Title: Self-adjustable fluid-operated brake mechanism
IPC: B60T13/18
Filed: 1926-07-26
Abstract: 255,906. Fiat Soc. Anon. July 25, 1925, [Convention date]. Fluid-pressure; hand and foot actuation.- Fluid-pressure brake mechanism for vehicles comprises a centrifugal pump driven from the transmission system and arranged to force liquid into the brake cylinders, the pedal which actuates the central valve being adapted also to apply pressure directly to the brake piston. Since the fluid-pressure exerted varies with the square of the speed of the pump compensation is obtained for the variation of the co-efficient of friction of the brake lining which is approximately inversely proportional to the speed so that the braking effect remains substantially constant. The pump 8, the shaft 13 of which is geared to the wheel 15 of the change speed gear of the vehicle, delivers liquid by passage 9 to the brake cylinder 10 from which normally it returns through the cock 6 connected by link 2 to the pedal 1. By depressing the pedal, the cock is moved towards the closed position and pressure is established in the brake cylinder, the piston 11 of which is connected by the lever 3 and rod 4 to the brakes. Continued movement of the pedal effects the engagement of a nut 2<1> on the link 2 with the lever 3 so that pressure directly applied by the operator is added to the fluid pressure.

Abstract: 1,012,373. Mining conveyers. GEWERK SCHAFT EISENHUTTE WESTFALIA. May 5, 1964 [Jan. 29, 1964; Feb. 29, 1964], No 18655/64. Heading B8A. A guard member for increasing the capacity of a mining conveyer is provided with a projecting member which is capable of providing a standing surface for a miner. In Fig. 1, an L-section member 12 is attached to a guard member 11, and a horizontal portion 12a forms a walkway. Tubular pieces 13 permit a further walkway member to be mounted on the member 12 if greater height is required. When the conveyer is to be steeply inclined, adjustable steps 14 are provided. Alternatively, tubular members used as rungs may be removably or permanently secured to the L-section member 12, Figs. 2, 3 (not shown).  In Figs. 4, 6, a guard extension 21 has keyhole-type apertures 26 to receive bolts 25 provided on step units 23, 24. To compensate for inclination of the conveyer, one end of the step may be located in a lower hole 26. In Fig. 8, steps 23 are pivotable to lie against the guard member 21 when not in use. A bracket 29 is pivoted to the step. In Fig. 9 steps 30 are in the form of flaps pivoted on spindles 31. The steps may be secured in the horizontal position by means, not shown. For supporting a walkway between the conveyer and a longwall lining, a tube 34 receives a rod 33 attached to a bracket 32 on which the walkway rests.

Filed: 1972-04-21
Abstract: 1324668 Fuel injection valves PHYSICS INTERNATIONAL CO 21 April 1972 [21 April 1971] 18672/72 Heading F1B Hydraulic fuel valve assembly for controlling the amount of fuel supplied to an engine that includes a fuel line 14, comprises a fluidcontaining hydraulic cylinder 30, the piston 26 of which can be moved to pressurize the fluid therein, a two-part plunger having an upper part 17 which is acted on by the fluid-pressure in the cylinder 30 and a lower portion 19 carrying a valve member 18 which co-operates with a valve seat 20, a passageway 32 connects the supply line 14 to the valve seat and a further passageway 36 couples the supply line to the hydraulic cylinder to vary the pressure in the hydraulic cylinder in accordance with the fuel-pressure in the supply line. The upper part 17 of the plunger has faces 31 which are acted on by the fuel-pressure to produce a force which resists the downward movement of the plunger in a direction to open the valve. This downward movement is effected by moving the piston 26 downwardly e.g. by a Piezo-electric actuator 24, to increase the pressure in the cylinder 30, the fluid therein then acting on the upper end surface of the plunger 17. To equalize the initial pressures on the opposite end faces of the plunger 17, the passageway 36 allows fuel to flow into the cylinder 30, past a check-valve 38, if the pressure of fuel supplied to the valve assembly is suddenly increased. If the fuel-pressure drops rapidly, then the valve 18 may open momentarily due to the higher force acting on its upper end. Under normal working conditons, the distance by which the valve opens is determined by the engagement of the bottom surface 66 of a collar 58 on the stem with the uppermost surface of a shim 62. The plungers are guided by a housing 44 to which they are assembled together with a shim 62 of appropriate thickness before the housing is inserted in the body 40 of the valve assembly. In a modification the check-valve 38 is replaced by a bellows which is subject internally to the pressure of the fuel and expands or contracts in accordance therewith. This enables a fluid other than fuel to be used in the hydraulic cylinder. In a further modification the check-valve is replaced by a free piston which slides along a bore and is exposed at one end face to the fuel-pressure and at the other end face to the pressure in the hydraulic cylinder. The piston thus takes up a position in which equal forces act on its opposite ends.

