Patent GB-118101-A (GB)
Title: Improvements in or relating to Feeding Devices for Pulverulent Fuel.
IPC: F23K3/00
Filed: 1918-07-17
Abstract: 118,101. Motala Verkstads Nya, Aktiebolag. Dec. 31. 1914, [Convention date]. Fuel, feeding.-In an air-current feeding- apparatus for pulverulent fuel, air blasts are delivered into the fuel container at various levels to stir and agitate the powder. In one form of the invention, Fig. 1, in connexion with a locomotive, the fuel is contained in a downwardly-tapering receptacle 2 on the tender, and is forced through a belt-mouthed conduit 1 leading to the furnace by an air blast delivered through a nozzle 68. The blasts for stirring the powder are supplied through ring pipes 90, 91. 92 surrounding the nozzle 68, and through conduits 75, 78 on the walls of the receptacle. The openings in the conduits deliver downwardly along the walls of the receptacle, and may be covered by plates to prevent choking. The whole of the air supply is controlled by a single valve 67, the ports in which are so arranged that the blasts through the conduits 75 and 78, the nozzle 68, and the rings 90, 91 and 92 are brought into operation in succession. In a modification, the nozzle and the rings are supplied from an air box beneath. The innermost ring branches from the nozzle 68, and the other two communicate directly with the box, the supplies to them being controlled by differently loaded valves, so that the three rings come into operation in succession. A more energetic stirring of the fuel can be effected by closing a valve 83 in the feed pipe 1, opening a spring-loaded valve 80 in the top of the fuel container, and turning on the blast. The valve 80 and a damper 84 in the feed pipe may be interconnected so that when one is open the other is closed An opening 79 in the feed pipe 1 normally allows air under pressure to escape from the space above the fuel in the receptacle 2. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter : In a modification, the nozzle 68 has a conical perforated top, and can be moved to or from the inlet to the feed pipe 1. The side walls of the fuel receptacle are vertical, and the front and rear walls are inclined to form a hoppershaped container. In this case, the whole of the contents for the supply of the stirring-blast are in the walls of the receptacle. In another modification, Fig. 10 (cancelled), acting under suction draught, the hopper-shaped receptacles are formed by inclining the side walls, and by an internal ridge 40. This subject-matter does not appear in the Specification as accepted.

Abstract: The lead salt of a compound of campherol and glucuronic acid excreted in the urine of organisms to which camphor has been given internally is precipitated by the addition of a lead salt and ammonia to the urine.  In an example the urine of a dog fed with camphor is treated with lead acetate and then with lead subacetate and ammonia.ALSO:p-Oxycamphor is manufactured from the compound of campherol and glucuronic acid excreted in the urine of organisms to which camphor has been given internally, by precipitating the lead salt of the said compound by the addition of a lead salt and ammonia to the urine, and treating the precipitate with a dilute acid.  The product is suitable for conversion into p-oxocamphor.  In an example, the urine of a dog fed with camphor is treated with lead acetate and then with lead subacetate and ammonia and the precipitated lead salt is treated with dilute sulphuric acid, first in the cold to remove excess lead as lead sulphate and then with heating on the water bath to produce p-oxycamphor, which is extracted with ether and recrystallized from ligroin.  Reference is also made to the production of the barium salt of the campherol-glucuronic acid compound.

Abstract: 417,138. Lubricating-pumps. TECALEMIT, Ltd., and CHALMERS, R. A., Great West Road, Brentford, Middlesex. May 1, 1933, No. 12658. [Class 102 (i).] In a multi-cylinder lubricating-pump the discharge from one of the pump cylinders is utilized for operating an auxiliary pump 13, which supplies the suction chamber of the main pump. The pump 13 comprises a motor cylinder 14 and a pump cylinder 15. The cylinder 14 is supplied with lubricant by a pipe 4, with check valve 45, under the control of a distributing valve 27. The pump cylinder draws through a filter 25 and valve 23 and discharges through a pipe 9. The pump piston 17 and the motor piston 16 are connected by a rod 18, which carries a cross-head 20, operating the valve rod 28 through springs 33, 34 adjustable by nuts 29, 30. The valve 27 is formed with two grooves 39, 40, which are engaged by spring-pressed balls to hold the valve either in the admission, or the exhaust position. In the position shown lubricant passes from the pipe 4 through a groove 43 and passage 44 to the cylinder 14. When the valve is moved to the left the cylinder 14 exhausts through radial and axial passages 42, 41 in the valve, and the suction stroke of the pump is effected by a spring 21.
