Title: Shell and Tube Heat Exchanger.
IPC: F28D7/06
Filed: 1966-11-16
Abstract: 1,167,168. Shell and tube heat exchangers. COMBUSTION ENG. Inc. 16 Nov., 1966 [27 Dec., 1965], No. 51394/66. Heading F4A. A spherical vapour generator 12 is supplied with feedwater through openings 40 in an annular inlet tube 38, the water passing upwardly over water heating tube bundles 26 located within an annular baffle 32 which divides the liquid space 16 of the generator into downcomer and generation sections 34, 36 respectively. Steam so generated passes through screen dryer elements 94 to vapour outlet 20, whilst separated water is recirculated through downcomer section 34. Heating fluid from inlet nozzle 52 passes through duct 64 and sleeve 66 to upper inlet compartment 58 in central manifold 30, and then through the U-tubes 28 to lower outlet compartment 60, to exit through outlet nozzle 54. The U-tubes which are formed in vertical rows, extend in a circular arc outwardly towards the baffle 32 (Fig. 2), and are carried by tube supports 74 extending between annular structural members 78, 80. The latter are in turn supported on radial ribs 82. Manholes 22 and 48 provide access to the shell 12 and the manifold 30 respectively. The sleeve 66 is threadedly secured at its upper end to an annular plate 56 defining the upper and lower manifold chambers 58, 60 respectively, and is in mating engagement through a flange 90 on its end with a like flange 92 on duct 64. The sleeve 66 and the flange 90 on its end are formed of material having a different thermal expansion from that of duct 64, so that on cooling down from operating temperature, the sleeve 66 if the top threaded connections were released, would telescope over the duct 64 thereby allowing access room to effect repairs within the manifold 30.

Title: Method for fabricating a pressure vessel wall
IPC: F16L9/04
Filed: 1971-07-16
Abstract: 1364892 Casting processes; welding by fusion LA SOUDURE ELECTRIQUE AUTOGENE PROCEDES ARCOS SA 16 July 1971 [24 Sept 1970] 51396/73 Divided out of 1364891 Headings B3F and B3R A method of making a wall for a pressure vessel comprises attaching a reinforcing sheet of metal 20 to a first layer 21 of metal and adding a second layer of metal to the surface of the reinforcing sheet by a welding process, the said second layer being added in a series of welding passes which are rectilinear and juxtaposed. In the embodiment shown in Fig. 2, a water-cooled copper bar 40 is placed against the surface of the metal plate 20 and a first bead 24 of metal deposited on the surface of the plate 20 by electroslag welding using a movable L-shaped mould 28, the arm of the mould over-lapping the bar 40. After completion of the first bead 24, further beads are deposited in a similar manner until a layer of metal of the required dimension has been built up. During the deposition of each bead the arm of the mould overlaps the previously deposited bead. Instead of using a starter bar 20, a channel shaped mould having a detachable side (41), Fig. 3 (not shown), maybe used. After the first bead has been deposited, the side 41 is removed to leave an L-shaped mould and the process continues as before. The length of each bead may be such that a layer of approximately circular shape is formed, copper bars (37) being placed at each end of each bead to prevent run-off of the molten metal, Fig. 4 (not shown). Instead of electroslag welding, submerged arc, plasma arc, metal arc inert gas or tungsten arc inert gas processes may be used to build-up the second metal layer. The bimetallic material forming the reinforcing sheet 20 and said first layer 21, may be roll-clad, explosion clad, vacuum brazed or otherwise mill clad.

Title: Improvements in or relating to reflectors for electromagnetic waves
IPC: H01Q15/14
Filed: 1965-12-07
Abstract: An electromagnetic wave reflector comprises a reflecting layer for such waves which is supported on at least one rigid block of an expanded cellular material having a density of from 0.5 to 0.8gm/cc. The said material is made by grinding together, in the presence of moisture, siliceous sand, cement, and aluminium powder and hardening it in an autoclave after expansion. Following any machining of the block, the working surface may be partially vitrified by a flame and a metallic coating be deposited by spraying or otherwise. Alternatively, a synthetic resin coating may be applied to the working face, which is left unvitrified, and be followed by a metallic coating, or a single coating of synthetic resin loaded with metallic particles may be used.  Any of the aforesaid coatings may be machined, for greater precision.  Blocks may be joined together with adhesive and any remaining exposed surfaces may be sealed against moisture penetration.  A part paraboloidal aerial is described, wherein the reflector assembly (5), Figs. 5, 6 (not shown) comprises four blocks (1a), (1b), (1c), (1d) and an arm (6) of the same cellular material, which is cemented to the assembly for carrying the feed horn (7).  In another arrangement, a paraboloidal reflector comprises a centre block (22) and a number of petal blocks (21), all made of the expanded cellular material, which are cemented together.

