Abstract: 306,965. Santoni, E. Feb. 29, 1928, [Convention date]. Stereogrammetric apparatus.-Relates to apparatus for tracing on a plane surface a topographical drawing of an area shown on two photographs taken either from above or on the ground. in which it is not necessary to use objectives identical with the taking objectives, but in which compensation devices are provided to eliminate the effects of distortion of the original objectives. The apparatus comprises two photograph carriers 9 mounted in a frame 1, each provided with a bar 17 by which the photograph 16 is moved under a lens 20. This bar 17 is universally mounted in a ring 3 and is adjustable in length so that the distance between the slide 13 and the axes of the ring 3 is equal to the focal length f of the taking objective. A binocular viewing system is provided having eyepieces 62 and the various points on the photographs are collimated in this system by the movement of a tracer point connected by a pantograph linkage to the sliding carriage 35. In order to utilize photographs taken from the air and the ground the photo carriers may be rotated through 90‹ by turning the frame 1 on the pivots in the support 29. the inclinations of the rods 17 at any given position of collimation corresponds to the viewed direction of the detail observed. In setting the apparatus the distance f is adjusted by operating the screw rings 8 and raising or lowering the support 6. Screws 26, 28 adjust the angular inclination of the photographs to agree with their position during exposure. The carriers 9 may be oriented by the worm 9<1> as shown in Fig. 1. To provide correction for distortion errors in the original objective the upper part of the spherical head 24 of the rod 17, which engages the casing 15 supporting the photograph 16, is recessed as shown so that as the rod 17 moves from its central position the centre of the sphere 24 is caused to be lowered and to describe a curve instead of a straight line. The hollowed part of the sphere 24 bears against a fixed ball bearing 25 and the sphere 24 together with its support 23 moves against the action of springs. For objectives having an opposite distortion the upper part of the sphere 24 is made convex. In operation the eyepieces 62 are set to the inter-pupillary distance of the observer by the screws 59 and the crosswires on the lenses are observed through the optical system contained in the casings 55,56 and sighted on the stereoscopic view presented by the photograpbs 16. The height adjustment is made by the wheel 48 through bevel gearing by rotating the screwed rod 46<1> and raising the carriage 47 supporting the connections 33 with the rods 17. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a description of a tracer point 51, Fig. 12 (Cancelled), connected by a pantograph linkage to the sliding carriage 35 to which the two rods 17 are secured by sleeves 33.

Title: Manufacture of acid wool-dyestuffs of the anthraquinone series
IPC: C09B1/26
Filed: 1934-03-01
Abstract: Acid wool anthraquinone dyes are obtained by reacting a polynuclear aromatic base which is partially hydrogenated with an anthraquinone derivative which contains no sulphonic acid group and either contains in 1,4--1,5- or 1,8- position substituents known to be exchangeable for amino radicles by reaction with amino compounds or contains such an exchangeable substituent in one of these positions beside other substituents in any position, and then sulphonating the products thus obtained. The sulpho groups are believed to enter the partially hydrogenated aromatic radicle yielding acid wool dyes distinguished by the fastness of the dyeing shades to washing and fulling.  In examples: (1) a mixture of leuco quinizarin and quinizarin is condensed with 1- and 2-amino-5.6.7.8-tetrahydronaphthalenes respectively and the products sulphonated in each case (dyes green shades); alternatively 1.4-dichloranthraquinone may be condensed with 2-amino-5.6.7.8-tetrahydronaphthalene followed by sulphonation; if quinizarin admixed with its leuco-body is condensed with 1-amino-4-cyclohexylbenzene and the product sulphonated, a green dye is obtained; (2) 1.5-dichloranthraquinone is condensed with 2-amino-5.6.7.8-tetrahydronaphthalene, 2 - amino - 1.2.3.4 - tetrahydronaphthalene and 1-amino-4-cyclohexylbenzene followed by sulphonation in each case (violet to bluish-red shades); (3) 1.8-dichloranthraquinone is condensed with 2-amino-1.2.3.4-tetrahydronaphthalene and the base so obtained sulphonated (violet shades); (4) 1-methylamino-4-bromanthraquinone is condensed with 2-amino - 1.2.3.4 - tetrahydronaphthalene and the product sulphonated (greenish-blue shades); a similar condensation with 1-cyclohexylamino-4-bromanthraquinone yields a similar dye; (5) 1-amino-2.4-dibromanthraquinone is condensed with 2-amino-1.2.3.4-tetrahydronaphthalene and the product sulphonated (reddish-blue); using instead of this dibromo derivative 1-amino-2-methyl-4-chloranthraquinone a violet dye is obtained; (6) 1.4 - dichloro-5.8-dihydroxyanthraquinone is condensed with 2-amino-5.6.7.8-tetrahydronaphthalene followed by sulphonation (yellowish-green shades).  Samples have been furnished under Sect. 2 (5) of dyes prepared (a) by condensing leuco quinizarin or 1.4-dichloranthraquinone with 2-amino-1.2.3.4.-tetrahydronaphthalene followed by sulphonation (blue shades); (b) by condensing 1-p-toluido-4-methoxyanthraquinine with 2-amino-1.2.3.4-tetrahydronaphthalene followed by sulphonation (bluish green); (c) by condensing a mixture of quinizarin and lenco quinizarin with 5.6.7.8-tetrahydro-a -anthramine followed by sulphonation (green shades).
