Patent GB-189826406-A (GB)
Title: Improvements in and connected with the Supply and Withdrawal or Liquid to or from Filter Beds, and in Filter Bed Construction.
Inventor: ADAMS SAMUEL HENRY
Filed: 1898-12-14
Granted: 1899-07-15
Abstract: 26,406. Adams, S. H. Dec. 14. Filters, supplying and discharging liquid to.- Consists of siphon apparatus for the supply and discharge of sewage or other liquids to or from filter'beds, and of an improved pipe for bringing sewage to the filter beds. Fig. 1 shows a siphon arranged to discharge the liquid from a filter bed after the latter has been full for a given time. When the liquid reaches its upper level, the float valve k is opened, allowing the slow discharge of air trapped in the cover j. Liquid thus eventually enters the cover j far enough to raise the float m, which by means of the rod n and trigger h allows the float valve f to open and discharge the trapped air from the cover b, thus starting the siphon a. Fig. 2 shows a siphon for supplying a a filter bed A. With the liquid at a low level in the vessel A', the siphon a does not start until the air pipe g is open. The opening of the pipe may be controlled by the separate device shown in Fig. 4. The pipe g dips into a vessel o, the liquid level in which is raised to d by the liquid displaced from the bell b, by the air compressed in the bell o' as liquid rises around it, the bell o<1> being fixed in a tank such as A. The rate at which the liquid level now falls in the vessel o, and therefore the time at which the pipe g is uncovered, depends on the adjustment of the valve f. A series of filter beds may be arranged so that, on one becoming empty, the air pipe g of the supply siphon of another filter bed is uncovered, and the latter filter thereupon filled, the filters being discharged by siphons of the kind shown in Fig. 1. Or the air pipes of the discharge siphons of a series of filters may be similarly arranged. The open end of the pipe g may be enlarged as at h<1>, so that a greater quantity of air may belocked within the pipe. The siphon may be arranged to revolve in its tank, and so connected with a float in the tank that, each time the float rises, the siphon is turned so as to supply a different filter bed. The sewage is conveyed to the filter bed in a number of small pipes or channels, instead of in one large one, so as to break up the solid matter carried by the sewage.

Abstract: 2327. Pease, E. L. Feb. 2. Sheds.-Instead of using split tubes for connecting the edges of the plates or sheets together as described in Specification No. 21,331, A.D. 1896, grooved bars or beams a, preferably of wood, are employed, and the edges of the sheets b are secured in the grooves by wedges or laths c. Fig. 2 shows a bar for a hollow roof or wall. Wood tongues b<1>, nailed to the strawboard sheets, enter recesses in the bars, and transverse stretchers d lock the wedges in the rece3ses beneath the sheets. Fig. 3 shows a flanged metal sheet b secured to the recessed bar by a wedge c. Transverse saw cuts may be made in the sheets and bars to receive metal tongues, or the wood strips b<1> nailed to the sheets may be retained in the recesses in the bars by metal strips e, Fig. 5, inserted in cuts in the bars. The joint may be caulked with lead wire f. Instead of nailing strips to the sheets, bent spikes or staples may be driven into the ends of the sheets so as to engage with the strips e. The edges of plain or corrugated metal sheets or plain felt sheets are secured in the recessed beams by transverse supporting-bars and wedges, and the beams may be protected by sheet-metal strips or sheathing. In the arrangement shown in Fig. 10, a strip of steel e<1> nailed to the side of the bar a enters a saw cut in the inside sheet which is of the same width as the outside sheet.

Patent GB-189908520-A (GB)
Title: Improvements in Apparatus for Automatically Closing Water Tight Doors in Ships.
Inventor: FAIRWEATHER WALLACE
Filed: 1899-04-24
Granted: 1900-04-24
Abstract: 8520. Fairweather, W., [Thomson, C.]. April 24. Bulkhead doors; companions.-Relates to means for automatically closing bulkhead, companion, and other water-tight doors in the event of water entering the ship. The invention is shown in Fig. 3 as applied to a horizontally-sliding door, but is equally applicable to vertically-sliding or hinged doors. In the deck E, on each side of the bulkhead G, is a valve C closed by a spring. Any water flowing over the deck opens the valve C and falls down the pipe D into the cylinder B. The piston A is thus moved to the right, and by means of the rod H rotates the wheel K<1> and pinions K<4> gearing with racks on the door X, which is in this manner closed. Previous to moving the piston A the water enters the cylinder I, and raises the piston I' to release a clutch K which locks the door in the open position. The movement of the door is controlled by a piston L' which forces a fluid from the cylinder L into the cylinder L'. The door is opened by admitting water from the sea to the cylinder by means of a valve B<5> operated in the manner shown from either side of the bulkhead. Before the valve B<5> is opened, the valve C<8> is opened and C" shut by a hand-lever which also holds the clutch K disengaged. The door may be closed by a falling weight, or by its own weight in the case of a vertically-sliding door. In these circumstances the piston A withdraws catches or stops to allow the weight or door to fall. In the case of a hinged door, it is mounted on a screwed spindle which is rotated by the piston A when water enters the cylinder. The piston A, instead of directly actuating a horizontally-sliding door, may control the admission of compressed air to the door-operating cylinders, or the supply of electricity to a door-operating motor.

