Abstract: 1,240,791. Cooling electric machines. SIEMENS A.G. 15 Jan., 1969 [20 March, 1968], No. 2483/69. Heading H2A. In an electrical machine, having a salient pole rotor 3 which, on rotation, will draw a cooling gas flow from outside the rotor and through the spaces between the salient poles 4, a non- magnetic screening means is disposed at one end of the rotor so as to cover, entirely or for the greater part, both one axial end of the spaces between the poles and the same axial end of the machine air gap 5. This is to reduce impulse exchange ventilation losses and as shown comprises a cylindrical cover 10 fixed to the stator 1 and an annular screen 8 fixed to the rotor hub 7, the cooling air being supplied through hub apertures 9 and discharged through stator core radial ports 6; the stator winding 2 is cooled by water passing through ducts. There may be a similar means at the other end of the rotor, and in other embodiments the screen 8 has fan blades (12), (14) on its outer or inner surface, the cover 10 has apertures (15) to permit cooling of the stator winding overhang (11), and the screening means may be stationary.

Title: Improvements relating to tubular heat exchangers
IPC: F28F11/00
Filed: 1969-01-17
Abstract: 1,260,725. Tubular heat exchangers; heating air by waste gases. BABCOCK & WILCOX Ltd. 17 Jan., 1969 [17 Jan., 1968], No. 2794/69. Heading F4S. A heat exchanger comprises a casing 18 containing tube banks interconnected in series for a fluid flowing through the tubes, the first bank in the series (i.e. that nearest the fluid inlet to the tubes) being divided into tube groups each individually removable from the heat exchanger through an access opening in the casing. The construction is particularly concerned with air heaters in which the air is heated by hot flue gases flowing over the tubes, the removable tube groups being adjacent the air inlet 15 to the  tubes where corrosion of the tubes mainly occurs.  In the air heater shown in which tube banks 10, 11, 12 are arranged in the casing 18 having a flue gas inlet 17 and outlet 19, air to be heated passes into the tubes of the lowermost bank 10 through the inlet 15 and then flows via headers 13 and 14 through the remaining tube banks to a heated air outlet 16. The tube bank 10 consists of separate tube groups 23, Fig. 2. These can be uncoupled and individually lowered by a movable hoist 26 into a dust hopper 20 disposed below the tube assembly and having at one side 21 thereof a door which can be opened to permit removal or replacement of the tube unit. In another form (Figs. 3-10) the tube bank adjacent the air inlet, instead of spanning the gas duct in a single length, is divided into two  portions (32, 33) each comprising a plurality of individual tube groups, the portions being separated by a connecting means enabling individual tube groups of either portion to be removed and replaced via the door in the casing. The connection means between the portions 32, 33 comprises either a header (34) from which the tube plates (38, 39) of the respective portions can be unbolted, or a joint consisting of a support plate (46, Fig. 10) apertured to receive the opposed tube ends of the two portions, in this case projecting from the respective tube plates 38, 39.

Title: Regulation of forced-flow once-through steam generators
IPC: F22G5/00
Filed: 1962-01-25
Abstract: 929,856. Fluid-pressure servomotor control systems. SULZER FRERES S.A. Jan. 25, 1962 [Jan. 27, 1961], No. 2884/62. Class 135. [Also in Group XIII] In a forced-flow, once-through steam generator for steam at supercritical temperature and, at least, critical pressure and comprising vaporizing and superheating sections 16, 22 fed by a pump 26 through a conduit 28. feed valve 67 and economizer 24, control of the fuel supply to the furnace or, as shown, of the feed water supply is effected by taking a sample of steam from the point 50, reducing its pressure to a subcritical value to form a two-phase mixture of liquid and vapour and effecting control in response to the proportions of liquid and vapour in the mixture. One method of control consists in allowing the mixture, the pressure of which is maintained constant by valves 52, 56 under control of a pressure sensor 54, to flow into a separator 62, measuring the separated steam and water flows by instruments 64, 68, and comparing these flows in a comparator 72 which provides a signal to control the feed regulator 66. A second method consists in the use of a wetness detector 74 which provides a signal for the regulator 66. As shown, a fuel valve 44 and air damper 46 are controlled by an instrument 42 responsive to the temperature of the steam at the outlet of the superheater 22, and the regulator 66 is subject to a correction by a device 76 responsive to the temperature of the steam at the point 50. In a modification, the regulator 66 also controls a valve by which water is injected at a point between the vaporizing and superheating sections, and this valve may also be controlled by the temperatures between the vaporizing and superheating sections and at the outlet from the latter.

The block b is pressed home by a screwed plug h the intervening space being first filled with a rubber compound so as to fill any crevices and the entrance to the hole d, so as to prevent access of electrolyte to the wire e. The plug h may have means for turning it which are broken off or removed when finally adjusted so as to prevent unauthorized withdrawal. Two blocks c are dovetailed together so as to form a cell having an electrolyte space ! i between the electrodes communicating with the outer electrolyte, in which the blocks are immersed by an aperture j at the bottom and by laterally cut-away parts slightly above the normal liquid level at the top.

Abstract: 750,269. Sealing bale ties. TEMPLE VELOCITY EQUIPMENT, Inc. Feb. 1, 1954, No. 2921/54. Class 146(2) A tool for sealing bale ties comprises a frame, a pair of opposed levers 24 pivoted to the frame intermediate their ends and each provided with a jaw 25, a rod 13 slidable in the frame, means for supporting an explosive charge 40 at one end of the rod, means supported by the frame for detonating the charge to drive the rod across the frame, and means connecting the rod to the levers for swinging the jaws first toward each other and then away from each other as the rod travels across the frame away from the detonating means. Levers 24 pivoted on pins 16 extending through side plates 3, 4 space series of stationary jaw bars 22 fixed to pins 16, the side plates and bars 22 having notches 18, 23 to receive seals 19 surrounding strap 20. A toggle system comprising links 26 and plates 28 is actuated by link 33 to first close the jaws, which are finally closed when block 14 on rod 16 is in the central position, and then opens the jaws again. Vertical ribs 31 on the outermost plates 28 and the ends of pin 36 connecting links 32 to block 14 slide respectively in slots 32, 37 in the side plates. The construction shown in Fig. 3 has two barrels 1, 2 and the cartridge holder 41 is inserted in the effective barrel, being a sliding fit, limited in movement by an outward flange, and attached by means of a screw cap 12 which causes the holder to push rod 13 so that the seal is gripped between the jaws. The cartridge is fired by striking the firing pin 42, whereupon the rod moves through the sealing position to one in which block 14 reaches the other barrel, to which the cap 12 &c. is then attached for the next sealing. operation. To prevent damage to the tool by firing when no seal is in position, the firing cap and cartridge holder are normally held apart by resilient means, e.g. spring-pressed plungers 48, so that the cartridge cannot be struck by the pin, the ports being brought into position for actuation only when a seal is inserted in the jaws, forcing rod 13 and the cartridge holder outwardly against the plungers. The tool shown in Fig: 6 can be fired at one side only, the actuating rod 51 normally being forced to the left by spring 56, and being forced to the right, or active position, by means of a push-rod, and held in this position by the insertion of a seal between the jaws.
