Title: Improvements relating to the supply of fuel to liquid fuel burners
Inventor: APPLEYARD JACK
IPC: F23D11/00
Filed: 1953-09-25
Abstract: 746,068. Supplying liquid fuel to burners. URQUHART'S (1926), Ltd. Sept. 24, 1954 [Sept. 25, 1953], No. 26442/53. Class 75(1). The invention resides in a system supplying liquid fuel and gas, for instance air or steam, to a burner 2 and in a device for carrying out the system. In the system the pressure of the gas acts on one face of a movable spring-loaded partition 10 the other face of which bears against a volume of liquid fuel communicating with the fuel passage in the burner through control means arranged to restrict the flow of fuel towards the burner when the partition is displaced by the gas pressure and to permit rapid retraction of the fuel from the burner when the gas pressure ceases. The system prevents dripping of fuel from the burner nozzle when the burner is shut down. The device comprises a casing divided by the partition 10 into two chambers 7, 9, the chamber 7 having a closure wall having a restricted passage 13 through it for the gradual flow of fuel from the chamber and having a one-way valve allowing non- restricted flow of the fuel into the chamber. The one-way valve comprises a ball 14 resting on a conical seating. The partition 10 is clamped peripherally between the body 6 and cover 8 of the casing and carries centrally a stop member 16 spaced a short distance from the cover. The chamber 9 is connected by a pipe 11 to the compressed air supply line to the burner. When the burner is started the burner air moves the partition 10 against the action of its spring 15 to drive the fuel in chamber 7 gradually through the restricted passage 13, but when the burner is shut down the spring 15 reverses the movement of the partition and fuel is pulled back suddenly from the burner nozzle through the one-way valve.

Title: Improvements relating to digital counting devices
Filed: 1954-09-13
Abstract: 799,772. Counting apparatus. LANDIS & GYR AKT.-GES. Sept. 13, 1954 [Sept. 12, 1953], No. 26449/54. Class 106 (1). An electric counter comprises four binarystages interconnected so as to provide for the counting sequence set out below, and an interpolation indicator consisting of ten glow lamps connected. between the stages so as to be lit in turn to indicate the interpolation numbers 0-9. Each of the four trigger circuits shown diagrammatically in Fig. 1 is regarded as OFF when the left-hand side is conducting. Negative counting pulses on an input line 11 effect the changes tabulated above by virtue of the particular arrangement of communicating lines 12 ... 15. Other connections giving similar results are also illustrated in the Specification (Figs. 4 to 6, not shown). The effect of counting pulse No. 4 is to drive Stage I OFF whereupon, via line 12, Stages II and III are driven OFF and via line 14, Stage IV is driven ON. However, this last change feeds back a negative pulse on line 15 which drives Stage II back to the ON condition. In another embodiment (Fig. 7, not shown) electromagnetic relays are employed in place of the electronic trigger circuits. In both embodiments the indicating glow tubes 0 ... 9 are connected by their upper terminals into the counting circuit with odd-numbered tubes grouped together and connected to one side of the first stage and even-numbered tubes grouped together and connected to the other side of the first stage; the lower terminals of the glow tubes are connected in adjacent pairs to two each of Stages II, III and IV so as to cause a striking potential across an appropriate tube to indicate each state of the counter.

Title: Improvements in gas-blast electric circuit breakers
IPC: H01H33/32
Filed: 1956-08-30
Abstract: 804,401. Gas-blast switches. ALLIS-CHALMERS MANUFACTURING CO. Aug. 30,1956 [Sept. 13, 1955], No. 26574/56. Class 38 (5). [Also in Group XXIX] In a gas-blast switch, means are provided to exert on the blast valve a substantial portion of the force necessary to open the valve, so that the contact operating means only have to provide the remaining portion of the force. In the arrangement shown, the energizing of a solenoid 97 causes an armature 95 to turn a lever 91 clockwise to unlock a pilot valve 84 for operation by the leakage of compressed air past a main valve member 83. The valve member 83 is then operated by the resulting pressure differential and admits compressed air to a pipeline 28. Air from the pipeline 28 acts on a piston 20 to apply to the blast valve 18 the substantial portion of the force necessary to open it. Air from the pipeline 28 also acts on a valve element 33 which opens an outlet port 32 for the supply of compressed air to the contacts " opening " motor 16 and at the same time the element 33 oversets a toggle 36 to position a roller 61 in the path of movement of a cam 60 on the contacts-operating shaft 40, so that as the motor 16 commences to turn the shaft 40, the cam 60 through a lever 37 applies the remaining portion of the force necessary to open the blast valve 18 to the valve 18 which is opened. When the piston 48 of the motor 16 passes a port 59, compressed air is supplied to the underside of a piston 103, the upward motion of which causes the anticlockwise rotation of the lever 91 to close the pilot valve 84. The resulting closing of the main valve member 83 stops the supply of compressed air to the motor 16 and to the valve 33, the blast valve 18 having already been closed by air acting through a port 63 when the cam 60 left the roller 61. Should the solenoid remain energized, the piston 103 is magnetically held in its upper position to prevent any further opening of the pilot valve. The closing of the contacts is effected by a motor 70 controlled by a solenoid-operated valve assembly 69 similar to that described above, no closing blast being provided.

IPC: G21C7/16
Filed: 1947-10-07
Abstract: 869,599. Nuclear reactor control rods. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 7, 1947, No. 26979/47. Class 39(4). In a nuclear reactor, both the fuel and shut-down rods are mounted in vertical cylinders which are inserted into the moderator through channels in the shielding. Both sets of rods may be air cooled and each shut-down rod is urged into the reactor' along its cylinder by compressed air. The escape of radiation from the pile interior, through the channels, is prevented by the radially stepped form of the cylinders which act as plugs. Each shut-down rod is maintained at the upper end of its associated cylinder, away from the core, by a Solenoid which, when de-energised permits the rod to be forced, by compressed air, towards the lower end of the cylinder, inside the core. The cooling air, which flows through the cylinder from the lower to the upper end may be used to return the shut-down rod to its upper position. Indicating switches are operated by the shut-down rods at the inner and outer positions, each rod consists of a steel tube filled with boron carbide powder and the outer cylinder is of aluminium. As shown, the heavy water moderator 11 is enclosed in tank 1 between shields 2 which are penetrated by the tubes 3, 6, and 7. The inner tubes 4 contain uranium fuel rods and have openings 5 for the flow of coolant. Each shut-down rod 14, is contained in the tube 12, 16, 21. With the rod in the retracted position as shown, the piston 13 is held in the electromagnet 17. Upon de-energisation of the latter, pressure fluid is admitted at 18 and the rod 14 is urged downwards into the moderator and into engagement with the buffer spring 20 and the push rods 24 which actuates the indicating switch 25. To cool the rod 14, air is admitted at 22 and flows upwards to the exhaust ports 23. The rods may be raised by increasing the cooling air pressure. Specification 821,931 is referred to.
