Abstract: 1411275 Burner assembly JOHN ZINK CO 19 Oct 1972 48264/72 Heading F4T A liquid fuel burner assembly comprises a burner tile 11 having an opening 14 therein, a hollow regenerative tile 21 positioned substantially upstream of the burner tile 11 and having an external cross-section smaller than the opening 14, an atomizer 32 within the regenerative tile 21, circumferentially spaced vanes 44 rotatably mounted about the regenerative tile 21, means for rotating the vanes, and openings 36 in the upstream end portion of the tile 21 for admission of air devoid of circumferential motion imparted by the vanes 44. An annular member 42 prevents air which has passed between the vanes from entering the openings 36 whose area is controlled by a movable ring 38. The regenerative tile 21 comprises a ceramic liner (22), Fig. 3 (not shown), supported within a metal casing 23 attached to a front plate 24. A substantially disc-shaped ceramic member (25) has an outer diameter less than the inner diameter of the liner (22) so that there is an annular opening (27) between the two. A plurality of circumferentially spaced ports 28 allows entry of air into the tile 21. The means to rotate the vanes 44 comprises a sprocket chain 47 trained about sprocket wheels 46 mounted at the end of shafts 41 which also carry the vanes 44, one of the shafts 41 having an extension 52 which is rotated by a lever 53. The burner assembly is mounted on and between a furnace wall 10 and a wall 16 which also defines a wind box.

Title: Condition responsive system

Filed: 1962-12-21
Abstract: 988,106. Temperature alarms. SPECIALTIES DEVELOPMENT CORPORATION. Dec. 21, 1962 [Jan. 3, 1962], No. 48374/62. Heading G4N. [Also in Division H3] A temperature responsive system comprises an element having an electrical resistance which varies in response to temperature variations from a normal value, a monitoring device responsive to a first predetermined value of resistance for giving an indication a predetermined time after the resistance passes through the value; and an inhibiting device which prevents the indication being given if the resistance reaches a second predetermined value in less than the predetermined time interval. As described, the system comprises a trigger circuit 12 in which transistor 32 is normally conducting and transistor 34 normally cut off. With a slow variation in resistance of the temperature sensitive element 10, due to a rise in temperature, the bias on the base of the transistor 32 changes to switch it off and charge capacitor 54. After a time determined by the capacitor charge circuit, transistor 34 becomes conducting operating relay 35 to initiate an alarm over contacts 52 and to open contacts 72. A further rise in temperature switches off transistor 55 in a second trigger circuit 14, but transistor 56 is prevented from conducting by the open contacts 72 in its collector circuit. With a rapid change in resistance of element 10, due to a fault condition, trigger circuit 14 switches before relay 35 operates and transistor 56 conducts clamping the base of transistor 34 so that relay 35 will not operate and no alarm is initiated.

Heading C3R. Polymers contain repeating units (O) wherein Ar 1  and Ar 2  are aromatic radicals each containing 4 free bonds in two ortho-related pairs and R 1  is an -NH 2  or hydrocarbonoxy radical. They are prepared by reacting a dianhydride (M) O(CO) 2 Ar 1 (CO) 2 O with diaminodiamide or -diester (N) R 1 CO(NH 2 )Ar 2 (NH 2 )- COR 1 . Below 100‹ C. in a polar organic solvent the polymer (O) is formed; at 100-250‹ C. (P) is formed; above 250‹ C. the polymer (R) is formed when R 1  is -NH 2 . The stages (P) and (R) may be formed directly or via the preceding stage(s). The polymers may also be prepared by fusing (M) and (N) e.g. at 220-300‹ C., then at 300-370‹ C. under reduced pressure. Suitable amino compounds (N) include 4: 6-diamino - isophthalamide, 2: 5 - diaminoterephthalamide, 3: 7 - diamino - 2: 6 - naphthalene dicarbonamide, and 4: 4<SP>1</SP> - diamino - 3: 3<SP>1</SP>- diphenyl - or - diphenylmethane - or - benzophenone-dicarbonamides, and the corresponding methyl or ethyl esters.

