Title: Improvements relating to the manufacture of tanning agents
IPC: C14C3/22
Filed: 1920-06-25
Abstract: Tanning-agents are prepared by heating cyclic hydrocarbons to a temperature below 100 DEG  C. with excess of sulphuric acid to obtain a sulphonated condensation product of resinous character; agents which either enter into or promote condensation, such as formaldehyde, ketones, phosphoryl chloride, or thionyl chloride, may be added.  According to examples, crude naphthalene or anthracene oil are heated on the water-bath with sulphuric acid until sulphonated, a little formaldehyde is then added, and the heating continued until the product solidifies to a resinous mass soluble in water.  The free sulphuric acid in the product may be neutralized by an alkali or other base, and excess of alkali may be added to convert the condensed sulphonic acid into sulphonate. The products may be used in tanning, either alone or in admixture with vegetable tanning-extracts; the vegetable extracts are solubilized and decolorized by this admixture.  Specification 7137/13 is referred to. Reference has been directed by the Comptroller to Specifications 19502/90, 10321/93, 10322/93, 10323/93, 4648/11, 7137/13, and 7138/13, also to 18259/13, 144,657, and 144,677, [all in Class 76, Leather].

Abstract: 1,220,446. Drying photographic materials. KODAK Ltd. 11 April, 1968 [17 April, 1967], No. 17524/67. Heading F4G. In a method for drying a fully processed, i.e. developed, fixed and washed, photographic, hydrophilic colloid layer, which bears an image and is swollen with an aqueous medium, particularly a layer of emulsion on a sensitized, e.g. red-sensitized, spectroscopic plate bearing a hologram-image resulting from laser-beam, e.g. red laser-beam, illumination, and used for projecting a three-dimensional image, distortion of the image and consequentially any projected three-dimensional image is prevented by treating the layer with a liquid composition having a flash point (closed cup) above 7‹ C. and comprising a water-miscible liquid having a boiling point between 100‹ and 200‹ C., and then subjecting the treated layer to conventional drying operations. The liquid composition may comprise 30-100%, by volume, of the water-miscible liquid and the other component may be water and/or a solvent, or solvents. The water-miscible liquid may be an alcohol, preferably diacetone alcohol, or a substituted alcohol such as 2-methylamino ethanol, tetrahydro furfuryl alcohol, 2-butoxy ethanol and butyl diglycol, or a substituted amine such as ethan olamine, diethyl formamide, tetramethyl urea and acetodimethylamide, or an ester such as methyl glycollate and 2- methoxy ethyl acetate. Diacetone alcohol may be used in the form of an aqueous solution, e.g. containing 70%, by volume, of diacetone alcohol. Other suitable alcohols are: ethylene glycol, ethyl glycol, methyl glycol and methyl diglycol. The photographic, hydrophilic colloid layer may be a silver halide-gelatine emulsion layer, e.g. of the Lippman type, which, before or after being developed, has been subjected to a hardening treatment. The photographic hydrophilic image-bearing colloid layer is preferably one which has been developed in a substantially non-tanning developer. The said colloid layer may be supported on material such as a glass plate or a film of cellulose acetate or an aromatic polyester.

Title: Improvements in and relating to automatic car couplers
IPC: B61G3/04
Filed: 1929-06-07
Abstract: 328,151. Jensen, C. A., (Buckeye Steel Castings Co.). June 7, 1929. Couplings, automatic.-In an automatic railway vehicle coupling of the pivoted knuckle type in which the lock 22, Fig. 3, is operated through the medium of a lifter 39, the lifter and lock are detachably connected in such a way that the lifter can be detached only when the lock is in a certain position, but this position of the lock cannot be obtained whilst the knuckle 26 is attached to the coupler head, with the result that the lifter cannot be detached without first removing the knuckle from the coupler head. At its lower end the lock 22, Fig. 14, is formed with an inclined projection 34 adapted to engage under a co-operating part 48 of the tail 27, Fig. 6, of the knuckle to prevent the lock being raised above a certain point, while at its upper end the lock has a cavity 35 with an oblong entrance 36, Fig. 16, and undercut recesses 38 lying in a plane at rightangles thereto. The lifter 39, Fig. 8, is provided at its lower end with trunnions 40 which, in assembling the coupling after the lock has been inserted and raised to its highest position, are passed through the entrance 36, the lifter being then rotated through 90‹ in a direction determined by lugs 45 on the lock to engage the trunnions 40 with the recesses 38. With the lock in its highest position and the knuckle still unattached the lifter is capable of detachment from the lock. To complete the assemblage of the coupling the lock is allowed to drop, an eye 41 on the lifter engaging the upper surface of the coupler head and preventing the trunnions 40 from leaving the recesses 38, and the knuckle is mounted on the coupler head with its tail 27 located over the projection 34 on the lock. The lifter, Fig. 8, has a central portion of I-section tapering between the lines AA, BB, to a cylindrical lower portion. This portion 43 of varying section coacts with a rectangular opening 44 in the coupler head, which is of such a width that, only when the lock is at its highest position, is the section of that part of the lifter in thei slot 44 small enough to allow the lifter to be rotated and thereby detached. Once the coupling is assembled, the lock cannot be raised to this position, and the larger section of the lifter prevents rotation of the latter in the slot 44. When assembled, the coupling acts in the usual manner, that is, after the closing of the knuckle in effecting a coupling, the lock drops to the position, Fig. 6, in which its upper end abuts against the knuckle tail 27: while, for uncoupling the lock is raised, Fig. 3, and the tail 27 swings out through a notch 31 in the lock, the coacting inclined surfaces 34, 48 assisting the opening movement.
