  • Patent number: 6318133
    Abstract: A washing machine includes a washing shaft for rotating agitating blades disposed in a dewatering tank, and the washing shaft is disposed coaxially on a hollow dewatering shaft for rotating the dewatering tank. The washing shaft is connected to the output side of a reduction mechanism, and a washing side input shaft is connected to the input side of the reduction mechanism to rotate the washing shaft by decelerating the rotation of a drive motor. A rotor of the drive motor is coupled to the lower part of the washing side input shaft. Therefore, the rotating torque of the agitating blades can be increased without increasing the torque of the drive motor. In addition, if the laundry collides against the agitating blades, the eccentricity to the washing side input shaft is suppressed, thereby the increase of the washing capacity can be handled without increasing the size of the drive motor.

  • Patent number: 6314973
    Abstract: A flushing accessory for connecting a supply of domestic fresh water to the cooling jacket of a marine outboard engine for the purpose of flushing saline residue therefrom. The accessory includes a conventional “earmuffs” assembly which self-adheres to the lower unit of the outboard engine once installed thereon and a long handle enabling the accessory to be installed from within the boat. The handle is hollow, and conducts water from the domestic supply to the “earmuffs” assembly. A connector rigidly and permanently attaches the “earmuffs” assembly to the handle in an orientation such that the axis of the handle is offset from the “earmuffs” assembly. The connector is configured such that a short connector hose conducting water from the handle to the “earmuffs” assembly is disposed in close proximity to the accessory, and is not obliged to form a severe bend.

  • Patent number: 6311704
    Abstract: The present invention is directed to an apparatus for injecting cleaning materials into the steam chest of a turbine and to methods for cleaning high pressure turbine using that apparatus. The apparatus enables chemical foam to be input to the turbine through an existing port by temporarily replacing a valve attached to the steam chest. The apparatus, once attached to the steam chest, is free of moving parts, yet permits injection of chemical foam through any one or more of the steam chest apertures. The apparatus includes a housing, together with a plurality of inlets, one of which is in fluid communication with a telescoping injector for sealing engagement with a steam chest aperture. In the methods of the present invention, chemical foam may be directed through any one or more of the steam chest apertures into the turbine blade sections by operation of the remaining governor/control valves.

  • Patent number: 6309468
    Abstract: A cleaning device (2) which can be moved backwards and forwards in a swimming pool (1) has a drive mechanism which can be switched to forward or backward travel and has one motor for a left-hand-side and one for a right-hand-side part of the drive mechanism and a control apparatus for controlling the drive mechanism. The control apparatus has a speed regulation apparatus for each part of the drive mechanism and has means for differentially controlling the speed of the two motors. The cleaning device has means on both parts of the drive mechanism for measuring the distances (d1, d2) covered in forward and backward travel. The angles (R1, R2) of change of direction are calculated and differentially controlled by the control apparatus on the basis of the measured distances (d1, d2) covered and an offset width (v) of the respective travel tracks.

  • Patent number: 6305392
    Abstract: A method and apparatus for desorbing processing liquid from a processing liquid delivery line is provided. Non-thermal energy, such as ultrasonic energy or electromagnetic energy, is applied to a processing liquid delivery line. The non-thermal energy may be applied directly to the processing liquid delivery line, or may be applied indirectly via a conducting medium which distributes the energy along the length of the processing liquid delivery line. When non-thermal energy in the form of electromagnetic energy is employed, the frequency of the electromagnetic energy is adjusted to match the vibrational frequency of the absorbed molecules of processing liquid.

  • Patent number: 6293289
    Abstract: A vent for a dishwasher provides a valve with dual actuation, either to be electrically actuated according to a cycle of the dishwasher so as to close during periods of high noise generation, typically the wash cycle, and opened during the dry cycle, or to be actuated independently of the cycle under pressure differences such as may be caused by interruption of the dishwasher cycle and opening and closing of the dishwasher door such as may cause a pressure surge as the introduced cool air is rapidly heated in the interior of the dishwasher.

  • Patent number: 6289908
    Abstract: A double, front loading, dishwasher comprising two side-by-side dishwashing cabinets each provided with a washing arm and either a common pump and motor or an individual pump and motor is described. Preferably, the dishwasher is designed to fit into an existing kitchen cabinet and even more preferably into an eye level kitchen cabinet so that while one cabinet is used to store clean dishes and cutlery the other cabinet is available to load and wash another set of dirty dishes. Storage of a set of clean dishes in the dishwasher saves time as the step of unloading the dishwasher to a separate storage cabinet is eliminated, as the clean dishes may be unloaded directly to the table.

  • Patent number: 6286344
    Abstract: A washing machine with a tilted tub assembly is disclosed. In the washing machine, the tub assembly is suspended and supported within an upright housing at a predetermined angle relative to the perpendicular of the housing. The tilted position of the tub assembly within the housing is stably held by damper hangers, shock absorbing units and/or elastic support units. The tilted tub assembly is convenient to users while putting or taking laundry into or out of the tub assembly. The tilted tub assembly also forms complex and active water currents suitable for preventing laundry from being entangled during a washing operation. The washing effect of the washing machine is thus improved with a reduced deviation of the washing effect. The washing machine almost completely prevents its drive motor from being overloaded and conserves the operational time while washing laundry. This saves water and electric power during a washing operation.
