Title: An Improved Mechanically-stoked Furnace.
Inventor: HOFMANN ALFRED
IPC: F23K3/08
Filed: 1918-08-15
Abstract: 126,547. Hofmann, A. Aug. 15, 1918. Graces; mechanical stoking.-Two or more travelling grates having transverse bars with their free edges in step form are arranged one above the other so that each lower grate receives the fuel from the one above it, all the grates being adapted to allow air freely to pass through them. The lower grates are preferably driven at lower speeds than the higher. The installation shown comprises a fuel hopper 1 with a feed conveyer 2, an upper inclined chain grate 5, a lower horizontal one 6, and an ash conveyer 35.' An adjustable flap 4 regulates the thickness of the fuel layer on the grate 5, and a seal 7 consisting of hanging flaps prevents undue admission of air at the end of the grate 6. The side plates of the furnace above the grate level may be air or water-cooled. All the moving parts are driven from a crank-disk 11 by a rod 12 which actuates the pawl 14 of a ratchet wheel 16 on the shaft 15. The shaft drives the grate 5 by means of a worm and worm wheel and also actuates the feed and ash conveyers 2 and 35 by means of gearing. The lower grate is driven, preferably at a reduced speed, by worm and ratchet gearing actuated by a rod 27 connected to the lever 13 of the pawl 14. The speed of the mechanism is controlled by the boiler pressure through a piston in a cylinder 19, which actuates, through a lever 23 and links, a mask 17 which varies the effective stroke of the ratchet pawl 14. A similar mask 17<a> is provided on the driving gear of the lower grate, and the two are connected to move together by a rod 28, adjustable in length so that the relative speeds of the two grates may be varied. The lever 23 also actuates a damper 26 controlling the air supply to the grate. In a modified form with three travelling grates the second and third are upwardly inclined at a slight angle, and the third is driven in the reverse direction to the first and second.

Title: Process for the production of screen negatives for producing photo-mechanical printing surfaces
IPC: G03F5/00
Filed: 1928-05-14
Abstract: 316,364. Gill, H. A., (Amira Trust). May 14,1928. Photo-mechanical printing-surfaces; developing. -A screen negative on a transparent base from which a printing-surface is to be made, is produced by exposure through a screen and in the form of hardened silver dots with no soluble gelatin adjacent the base, and the dots of the image are then modified by intensification or reduction by ordinary photographic methods. By one method a dry plate is exposed through the base using a half-tone screen, and developed with a hardening developer, or developed and treated with a reagent to harden the gelatin in the presence of the exposed silver image, prior to a wash-out treatment to remove the unhardened gelatin. The image is not fixed with hypo, and to induce solubility of the unexposed gelatin the negative is immersed for a short time in potassium meta-bisulphite. In order to prevent the production of very high dots, the emulsion may have colouring-matter in it : alternatively the latent image before development may be treated with bromine-iodine tincture, or copper chloride, to which alcohol may be added. To prevent the residual halogen-silver in the image disappearing by a treatment with Farmer's reducing agent a very thin layer of silver iodide (with or without silver bromide or chloride) is deposited on the image by bathing it in a dilute solution of iodine in potassium iodide to which potassium bromide or chloride may be added. Any unreduced silver remaining may alternatively be blackened by developer. To use emulsion on opaque bases, (e.g. bromide paper), if the base is permeable the emulsion is squeezed on to a glass plate after or before exposure, and developed and treated on the glass plate : but if the base is impermeable, the paper is exposed, developed and the unexposed gelatin removed prior to transfer and subsequent treatment.
