Title: A New or Improved Preparation of Orthochlorophenol.
Inventor: O'BRIEN JOHN OWDEN
Filed: 1899-04-12
Granted: 1899-06-24
Abstract: 7704. O'Brien, J. O., [Hazard-Flamand, M.]. April 12. o-Chlorophenol is prepared by the following operations :-First, p-phenol-sulphonic acid is produced by heating phenol with sulphuric acid to 100‹ or 110‹ C. for six to seven hours in vacuo. This product is mixed with hydrochloric acid and water, in a vessel which can be cooled by means of a double bottom, and potassium chlorate is gradually added, while care is taken to keep the temperature below 50‹ C. o-Chlorophenol-p-sulphonic acid is thus produced, and this compound is converted into o chlorophenol either by heating its monosodium salt with a trace of acid to about 200‹ C., whereby the sulphonic acid is decomposed and o-chlorophenol is distilled off ; or by diluting the o-chlorophenol-sulphonic acid with water and heating it in an enamelled digester for fifteen hours. The black oily product is separated and then purified by distillation alone, or in a current of steam.

Title: Improvements in and relating to Chemical Fire-extinguishing Apparatus.
Inventor: YOUNG WILLIAM LAURENCE
Filed: 1901-05-23
Granted: 1902-04-24
Abstract: 10,657. Young, W. L. May 23. Extincteurs; automatic appliances; alarms, fire.-Relates to an extincteur, which is automatically started by the heat of the fire. In case of fire, a fusible link t, Fig. 1, is severed, and this allows a spring piston inside the tube g to descend and fire a cartridge in the tube f. The cartridge may also be fired electrically, the electric circuit being closed by the fusion of an insulator. The bullet strikes the end of the rod d, which is thus forced downwards and breaks the acid bottle b. The pressure generated by the mixture of the acid and alkali forces the liquid up the pipe k, from which it is discharged by a rotating nozzle n. This nozzle, shown in plan in Fig. 6, is rotated by the action of a tangential jet h. On one arm of the nozzle, a subsidiary reaction nozzle q rotates and spreads the liquid in vertical planes. The terminals q, q<1>, Fig. 1, of a circuit containing an alarm and an indicator, are brought in contact when the link t is severed. By pushing down the telescopic tube l, a valve at the bottom of the pipe k is closed, and, when the automatic starting-device is removed, the extincteur can be worked by hand in the ordinary way.

Drying fabrics.-Cotton goods are sized or starched on one side and are fed through a drying- chamber in such a manner that the sized surface does not come into contact with itself or any foreign body, the drying being effected by hot air adapted to produce a uniform effect. The fabric j is fed from the roll a under the sizing-rolls b, b<1> and thence round a roller c, and to the drying- chamber as indicated by the arrow, a doctor b<11> serving to spread the dressing in a uniform layer. In the drying-chamber the fabric is formed into folds, as shown, the folds being formed and the fabric fed by hooks z<1> on an endless chain z. The hooks take up from an incline or shoot y rollers which abut against the fabric and thus fold it. The rollers carrying the fabric drop the chains Z to endless cords or ropes x which move on rollers x<111> and thus the folds are fed along. Oscillating plates p serve to keep the rollers apart and in position on the cords. When the folds reach the end of their travel, the rollers are received by hooks on endless chains from which they are allowed to fall down an incline, the fabric being then fed from the appa- ratus. A movable, transparent, partition may be used to protect the workmen from the heat. The drying-apparatus may be also used independently.

The holder is mounted upon a base-plate d, which carries pillars e forming guides for the upper plate f of the holder, and supporting a plate h. Springs g surrounding the pillars supply the necessary pressure for the holder. The retort is moved forwards over the lamp by a step-by-step motion, so that the whole of the contents are eventually decomposed. This is accomplished by the plate f, each time it rises, engaging with the end of a lever r<1> pivoted at r'. The other arm r of the lever carries a pawl q, which engages with a rack-bar i, from which the retort is carried. When the plate again falls, the lever returns to its original position under the influence of a spring, and the bar i with the retort is moved forwards one step. The generated oxygen passes through the flexible tubes m<1>, n to the bottom of the holder, the tube n entering through the base-plate d or through the top plate f. A non-return valve prevents the gas from passing backwards. A funnel t is inserted in the tubes, whereby water can be led to the bottom of the holder for the purpose of washing the gas. The gas leaves the holder by the tube o. A safetyvalve u is fixed on the cover f, and allows gas to escape when it rises sufficiently to engage with a stop v.