In examples 4: 4<SP>1</SP>-diamino-3: 3<SP>1</SP>-diphenyl dicarbonamide is fused with pyromellitic anhydride at 235‹ C., then at 350‹ C. under 0À2 mm. Hg.; the same diaminodiamide is reacted with pyromellitic anhydride or benzophenone tetracarboxylic dianhydride in dimethyl formamide at room temperature, then under reflux and finally under reflux in acetic anhydride; 2: 5 - diaminoterephthalamide is reacted with pyromellitic anhydride in the same way; and 4: 4<SP>1</SP>-diamino-3: 3<SP>1</SP>-di(ethoxycarboxy)diphenyl is reacted in a similar way with pyromellitic anhydride in dimethyl acetamide, the product being ammonolysed before the final condensation. The products may be used in fibres, films and varnishes when of high molecular weight (inherent viscosity # 0À5 at 30‹ C. in 0À5 wt. per cent DMF solution) and containing units (O) or (O + P); lower polymers of these units may be used to impregnate e.g. glass cloth, or metal, carbon, asbestos fibre fabrics then be cured to a polymer of units (R).

Title: Combustion apparatus

Abstract: 1507530 Gas turbine combustion apparatus GENERAL MOTORS CORP 10 Dec 1975 [12 Dec 1974] 50580/75 Heading F1L [Also in Division F4] Combustion apparatus, e.g. for a gas turbine engine comprises a housing (10), Fig. 1 (not shown) containing a liner 4 having a convergent-divergent portion defining a throat 22 between a fuel introduction zone and a combustion zone 66, a combustion air inlet upstream of throat 22 being provided with a centrebody 32 surrounded by two sets of swirl vanes 35, 36, the body 32 having a passage 34 for additional non-swirling air controlled by valve plug 102 in response to the pressures of combustion air and fuel. An intermediate annular wall 30 separating the sets of vanes 35, 36 is composed of rings 50, 51 defining a circumferential fuel manifold 52 connected by axial grooves 54 to tangential ports 55 downstream of a step 56. Thus the swirling air-flow leaving vanes 36 atomizes the fuel issuing through ports 55, further atomization being provided downstream of wall 30 by the swirling air leaving vanes 35. The latter impart a greater swirl than vanes 36. Additional fuel may be supplied via tangential ports 64 from a manifold 59 surrounded by a cooling air jacket 62. Further primary air is added to the swirling fuel/air mixture downstream of throat 22 via ports 65 which also constitute an aerodynamic flame holder. The flame front thus lies downstream of ports 65. The sudden enlargement as divergent section 23 opens into combustion zone 66 causes a toroidal vortex in the latter with upstream recirculation along the liner axis. The non-swirling air introduced through centrebody 32 opposes this recirculation to prevent the flame from striking back into the fuel injection region. Valve plug 102 controlling the non-swirling air is actuated by a motor (108), Fig. 2 (not shown) comprising a diaphragm (111) subject on one side to the fuel pressure in supply pipe 58 and on the other side to'a spring (118) and the combustion air-pressure communicated via port 119 in hollow actuating rod 103. The plug 102 is normally open but closes when fuel pressure falls during engine deceleration. Pilot fuel may be supplied through a pipe 126 within rod 103 to an injection nozzle 124 carried by plug 102. The combustion gases leaving zone 66 flow through a restriction 67 provided by barrier ring 26 into dilution zone 68 where cooling air is added through ports 83, 84. Cooling air is also added through ports 74 in barrier ring 26 after being guided over the surfaces thereof by internal baffle rings 78, 79. Control of air-flow through ports 74, 83, 84 is effected by an axially movable sleeve 82 having ports 87. Primary air control can be effected by a valve 38 having a hub 39 rotatable about centrebody 32 and having spokes 42 which can block the flow passage entrances between the blunt leading edges of swirl vanes 35, 36.
