    • There is provided a method of controlling a pedal cycle and a pedal cycle incorporating the same. The pedal cycle has an electro-mechanical drive arrangement including a continuously variable ratio transmission system having an input which is mounted to rotate about the axis and an output connected to rotate with a hub member, the transmission system comprising an epicyclic gear set including a sun gear in mesh with a plurality of planet gears mounted to rotate about respective planet shafts carried by a common carrier, which is mounted to rotate with the input about the axis, the planet gears being in mesh with an annulus gear, which is connected to rotate with the hub member. Only the sun gear may be connected to rotate a rotor of an electrical machine or an additional machine may be provided. The electrical connections of the stator of the electrical machine are connected to a controller; the method may include the step of applying a time division multiplexed control algorithm to the electrical machine, wherein the time division multiplexed control algorithm alternates between a first control mode in which current generated by the electrical machine is monitored to infer torque applied to the crank arms of the cycle and a second control mode in which the current in the input electrical machine is controlled using the inferred torque.

    • The invention relates to an installed fire extinguishing apparatus, which has a pressure-resistant storage body (10) with an internal space (11) for accommodating the fire extinguishing material composition (1) transportable in a pipeline, at least one dispersion device (3), and at least one transport pipeline (20) which is suitable for transporting the fire extinguishing material composition (1) from the internal space (11) of the storage body (10) to the dispersion device (3) arranged at the use location (2), where the storage body (10) is formed by a long pipeline (C) or a pipeline (C) that returns on itself that has a straight line main axis (T) or a main axis (T) of another shape, a trigger part-unit (4) is installed in the transport pipeline (20), and the storage body (10) is connected to a filling fitting (6) serving for filling the fire extinguishing material composition (1) or the components of the fire extinguishing material composition (1) into the internal space (11) of the storage body (10), the storage body (10) is coupled with at least one gas vessel (30), the internal space (31) of the gas vessel (30) is connected to the internal space (11) of the storage body (10) with a connection line (32) that permits the flow of medium, the gas vessel (30) and/or the storage body (10) and/or the connection line (32) has a valve (33) that influences the flow of medium between the gas vessel (30) and the storage body (10). The characteristic feature of the invention is that when the fire extinguishing apparatus is in a condition ready for use, more than 94% of the internal space (11) of the storage body (10) is filled with fire extinguishing material composition (1), where the composition (1) has a liquid and a gaseous component, and at least a part of the external surface (12) of the storage body (10) is surrounded by a material that reduces temperature fluctuations (5).
