Filed: 1934-10-05
Abstract: 431,825. Coking processes; coke ovens. SOC. GENERALE DE FOURS A COKE, SYSTEMES LECOCQ, 215, Chaussee d'Alsemberg, Brussels. Oct. 5, 1934, No. 28612. Convention date, Oct. 25, 1933. [Classes 51 (ii) and 55 (ii)] In the production of semi - coke, the coke oven is heated in two stages, in the first of which the charge is heated so as rapidly to attain a temperature about 700‹ C., in the material adjacent the walls of the coking chamber of, and in the second the heating is reduced so that no substantial amount of the material exceeds 600‹ C. This is done by heating the oven walls by convection and radiation during the first stage, and by radiation only during the second stage. Each combustion chamber 4 has thick walls 2 separated by lateral chambers 9 from the thin walls 3 of the oven chambers 1. Gas and air are supplied to the combustion chambers 4 through conduits 5 and 7 respectively. When the dampers 14 between the exhaust flues 12 and the collecting flues 13 are opened, the hot gases from chambers 4 pass through one of the conduits 10 and chambers 9 to exhaust, the oven chamber between the heating chambers 9 being heated by connection, as well as by radiation from the walls 2. Each coking chamber 1 is situated between two lateral chambers 9 each of which is fed from a combustion chamber on its side remote from the oven chamber. When all the odd chambers 1 are charged, all the dampers 14 below the oven chambers are closed, and it is only when the odd chambers have been heated considerably that all the even chambers are charged, their dampers being opened. All the dampers of the odd chambers are then closed so that these chambers, which have been heated strongly during the first half of their coking period by convection as well as by radiation, are now heated by radiation only. Specification 375,128 is referred to.

Title: A method of improving the taste and smell of fish oils
IPC: C11C3/12
Filed: 1931-10-21
Abstract: Cod-liver and other fish oils are improved in taste and odour without destruction of vitamins by treating with hydrogen in presence of a highly-active non-noble metal catalyst and at a temperature not exceeding 100 DEG  C., not substantially more than 30 litres of hydrogen being absorbed per kg. of oil.  The treatment may be in stages.  The treated oil may be aromatized by adding oil of peppermint, star anise oil, or the like.  For example, 500 gm. of steam-purified cod-liver oil is stirred in an autoclave at 40-50 DEG C. and under 10 atmospheres of hydrogen in presence of 1 per cent of highly active nickel; the oil is separated from the catalyst when 1,7 or 5,0 litres of hydrogen have been absorbed.  The Specification as open to inspection under Sect. 91 (3) (a) is not limited as to the proportion of hydrogen, and describes the preparation of greasy, buttery, or even solid products by hydrogenating at temperatures not considerably exceeding 100 DEG  C.; in an example the process proceeds until 70 litres of hydrogen are absorbed by 500 gm. of cod-liver oil.  This subject matter does not appear in the Specification as accepted.ALSO:Cod-liver oil and other fish oils which have been improved in taste and odour without destruction of vitamines by limited hydrogenation at temperatures not above 100 DEG C. are aromatized by adding peppermint oil, star anise oil, or the like.
