2. H0f gauge - Wikipedia

   en.wikipedia.org/wiki/H0f_gauge

   H0f. H0f gauge, occasional as H0i [1] gauge designated, is a rail transport modelling scale representing Feldbahn -style 2 ft and 600 mm gauge railways using 1:87 HO scale running on Z gauge 6.5-millimetre (0.26 in) track. [2] The Normen Europäischer Modellbahnen NEM 010 specification defines H0f for modelling gauges 400–650 millimetres (16 ...

3. HO scale - Wikipedia

   en.wikipedia.org/wiki/HO_scale

   Model gauge. 16.5 mm ( 0.65 in) Prototype gauge. Standard gauge. HO or H0 is a rail transport modelling scale using a 1:87 scale (3.5 mm to 1 foot). It is the most popular scale of model railway in the world. [ 1][ 2] The rails are spaced 16.5 millimetres (0.650 in) apart for modelling 1,435 mm ( 4 ft 81⁄2 in) standard gauge tracks and trains ...

4. Digital model railway control systems - Wikipedia

   en.wikipedia.org/wiki/Digital_model_railway...

   Digital model railway control systems are an alternative to control a layout and simplify the wiring and add more flexibility in operations. A number of control systems are available to operate locomotives on model railways. Analog systems where the speed and the direction of a train is controlled by adjusting the voltage on the track are still ...

   en.wikipedia.org/wiki/Railroad_switch

   Abt switch used in the 1895-built Dresden Funicular Railway (photo of 1985) A railroad switch ( AE ), turnout, or [ set of] points ( CE) is a mechanical installation enabling railway trains to be guided from one track to another, such as at a railway junction or where a spur or siding branches off.

6. Micro process engineering - Wikipedia

   en.wikipedia.org/wiki/Micro_process_engineering

   Micro process engineering. Micro process engineering is the science of conducting chemical or physical processes ( unit operations) inside small volumina, typically inside channels with diameters of less than 1 mm (microchannels) or other structures with sub-millimeter dimensions. These processes are usually carried out in continuous flow mode ...

7. Mesoscale manufacturing - Wikipedia

   en.wikipedia.org/wiki/Mesoscale_Manufacturing

   Manufacturing Classification. Mesoscale manufacturing is the process of creating components and products in a range of approximately from 0.1mm to 5mm with high accuracy and precision using a wide variety of engineering materials. Mesomanufacturing processes are filling the gap between macro- and micromanufacturing processes and overlaps both ...
