Title: A Method of Uniting the Ends of Rails, Girders and other Parts of Iron and Steel Structures.
IPC: B23K35/00
Filed: 1912-07-10
Granted: 1913-04-03
Abstract: 16,165. Goldschmidt Akt. - Ges., T. July 28, 1911, [Convention date]. Soldering; welding; thermo-aluminic processes.-The ends of rails, girders, or other iron and steel structures are united by a layer of carbon-free metal such as copper, silver, nickel, or alloys thereof, such as bronze or of copper-plated or nickel-plated iron sheets instead of ordinary sheet metal, as described in Specification 18,328/99, the work and intermediate layer being heated, and the work being immovably fixed so that the pressure to effect the weld is produced by the expansion of the work. The welding may be effected by the alumino-thermic process in which aluminium or calcium-silicon, silicon-magnesium, aluminiumcalcium, &c. may be used, or by the use of hot gases blown through a mould surrounding the joint, or by electric heaters of the resistance type. The alumino-thermic processes may be carried out in either of two known manners. In one process the resulting molten slag and iron is poured over the rim of the crucible into the mould so as to obtain a thin layer of slag on the work and thus prevent the molten iron from coming into contact with the work and thus to obtain a uniform union over the whole cross-sectional area. In the second process, molten metal is run out of the bottom of the crucible into the lower part of the mould to form a fusion weld at the foot of the rail, the intermediate metal being inserted only between the head and web portions, and being heated by the slag. The ends of the rails are mechanically cleaned and evenly dressed before inserting the intermediate metal so as to ensure a good contact. The parts may be butt-welded or lap-welded, the parts having bevelled ends or being provided with male and female joints, or with scarf joints, for example where half the thickness of each is removed ; in this latter case the longitudinal faces may also be joined.

Title: Improvements in and relating to Electric Recording Devices.
IPC: G01R13/04
Filed: 1913-03-07
Granted: 1914-03-09
Abstract: 5734. British Thomson-Houston Co., [Allgemeine Elektricitõts Ges.]. March 7. Electric marking-action.-In a device, especially applicable for recording signal positions and railway operations, different co-operating processes are recorded in different colours or shades of colour, which are produced by different electrolytes, or by the same electrolyte with electrodes of different metals, or by different strengths of electrolyzing current. Suitable electrolytes are potassium ferrocyanide and potassium iodide, the former giving red, blue, and green records with positive electrodes of copper, iron, and steel respectively. A number of forms of apparatus are described. Fig. 2 shows a recorder for indicating the positions of a signal, having two electrodes e1, e2 of different metals, which are energized alternately by means of a switch k, the latter being operated by the signal. The full and dotted lines 1 and 2 represent respectively red and green lines corresponding to the raised and lowered positions of the signal. The circuit is completed by the conveying cylinder t. The electrodes e1, e2 may be on opposite sides of the strip, the current through them being reversed, markings of different colourations being thus produced on opposite faces of the strip. In another form, parallel strips of paper soaked in different electrolytes pass beneath electrodes of the same metal. In the apparatus shown in Fig. 4, a resistance w is placed in the circuit of the electrode e2, which thus produces a weaker colouration than the electrode e1. Other forms are described in which the circuit through a single marking electrode is varied by alteration of the resistance or voltage of the circuit. Further colouration may be obtained by increasing the current-strength sufficiently to burn the record line. Two electrodes giving different colourations may be alternately brought into contact with the record-strip, for example as shown in Fig. 10, in which electro - magnets m, m<1> alternately attract an armature c attached to electrodes e, e<1>, which produce an unbroken line of two colours. An alarm may be given when the current in the recording circuit fails, and a special mark may be made showing the duration of the interruption, as in the apparatus shown in Fig. 12, in which two electrodes e1, e2 are placed in the alarm circuit, which is completed by a switch arm d when this is no longer attracted by the electromagnet m<11>, owing to the failure.
