Title: Improvements relating to Furnace Retorts.
Inventor: SMITH CHARLES HOWARD
IPC: C10B7/02
Filed: 1919-02-17
Abstract: 123,739. Smith, C. H. Feb. 18, 1918, [Convention date]. Retori furnaces; charging and discharging; casings and walls.-In a combined furnace and retort for the treatment of coal, the retort is formed at its lower part with an in. ternal longitudinal rib, and the charge is mixed and conveyed by blades on two parallel rotating shafts, so spaced that their blades overlap. The retort is of inverted heart-shaped section as shown in Fig. 4, and is built up of hollow tiles 4, 5, 6, arranged to form flues 4<a>, 5<a>, 6<a>, running the length of the retort. Burner nozzles 39 project into the open ends of the flues, and the products of combustion are withdrawn through a downcast flue 44, the combustion flues being connected at this end of the furnace by openings in the partition walls. The tiles 4, 5, 6 are preferably made of carborundum, or a mixture containing this material. Surrounding the combustion flues is a layer of fire-brick 12 which serves to store heat, and around this is a heat-insulating layer 13 of a diatomaceous earth brick known as " sigur " brick. The whole is enclosed within a metal casing made in two parts meeting in an horizontal plane about midway of the height of the structure, and between this casing and the brickwork in the upper part a layer 21 of asbestos is interposed to allow for expansion. The end walls are similarly lined with brick. The shafts 7, 8 are supported in open ended annular bearings 24, 25, of which the latter are mounted in removable covers sufficiently large to allow the removal of the shafts from the retort. The linings for the bearings are made of an alloy of copper, aluminium, and iron commercially known as " Ampco " metal. The shafts are hollow and may be made in a number of sections connected by spigot and socket joints. and locked together by the shafts of the blades. These latter are inclined to their plane of rotation at an angle which may vary from 35 degrees at the charging end to 45 degrees at the discharging end of the retort. Each blade g<a>, Fig. 12, is cast on its shaft 9<b>, which fits into a socket in the rotating shaft, and is secured in position by a nut, The material is fed into the retort by a screw conveyer, and after treatment passes down a divided shoot 57 to a rotary discharging drum 58. The material is broken up and forced into the pockets of the drum by rotary arms 64. Gaseous products are led off from the retort through pipes 46, 47 and passed to an hydraulic main 50, which is supported on rollers to allow of free expansion. Clearing devices are provided in connexion with the elbows 51, 52, 53. Specifications 101,539, [Class 55 (i), Coking &c.J, 106,084. and 111,285, [Class 55 (i). Coking &c.] , are referred to.

Filed: 1960-02-03
Abstract: 943,742. Moulding concrete tubes. OTTOVERKEN A.B. Feb. 3, 1960, No. 3933/60. Heading B5A. In an apparatus for simultaneously casting and vibrating a number of concrete tubes in moulds contained in a single block, an apertured carrier plate 10, Fig. 2, after being moved laterally to a point between a vertically movable mould block 6 and a bridge 5 supporting cores 4, is then raised to form the base on which the tubes are cast. The cores 4, after having been vibrated are withdrawn through the holes in the carrier plate 10, and the mould block 6 raised so that the concrete tubes can be conveyed away from the apparatus on the plate 10. The mould block 6 movable on guides 6<SP>1</SP>, lowered to the casting position shown in Fig. 2, is charged by hoppers. The mix is then compressed by hydraulically actuated pistons 8 mounted on a bridge 7 and is lowered to the posit on shown in Fig. 2. After casting, the pistons, which are rotatable to prevent adherance to the concrete, are withdrawn together with the mould 6 and the cores 4. The carrier plate 10 on which the casting is supported is conveyed away after being lowered on to rails. The socket end of the tube 19, Fig. 4, is provided with a former 29 of resilient material which forms a protecting buffer round the carrier plate 10. The former 29 can be of metal providing a resilient connection is made between it and the carrier plate 10. A relative turning motion between the core 4 and the casting 19 is imparted by means of a tongue 30 fixed to the core 4 which engages a helical groove in the sleeve 32 which on the initial withdrawal of the core is prevented from moving by springs 33. Towards the end of the vibratory operation an end forming collar may be inserted between the casting and the ram 8, the end of which may be provided with a resilient insert. In a further embodiment the bushes 29 are supported on a carrier plate retained by thin columns which allow vibration to take place, the rams 8 exerting a compressive force to the mix which is vibrated as before. The displacement of the bridges 5, 7 and the block 6 may be effected by chain, toothed gearing or jacks and the ram 8 may be replaced by a spring. The carrier plates can be transported by fork lift truck.

