Abstract: 228,937. British Thomson-Houston Co., Ltd., (Assignees of Hull, J. I.). Feb. 9,1924, [Convention date]. Alternating - current commutator machines; improing commutation, auxiliary means for. - The secondary member of a polyphase induction motor is provided with a commutator exciting winding 6 inductively coupled with the primary winding 1 and directly or indirectly connected to the primary supply, and a closed secondary winding 5, the two windings being located in slots at different radii. As shown, the commutator brushes 7 are fed at a reduced voltage from taps on the primary winding through resistances 11. Alternatively, the exciting winding may be fed from a separate winding in the stator slots or from a shunt or series transformer in the line 2. In the latter arrangement, the transformer and exciting windings are designed to carry part of the energy current. The commutator winding is preferably located at a smaller radius than the secondary winding, but the starting torque may be improved by interchanging the positions of the two windings. The slots of the rotor windings are interconnected by a narrow slit, Fig. 2, and to improve commutation, strips of resistance material 13 may be inserted in the slits, or the commutator leads may be connected together by high-resistance conductors. The windings 5, 6 may be placed in the same slots.

Filed: 1952-02-18
Abstract: The invention comprises 1:5 naphthyridine derivatives having alkoxy in 6-position, alkyl in 2-position and hydroxy in 4-position.  They may be obtained by the reaction between a 6-alkoxy-3-amino-pyridin with an ester having, in one tautomeric form, the formula XO - CR1 = CR4.COOY in which X and R1 are H or an alkyl group, R4 is H or the group COOY and Y is an alkyl group, whereby a b -pyridylaminoacrylic ester is produced, and ring-closing by elimination of alcohol, hydrolysing the carboxylic ester group produced, when present, and decarboxylating if required.  The 4-halogen derivative may be obtained by the action of known halogenating agents on the 4-hydroxy compound.  In examples 6-n-alkoxy-3-aminopyridines are condensed with ethylacetoacetate- or ethoxymethylene malonic ester, to give the corresponding b -(6-alkoxy-pyridyl-3)-aminocrotonic ester or b  - (6 - alkoxypyrid - 3 - ylamino) - a  - carbethoxy acrylic ester, which products are cyclized by heating, hydrolysed if required, decarboxylated also if required and converted into the 4-chlor-1:5 naphthyridines having the 6-alkoxy group, to correspond, by means of POCl3.
