Title: Improved method of recovering coal from waste
IPC: B03D1/06
Filed: 1922-05-12
Abstract: 206,869. Thornley, F. C. May 12, 1922. Grant of Patent refused. Flotation processes.-A process for separating coal from gangue consists in mixing the coalbearing material with a liquid such as water, and a substance such as cresol, paraffin oil, or wood tar, and violently agitating the mixture in a closed chamber at a pressure less than atmospheric. The pulp of coal and water is fed into this chamber, from a sufficient height, through an inlet the area of which is at most one-fourth that of the outlet. This causes a partial vacuum to be set up which expands the gas adhering to the particles. The bared particles become coated with oil and mix with the air or gas which is supplied through suitable openings provided with automatic control valves. The froth formed is then discharged into a liquid contained in a settling-tank in which the mixture comes to rest under atmospheric pressure. The coal-bearing froth is discharged over an overflow whilst the gangue settles to the bottom.

Title: Improvements in and relating to a manoeuvring device for propeller shafts
IPC: B63H3/08
Filed: 1948-05-19
Abstract: 657,110. Variable-pitch propellers. KROLDRUP, A. May 19, 1948, No. 13608. Convention date, June 23, 1947. [Class 114] [Also in Group XXIX] In a control device for propeller shafts having propellers which for the purpose of reversing or adjusting the setting of the blades are adjustable by means of a hydraulically actuated adjustment member, e.g. a piston, the cylinder of which is in communication with a constantly operating liquid pump, the pump is provided with a spring influenced byepass valve through which the liquid under pressure supplied by the pump can escape, preferably for being returned to the suction chamber of the pump, when not being used for reversing or adjusting the propeller blades. The invention is shown applied to the device described in Specification 609,529. When a reversing or blade setting operation is not being performed the pump 11 draws oil through a suction pipe 11b from the bottom of a casing 17 and delivers it into a pressure chamber 11a, a channel 34, through a valve 38 into a pipe 47 to the underside of a spindle 45 which it raises to lift the valve 41 against the action of its spring 48, thereby allowing oil delivered by the pump to flow into a pipe 44 which leads through a cooler and a filter (not shown), back to the bottom of casing 17. To change the blade setting, the hand-wheel 18 of the valve 38 is turned to cut off oil pressure in the pipe 47, the valve 41 closes by the action of its spring 48, and the pump pressure rises sufficiently to effect the change in setting of the propeller blades by the oil-flow from the channel 34 to the above-mentioned cylinder. When the propeller blades have taken up their new position, the valve 38 opens automatically to admit oil under pressure to the pipe 47 to raise the spindle 45 and open the valve 41 of the byepass pipe 44.

Abstract: 356,763. Gas condensing processes. CLAPHAM, T. A., Wellington Foundry, Keighley, Yorkshire. May 3, 1930, No. 13628. [Class 55 (ii).] Naphthalene and moisture are removed from coal gas by passing the gas through a series of heat-exchanging chambers firstly being cooled by indirect contact with gas that has already passed through the chambers and secondly cooling by indirect contact with cold liquid, the gas being brought into contact with a solvent oil throughout the treatment. The gas enters the primary chamber 2 through an inlet at the top of the chamber and passes over a series of tubes 3 comprising a number of sections a .. d. The gas issues by a pipe 7 and flows over a series of tubes 6, containing cooling liquid, upwards and downwards consecutively in similar chambers 4, 5. The cold gases return through pipe 9 to the primary chamber by passing through the tubes 3 in a zig-zag manner from one section to the next to outlet 10, this chamber acting as a precooler for the inflowing gases. Tubes 6 are arranged so that the cooling fluid flows horizontally in a zig-zag manner in one row of tubes before rising to the next higher row. Naphthalene collecting upon the tubes is removed by spraying solvent oil which is delivered through nozzles 11, 11a, 11b into the upper parts of the chambers.

Filed: 1925-05-26
Abstract: 250,521. Budd Wheel Co., (Assignees of Nelson, E. A.). April 9, 1925, [Convention date]. Rolling discs.-A machine for rolling tapered wheel discs comprises radially traversing blank working rolls and a rotating blank support which is automatically moved up to and away from the rolls which are driven by contact with the work. The blank holder B is carried rotatably in a cradle 28 mounted in a sub-base 10, and is rotated by a motor 12 through bevel gears 16 driving a vertical shaft 18. The hub 43 is bored out to receive the splined sleeve 48 keyed to the driving shaft 18. A bearing 42 and the hub 43 are clamped on the sleeve between a shoulder,49 and a screwed ring 50. Axial movement is effected by toggles G, carrying dogs 19 and 20 engaging with dogs 21 on frames 22 carrying the rolls R<1>, R<2> and sliding in undercut guides in the head H. The toggles comprise linked arms 23 and 24 the latter being connected to the cradle structure 28, Figs. 1<a> and 1<b>. The toggle arm 23 has a bent integral extension with an upper end 35 carrying an adjustable dog 19 engaged, by a dog 21 on the inward and idle traverse of the rolls. The toggles are gradually raised to the position in which the extreme of approach of the blank support B to the rolls R', R<2> is established, and are locked in this position by moving the centre bearing of the toggles slightly past the vertical centre line just as the rolls nearly meet in the centre. At the end of the working stroke, the dog 21 engages the dog 20 to unlock the toggles and the blank support drops rapidly away from the rolls R'. The mechanism for carrying and traversing the rolls R<1>, R<2> is supported adjustably between limiting stop nuts 83 on four columns C, Fig. 1<a> connected at the top by beams 79. Safety springs 82 take the upward pressure of the roll carrying head H during rolling. An automatically reversing motor 89 for traversing the frames 22 is mounted on the top of the head, and drives through gears 115 and a screw 104 working in a tapped hub 117. The mechanism is enclosed in an oil tight casing 109 for lubricant. An oil pump 63 forces oil up through the centre of a chamber 61 to bearings and guideways &c., and up the hollow shaft 18 to underside of blank support and, pouring down to lubricate the gears, returns to the side of the chamber 61 which may be large enough to act as a sump. The blanks are fed into and removed from the machine by the mechanism described in Specification 249,368.
