Abstract: 868,929. Furnace walls. BABCOCK & WILCOX Ltd. Aug. 30, 1957 [Aug. 31, 1956], No. 27410/57. Class 51 (1). [Also in Group XIII] A gas-tight furnace wall panel comprises finned tubes 1, Fig. 1, welded edge-to-edge along the fins 2, 3. In an alternate construction the fins are tangentially arranged relative to the associated tubes. In the construction of a furnace chamber, welded U -shaped expansionmembers such as 17, Fig. 4, may be used to connect adjacent panels 10, 15, a welded finned tube 21 connecting panels at the chamber corners. Corners may also be constructed by cutting away in a suitable pattern fin parts from a panel such as 26, Fig. 6, and forming apertures in another panel 25 to accommodate the tubes 27 of the panel 26. These tubes may be welded at 28 to stub tubes 33 protruding from a header 32 and the abutment between the panels may be sealed by welding. In a boiler or heat exchanger of the " flame return " type having in a horizontal cylindrical casing 40, Figs. 7, 8, burners 41, 42, projecting flames into an internal duct 43, the latter is formed by curved tube walls 44, 45, which lead from a lower water drum 47 to an upper steam and water drum 46 and consist of finned tubes welded side-by-side along the edges of the fins. After traversing the duct 43 the hot gases reverse and pass through an annular duct 48 surrounding the duct 43 and containing evaporator tube nests 49, 51, and superheater tube nests 55 and 50. The nest 51 contains evaporator tubes 52 leading between the drum 47 and a chamber 53 leading to the drum 46. Steam from this drum is conducted to the superheater 55 through a header 56. Except for the portions opposite the superheater tubes 50, 55, which are formed of refractory 59, the outer wall of the duct 48 is also formed from welded sideby-side finned tubes.

Title: Improvements relating to the treatment of multi-ply sheets of cardboard and the like for the manufacture of boxes or packages
IPC: B31F1/28
Filed: 1930-09-15
Abstract: 362,537. Cardboard &c. boxes. RAINSFORD, C. F., 2, Currajong Avenue, Camberwell, Victoria, Australia. Sept. 15, 1930, No. 27490. [Class 18.] In making tubular boxes with end-closing flaps from multi-ply cardboard &c. sheets comprising two flat layers with an intermediate corrugated layer, the joint between the meeting edges of the tubular body is formed by removing a portion of the intermediate corrugated layer from between the outer layers at one edge of the sheet to form a gullet for the reception of the opposite edge of the sheet, the separated outer layers being spread or turned substantially at right-angles to the plane of the sheet before being gummed and pressed on to the edge inserted between them. As shown the multiply sheets 2, Fig. 4, are temporarily folded to facilitate their passage through the machine in which the gullets are formed, Figs. 1 and 2, the sheets being fed in a vertical position to belts 19 by hand or by conveying means comprising upper and lower belts having plates 31 between which the sheets are placed and by which they are carried across the machine bed 10 until engaged by one of a series of projections 28 on an endless chain 29 which then conveys the sheet along the bed until it is gripped by the belts 19 which are carried by rollers 17 on vertical spindles 18. A verticallydisposed circular saw 51 is mounted beneath the belts and removes a portion of the corrugated layer 4 from between the outer layers 6 as the sheet is fed forward. The side faces of the saw may be provided with inclined bosses which effect an initial spreading of the separated layers 7 which then engage a spreader 56, Fig. 7, by which the layers 7 are turned out at right-angles to the sheet 2. The layers 7 then pass below parallel guide-plates 61 which ensure contact of the layers with a gumming roller 57 and feed rollers 62 carry the gummed sheet between guides 63 which support the gummed edges clear of the machine bed; the gulleted and gummed blank may then be placed on the table 83 for the completion of the box joint. The fold 8 in the sheet is accommodated in a U-shaped guideway 13 in which may be mounted a roller 16 to press the sheet down on to the circular saw ; an inclined guide 66 ensures the sheet passing between the rollers 62 from the guide-plates 61. The gumming roller and associated parts may be mounted as a detachable unit on the machine bed and the conveyer belts and guiding means may be adjustably mounted to accommodate sheets of different sizes ; the feed rollers &c. are driven from a shaft 73 geared to the shaft of the saw 51 which is driven from a motor 71.

