Title: Improvements in the manufacture and production of iminopolymethine dyestuffs
IPC: C09B23/16
Filed: 1935-08-28
Abstract: Imino-polymethines are prepared by condensing a -methyleneindolines wherein an aldehyde group replaces one hydrogen atom of the methylene group with primary or secondary purely aromatic amines in the presence of acid condensing agents. The term "purely aromatic amines" comprises amines, the amino nitrogen atoms of which are attached only to aromatic carbocyclic nuclei.  It is advantageous to employ molar proportions of the indoline for each amino group present in the aromatic amine, and the dyes obtained resemble the basic auramine dyes; generally they are water-soluble and may be converted to acid dyes by sulphonation, while in many cases they are suitable for preparing lakes.  In examples 1.3.3-trimethyl-2-methyleneindoline-o -aldehyde is condensed with aniline hydrochloride, p-phenylenediamine in presence of hydrochloric acid, diphenylamine in presence of sulphuric acid, N-(p-ethoxyphenyl)-a -aminonaphthalene, in presence of sulphuric acid and 4.4<1>-dimethyldiphenylamine in presence of phosphorus oxychloride.  The following condensations are tabulated: 1.3.3-trimethyl - 2 - methylene-o -aldehyde condensed with one molar proportion of p-phenetidine, p-nitraniline, 1-aminonaphthalene, 4-aminoazobenzene, p-anisidine, p-toluidine, 4-ethoxydiphenylamine, 3.4<1>-diethoxydiphenylamine, and 4.4<1>-diethoxydiphenylamine; and with a half a molecular proportion of o-phenylenediamine, m-phenylenediamine, 2.4-toluylenediamine, 1.5-naphthalene diamine, 3.3<1>.4.4<1>-tolidine, 3.3<1>-diaminoazobenzene, 4.4<1>-diaminodiphenylmethane, 4.4<1>-diaminobenzophenone, 4.4<1>-diaminodiphenylamine, 4.4<1>-diamino-3.3<1>-dimethoxydiphenylmethane, 4.4<1>-diamino-3.3<1>-dichlordiphenyl-methane, 4,4-diamino diphenyl ether and 4.4<1>-diamino-3.3<1>-dimethyldiphenylmethane; and with one third a molecular proportion of p-leucaniline: 5-methoxy-1.3.3-trimethyl-2-methyleneindoline-o -aldehyde condensed with one molar proportion of diphenylamine, 3.4<1>-diethoxydiphenylamine, p-ethoxydiphenylamine, and N - (p - ethoxyphenyl) - 1 - aminonaphthalene; and with half a molecular proportion of p-phenylenediamine.  The products dye tannin-mordanted cotton red and yellow shades.

Title: Improvements in front-strike typewriting machines
IPC: B41J7/24
Filed: 1924-10-14
Abstract: 235,071. Fairweather, W. C., (Underwood Typewriter Co.). Oct. 14, 1924. Type-lever machines.-Type-levers of equal length are equally distributed in the type-lever segment and are arranged in three groups, namely a middle group and a sub-group at each side, the type-levers of the middle group being normal to the segment and those of each sub-group being arranged to fan outwardly at their free ends, thereby enabling the segment to accommodate a larger number of type-levers than is usual. As shown in Figs. 1 and 3, the type-levers 14 of the central group are guided in equally spaced radial slots 26 cut normally to the segment 17, whereas the type-levers 15 of the two outer groups are guided in radial slots 27 which are skewed or converge rearwardly, causing a corresponding convergence of the levers guided therein. The head portions 28 of all of the outer type-levers 15 are bent at an obtuse angle to provide clearance, and the heads of most of the central group of type-levers are similarly bent. In addition, the head portions 28 of the outer type-levers are twisted relatively to their body portions 29, as shown in Fig. 6, to compensate for the skewing of their guiding slots, thereby ensuring that their types 19 are brought parallel to the plane of writing when actuated. In order that the oblique movement of the outer groups of typelevers shall not cause them to bind upon their fulcrum wire at the back of the segment, the upper ends of the bearing slots which receive the fulcrum wire are bevelled, and the pivotal connections between the ends of the type-levers and the key-actuated bell-cranks are made long enough to allow lateral play of the type-levers. Specification 17856/06 is referred to.

Abstract: 993,030. Masted lift trucks. LANSING BAGNALL Ltd. July 19, 1963 [June 29, 1962], No. 25031/62. Heading B8H. The lifting carriage of a fork lift truck is provided with jaws 37 for gripping part 38 of a pallet when the pallet is raised by the forks 26. As shown, Figs.. 2, 3, the jaws 37 are slidably mounted on rods 40, which are secured to brackets 41 on a bracing plate 29 of the lifting carriage, and are urged apart by compression springs 42. The usual chains 23 for raising the lifting carriage are secured to the pistons of hydraulic piston and cylinder devices, the cylinders of which are secured to the rear of the plate 29 and are connected by hoses to the cylinder of an hydraulic ram 43 pivoted between the jaws 37. The arrangement is such that when the forks 26 are raised into engagement with the underside of the upper deck of a pallet, further upward movement of the chains raises the pistons of the piston and cylinder devices so that hydraulic fluid is forced out of the cylinders into the cylinder 44 of ram 43 until the jaws 37 grip a block 38 secured to the underside of the upper deck of the pallet. Further upward movement of the chains then raises the lifting carriage in the normal way. The forks 26 are slidably mounted on a rod 31 on the lifting carriage and are locked in selected positions on the rod by pins 110 which pass through pairs of holes 111,112 in a bar 28 on the lifting carriage. In a second embodiment, Fig. 5, the jaws 61 have upright portions 62 pivoted on a pin 63 on the rear of plate 29 and are provided with lugs 66 to which the lifting chains 23 are secured. Upward movement of the chains 23 thus moves the jaws towards each other against the action of tension springs 69 to grip the block 38. In a modification (not shown), the jaws are moved towards each other to grip the block 38 by an hydraulic ram controlled by the truck operator, and in a further modification (not shown), the jaws are moved away from each other to engage two blocks on the pallet.
