Title: Improvements in Sound Reproducers or Intensifiers applicable to Phonographs, Gramophones, Telephones and the like
Inventor: PARSONS CHARLES ALGERNON
Filed: 1903-05-08
Granted: 1904-08-08
Abstract: 10,468. Parsons, C. A. May 8. Phonographs &c. ; telephones; ; telephone systems.-A valve controlling the escape of compressed air is operated by the stylus of a phonograph, gramophone, or like instrument, or by the diaphragm of a telephone, so as to intensify the sound and act as a relay. Fig. 3 shows a section of one form of the arrangement as applied to a gramophone. The chamber g, supplied with compressed air, is packed on one side of the gauze screen g<1> with cottonwool to act as a filter. The valve seat l is in the form of a fine grating, and the valve cover m is a comb, or grating, with tapering teeth and made as small as possible to combine strength with lightness. The valve cover is situated on the side of less pressure, and is attached to a weigh-bar n, mounted on springs so that the oscillation of the style q moves the valve to and from its seat, the extent of opening being approximately proportional to the displacement. The position of the valve cover is adjusted by means of the spring arm w and thumb-screw z. The trumpet tube t is formed with an opening for the valve with as little clearance as possible. One or more sharp bends may be made in the tube, and the narrow end of the trumpet may be lined with velvet or other material to improve the tone. When applied to phonographs, the valve is placed horizontally and is worked through a link from a stylus lever pivoted on a weighted arm. A valve of a different type is shown in Figs. 10 and 11. The valve seat consists of the edges of a zig-zag 8 of sheet metal, one side of which is connected to the air-supply chamber 10 and the other to the trumpet 11. The valve cover consists of a pad 18, composed of alternate layers of goldbeaters' skin and silk, on a plate of mica 13, supported by about five arms 17, of the weigh-bar 14. The zig-zag is produced by covering the flat metal with paper, and, after bending the plate and paper, as required, the latter is dissolved away. The valve seat may also be formed by the edges of a number of flattened tubes, tapering from their bases, where they are soldered together, to half the width at the valve face.

Granted: 1904-07-21
Abstract: 5203. Auld, J. March 2. Reducing-valves; piston valves.-In the reducing- valve shown in Fig. 1, for use in maintaining a uniform speed in an engine, the valve is formed with two piston parts C, G connected by a neck F, and sliding in a lining B and in the upper part of the valve-casing A respectively, as shown. In operation, the steam entering at I flows round the passage S and through the port K into the cylindrical lining over the piston C, and thence out by the passage J. The space D below the piston C is open to the space above the piston by means of a passage E, so that steam enters this space and tends to raise the valve to close and throttle the port K, this tendency being counteracted by weights or by a spring N above the valve, adjusted by a screw Q to the pressure of steam required. An exhaust outlet R is arranged in the casing round the spring N. The valve may be screwed up against the flange L of the lining B, and thereby closed, by a screw passing through the lower cover-plate M. In a modification, the lining B is dispensed with.

Motor cycles ; driving - mechanism. -Relates to epicyclic change-speed gear for motor vehicles and cycles &c., in which an epicyclic train is interposed between a friction clutch and an ordinary gear box. Fig. 2 shows an arrangement suitable for tri-cars and motor cycles, in which the engine-driven sprocket-wheel W is attached to the annular wheel P', the pinions Q, clutch cup C<1>, and driving sprocket-wheel X being fixed to the sleeve Q<1>. To change from the locked position for high gear shown, the cone G<1> is slid from the cup along the sleeve G<2> fixed to the axle Y, and is locked against a friction surface (not shown). The planet-pinions Q then operate, giving a low gear. Fig. 3 shows an adaptation of the gear to a cycle hub. The belt or chain sprocket W<1> is attached to the annular wheel P' and the road wheel, and the disc Q<1> carries the pinions Q and clutch cup Z. The clutch disc Z' has projections Z', which pass through the slotted sleeve N<2> of the sun-wheel N', thereby causing the two to rotate together, whilst allowing disengagement of the clutch. Disengagement may be effected by a band brake having a bevelled surface, which slides the cone Z' laterally and then locks it, so as to bring the pinions into action for low gear. The Provisional Specification describes further modifications in the arrangements of the parts of the epicyclic gear.

