Title: Tension lock-up for thin printing plates
IPC: B41F27/12
Filed: 1961-02-28
Abstract: 911,855. Printing machines. MIEHLE-GOSS-DEXTER Inc. Feb. 28, 1961 [March 7, 1960], No. 7294/61. Class 100 (2). A thin printing plate 16 having turned-over edges 16a, 16b, is secured to a cylinder 15 by plate-securing means housed in a slot 24. The means comprise a series of U-shaped spring elements 26 which are secured in the slot to an L- shaped block 30. The latter is mounted at each end through pips 35, 36 which engage a plate 34 adjustably attached to the associated end of the cylinder 15 by bolts 38 threaded into tapped holes in the cylinder and passed through slots 39 in the plate. Rigidly fixed to the cylinder end is a collar 40 rotatably journalling a screw 41 extending for threaded engagement into a tapped opening 42 in the plate. By turning the adjusting screws 41 at the opposite ends of the cylinder 15 by equal or different amounts the block 30, and hence the spring elements holding the printing plate, may be adjusted either to move the printing plate circumferentially or to skew it. Each spring element 26 has jaws 26d, 26e which in their normal or relaxed position close on each other thereby drawing the printing plate with which they are engaged through the edges 16a, 16b, tightly around the cylinder. In order to release the plate the jaws are forced apart by rotating a shaft 28 which is rotatably mounted in the slot 24 within the spring elements 26 and is formed with a flat 28a such that it has maximum and minimum dimensions " m " and " n." The shaft is mounted in circular openings 44 in the plates 34 and has squared ends 28b received in squared openings cut in control members 45, 46. Rotation of the shaft is restrained between two angular limit positions by engagement of the pin 36, which projects from each plate 34, with the associated member 45 or 46. Such restraint ensures that the shaft is always turned counterclockwise to spread the jaws 26d, 26e. The shaft may be turned by hand through applying a wrench to the squared ends 28b or such movement may be automatically applied through the engagement of a bolt 50 projecting from the member 45 with a stud 51 which is mounted on the associated end of a cylinder such as a blanket cylinder 20 which rotates in contact with the printing cylinder. Such automatic release of the elements 26 from their plate unlocking position, Fig. 7, to their locking position, Fig. 8, ensures that the plate is secured to the cylinder 15 when the adjacent cylinder 20 is holding the trailing end of the plate over the whole cylinder length. The plate securing means may be used to fix paper plates 55 to the cylinder in which case a slot 28d, Fig. 12, is formed in the shaft to hold the trailing edge 55b of the plate. In another embodiment, the spring elements are in two parts, the jaws 26e<SP>1</SP>, Fig. 13, being carried on arms 26c<SP>1</SP> bolted to the block 30<SP>1</SP> whilst the jaws 26d<SP>1</SP> are secured directly to the front edge of the block. A single spring element extending the length of the slot may be used instead of the plurality of shorter elements.

Title: Improvements relating to the treatment of mineral materials with gases
IPC: C04B7/40
Filed: 1939-03-09
Abstract: 526,180. Drying, calcining, sintering &c. apparatus. JORGENSEN, M. VOGEL-. March 9, 1989, No. 7685. [Class 51 (ii)] [Also in Group XIII] In the drying, calcining, sintering or other treatment of materials such as ores and cement by spreading them in a gas permeable layer on drum-shaped grate mounted to rotate about an horizontal axis and passing gases through the grate and the layer of material, the grate is cleaned by forcing a blast of air through it in the opposite direction to that in which the gases flow during the treatment of the material. In the apparatus shown in Fig. 1, and forming the upper part of a rotary kiln, the charge is supplied in the interior of the drum 8 by a jigging conveyer 18, which may be constructed as described in Specification 525,614, and is held in contact with the grate over the greater portion of its periphery by suction as described in Specification 404,018. A shield 15 and baffle 16 prevent the flow of gases through the portion of the grate to the right of the baffle and the release of suction at the upper edge of the baffle allows the treated material to fall into a trough 21 from which it may be conveyed to the main body of the kiln. The grate is divided into a number of sections by longitudinal partitions 9 on the exterior of the drum, and when a grate section registers with the conduit 24 a blast of air from a pressure reservoir 27 is delivered under control of a quick opening valve 26 comprising a stem 43, Fig. 3, carrying piston-like discs 45 controlling the apertures 46. The valve, which is preferably operated automatically in accordance with the rotation of the drum, is moved against the pressure of a spring 44 by air pressure acting on a piston 42 in a cylinder 41 and controlled by a solenoid-actuated valve 38.
