Title: Improvements in the Decomposition of Alkaline Salts by Electrolysis and in Apparatus therefor
Inventor: GREENWOOD JAMES
Filed: 1900-12-08
Granted: 1901-10-12
Abstract: 22,406. Greenwood, J. Dec. 8. Chlorine and hydrogen, obtaining electrolytically from alkaline chlorides. The process is arranged in two stages :-(1) in which the alkaline chloride is broken up into chlorine and the metal, the latter being absorbed by the mercury; and (2) in which the amalgam is treated as the anode to form a weak lye solution. Fig. 1 shows two series of cells a, b, along the lower surface of which the mercury is caused to circulate by means of the pump i. The bottoms of the cells are formed of iron covered in strips with enamel, the spaces between the enamel being grooved or left plain. The cells are divided by slate or other insulating-partitions g which dip into recesses h. Alternate compartments contain carbon slabs m, threaded on rods, and resting on supports o forming connection with the lead q. The other compartments contain grids of iron, similarly supported, and arranged to act as cathodes for the decomposition of the amalgam. The current in these cells is reduced by a shunt. In a modifie d form, the trough a, forms the cell for the first stage, and the trough b forms the cell for the second stage. The trough in this case is divided into cells, and the lye solution circulates in the opposite direction to the mercury. The chloride and hydrogen are collected from their respective cells. The cells may have the walls hollow to allow cooling-liquids to circulate.

Title: New Process of Soldering with Oxy-hydrogen Gas.
Inventor: GARUTI POMPEO
Filed: 1901-07-13
Granted: 1902-01-16
Abstract: 14,306. Garuti, P., and Pompili, R.., [trading as Garuti & Pompili]. July 13. Soldering and brazing.-In oxyhydrogen gas blowpipes, in order to mix the gases without danger before they reach the flame, the gases are used under a pressure which will eject them with a velocity superior, or at least equal, to the velocity of the propagation of the flame to the mixture. This pressure should not be less than 30 centimetres of water and should be able to reach 60 to 80 centimetres for strong jets ; 4 parts of hydrogen are preferably used to 1 part of oxygen. In order to maintain an equal pressure upon the gases, the arrangement shown is employed. The movement of a needle 5 in an aperture in the neck of each reservoir regulates the outflow of the gas to the mixing-chamber 10 and jet 11. Each needle is suspended from the spring-controlled diaphragm 6, such that any variation in the pressure of the outflowing gas will cause a corresponding alteration in the outlet. The mixture is obtained in the suitable proportion by the adjustment of the micrometer screw-taps 9.

Granted: 1902-07-19
Abstract: 14,721. Ellis, W. T. July 19. Locks, key; escutcheons, keyhole.-The first part of the invention relates to a padlock. The bow H is connected at one end by a link to a pivoted disc B, and at the other end it has a slotted hole adapted to receive a pin P passing through a hole in the casing. The disc B is provided with indents x, y adapted to be engaged by a spring-controlled pawl F. When locked, the pawl engages the indent x, and the pin P engages the holes in the bow and casing. In unlocking, the pawl F is moved out of engagement with the disc, by means of a key E, and is afterwards released, the bow is then pulled out, thereby turning the disc until the pawl engages the indent y. In this position the slots in the hole in the bow and in the holes in the casing are brought into line so as to allow a projection on the pin P to pass. The pin can now be withdrawn, until it engages the slot in the front plate, and the bow H is free. The locking is performed by a reverse operation. The second part of the invention relates to a keyhole guard and a blocking-device for the mechanism, and is applicable to any lock. A keyhole cover A, provided with a long and a short recess, is adapted to slide on a dovetailed projection on the front plate of the lock. A spring-controlled sliding piece K, mounted on the back of the front plate, has a projecting part passing through the plate and, normally, engaging the short recess. A piece W, prevented from rotation by contact with a stop, forms a nut for the engagement of a screw R, passing through the front plate. This piece W may be moved by rotating the screw so as to bring it in position for locking some part of the lock mechanism, such as the pawl F. In operation, the cover A is raised to expose the keyhole. The key is inserted and turned to pass the end of a pivoted lever L. The key is then turned to depress the lever L, which engages the piece K and slides it forward into engagement with the long recess in the cover A. The cover is forced downwards, after the withdrawal of the key, and the head of the screw is exposed. The screw may now be operated to release the piece W from engagement with the lock mechanism. By reversing the operations, the mechanism may again be blocked.
