Patent GB-190602902-A (GB)
Title: Improvements in and connected with the Nitration of Cellulose.
Inventor: BRIAILLES GASTON CHANDON DE
Filed: 1906-02-06
Granted: 1907-01-03
Abstract: 2902. Chandon de Briailles, Count G Feb. 6. Nitrocellulose is produced by electrolyzing a mixture of strong sulphuric acid and ordinary nitric acid in the presence of cellulose. The acids are stated to be thus electrolytically concentrated. The glass vessel, Fig. 1, has a glass valve 9, a porcelain shelf 12 with cellulose on top of it, platinum or gilded platinum electrodes 16, 17, a thermometer 14, and an hydrometer in a vertical, perforated glass cylinder. The anode 16 is close to the porcelain shelf. The immersed cellulose is nitrated in about three or four hours, but the temperature must lie between 30‹ and 40‹ C. The nitrous acid produced at the cathode assists the nitration of the cellulose. It is stated that the same mixture of acids can be used for an indefinite length of time, save that a part of the nitric acid goes to form nitrocellulose. Washing is effected by removing the acid by an acid suction pump, and, further, the cellulose can be squeezed by means of the porcelain piston 18, 19 passing through a flexible india-rubber stopper. Water is then fed into the apparatus through the tube 8, and then withdrawn. This is repeated until the nitrocellulose no longer evolves vapour. The receptacle is opened and the nitrocellulose further washed in the air. Before nitration of the next lot of cellulose, the moisture left in the vessel is carefully pumped out.

Patent GB-190614122-A (GB)
Title: An Improved Method in the Manufacture of Saccharin.
Inventor: LYNDE WILLIAM ALFRED
Filed: 1906-06-20
Granted: 1907-02-07
Abstract: 14,122. Lynde, W. A. June 20. Saccharin.-In the production of saccharin from toluene without the intermediate production of p-toluene sulphochloride the methyl group is oxidized to the carboxyl group before the sulpho- or sulphamide group is introduced. For example, toluene is oxidized at a low temperature with a mixture of sulphuric and nitric acids, and the o- and p-nitrotoluenes are separated by fractional distillation or other known means. The o-nitrotoluene is then oxidized, preferably with potassium permanganate, to o-nitrobenzoic acid. This is then reduced to o-aminobenzoic acid, which is diazotized and treated with cuprous chloride, to convert it into o-chlorbenzoic acid, which is then treated with sodium sulphite with the formation of sodium o-sulphobenzoic acid. The sodium salt is transformed into the bichloride by means of phosphorus trichloride and chlorine. The bichloride is then treated with ammonium carbonate, and the saccharin precipitated by acid and filtered. In another example, the o-nitrotoluene is reduced to o-toluidine, which, by being diazotized and treated as described above, is converted into o-chlortoluene. This latter is then oxidized to o-chlorbenzoic acid, and the sulpho group is then introduced and further operations carried out as described in the first example.

Title: Improvements in Sound Producing Instruments such as Gramophones and the like.
Inventor: DENNISON WILBURN NORRIS
Filed: 1906-11-15
Granted: 1907-08-08
Abstract: 25,875. Dennison, W. N. March 8, [date applied for under Patents Act, 1901]. Phonographs &c. -In a gramophone or like machine in which undulations corresponding to sound waves are impressed upon a moving fluid current by vibrating a valve connected to a stylus, the sound - box is attached to a soundamplifying horn which forms a swinging arm, and the moving member of the valve is cushioned by the fluid which passes therethrough. The inner end of the swinging arm 24 is provided with a T-shaped connexion 27, to the outer end of which are secured U-shaped tubes 28. 29 having their other ends attached to the sound-box. These tubes are rotatably mounted on the T-shaped connexion, so that the sound-box can oscillate freely about an horizontal axis. A fluid-supply pipe 31 is attached to the swinging arm 24, and a partition 32 divides the connexion 27 into two compartments. The sound-box 30 comprises a casing 33, within which is situated a fluid deflector and distributor 35 of conical form, the diameter of which is slightly less than the diameter of the casing. This deflector is mounted upon a stud 36 supported by radial arms which are carried by a ring 38. A secong ring 39 fits inside the ring 38 and holds in place a filtering-diaphragm 40 of woven silk fabric. A cap 42 is screwed over the open end of the casing 33, and between this and the casing is clamped the stationary member of the valve 44 having a positioning-pin 45 which enters an opening 47 in the cover. The member 44 is provided with a series of parallel slits, and a stylus bar 50 passes through a radial opening 49 in the cover 42, a lug at the inner end of which is secured by a screw 56 to a movable plate 52 having openings similar to, but which do not register with, those in the member 44. A tension spring 57 passes through the stylus bar 50 and is attached by screws to the member 44. A screw 60 attached to the stationary valve plate prevents lateral displacement of the movable member, and a rubber washer 61 may be provided between the screw head and the outside of the moving member. When air or other suitable fluid is conducted through the supply pipe to the sound-box, it is deflected to the outer edges of the screen 40 and thus distributed more uniformly. The member 44 is preferably provided with a depression in which the movable member 52 is located, and the air trapped between the sound-box and the movable member forms a cushion for the latter, which the washer 61 tends to keep in position. By the oscillations of the stylus, the movable member is slightly raised, varying the volume of air passing through the valve, and setting up undulation corresponding to sound waves. The movable member of the valve is preferable flexible, and the apertures in the moving and stationary members of the valve may be annular. The screw 60 and washer 61 may be dispensed with, permitting the valve to vibrate freely.

