Patent GB-1078571-A (GB)
IPC: F24C3/04
Abstract: 1,078,571. Incandescent gas fires; air heaters. OATLEY TECHNICAL DEVELOPMENTS Ltd. Jan. 3, 1964 [Jan. 3, 1963; March 9, 1963] Nos. 343/63 and 9471/63. Headings F4S and F4W. In a radiant convector gas fire, the products of combustion emanating from the radiant panel pass through a heat exchange chamber, where indirect heat exchange occurs between the products of combustion and convection air, and thence through a vent to the flue, while flueinducted room air flows from an inlet above the radiants directly to the vent without mixing with the products of combustion except in the vent. As shown in Fig. 2, the hot products of combustion rising from the radiants 7 are deflected by an apron 40 into the rear section 28 of a heat exchange chamber 10 where they heat the rear wall 19 of the chamber before passing over a baffle 29 and through the front section 27 of the chamber to a vent 33. Inducted room air passes through an inlet 41 directly to the vent. The backs of the radiants 7 heat a convection air heater 17 to heat convection air which enters through a low grille 14, passes up passage 13, is further heated by the hot wall 19, and is discharged back into the room through an upper grille 15. The convection air path is entirely sealed from the products of combustion path to prevent mixing of the products of combustion with the convection air. The vent 33 is double walled to prevent undesirable heat exchange between the convection air and the mixed products of combustion and inducted air. In one modification, Fig. 3 (not shown), the baffle (29) is omitted and the inducted air entering through a grille (45) passes through a duct (44) through the heat exchange chamber to the vent which has a Venturi nozzle (49). In another modification, Fig. 4 (not shown), the products of combustion flow first to the front portion of the heat exchange chamber and then pass behind a baffle (53) to the vent (52).

Abstract: 1,253,097. Gas turbine combustion chambers. ROLLS-ROYCE Ltd. March 13, 1970 [March 21, 1969], No. 15025/69. Heading F1L. Gas turbine engine combustion equipment comprises an annular combustion chamber 22 having an upstream portion 24 in which are mounted circumferentially spaced radially extending walls 25 defining alternately arranged primary combustion zones 30 and diffusing dilution air passages 31, air being supplied to the chamber through a diffusing inlet duct 21 within which there is located a rotatable assembly of vanes 17 which effect diffusion of the air flowing thereover. Radially extending gutters 33, 40 and a fuel pipe 32 are mounted in each combustion zone 30, air for atomization of the fuel being supplied to the space 34 between the gutters as a radial flow 35 from a generally axial annular cooling air passage 36. The atomized fuel leaves space 34 through gaps 41 between the downstream edges of the gutters and is burnt in the sheltered zone provided by the concave surface 42 of gutter 40. The downstream edges of walls 25 are fluted to promote mixing of the combustion gases from zones 30 with the dilution air from diffusing passages 31. No dilution air holes are provided in the combustion chamber walls 26, 27, the latter being lined with ceramic tiles. The diffusing vanes 17 are mounted on a disc connected to the high-pressure compressor rotor and driven through a shaft 13 by highpressure turbine 14. The assembly of walls 25 and gutters 33, 40 may be fixed but in the arrangement shown the assembly is rotatably mounted on a roller bearing 52 and is driven by air directed thereto by stator vanes 50. Fuel passes under centrifugal force from a reservoir 53 to the fuel pipes 32. The rotation of the walls 25 and gutters &c. ensures that the hot mixed combustion gases rotate relative to the turbine nozzle guide vanes so that the latter are not subjected to high local temperatures.

At station III a synchronously-moving knife blade 10, cuts the top and side walls of the tube without cutting the bottom surface. Individual folding operations are carried out at stations IV to VIII where a series of interconnected frames 13, each carrying a folding member 14, move, at the same speed as the wrapping 1, in an endless guide path 11 each folding member 14 having a shaft 15 with a roller 16 which is urged by springs 12 into engagement with a fixed cam member 18. A folding member 14 is moved between two adjacent articles 5 at station IV to fold portions of the upper tube face 22 against the end faces, Fig. 4, of the two adjacent articles and form triangular side flaps 23 which are then folded inwardly, after the folding member 14 has been raised, by two horizontally movable bodies 19, which arelocated at station V and also synchronously move with the wrapping 1. Blades 46, at the front ends of the bodies 19 cut into the bottom of the tubular wrapping so that the adjacent pair of packages are connected together solely by the flap (1a), Fig. 5, not shown. The folding member 14 is lowered again at station VI so that a blade 20 folds the flap la up into the plane of the bottom surface of the package. A second cutting device 25 at station VII cuts through the flap 1a. The folding body 14 is lowered slightly at station VIII so that the forwardly directed bottom flap 24 is folded beneath the package by a folding member 26 and subsequently sealed thereto. The rear bottom flaps 24 are folded up at station IX the flap being first bent downwardly by a rotary arm 27 and then folded beneath the package by a rotary folding disc 28. The completed sealed package is moved by a conveyor 29 out of the machine. The second cutting device Fig. 9 not shown, comprises a housing (25) which is rotatable to have a peripheral speed equal to the feeding speed of the packages and which has a blade (37), which is raised to project from and housing (25) and lowered again, by a pinion (35) and rack (34) which is reciprocable by cam and lever mechanism (40, 41, 42). A package may contain more than one article.
