Title: A process for the manufacture of organic nitrogen-containing compounds
Inventor: KT IAN HEILBRON
IPC: C07C237/00
Filed: 1948-01-26
Abstract: Amides of the formula <FORM:0641909/IV (b)/1> are obtained by reacting a compound of the formula <FORM:0641909/IV (b)/2> in a basic medium with a compound of the formula R4.NH.Y and acidifying the product; R1, R2, R3 and R4 are the same or differen and are hydrogen or a hydrocarbon residue, and Y is the complement of an amino acid or peptide or functional derivative thereof such that the group R4.NH retains its basic function unimpaired.  In particular, the compound R4.NH.Y may be written as <FORM:0641909/IV (b)/3> where R5 and R6 are the same or different and are hydrogen or a hydrocarbon residue and Z is a carboxyl, ester, amide, substituted amide or nitrile group.  R3 with either R1 or R2 may form a ring and Z may itself be a polyamide or peptide group.  Preferably, of the pairs R1, R2 and R5, R6, one of each pair is hydrogen, R2 is hydrogen, methyl or phenyl, and the compound R4.NH.Y is a derivative of glycine, glutamic acid or tyrosine.  The group Y-N= in the product may be derived from glycine, tyrosine, glutamic acid, tryptophane, ornithine, methionine or phenylglycine.  The reaction is believed to take place with the intermediate formation of a salt of a dithiocarbamic acid with the base used, i.e. <FORM:0641909/IV (b)/4> where M is the base (inorganic or organic).  Tertiary organic bases such as triethylamine and triethylphosphine are suitable, or alternatively two or more molecular proportions of the compound R4.NH.Y may be used.  On acidifying the reaction mixture, the dithiocarbamate decomposes into the desired amide and carbon disulphide.  In the examples, 2-thio-thiazolone is reacted with (1) glycine ethyl ester; (2) glycylglycine ethyl ester; (3) glycylglycylglycine ethyl ester; (4) triglycylglycine ethyl ester; (5) phenylalamine methyl ester, and (6) tyrosine methyl ester; 4-methyl-2-thio-thiazolone is reacted with glycine and with diethyl glutamate, in the latter case the product being isolated as its p-tolylthiocarbonyl derivative by treatment with p-tolylthiocarbonyl chloride; 4-phenyl-2-thiothiazolone is reacted with glycylglycine ethyl ester.  It is stated that tolylthiocarbonylalanylglutamic di-ethyl ester may also be prepared from tolylthiocarbonylalanine ester by conversion into the acid chloride (via the free acid) and treatment of this with diethyl glutamate.  2-Thio-thiazolone is obtained by treatment of the compound <FORM:0641909/IV (b)/5> with mineral acid. 4-Phenyl-2-thio-thiazolone is produced by acidifying an aqueous solution of a dithio-carbamate of the formula <FORM:0641909/IV (b)/6> where M is an inorganic or organic cation.

Abstract: 590,735. Fluid-pressure servomotorcontrol systems. BELL AIRCRAFT CORPORATION. Feb. 1, 1945, No. 2559. Convention date, June 14, 1944. [Class 135] [Also in Group XXXIII] In a helicopter with an upright rotary shaft 17 carrying blades 10 the pitch of which is controlled by the pilot through a universally mounted control member, the latter is connected to the blades through a servomotor comprising a control valve actuated by the control member to supply pressure fluid to motors coupled to the blades. The blades 10 are mounted in a hub 12 pivoted to a gimbal ring 14 which, in its turn, is pivoted to a ball head 16 so that the plane of rotation of the blades can tilt universally about the top end of the shaft 17. The latter is driven by the engine 22 and the angle of incidence of the blades is changed by vane-type servomotors 25 controlled by a spool valve 32 carried by and rotating with the shaft 17. Pressure-fluid to actuate the servomotors is supplied by an engine-driven pump 40, and the servomotors are connected in series so that the fluid expelled by one vane constitutes the actuating fluid for the opposite vane. The actuating member for valve 32 is a ring 50 constituting a, track for a shoe 46 carried by the valve, and when the ring is tilted, the blades will change pitch cylically as the stem 17 will carry the valve round the track. Ring 50 has a universal tilting movement as it can rotate about an axis 52 on a further ring 54 which is pivoted about an axis 56 at right angles to axis 52. The position of ring 50 is also determined by an automatic pilot 80 through links &c. 67, 68, the automatic pilot comprising paired gyroscopic devices detecting pitching and rolling of the aircraft. Manual control of the pitch of the blades is given by levers 82, 84, or a single universally pivoted lever, acting through the gyroscopes.

At an output S these words are clocked out serially under the control of a circuit including a clock-pulse generator G, a divider Tn, a flip-flop F and a differentiator D, the output from S being fed back over an inverter I to an input D of the shift register SR, the arrangement being such that the composite output signal delivered to the transmission channel US is constituted by a serial word W 1 corresponding to the parallel word Wp followed by the inverse W1 of the word W1 (Fig. 1, not shown). At the receiver, Fig. 3, the composite signal is applied to the input D of a second shift register SR and to one input of an inverting XOR gate EO the second input of which is connected to the output S of the shift register. A control circuit including a clockpulse regenerator TR, a divider Tn, a first flip-flop F1, a differentiator D and a synchronization decoder SD is provided, and the arrangement is such that the gate EO functions to compare the part W of the received signal with its inverse W1; if the comparison is satisfactory the output from the gate EO is effective through the medium of a circuit including two AND gates G1, G2 and a second flip-flop F2 to cause the data to be transferred in parallel form from the shift register SR to a receiving register UR. If the comparison is not satisfactory the circuit G 1, G2, F2 acts to block the reception of data by the register UR. The transmitter may include pulse width or pulse position modulation circuitry the receiver being modified accordingly, and such embodiments are described with reference to Figs. 4 to 6 and 7 to 9 (not shown).
