Patent GB-189726675-A (GB)
Title: Improvements in the Manufacture of Derivatives of the Naphthalene Series.
Filed: 1897-11-15
Granted: 1898-08-27
Abstract: 26,675. Abel, C. D., [Actiengesellschaft f³r Anilin Fabrikation]. Nov. 15. #-Oxy-a-naphthoquinone and its sulphonic and nitro derivatives are produced from #-naphthoquinone derivatives by means of sulphuric acid. For example, #-oxy-a-naphthoquinone is formed by acting upon #-naphthoquinone monosulphonic acid (1 : 2 : 4) with sulphuric acid of 66‹ BÚ. at 25‹ C. for 8 to 10 hours while constantly stirring the mixture, and it is precipitated upon pouring the mixture upon ice. A #-oxy-a-naphthoquinone sulphonic acid, in which the sulphur group is probably in the #2-position, is produced by acting upon #-oxy-a-naphthoquinone with priming sulphuric acid, containing 25 per cent. of free anhydride, at 20‹ C. until a sample is soluble in water, and the acid is precipitated by pouring the mixture upon ice and adding concentrated common salt solution. The sulphonation may be effected without previously isolating the #-oxy-a-naphthoquinone. By acting upon #-naphthoquinone monosulphonic or upon 1 : 2 : 4-amidonaphthol sulphonic acid at below 50‹ C. with a mixture of sulphuric and nitric acids a nitro-oxy-a-naphthoquinone is formed and it is precipitated by pouring the mixture upon ice.

Patent GB-189729412-A (GB)
Title: Improvements in Apparatus for use in ascertaining the Position of Submerged Wrecks and other Bodies, and in Raising the same to the Surface, and for use as a Floating Dock.
Inventor: O'CONOR MAURICE MARY JOSEPH OW
Filed: 1897-12-11
Granted: 1898-12-03
Abstract: 29,412. O'Conor, M. M. J. O. Dec. 11. Submarine explorations, apparatus for making; sunken ships and objects, raising ; docks. - Relates to improvements in apparatus of the kind described in Specification No. 27,047, A.D. 1897. Radial arms 2, fixed to the cylinders 1, bear on the sea bed while the chains 5 are hauled in, and maintain the cylinders in the relative position shown while the sunken ship 6 is raised clear of the bed. The cylinders are then rotated by chains which pass round pulleys 9, and are led under the vessel 6 to winches on the attendant steamships. The sunken ship can thus be raised above the cylinders, and, on pumping water out of the latter, the former is raised above the surface of the water for repairs &c. Additional radial arms 2<A> may be fixed to each cylinder, and may be connected by chains 8* to winding- apparatus 2<B> of the opposite cylinder. Circumferential hoops 45 of the cylinders carry antifriction balls which bear against the sunken ship and prevent injury to it when the cylinders are rotated: Fig. 26 shows a modification of the winding-apparatus. A larger number of pulleys 14 are used, and are mounted on axles one above the other. The casings 16 are mounted on ball bearings 37, and are guided by horizontal rollers 39 and vertical rollers 36. Fig. 29 shows an arrangement in which wire ropes are used instead of chains, and each pair of cylinders is cast in one piece 34. The central portions of the axles are supported by bearing-plates 16<a>, and rollers 36 running on a guide-way 35. Instead of making the cylinders stationary and the rams movable, the rams may be made stationary and the cylinders movable. The chains between the cylinders are supported by buoys until they are in position, and are released by withdrawing ropes which pass between guide-pulleys of the buoys, and under pulleys attached to the ends of rope loops which pass through the chains and are fixed to the buoys. The apparatus may be used for floating vessels over sand banks, or for dry-docking them for examination and repairs.

