Title: Manufacture of O- and P-amidobenzylideneaniline, their Homologues, and their Sulphonic Acids, adn of Amidobenzaldehydes therefrom.
Inventor: IMRAY OLIVER
Filed: 1898-05-07
Granted: 1899-03-04
Abstract: 10,516. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. May 7. Amidobenzylidene anilines and their homologues and sulphonic acids thereof, are produced by the following process :-A nitrobenzyl-aniline, or a homologue thereof dissolved in alcohol, or a sodium nitrobenzyl-aniline sulphonate dissolved in water, is heated with sodium sulphide, with or without the addition of sulphur, on a water bath for several hours. After removal of the alcohol the amidobenzylidene-an;line or similar base is obtained as a yellow non-volatile oil, and the sodium amidobenzylidene-sulphonilate, or similar salt, is obtained in a crystalline form as the solution cools. In these processes o- and pnitrobenzyl derivatives of aniline, of o- and p-toluidine, mxylidene, and of the sulphonic acids thereof, are used. The reaction is represented as follows :- 2 (NO2.C6H4.CH2.NHC6H5) + Na2S # Na2SO4 + 2 (NH2.C6H4.CH : NC6H5). Amidobenzaldehydes. - When the foregoing amidobenzylidene-anilines and their homologues and sulphonic acids thereof are boiled with water they are split up into amidobenzaldehyde and the aniline base or a sulphonic acid thereof. If the benzylidene compounds are treated with sodium bisulphite, the bisulphate compound of the aldehyde is formed, and from this the aldehyde is separated by alkalies. For example, o-amidobenzaldehyde is obtained in the distillate when o-amidobenzylidene-aniline sulphonic acid is distilled with steam, aniline sulphonic acid remaining behind, and p-amidobenzaldehyde bisulphite compound is left in the retort when a solution of p-amidobenzylidene-aniline and bisulphite is distilled in steam, the aniline in this case being distilled off.

Title: Improvements in or relating to Machinery for Welding Chain Links.
Inventor: SCHAR CLOTILDE
Filed: 1900-01-16
Granted: 1900-12-22
Abstract: 997. Schar, C., and Schmid, M. Jan. 16. Welding; stamping.-Making ovallink and like chains. Chains, made up of unwelded links, are suitably heated and passed with an intermittent motion through the machine where the links are welded on their sides and the ridges caused thereby removed by stamping. Figs. 2 and 8 show in plan two machines for performing the operations. As shown in Fig. 2, the welding of two links and the removal of the ridges of two links take place simultaneously by means of stamps. pairs of which reciprocate in planes at right-angles according to the position of the links of the travelling chain. Thus, the stamp 5 in the reciprocating frame 2 welds the link 4 in conjunction with the fixed counter stamp 6. The next link, the plane of which is at right-angles, is welded by a stamp secured to the ascending and descending slide 1 in conjunction with a movable counterstamp below. The ridges are pressed down and thus removed by stamps upon the same slides, the links being penetrated by blocks to allow of this being done. The slides are reciprocated in the one direction by cams and levers, and are returned by springs or counterweights. The chain is forwarded by the intermittent action of the wheel 16, this movement taking place through ratchet and cam gearing. More than two links may be operated upon at one time, if desired, or one link only. In this case, instead of the second slide apparatus would be provided for turning the chain to and fro through an angle of 90‹. In the alternative construction in Fig. 8, the operations of welding are effected by rollers at right-angles to each other, the rollers receiving intermittent movements through bevel gearing. The removal of the ridges takes place by the stamps previously mentioned. Instead of driving the whole machine intermittently, the motion of the welding-rollers may be continuous, and the chain-dragging wheel intermittent. The rollers may be arranged to meet at a given point, having their ends conical and having an angle of 90‹. If apparatus is provided for turning the links, one pair of rollers need be employed.