Patent GB-560225-A (GB)
Title: Desulphurisation of hydrocarbon oils
IPC: C10G25/11
Filed: 1942-06-08
Abstract: 560,225. Disulphurising oils. SHELL DEVELOPMENT CO. June 8, 1942, No. 7783. Convention date, June 30, 1941. [Class 91] Oils containing sulphur compounds, particularly mercaptans, are purified by contacting them with an acid - activated clay suspended in a high-boiling carrier oil, having a low content of aromatics, at a temperature above the temperature required for flash vapourisation of the oil but below the incipient cracking temperature thereof whereby H2S is liberated. The purified oil and the H2S are separated in vapour form from the liquid clay slurry. If the temperature of reaction is above 585 F., the clay slurry becomes automatically regenerated ready for reaction with a further quantity of oil; otherwise a separate heat treatment at a temperature between 585 and 650 F. is necessary for this purpose. The clays, such as bentonites, are activated by treatment with the free acid or salts containing sulphuric, selenic, phosphoric, phosphorous, and iodic radicals. In one form of treatment, by apparatus such as shown in Fig. II, the oil to be treated enters a heater 1 from a pipe 2 and meets a slurry of clay in a carrier oil conveyed through a pipe 3 by a pump 11. The resulting mixture is heated to from 585 F. to 650 F. and then enters the lower portion of a column 4 in the bottom of which a liquid body of clay slurry is maintained in a state of violent agitation. The upper portion of the column 4 contains bubble trays, and vapours of treated oil leaving by the pipe 5 at the top are condensed by the condenser 6. A portion of the condensate is recycled through the pipe 7 while the remainder passes to the separator 9 where H2S separates. The spent slurry is withdrawn from the column 4 through the pipe 10 and pumped back to the heater 1 where it is regenerated. A certain amount of spent slurry is rim off from the pipe 12 at the bottom of the column 4 while fresh slurry is introduced into the system from the tank 13. In another arrangement shown in Fig. III, the oil enters the bottom of the column 4 from the pipe 20, passing through a preheater 21, if desired. The clay slurry at the bottom of the column 4 is kept at a high enough temperature to flash vapourise the oil stock as it enters the column, being circulated through a heater 24 and pump 23.
Patent GB-579419-A (GB)
Title: Improvements in or relating to the production of tapered polyamide filaments
IPC: D01D5/20
Filed: 1943-05-17
Abstract: Tapered synthetic linear polyamide filaments are prepared by drawing a substantially uniform undrawn filament in such a manner that the drawing tension is varied in a controlled cycle between an upper and lower value, treating the variably drawn filament with an aqueous 20 per cent solution of formaldehyde containing acid catalysts and having a pH less than 3.0, and baking at a temperature between 100 DEG  C. and 150 DEG  C.  The drawn filaments may be cut either before or after the soaking and baking treatment to produce tapered filaments suitable for use as fishing leaders and for the manufacture of paint brushes.  The acid catalysts are acids with ionisation constants of not less than 1.0 x 102 at 25 DEG  C. or water-soluble ammonium, amine or metallic salts of such acids, such as sulphuric, hydrochloric, sulphamic, sulphanilic, sodium hydrogen sulphate, ammonium sulphate, chloride, nitrate, sulphite, bisulphite, thiosulphate, or sulphamate, potassium iodide, potassium chloride mixed with boric acid, calcium chloride, hydroxylamine hydrochloride, aniline hydrochloride, aluminium sulphate and aluminium sulphate mixed with potassium chloride.  The proportion of catalyst employed is preferably from 0.5 to 5 per cent of the weight of formaldehyde solution.  The polyamide filament is preferably quenched in cold water as it is extruded as described in Specification 501,197. The tapering effect may be produced by displacing the filament vertically by a reciprocating pulley as it passes between two horizontally arranged draw points, or it may be drawn between two draw points, one of which is rotated at constant speed, while the other is driven at variable speed by elliptical gears, as in Specification 535,263, or it may be drawn from a roller having a slotted periphery by a roller rotating at higher speed as in Specification 554,203.  The excess of formaldehyde solution adhering to the surface of the filaments is preferably removed and the filaments may be dried at 30-40 DEG  C. prior to baking. Specifications 461,236, 461,237, 534,698 and 565,066 also are referred to.
