Title: Improvements in and relating to towing winches
IPC: B63B21/56
Filed: 1933-12-19
Abstract: 420,122. Winches ; cooling motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin) Dec. 19. 1933, No. 35744. Convention date, Dec. 20, 1932. [Class 78 (v)] [See also Group XXXV] In towing winches, &c., controlled by an electric motor in order that the motor may be prevented from being held for a long time under current in one position, whereby the commutator will be unevenly and unduly heated, an auxiliary motor is provided which constantly produces a slow movement between the pole casing and the armature of the main motor. In one arrangement the rotatable casing 3 of the main motor is coupled through the gearing 4 to an auxiliary motor 5. The voltage of the Leonard generator 6, Fig. 2, which supplies the motor 3, is controlled by a field regulator 9 which is operated by a travelling nut 10 running on a spindle 11 driven by the winch through a disconnectable coupling 12. The auxiliary motor is switched out in the end position of the regulator, or on rotation over a range which, under working conditions, can only be set up for a short period with a temporary overload or underload. The same result is attained by the provision of a current limiter which switches on and off in direct dependence on the load of the motor 5, or by placing a voltage cut-out across the armature of the motor 3. The motor 3 is cooled by a current of air supplied by a fan 13 driven by the motor 5. In a modification the main motor is coupled directly to one of the free shaft ends of a differential gear, and the auxiliary motor slowly drives the second free shaft end. A self-checking transmission may be placed between the auxiliary motor and the differential. When a Leonard set is interposed, the casing of the main motor, or the third shaft of the differential may be coupled to the set, and the separate auxiliary motor dispensed with.

Title: Improvements in boiler cleaners
IPC: F23J3/02
Filed: 1929-11-23
Abstract: 349,430. Boiler cleaners. FAIRWEATHER, H. G. C., 65, Chancery Lane, London.-(Whittemore, Hulbert, Whittemore & Belknap ; 112, Penobecot Building, Detroit, Michigan, U.S.A.) Nov. 23, 1929, No. 35919. [Class 99 (ii).] In a boiler cleaner, compressed air from a supply tank 16 is supplied to the usual rotatable blower tubes 12 in puffs through a pressure control valve 24 and a puff controller 38. Rotation of the blower tubes is effected by a chain sheave 55 on the heads thereof, and each tube is provided with a cam 63 adapted to open and close a valve 61 in its supply pipe 14. The puff controller 38 comprises a cylinder having inlet and outlet ports leading from and to the control valve 24 and blower tube respectively by pipes 41, 14, and a piston 42, preferably driven by an electric motor 45 having a switch which is closed by the cam 63 whenever the blower is rotated, reciprocating therein to cover and uncover successively the said inlet port. The control valve comprises discs 26 carried by a stem 27 and disposed within a casing having an inlet and outlet 25, 37 respectively, the said discs permitting the passage of air when lifted by the pressure in the tank 16, which acts on a diaphragm 32 mounted in a casing 35 on the valve casing and secured to the stem 27, overcoming the resistance of a weighted lever 28 connected to the said stem. The tank 16 is supplied by a compressor 17 driven by a motor 18 and is fitted internally with a heating coil 22. In operation, and with the air in the tank 16 acting upon the diaphragm 32 to open the valves 26 and permit heated air to pass to the puff controller, the blower tube is rotated and the switch of the motor 45 closed thereby to operate the puff controller. The latter will supply air to the blower tube during rotation of the same or until the pressure in the air tank falls to such an extent as to cause the valve 24 to close. The weighted lever of the control valve may be replaced by a spring, and the valve may be provided with a switch device which operates, when the supply pressure falls, to start the compressor motor 18 and also to actuate a brake to prevent rotation of the blower tube. Slag-removing fluid, such as water or steam, may be fed to the air supply pipe 14 at a point such as 68.

Abstract: 1531491 Seals BRITISH STEEL CORP 8 Sept 1976 [8 Sept 1975] 36876/75 Heading F2B A method of making a ceramic seal 13, for fitting between the end 12 of a ceramic refractory or silicone carbide tube and a ceramic end wall 10 of a recuperator, comprises spirally wrapping a ceramic fibre blanket 20 around a collapsible mandrel 24, radially compressing it to a diameter less than that of the opening in the wall 10, and applying to it, e,g. by impregnation before, during or after winding, a heat fugitive substance such as resin, which holds the blanket compressed to permit installation, but which degrades or evaporates when subject to service heat to allow the blanket to expand and produce a gas-tight seal. The seal 13 is held in the wall by a bayonet ring 14 with interposed ceramic washers 17, 18. In Fig. 3 the ceramic blanket 20 is spirally wound on a combustible former 21, along with an interposed resin-impregnated film 22 which produces the radial compression and is allowed to cure to maintain the compression before the coil is removed from the mandrel. In Fig. 4 (not shown), the blanket is separately wound and compressed as a whole by an external tensioned plastics film. In Fig. 5 (not shown), a resin-impregnated blanket is passed between and compressed by pinch rolls (25) on its way to winding. In Fig. 6 (not shown), a thick ceramic blanket, previously impregnated and cut to length, is wound into a single layer coil. In Figs. 8 and 9 (not shown), only the first layer of a multi-wrap blanket is impregnated, and, after winding, compression is produced by three circumferentially spaced arcuate impregnated wraps anchored on fixed posts (30). The overlaps are resin treated and the surplus cut off.