Abstract: 1,208,351. Vacuum filling machine. WIPAC DEVELOPMENT Ltd. 24 Jan., 1969 [26 Jan., 1968], No. 4354/68. Headings B8C and B8T. A vacuum filling machine comprises a chamber 24 connected to a vacuum pump and an air admittance valve through an opening (29), Fig. 3 (not shown), and a connection through a hole 28 in the upper wall of the chamber to a fluid control valve 34. The chamber 24, in the form of a steel cylinder, is clamped at the upper end to the fixed table 13 and sealed by rubber disks, 27. The container to be filled is placed on a table 22 carried on a shaft 20. Manual switches operate a circuit to cause a table 14 to be driven up by air cylinders 15 to both raise the table 22 and seal the lower end of the chamber 24 by means of a ring 25a. When sealed, the chamber 24 containing the vessel to be filled is evacuated, through contact of a strip (44) on the platform 14 with a switch (45), Fig. 3 (not shown), operating a vacuum valve, (41). When a sufficient pressure in the chamber 24 is sensed by a device (43), the table 22 is raised by a further air cylinder 16 to seal the open upper side of the container against the rubber seal 27. A pressure switch (62) responds to pressure in the air cylinder 16 to shut off the vacuum and admit air into the chamber 24. The container remaining vacuum sealed begins to fill with the fluid in the chamber 30 when the valve 34 is opened. Just before filling is completed the container may be moved away from the seal 27, the operation being set by a time switch. The fluid valve 34 remains open and filling is completed after the container is separated from the rubber seal 27. The fluid valve is closed and the machine set in position for another cycle when the switch (45), is released by the strip (44) on descent of the table 14. The machine may fill resin into a container enclosing a magneto coil, where the resin solidifies to form an insulating agent.

Filed: 1941-04-01
Abstract: 548,353. Coating with metals, gilding, silvering; reflectors; electric lamps; discharge lamps. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., ALDINGTON, J. N., and MEADOWCROFT, A. J. April 1, 1941, No. 4378. [Class 82 (ii)] [Also in Groups XI, XX and XL] In the production of a reflecting surface on part of the interior wall of a glass vessel, e.g. an electric lamp or electric discharge lamp, reflecting metal is deposited on the.interior of the vessel and 'the metal is dissolved away from the deposit over the area from which it is to be removed by supporting the vessel with the part where the deposited metal is to remain uppermost and introducing a liquid solvent into the vessel until the level of the solvent covers the area of metal to be removed. The metal deposited may be aluminium and the solvent a dilute solution of caustic soda. The metallic deposit may be formed by evaporating the metal within the glass vessel and the evaporation is carried out at a place more closely adjacent to the area where the surface is to remain than the area from which it is subsequently removed. A clear space may be provided within the reflecting area by means of a ferrous metal plate held over that space by magnetic attraction exerted from outside the vessel. The interior of the vessel may be cleaned by washing it out with a dilute acid such as hydrochloric or nitric acids, rinsing with acetone and then heating to a temperature sufficient to dry the bulb and drive off occluded gases in the interior of the latter. The metal may be evaporated by enclosing it within a heater coil, e.g. a tungsten helix, supported between two electrodes, the whole being pressed into the bulb which is then sealed and connected to an exhaust pump; the heater then being raised to 1800‹C. by the passage of current. Coatings of copper, silver, magnesium and gold are also referred to.
