Title: Control apparatus for fluid fuel buring apparatus
IPC: F23N5/00
Filed: 1952-09-30
Abstract: 735,762. Electromagnetically-actuated valves. MILWAUKIE GAS SPECIALTY CO. Sept. 30, 1952 [Oct. 4, 1951; June 9, 1952], No. 24469/52. Class 135. [Also in Groups XI, XIII, XXXV and XXXVII] A valve 13, Fig. 1A, controlling the flow of fuel to a main burner is opened against spring action by an electromagnet 27 energized by a thermocouple heated by a pilot burner flame. The electromagnet 27 is housed in a cover 25 secured to the top of the valve casing and comprises a coil 28 wound around a pair of magnetically permeable posts disposed between a common pole piece 30 and two separate pole pieces 31. An armature 34 is pivoted by pointed screws 35 engaged in bearing recesses in a fixed bracket 32 and is held in operative position by an angularly disposed screw 35a, Fig. 5, passing through a slot 34a in the armature and threaded into the bracket. The valve 13 has a rubber facing 13a for presentation to the valve seat 14 and is secured by a ball and socket joint to a valve stem adjustably connected to the lower rigid end of a phosphor bronze arm 36 which at its upper end 36a is secured to the armature by screws 36c. This upper end 36a is looped and cut away centrally to provide spaced flexible spring sections 366 which are in alignment with the pivot screws 35 and form a pivot axis for the remainder of the arm 36. The valve is biased to closed position by a spring 39 extending between the fixed bracket and the arm 36. Initial movement of the armature towards the electromagnet does not cause movement of the valve 13 but instead causes bending of the spring sections 36b of the arm 36 until the armature has moved nearer to the electromagnet when the valve opens with snap action. In order to provide an air gap between the armature and the pole pieces of the electromagnet in the attracted position of the armature a stop member 160 extends between the coils 28 and carries an adjustable screw 161 which coacts either directly with the armature or with a spring 162 secured to the armature. The fuel supply to the pilot burner heating the thermocouple for energizing the electromagnet 27 is controlled by a valve member 100, Fig. 8, coacting with a valve port 81 in an internal wall 80 separating an inlet chamber 82 from an outlet chamber 83 in a valve body 23. The valve member 100 is mounted on a stem 97 adapted to reciprocate through the end wall of a housing 85 containing a U-shaped electromagnet 86 and an armature 89 slidably mounted on the end of the valve stem. The valve member 100 is biased to closed position by a member 106 comprising spring fingers co-operating with the valve member and the end wall of the housing 85. The valve is opened by pushing inwardly a spring-returned reset stem 97<SP>1</SP> so that the end 97<SP>11</SP> of the reset stem pushes the valve member 100 off its seat. The electromagnet 86 is energized by the thermocouple heated by the pilot flame and holds the valve in open position after the reset stem has been released.

Patent GB-245336-A (GB)
IPC: G03C7/06
Abstract: 245,336. Weisz, H. May 13, 1925. Colour filters. - For the purpose of ensuring that the glass plates for composite light filters can be combined into correct filters the quantity of colouring components added to the liquid glass in the process of manufacture is such that with a thickness of glass of 2 mm., the shade of colour agress with that of a layer of glass of a normal filter. This enables such glasses to be ground to a thickness of 2 mm., a thickness which renders negligible the influence of grinding inaccuracies on the correctness of the filter. In making a composite filter from such glasses ground in the usual manner they are combined so that a layer of glass below the correct thickness is combined with a layer of glass above the correct thickness. Coloured gelatine filters may be placed between two coloured glasses made as above.