The mantle-carrier may also be arranged outside the mantle.
Patent GB-189816382-A (GB)
Title: Improvements in Tools for Cutting or Trimming Boiler Tubes.
Inventor: MORRISON JOSEPH COLLIN
Filed: 1898-07-27
Granted: 1899-06-10
Abstract: 16,382. Morrison, J. C. July 27. Pipe cutters.-The tool is for cutting off the projecting ends of boiler tubes 23 preparatory to fixing them as shown, or for cutting out disused boiler tubes. The cutting-wheels 4 are mounted in blocks 3, which may be pushed out through openings in the sleeve 1 by a wedge 33 with undercut grooves engaging with the inner ends of the blocks 3. The wedge is advanced and rotated by a screw 17 with handle 40. The screw passes through a nut 14, which is held stationary by a piece 20 attached to it by a set-screw. The piece 20 has legs 21 for bearing against the tubeplate 24, and a leg 22 for bearing against a rod &c. 25 inserted into one of the other boiler tubes to prevent rotation. The stationary nut 14 is formed with a flange 13, and has a collar 15 fixed to it. Between the flange and collar turns the flanged collar 7 screwed to the sleeve 1. Antifriction balls are inserted between steel rings placed between the flange of the collar 7 and the flange 13.

Title: Improvements in Automatic Water Heaters.
Inventor: MILLER WILLIAM LAURENCE
Filed: 1898-08-10
Granted: 1898-11-19
Abstract: 17,285. Miller, W. L., and Simpson, H. P. Aug. 10. Water-heaters, gas.-Cold water entering through the pipe 6 circulates through the coil 1, which is heated by the gas burners 34, and is drawn off through the pipe 6<a>. The ends 5<a>, 5<b> of the coil are circular, while the remainder is preferably elliptical in cross-section. There is a burner tube 30 arranged in the centre of the ring cf burner tubes 33, and all of these have crescent-shaped burners 34 and air-supply openings 35. The gas valve 22 is carried by the spindle 21 attached to the diaphragms 12,18, the latter of which separates the gas chamber 25 from the upper water chamber 13, which is in communication with the inlet by means of the pipe 6, port 15, and very small channel 16. The lower water chamber 14 is connected to the outlet pipe 6<a> by the unrestricted port 17, and unlike the upper chamber 13 is subjected to the sudden variations in pressure. When no water is being drawn off, the valve 22 is closed by the spring 23 and the differential water pressure on the diaphragms 12, 18. When hot water is being drawn off, the pressure in the chamber 14 falls, and the practically constant pressure in the chamber 13 presses down the diaphragm 12, opens the valve 22, and supplies gas to the burners, which are lighted by the pilot burner 38. In a modification, a piston is substituted for the diaphragms.

Granted: 1899-08-19
Abstract: 21,125. Mechan, H., and Muirhead, D. Oct. 7. Signals, electric.-Relates to electric signalling- apparatus applicable for use as an order telegraph on board ship or elsewhere. The spindle of the receiver A, Fig. 1, is provided with a pointer working over a dial bearing the orders, and is rotated, with a step-by-step motion, by the electrically-operated pawl and ratchet mechanism I, J, H. This mechanism is duplicated in opposite directions, the direction of movement of the pointer depending on which of the two operating- magnets L is energized. The apparatus may be operated by means of pushes at the transmitting- station, or by the transmitter shown in Fig. 3. In this, the wires g<1>, g<2> of the electromagnet circuits are connected respectively to contacts g<3> on the front and back of the teeth g on the wooden or other insulating-disc G. The contact-spring f<1> on the transmitting-lever F normally lies in a diagonal position between adjacent teeth g, so that, when the lever is moved to the left, it makes contact with the front contacts g<3>, and, when the lever is moved to the right, it makes contact with the back contacts. In this way, the circuit of one or other of the magnets L is completed according to the direction of movement of the lever F. The transmitter is also provided with a pointer working over a dial, and may be combined with the reply receiver. A bell or bells are included in the signalling-circuits, and two bells of different tones are preferably employed for ' ahead' and 'astern' signals.