Filed: 1955-09-28
Abstract: 805,128. Gas turbine plant. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Sept. 14, 1956 [Sept. 28, 1955], No. 27600/55. Class 110 (3). In an aircraft powered by a plurality of groups of gas turbine engines with their lines of action spaced from one another, each group of engines drives in common at least one fuel pump which is connected to supply fuel to at least one engine of each group. The aircraft shown, Fig. 2, is powered by thirty-two gas turbine jet propulsion engines, sixteen in each wing arranged in four groups of four, i.e. A1 to A4; B1 to B4; C1 to C4; and D1 to D4 with their lines of thrust parallel. The four engines of each group are arranged close together and may be wholly or partly structurally integrated with one another. The engine intakes are connected to the interior of a hollow main spar 6 through non-return valves (not shown). The interior of the spar is also connected through passages formed between the upper and lower wing surfaces and an inner fairing with a long shallow slot at the leading edge of the wing. The engines discharge through jet pipes 14 to nozzles 14a which extend along the span of the wing. The engines A1, A2, A3, A4 drive a common fuel pump 21 through shafts 22a, 22b, 22c and 22d, free-wheel devices 26a, 26b, 26c, 26d and bevel gears 23a, 24a, 23b, 24b, 23c, 24c and 23d, 24d. The pump 21 is connected to supply fuel through pipes 27, 27a, 27b, 27c and 27d to one engine of each of the four groups, i.e. engines A1, B1, C1, D1. The groups of engines B1 to B4, C1 to C4 and D1 to D4 each drive a fuel pump 28, 29, 30 which is similarly connected to supply fuel to at least one engine of each group. In a modification, the fuel pumps 21, 28, 29, 30 are driven by small air turbines supplied with air bled from the compressors of the engines, each air turbine being associated with a particular group of engines. This turbine may be driven by combustion or exhaust gases from the engines. The fuel systems for the engines in opposite wings may be cross-connected. The invention may be applied to lift jet engines, or to engines driving propellers. The number of engines in each group may be made equal to the number of groups or greater than this, in which case some of the fuel pumps may supply fuel to a different number of engines than others. Two fuel pumps may also be driven in common by each group where the number of engines in each group is twice the number of groups. Specifications 758,269 and 787,012 are referred to.

A heel H of plastics material is attached to a shoe upper A by applying a polyurethane adhesive in fluid, foamable reactive state and an organic solvent capable of dissolving the plastics material of the heel, to the heel seat portion of the heel and maintaining the heel in position on the shoe upper while the adhesive is reacting to provide a stiffened, foamed polyurethane bond between the heel and the shoe upper. The organic solvent may be applied to the heel before the polyurethane adhesive is applied or may be applied in admixture with the polyurethane adhesive. The heel may be held in position while the adhesive is reacting by a screw applied by a -screw inserting means D of the type described in Specification No.607,345. The adhesive is applied to the heel by an attachment to the screw inserting machine. Adhesive is stored in a plastic container inside a box B, the container having a flexible outlet tube 20 which is housed in a tubular guide 16 having a slot 18. Adhesive is squeezed -from the tube 20 on to the heel by a roller 34 which is pressed against the tube 20 by a roller on the piston rod of pneumatic cylinder 42 and is moved downwardly by the piston rod 30 of pneumatic cylinder 28. The polyurethane adhesive is produced by the reaction of a polyisocyanate with a polyhydric alcohol, a polyester polyol or a polyether polyol, there being an excess of free or unreacted isocyanate groups which will react with moisture to cause the adhesive to expand. Preferably the adhesive is the reaction product of polyethylene glycol and polymethylene polyphenylisocyanate. The adhesive may also include extenders and fillers such as sulphur, ground cork, clay, glass fibres, wood pulp, foam glass, gypsum, aluminium silicates or hydroxides or synthetic polymers such as polyvinyl chloride or polystyrene. Suitable solvents capable of dissolving the plastics material of the heel are aromatic hydrocarbons such as toluene, xylene, cumene, chlorinated hydrocarbons such as ethylene chloride, ethyl benzine, chlorobenzine, ethylene dichloride, carbontetrachloride, chloroform, benzyl chloride, chlorotoluene, as well as n-butyl acetate, cellosolve acetate, dimethyl foramide. When the heel is made of acrylonitrile-butadiene-styrene copolymer the solvent is preferably ethylene dichloride.

