Title: Improvements in or relating to tubular heaters
IPC: F24H1/40

Abstract: 919,229. Fluid heaters. BRENNAN, F. A. Nov. 16, 1961 [Nov. 22, 1960], No. 40033/60. Class 64 (1). The base a of a vertical tubular fluid heater is provided with intercommunicating cross-passages t for connection to a fluid supply and apertures y between the said passages to serve either as inlets for hot gases from a burner or for mounting electric heating elements in the heater. Two mutually perpendicular passages t are drilled through the base-plate a and communicate, through five holes x drilled vertically in the plate, with vertical copper water tubes 6. The passages t extend to the periphery of the plate and are connected to legs m, one of which incorporates a T-connector w for connection to a water feed valve n. Four further holes y are drilled through the base-plate between the passages t to allow heating gases from an oil or gas burner to pass into a cylindrical space z to heat the tubes b which extend through this space and a top-plate c to a removable frusto-conical outlet header f. Radial outlets l are provided in a fire-brick sleeve d defining the space z and communicate with vertical gas-vent tubes i. The header f and fire-brick sleeve d are surrounded by insulation c and metal casings, the casing for the cylindrical part of the heater extending below the base-plate a to form a burner chamber k. The tubular legs n may also serve as dirt pockets and be fitted with blowdown or drain cocks.

Abstract: 1438659 Colour picture tubes STANDARD TELEPHONES & CABLES Ltd 21 Aug 1973 [30 Aug 1972] 40122/72 Heading H1D The screen 21 of a colour picture tube has on its inner surface ribs 2 between which are strips of phosphor deposited on coloured filters R, B, G which run perpendicular to a row of electron guns and the ribs are shaped so as to permit by parallax only electrons from one gun to reach each phosphor strip; thus beams 14, 16 can only excite the phosphor behind red filter R and the phosphor G behind the green filter respectively. Instead of using phosphors and coloured filters different colour emitting phosphors can be used, Fig. 3 (not shown). A black matrix screen can be made by separating the phosphorus with non-emitting material. The screen can be made by applying the rib structure as a pre-formed piece of glass on a tube faceplate to which it is bonded and then annealing the screen structure.

Abstract: 1287824 Rolling METALLURGIE HOBOKEN-OVERPELT 25 Aug 1970 [25 Aug 1969] 40802/70 Heading B3M In a continuous rolling process for copper bar there are provided means between the stands of a group of roughing stands B to reduce tension in the bar, and the stands of an intermediate group of stands C are arranged so that their passes suppress torsion along the bar. The temperature of the bar is kept constant before it enters the roughing stands by a temperature measuring and controlling device 8, which may heat or cool the bar 800-850‹ C. The copper bar is continuously cast and passes cooling nozzles 2 and pinch rollers 3 driven slower than the bar feed speed. The bar is bevelled by milling cutters 4 and cleaned by metal brushes 5. The speed of the first roughing stand 9 is controlled by a bar supporting device 7. The device comprises a pair of pivoted parts 49, 50 equipped with rollers and biased upwards. The weight of the bar normally holds the parts in the horizontal position but if the supported bar lengthens it permits upward movement of the parts and increase in the speed of the stand 9. The group of roughing stands B includes similar supporting devices 10, 13, 18, 21 so that at least the first two roughing stands are preceded by a supporting device. The devices serve to reduce or eliminate the bar tension in the stand. The roughing stands are alternately horizontal and vertical and may have square, rectangular, oval or round passes. The intermediate group of stands C also comprises alternate horizontal and vertical stands with free loops 23, 26, 28 &c. of bar therebetween. Alternatively the stands may be alternately inclined at 45 degrees. The passes of these stands are all oval or alternately oval and circular to suppress torsions. The free loops are supported on plates when the stands are inclined. The shaped bar is finally cooled in a device 42 to a temperature dependent on the required properties for drawing, e.g. between 700-800‹ C. or between 300-600‹ C. The bar may be descaled, rinsed and coated before being wound. The rolling train is lubricated with oil and housed in a protective atmosphere. Emergency shears 6, 11 &c. are provided along the train to cut the bar if necessary.

In a method and apparatus, Figs.2 and 3, for conditioning, subdividing and cleaning harvested sugar-canes, the canes are fed, through a hopper 1, on to the upwardly inclinded, upper flight of an endless, travelling conveyer 2, which conveys the canes through a plurality of rigid, rotating arms 4 mounted on a rotating shaft 3, which arms distribute the canes in an even and thin layer on the upwardly inclined, upper flight of an endless, travelling conveyer 5, e.g. a rubber-belt conveyer, preferably travelling at high speed. The arms 4 detach leaves from the canes. The canes are conveyed, by the conveyer 5, through knives 6 mounted on two shafts rotating in opposite rotational directions, which knives cut the canes into short pieces, and detach impurities, such as dirt. The pieces of cane pass into a winnowing chamber 10, through which air, from a blower 7, is blown through a nozzle 9. Air containing impurities is discharged from the chamber 10 through an exhaust part 11. Cleaned pieces of cane pass through a doorway 12, in the base of the chamber 10, on to the upwardly inclined, upper flight of an endless, travelling, conveyer 13, and are thus conveyed to a deflector 14, which distributes the cleaned pieces of sugar-cane into a vehicle 15, in which they are transported to a sugar mill.

Abstract: 1409314 Transformer tap-changing systems SMIT NIJMEGEN ELECTROTECHNISCHE FABRIEKEN NV 7 Sept 1972 [7 Sept 1971] 41635/73 Heading HIT An on-load tap changer for a regulating transformer comprises (i) an off-load tap selector having one set of switching contacts 10 connected to the even tappings of the regulating winding B and the other set 11 connected to the odd tappings; (ii) a diverter switch C1 with two fixed main contacts 12, 13 directly connected to the selector switching contacts 10, 11, and at least two fixed auxiliary contacts 14, 15 which are contacted in succession by a switching contact 16; (iii) transition impedances 19 and 20, and (iv) an auxiliary changeover system 18, 21, 22 which connects these transition impedances with one of the main contacts 12 of the diverter switch, the arrangement being such that during changeover as the movable contact 16 passes from one fixed contact 13 to the other, 12, via auxiliary contacts 15, 14, the values of impedance brought into circuit as the auxiliary contacts are engaged decreases. This is effected in the embodiment shown by mechanically coupling the changeover contacts 18, 21 and 22 and connecting two impedances 19 and 20 in parallel in the manner shown, so that with contact 22 connected as shown the auxiliary contact 15 is connected to the higher impedance 20, the movement of the diverter switch being from main contact 13 via 15 and 14 to 12. Thus throughout the sequence the branch circuit interrupted carries less current than that newly closed. For reverse movement the three contacts 18, 21 and 22 are simultaneously changed over. Figs. 3 to 8 (not shown) illustrate several variations, both simple and more complex, in which up to five auxiliary contacts may be used in the diverter switch together with seriesparallel arrangements of similar individual impedances and modified auxiliary switching arrangements to provide the required ascending order of impedance circuits.
