Title: Improvements in or relating to boiler cleaners
IPC: F28G3/16
Filed: 1919-12-13
Abstract: 161,630. Babcock & Wilcox, Ltd., Kemnal, J., and Henry, J'. Dec. 13, 1919. Cleaning, fluid-pressure processes for. - An apparatus for cleaning soot, &c. from the tubes of water-tube boilers comprises a number of blower units or distributing-pipes such as A, Fig. 1, clipped by means of brackets B to the top row of tubes of the boiler and at right-angles to them. An improved construction of nozzles, valves, and supporting-sleeves is also described. Figs. 7 and 8 show the apparatus applied to a Babcock and Wilcox land type of boiler. Each distributing- pipe A is divided into two separate compartments A<1>, A<2> which register with two internal ports C', C<2> cast in a rotatable valve body C. Integral with the valve body C is a wheel C<3> which can be operated from the ground by a chain. Within the valve body C is a stationary valve member D connected to the steam or compressed air supply by means of the piping F and formed with a central passage having a semi-circular port D<1>. The valve body C is slung from a spring sleevepiece G supported by a bolt H from a lug on the box K secured to the boiler casing, a spring G<1> being interposed between the nut on the bolt and the top of the box K. This spring suspension allows for expansion of the blower unit or movement of the boiler wall in its setting. A stop K<1> on the box co-operates with a stud on the wheel to limit the rotation of the latter to less than 180‹ to the left or right. The wheel is also provided with an indicator marked " Shut " which is in a vertical position when both ports C<1>, C<2> are closed, as shown in Fig. 9. By revolving the wheel C<3> to the right, the port C<2> and the chamber A<2> are brought into communication with the port D'. The cleansing-medium rushes into the compartment A<2> and out of the jet holes of the nozzles A<3> of the chamber A<2> only. thus cleansing the spaces between the tubes along diagonals to the right. This continues until the wheel is reversed and the indicator is again vertical. When the wheel is turned to the left the compartment A<1> and the port C<1> register with the supply port D<1>, and the cleansing-medium rushes from the jets of the nozzles of the chamber A<1> only cleansing the tube spaces along diagonals to the right as indicated by the lines on Fig. 8. As the wheel is revolved, the cleansing-medium issuing from the jets travels in an arc and in certain positions, therefore, moves away from the centre-line of the tube spaces. To overcome this disadvantage each nozzle is provided with a number of jet orifices machined at different angles from the centre hole.

Abstract: 1,041,927. Bearings. SOC. D'ETUDES ET DE RECHERCHES MAGNETIQUES. Aug. 4, 1964 [July 31, 1963], No. 31509/64. Heading F2A. A magnetic levitation supporting device comprises a magnetic rotor 1, Fig. 1 (not shown); a stationary magnetic circuit embracing the rotor 1 and passing through a magnet 5, a yoke 6, a stator 3, a casing 4, an extension 9 of the stator 3 and a yoke 11, and passing through airgaps 8, 10 and 15 formed between an extension 7 of the yoke 6 and the rotor 1, between the rotor 1 and the extension 9 and between the extension 9 and the yoke 11 respectively; a magnetic shunt path which passes through a magnetic member 17 which is connected by a member 16 to the rotor 1, through a pole extension 20 of the yoke 6, the magnet 5, the stator 3, a magnetic member 18 secured to the member 16 and a magnetic member 19 secured to the stator 3, and through air-gaps 21, 22, 23 and 24 formed between the pole extension 20 of the yoke 6 and the magnetic member 17, between the magnetic member 17 and the magnetic member 19, between the magnetic member 19 and the magnetic member 18 and between the magnetic member 18 and an extension 25 of the stator 3 respectively. In use, any displacement of the rotor 1 towards the extension 7 decreases the gap 8 and tends to increase the attraction force in this gap, however, this attraction force is balanced by an increase of flux in the shunt path which is effected by the narrowing of the gaps 21-24 therein. The combined width of the gaps 8, 10 and 15 in the magnetic circuit is constant so that a decrease of flux occurs in the magnetic circuit and the attraction force in the gap 8 is reduced as its width is decreased. In a modification, gaps 22a, 22b, 22c and 24a, Fig. 2 (not shown), of the shunt path are formed between a three-branch extension 17a, 17b, 17c attached to a stator 3a and a three-branch extension 18a, 18b, 18c of a member 16a which is integral with a shaft 2a and between the member 16a and an extension 25a of the stator 3a respectively. Left and right axial movements of the shaft are compensated by two devices arranged as shown in Fig. 3 (not shown).
