Title: Improvements in and relating to Jet Condensers.
Inventor: BERTRAM DAVID NOBLE
Filed: 1903-09-11
Granted: 1904-07-28
Abstract: 19,576. Bertram, D. N., and Weyman, J. E. Sept. 11. Condensers.-In a jet condenser, the cooling water enters a chamber b, Fig. 1, and, passing up through a pipe d closed at the top by a cover e, issues through orifices g in ridges formed at the head of the pipe. The orifices g are controlled by a hood h, which is raised and lowered by a spindle and hand-wheel. The exhaust steam is admitted to the casing a at a short distance from the bottom, or through the hood a<1>, and the water is withdrawn through an orifice a<x>. Ridges u may be formed on the hood h to throw off moisture. Additional water may be injected, e.g., at starting, through orifices q controlled by a piston valve s mounted on a spindle r, the lower end of which is screwed, and passes through a bevel-wheel r<2> forming a nut. When the wheel r<2> is rotated by a bevel-wheel on a hand-wheel shaft r<1>, the valve s is raised or lowered. The dry air pump is connected by a pipe m to an annular pipe l surrounding the pipe d, and having nozzles projecting into the space below the hood h. The pipe d may have external flanges which may have gaps at intervals to permit the upward passage of air, or the pipe may be corrugated. In a modified form of apparatus, the pipe d is enclosed in a casing or sleeve forming an air space which communicates with the dry air pump. The sleeve is perforated and has external flanges. The pipe d may be divided into two parts by a diaphragm in the middle. The exhaust steam is admitted to the lower part, and water is admitted to the upper part. The condensing- water may be admitted to an inverted cone z on the hood h as shown in Fig. 5. The water flows down over flanges z<x>, and meets steam issuing through orifices z<xx>.

Title: Improvements in the Manufacture and Production of Derivatives of Pyrimidine.
Inventor: NEWTON HENRY EDWARD
Filed: 1903-10-10
Granted: 1903-12-10
Abstract: 21,833. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. Oct. 10. Di-imino-dialkyl-ozypyrimidines; dialkyl-barbituric acids.-Dialkylated di-imino-oxypyrimidines of the general formula :- when R#an alkyl radicle, are prepared from dialkylated cyano-acetic esters, and from the former are obtained dialkyl barbituric acids of the general formula :- In the case of 2 : 4-di-imino-6-dietbyl-6-oxypyrimidine, which melts at 295‹ C., an alcoholic solution of guanidine hydrochloride is added to a solution of sodium, or other alkali metal, in alcohol, the precipitated metallic chloride is filtered off, and sufficient diethyl cyano-acetic ethylester is added to the solution, the whole being heated about six hours on the water-bath. The alcohol is then distilled off and the new body precipitated from an aqueous solution of the syrupy residue by neutralization with hydrochloric acid. It is difficultly soluble in cold water, ammonia, dilute sodium carbonate solution and the usual organic solvents, and is soluble in boiling water and dilute caustic soda lye. Strong acids form good crystal lizing salts. The oxypyrimidine derivative is saponified with, for example, sulphuric acid. The mixture is boiled for about five hours with the use of a reflux condenser. Recrystallization from water gives pure dialkyl barbituric acid, in this case the diethyl derivative.

Title: Improvements in and relating to Air Brake Systems and Valves therefor.
Filed: 1903-12-03
Granted: 1904-10-06
Abstract: 26,463. British Thomson-Houston Co., [General Electric Co.]. Dec. 3. Brakes.-Relates to automatic air brake systems, and more particularly to the triple valve, and means for supplying the auxiliary reservoir from the train-pipe. The valve casing is divided by a diaphragm 11, and the spindle 10 carries four pistons, one of which, 12, is slightly larger than the others. The train-pipe 3 is connected to the valve and to the auxiliary reservoir, as shown, 5 denoting a non-return valve. A supplementary chamber 6, also connected by a non-return valve 8 to the reservoir, serves to render approximately constant the pressure in the corresponding chamber of the valve to which it is connected. Ports 18, 21, and 22 vent to the atmosphere. The normal release position under pressure is shown in Fig. 3 ; the pressure in the larger piston 12 overcoming that of the supplementary chamber. On a decrease of train-pipe pressure, the piston is moved to the position shown in Fig. 1, admitting reservoir air to the brake cylinder until the brake-cylinder pressure, together with the train-pipe pressure, overcomes the normal pressure in the supplementary chamber. The piston is thus placed in the lap position, shown in Fig. 2. The process may be repeated to increase the brake pressure. Release is effected by establishing the normal train-pipe pressure. The difference between the areas of the piston 12 and the others enables a small change in train-pipe pressure to effect a large change in brake-cylinder pressure.

