Patent GB-780266-A (GB)
Title: Process for the manufacture of diazoamino-compounds in dry form
Filed: 1954-08-27
Abstract: Diazoamino-compounds are obtained in dry form by subjecting to a rapid drying operation a solvent-containing mixture of a diazo-aminocompound derived from an aromatic diazo compound and an o-carboxyphenyl-amine as stabilizer and the corresponding diazo-compound and free amine used as stabilizer.  During drying the mixture is advantageously heated for only a few seconds and preferably treated in small portions, e.g. as fine droplets. Spray-drying is preferred with outlet and inlet temperatures of respectively 80-100 DEG  C. and 130-180 DEG  C.  Drying may also be effected by applying the cold solution or suspension as a thin layer to a hot roller or moving band.  The products are used in conventional dyeing and printing processes and preparations may be obtained which do not require acid steaming for print development. In examples diazoamino compositions obtained by coupling diazocompounds with free amines so that the resulting compositions contain some of the diazo-compound and free amine are rapidly dried, diazocompounds being obtained from the following amines: 2-methyl- and methoxy-5-chloro- and 4 - nitro - 2 - methyl - 4 - chloro-, 2 - chloro - and 4 - methoxy -, 2 - and 3 - chloro -, 4 - methyl-and methoxy -, 2,5 - dichloro -, 2 - chloro - 5-trifluoromethyl -, 2 - methyl - 4 - benzylamino-5 - methyl -, 4 - benzylamino - 2,5 - dimethoxy-and diethoxy - and 2 - methoxy - 5 - N - diethylsulphonamido - anilines, a  - naphthylamine and 4,41 - diamino - 3,31 - dimethoxydiphenyl and the free amines used are 2-carboxyphenylamino - acetic acid, 2 - methylamino - 5 - sulphobenzoic acid, 1 - methyl -, ethyl -, isopropyl -, n - butyl -, isobutyl - and benzyl - aminobenzene - 2 - carboxy - 4 - sulphonic acids and a  - (2 - carboxyphenyl)-amino - butyric -, propionic -, valeric -, b -methylbutyric- and phenylacetic acids.

Title: Drive mechanism for rotary wing aircraft
IPC: F16H35/00
Filed: 1961-07-21
Abstract: 943,813. Rotary wing aircraft. L. BOLKOW, [trading as BOLKOW-ENTWICKLUNGEN KOMM. GES.]. July 21, 1961 [July 21, 1960], No. 26531/61. Heading B7W. The rotor blades of a rotary wing aircraft, are swung so that an advancing blade is retarded and a retreating blade accelerated, by arms of variable effective length connected to drive means. In Fig. 1, a swash ring 3 on the rotor drive shaft 5 has a non-rotary element 3a supported by pivots 2 from a fixed yoke 1, the common axis of pivots 2 extending transversely of the helicopter. A sleeve 7 keyed to the drive shaft supports an arm 7a for each rotor blade 10, each arm pivotally supporting a lever 8 having an arm 8b from which extends a shaft 12 having rollers 13, 14 engaged between guide surfaces 3b<SP>1</SP>, 3b<SP>11</SP> on the rotary swash ring element 3b. One arm 8b, however, is connected to the element 3b so that the element rotates about shaft 5 with the arm. A double arm 8a of lever 8 is connected by rod 9 to an arm 11 fixed to the blade 10 and extending at right angles to the blade longitudinal axis. The blade is mounted in a lag-lead pivot 18 in the rotor head 15, shown partly in outline by the broken line and mounted by a universal joint 16 on the drive shaft. When the swash ring is inclined on pivots 2 by a pilot's control linkage 4, the lever 8 oscillates an arm 7a, so that the angular velocity of an advancing blade is reduced and that of a retreating blade increased. By making the effective length of lever arm 8a equal to 0.65 of the effective length of arm 11, non-linearity in the transmission of the lag-head movement is stated to be eliminated, so that the movement is sinusoidal. In Fig. 2, the rod 9<SP>1</SP> corresponds to rod 9 of Fig. 1, and is connected to bell-crank lever 24 pivoted on an arm 23a fixed to the drive shaft 5<SP>1</SP>. A link 25 connects lever 24 to a lever 19, pivoted on arm 7<SP>1</SP>a and connected by a block 20<SP>1</SP> to the rotary swash ring element 3<SP>1</SP>b. The remainder of the apparatus is as in Fig. 1, and again, inclination of the swash ring results in lag-lead oscillation of the rotor blades. Devices disclosed for correcting non-linearity in the transmission between swash ring movements and blade lag-lead movements, include non- linear linkages, Figs. 3 and 6 (not shown), and Cardan joints between relatively inclined shafts, Figs. 4 and 7 (not shown).
