Title: Improved apparatus for cleaning fluid heaters such as boilers
IPC: F28G7/00
Filed: 1941-07-01
Abstract: 550,355. Cleaning boilers &c. BABCOCK & WILCOX, Ltd. July 1, 1941, No. 8259. Convention date, Aug. 14, 1940. [Class 99 (ii)] [Also in Group XXIX] Soot or other combustion residues are removed from the heat-transfer surfaces of a boiler or other fluid heater by apparatus operating outside the gas space and inducing impulses or vibrations in the gases in, contact with the residues to be dislodged. Fig. 1 shows one form wherein air or steam under pressure in a chamber 12 is admitted in successive blasts to an outlet 21 leading by a pipe line to the boiler space, by means of a rotating valve 17 formed with ports 16 cooperating with corresponding ports in the valve casing 13. In Fig. 3, a valve 29 seating at 31 is intermittently opened by the action of the fluid pressure in a chamber 26 on the end face 43 of the valve, a spring 34 closing the valve again when the pressure has fallen sufficiently. As soon as the valve begins to open and pass a blast of fluid through a pipe 32 to the boiler space, the fluid pressure acts on the whole face 29 of the valve to effect a rapid opening. In another form a diaphragm or a movable section of the boiler wall is vibrated to and fro by eccentric or other driving-means, so as to set up vibrations in the gases within the boiler.

Title: Photographic camera, particularly moving picture camera
IPC: G03B7/06
Filed: 1956-03-16
Abstract: 812,074. Photographic cameras. HANDLER, A., and VOCKENHUBER, K., [trading as EUMIG ELEKTRIZITATS-UND METALLWAREN INDUSTRIE]. March 16, 1956 [March 18, 1955], No. 8263/56. Class 98(1) In a photographic or kinematographic camera, a light intensity indicator which is used to control the camera setting consists of a detachable unit, and all lightweaking members affecting its indication are mounted on the camera. As shown in Fig. 1, the iris diaphragm 1 is controlled by means of a milled knob 2 coupled to the diaphragm by gear wheels 3, 4. Gear wheel 4 meshes with a gear 7 journalled on a common shaft 8 with a cam 9 in a lever 18 pivoted about the shaft of the gear wheel 4. The light intensity indicator consists of a block 14 carrying a light-sensitive cell in front and enclosing a meter with a pointer 28 visible in a window 27. The indicator 14 is detachably located in front of a light tunnel 16, the entrance 17 of which may be more or less closed by a pivoted flap 13. The flap 13 is connected to a crank handle 11 which bears against a sliding member 10 acting as a follower to the cam 9. The amount of light reaching the cell 15 is therefore varied in accordance with the setting of the diaphragm 1, and cam 9 is so constructed that the correct setting of the diaphragm is obtained when the needle 28 of the meter is brought into registration with a fixed mark 29. Differences in the speed of the film passing through the gate of a kinematograph camera may be taken into account by rocking the lever 18 about the shaft of the gear wheel 4. To this end, the lever 18 carries a mark 19 which may be brought into registration with one of a number of marks 20<SP>1</SP>, 20<SP>11</SP>, 20<SP>111</SP>, according to the film frame speed. The emulsion speed of the film may be allowed for by restricting the available area of the cell 15 by means of flexible blinds 26 which are movable by means of a disc 22, which may be set to a desired film emulsion speed by means of a scale 21. The disc carries an eccentric pin 24 entering a slot 25 of a slide connected to the blinds 26. A plane mirror 30 may be placed below the cell at such an angle that the pointer 27 may be viewed by transmissive light through the eye-piece 31 of the view finder, the parts being so positioned that the image of the pointer is formed at the same position as the image of the scene.

