Coal-cutting machines. -- A coal-cutting machine of the swingable cutter jib type is provided with a haulage drum mounted on a horizontal longitudinal axis and adapted to bo clutched to a power driven shaft and in operative connection with an independent adjustable brake adapted for resisting unwinding. In the cutter chain machine shown, the shaft of the motor has a clutch member automatically engaging a companion clutch member 7, Fig. 5, and may be removed from the machine without disturbing any part thereof: the clutch member 7 drives the vertical spindle 12 through spiral bevel gears 14, 13 held in engagement by rollers 18. The spindle 12 may be coupled to the cutter chain sprocket 19 through sleeve 21 by a, pin clutch 22 controlled by levers 24, 25 and also carries a worm 32 driving a countershaft geared to a longitudinal shaft 37, Fig. 3, which drives the haulage &c. mechanism. The cutter jib is adjusted by means of the haulage rope and is locked by a pin. The shaft 37 drives through spur gear 38, 39 a shaft 40 carrying multiple disc clutches 49, 50 controlled by hand wheel 61 and pins 63 and by hand wheel 59 and pins 52<a> respectively. Cable drums 41, 42 may be connected to the driven members 47, 48 of the clutches 49, 50 respectively by pin clutches 51, 52, whereby either drum may be used to haul the machine or, by adjusting the disc clutches to permit slip, to resist movement of the machine; alternatively either drum may be used to resist movement of the machine by disconnecting the pin clutch 51 or 52 and controlling the drum through a screw operated band brake 81 or 82, on the elongated hub of a pinion 77 or 78 loosely supported by the shaft 37 and engaging a gear 75 or 76 on the drum. Either drum may be driven at low speed from the shaft 40 through gearing 64, 65, countershaft 66, clutch 69 or 70 and gears 67, 75 or 68, 76. Guide pulleys 85 - - 88 are provided for the cables 43, 44 while when the machine is to be used for short-wall working, a bracket 90, Fig. 4, carrying a guide pulley 89 is attached to the gear casing 16.

Title: Improvements in the decomposition of gaseous or vapourous hydrocarbons by means of water vapour
IPC: C01B3/36
Filed: 1927-02-11
Abstract: 265,989. I. G. Farbenindustrie Akt.- Ges. Feb. 11, 1926, [Convention date]. Right to Patent relinquished. Oil gas.-Hydrocarbons, or gaseous mixtures containing them, are decomposed into hydrogen and carbon monoxide by means of water vapour, with the addition of air or oxygen if necessary, and the highly heated gases thus obtained are cooled by water either directly or indirectly, thereby condensing the water vapour in the gases and heating the cold water which is then brought into direct contact with fresh gases containing hydrocarbons to be subjected to the reaction. The resulting gas mixture thus charged with water vapour is introduced into the decomposition chamber after receiving, if necessary, a further addition of water vapour. If pure hydrogen is to be produced, the gases from the decomposition chamber, after an addition of further quantities of steam or water, if necessary, are passed over a catalyst, such as an activated iron-chromium compound, to convert the carbon monoxide and water vapour into hydrogen and carbon dioxide, the latter and any residual carbon monoxide being eliminated. The hot gases issuing from the apparatus in which the carbon monoxide is converted may also be used for the production of hot water which is applied to humidifying fresh gases containing hydrocarbons. Specification 12978/13, [Class 1 (i), Chemical pro cesses &c.], is referred to.

Abstract: 937,108. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Jan. 19, 1962 [Feb. 4, 1961], No. 4284/61. Class 40 (4). In a large PABX in which a calling subscriber by dialling a particular digit gains access to a manual board MB by way of a call-assistance relay set ACRS, each group of 100 line circuits ELC is served by an individual assistance-call finder and marker COFM which provides the identity of the calling line, and all the circuits COFM and all the assistance relay sets ACRS are interconnected by a common identity signalling cable which is assigned to the circuits COFM in succession by a distributer COMD. When an assistance relay set ACRS is seized over the O level of a group selector GS a start signal is fed over a vertical bank to the appropriate circuit COFM, and a finder therein hunts for a marking passed back from the group selector to the relevant line circuit ELC. As a result characteristic code markings are applied to the leads of the signalling cable under the control of the distributer COMD, only the seized relay set ACRS being conditioned to receive such markings. The calling line is extended to the manual board MB by way of a connect circuit CC, which besides lighting a calling lamp seizes a position display relay set PDRS, and the identity of the calling line stored in the relay set ACRS is transferred thereto under the control of a distributer PDD in the same way as it was transferred from the circuit COFM. The call may be set up to an exchange line EL if necessary via a relay set XARS. The circuits of ACRS, COFM and COMD are described with reference to Figs. 3 ... 7 (not shown).

Openings 8 are formed in the plate for accommodating a spinneret assembly 9. The components 4 contain ducts for the spinning melt, the components 5 contain spinning pumps, and the components 6<SP>1</SP>, 6<SP>11</SP> and 6111 form a heat-conducting bridge 6. All these components bear directly on the smoothly machined upper surface of the plate 7 and consequently heat is readily conducted to them. The components 3 to 5 are covered by the heat bridge 6 to prevent heat being dissipated upwards. The complete spinning apparatus 2 is enclosed by a layer of insulation 10 which is provided with cut-outs below the openings 8 and above the component 3. In order that the component 3 containing the spinneret plates 9 can be easily replaced from above, the heat-conducting bridge 6 is interrupted in the region of these plates and a filling piece 6<SP>11</SP> which can easily be removed upward is inserted in this position. The component 3 has projections 11, which rest on supporting shoulders 12 of the neighbouring components and which are arranged above the junctions 13 of the melt conduits 14, 15. The components 3 are forced against the components 4 by the compression screw 17 mounted in arm 18 of the heating plate 7. In the embodiment of the invention shown in cross-section in Fig. 2 and in plan in Fig. 3, the plate 7 is supplemented on its two sides 23 and 24 by arms 18 and 19 to form a U-section member connected to one another by pipes 27. In both embodiments of the apparatus of the invention the upper horizontally extending part 21 of the plate 7 is provided with ribs 22 to prevent large quantities of condensate film being formed in the underside of the plate 21. The apparatus shown in Fig. 3 is provided with an additional component 28 containing shut-off cock 29 and provided with melt duct communicating through a flexible pipe 30 with a source of melt whereby several components 4 may be supplied with melt.
