Title: Process for the Manufacture of Dry Sulphates of the Alkali Metals and the Products thereof.
Inventor: TRIVICK SIDNEY
Filed: 1903-04-18
Granted: 1904-04-14
Abstract: 8819. Trivick, S. April 18. Chemical furnaces. - Potassium, sodium, and ammonium tetrasulphates, which are dry portable salts of the composition M2O (SO3)9 with not more than three molecules of water of crystallization, are produced by heating the corresponding proportions of concentrated or fuming sulphuric acid and an alkali salt to a temperature not exceeding 250‹ C., then granulating the mass by stirring it while cooling, and finally exposing it to a current of warm dry air. Sodium chloride and potassium sulphate in the form of nitre-cake are mentioned as suitable alkali salts. The apparatus employed comprises a pan a mounted by its flange upon the external walls of an annular flue b and in part supported by the conical inner walls thereof. The flue is heated by the products of combustion from a grate c. The pan is charged with sulphuric acid, and the alkali salt is allowed to fall in gradually from a sloping hinged door h, fitted with a counterweight k, by slightly opening the door at intervals. When sodium chloride is used, the hydrochloric acid liberated escapes by a pipe l to a condenser. When the reaction is completed, a wheeled vessel is run in through the doorway m, and the plug n is unscrewed for emptying the van.

Title: Improvements in the Manufacture and Production of Colouring Matters of the Acridine Series.
Inventor: JOHNSON JAMES YATE
Filed: 1903-08-17
Granted: 1904-06-09
Abstract: 17,768. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Aug. 17. Dyes, artificial.-Colouring-matters of the acridine series are obtained by heating with glycerine acridine-yellow, benzoflavine, m-amidobenzoflavine, or the hydrochlorides of the leuco compounds of such colouring-matters. The proportions of the ingredients, and the time and temperature of the reaction may vary, the usual temperature, however, being about 165‹ to 180‹ C. After the reaction, the melt is dissolved in water, containing in some cases a little hydrochloric acid, and the colouring-matter thrown out by common salt. After removing the mother liquor, a small amount of hydrochloric acid is added, and the dye dried at the temperature of the boiling water-bath. The dye obtained from acridine-yellow is a redbrown powder, is easily soluble even in cold water, dissolves to brown solution with a green fluorescence in concentrated sulphuric acid, and dyes cotton mordanted with tannin, and also leather, orange shades. The dye obtained from benzoflavine and glycerine forms an orangeyellow powder, less soluble than the last dye ; it dissolves to a bright yellow solution with a green fluorescence in concentrated sulphuric acid, and dyes tannin-mordanted cotton and leather vivid orange-yellow shades. The dye obtained from m-amidobenzoflavine is easily soluble, and dyes tannin-mordanted cotton orange-yellow. The products obtained from the hydrochlorides of the leuco compounds and glycerine are identical with those above mentioned.

Title: Improvements in Milking Apparatus
Inventor: LJUNGSTROEM FREDRIK
Filed: 1903-09-11
Granted: 1904-08-11
Abstract: 19,616. Ljungstr÷m, F. Sept. 11 Cow-milkers.-In milking-apparatus, each teat is alternately compressed and distended by a number of pistons or cylinders operated in order, from the top downwards, by the energy of a liquid moving in a closed space. Each milker consists of a celluloid or other casing k, into which the teat is inserted, and a number of cylinders g, g<1>, g<2> in which pistons e, e', e<2> are displaced by the movement of the liquid in a pipe d. The liquid may be moved by means of a piston exerting forcing and suction action alternately in a pump cylinder in communication with the pipe d. In the form shown, the first cylinder g is in direct communication with the main pipe d, the second g' with the conduit h<1> leading from the pipe h and the third g' with a conduit h<2> from the pipe h<1>. Nozzles i, i<1> may be provided to increase the injector action, and so ensure movement of the pistons in the proper order. In a modification, two pistons press an elastic bar against the teat so that the pressure gradually extends from the top downwards. In another form, the cylinders move upon fixed hollow pistons and are provided with pads to press against the teats.
Patent GB-190321071-A (GB)
Title: Work Clamps for Buttonhole Sewing Machines
Inventor: FAIRWEATHER WALLACE
Filed: 1903-10-01
Granted: 1904-07-14
Abstract: 21,071. Fairweather, W., [Singer Manufacturing Co.]. Oct. 1. Buttonhole-sewing machines.-A work-clamp for buttonhole-sewing machines consists of two feet or members 24, which are pressed down on the work and are then moved apart, to spread the buttonhole slit to facilitate the stitching, or, when the buttonhole is not previously cut, to part the material under a transverse tension to facilitate the stitching and the subsequent cutting operation. The feet 24 are carried by arms 22 pivoted at 23 on an upper plate 21, which is pivoted on a fulcrum-block 18 on the base-plate 12. The arms 22 are connected by a spring 26 tending to draw them together, their inward movement being limited by a stop 31, which is adjustable to suit different widths of stitching. The spreading movement of the feet is effected by the cam 29, on the rocker 27, acting on abutment plates or blocks 30, which are adjustably mounted on the arms 22, to permit variation for different widths of seam, the adjustment of the blocks 30 compensating for the adjustment of the stop 31, so that the spreading movement remains the same. The feet 24 are pressed down on the work by the spring 35, and are raised by a treadle connected through the hook 38, Fig. 1, to the rocking lever 36 on the outer end of the plate 21. The lever 36 is connected by the pitman 40 to the arm 28 of the rocker 27, and by these means actuates the cam 29 to spread the feet 24. The lever 36 is normally held in the position shown in Fig. 1, by the spring 37, which is weaker than the spring 35 but much stronger than the spring 26, the movement of the lever being limited by the adjustable stop 39. When the treadle is depressed to raise the feet 24 for the insertion of the work, the lever 36 is tilted, against the action of the spring 37, and moves the cam 29 to permit the feet 24 to be drawn towards each other by the spring 26. When the treadle is released, the feet 24 are first forced down on the work by the spring 25 after which the spring 37, overcoming the spring 26, returns the lever 36 to its normal position, and so actuates the cam 29 to impart the spreading movement to the feet 24. The feeding and shifting movements of the clamp may be imparted by the means described in Specification No. 20,358, A.D. 1902.

