Title: Improvements in or relating to Coal Cutting and similar Machines.
Inventor: HIRST HENRY
IPC: E21C27/18
Filed: 1917-10-30
Abstract: 117,552. Hirst, H. Oct. 30, 1917 Braking-down appliances; coal-cutting machines.-In a longitudinally-movable machine for cutting coal or other minerals comprising wedge means for dislodging the mineral and guiding it on to the floor at the side of the machine or on to a conveyer, the wedge, at the forward end of the machine, has its edge perpendicular and extending from the bed to the roof of the seam. The machine may also be provided with one or more horizontal cutters for over-cutting or undercutting or both and, if desired, also with a vertical cutter. In the form shown in Fig. 6, the wedge 6 is carried by the machine frame a in which a cylinder b is mounted, the cylinder containing a ram c which bears against an abutment d adapted to be held stationary by jacks c. A motor k acts through spur and worm gearing j, g, to drive a pump m which supplies water to the cylinder b to force the wedge into the coal, &c. When the machine has moved a predetermined distance, a chain &c. w fixed to the abutment d actuates a lever s to open a valve t and stop the travel. The jacks e are then released and the ram c drawn into the cylinder by means of a chain passing over a sprocket r and guide-pulleys. A further advance is then made. After cutting the length of the face, the machine is returned by a chain anchored at both ends of the face and engaging the sprocket r. In this form, a jib 6<a> at the front of the machine carries guide-wheels 7 and rubbing plates 8 for a cutter chain 13 driven from the motor k through worm gearing 10. In the formation shown in Fig. 11, the machine is advanced by means of pinion 29 engaging a rack 27 fixed to the abutment d, and carries a vertical cutter chain 16 in addition to the wedge 6 and the horizontal cutter chain 13. In this form, the motor drives the horizontal cutter chain through spur goaring 19, 54 and bevel gearing 55, 56, 58, 59 and also drives a shaft 18 through a pin gearing 19 - - 24; the shaft 18 carries a driving sprocket 17 for the vertical cutter chain and also carries cams 40, 41 which oscillate pawl bars 38, 39 and so rotate ratchet wheels 34, 35, which, through spur gearing 32, 33, drive the pinion 29 to advance the machine; after a given advance, a chain 42<a> acts through a lever 42 to put the pawls out of action. The forward movement of the rack and the return of the machine are effected by a chain passed over a sprocket 47. In a further form, the machine is advanced by the engagement of a sprocket with a chain anchored at both ends of the coal &c. face, the chain being moved on to a second sprocket to effect the return. The machine may be adapted to lift the coal &c. on to a conveyer by means of an inclined plane 60, Fig. 11, mounted on the jib 6<a>.

Title: Scraper conveyor
IPC: B65G19/26
Filed: 1950-06-26
Abstract: 677,302. Endless conveyers. DIRECTIE VAN DE STAATSMIJNEN IN LIMBURG. June 26, 1950. [June 25, 1949] No. 15848/50. Class 78 (i). [Also in Group XXI] A scraper conveyer comprises an endless chain having upper and lower reaches and scrapers so connected thereto that each can move in a plane substantially perpendicular to the plane of the chain from an inoperative position in which it lies substantially parallel with the chain to a position in which it projects therefrom for scraping, and the conveyer is so constructed and arranged that in operation the scrapers are automatically moved so that they lie parallel with the chain whilst travelling along the upper reach and project out from the side of the chain for scraping whilst travelling along the lower reach. In the embodiment shown in which coal is transported from the face along a trough 1 to a conveyer 14, scrapers 7 are connected by pivots 8 to plates 36 welded to a chain 2 passing round sprockets 3, 4 and tensioned by a device 5, and have end portions 9 provided with pins 10 which along the lower run of the conveyer engage between the following chain links 11 to maintain the scrapers perpendicular to the chain as in Figs. 3, 4. As the scrapers travel over the driving sprockets 3 these pins become disengaged from the links 11 and the scrapers, due to their own weight, swing about their pivots 8. Subsequently, as the scrapers commence their travel along the upper run, they are gradually forced by a guide 13, Fig. 1, into a position parallel with the chain. At the return wheel 4 they are swung into a position perpendicular to the chain by their ends 9 contacting a projection 24 controlled by a spring housed in a cylinder 27, this movement being assisted by a cam face 28. As the scrapers leave the wheel 4 to commence movement along the lower run, the pins 1.0 automatically reengage between the chain links 11. The pins 10 may be mounted on the chain links instead of on the scrapers, the pins engaging holes in the scrapers. Alternatively, the scrapers may be kept in their position along the lower run by passing them along a guide constructed in the trough. The upper conveyer run passes over a strip 15, Fig. 3, supported by braces 16 carried by the trough wall 17. These braces 16 also support an air pipe line 18 and a protective casing 19. When the coal is cut mechanically, a coal plough 32 is reciprocated along a guide face 80 by winch ropes 34, 35, the plough being guided by two studs 33 engaging a guide way 31. Specification 677,265 is referred to.

Patent GB-1040417-A (GB)
Title: Recovery of organic isocyanates from crude reaction mixtures
Filed: 1963-04-24
Abstract: Organic isocyanates are recovered from crude reaction mixtures containing them by a process comprising mixing the crude mixture with an inert solvent which dissolves the isocyanate but not the impurities, and separating the two phases so obtained, both phases being liquid throughout the separation.  Preferably, the mixture is first distilled to remove a part of the isocyanate and inert diluent used in the isocyanate-forming reaction and, after the separation into phases, the isocyanate is recovered by distillation.  Suitable solvents for the separation into phases are saturated aliphatic hydrocarbons of 5-10 carbon atoms, benzene, toluene and dioxane.  The isocyanates which may be treated include hexyl isocyanate, tetramethylene diisocyanate, 3,31-diisocyanato dipropyl ether, cyclohexyl isocyanate, tetrahydro-a - and -b -naphthyl isocyanates, benzyl isocyanate, phenyl isocyanate, 3-nitro-4-dodecylphenyl isocyanate, m- and p-phenylene diisocyanates, 1,3,5-benzene triisocyanate and tetrahydrofurfuryl isocyanate.  Others are specified also, and reference is made to the treatment of chlorinated isocyanates. Examples are given of the treatment of toluene diisocyanate prepared in known manner from toluene diamine and phosgene.
