Title: Improvements in or relating to the manufacture of low boiling oils and cyanides
IPC: C10G9/40
Filed: 1927-11-21
Abstract: 304,421. Clancy, J. C. Nov. 21, 1927. Hydrocarbons, cracking; hydrogenation, destructive.- Low boiling point oils are obtained by distilling oils of higher boiling point in contact with an alkali metal cyanide e.g. molten sodium cyanide. Hydrogenation of the vapours produced is effected by the ammonia formed during the reaction and also by ammonia and other hydrogenating gases admitted from interior sources. Metallic catalysts e.g. iron, nickel, copper may be added to the reacting materials. The cyanide is regenerated by heating it and the carbonaceous residues with an alkali metal carbonate e.g. sodium carbonate to 800-1200‹ C. in the presence of nitrogenous gases. A retort 1 filled with packing material 2 is heated in a furnace B. Molten cyanide is supplied through a hopper 3 to a trap pot 5 over the edges of which it flows down the retort, the residues being removed through cyanide and oil seals 7, 8, 14. Oils and hydrogenating gases are admitted through pipes 6, 12 respectively and the converted products pass off through a pipe 11. Other cyanides e.g. barium, strontium cyanides or cyanates may be used instead of sodium cyanide and sodium formate or alkali hydroxides and carbonates may be used instead of sodium carbonate. Specification 266,809 is referred to.

Title: Improvements in and relating to gas-blast electric circuit-breakers
Inventor: ROXBURGH ALBERT
IPC: H01H33/32
Filed: 1958-10-09
Abstract: 924,434. Gas-blast switches; electricallytripped switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 18, 1959 [Oct. 9, 1958], No. 32294/58. Class 38 (5). The valves and contacts of a gas-blast circuit-breaker are operated by rotation of a shaft SH produced by movement of a beam TM and a linking mechanism LM, the end LE of the beam being coupled to a piston LP and the end RE to a spring CS, which, in the breaker closed position shown in Fig. 1, is held compressed by the engagement of a roller TR, secured to the end RE by levers LA, with a latch LMB controlled by a tripping coil TC. With the breaker closed the beam end LE is held against a stop ST by the gas pressure in a cylinder LC supplied through a valve CV from the pressure source, and a piston RP, linked to the piston LP by a pivoted lever IL, is depressed in a cylinder RC associated through a pipe CP with the blast produced past the breaker contacts during opening. Energization of the coil TC through switches S 1 , S 2  releases the latch LMB to allow the spring CS to rotate the beam TM about its end LE, movement of the point IP to the position 2, 3 opening the blast valve and breaker contacts via members LM, SH. When blast gas reaches the cylinder RC, the valve CV is closed and the cylinder LC exhausts to atmosphere through a passage EP to allow upward movement of the piston RP to rotate the beam TM about the position 2, 3 of the point IP, thus reloading the spring CS and engaging the beam end RE with the latch LMB. Thereafter, opening of the valve CV and closure of the passage EP raises the piston LP to rotate the beam TM about its end RE to the original position, thus closing the blast valve and the breaker contacts. The switches S 1 , S 2  are mechanically interlocked with the beam TM to prevent energization of the coil TC unless the beam is in the breaker-closed position and to control the closing coil (not shown) of the breaker. For this purpose switches S 1 , S 2  have a set of contacts which is respectively open and closed at the upper and lower positions of the beam end LE. The lever IL may be dispensed with by arranging the piston-rod RPR to directly depress the beam end LE.
