Title: Means for controlling the supply of liquid fuel to burners for industrial furnaces or other heating apparatus
Inventor: COX RONALD
IPC: F23C5/02
Filed: 1958-06-23
Abstract: 852,418. Liquid fuel burners. LUCAS (INDUSTRIES) Ltd., J. June 8, 1959 [June 23, 1958], No. 19990/58. Class 75(1). A burner removably mounted on a furnace front 27 comprises two separable body parts 2, 3 clamped together by a pivoted yoke 8 and a screw 9, and a pair of fuel valves 13, 15 disposed in the lower body part 3, one valve 13 being a spring-loaded closure valve and the other 15 being a rotatable plug valve. The spindle 20 of the plug valve 15 is detachable therefrom and passes through a bracket 21 fixed to the furnace front to hold the burner in operating position. In this position access to the head 32 of the screw 9 clamping the body parts 2, 3 together is prevented by a hood 31 on the furnace front. Also in this position the spring-loaded closure valve 13 is held in open position by an abutment 19 on the furnace front. To allow the burner to be removed the spindle 20 of the plug valve 15 is turned to closed position and is disengaged from the valve by being pulled downwardly, a key 23 on the spindle entering grooves 24 in the fixed bracket 21. The screw 9 also secures a burner head 4 in the upper body part 2. The fuel passes to the burner head 4 through a detachable plug and socket connection 12 between the lower body part 3 and the burner head 4.

[Class 64 (ii).] A thermal switch comprises a diaphragm a of oblong shape having a guard plate b, acting upon a spring- loaded lever which controls a tilting mercury switch. The diaphragm is corrugated only in the direction of its length and the space behind it is connected by a tube 3 to a vessel containing fluid and subject to temperature changes. The diaphragm acts through a plate c upon an adjustable stop d carried by a lever e pivoted at f. The other end of the lever e is connected by a link g to a pin in a groove in a disc i, carried by a pin j which also carries a mercury switch k. The disc i has two notches m, n engaged by a projection o on a blade spring p. The movement of the lever e is limited in both directions by two adjustable stops t, u, and is loaded by an adjustable spring v. The disc i serves to hold the mercury switch in either of its two positions, and the pressure of the spring p determines the pressure which must be exerted by the diaphragm or by the spring v to move the switch from one position to the other.

Abstract: 1485335 Producing manganese DEEPSEA VENTURES Inc 15 May 1975 [20 May 1974]  20636/75 Heading C7D Mn is produced by reacting an oxide or halide of Mn with a subhalide of a transport element selected from Al, Si or Ti, i.e. AlX, SiX 2  or TiX 2  (where X=halogen), to form Mn and the normal halide, i.e. AlX 3 , SiX 4  or TiX 4 . Fig. 1 illustrates the reaction of MnO with AlX and a flux in reactor 12, removing Mn at 51, AlX 3  to converter 31 and Al 2 O 3  + flux to smelter 24 where they meet a source of carbon (coal, coke, charcoal, tar, graphite etc) to form Al which passes to converter 31 to regenerate AlX with the AlX 3  from reactor 12. To prevent the formation of aluminium carbide in smelter 24, a small amount of Si is added, which alloys with Al. Flux from smelter 24 is recycled together with the AlX from converter 31. When using a manganese halide, Fig. 2 (not shown) an alloy of Mn and the transport element may be produced, which is refined to Mn in furnace (60) by reaction with, e.g. AlX 3 , the AlX produced being recycled to the reactor. A further portion of AlX 3  is reacted with water to produce HX, and Al 2 O 3  which reacts as before to produce Al (as Al-Si) which reacts with a third portion of AlX 3  forming AlX, which is recycled. When pure Mn is produced from Mn halide, the refining furnace (60) is not used. In Examples, Mn 2 O 3  is reacted with AlCl (Ex I), MuCl 2  with AlCl, producing Mn-Al which is refined to Mn by reaction with AlCl 3  (Ex II), and MnF2 with AlF (Ex III). Preferred fluxes for use in the reactor are alkali metal and alkaline earth metal fluorides.

Title: Means for automatically signalling the presence of vehicles provided with overhead electric trolleys whilst moving in a junction section set for the branching route
IPC: B61L13/04
Filed: 1938-07-12
Abstract: 516,893. Electric railways; signalling. SOC. ANON. BREVETTI A. PEREGO. July 12, 1938, No. 20672. , Convention date, July 29, 1937. [Classes 104 (iii) and 105] A signal lamp is lit whilst an electric vehicle with overhead trolley is passing a junction point set for the diverging route. If a second vehicle enters before the first has left the signal continues until the second vehicle leaves. An approaching vehicle effects the energization of a relay O over the trolley contact a, a back contact 1u, winding 2 and a back contact 2u; the closure of front contact lo completes a circuit (effective only when the trolley has moved off the contact a) from the overhead. conductor over back contact 1r2, front contact lo, winding 1 of relay O, winding 1 of relay U, winding 2 of relay O. and back contact 2u, and when contact 2u has changed to its front point the circuit includes the winding 1 of relay O and the windings 1, 2 of relay U. A leaving vehicle closes a trolley contact b or c to energize a relay R2 which opens its back contact 1r2 to drop the relays O, U. The signal lamp L is lit only if the conductor gear has been set for the diverging route, since the lamp relay R3 requires in addition to the front contact 3u a contact 1rb1 which is closed only when the conductor gear has been set to the diverging route by an automatic switch A, B. If a second vehicle approaches before the first has left then the second vehicle at trolley contact a energizes a relay Ra since contact 1u is on its front point. When the first vehicle now leaves at the contact c a relay Y is energized over front contact 1ra, winding 2 of the relay Y and a back contact 2x. The closure of front contact 1y completes a circuit (effective only when the trolley has moved off the contact c) from the overhead conductor over back contact 1rb (closed by the energization of the relay Ra of the mechanically interlocked relays Ra, Rb), front contact 1y, winding 1 of relay Y, winding 1 of relay X, winding 2 of relay Y, and back contact 2x; the contact 2x changes to its front point, whereby the circuit includes the windings 1 of the relay Y and the windings 1, 2 of the relay X. The closure of front contact 1x energizes the relay Rb from the overhead conductor, whereby contact 1ra returns to its back point in readiness to cancel the signal by dropping the relay O; U as soon as the second vehicle at contact c energizes the relay R2 to open the contact 1r2.
