Title: Improvements relating to coupling devices for railway or other vehicles
IPC: B61G5/02
Filed: 1930-05-12
Abstract: 354,728. Couplings for road vehicles. GOODALL, C. N., Locomotive Works, Darlington. May 12, 1930, No. 14567. [Class 79 (iii).] In a coupling or articulated connection between road vehicles of the kind comprising a draw-bar jointed universally at its ends to socket members on the vehicle frames, the socket members are adapted to be secured in position by means of inclined planes or wedges. In the construction shown in Figs. 1-3, the connection comprises inner and outer hemispherical members A<1>, D associated with the draw-bar A embracing between them a hemispherical socket B, which has tapering flanges b<2> on two sides and is secured in the frame E by wedges F forced between the flanges and abutments el on the frame. The necessary thrust on the wedges is derived by means of nuts f<1> adapted to engage threaded extensions f of the wedges and to have an anchorage against a bridge-piece G, which is passed over the threaded ends I of fixed distancepieces H and secured by nuts i. When it is desired to withdraw the wedges F, the nuts i bridge-piece G and nuts f<1> are first removed, then the bridgepiece is replaced on the distance-pieces H, and finally the nuts f<1> are re-engaged with the remote portions of the threads t so as to exert the necessary withdrawing force. In place of the fixed extensions f on the wedges F, removable extensions J, Fig. 4, may be attachable to either end of the wedges, thus allowing the latter to be inserted from above or below the coupling. In a modification, a hemispherical member on the draw-bar is arranged to swivel between two hemispherical members adapted to be secured by wedges to the vehicle frame. In another modification, Fig. 5, an axially threaded ball B<1> on the end of the draw-bar A is positioned in a spherical member formed by two connectable hemispheres L, L\ between which are secured removable liners N to compensate for wear. In a still further construction the draw-bar is formed with integral spherical ends, each of which works in a three-part spherical socket. All the constructions permit a ready separation of the various parts, the elements secured to the frame being withdrawable, after the wedges are removed, by rotating them until the flange portions, e.g. b<2> Fig. 1, are clear of the abutments e<1>. Specification 141,396, [Class 103 (v), Railway &c. vehicles, Draught &c. appliances for], is referred to.

Title: Improvements in and relating to the direct hydration of ethylene to ethanol
IPC: B01J23/30
Filed: 1949-06-01
Abstract: Hydration of ethylene to ethanol is effected by contacting at elevated temperature and pressure a mixture of vaporous ethylene and partly vaporous water in a molar ratio of total water to ethylene of at least 5, generally 5-20, with an intimate admixture of titania, and tungsten oxide of approximate composition W2O5.  The liquid preferably percolates through the catalyst at a throughput of 0.1-5 1. per 1. catalyst space per hour, at 200-450 DEG , preferably 290-300 DEG  C., and 100-500, preferably 150-350 atmos.  The catalyst, disclosed generally in Specification 650,475, [Group III], comprises the oxides brought into close association by means other than mechanical mixing.  Thus, titania is calcined, mixed with ammonium tungstate, dried, pelleted, and reduced in ethanol (see Group III).  Aqueous alcohol from the converter is let down to atmospheric pressure, ethylene flashed off, cooled to separate further alcohol and impurities, and recycled, if desired.  U.S.A. Specifications 1,873,536 and 1,907,317 are referred to.ALSO:A catalyst for the hydration of ethylene to ethanol comprises an intimate admixture of titania, and tungsten oxide of approximate composition W2O5.  The catalyst, disclosed generally in Specification 650,475, comprises the oxides brought into close association by means other than mechanical mixing.  Thus, titania is calcined at 600 DEG C. impregnated with aqueous ammonium tungstate to give 20 per cent tungsten oxide in the final product, dried, calcined at 450 DEG C. pelleted with graphite, and reduced in ethanol at 300 DEG C. Alternatively, titania is calcined at 400 DEG C., ammonium metatungstate to give 20 per cent tungsten metal in the product added, dried at 120 DEG C. pelleted, and similarly reduced.  The amount of tungsten metal in the catalyst may be 5-30 per cent.

Title: Improvements in or relating to rotary presses
IPC: B30B11/08
Filed: 1966-04-04
Abstract: 1,131,060. Rotating table machines. VUMA, VYSKUMNY USTAV MECHANIZACIE A AUTOMATIZACIE. 4 April, 1966 [14 June, 1965], No. 14799/66. Heading B5A. A rotary pressing machine comprises upper and lower pressing dies that are brought successively between upper and lower pressing dies 8, 9 attached respectively via pivoting levers 6, 7 to opposed hydraulic cylinders 4, 5 mounted along a single axis comprising a pistonrod 3 fixed to the frame of the machine. The working pressure between the discs 8, 9 is adjusted by pumping fluid under a piston 23 in the cylinder 4 and above a piston 24 in the cylinder 5, which forces the cylinders and hence the levers and thereby the discs towards one another when the piston 23 contacts an adjustable stop 2 and the piston 24 a fixed stop 10. If a set pressure between the discs 8, 9 is exceeded they are moved apart, which movement reduces the working space in the cylinders 4, 5 and from which fluid is forced. After removal of the press dies from between the discs, the pressure thereon decreases and as a result of excess pressure in a fluid reservoir 12, the cylinders are once more moved until the respective stops 2, 10 are engaged. A manometer 11 determines the range in which the pressure cylinders 4, 5 may decrease and acts below a certain pressure to switch on an electric motor 19 driving a pump 18. Adjustment of the position of discs 8, 9 in respect of the dies is by raising or lowering the piston-rod 3 by means of a nut 21 by which it is attached to the frame.
