Abstract: 10,490. Davies, J., and Ryan, T. P. May 21. Indicators, station &c.-Relates to street or station indicators for use in public conveyances. The names of the streets or stations are printed on the curtain 10, which is drawn from the spring roller 6 on to the roller 4, or vice versÔ, according to the direction in which the vehicle is travelling. The curtain passes round guide-rollers 11, 12, and the names are exhibited in succession through the aperture 13 in the casing. The roller 4 is rotated by the pawl 26 and ratchet-wheel 14, to draw up the curtain from the roller 6. In the opposite direction of travel, the roller 4 is rotated in the reverse direction by the pawl 28<1> and ratchetwheel 16, and the curtain is rewound on the spring roller 6. Both pawls are carried by the armature 25 of the operating-electromagnet 24, and the ratchet-wheels are carried by a sleeve feathered on the shaft 3 of the roller 4. The sleeve is engaged by a forked lever 19, which has an arm 21 in the path of two clips 22 mounted near the ends of the curtain 10. On the operation of the lever 19 by one of the clips, the ratchet-wheels are shifted laterally with respect to their pawls, to reverse the gearing. A bell is rung at each operation of the indicator, the bell hammers being actuated by a tappet-wheel on the shaft 3. A brake shoe 31 on the armature 25 limits the movements of the indicator.

Title: Improved Means for Producing Chlorates or Perchlorates of the Alkali Metals.
Inventor: THRELFALL RICHARD
Filed: 1902-02-05
Granted: 1903-01-22
Abstract: 2987. Threlfall, R., and Wilson, G. E. Feb. 5. Alkaline chlorates and perchlorates; salt, cominon. -A solution of sodium or other alkali metal chloride, to which sodium or potassium chromate or bichromate may be added, is electrolysed between an anode d and a cathode e in an earthenware or other cell b. A small fraction of the current passes from the anode d to an auxiliary cathode f, placed in a part of the electrolyte separated from the bulk in the cell b by a porous partition. The auxiliary cathode may be connected through a resistance g and a switch. A small excess of chlorine is thus produced at the anode, tending to free hydrochlorous acid in the bulk of the electrolyte, by which rapid formation of chlorate is facilitated. The solution in the auxiliary vessel a may be circulated ; the alkaline solution produced there may be carbonated and then boiled with the crude chloride solution, to free this from iron, calcium, or magnesium salts, for use as the electrolyte. The apparatus may be arranged in various ways. Several anodes and cathodes may be used in the main cell b. They may be platinum or platinum-iridium sheets, but the anodes may be carbon, and the auxiliary cathode may be iron. The porous partition may be interposed between the cell b and the auxiliary vessel a, as shown, or may be a pot dipping in the solution in the cell b. Or the porous partition may divide a detached auxiliary vessel into two compartments, one containing the auxiliary cathode f; the other compartment contains an auxiliary anode, and is connected by circulating-pipes with the main electrolytic cell and with a cooling- vessel. The auxiliary electrodes may be supplied with current from an independent source. The Provisional Specification states that the auxiliary vessel in the last modification may be completely disconnected from the main cell, the solutions being transferred periodically ; and that subsidiary electrodes may be used in the main cell, and the auxiliary cathode and anode may be connected to any of them having suitable potentials.

Granted: 1903-10-08
Abstract: 23,797. Fell, J. M. Oct. 31. Telephone calls; telephone systems; telegraphs.- Relates to systems for the simultaneous transmission of telegraphic or telephonic signals over the same line wires, and to apparatus for receiving telephone call signals of a character which does not interfere with the working of the telegraph system. The telephone calling- signal consists of an alternating current at a frequency of about 300 periods per second and a pressure of about 20 volts, produced by a magneto-electric generator or by a vibrating contact-breaker and induction coil &c. Fig. 2 shows a relay device which responds to the calling-current, and breaks the normally-closed local circuit of an annunciator or other signalling instrument B, Fig. 3. The relay comprises a permanent horseshoe magnet M with pole-pieces which carry the coils C. An insulating-block S. adjustable by means of a lever K and screw I, supports the springs E, N which normally make contact at s, s', thus closing the local signalling-circuit. The spring E carries an armature D, which is set in vibration by the alternating calling-current. A nodal point is formed at R, and the vibration of the point s relatively to the more slowly vibrating spring N practically breaks the local circuit and actuates the signalling - instrument. An alternating-current generator G and signalling-key c are shown in Fig. 3. Fig. 4 shows the complete system of simultaneous telegraphy and telephony. The telephone circuit comprises the conductors V, W, each of which serves independently for a telegraph circuit with earth return. The telegraph instruments r, keys n, and batteries h are inserted in tho earthed conductors 8, 9, and 10, 12, impedance coils f being placed in these conductors to prevent the passage of the telephone currents. Branches to earth contain condensers i. Condensers x are placed in the line wires, and bridges d, with ground connections, cross-connect them. The switch X enables either the telephone T or the key c to be put to line. The key c normally puts the relay A in circuit, but connects up the generator G when required. A condenser x<2> shunts the generator.

Title: Improvements in the Aeration Of Liquids.
Inventor: WILBY RICHARD
Filed: 1902-12-16
Granted: 1903-02-05
Abstract: 27,673. Wilby, R. Dec. 16. AÙrating liquids. -The aÙration is automatically stopped or started as required by placing in the carbonic - acid generator A, Fig. 1, an inverted bottle B containing air. As long as the pressure of the gas in the vessel containing the aÙrated liquid is of the required amount, it acts to depress the acid in the generator A and keep it below the level of the carbonate K which rests on a metal network D<2>; at the same time the air in the bottle B is compressed. When the pressure of the gas falls below the required amount, the compressed air in the bottle B forces the acid out of the bottle, thereby causing it to rise in the generator and attack the carbonate. The supply of water to the aÙrating-vessel 1, Fig. 3, is automatically regulated by mounting the vessel on a platform 2 which is supported at one end by a spring 6 and is provided with rack teeth 11, which, as the platform rises and falls owing to a decrease or increase in the quantity of water in the vessel 1, act upon a pinion 9 to open or close the water cock.

Title: Improvements in or relating to Apparatus for Viewing or Projecting Stereoscopic and other Pictures.
Inventor: BOULT ALFRED JULIUS
Filed: 1903-05-30
Granted: 1904-04-14
Abstract: 12,373. Boult, A. J., [Jehn, E.]. May 30. Magic - lantern apparatus; stereoscopes.-Fig. 1 is a front elevation and Fig. 2 a sectional elevation of a stereoscope with slide-changing mechanism which may also be used for optical projection apparatus. The slides are stored by being slipped into radial grooves formed in the ends of a reel-like drum 6. Each slide, as it reaches the top, registers with a vertical groove 15 in which slides a frame 20 connected by a rod 19 to a crank 17 rotated manually by a knob 18. As the frame 20 is lowered, a pendent spring 21 with a hook 22 passes behind and below a slide, which, by the continued motion of the crank 17, is brought into position in front of the eyepieces 16, the motion of the crank being arrested by the engagement of a book 28 with a pin 27. This hook 28 is pivoted to a plate 29, which is raised by a handle 30 to release the pin 27. When this release has been effected, the further motion of the crank 17 raises the frame 20, thus causing a cross-bar 24 to strike against an abutting piece 25, by which means the cross-bar 24 is forced back to disengage the hook 22 and allow the slide to fall again. The pin 27 then strikes against a pivoted lever 34, which operates a pawl 36 to drive the drum 6 forward, a pocket at a time. The sides are illuminated by a mirror 42 through a window 43.
