    摘要: An improved UPS/CPS system employs a high-efficiency uninterrupted power supply function integrated with an engine-generator set that combines both short term protection against momentary power interruptions with longer term power generation. Feedback from a controller provides for improved voltage regulation during abrupt load changes and flexibility of application. A number of features and operating modes are disclosed. In one embodiment, the system is useful as a kit to retrofit existing backup power facilities.

    摘要: An auxiliary power supply system includes an internal combustion engine driving an alternator the output of which is rectified and supplied to DC bus lines across which a storage battery is connected. The DC bus lines may supply a consuming device such as an uninterruptible power supply or telecommunications system. The voltage across the bus lines is sensed and when the voltage drops below a selected value, indicating that the consuming devices is drawing power from the battery beyond a desired limit, the engine is turned on for a period of time to warm it up, during which the power from the generator is not supplied to the DC bus lines. Thereafter, the generator supplies power to the DC bus lines to supply the consuming device and partially recharge the battery until the consuming device is no longer drawing power, after which the engine is shut off. The power supply system includes a controller which monitors the intervals of time between turn-ons of the engine and if a selected period of time is exceeded, the engine is started without supplying power from the generator to the DC bus lines to allow the engine and generator to warm-up, enhancing maintenance of the system. The operating characteristics of the engine and generator are sensed and stored for access by an operator and warnings are provided if these conditions exceed acceptable limits.

    摘要: The positive positioning means of the tufting machine of the present invention prevents lateral movement of the backing material as it passes beneath successive rows of tufting needles so that the rows of tufts are accurately positioned, relative to each other and to the backing material. This machine is particularly adapted for forming narrow or fine gauge pile fabrics, such as upholstery fabrics, carpet and the like wherein the rows of tufts are closely spaced. The positive positioning means includes a pair of endless chains having upper reaches supported for movement transversely of and adjacent opposite ends of the rows of tufting needles. Gripping means is carried by the chain for engaging the side edge portions of the backing material and for positively maintaining the lateral position of the backing material as it is moved beneath the successive rows of tufting needles.
