Title: Improvements in feeding-devices for use with mine conveyers and for similar purposes
IPC: E21F13/06
Filed: 1933-04-07
Abstract: 421,114. Endless - chain conveyers. MINING ENGINEERING CO., Ltd., Meco Works, Worcester, and MOORE, M. S., Ivanhoe, Worcester Road, Malvern, Worcestershire. April 7, 1933, No. 10424. [Class 78 (i)] In mining-machines of the type comprising a rotary loader bar co-operating with a comb, &c., over which the broken coal, &c., is tossed on to a conveyer for removal, the side of the comb 5 adjacent the bar 9 is provided with downward-tapering ribs 27 which project toward the bar between the picks 25 and encircle it for a substantial portion of its circumference both above and below the axis of the bar. The ribs 27 terminate a short distance above the bottom of the channel cut out by the picks of the loader bar and may be integral with the comb 5 or be on a separate casting which can be bolted to the comb on either side. Tapered teeth 29, preferably removable, are fitted in holes in the comb to extend tangentially to the bar 9 between the staggered picks 25. The bar 9 and comb 5 may be made in a plurality of sections, and for breaking away incompletely loosened coal at the back of the cut the bar end section may be provided with picks more closely spaced than those on the rest of the bar 9, and the comb and section may have its ribs 27 on a lining of bronze which forms a side abutment for the free end of the bar, and may have tapered teeth aligned with alternate picks to enter the grooves made by the picks and break away their sides. One of the shafts 6 carrying the conveyer 8 drives the bar 9 through gearing which has pinions sufficiently small to allow the top of the gear-box 4 to slope down alongside the inclined part of the conveyer, the pinion on the bar 9 being slidable to disconnect the bar. The machine is pivoted at 2 to a base 1.

Patent GB-215015-A (GB)
Title: Improvements in gas indicating devices
IPC: G01N7/10
Filed: 1924-04-28
Abstract: 215,015. NeUissen, W. April 28, 1923, [Convention date]. Diffusion apparatus for gases.-In apparatus for indicating the presence of foraign gases in air by means of a diffusion cell and having, as described in Specification 208,718, a chamber containing sufficient air to effect several rinsings of the apparatus, conduits are provided between the air-chamber and the interior of the cell and and between the interior of the cell and the vessel within which the cell is enclosed, so that the rinsing air flows first through the interior of the cell and then through the enclosing vessel. The conduits may be controlled by a single member, which may also conrol the connection between the diffusion cell and the pressure gauge, the arrangement being such that the pressure gauge is put into communication with the atmosphere to restore it to zero after an indication has been obtained, and is cut off from the remainder of the apparatus during rinsing. As shown in Fig. 1, the apparatus comprises a chamber 1, containing compressed air for rinsing, and a diffusion cell 4 enclosed within a vessel 3 into which is fitted a valve 6 rotatable by means of a handle 7. The valve 6, as shown in Fig. 3, has three ports 8 - - 10, the angle between the first and the third being 120 and that between the last two 90. These ports are adapted to register with channels 11 - - 13 in the neck of the vessel 3, these channels being so arranged that the angle between the first and the third is 120 and that between the second and the third 90. Channel 11 is connected by a conduit 14 to the pressure gauge 15, channel 12 by a conduit 17 with the chamber 1, and channel 13 by a conduit 18 with the vessel 3. In operation, the valve 6 is turned to the position shown in Fig. 3, in which position the cell communicates by way of,port 9, channel 11, and conduit 14 with the pressure gauge. The gas to be tested is introduced into the vessel 3 through a pipe 19, this pipe fitting loosely into the vessel so as to prevent any excessive increase of pressure therein. When an indication has been obtained, the valve is turned so that port 8 registers with channel 11, in which position the pressure gauge is brought into contact with the atmosphere by way of the cell, port 10, and channel 13. To rinse the appartus, the valve is turned so that port 9 registers with the channel 13 and port 10 with channel 12. Air from the vessel 1 then passes by way of conduit 17 and channel 12 into the cell and thence through port 9 and channel 13 into the vessel 3. A new indication can then be obtained by turning the valve 6 to its original position and introducing a further quantity of gas.

Title: Improvements in or relating to altitude control means for internal combustion engines
IPC: F02D1/00
Filed: 1931-04-09
Abstract: 376,341. Regulating ; spray carburetters. PENN, R. J., Royal Aircraft Establishment, South Farnborough, Hampshire. April 9, 1931, No. 10481. [Classes 7 (iii) and 7 (vi).] In engines having an altitude control acting through a servomotor to vary the proportion of fuel to air with changes in atmospheric pressure, hand control of the actuating- fluid of the servomotor is provided for cutting out the altitude control, when desired. In the form shown barometric capsules 2 actuate a piston valve 9 which controls the admission and release of oil under pressure to and from opposite sides of a servomotor piston 5, the rod 17 of which is connected to the altitude control valve of the carburetter. The valve 9 connects passages 14, 15, leading to opposite sides of the servomotor piston, to the inlet 13 or outlet 16 of the oil pressure. Two manually-actuated three-way cocks 33, 34 are arranged in connection with these passages and with a byepass 160 as shown, and form the hand control. When the cocks are in the position shown in Fig. 1, the servomotor is in action, but with the cocks set as shown in Fig. 2, the servomotor and altitude control are cut out. A follow-up device is provided for the relay by connecting the rod 19 of the capsules to a lever 18 pivoted at 20 and connected to the rod 17. The initial setting of the altitude control valve may be adjusted by altering the position of the lever connected thereto. The rate of opening of the cock is varied by adjusting the pivot 20 along a slot 30 by means of a bell crank 28 and screw 31. The rod 19 also engages the slot 30, and the rate of opening of the cock may be predetermined by the shaping of the slot 30. The altitude control valve may regulate the air intake to the carburetter, or it may regulate the fuel by varying either the passage at the jet or the pressure in the float chamber.

Abstract: 129,083. Jenkins, H. C., and C. I. (1914) Syndicate. June 28, 1918. Levels, regulating.-Discharge of liquid from an electrolytic cell is automatically effected by a rise in level of liquid in a feed tank which has a restricted outlet into the cell. As shown, the feed tank B<2>, supplied from a pipe B and connected to the cell proper by a passage opposing frictional resistance to flow, freely communicates with a well D containing a float D<1>. The adjustable stem D<5> of the float passes through a rubber diaphragm and pipe D<4> and operates a valve D<2> in a discharge passage C<3>, D<3> leading from a tank C<2>. This tank is connected to the cell by a pipe c and contains a weir over which the discharge of liquid takes place when the valve is not in action. Frictional resistance to flow may be attained by diminishing the diameters of the outlet D<3> and the pipes leading from the feed tank to the cell, or by inserting stoppers with holes of various sizes.
