Title: Improvements in the Manufacture and Production of Phenyl-glycinecarboxylic Acid and of Derivatives thereof and of Intermediate Products relating thereto.
Filed: 1900-03-27
Granted: 1901-01-19
Abstract: 5763. Lake, H. H., [Farbwerk M³hlheim vorm. A. Leonhardt & Co.]. March 27. Phenylglycine-o-carboxylic acid and its esters, and nitriles, amides, and thioamides related thereto are produced from anthranilic acid by the following processes :-(1) A nitrile, which is represented by the formula C6H4.(NH.CH,.CN)COOH, is produced by acting upon anthranilic acid with hydrocyanic acid and formaldehyde successively, or less profitably in the reverse order, or simultaneously. Examples are given in which the nitrile is prepared from anthranilic acid, potassium cyanide, and formaldehyde in aqueous, acetic-acid, and alcoholic solution, respectively. (2) An acid amide is produced by allowing the nitrile to stand with concentrated sulphuric acid for about a day, and then pouring the mixture upon ice and precipitating the amide by soda. (3) A thioamide is produced by acting upon the nitrile with ammonia and excess of yellow sulphide of ammonia, and subsequently boiling off the sulphide, filtering, and precipitating the thioamide by addition of hydrochloric acid to the filtrate. (4) Phenylglycine-o-carboxylic acid is obtained by boiling the nitrile, or one of the original solutions containing it, with caustic soda as long as ammonia comes off, and then acidifying with hydrochloric acid. The product is suitable for use in the manufacture of indigo. Saponification of the nitrile by an acid instead of an alkali is not so satisfactory. (5) A neutral methyl or ethyl ester of phenylglycine-o-carboxylic acid is produced by heating the nitrile with methyl or ethyl alcohol and sulphuric acid, or hydrochloric acid, and subsequently evaporating off the excess of alcohol and precipitating the ester by excess of cold sodium carbonate. (6) An ester of the nitrile is produced by heating an alkaline solution of the nitrile with alcohol and ethyl bromide in a closed vessel (7) The nitrile ester is converted into an acid amide by acting upon it with concentrated sulphuric acid, and subsequently pouring the mixture into ice-water. (8) The acid ester of phenylglycine-o-carboxylic acid is produced by boiling the nitrile ester, or the amide of the nitrile ester, with hydrochloric acid at the inverted condenser.

Title: Improvements in Electrical Water Heaters.
Inventor: HILL HARRY MCDONALD
Filed: 1903-05-05
Granted: 1903-06-18
Abstract: 10,180. Hill, H. D. May 5. Heating water.- An electric heati n g - apparatus is attached to a watersupply tap, so as to furnish a stream of hot water. In Fig. 2, an insulating-block 11 is screwed to the water tap by means of a cap 9, and has a flanged part 12 connecting to a terminal 8, and tc an inner cylindrical metal electrode 13, at the base of which is fixed a. distributing-block 14 of insulating-material. An outer cylindrical metal electrode 17, surrounds the inner electrode 13, but is not in contact with it. Water descends from the supply pipe through openings in the parts 9, 11, 12, and down the centre of the inner electrode to the distributing- channels 15, in the block 14 shown in Fig. 6. Thence it passes up channels 16, and between the inner and outer electrodes, to be discharged through passages 18 into an outer chamber 25, which discharges it finally at the base. The outer electrode 17 forms the bottom and side walls of the passages 15, 16 in the distributing-block, and it is fluted on its outer surface. An upper ring 20 attaches the outer electrode to the block 11. An opening 26 in the outer casing 25 prevents any possible back pressure on condensation of steam. Fig. 7 shows terminals 23, 8 connected to outer and inner electrodes, and passing to a switch 6, automatically operated when the water supply is turned on. A modification in the shape of the electrodes is also shown in Fig. 7, the inner electrode 13 being conical in shape and the outer electrode 17 fitting with it. Thus the size of the water passage between is adjustable, by screwing the outer electrode in or out of the ring 30, and so the rate of discharge of water, and consequently its temperature, may be varied.

Abstract: 16,982. Justice, P. M., [Cambridge Manufacturing Co.]. Aug 4. Balls.-The golf ball shown in Fig. 1 is constructed with a core made of a nitrocellulose compound,such as celluloid or smokeless gunpowder, or other elastic material heavier than water. The core is formed with long and short radial perforations a, a<1>, so that the completed ball has about the same specific gravity as water. A casing B of guttapercha or other material is then applied. This covering may be dispensed with, the ends of the perforations being stopped with plugs of the same material as the body, or of other material. In a modification, the perforations may cross each other at right-angles in three directions. An inner rubber or other casing may be placed between the core and the outer casing, the inner casing being formed by winding and stretching bands or strings on the core, or by moulding. In a modification, an outer perforated shell encloses an inner core of elastic material, preferably made hollow.
