Title: Improvements in and relating to Electric Furnaces.
Inventor: KELLER CHARLES ALBERT
Filed: 1904-02-15
Granted: 1904-03-31
Abstract: 3790. Keller, C. A. Feb. 15. Electric furnaces. - A number of furnaces c are connected by means of channels f to a centrally - arranged accessible crucible d. The current flows to and from the hearths through vertical electrodes a, b. If, as is preferable, four furnaces are used, they are divided into two groups, which are connected with each other in series, the two forming each group being connected in parallel. The circuits are completed by the fused material in the channels f and crucible d, but in order that the circuit shall not be broken when a casting is made through the mouth i, the hearths of opposite polarity are connected by shunt conductors e. As molten material accumulates after a casting, the current again passes through it. The central crucible d may be provided with refining facilities, such as air tuyeres. To keep the temperature of the crucible sufficiently high, an adjustable vertical electrode h is provided. The furnace may be used with polyphase currents.

Granted: 1905-04-20
Abstract: 13,707. Bayliss, Jones, & Bayliss, Bayliss, H. W., and Howarth, R. June 17. Forging.-In a boltheading machine in which a heated blank is carried in a "bore" or die from the feeding position to the heading position, the heated portion of the blank is not allowed to come in contact with the metal of the bore until in the heading position, so as to lessen cooling. The heated blank is inserted in a bore C carried by a rotating table A and is prevented from entering the bore by a " tipper " D supported by a " man " F and a spring J. The table is revolved until the blank is under the heading-die, which forces the blank into the bore, until a collar E is forced against a lower frame A', and then forms the head and the neck. A cam-plate, over which the bottom of the " man " F works, may be used instead of the spring to support the bolt until just before forging.

Title: Improvements relating to Air Pressure Brakes for Vehicles
Inventor: KRAMER ERWIN
Filed: 1904-08-02
Granted: 1905-08-02
Abstract: 16,933. Kramer, E. Aug. 7, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Electric motor vehicles, brakes for. The triple valves are regulated by an electromagnetic solenoid, the effect of which varies with the angular velocity of the wheels. The valves are intended principally for street electric railways or the like. To apply the brake, the cock 22 is turned to the position shown, and the controller connects the terminals of the motor to the winding 15 of the regulating- solenoid. The compressed air then passes from the reservoir 2 through the ports 8, passage 9, and pipe 1 to the brake cylinder 3, and through the pipe 10 to the chamber 11 beneath the piston 6. The double piston 5, 6 then rises and tends to close the ports 8, this movement being resisted by the spring 20 and the electromagnetic forces induced by the current in the solenoid 15. As the core 13, under the influence of these resisting forces, falls into the iron cap 18 of the solenoid, the number of lines of force passing between the cap and the core decreases, thus lessening the electromagnetic forces tending to depress the core and to uncover the ports 8. The core consequently assumes a definite position for each strength of current, and the opening of the ports 8 and the force of application of the brakes are therefore dependent upon the speed of the rotation of the axle and the motor on it.

Title: Improvements in Cash Registers
Filed: 1904-09-26
Granted: 1905-01-05
Abstract: 20,717. National Cash Register Co., [National Cash Register Co]. Sept. 26. Receipts, checking and recording.-A cash registei, which may be of the key type described in Specification No. 10,213, A.D. 1893, is provided with two or more counters, one of which is normally operative, with adjustable means for setting another counter for operation, and with a series of special keys and means controlled by them for preventing the operation of whichever counter has been set. In the machine shown there are two independent counters 22, 22<1>, one, 22, of which is rendered operative by the pushing-in of the button 80, and the other is rendered simultaneously inoperative. A latching or locking mechanism retains the push-button 80 in its inward position until after the operation of the machine, and the push-button is locked after the operation of any key has begun. Each special key, marked " paid out," " charge," or " no sale," when depressed, throws out of operation the counter which is set for operation. This is effected by means of a cam-arm on the key-lever engaging a projection on the rock-shaft 133, Fig. 3, of the counter-controlling mechanism. A special printing- wheel is also set to print the proper designation of the special key depressed. A positive return is given to the rocking counter frames after the counters have been thrown into operative position Upon the operation of a special key, the adjusting- slide 56 is moved rearwards, but at the completion of the revolution of the main operating-shaft 40, the pin 143 strikes the lug 145 and forces the adjusting-slide forwards into normal position. The inoperative counter is positively held inoperative so that it cannot by its own weight fall into engagement with its operating-segments, and auxiliary locking-means hold the counters out of operation when a special key is operated. The indicator 195 on the shaft 194, working in connection with the push-button 80, is set for the normally inoperative counter after the pushbutton is pushed in, and the pin 185 has pressed in the arm 186, when a key is operated, so releasing the foot 197 of the lever 189, and allowing the spring 187 and the linkage gearing for the indicator to act.

