Title: Improvements in Systems of Electric Distribution by Means of Rectified Alternating Electric Current and in Apparatus therefor.
Filed: 1905-06-02
Granted: 1906-05-31
Abstract: 11,627. British Thomson-Houston Co., [General Electric Co.]. June 2. Converting alternating and direct currenta; distributing; lighting, systems of.-A series circuit requiring practically constant current is supplied through a vapour rectifier and adjustable transformer from a constantpotential alternating-current source. The anodes 8, 9 of the mercury rectifier 1 are connected through reactances 10, 11 to the terminals 6, 7 of the floating secondary coil 5 of the transformer 2, and the mercury cathode 12 is connected through the high reactance 13 and series translating - devices 14 to a tap 15 from the centre of the secondary coil 5. The starting- electrodes 16, 17 are fed through a reactance device 20 by the low-tension secondary coil 18 of a transformer, the primary coil 19 of which is connected to the constant-potential source 3. The reactance device 20 is also connected through a reactance 22 to the cathode 12. The reactances 10, 11 may be omitted, or replaced by small resistances if the transformer secondary coil 5 is suitably constructed. The reactance 20 and transformer 18, 19 may be combined as shown in Fig. 5, the two-sectioned primary coil 19<1> being connected to the constantpotential source and the similar secondary coil connected to the anodes 16, 17 and, through a tap and reactance 22', to the cathode 12. Each anode 8, 9 is enclosed in a separate narrow chamber separated by a considerable distance from the mercury cathode and shielded by a bend from the direct cathode blast ; there is a mercury condensation chamber 41, and the cathode consists of an amalgam of a refractory metal, e.g., gold or silver, which reduces the vapour tension of the mercury. A higher magnetic density than usual in constantcurrent transformers of the tub type is employed, and the angular relation between the weightsupporting arm 38 and the lever arm 39 is such that the transformer will deliver from its secondary coil 5 a current tending to decrease slightly in quantity as the voltage of the consumption circuit decreases.

Patent GB-190701277-A (GB)
Title: Improvements in Electric Switches.
Filed: 1907-01-17
Granted: 1908-01-16
Abstract: 1277. British Thomson-Houston Co., [General Electric Co.]. Jan. 17. Cut-outs; switches.-An electric switch has its contact surfaces immersed in insulating liquid and greatly extended, to reduce the temperature of the arc by diffusing it. To ensure that all portions of the contact part at the same instant, interlocking projections are formed on the co-operating contacts, parallel with the edges, and the contacts move so that their edges always remain parallel, and means are provided to give a quick break. Further, one contact, by co operation with the oil-chamber walls, produces a partial vacuum, and draws oil between the contacts on opening circuit. A frame 2, bolted to a panel 1, carries the hand-lever 3 and an electro-responsive device 5, the latch 4 of which engages the lever 3 and holds the switch " in." Two parallel frames 10 have upwardly - extending slotted members united by a pin 11. From this piu, two links 12, 13 depend so as to form a toggle, the centre of which is connected by the links and levers shown to the handlever 3. The lower end of the link 13 supports a pin which carries rollers 14, working in the slots in the side frames, and which also passes through a projection on a yoke 15. The roller-pin and pin 11 are linked by a spring, shown in tension. From the yoke 15 depend rods 16 working in guides 17. The lower ends of the rods support the movable contact 20 by means of a frame 18 and a shaped block 19 of soapstone or other insulator. A stranded cable connects the contact 20 to the circuit. An iron frame 25 is fixed to the switch frames 10, and carries insulators 24 on which the second contact 22 is mounted. Both contacts 20, 22 have grooves and projections 21, 23 formed parallel to their contact edges and adapted mutually to engage and interlock. A tank 29, with an insulating-lining, contains the oil or other insulating-liquid. Extending outwardly from the frame 25, are wings 27 arranged between the frame and the oil-chamber walls. The central lower portion of this wing is hinged to form a valve 28 opening only in the direction shown. The soapstone block 19 is shaped so as almost to touch the oil-chamber wall, and extends downward to fill most of the space between the contact 22 and this wall. Thus, a piston and cylinder are provided having a valve 28. To open the circuit, the latch 4 is tripped and the toggle 12, 13 thus released. The spring draws the contacts 20, 22 apart, their interlocking grooves ensuring parallel separation. The motion of the block 19 causes the valve 28 to close, so that partial vacuum is formed, resulting in a rush of oil across the gap between the contacts, which extinguishes the arc.

Title: Improvements in or relating to Electric Cranes, Winches and the like.
Filed: 1907-02-16
Granted: 1907-12-31
Abstract: 3908. Sunderland Forge and Engineering Co., and Blair, W. Feb. 16. Cranes; winches; brakes. - Relates to electric cranes, winches, &c and consists of an interlocking device for returning the motor controller lever to its 'off' position on the operation of the brake lever before the brake is actually applied. Suitable links &c. are connected at one end to the brake lever, and adapted at their other ends to engage suitable guides arranged at each side of the controller spindle ; they also have suitable projections &c. adapted to engage and disengage the controller lever. Normally, when the brake is off, the links are in such a position that the controller lever can be operated in either direction. When, however, the controller lever is in any of its 'on' positions, and the brake lever is operated, the controller lever is returned to the 'off' position and the continued operation of the brake lever applies the brake. The controller casing is arranged horizontally as at a, so that the operating-lever b in its normal position is vertical and projects downward. At each side of the lever is arranged a double link c having its lower end pivoted at d on a cross-bar e connected to the brake lever f, and its upper end provided with rollers g, k, of which the roller g works in guide-slots h, while the projecting roller k is adapted to engage a web m on the back of the controller lever. The guide-slots h are shaped with lower straight vertical portions n, arranged so that when engaged by the rollers g, the rollers k, k just clear the web m, while the upper portion of the guide-slots diverge and afterwards converge as shown. When the lever b is in an 'on' position and the lever f is depressed to apply the brake, the links c are lowered, and the rollers k, engaging with the web m, return the lever to its off' position when it is disengaged, and further depression of the brake lever applies the brake, there being sufficient range of movement so that the brake is not applied until the lever b is fully returned to its 'off' position.