Granted: 1908-11-30
Abstract: 26,345. Scott, H. S., and Tyzack, H. F. Nov. 28. Working - valves.- Valves of the piston type, fitted with balance pistons constructed so that when the valve is closed there will be a pressure tending to keep it closed, are constructed and adapted for controlling hydraulic machines and apparatus ; Fig. 1 shows one form of the valve. The casing a is provided with a port c leading to the machine, an inlet port b, and an exhaust port d. A piston g slides in the chamber e leading from the port c to the port d, and is connected at its underside with the balance piston j of equal area. The conical seating formed on the said underside of the piston g seats on the wall of the restricted passage n leading to the inlet port, so that when the latter is closed the total effective pressure tends to keep the valve g on its seat. The other end of valve 9 may close against a seat s during admission. In the modification shown in Fig. 2, the spindle h passes out through the inlet end of the casing, and the valve is provided with an enlargement t adapted to pass into the reduced passage n, and also with an extension v adapted to pass into the exhaust chamber q. The enlargements t, v are so arranged that when the valve g moves to close the passages f to the port c, the enlargement t passes into the reduced passage n and the enlargement v passes out of the exhaust chamber q, so that the pressure on the inlet side of the valve is reduced, and the valve is automatically closed on its seat.
Patent GB-190727260-A (GB)
Title: A New or Improved Alternating Current Machine.
Inventor: GOLDSCHMIDT RUDOLF
Filed: 1907-12-10
Granted: 1908-07-23
Abstract: 27,260. Goldschmidt, R. Dec. 10. Field magnets; rotary converters and transformers.-An alternator, synchronous motor, or frequency-converter for single or polyphase current has a single-pbrase rotor winding shortcircuited upon itself, the stator carrying both the armature windings and exciting-coils. The rotor B carries the single-phase winding W<2>, which may be a squirrel-cage winding, or a winding shortcircuited through brushes bearing upon slip-rings. The stator A carries the exciting-coils W<1> and the armature-winding proper W<3>. When employed to convert direct current to alternating current, the field winding W<1> is excited by a direct-current taken from the exciter or from a battery. If the rotor revolves in this field, the currents set up in it produce a second field which revolves at double the speed of the rotor. This field sets up an electromotive force in the winding W<3>. The windings W<1>, W<3> may be concentrically arranged or may be angularly displaced, and they may occupy the same or different slots. The winding W<1> may form part of the winding W<3>, and if the latter winding is a polyphase one, one or two phases may have a larger section than the others so that they can take also the exciting-current, one coil sufficing for both windings. Choking-coils may be arranged in series with the winding W<1> to prevent alternating currents from circulating in it. Alternating current may be supplied to the winding W<1>; the current generated in the winding W<3> will then have a different frequency, the machine serving as a frequency-converter. To cause the machine to operate as a synchronous motor, alternating current is fed into the winding W<3>, and the winding W<1> is excited by direct current as before. Such a motor may be made self-starting as an asynchronous machine by means of current induced in the rotor winding. The rotor winding may be connected polyphase at starting and changed over to form a short-circuited single-phase winding for normal synchronous working. The functions of stator and rotor may be interchanged, the part described as the rotor being stationary, and vice versa.
