Title: Gas burner for pulsating combustion - has valve ensuring simultaneous arrival of gas and air at burner
Inventor: NIEMANN KARL
IPC: F23D14/60
Filed: 1975-10-09
Abstract: The pulsating gas burner arrangement has an externally driven valve in the pipes supplying fuel and combustion air. This burner ensures that fuel and combustion air arrive simultaneously to the burner. Between the fuel control valve (5) and the gas burner (1) is arranged a spring loaded diaphragm valve (6) in the fuel pipeline. The chamber (10) of this valve is connected by a pipe (12) to the pipeline (2) between the valve (3) controlling combustion air flow and the gas burner (1). A commercial gas pressure regulator can be used as a diaphragm valve (6). The diaphragm loading is reversed for present purpose and the chamber (10) connected with atmosphere is used as the working chamber.

Title: Symmetrical carotenoids prodn. - by oxidising polyene triphenyl-phosphine-ylids with singlet oxygen; pref. with triphenyl phosphite-ozone adduct
Inventor: BESTMANN HANS JUEPGEN PROF DR
IPC: C07C1/32
Filed: 1975-11-19
Abstract: In a new process for the preparation of symmetrical carotenoids, a phosphonium salt of formula R(CH=CH C (CH3)=CH) n CH2 P circled positive (C6H5)3.X circled negative (IV) is converted into an ylid of formula R (CH=CH C(CH3)=CH2) nCH=P(C6H5)3 (II), and this isoxidised with singlet oxygen or with agents forming singlet oxygen to give a symmetrical carotenoid of the formula R-(CH=CH-C(CH3)=CH)-nCH=CH-(CH=C(CH3) CH=CH)nR (I). In the formulae, X is e.g. Cl, Br, I or HSO4; n is 0,1, 2 or 3; and R is 2,6,6-trimethyl-1,3-cyclohexadine-1-yl, 2,6,6-trimethyl-cyclohexen-1-yl, 2,6,6-trimethyl-2-cyclohexen-1-yl, 2,3,6-trimethylphenyl, 2,3,4-trimethylphenyl, 2,6-dimethyl-1,3,5-heptatrienyl, 2,6-dimethyl-1,5-heptadienyl, 6-methoxy-2,6-dimethyl-1,3-heptadienyl, 6-methoxy-2,6-dimethyl-1-heptenyl, 3-oxo-2,6,6-trimethyl-cyclohexen-1-yl, 4-hydroxy-2,6,6-trimethylcyclohexen-1-yl, 3-hydroxy-2,6,6 -trimethylcyclohexen-1-yl, 6-hydroxy-2,6-dimethyl-1-heptenyl, 7-hydroxy-2,6-dimethyl-1,5-heptadienyl or 6-methoxy-2,6-dimethyl-5-oxo-1,3-heptadienyl. Process enables polyene alcohols (e.g. vitamin A) to be readily converted via phosphonium salts (IV) and ylids (II) into carotenoids (I) (e.g. beta carotene). Yields are substantially higher than when known procedures are used for the oxidation of (II). In an example, axerophthyl triphenylphosphonium iodie is converted into the ylid and this is oxidised with triphenylphosphine-ozone adduct to give beta carotene in 72% yield.
