Patent GB-1034934-A (GB)
Title: New tetracycline compounds and manufacture thereof
IPC: C07D311/78
Filed: 1963-10-21
Abstract: The invention relates to derivatives of the hypothetical compound termed "tetracycloxide," to which is assigned the formula <FORM:1034934/C2/1> in which derivatives the hydrogen atom shown is replaced by a dimethylamino or a hydroxyl group.  These derivatives are obtained by treating an appropriately substituted tetracycline with an oxidizing agent.  Specified oxidizing agents are oxygen, an alkali-metal chlorate and hydrochloric acid, mercuric acetate, cupric acetate, alkali-metal periodates, potassium permanganate, N-chlorosuccinimide, alkali-metal peroxides and ferric salts. Oxidation under anhydrous conditions favours the formation of the dimethylamino derivatives and oxidation under aqueous conditions favours the formation of the hydroxyl derivative.  Examples are given of the preparation of 4-hydroxytetracycloxide and 4 - dimethylaminotetracycloxide from 6-demethyltetracycline and of 7-chloro-4-hydroxytetracycloxide and 7-chloro-4 - dimethylaminotetracycloxide from 6-demethyl - 7 - chlorotetracycline. Products specifically claimed are 4 - hydroxytetracycloxide, 7-chloro, 7-bromo- and 7-iodo-4-hydroxytetracycloxide, 4 - dimethylaminotetracycloxide and 7-chloro-, 7-bromo- and 7-iodo-4-dimethylaminotetracycloxide. The products are useful in the synthesis of 4-di-(lower alkyl)amino-6-demethyltetracyclines.  Thus, a 4-hydroxytetracycloxide may be treated with a mono (lower alkyl) amine under reductive amination conditions to yield a 4-dedimethylamino - 4 - mono - (lower alkyl)amino - 6 - demethyltetracycline, which in turn may be treated with a lower alkanol under similar conditions to yield a 4-dedimethylamino-4-di-(lower alkyl)amino - 6 - demethyltetracycline. These properties have bactericidal properties, and in this connection a comparison is made between the properties of 4-dedimethylamino-4 - methylethylamino - 6 - demethyltetracycline and those of 6-demethyltetracycline hydrochloride.

Filed: 1974-09-26
Abstract: 1480818 Automatic control of gas turbines GENERAL ELECTRIC CO 26 Sept 1974 [28 Sept 1973] 41893/74 Heading G3N A compressor stall detection and protection system for a gas turbine engine determines whether the rate of change of compressor pressure exceeds a maximum allowable rate and if so whether the actual change in pressure exceeds a minimum change indicative of a stall when the fuel supply is regulated. As shown, the detected compressor output pressure signal is differentiated and compared with a reference in slope detector 78. If the reference is exceeded the output signal to integrator 98 becomes positive and the signal at the output of inverter 68 is integrated by virtue of resistor 92. The integrator output, which  represents the actual pressure change, is compared with a minimum pressure change signal indicative of a stall in comparator 106 and the output used to fire SCR 126 to cause relay 132 to operate and open contacts 133 to de-energize flow valve 36. The SCR is switched off by operating reset switch 136 either manually or automatically after a time delay. The system is tested by closing switch 79 and then altering the engine throttles to decelerate the turbine when the protection circuit functions to cause SCR 126 to fire.
