Filed: 1937-12-20
Abstract: 507,845. Powdered -- fuel engines. LEFNAER, O. Dec. 20, 1937, No. 35238. Convention date, Dec. 31, 1936. [Class 7 (ii)] An ante-chamber 4 has a valve 6 which can shut it off from the combustion space 3 of the engine, and while the chamber is shut off powdered fuel is vaporized in it. The valve 6 is open during part of the compression stroke so that air raised to the temperature of ignition of the powdered fuel is contained therein, and the valve is then closed and powdered fuel admitted at 5. Part of the powdered fuel burns until all oxygen in the chamber is used, and the heat produced vaporizes the remainder of the fuel. The valve 6 is opened again just before or at the end of the compression stroke, and the vaporized fuel issues into the combustion space and burns. There may be two or more antechambers for each cylinder, and vaporization may continue during one or more complete engine cycles. The fuel in passing from the ante-chamber to the combustion space may be whirled in a chamber 8 with spirally-arranged baffles so as to extract ash. The ash may be removed from the whirling chamber at the end of each stroke by the discharge of the exhaust gases through the exhaust valve 12. The inlet to the antechamber may be tangential so that whirling takes place in this chamber. The engine shown works on the four-stroke cycle, and the air-inlet valve is shown at 2. The invention is applicable to two-stroke engines.

Abstract: A high alumina refractory of increased strength, abrasion resistance and lower porosity contains 50 to 90% by weight Al2O3, 1-10% volatilized silica of particle size less than 50 microns more than half being finer than 10 microns, 0 to 10% Potter's Flint, the remainder if any being natural constituents of the ores used to provide the Al2O3 content.  The Al2O3 may be derived from calcined or tabular alumina, calcined Burley Diaspore, calcined Alabama bauxite, calcined South American bauxite, ball clay, fused alumina, fused mullite and fused bauxite, proportioned to give the desired Al2O3 content in the refractory produced. Examples are given containing 50%, 72%, 85% and 90% Al2O3.  The volatilized silica may be derived by depositing silica in the vapour phase e.g. in the reduction of silica to form silicon alloys, or reducing quartz with carbon treating the resulting vapour with an oxygen yielding gas and condensing the silica.  The high alumina materials are ground, screened and blended, 1-10% volatilized silica is added to the batch, a temporary binder (e.g. sulphite liquor) is added, the batch tempered with water, pressed into the desired shape, dried and fired. In certain examples Potter's Flint is used to adjust the Al2O3 content.

Title: Track-mounted telescopic hydraulic devices for controlling the speed of railway vehicles
Inventor: CHECKLEY PETER EDWARD
IPC: B61K7/00
Filed: 1965-08-23
Abstract: 1,115,724. Track brakes. DOWTY MINING EQUIPMENT Ltd. 17 Aug., 1966 [23 Aug., 1965], No. 36080/65. Heading F2E. In a track brake device of the kind in which telescopic piston and cylinder devices 15, 11 are mounted adjacent a rail to retard a railway vehicle by the action of each device against the periphery of a vehicle wheel, the piston member 15 is provided with a head 16 which is engageable by the flange of the vehicle wheel and which is laterally extended towards the rail head 19, whereby it passes close to the rail head during contraction and extension of the device, the position of the cylinder member 11 and the piston member 15 with respect to the rail being such that the line of rolling contact of the wheel flange with the head of the piston member is substantially offset from the longitudinal central axis of the device towards the head of the rail, as shown in Fig. 1, whereby the shock load due to the impact of the wheel flange on the head of the piston member is reduced by elastic deformation of the device. As shown in Fig. 2, the line of rolling contact passes through, or near to, a position shown by the arrow A which lies wholly to one side in the cylinder member 11 and the piston 15. The point 26 (Fig. 1) at which the wheel flange first engages the head 16 is spaced from the central axis of the device both in a direction transverse to the rail and in the longitudinal direction of the rail. Both the spacings produce an increased moment arm about the initial impact force F on the wheel flange to apply a bending moment to the piston member 15. The impact shock of the wheel flange on the head 16 is partially absorbed by elastic deformation of the telescopic device. The construction of the mounting bracket 12 with its bolt fastenings 14 may possess inherent resilience which contributes to the reduction of the inpact shock. The bracket 12 carries a pair of stops 24 which are engageable by lugs 25 on respective ears 22, 22<SP>1</SP> to permit a limit to the extension of the telescopic device. The ear 22 may be formed as a leaf spring or a pile of two or more leaf springs rigidly secured to the head 16. The bracket member 12 is provided with an adjustable mounting to the central web 27 of the rail 13 and this takes the form of a bolt 14 having a shank portion 34 which is eccentric with respect to the shank portion 31 and fits into a bore 35 in the rail web 27.