Abstract: 128,326. Carper, J. B. Nov. 7, 1918. Mineral and tar oils, purifying; oils and spirits for burning.-In refining mineral and tar oils, the oil is distilled, and the distillate is agitated in the cold with (1) a small proportion, say 1 per cent, of a solution of sulphuric acid, preferably of 60‹ Be., (2) a larger proportion, say 4 per cent, of a solution of sulphuric acid, (3) a solution of caustic alkali, and (4) pure soft water or petrol, waterwhite benzol, or other light spirit; the oil is then subjected to fractional distillation. The agitation during the chemical and washing treatment is effected by means of cold compressed air, and the oil is allowed to settle after each agitation. The process is applied to spent oils from the washing of coal-gas for the recovery of benzol and toluol, or to sharp, middle, creosote, naphtha, paraffin, cracked, and other oils. In one form of the process, the oil is first distilled up to 300 or 325‹ C., and, after the chemical treatment, distillates collecting up to 180‹ C., at 180-225‹ C., and at 225-360‹ C. are obtained. The light distillate is mixed with, say, 25 per cent of benzol, petrol, or other light oil, and the mixture is distilled up to 175-180‹ C. to produce a motor fuel; the produce may be redistilled up to 135-145‹ C. The middle distillate may be redistilled or not and used as a Diesel-engine fuel. The heavy distillate may be used as a paint for protecting against the action of the weather. In a modification, the original oil is fractionally distilled, and the distillates collecting up to 195‹ C., at 195-210‹ C., and at 210-240‹ are mixed, and the mixture is subjected to the chemical treatment. In the subsequent fractional distillation, a motor spirit is collected up to 130‹ C., then light and heavy rubber solvents, and finally a heavy oil for use as a lubricant or fuel. The apparatus consists of a tank A in which the distilled oil is agitated with reagents by means of cold compressed air admitted by a pipe B, together with a distilling-apparatus comprising a still C, condenser D, collectors E, E<1>, E<2>, and storage or settling-tanks F, G, G<1>.

Abstract: 636,315. Fluid-actuated valves. PRECISION DEVELOPMENTS CO., Ltd., BOX, F. J., and OLAH, G. July 24, 1945, No. 18893. [Class 135] In a piston slide valve displaceable within a ported cylindrical seat member against the action of resilient means by a fluid-pressure operated coaxial actuating unit, the actuating unit comprises a cylinder and a co-operating ram of smaller diameter than that of the valve seat member, and a passage is formed in the piston valve establishing communication between the cylinder and a pressure chamber, such as the valve inlet chamber in the case of a relief valve, or the valve outlet chamber in the case of a reducing valve. A relief valve comprises a housing 23, Fig. 1, for a cylindrical seat member 2 having radial ports 8 commimicating with an inlet chamber 9, radial ports 5, connected by passages 34 with an outlet chamber 6, and controlling edges 12 leading to the ports 8, and the ports 5. Within the seat member 2 is a piston valve 1 urged towards closure by springs 15 symmetrically arranged between ball-supported plates 16, 18 disposed between the valve and an adjusting screw 20. The valve 1 is formed with grooves 10, 11, and controlling edges 13 leading thereto which coact with the controlling edges 12, and with a bore 24 for the ram 25 of the actuating unit, said ram being freely supported by the casing cover 26. A space 27 above the ram 25 cornmunicates through a duct 30 and a recess 29 in the ram and radial passages 28 in the valve with the inlet chamber 9, whilst ducts 43, 44 connect the upper and lower surfaces respectively of the valve with the outlet chamber 6. In operation, on the pressure in the inlet chamber 9 exceeding a value predetermined by the springs 15, the valve 1 is forced upwards to separate the controlling edges 12, 13 and hence permit the flow of pressure fluid from the inlet chamber 9 through the ports 8 and symmetrically through the ports 5 to the outlet chamber 6. In a modification, the ram of the actuating unit is formed by an extension 35, Fig. 3, of the valve 1 which coacts with a cylinder 37 freely supported on the cover 26 and open to communication with the inlet chamber through passages 28, 36. When used as a reducing valve, the springs are arranged to bias the valve towards its open position and the space 27 communicates with the outlet chamber 6.
