Title: Thermoelectric gas burner ignition safety device
IPC: F23N5/00
Filed: 1961-02-08
Abstract: 941,416. Valves. H. VAILLANT, [trading as JOH VAILLANT KOMM. GES.]. Feb. 8, 1961 [Feb. 11, 1960 (2)], No. 4658/61. Heading F2V. In a thermo-electric gas burner ignition safety device, button 21<1> cannot be depressed when knob 18 is rotated to "off" position since button fork 22, Fig. 2, abuts blocking sleeve fork 19. On rotating knob 18 to an intermediate " ignition " position, the button may be depressed because forks 19, 22 inter slide. Between the fork arms 22 and rotating therewith is a locking bolt 23, Fig. 5, which, in the ignition position, has a catch part 24 transverse to a receiving slot 26 in the end of push rod 11 so that depression of button 21<1> opens gas inlet valve 7 via rods 11, 11<11>, bolt 23, 24 and fork 22, permitting gas to pass to the pilot burner. At the same time, rod 27 threaded in bolt 23 and pivoted at 28<1> to lever 28 pivoted at 29, sets armature 33 connected to the end of lever 28 against electromagnet 35 where it is held when the magnet is energized by a pilot burner heated thermocouple, so that button 21<1> may be released but the magnet exerting a small force on a long lever arm holds open valve 7 loaded by strong spring 8 acting on a short lever arm. If knob 18 is rotated fully to " On " position, a knob cam 17 depresses a member 15 abutting flanges 20 carried by sleeve 12 surrounding rod 11 to open main gas burner valve 9, main burner passage 6 also containing a valve 39 opened in response to water flow. If the pilot burner is extinguished, after a short interval the magnet releases the lever, members 27, 23, push rod 11 and valve 7 closes under spring 8. By rotating knob 18 to " Off " when the magnet holds the lever and the pilot burner is alight, the catch 24 leaves the end abutment on rod 11 and enters slot 26 as rod 11 and valve 7 move to closed position.

Title: Improvements relating to blast nozzles and methods of operating the same
IPC: C21C5/46
Filed: 1955-02-16
Abstract: 765,393. Blast nozzles. SIEGERLANDEH KUPFERWERKE GES. Feb. 16, 1955 [Feb. 20,1954], No. 4678/55. Class 51 (1). A nozzle for injecting oxygen under pressure through a blast tube into molten metal is cooled by supplying the oxygen to a chamber surrounding the blast tube at a pressure higher than that required for injection and expanding it in the chamber to the injection pressure. The nozzle shown in Fig. 1 comprises a blast tube 2 surrounded by a chamber 3 to which oxygen at a pressure above that necessary for treating molten metal is introduced through a pipe 4. After expansion in the chamber it passes to the tube 2 through a pipe 5 in which is placed a pressure regulator D. In the nozzle shown in Fig. 2, the chamber 3 has helical guide surfaces 6 which circulate the expanding oxygen around the tube 2 before its introduction therein. The cooling of a nozzle by the expansion of gaseous oxygen may be used in all cases in which nozzles are operated with oxygon or with air enriched with oxygen, e.g. blast and cupola furnace nozzles.

The arms 10 have free ends extending over successive sets of links 11<SP>1</SP> and have dogs or bars 5 for engaging the lengths of timber. The distance between the rear end of an arm 10 and the following dog 5 is greater than the width of the widest piece of timber to be handled and less than the combined widths of the two narrowest pieces of timber. A conveyer 7 transfers the timber from the conveyer 4 to a grading conveyer 9 and operates at a higher speed than the conveyers 4, 9. To prevent one dog 5 from carrying along two pieces of timber, rails 17, adjustably mounted on links 18, ensure that the dogs 5 project above the rails 17 by an amount smaller than the thickness of the timber. A guide member 15, in the form of a spring, is adjustable on a support 16 in accordance with the thickness of the timber. In operation, the dogs 5 can either carry along one piece of timber 12<SP>1</SP> or two adjacent pieces 12, 13; 1211, 13<SP>11</SP>. At the head of the conveyer 4, the piece 13 is lifted by the trailing ends of a set of arms 10 and is returned along the outside of the guide member 15.