Filed: 1905-06-20
Granted: 1906-04-05
Abstract: 12,756. Cooper, E. H., (executor of Newton, H. E.), [Farbenfabriken vorm. F. Bayer & Co.]. June 20. Dyes, artificial; urethanes; amines; nitramines.- Urethanes of aminoanthraquinones are successively nitrated to form nitrourethanes, saponified to form nitramines, and reduced to form diamines. The o-diaminoanthraquinones are then condensed with #-diketones such as phenanthrene quinone, to form dyes which are probably azines. The urethanes may be produced by the action of chlorcarbonic ether on aminoanthraquinones, or by treating with alcohol the carbamic chlorides produced by the action of phosgene on aminoanthraquinones. In examples, the urethanes of alpha- and #-monaminoanthraquinone are nitrated, the following products being obtained : the urethanes of 1 : 2-, 2 : 1-, 3 : 2-, and 4 : 1-nitroaminoanthraquinones. By saponifying with sulphuric acid, the corresponding nitramines are obtained. Reducing-agents such as sodium sulphide, sodium sulphydrate, zinc dust, or stannous chloride and caustic soda, convert the nitro groups into amino groups. The o-diamines when condensed with #-diketones yield substantive dyes which are probably azines. The dyes yield vats with hydrosulphites and caustic alkalies. In examples, 1 : 2, and 2 : 3-diaminoanthraquinones are condensed in presence of glacial acetic acid with #-anthraquinone, #-naphthoquinone, phenanthrenequinone, or with the oxidation product obtained from alizarin blue by oxidation with nitric acid. The products dye cotton blue, green, yellow, &c. shades.

Title: Improvements in Electric Motor Control Systems.
Inventor: MAGNUSON AXEL
Filed: 1905-09-07
Granted: 1906-09-06
Abstract: 18,125. Magnuson, A. Sept. 7. Motors, controlling.-Relates to motor control systems in which resistances or regulating - transformers &c. are gradually and automatically cut out of the motor circuit by electro - magnetic switches energized by current from a small dynamo, which is mechanically connected to the motor ; the main circuit of the motor is closed by electro-magnetic switches under the control of a starting and reversing switch in an auxiliary circuit. The generator 20, Fig. 3, may be connected to the motor 10 by belt gearing as shown, or the connexion between the two machines may be made directly by a suitable clutch. In the application of the system to a polyphase motor, shown in Fig. 4, the switch 46 or 66 is closed by the electro-magnet 42 or 62, and resistance 73 is gradually cut out by switches 88, 98. 108 operated by electro-magnets 80, 90, 100. When the main switch 31 is closed and the starting- switch 51 moved to the left, the circuit of the electro-magnet 42 is closed through the contacts 53, 54, contact 57, and conductor 43. The movement of an armature causes the contacts 46, 47 to engage the contacts 46<1>, 47<1> and so complete the circuit of the motor 10, the terminals 16, 17 being connected to the mains 32, 34 respectively. The direct current from the generator 20 energizes the magnet 42<1>, the circuit of which is completed through the contacts 56, 57 of the starting-switch 51, and the armature being pulled to the left holds the contacts 46, 47 against the contacts 46', 47<1> and prevents chattering. To reverse the motor, the starting-switch 51 is moved to the right, when the electro-magnets 62, 62<1> are energized and the terminals 16, 17 thereby connected to the mains 24, 32 respectively. The resistance 73 is gradually cut out of circuit, as the motor speeds up, by the successive closing of the switches 88, 98, 108, the inner part of the resistance being first shortcircuited by the switch 88, and finally the whole resistance short-circuited by the switch 108. To ensure the successive operation of the switches, the electro-magnets 80, 90, 100 are adjusted by springs or weights or by setting the cores at different positions in the windings. In order that the current generated hy the dynamo 20 may be unidirectional, the brushes 26, 27, Fig. 2, are mounted on the yoke 26<A>, which is provided with antifriction rollers and moves through 180 degrees when the direction of rotation of the generator is reversed, the rotation of the yoke 26<A> being limited by stops 27<B>, 27<c>, which engage with an arm 27<A> on the yoke.
