Abstract: 126,251. Dempster, R. & J., and Ballingall, J. M. Dec. 16, 1918. Hydrogen.-In the manufacture of hydrogen by passing steam over heated iron, the iron oxide produced is reduced in two stages; firstly, by means of previously used water gas which has been dried and condensed, termed secondary gas, and secondly, by means of fresh water gas, termed primary gas, which may afterwards be reused as secondary gas. The second operation may be of longer duration than the first, and the primary gas used at the commencement of the second operation may be passed away without being utilized as secondary gas.

Abstract: 153,139. West, J., Wild, W., and West's Gas Improvement Co. Aug. 30, 1919. Retort furnaces.-Vertical retorts g for the distillation of carbonaceous material are heated by a series of independently controlled and self-contained combustion chambers which are supplied with producer gas from a common duct j through jets e, and means are provided whereby the incoming secondary air, obtained direct from the atmosphere, is heated and delivered to the combustion chambers in such a manner to produce a uniform combustion and temperature along the chambers. Fig. 3 is a sectional plan showing the air ducts b, f, which are controlled by valves c and are arranged in the setting on each side of the combustion chambers, the ducts b having outlets near the jets e and the ducts f having outlets midway along the combustion chamber and inlets preferably at the ends near the gas jets so as to some extent to transfer heat from that end of the combustion chamber.

Filed: 1972-05-08
Abstract: 1434725 Valves I V PRESSURE CONTROLLERSLtd 17 July 1973 [8 May 1972] 21439/72 Heading F2V A control lever 9 is moved angularly in a first plane to rotate a valve means 1, 2, 3 and angularly in one or more planes perpendicular to the first to reciprocate a second valve means 6, 7, 8, the operation of one valve means controlling the fluid supply to the other. In the preferred embodiment, three reciprocal valves X, Y, Z are provided for actuation by the lever 9 which is biased by a spring 26 to a neutral position and provided with a cam 24 with two lobes E, F to open the valve 2 for movement of the lever either in direction CL or DL so that a chamber N in the rotary valve is connected to a pressure source 11. Further cams open the valves X and Y for movements in the directions DL and CL, respectively, to connect a chamber P with the pressure source or with a return line in accordance with the direction of movement. Angular movement of the lever 9 in direction AR or BR causes alignment of resilient plastics seals 2, 3 over conduits leading to ports 4, 5, the valve being correctly located by a mechanical detent (not shown). Further rotation of the valve aligns the seals with other conduits. A gate 17 and the frictional forces between the seals 2, 3 and a surface 14 ensures that the valve means 1, 2, 3 cannot be turned while the valve 2 is open. The cam 24 may have a spherical surface to co-operate with a plastics seal' 27. The part 16 may be directly mounted for rotation on the main body 10 of the valve, the part 12 being omitted. The spring 26 may be replaced by a pair of coaxial plungers mounted in the cam 24 and urged apart by a central spring.

Title: Improvements in or relating to separators for removing liquid particles from air
IPC: B01D46/24
Filed: 1960-06-18
Abstract: 988,692. Separating liquid particles from air. LOCKER INDUSTRIES Ltd. June 13, 1961 [June 18, 1960], No. 21496/60. Heading BIT. A separator for removing liquid particles from air comprises a first zone of matted non- absorbent fibrous material, such as glass fibre, and spaced from it a second zone consisting of layers of gauze-like mesh of non-absorbent material, such as wire mesh. Air laden with finely divided particles of liquid, e.g. oil, enters a container 10 through an inlet 11 and passes radially through the two zones 16 and 15 into a central tube 14 and leaves the separator by an outlet 13. The first zone consists of a mat of glass fibre mounted on and secured to a perforate cylinder 16a by binding strips 16b and enclosed by a further cylinder 16c of woven wire. The second zone, mounted coaxially with and inside the first and second therefrom consists of an inner cylinder of crimped phosphorbronze wire mesh an intermediate cylinder of non-crimped galvanized steel wire mesh, and an outer cylinder of crimped galvanized steel wire mesh, all mounted around the inner tube 14. Coalescence of the liquid particles and separation from the air stream is brought about in the first and second zones respectively. The liquid falls to a collecting chamber below the disc 4a and is discharged via the outlet hole 21 and the central tube 20. The tube 20 also serves to hold the unit together between the end flanges 12 and 19. In a modification, Figs. 2 and 3 (not shown), in which the unit is intended to be mounted with its axis horizontal, the second zone consists of flat circular discs of knitted and woven wire, and lies at one end of the container so that the air passes radially through the first zone and axially through the second. Liquid is discharged through a hole in the end mounting flange. A cylindrical shroud prevents direct impingement of the oil-laden air on the first zone of the separator.

Abstract: 1453999 Flexible hose; flanged joint EDDELBUTTEL & SCHNEIDER 15 May 1974 [22 May 1973] 21549/74 Heading F2G A rubber flange 3 constructed integrally with a rubber hose 1, reinforced by the layers of armouring, e.g. textile fabric or woven metal, of the hose and provided with through-holes 9 has thin annular laminae 4, preferably of metal, embedded in it to which armouring layers 2 are attached. One side of each layer 2 is secured, e.g. by gluing, vulcanizing or welding to laminae 4 so that there are two layers of armouring between each pair of laminae, the assembly of laminae and armouring layers being embedded in rubber. Lamina 6 adjacent to surface 5 of flange 3 acts as a support plate and has a projection 7 which reinforces the internal edge of the flange. When flange 3 is connected to the flange of an adjacent pipe by bolts located in holes 9 the compressive forces generated by the bolts are evenly distributed by means of a rear, metal, backing flange 10 vulcanized to flange 3 and act on lamina 6 so that the inner part of flange 3 is prevented from lifting away from the adjacent flange. Leakage between adjacent flanges is prevented by continuous annular rings 8 on face 5 of flange 3. Laminae 4 and 6 may each be split or may each consist of a number of elements to facilitate their incorporation into the flange.
