Title: Improvements in and relating to domestic water boilers
IPC: F24H1/24
Filed: 1934-03-15
Abstract: 420,566. Combined flreplace and boiler stove. TURNER, I., 19, Warren Avenue, Richmond, Surrey. March 15, 1934, No. 8179. [Class 126] [See also Group XIII] An open grate or fireplace b for heating a room is provided with a back c in which is recessed a boiler a without a cooking stove but with a separate grate k which has no communication with the grate b, so that each grate may be used independently. A firebrick bl separates the grates. The back c has a hinged or removable panel j forming the boiler front so that the room may be heated by the boiler fire. The boiler a extends round the back and two sides a<1> of the grate k but not across the front c, the front edges of the sides inclining forward to the top. Fuel is added to the grate k by turning down a plate w and removing a plate d<2>. The boiler grate is fitted with a loose grid or with bottom rocking bars controlled by rods m, m<1> and a front handle m<2>. A large ash-pan o with a draught-regulator o<3> extends under both grates, and a second ash-pan p above the pan o and below the grate k excludes draught thereto from below. A scraper bar p<4> on withdrawal of the pan p tips ashes into the pan o. The gases from the open fireplace b escape into flues s one at each side of the boiler and thence into a three-way junction fitting t connecting with the outlet q from the boiler fire, each outlet having a separate damper t<2> controlled by a rod from the front. The grates may be coke or gas-fired. A loose ash-tray z is provided. Specifications 23212/07, 1540/08, and 280,035, [all in Class 126], are referred to.

IPC: B21D22/02
Filed: 1920-03-19
Abstract: 155,495. Cain, J. J., and Babcock & Wilcox. March 19, 1920. Steam generators.-Cup or trough-shaped articles, such as are adapted for use in making headers for tubular boilers are stamped from a blank 26, and the sides are subjected to pressure to increase their thickness and that of the angles they form with the bottom. A corrugated die 22 is mounted on the bead of an hydraulic ram 16 and surrounds a die 21 carried thereby, which may engage stops 23 or a lateral part of the head. A pin-and-slot connexion permits relative movement between the die and the head. A female die 20 is arranged on the base 19. The dies 21, 22 first move together to shape the article, the stops 23 are then removed from the die 21, which relatively recedes, the sides are compressed, and the article completely shaped in the final movement of both dies.

Specified values for W are sulphate ester, phosphate ester, chlorine and bromine.  The halogenated polycyclic ketone containing at least three fused benzene rings which forms a part of the condensation product with amino-dibenzanthrone may be derived from benzanthrone, anthraquinone, anthrone, anthanthrone, benzpyrenequinone or pyranthrone.  The dyes are made by condensing dyestuff sulphochlorides, made by sulphochlorinating nitro-dibenzanthrone, aminodibenzanthrone or condensation products of aminodibenzanthrone and halogenated polycyclic ketones containing at least three fused benzene rings and, if desired, aminoanthraquinones or by treating sulphonic acids of these dyes with chloro-sulphonic acid and thionyl chloride, with o -haloalkylamines or the sulphate esters of alkanolamines or with alkanolamines followed by esterification with sulphuric acid, or by reducing the dyestuff sulphonic acids to sulphinic acids and reacting these with b -chlorethyl alcohol or ethylene oxide followed by esterification with sulphuric acid.  Examples are given.  The dyestuffs dye and print textile materials of natural or regenerated cellulose in conjunction with an acid-binding agent and a heat treatment, and also wool and silk in grey shades.