Abstract: 17,114. Graham, J. Aug. 23. Vapour burners.-The oil chamber A is supplied by a pipe B and cock B', a perforated chamber R packed with asbestos or the like being supplied with oil by a pipe M and cock M', and the two being connected by a central tube E. Upon igniting the oil in the chamber R, the chamber A is heated and the vapour escaping from the apertures D<1> is ignited. Vapour escaping through the perforations K<1> to the central tube is also ignited, and the flame is supplemented by oil and air supplied respectively through the holes F, F<1>. After a time, the supply of oil to the chamber R is discontinued, and that to the chamber A is regulated to suit the requirements. By supplying to the chamber A sufficient oil to overflow at the apertures D' and run down through the holes C<1> to saturate the asbestos in the chamber R, the oil-supply pipe M may be dispensed with.
Patent GB-189920328-A (GB)
Title: Improvements in or relating to Dynamo-electric Generators or Transformers.
Inventor: ROBISON JOHN KEELER
Filed: 1899-10-10
Granted: 1900-03-10
Abstract: 20,328. Robison, J. K. Oct. 10. Converting alternating and direct currents; transformers.-Relates to machines which may be used for converting single or multiple alternating currents into unidirectional currents, or vice versÔ. The invention consists essentially in winding the field magnets of a generator in such a manner as to produce an alternating polarity, and exciting them by means of alternating currents, while the armature is rotated at such a speed that the number of field poles multiplied by the number of revolutions per minute is equal to the number of alternations per minute of the exciting current. Fig. 1 shows a simple form of the apparatus, consisting of a bipolar generator A in combination with a bipolar alternating-current exciter B. The field coils a of the generator are connected in series with the armature c of the exciter, while the shunt and series field coils b and f of the exciter are connected with the armature g of the generator and with the supply mains n, n<1>. Both armatures may be mounted on the same shaft, or their shafts may be geared together, so as to ensure synchronous rotation, and the armatures are rendered capable of angular adjustment relatively to each other by mounting them on sleeves secured to the shaft by set-screws. A secondary battery E, arranged in a branch circuit, may be employed for starting, or it may be used for exciting the generator when it is required to supply alternating currents. Switches r and m are provided for throwing in or out the battery and exciter respectively. The machine for converting multiphase alternating currents into unidirectional currents or vice versÔ consists, for example, of three dynamos in combination with a three-phase alternating-current exciter, the armatures of which are all mounted adjustably on the same shaft, the dynamo armatures being set at angles to one another equal to the differences of phase between the fields. The field coils of the three dynamos are connected in three-phase relation with the armature of the exciter, while the three armatures are connected in series with one another and with the field of the exciter. This organization exercises a regulating- influence upon the unidirectional currents supplied to the mains.

Title: Improvements in or relating to Berths for use on Board Ship.
Inventor: CHRISTIE THOMAS
Filed: 1899-12-01
Granted: 1900-11-17
Abstract: 23,935. Christie, T. Dec. 1. Berths.-Fig. 1 shows one method of suspending a berth. A bracket 1 bolted to the ceiling has universally jointed to it a frame 2 to which four rods 7 are universally jointed. A rod 3, universally jointed to the bracket 1, carries a grooved wheel running between the frame 2 and a bar hinged to it. This arrangement prevents the berth from oscillating. The rods 7 are universally jointed to the berth 8 and to a frame 9, which is similarly jointed to a bracket 10 bolted to the floor or side of the cabin. The berth proper 8 is narrower and shorter at the bottom than above, to clear the walls of the cabin when it swings. In a modification, the frame 9 is placed over the berth, immediately under the frame 2. 5 is a casing secured to the wall and containing catches which lock the berth in a horizontal position. A similar casing may be fitted at the other end of the berth, and also similar ones 6 at the sides. Fig. 2 shows a portion of the casing 5 in vertical section. Catches d, d engage hinged tongues i, i on a frame h swivelled on the frame 2, and hold the berth in a horizontal position. As the vessel rolls or pitches, these catches are automatically disengaged to allow the berth to maintain a horizontal position. Should the casing move out of the position shown, one or other of the swinging catches c, c tumbles over and frees the lever d resting on it. This lever then turns up clear of the tongue i, and allows the berth to swing. A further movement of the vessel releases the next catch-lever d, and so on. Springs g return the levers after the tongues i have passed them. The catches c are prevented from tumbling, except when the tongue presses on tho corresponding lever d, by a cord or by a hook secured to the lever. Modifications in the arrangement of the levers and catches are described.

Title: Improvements in Vapour Burners
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1900-04-18
Granted: 1901-04-06
Abstract: 7201. Thompson, W. P., [Braun, F. W.]. April 18. Vapour burners.-In atmospheric vapour burners for use with metallurgical and like furnaces in which the flame is enclosed, or for purposes in which the flame burns in the open air, the Bunsen or mixing tubes are formed with internal fittings which ensure a more perfect admixture of the air and vapour, and are provided with a supplementary starting and igniting device. When the bunsen tube or burner b is for use with enclosed furnaces, the internal flange 3, with its curved inner and plane outer faces 5, 6 for retarding the escape of the mixed air and vapour, is arranged near the discharge-end of .the tube. This construction allows the admixture of a greater quantity of air with the vapour than when the internal flange 3 is placed at some distance from the discharge-end, as is done when the burner is for use in the open air, the additional air being supplied in this case at the point of combustion. The vaporizer a is arranged at the discharge end of the burner, and the jet or orifice d is arranged at such a distance from the inlet-end of the tube b that the vapour jet, as shown by the straight lines in Fig. 6, spreads sufficiently to fill the contracted end of the internal cone 2. The supplementary starting and igniting device is shown in Fig. 2, a secondary jet e on the supply tube c discharging into a trough f, which has perforations g, g<1> for the admission of air near its inlet end, and its outlet adjacent to the vaporizer a and the discharge end of the main burner. When the valve k is opened, the escaping hydrocarbon is ignited in the trough f, the flame heating the vaporizer a and igniting the vapour which escapes from the main burner as soon as the jet d is turned on. If desired, this secondary jet can be employed while the main burner is alight, to assist in the heating of the vaporizer. Owing to the thorough mixture of the air and vapour, the main flame is of practically uniform temperature throughout its cross-section.