Abstract: 1,147,238. Rotary positive-displacement compressors. WORTHINGTON CORP. Nov.22, 1966 [Dec.10, 1965], No.52242/66. Heading F1F. Air-compressing apparatus includes a rotary positive-displacement compressor 12 having a control valve 16 on the low-pressure side thereof, and a pump 26 that by-passes a non-return valve 22 on the high-pressure side of the compressor and expels compressed air from the latter into either an air-receiver 18 or the atmosphere whenever the valve 16 closes to effect unloading of the compressor. Preferably, the valve 16 is coupled by a rod 40 to a valve 38, which controls the rate of flow of lubricating oil through a pipe 32 into the compressor, so as to reduce said rate when the compressor is unloaded and thereby minimize the work done by the pump 26. Oil mixed with the compressed air is collected in the receiver 18 and flows through filtering means 34 and cooling means 36 before it reaches the valve 38. A separator 30 removes oil and water from the compressed air as it leaves the receiver through a pipe 28. When the valve 16 closes, the pump 26 may reduce the pressure in the associated pipe 24 and the outlet side of the compressor to a negative value relative to atmospheric pressure; and the pump may be driven continuously by the compressor or, alternatively, only while the valve 16 is closed, in which case the pump may be coupled to the compressor by a clutch (not shown). The rod 40 may be replaced by a rod (46), Fig. 2 (not shown), which is operated by a diaphragm or piston (48) is response to pressure changes effected by an actuator (43) for the valve 16.

Abstract: 1419101 Crop harvester INTERNATIONAL HARVESTER CO 13 Nov 1972 [18 Nov 1971] 52333/72 Heading A1F A crop harvester has a lateral cutting bar 38, a rotating gathering cylinder 40 with either discs 237 Fig. 10 (not shown) helical flighting 48 and a collecting platform with a doublehanded auger 26 to reduce the width of the crop and direct it towards a conveyor 17 leading to a chopper head 14 and a discharge duct 35 into a trailing wagon. The cylinder is characterised by having a number of pairs of gathering fingers 62 around the periphery of the discs or flighting 48 which are camoperated with rotation of the cylinder 40 to move through about 90 from a working position where they lie along a line parallel to the axis of the cylinder 40 to a clearance position trailing along the periphery of the cylinder 40. The cylinder 40 and the auger 26 direct the crop both rearward and toward the line 3-3 and thus toward the conveyor 17, the chopper 14 and discharge duct 35. Attached to opposite sides of the flights 48 of the cylinder 40 at points near the periphery are pairs of finger units 58. At the forward lower quadrant of the cylinder, the fingers are extended as indicated but after passing the cutter bar 38, the fingers 62 rotate about an axis radial to the cylinder 40 and thus fold back into a trailing position along the flight 48. Within the core 42 of the cylinder is a stationary bar 44 carrying a number of sprockets 85. Each finger unit 58 also has a sprocket 83 connected to a fixed sprocket 85 by a continuous chain 84 contained between the walls 50, 51 of the flighting 48. As the cylinder 40 rotates, the sprocket 83 carrying a pair of cams 82 also rotates. A cam follower 73 attached to each pivoting finger 62 causes movement of the finger 62 with a positive drive into the operating position and a spring return to the trailing position.  Another embodiment Fig. 10 (not shown) uses discs 237 rather than helical flights and the stationary bar 262 Fig. 21 (not shown) at the cylinder centre carries bushes 308 each with a flange 312 of varying thickness which acts as a double faced cam. A radial torsion rod 319 is connected to the cam 312 by a short spring loaded lever 326 and a cam follower 328 while connection at the outer end to the finger is through a spring-loaded toothed clutch 347. Timing of the finger is adjustable by rotation of the stationary bar 262.  Adjustment is also provided to enable the position of the cutting bar 38 to be moved around the axis of the cylinder 40 by use of spacer plates 297 Fig. 16 (not shown). The cylinder and associated conveying devices may be driven by a hydraulic motor 391 Fig. 12 (not shown) with its own power supply and electronic means of controlling the cylinder speed in direct ratio to the ground wheel speed when the harvester is being towed, the actual ratio being preselectable.
