Title: Improvements in and relating to the low-temperature carbonization of coal and other materials
IPC: C10B57/06
Filed: 1934-04-23
Abstract: 437,033. Coking processes and apparatus. WINZER, C. B., 63, Sudbrooke Road, Balham, London. April 23, 1934, No. 12213. [Classes 51 (ii) and 55 (i)] In the low-temperature carbonization of coal or other carbonaceous materials such as peat or wood, the unbriquetted charge in its natural state is heated while covered with a powdered refractory material such as cement powder, sand, or chalk. The retained pitch forms a shiny coating on the resulting carbonized pieces. Suitable apparatus comprises an externally heated cylindrical retort 13 divided by a perforated partition 18 into two chambers. The carbonaceous charge mixed with cement powder is fed into the lower chamber, and, after the heat treatment, the retort is rotated so that the lumps of the charge are retained on the partition and removed while the powder falls through and is used again in a subsequent operation. Fig. 4 shows a horizontal oven enclosing the charge which is in a tray 35, and surrounded by a heating jacket 32 fed as shown with hot gases from a flue beneath the oven. A chimney 33 leads away the hot waste gases and an outlet 36 is provided for the distillates. The apparatus shown in Fig. 2 may be used for separating the lump coke from the powder. A tunnel oven, Fig. 5, may be used in which trays 44 containing the charge are surrounded by the powdered material which is introduced through a hopper 45, surplus powder falling into a chamber 47 and being returned to the hopper. A further supply of powder is fed through hopper 51 and acts, as in the first case, as sealing means. The trays 44 are fed continuously through the oven which is externally heated by the jacket 42, and the distillates are withdrawn through outlets 49.

Title: Improvements in type bar actions for typewriting machines
IPC: B41J7/02
Filed: 1920-05-03
Abstract: 167,269. James. R. W., (Remington Typewriter Co.). May 3, 1920. Type-lever actions.-In actions comprising sublevers having pin-and-slot connections with the key-levers and the type-levers, side strain is avoided by pivoting each sub-lever 8 and its corresponding key-lever 25 in the same plane and offsetting the connecting-arm 24 of the key-lever so that the pin 23 on the arm 24 engages the slot 22 in the arm 8a of the angular sub-lever in the plane of movement of the levers. The sub-levers at or near the centre of the system also have the pin at the upper end, engaging the slot in the type-lever, located in the plane of moveement of the key-lever. Noise due to side strain is thus reduced, and the slots in the guide combs of the key-levers can be made narrower to avoid rattling of the key-levers in the combs. Means is also provided for firmly seating the pivot wire 17 of the sub-levers to avoid rattling of these parts. The pivot wire 17 is seated in the slotted crossbar 10 in a groove 13 having parallel side walls 14, 15 and an inclined bottom wall 16, and is clamped against the bottom wall by means of a plate 18 having along one edge fingers 20 extending into the groove 13 and engaging the pivot wire 17 at intervals throughout its length. The plate 18 has a rocking adjustment about a fulcrum formed by a flange 19 on the outer edge, and is positioned by means of a number of screws 21 at intervals along its length. The ends of the groove 13 are closed by screws which can be removed to permit displacement of the pivot wire for removal of one or more of the sub-levers.

Abstract: 541,671. Printing-surfaces. ADDRESSOGRAPHMULTIGRAPH CORPORATION. July, 30 1940, No. 12354. Convention date, Jan 4. [Class 100 (ii)] Planographic printing plates, such as described in Specifications 493,135 and 496,421, and comprising a printing face of cellulosic material secured, e.g. by a waterproof adhesive, to a flexible backing sheet which may be impregnated with a waterproof adhesive, have the printing image prepared thereon in a waterimmissible ink-receptive material which will immediately adhere to the cellulosic material without the necessity of heating and which is resistant to displacement by the inking or damping rollers of the printing machine. The suitability of an image forming material may be determined by forming an image in the material upon a plate of the character described in Specification 541,672 in which the cellulosic printing face has a lateral water-diffusion rate of from 20 to 30 millimeters in four hours. The plate is then immersed in a bath of the usual acidic dampening solution and while immersed, a roller charged with lithographic ink is passed twice over the image. The charged roller is then passed thirty times over a part of the inked image at right angles to the direction of the first passes. If the material is satisfactory no substantial difference in appearance between the inked and reinked parts of the image should be observable. Many suitable materials are specified comprising oil-soluble dyes, gums and resins, pitches, vegetable oils, synthetic resinous substances, insoluble metal soaps, and waxes. Some of these may be used directly as printing inks, lithographic crayons or for impregnating typewriter ribbons, while others may be rendered suitable by exposure to ultra violet light.
