Title: Improvements in automatic regulators
IPC: G05D23/12
Filed: 1929-08-27
Abstract: 338,907. Wingfield, B. T. Aug. 27, 1929. Valves controlled by pilot or relay valves.-An automatic pressure, temperature, or volume regulator comprises a device 8, responsive to pressure (as shown in the example), temperature, or volume, the movements of an operating arm 11 of which are transmitted, without amplification, through a link 12 to a lever 21 controlling the opening and closing of a leak-off pilot valve 5, 6 and a readjusting arm 16 for adjusting the mean value of the regulated condition. The valve 5, 6 regulates the escape of compressed air from a capsule 4, thereby supplying compressed air from a connection 1 through a valve 2 and connection 7 to a device, such as a fluid-actuated main valve, causing the regulation of the desired quantity, or exhausting it therefrom. The device 8 may carry a pen arm 9 pivoted at 24 recording values of the regulated condition on a disc 10 rotated by clockwork. Pivoted at 19 on a bracket 17 is the mechanically operated readjusting arm 16 the end 23 of which follows the displacements of a cam 18 rotating with the disc 10, the contour of which cam corresponds to the time-pressure &c. conditions to be maintained. The intermediate lever 14 is pivoted at 15 on the readjusting arm 16, the length of which is equal to that of the pen arm 9, the fulcrums 19 and 24 of these arms being equidistant from the centre of the disc 10. With the arm 16 in any position, thus fixing the mean valve of the regulated condition, if the arm 9 is nearer the centre of the disc 10 than the arm 16, the pilot valve 5 is opened and operates the main valve or similar device to raise the pressure, or other condition, until the correct value is recorded bv the arm 9. Thus the curve traced out by the arm 9 corresponds to the contour of the cam 18, and angular displacements of the arm 16 produce equal angular displacements of the arm 9. A plurality of regulators may be adjusted to the same cycle as followed by the arm 16, and the bourdon tube 8 may be connected to a thermostatic bulb to regulate temperature or may be replaced by a float acting on the spindle 24 for regulation of volume. The arm 16 may be actuated manually or by a device responsive to a condition of another fluid. or it may be adjusted by a second regulator for the regulation of, say, volume in terms of pressure &c. The pilot valve 5 may be replaced by an electric switch controlling a main valve or similar device.

Keys 20 are welded in position and keys 21 are retained in position by bolts 16. The cooling water is supplied to one rim 12 by inlet pipe 30, formed axially in shaft 2, passage 34 in a manifold 8 and pipe 33, 36, 37, and escapes by a pipe adjacent this connection but separated by a dam so that the water must circulate completely round the rim. This outlet pipe 39 is connected to a passage 38 in the manifold 8 which is connected to a pipe 40 connected to the inlet pipe of the other brake rim round which water is similarly circulated and escapes finally by passages 41, 44 in the manifold 8 and outlet passage 42 formed axially in shaft 2. The rim 25 is corrugated to allow for expansion. The water connections to the two brake rims are arranged diametrically opposite and weights 46 are provided for balancing purposes. In a modification the rim 13 is bolted to the rim 11 and the edges of rims 12, 13 are made flush to obtain maximum width of braking face, the rims are formed with engaging faces preventing lateral movement. In further modifications the wear flanges 19 are made separate from the rim 12 and the flanges and rim are held in place by lugs 20, 21, or the rim is keyed to the flanges and the flanges are keyed to the drum.

Abstract: 688,422. Pebble-heating apparatus. PHILLIPS PETROLEUM CO. Nov. 1, 1950, No. 26666/50. Classes 64 (i) and 64 (ii) A pebble-heating chamber is provided with a moving bed of pebbles supported by a single selfsupporting refractory dome dividing the chamber into a heating zone above the dome and a combustion-gas zone below the dome, the pebble outlet from the chamber extending centrally through the dome and downwardly through the combustion zone. In the form shown in Fig. 1, the pebble-heating chamber comprises a shell 11 lined with common refractory material 14 such as fire brick with an inner lining 15 of super refractory material such as silicon carbide. The pebbles, formed of solid refractory material such as silicon carbide, alumina, periclase, beryllia, stellite, zinconia or mullite, are in the form of a fluent bed 28 moving between an inlet 29 and an outlet 23. The pebble bed is supported by a perforated dome 16 of super refractory material formed into tapered bricks 17, Fig. 2, arranged in ring formation. Grooves at the sides of the assembled bricks form holes for the passage of hot gases from a combustion chamber below the dome fitted with tangential gas burners 25. Methane-rich gas with oxygen may be used. To ensure the passage of hot gas upwardly through the centre of the pebble bed, a baffle 26 is provided. The lower part of the bed is formed of aggregate 27 or a refractory cone may replace the aggregate. The pebble outlet comprises an upper super refractory throat part 18 formed in sections and a lower part 23 formed of refractory rings 24 with an expansion joint between the parts. Fig. 5 shows the use of the heater 11 in conjunction with a lower pebble flow chamber 35 for heating gas which enters at 36 and leaves at 37, the pebbles being raised by elevator 38 from the outlet of chamber 35 to the inlet of chamber 11. To prevent the passage of combustion gases from one chamber to the other, hot inert gas may be forced into the pebble outlet conduit. Specification 688,421 is referred to.

An air heating stove is characterized in that the combustion chamber 24 and heat exchanger are contained in a first cube-shaped box 2, the source of heat 8 being fitted to the centre of one of the sides of the box, and that the air supply unit is contained in a similar box 1 of which any side can be attached to any side of box 2 such that the general direction of air flow through the heat exchanger will be substantially parallel with the side of box 2 on to which heat source 8 is fitted. As shown, air from blower 4 passes through delivery end 7 into box 2 containing burner 8 and flame tube 10 which forms part of combustion chamber 24. The air flows through channels 20, 21 and 23 between hot flues 14 to 18 and also round the outside of the flues against the internal walls at 29, 30, 31. The flue gases on leaving combustion chamber 24 are directed into flue 14 by the reverse flow header can 11 whose deflecting wall 12 is coned. The flame tube 10 has its top edge extending beyond edge 33 in order to ensure better gas distribution. The flues 14, 16 and 17 are closed by detachable panels 27 and 28. Panels 27 have attached to them removable deflector plates 32 which are tapered. Deflector plates 34 are provided in the air passages 20 overlying baffles 22 to deflect air on to the hottest parts of the combustion chamber. A modification, Figs. 21, 22 and 23 (not shown), incorporates a circulating box for effectively connecting one face of one box containing an opening with a face of the other box also containing an opening. Figs. 10 to 20 (not shown), indicate how the boxes 1, 2 may be positioned relative to one another.
