  2. Mattydale lay - Wikipedia

    en.wikipedia.org/wiki/Mattydale_lay

    [3] [4] [5] There are several different types of "hose loads" in use, which is the way the hose is folded in the lay: Accordion load – The hose is loaded so that when it is flat, it is standing on end. The finished load resembles an accordion. Flat load – The flat hose is simply placed in the track so that it is stacked.

  3. Preload (engineering) - Wikipedia

    en.wikipedia.org/wiki/Preload_(engineering)

    It is also used in testing a specimen, for a process where the crosshead moves to load the specimen to a specified value before a test starts. Data is not captured during the preload segment. When tensile specimens are initially placed into testing grips, they can be subjected to small compressive forces. These forces can cause specimens to ...

    en.wikipedia.org/wiki/Eurocode_1:_Actions_on...

    In the Eurocode series of European standards (EN) related to construction, Eurocode 1: Actions on structures (abbreviated EN 1991 or, informally, EC 1) describes how to design load-bearing structures. It includes characteristic values for various types of loads and densities for all materials which are likely to be used in construction.

    A preconnected attack line that is typically 1¾" diameter, and stored either on the front bumper of the apparatus or in an exterior (exposed) side well. Trash lines are typically shorter length than cross-lays , and are intended for use against dumpster fires, etc., where a longer length of hose (and consequent rebedding after the suppression ...

  6. Spot network substation - Wikipedia

    en.wikipedia.org/wiki/Spot_Network_Substation

    The transformers are wired together on the secondary side. The system is arranged so that nearby transformers do not use the same feeder. In case of an issue with a feeder (or transformer) the load is fed by nearby transformers, so there is no interruption, although a voltage drop for said load may then be present.

  7. Ring circuit - Wikipedia

    en.wikipedia.org/wiki/Ring_circuit

    Ideally, the ring circuit acts like two radial circuits proceeding in opposite directions around the ring, the dividing point between them dependent on the distribution of load in the ring. If the load is evenly split across the two directions, the current in each direction is half of the total, allowing the use of wire with half the total ...

  8. Standard streams - Wikipedia

    en.wikipedia.org/wiki/Standard_streams

    Standard input is a stream from which a program reads its input data. The program requests data transfers by use of the read operation. Not all programs require stream input.

  9. Ancillary services (electric power) - Wikipedia

    en.wikipedia.org/wiki/Ancillary_services...

    Consumer loads expect voltage within a certain range, and the regulators require it be within a certain percent of the nominal voltage (for example, in the US it is ±5%). Reactive power can be used to compensate the voltage drops, but must be provided closer to the loads than real power needs (this is because reactive power tend to travel ...