A circuit assembly comprises a stack of insulating cards, each carrying a plurality of separate conductors some of which have been interrupted by punching, conductors on adjacent cards being inter-connected to form a three-dimensional circuit. The cards described are of plastic material and of a size suitable for perforating in punched card accounting machines. Fig. 9 shows a partly cut-away view of a stack of such cards, alternate cards baving parallel strips of conducting material positioned respectively to correspond to the rows and columns of the accounting cards. At each indexing or punching position a projection is formed on either side of each conducting strip extending to the surface of the card. These projections 13 provide connections between conductors in corresponding positions on adjacent cards of the stack. Holes such as 41 are punched to isolate sections of any conducting strip. Holes such as 34, 35, 36 are provided where it is necessary to insulate a conductor such as 29 from corresponding conductors on an adjacent card such as 37, 38, 39. The projections 13 are tinned before assembly so that inter-card connections are made when the complete stack is bonded together under heat and pressure. Components such as 32 may be soldered or welded to projections 13. In another embodiment the conductors are disposed on one surface of each card as in Fig. 10. Small holes 48 are made at each index position, the inside of the holes in the card being metallized as described in Specification 829,789. The cards are stacked with an insulating card 49 interposed between each pair. A hole is punched in the insulating card where it is desired to connect conductors on adjacent cards. Solder pellets 53 which will fuse during the bonding process, are inserted at each inter-card connection. In Fig. 11, the holes 48 and the insulating card 49 are omitted, inter-card connections being made by milling wells 57 in the insulating portion of each card to enable solder pellet connections to be made as before.

Abstract: 1304747 Hydrostatic transmission POCLAIN 9 June 1970 [11 June 1969] 27766/70 Heading F2D In a hydrostatic transmission having a low speed mode of operation in which two variable delivery pumps 3a, 3b supply through separate lines 7a, 7b and forward-reverse valves 6a, 6b two groups of motors 1, 2 having a common return line 8 including a variable orifice 9 that prevents overspeeding of the motors and a high speed mode of operation in which the output of both pumps is combined by a valve 31 and supplied to the motors 1 alone whilst the motors 2 freewheel, the return flow from the motors 1 during high speed operation passes through the motors 2 to cool and lubricate the latter and thereafter passes through a variable orifice 15 which acts in conjunction with the orifice 9 to prevent overspeeding of the motors 1 during high speed operation. The orifice 9 is controlled by the higher of the supply pressures 7a, 7b which acts through a shuttle valve 42 on the orifice 9 to increase the size of the orifice with increasing supply pressure. The orifice 15 is controlled by the pressure in the return line 8 which reduces the size of the orifice as the return line pressure increases. An auxiliary pump 17 supplies control pressure to a control valve 26 which in the position shown conditions the circuit for low speed operation. When the valve 26 is changed over the control pressure is supplied through lines 28, 29 to a servo 30 which changes over the valve 31 to supply the combined output of the pumps to the motors 1. In addition the control pressure changes over a valve 39 to connect the line 7a to a reservoir 4. The control pressure is also supplied through lines 28, 32 to servos 33 which condition the motors 2 for freewheeling.