Title: Improvement in Methods of Increasing the Effective Radiation of Electromagnetic Waves.
Inventor: STONE JOHN STONE
Filed: 1904-10-26
Granted: 1905-02-02
Abstract: 23,090. Stone, J. S. Oct. 30, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Telegraphs.-A method of increasing the effective radiation of electromagnetic waves from an elevated conductor consists in artificially in creasing the natural conductivity of the surface of the earth, to which the conductor is connected, for a radial distance approximately equal to a quarter wave-length of the transmitted wave. To increase the conductivity of the earth as above-mentioned, a metallic netting, shown in Fig. 1, is connected with the conductor and with the surface of the earth and is extended out radially one quarter wave-length. A modification is to employ a layer of calcium chloride or other deliquescant salt instead of the metallic netting. The rest of the apparatus in Fig. 1 is merely diagrammatic. An alternator A with transformers T, M, condenser C, self-induction coil L, and sparking gap s are employed to produce electric oscillations in the elevated conductor V. Theoretical reasons are given for the above - mentioned distance, and reference is made to Specification No. 17,703, A.D. 1902.

Title: Improvements in Arc Lamps and Electrodes therefor
Inventor: HAERDEN JOHANNES
Filed: 1904-12-09
Granted: 1905-02-02
Abstract: 26,918. HõrdÚn, J. Dec. 10, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Arc lamps.-When electrodes of or containing titanium are employed in alternating-current lamps, the arc is supplied with materials such as carbon and salts of halogens and of the light earths to maintain it at a normal voltage and current. Substances should be employed for this purpose which do not lower the melting point of the electrodes. In one method, an electrode consisting of a titanium compound such as the carbide with a small proportion of carbon is used in combination with an electrode composed principally of a more readily arcing material such as carbon, and which may have a small core similar in composition to the first electrode. The titanium carbide is made by reducing rutile in an electric furnace, and is preferably freed from iron and from silicates, although the presence of a small proportion of aluminium silicate is not prejudicial. The carbide is mixed with carbon and a binding- substance such as linseed oil or tar, moulded, and heated first in a muffle furnace and then in a carbon tube in an electric furnace. This electrode may be copper-plated before use. The core of the other electrode is pressed into the carbon shell in a plastic condition, being previously mixed with a binding-material such as water-glass or mastic ; the whole electrode is then heated in a drying-oven. Ammonium chloride, magnesium phosphate, and tar may be added to the materials used for the first electrode and for the core of the second.

Title: Improvements relating to Apparatus for Discharging Water or other Liquids by Fluid Pressure.
Inventor: WESTWOOD JOSEPH WILLIAM
Filed: 1906-06-12
Granted: 1907-05-02
Abstract: 13,439. Westwood, J. W. June 12. Feed-water, supplying.-Apparatus for discharging liquids, e.g. the condensation water from steam heating - systems, steam traps, and the like, by steam pressure, comprises a receptacle divided into upper and lower compartments a, b, by a diaphragm c, the upper part being provided with a ball valve f<1> through which the water of condensation flows into the float g and out through the valve h. Communication between the two chambers takes place through a pipe i and through a by-pass pipe connecting the upper portions of the chambers. The action is as follows :-Water passes from the upper to the lower compartment by way of the pipe i and the valve j until the accumulation of water in the chamber b raises the float n, which causes the rotation of the counterweighted shaft o through the medium of levers p, q. This shaft carries slotted links r, which cause, after a certain amount of lost motion, the closing of the valves in the pipes connecting the two chambers and the opening of a valve admitting steam to the lower compartment, thereby forcing the water through the pipe s to the boiler or other vessel. When the float n has descended sufficiently, the positions of the valves are reversed, the pressures in the two compartments are equalized, and the lower chamber commences to fill again from the chamber a. According to the Provisional Specification the valve j is a non-return valve, while the by-pass pipe terminates in the inlet pipe e which has a nozzle to direct the waste steam upon the water in the upper chamber.