[Class 144 (i).] A machine for making bead cores by winding wire tape on a rotary drum comprises an automatically operated clamp for seizing the end of the tape and applying it to the stationary drum, power means for rotating the drum at variable speeds with a magnetic clutch and brake for stopping the drum after a predetermined rotation, a stitcher disc adapted to operate after stoppage of the drum to consolidate the severed end of the tape, and an axially movable ring for ejecting the built-up core from the drum. The bead tape is drawn from stock rolls through a coating and tubing unit, festooned around adjustably spaced rollers to avoid tension, and then fed to the building drums 26, shown separately in Fig. 13. Each drum comprises a disc 174 bolted to a shaft 164 and formed with a stepped periphery to receive a flanged adaptor ring 184 appropriate to the type and size of bead core required. An ejector ring 190 for unshipping the built-up core is carried by bolts 188 and is normally held up to the flange of the ring 164 by springs 192 on the bolts. The latter are actuated, to displace the ring 190, by members 204 carried by a timed, cam-operated slide 200. In operation, the forward end of the tape 17 is gripped between a serrated block 224, Fig. 14, recessed into the periphery of the disc 174 and a cam-operated presser arm 242, the tape being fed to the gripping means by electrically controlled, fluidoperated devices. An oiling pad is fitted to wipe the surface of the drum for preventing adhesion of the tape thereto. The tape is severed, after completion of the winding, by shear jaws connected by toggles to the pistons of power cylinders. The stitcher rolls 542, Fig. 6, for consolidating the tape are actuated by the pistons of power cylinders 537 which are vertically adjustable in brackets 518 by means of hand-wheels 521. The valves for the cylinders 537 are actuated from a cam drum in timed relation with the main clutch and brake of the building drum.

Abstract: 549,738. Wheels and rollers. BASSICK CO. July 10, 1941, No. 8732. Convention date, Sept. 25, 1940. [Class 144 (i)] A furniture castor has a wheel or roller of plastic material with a cushion adjacent the periphery and a relatively hard thin peripheral floor-engaging portion supported by and flexing with the cushion, the floor-engaging portion having a smooth surface to enable the castor to slip on a carpet or rug. As shown, the wheel may have an interior part 14 of hard rubber encircled by a zone 17 of soft rubber with a thin periphery 18 of rubber slightly less hard than the interior 14. The periphery 18 may be formed by a flexible skin vulcanized to the soft rubber 17 or may be formed by hardening the surface of the soft rubber by a halogen. The periphery is given a smooth, glazed, surface to minimize wear of the fabric when used on a carpet. When under full load, the wheel deforms and engages the supporting surface over an extended area thus avoiding denting of the surface when this is in the nature of linoleum.

Abstract: 939,194. Electrostatic precipitators. H. BRANDT. March 14, 1961 [March 16, 1960], No. 9309/61. Class 117. In an electrostatic precipitator comprising a vertical casing defined by inner and outer walls 4, 3 and divided into sector-shaped chambers 32 through which dust-laden gas is caused to flow upwardly over complementary electrodes 16, 21 and wherein each of the chambers 32 is substantially disconnected separately from the gas flow by means of a dust-discharge duct 6 rotated in resilient sealing engagement with the lower end of the casing and a sealing plate 7 rotated in partial sealing engagement with the upper end of the casing, the assembly 6, 7 being rotated step by step in synchronism with electric-supply cut-off means for the associated electrodes 16, 21, rapping devices 18, 23 are provided for the electrode assemblies 16, 21 respectively operable to dislodge dust therefrom into the duct 6 during the cleaning cycle of each chamber. As shown the duct 6 leads into a hopper 10 and during each cleaning cycle, clean air from the casing outlet 2 is drawn into the chamber being cleaned through the substantially sealed upper end of the chamber to flush any fine dust from the electrodes into the hopper 10. This flushing air flow is induced by a fan 14 which draws the air into a secondary dust collector 12 via a pipe 11 from the hopper 10, the air being eventually discharged back into the dust-laden gas at the casing inlet 1. The rotating assembly 6, 7 may be duplicated on diametrically opposed sides the casing. The electrodes 16 may be anodes of tubular or plate form supported on insulators 17a resting on the rapping devices 18, the cathodes 21 also being supported at their upper ends on insulators 20a and being connected together at their lower ends by a spring mounted and insulated spacer 22. Switching of the electrode supply current may be effected by means of saturable reactors.
