Title: Process for preparing methine dyes
IPC: C09B23/14
Filed: 1951-10-19
Abstract: A dye of the general formula <FORM:0684386/IV (c)/1> wherein R, R1 and R2 are lower alkyl groups, is prepared by heating together substantially equimolar amounts of a compound of the formula <FORM:0684386/IV (c)/2> and a compound of the formula CN-CH2COOR with an amount of an alkaline catalyst sufficient to cause the condensation to go to completion, in the absence of a solvent, at a temperature sufficient to maintain the starting materials and reaction product in a liquid condition until the condensation is completed.  In example 1, a dye is prepared by adding piperidine to warm p-diethylaminobenzaldehyde and then ethyl cyanoacetate dropwise, and stirring with heating.  The dye may be milled with "Flotite" Dry, Aquarol SO, and water to give a product for dyeing.  In example 2, the procedure is similar, using methyl cyanoacetate.  The aldehyde may also be p-dipropylamino-, p-dibutylamino-, p-methylethylamino-, or p-methylbutylamino-benzaldehyde, and the cyanoacetate may also be propyl or butyl cyanoacetate.

Filed: 1936-09-14
Abstract: 481,449. Retractable aircraft undercarriages ; hydraulic transmission of power. DOWTY, G. H. Sept. 14, 1936, No. 25042. [Class 4] [Also in Group XXIX] The operating jack or jacks of retractable aircraft undercarriages comprise resilient means adapted to store energy during retraction and expend it during extension. As applied 'to jacks 1, 1A, Fig. 1, forming elements of a folding undercarriage member, the jack cylinders have end fittings 2, 2A for pivotal connection to the aircraft structure and an undercarriage leg, respectively. Cylinders 1, 1A are interconnected by links 3, 3A pivoted at 5A to a triangular frame 5, to the remaining apices of which are pivotally connected piston rods 7, 7A. Frame 5 is built up from laterally spaced plates bored at 5B, Fig. 2, and carrying pivots 6 integral with rods 7, 7A. The latter are hollow throughout their length, the bores registering with axially bored passages in pivots 6. Thus pressure fluid admitted at 10 flows through piston rod 7, pivot 6, ducts 5B, the second pivot 6 and piston rod 7A to the working space of jack 1A. Equal effort is thus exerted by both jacks. Between the piston heads and cylinder closure members 9, are fitted helical springs 11 assembled under initial compression. In the down ' position of the undercarriage the piston heads make contact with the cylinder heads in order positively to transmit compression loads in the strut. The strut may in working position be slightly bent so that the compression forces of the springs 11 have a lateral component tending to prevent collapse of the struts. The effect of the springs may be augmented by compression of air within the cylinder space. According to a modification the jacks may be double acting. Specification 442,133 is referred to.