Title: Improvements in Electric Arc Lighting.
Inventor: HEANY JOHN ALLEN
Filed: 1904-05-31
Granted: 1904-07-07
Abstract: 12,345. Heany, J. A. May 31. Drawings to Specification. Arc lamps.-Normally non-arcing electrodes are heated either by a bunsen burner or a spirit lamp, or by the preliminary passage of a small current, to allow the formation of an arc with a low pressure and current. Spherical or pencil-shaped electrodes of metallic oxides or salts of metals, such as cerium, thorium, calcium, magnesium, yttrium, and the like, are pressed into shape either alone or by using a binding-agent, such as a borate, carbonate, phosphate, or sulphate, or boric acid. The preliminary passage of the small current is effected by incorporating particles of conducting-material, such as platinum, gold, iridium, and the like, to produce a high resistance to be heated by the passage of this small current. A thermal or other equivalent device is introduced into the circuit to regulate the length of the arc, and a carbon resistance serves to regulate the current.

Title: Improvements in Rectifying Alternating Electric Currents
Inventor: CAROLAN EDGAR ALFRED
Filed: 1904-09-21
Granted: 1905-07-27
Abstract: 20,381. Carolan, E. A., [General Electric Co.]. Sept. 21. Vacuum tubes.-Conductive vapour is generated between the cathode and an auxiliary electrode, and the main electrodes are then subjected to an alternating electromotive-force, sufficient to produce a current; the anode may have a cooling-jacket, and the condensing-chamber is above the cathode. In one form, Fig. 1, the exhausted receptacle has three mercury electrodes 2, 3, 4 and a condensing- chamber 5. An alternating current is supplied from the secondary winding 8 of a transformer to the electrodes 2, 3. A battery 10 or other source is connected to the electrodes 3, 4 for starting, the negative end being connected to the electrode 3. On closing the switch 11 and tilting the apparatus an arc is started between the electrodes 3, 4, thus producing a supply of mercury vapour ; or, instead of using an auxiliary electrode 4 &c., one of the other electrodes may be heated. A continuous current then flows between the electrodes 2, 3, the electrode 3 being the cathode. The battery 10 may then be cut out of circuit. A water jacket 12 with inlet and outlet tubes 13, 14, or other cooling- means, may be placed round the anode 2. In a modification, Fig. 2, the anode 16 is non-vaporizable, two cathodes of mercury 18, 23 being provided as before. Apparatus for utilizing the direct current is indicated at 15, 20. To prevent excess of magnetizing-current in the transformer, there may be two secondary windings supplying waves of opposite polarities to two rectifiers, and connected so as to form a three-wire system.

Patent GB-190504861-A (GB)
Title: Improvements in Railway Signalling Apparatus.
Inventor: WHEATLEY JESSE
Filed: 1905-03-08
Granted: 1905-12-07
Abstract: 4861. Wheatley, J. March 8. Detonator apparatus; audible signals; contacts, mechanical. - Relates mainly to detonator apparatus of the class in which a detonator is exploded if a train passes a signal standing at ' danger.' Adjacent to the rail is a pedal g adapted to depress a lever f so as to bring a hammer e down upon a detonator v resting on a pivoted and counterweighted anvil w. The detonators may be fed from a magazine s by means of a vibrating grid actuated by levers t, u, or any other known form of feeding- device may be employed. Exploded detonators are removed by swinging the tube s into the position shown by dotted lines by means of the wire 18. In fine weather, the signalman by means of a hand-lever connected with the wire 17 can move the weighted lever c so as to lift the link d and depress the pedal g, thus putting the detonator apparatus out of action. When the apparatus is in use, the operation is as follows :-If the signalman puts the signal 2 to ' safety,' by means of the wire 1<a>, 1, the branch wire z is also operated, and the weighted lever c turns until the spring-tensioned detent p engages with the recess q. A slip device 6 allows the wire z to become slack as soon as the lever c has been locked, although the signal wire 1 is still taut. The pedal g having been thus depressed, the detonator apparatus is out of action, but, as soon as the train has cleared the depressed pedal, it traverses a pedal rail l, Fig. 5, thereby slackening the wire o. As the last wheel of the train leaves the rail l, the weight r<#> rocks the rail back, and in so doing jerks the detent p out of engagement with the recess q, the detonator apparatus being thus put in readiness to give a 'danger' signal even though the signal 2 may still stand at 'safety.' If the signal 2 is standing at danger,' the pedal g is in the raised position, and the first wheel of a passing train depresses it and explodes the detonator, the pedal being then held depressed by the action of the detent p. The lever c is unlocked when the last wheel of the train leaves the rail l, as already described, the pedal then rising, and another detonator being fed from the magazine. The slip device 6 is shown in Fig. 3. When the wire 1<a> is pulled, the hook 12 draws the slide 7 and wire z with it until the inclines 15 are reached, when the bar 7 is released and the counterweight 9 slackens the wire z. When a gong is employed in place of detonators, the hammer e is dispensed with, the shorter arm of the lever f being connected by a rod or chain with the gong hammer.
