Title: Improvements in or relating to internal combustion engine block construction
IPC: F02F1/16
Filed: 1956-05-09
Abstract: 789,650. Cylinder cooling and construction; lubricating. PERFECT CIRCLE CORPORATION. May 9, 1956 [July 7, 1955], No. 14380/56. Class 7(2) Liners 21, Fig. 5, are brazed or screwed to a plate 22 clamped between an engine block 10, Fig. 2, and a cylinder head (not shown) and have shouldered ends 24 seating in shouldered block openings 15. The plate 22 may seat on an out-turned block flange but as shown seats on an inturned flange 16 with the interposition of a gasket (not shown), a further gasket being provided between the plate 22 and the cylinder head which has combustion chamber recesses containing overhead valves. The block side walls 12 follow the form of the liners 21 to provide water jackets which communicate with a cylinder head jacket via plate bores 33. The flange 16 has tappings 26 for studs passing through the plate 22 and the cylinder head to receive holding- down nuts, and tappings 30 in the plate 22 receive cylinder-head screws.

Title: Improvements in tubulous vapour generating, superheating and reheating units
IPC: F22G5/04
Filed: 1956-05-09
Abstract: 783,765. Regulating steam temperature in boilers. BABCOCK & WILCOX, Ltd. May 9, 1956 [May 10, 1955], No. 14394/56. Classes 123(2) and 123(3) A water-tube steam boiler comprises an upright radiation chamber 10 lined with steam generating tubes extending between a water drum 18 and a steam and water drum 16 which is equipped with cyclone separators, for example as described in Specification 526,825. A cyclone furnace 22, for example of the form described in Specification 598,141, supplies hot gases to a secondary furnace chamber 28 disposed at the bottom of chamber 10 and separated therefrom by a tube wall 212 and slag screen 30, 32. The gases flow through the screen and upwardly in the chamber 10 to each side of wing walls 174 formed of .steam generating tubes and projecting into the chamber from its rear wall. Disposed across the upper part of the chamber 10 are widely spaced platens 96, 118 of tubes constituting respectively the radiantly-heated sections of a superheater and reheater. From the top of the chamber 10 the gases flow laterally through a pass locating a convection reheater 124, 126 and then through a turning space 42 and downpass 44 in which are disposed convection superheater sections 102 and 74...77 repectively. The proportioning of the heating surfaces of the superheater and reheater between the radiant and convection stages is such that constant steam temperatures are maintained over a substantial load range. A temperature control range on both the superheater and reheater is obtained by varying the excess air supply to the cyclone furnace, the temperature of superheat and reheat being reduced when required by the use of interstage attemperators, for example of the form described in Specification 656,551. To control the gas temperature in the chamber 10 to prevent overheating of the radiant steam heaters 96, 118, cooled flue gas is withdrawn from the boiler outlet flue by a fan 150 which discharges it through ducts 156, 160 into the chamber, the gas recirculation also being effective to increase the amount of heat available for convection steam heating.

The cords forming the elements may be formed of 840 denier nylon filaments having twists 310Z x 200S. The elongations at breaking point of the longitudinal and unwoven fabrics are nearly equal. In another example, the strands of the unwoven fabric are formed of between 475 and 315 twists Z per metre and the cords are formed of between 435 and 250 twists S per metre. The belt may have a resistance of 370-430 kg. per cm.

Abstract: 682,936. Welding by fusion. BABCOCK & WILCOX, Ltd. June 20,1951 [June 20, 1950], No. 14624/51. Class 83 (iv). A welded joint uniting a ferritic alloy member to an austenitic alloy member includes a stabilized ferritic zone intermediate the members. The stabilizer for the ferritic zone may be columbium, titanium, zirconium, cerium, tungsten, boron, tantalum or vanadium. In one embodiment of a joint operating under high pressure and temperature, as for example in a steam generating plant, a pipe of ferritic steel, 2“ per cent Cr, 1 per cent Mo, is welded to an austenitic steel pipe by a deposit of ferritic steel which may have the same composition as that of the ferritic steel pipe but which is stabilized by columbium. In a modification a ferritic steel pipe 10, Fig. 2, is welded by a deposit 15 of non-stabilized ferritic steel to a stabilized ferritic insert 40 which is itself welded to an austenitic pipe 20 of composition 19 per cent Cr-9 per cent Ni stabilized with Cb; 25 per cent Cr, 20 per cent Ni; or 80 per cent Ni, 20 per cent Cr, by an austenitic deposit 25 having a composition similar to that of the pipe 20 but which may be stabilized with columbium. In a further embodiment a ferritic pipe 50, Fig. 4, has deposited thereon a ferritic steel 55 of substantially the same composition as that of the pipe 50 but which is stabilized with columbium. This deposit 55 is bevelled at 56 to form a groove with an austenitic pipe 60 in which groove is deposited austenitic steel 65 which may have a composition the same as that of the pipe 60 but which is preferably stabilized with columbium. Welding may be effected by the process of shielded metal arc, atomic hydrogen, inert gas shielded arc or submerged arc.

Abstract: 693,868. Heating and cooling pulverulent materials. ALUMINIUM LABORATORIES, Ltd. June 26, 1951 [July 20, 1950], No. 15151/51. Class 64 (ii) [Also in Group XXX] Heat exchange between pulverulent materials and a fluid is effected by maintaining the powders in fluidized state and in flow while contacting heat-exchange elements 25 through which the fluid is circulated. Moreover, a long bed of powder (such as hot, calcined alumina to be cooled by water flowing in the elements 25) is formed around the elements, to be fluidized by upflowing gas and, since the material is fed continuously to the bottom at one end of the bed and withdrawn from the top at the other end where the fluidizing gas is led away, there is a flow of the powder lengthwise of the horizontal bed. Heating or cooling fluid flows in sinuous tube coils 25 suspended in a long, narrow trough A having an air chamber 12 beneath a grating 10a supporting a porous diaphragm 10 through which air from a control valve (not shown) is supplied for fluidizing the powder bed. From a conduit 17 the powder is fed by gravity into a feed bin 16 and flows beneath a gate 18 which is raised or lowered to adjust the flow rate of powder through the trough A. At the other end of the trough the powder flows over an adjustable gate 27, which determines the height of the fluidized bed, into a hopper 28, while the fluidizing gas is carried away through a stack 32.

Abstract: 251,129. Steinberg, E. June 12, 1925. Arc lamps. - A polyphase lamp with parallel carbons, each in series with a ballast resistance, is arranged so that it can be adapted for singlephase or direct-current circuits by switching off or removing all but two of the electrodes 1, 1<1>, 1<11>, Fig. 3, and short-circuiting the resistance 2<11> in series with one of the remaining electrodes. For striking the arc on a three-phase circuit, one of the electrodes may be pivoted so that it can be swung, against the action of a spring, into contact with the other two. Alternatively, a striker may be used, either of pyramid form so that three faces make contact respectively with the three electrodes, or of wedge shape, one face making contact with two electrodes and the other face with the third electrode. The electrodes may be mounted points downward within a shade 19, Fig. 12, the striking lever 10 being actuated by a chain 20 and a spring, or automatically. In an enclosed lamp, the carbon carrier may be inserted from the rear of a rejector into a guide member within a glass bell mounted on the reflector.
