Patent GB-189901034-A (GB)
Title: Manufacture of Indoxyl-methylketone.
Inventor: IMRAY OLIVER
Filed: 1899-01-16
Granted: 1899-11-04
Abstract: 1034. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. Jan. 16. Indoxyl derivatives. - Relates to the process described in Specification No. 9690, A.D. 1898, and consists in producing indoxyl derivatives by acting upon esters of aromatic o-amidocarboxylic acids, which contain the group attached to the nitrogen atom, with metallic sodium or sodium alcoholate. The compounds employed may be prepared by acting upon o-amidocarboxylic esters with halogen-acetone, halogen-acetaldehyde, #-halogen-acetophenone, or the like. The only important products are the acetonylanthranilic ethyl or other esters obtained by acting upon two molecular proportions of an anthranilic ester with one molecular proportion of halogen acetone, or by using equal molecular proportions of these compounds and a reagent capable of combining with hydrochloric acid. The action of sodium upon acetonylanthranilic ester is to produce indoxyl-methylketone, which is a pale yellow substance having the melting point 153‹ C. It forms a hydrazone with phenylhydrazine, and yields chloroform when acted upon by an alkaline hypochlorite. Dyes, artificial.-Indoxyl-methyl ketone is converted by heating it with caustic alkali into a yellow mass, the aqueous solution of which when exposed tu the air yields a precipitate of indigo.

Title: Improvements in Electric Maximum Demand Indicators.
Filed: 1899-05-02
Granted: 1900-05-02
Abstract: 9245. British Thomson-Houston Co., [Cox, F. P.]. May 2. Current meters.-Maximum-demand indicators for multiple-wire systems are constructed to be influenced by the currents in all the supply wires except the "neutral wire," so that their indications are proportional to the maximum total load at any time. A thermal overflow instrument for a threewire supply is illustrated, having two heating-coils H, I in the outer wires. Equality and adjustment of effect of the two coils is obtained by shunting them by adjusted resistances J. A clockwork indicator may be similarly provided with two coils in the outer wires, acting together to deflect a magnetic needle. An arm of the needle may then make contact with a pin on the indicating- pointer of a clockwork, thus closing a circuit containing an electromagnet, which frees the escapement of the clockwork, allowing it to run until the pointer leaves the arm of the magnetic needle.

Patent GB-190105791-A (GB)
Title: Improvements in and relating to Electric Incandescent Lamps.
Inventor: FESSENDEN REGINALD AUBREY
Filed: 1901-03-19
Granted: 1901-10-19
Abstract: 5791. Feasenden, R. A. March 19. Incandescent lamps.- An incandescence rod 8, of magnesia, kaolin, or other material conducting only after preliminary heating, is rendered conductive by an electric heater, which may consist of one or more metal strips 7, curved about the rod 8, and backed with non-conducting material; the ends of the rod may also be heated by surrounding wire coils 17. Alternating current is supplied to the rod and heaters by one or more transformers, wound and arranged so that, when the rod 8 is not conductive, a high pressure is applied to it, and current is supplied to the heater, but when the rod is conducting its normal current the heating- current is reactively reduced or stopped. These devices and a switch are all placed in the lamp casing, and may be arranged for supply with either constant pressure or constant current. Fig. 9 shows a constant pressure arrangement with four transformers 1, 14, 12, 12. The principal heater 7 is in series with coils 3, 13, and with the primary coils of two transformers 12, which supply the end heaters 17. The rod 8 is in series with coils 4, 15. When the rod is conveying its normal current, the coil 15 causes the transformer 14 to neutralize the action of the transformer 1 in the heater circuit. In modifications, the two end transformers 12 may have a single core, with open magnetic circuit ; or the end heaters may be supplied from independent coils on the main transformers 1, 14. The main heater may be connected with the supply mains, through a coil on the neutralizing-transformer 14. On a constant current supply the transformer 14 is dispensed with, the rod and heaters being connected directly to the coils 4, 3 of the supply transformer ; the wires supporting the incandescent rod may be held apart only by wax or other fusible non-conductor, which melts and allows the wires to short-circuit the rod if it fails to operate when the heater is in circuit. A long series of lamps may be divided into groups, which are started successively by current supplied through wires connected between the groups and to a hand or automatic switch. Similar supply arrangements may be used,with incandescence rods on which are heating-conductors that become non-conductive when the rods become conductive.

The corresponding pairs of pistons H are united by webs h. slotted at the centre to receive sliding blocks g<1> and crank-pins g secured to cranks connected to a shaft G, the cranks being arranged at right-angles. The slots in the webs h are recessed at the centre to allow play of the blocks g<1> and thereby permit cushioning of the liquid at the ends of the stroke. The ends of the cylinders communicate, by ports b, b<1> and passages in a port block F, with crescentshaped ports f arranged concentrically about the face of the block. This block is kept in position by the upper part D of the casing and a dowel pin p. Against the port face works a valve L, provided with an annular recess or pocket l and mounted on an eccentric tumbler M on the shaft G to permit alteration of the relative positions of the wearing-faces of the valve and ports. An annular port f<1>, formed in the block F, is arranged to keep the recess l and the exit passage Q for the liquid in communication. The water enters through a pipe N and strainer n into a chamber P, and, after passing through the cylinders, is delivered through the passage Q. The valve L moves relatively to the ports f in such a manner as to bring each port alternately into communication with the space P and with the pocket l. The rotation of the shaft G is transmitted by worm gearing R and a shaft to suitable counting and recording. mechanism E. Upon removing the part D, by breaking the joint at d, the whole of the mechanism is open to inspection and may be removed without interfering with inlet and outlet connections.

Abstract: 26,028. Ladislaw, H., and Sgal, L. Dec. 20. Feedwater, controlling.-A cylinder containing a reciprocating piston is arranged in connection with the boiler at about the normal water level so as to be flooded when the water rises too high. The movement of the piston is thus checked or prevented, and, by means of suitable connections, the supply of water to the feed-pump is cut off, or the movements of the pump itself are checked. Fig. 1 shows an arrangement of apparatus of the first kind, Fig. 2 being an enlarged view of the cylinder in section. The piston c within the cylinder b is reciprocated by a crank j operated by connection to the feed-pump or other moving part of the engine, a telescopic spring connection being interposed at p. When the water level in the boiler a rises above the dotted line 1-1, the piston cannot rise, and the feedvalve m, to which it is connected by the chain and lever shown, remains closed by the action of a spring. When, however, the water level falls, the piston can rise and fall freely, and the valve m is opened at each stroke. In the arrangement shown in Figs. 6 and 7, the cylinder b is arranged horizontally, and the piston c is connected directly to the feed-pump. The cylinder has connections s, t to the boiler, so as to be flooded when the water level rises, the movement of the piston c, and hence of the pump, being thereby prevented.