Title: Improvements in or relating to the manufacture of coal gas
IPC: C10B27/06
Filed: 1928-03-19
Abstract: 312,727. Rees, E., and Gardiner, G. March 19, 1928. Hydraulic mains. - Gas making retorts delivering to a common hydraulic main are controlled separately by dividing the main into separate compartments on the intake side, a single chamber being provided on the outlet side, the intake compartments being partitioned off from the common outlet compartment so as to provide separate adjustable seals for the several intakes. The pressure to which each retort is subjected may be varied according to any cycle of operations. Each ascension pipe a connects with a dip pipe b<1> which extends to the level of the liquor in a hydraulic main d, a curtain plate f<1> forming a cleaning chamber f from which extends the gas off-take g<1> leading to the foul main g. The front portion of the main d is divided into as many compartments c as there are dip pipes b<1> by vertical partition plates c<1>. Openings f<2> between the compartments c and the chamber f are controlled by slide valves h connected by rods h<1> to levers i having toothed quadrants j meshing with pinions k on a control shaft operated by a hand wheel l<1>. At the beginning of the carbonizing period, by releasing a clamping screw k<1>, the pinion is set so that the bottom of the valve h is just at the surface of the liquor. As carbonization proceeds the vacuum due to the exhausting fan is diminished by rotation of the shaft t which increases the depth of seal of the valve in the retort concerned in stages during the carbonizing period. During discharging and charging of the retort the pinions k are disengaged from the shaft l to permit the corresponding levers i and valves h to be lowered, whereby a deep seal is maintained. Specifications 191,226 and 302,437 are referred to.

Filed: 1974-02-25
Abstract: 1466951 Furnace shells ENGINEERED METAL PRODUCTS CO Inc 25 Feb 1974 8473/74 Heading F4B A furnace shell comprises a dish-shaped bottom section 22, Fig. 1, having a metal casing 28 and a refractory lining 30, a first generally ring-shaped wall section 24 removably mounted on top of the bottom section and a second ring-shaped wall section 26 removably mounted on top of the first, each wall section having a casing and refractory lining, and means on the easing for holding the refractory lining so that the lining can be installed before the wall section is mounted in place. The furnace may be for melting steel scrap, heat being provided by electrodes extending downwardly through the roof section which is not shown in Fig. 1, and the furnace is adapted to tilt on the rounded bottom portion 34. The middle wall section 24 flares outwardly and the top wall section 26 tapers inwardly so that the furnace has a barrel-like section bulging outwardly in the middle. The bottom section casing 22, Fig. 2, has an outwardly projecting flange at its upper edge to be engaged by the lower flange 50, Fig. 3, of the middle wall casing 24. The upper flange of this casing is similarly engaged by the lower flange 84, Fig. 4, of the top wall casing. The casings are located on each other by pins 52, 86 engaging in holes in the superposed casings. The joints between the refractory linings are sealed with fireclay. The metal easing 62 of the pouring spout is removable from the middle wall easing as shown in Fig. 3 being normally retained by flange bolts and locating pins in the top flanges 70. The middle wall section 24 has a stepped upper surface constituted by flanges 72, 80. By this means the joint between the middle and top wall sections is arranged always to be above the slag line 56 even when the furnace is tipped. Also the stepped construction facilitates insertion of the firebricks during installation of the linings in the two wall sections. When wear necessitates the shutting down of the furnace the worn wall sections 24, 26 are removed and spare ones are hoisted into place. The refractory linings are held in place on the wall sections when these are detached from the furnace bottom by ledges 90, Fig. 3 and 92, 94, Fig. 4. Opposite the pouring spout there is a slag discharge opening 100 formed by a sill 112 in the middle wall and an opening in the top wall, Fig. 4, lined by side members 104, 106 and a top member 108. The opening 100 can be closed by a sliding door 102. When the furnace is tilted backwardly slightly the slag pours out through the opening 100 and flows over a refractory apron 114, e.g. of graphite. The door 102 is carried in a water-cooled metal frame. Cooling water is also circulated through passages 120, 134 in the upper and lower flanges of the top wall casing. Similar passages may be formed in the middle wall casing.
