Title: Apparatus for controlling automatic burners
IPC: F23N5/20
Filed: 1971-07-19
Abstract: 1363272 Burner controllers RIELLO BRUCIATORI OFFICINE FONDERIE F LLI RIELLO LEGNAGO S A S DI PILADE RIELLO & C 19 July 1971 [22 July 1970 8 Oct 1970 19 May 1971] 33838/71 Heading F4T A burner controller comprises an ignition transformer TA, fuel-flow initiating means including a first coil or coil part E of an electromagnetic liquid fuel valve, fuel-flow maintaining means including a second coil or coil part R of the valve, and a two-state relay the solenoid RF of which is connected to a flame-sensor F, the relay having contacts IRF which in a first state corresponding to "no flame" connect transformer TA and coil E to electrical supply terminals, and in a second state corresponding to "flame present" contacts IRF charge to energize coil A and render transformer TA inoperative. On closure of a thermostat T transformer TA and a burner motor M, driving an air fan and fuel pump, are energized but fuel is initially just recirculated without passing to the burner until a bimetal heater PV closes contacts IPV to energize a second bimetal heater BF and valve coil E to open the valve. If no ignition occurs before heater BF changes over contacts IBF a lamp L lights, the other burner components are de-energized and a manual reset of contacts IBF is required before another start-up can be intiated. If ignition occurs before contacts IBF operate, photoresistor F conducts to energize relay coil RF whereby make-before-break contacts IRF change over to energize the valve-holding coil R and de-energize E, BF and TA, contacts IPV opening after a time due to the lower current through PV and R. If the flame is extinguished, re-ignition is attempted. In modifications:-  heater BF may be omitted and heater PV arranged to close contacts IPV and, in response to prolonged energization, to operate contacts IBF; heater PV may alternatively be connected between transformer TA and contact 8 of contacts IRF, Figs. 6, 7, 9 (not shown); and coils E and F may be arranged so that E alone opens the valve and E and R are connected in series to hold the valve open, Fig. 7. In a further modification, Fig. 9, the open-close contacts IPV are replaced by change over contacts IPV (14) (19B) arranged so that following ignition and cool-down of heater PV, these contacts open a second valve, supplying fuel to a second flame of the burner ignited by the first, by means of a coil (II V) which said contacts connect in series with heater PV and transformer TA, the current being insufficient to produce ignition sparks from TA. The second valve is hydraulically in series and downstream of the first.

Abstract: 387,471. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and PETERS, C. L., 53, Penberth Road, Catford, both in London. Dec. 14, 1931, No. 34607. [Class 40 (iv).] A register-marker which can be associated with any one of a number of first stage switches also marks the terminals of second stage switches. The invention is described with reference to a system in which the register marker is part of an " operator circuit " and which is identical with that described in Specification 328,752, [Class 40 (iv), Telephones &c.], except for details incidental to the fact that two stages of numerical switches are provided, the first giving access to junctions to one or more exchanges and to one or more groups of final switches. For this reason the " operator circuit " includes a hundreds register which exercises the various discriminating functions for distinguishing between different kinds of call performed in the prior system by the tens register. Local call. When a call is made, the combined associating and sequence switch CCF in the assigned operator circuit selects an idle link of which the finder CF selects the calling line and the conversation switch CS takes a step all as described in Specification 328,752. Relay A 'repeats the digits to the magnets DH, DT; DU of the hundreds, tens and units registers, the sequence being looked after by relays G, H under control of the dialling relay D. When the latter falls after the units digit and provided the other " operator circuit " is not marking, E pulls up and makes driving and marking circuits whereby the switch CS hunts for an idle final switch under control of S which pulls up in series with LS in the 1st idle final switch in the group marked over DH3 and switches the driving circuit via wiper D of CS to the magnet DP of the final switch. The latter is stopped by the two-step relay LT when wiper d encounters the marking potential applied over wipers DT3, DU2 .. 6. Relay F which has hitherto been held in the driving circuit now releases G and connects up the test relay P. If the line is idle, P pulls up in series with the wanted cut-off relay and with winding (ii) of LT which then operates its contact lt1. The operation of P and relapse of G step CCF into the ringing position. Outgoing calls. When an outgoing 1st digit is dialled, the hundreds register wiper DH5 energizes JT which short-circuits F. On the relapse of D, G and E pull up and CS hunts for a junction in the group marked by wiper DH3, under control of S. P then operates in series with CO in the junction circuit and the junction is rung.

Abstract: 655,369. Electric control systems. STAATSBEDRIJF DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Dec. 30, 1947, No. 34842. Convention date, April 25, 1944. [Class 40 (i)] [Also in Groups XXXIX and XL (b)] In a bridge-marking telephone or telegraph exchange system, wherein each character or the like is transmitted as a different potential, an exchange register arrangement comprises a plurality of elements each comprising a voltage-responsive device and a relay, the number of such elements being less than the number of characters to be received, and each voltage-responsive device is connected on one side to the receiving line, and on the other side normally to a respective tapping point on a potential divider and each relay when operated re-arranges the connections of all devices normally connected to tapping points at lower potentials than that to which its associated voltageresponsive device is normally connected so as to connect them to points at higher potentials. Characters, e.g. digits are each transmitted as a characteristic voltage from a selected tapping on a potentiometer W0, W9. The received voltage is applied to the cathodes of four thermionic valves BA ... BD which are arranged with graded bias of the voltages shown from a potentiometer W10 ... W22. With a no signal condition of - 30 volts no valves will conduct but with voltages between - 32 and - 54 volts, from one to four of the valves will conduct and their anode relays A ... D will operate. The contacts of these relays are so arranged that for each of fifteen 2-volt steps in the received voltage a different combination of relays A ... D remains operated. By assigning to the relays the values 1, 2, 4 and 8 any digit from 1 to 10 can be indi. cated by an operated combination. In general with n tubes and relays 2n characters may be indicated. Auxiliary contacts of the relays A ... D may operate register relays (not shown), and it may be arranged that the relays A ... D are given operating delays of say 25, 20, 15 and 10 ms. respectively, so that when, say, relay C operates and by suitable biassing makes the tube BB or BA or both non-conducting, the relays A or B will not already have operated. Alternatively the condition of the relays A ... D may be transferred to the register relays after a delay (say 40 ms.), sufficient to ensure that the operated combination is the final one. Gas discharge tubes may be used in place of the thermionic valves shown.