Title: Improvements in and relating to Rock Drills or the like.
Inventor: WALTON CECIL
Filed: 1904-01-19
Granted: 1904-11-17
Abstract: 1340. Walton, C., and Rayner, G. H. Jan. 19. Rock drills, percussive. In a rock drill worked by compressed air, the distributing - valve is air driven and the air ports are so arranged as to prevent the valve from chattering. Compressed air enters the valve-chest f<1> through an inlet a and ports b, c, d, e, and at the begining of the outward stroke of the piston k the ports b, d, e are cut off from communication with the cylinder i by means of the distributing-valve f, the only communication being through the port c round the valve f and through a port g. The forward end of the cylinder i is open to exhaust through a port h and the air in the valve-chest f<1> supplied through the port b exerts pressure against the back of the valve f, and holds it in position, the forward end of the valvechest f<1> being in communication with the exhaust through a passage l which leads to the interior of the cylinder and is in communication with the exhaust. During its forward stroke the piston k, which is formed with an annular groove k<1> round its middle, covers the passage l and uncovers a similar passage m, thereby throwing over the valve f in position for the reverse stroke of the piston. Instead of employing the ports b, e, passages n, o may be formed through the valve itself.

Patent GB-190412365-A (GB)
Title: Improvements relating to Telphers.
Filed: 1904-05-31
Granted: 1905-05-31
Abstract: 12,365. Siemens Bros. & Co., [Clift A. S.]. May 31. Electric railways.-Relates to telpher lines in which the system is divided into insulated portions from which the telpher, as soon as it passes; cuts off current from the portion it leaves and at the same time supplies current to the section immediately preceding the one deprived of current. The telpher line a is carried by hangers b, supported on springs d. The trolley wire c is divided into sections operated by the automatic switches e, each consisting of four contacts and two fingers j, k. The normal position of the switch is against the contacts f, g, that shown in Fig. 1 being in the section through which the telpher has just passed. The sections are fed from a cable, as shown in Fig. 2. As the telpher s passes over the hanger b, the spring p is extended until it overcomes the spring m which keeps the switch against the upper contacts, and draws the rod l down until the lower contacts are bridged. This retracts the stop n of the section to the rear of that from which the telpher has just passed, and allows the corresponding rod l to rise until the upper contacts are bridged, thus supplying that section with current. In this way, the section immediately behind the telpher is without current, and is supplied only when the telpher has passed out of the section in advance. Any number of sections may be arranged to be dead by carrying the catch-solenoid operated from the lower contacts further back along the line.

In the apparatus shown in Fig. 6, two cranked levers n, n<3>, with slots cut in each so as to meet at right-angles at the point o, are mounted on pivots o which are attached to the carrier for the lens y, which in this case is fixed to the baseboard z. Two pins q on the negative carrier b move in the slots in the arm of the lever n<3>. Two other pinap fixed to the positive carrier a move in slots n<2> in the arm of the lever n.. Both carriers slide along the baseboard z, and the ratio of enlargement or reduction may be varied, and the positive still kept in focus, by moving one of the movable carriers, the other being moved by the action of the cranked levers. The position of the pins q, p may be varied with respect to their carriers to allow the use of lenses of different equivalent focus. Either of the three carriers may be fixed to the base, and the levers may be attached on any side of the camera. Only one cranked lever may be used if desired. The cranked levers may be replaced by straight levers pivoted on the lens carrier and controlling the relative position of the parts by means of sleeves sliding on a screwed pinion and carrying pins which move in slots in the lever. The pin-and-slot arrangements may be replaced by any equivalent.
