be heated. The detectors and resistor 9 are contained in a probe head, the radiation being directed on to them by a lens or an angularly movable prism Figs. 2 and 3 (not shown).

A row of inward flow gas filtering bags 20 is arranged with the bag mouths opening between vertical mullions 22, and a nozzle is moved to and fro by a reversible motor and discharges reverse flow gas into each bag in succession through a vertical slot 41, which is sealed from adjacent bags by resilient blades 60, carried on the front wall 54 of the nozzle and engaging smooth surfaces formed by snap fastenings which secure the bag side flaps to mullions 22 (as described in Specification 1185336). The upper and lower end flaps of the bags are clamped to flanges on the housing, and the nozzle makes sliding seals with the clamping bars (Figs. 6, 7 not shown). Reverse flow gas may be supplied by an auxiliary source or drawn from the atmosphere by the reduced pressure in the filter housing, and causes sudden expansion of each bag. Fig. 1 (not shown) illustrates the chain drive of the nozzle and the main suction fan (19) of the filter. The nozzle is vertically and horizontally adjustable in its frame, which runs on upper and lower rails by means of grooved wheels (44, 45) (Figs. 5, 6, 10, not shown). Upper wheels (45) are resiliently mounted, permitting removal of the nozzle from the filter housing, and the wall 54 is then removable, with blades 60, from the nozzle.

Filed: 1922-11-06
Abstract: 210,851. Willmot, O. J. Nov. 6, 1922. Locking by positive and frictional detents.-In a hand-truck or trolley of the type which normally runs on a single lateral wheel base and is provided with means for restraining the wheels from rotation, the locking-means, which preferably act in one direction of rotation only and with which a brake may be incorporated, comprises a pawl-and-ratchet clutch which mav be actuated to lock the wheels when the truck-body is in a raised position. In the form shown, the pawl 14, Figs. 1 and' 7, the outer face of which constitutes a brake surface, is drawn into engagement with a ratchet wheel 15 carried by the wheel by means of a spring 16, but its engagement is normally prevented by the interposition of a lug 24 between the leg 29 and the hand-lever 22, the latter being connected to the pawl by a cable 21, passing through the member 9, to levers 17, 18. When the lug 24 is depressed against the action of a spring 25 the pawl engages the ratchet wheel to prevent rearward movement of the wheels, and when the lever 22 is raised to free the pawl the, lug 24 automatically resumes its position, whilst further raising of the lever applies the pawl to the inner surface of the wheel flange to act as a friction brake. As shown in Figs. 1 and 3, the wheels may be carried by plates 11 oscillating about an axis 12 against the resistance of springs 13, in which case the pawl 14 for each wheel is pivoted to one of the plates, and the cable 21 passes into the tube 9 near the axis 12, so that its function is not affected by the suspension system. Grappling members provided with spikes or hooks to engage the load may be coupled to a chain 27 which passes over the load and is anchored to a hook 28.
