In a modification the coupling portions 8, 10 may be interchanged. A square, preferably insulating plug 7 is fixed to the sleeve 29 and is located in an insulating fitting 15 on the appliance by an indexing ball 17. The motor supply leads, which may be combined with the silk braid of the flexible lead, are connected to sockets 22, 23 engag- :ing contact pins 30 which may be simply short circuited or connected at will by a sliding switch member in a channel 32. Alternatively the cover 27 on the flexible shaft end may be rotatable to produce switching. In a modification, Fig. 4 (not shown) a switch (see Group XXXVII) including a series connected manual switch, is carried on the flexible shaft end and has a projecting slidable rod which is operated when the two coupling halves are assembled. Alternatively, the switches may be fixed to the driven appliances and toggle-type switches may be used. If a high voltage motor is desired a step down transformer fed relay circuit may be energised by the engagement of the coupling, a manual switch being included as before or a flexible thrust wire can be used to operate a switch within the motor casing, a manual control also being fitted.

[Class 39 (i)] A discharge device has an inductive stabilizing reactance and a bimetallic thermostatic switch through which current passes to heat one of the electrodes, the thermostatic switch being arranged to be operated by heat conducted from the heated electrode when the desired electron - emitting temperature is reached, to initiate a high voltage surge in the stabilizing reactance which starts the discharge. As shown, a discharge lamp has two electrodes 2, 3, heated by the discharge during operation, electrode 2 being heated initially from the supply mains through an inductance (not shown), leads 4, 5, contacts 10, 8, a U-shaped bimetallic strip 7 and lead 6. When the electrode 2 reaches the desired temperature, heat conducted through the lead 6 operates the switch, separating contacts 8, 10 and interrupting the current through the electrode 2 and producing a voltage surge in the inductance to start the discharge. To prevent excessive bending of the strip 7 during operation of the device, a stop is provided, such as a glass sleeve 9 on a portion of the lead 5. The lamp may be enclosed in an evacuated envelope containing the switch.
