摘要:
A desalination process for the production of potable water comprising the steps of extracting at least one distillate stream 150 from at least one higher temperature stage 109 of a Multistage flash distillation (MSF) separation process 100 and supplying said at least one distillate stream to at least one stage of a separation process 200 operating at a lower temperature than said higher temperature so as to maximise the use of sensible heat in said distillate stream by heat transfer in said at least one stage, to lower the external heat input of said at least one stage and of the process overall. The distillate stream is used to provide additional heat exchange to a multiple effect distillation (MED) process 200, a reverse osmosis system (not shown) or to preheat the feed stream of the MSF process.
摘要:
A process and apparatus for separating suspended solid material from a fluid, comprising the steps of adding in a chamber buoyant media as glass spheres with 30-250 micron diameter (106) to the fluid to form a first mixture of fluid influent and buoyant media, adding a flocculant (108) to the said first mixture to form a second mixture of influent, buoyant media and flocculant, transferring said second mixture to a flotation chamber (200), introducing a pressurised fluid (203) to the second mixture in said flotation chamber, removing separated floating sludge from said flotation chamber, and removing separated clarified effluent from said flotation chamber. Optionally, a coagulant may be added after the flocculant.
摘要:
A yarn feeder includes a switching mechanism for switching the position of a yarn feeding port, the switching mechanism further including a push-in operation member switchingly operating the height position of the yarn feeding port in association with entraining means, and the push-in operation member includes a pressing operation panel setting a yarn feeding position where the yarn feeding port mostly nears the knitting needle and an intermediate position where the yarn feeding port is positioned above the yarn feeding position and nearest the movable knitting member, so that a withdrawal position where the yarn feeding port is not operated by the push-in operation member, the intermediate position, and the yarn feeding position are formed in that order from the top, and the lift of the yarn feeding port is drivingly connected with the forward and backward movements of the movable knitting member so that the movable knitting member is retracted to open the mouth, the yarn feeding port lowers to the yarn feeding position, and at the intermediate position, the movable knitting member moves forward to a mouth clearance portion to close the mouth.
摘要:
There are disclosed methods (processes) and systems, for: 1. establishing and defining service classes and service plans; 2. monitoring and controlling parameters related to level of service for each service class; and 3. estimating the additional resources necessary to support excessive traffic demand. These methods and systems provide visibility into the network, enabling management of the network. In particular, presented is a method for service management in cellular networks based on monitoring flow control signalling, tHe method comprising the steps of: -defining and identifying service classes (301); -defining flow parameters parameters per service class (303); -defining service level parameters per service class (305); and, -creating service plans (307).
摘要:
A wheel bearing device to ensure a sufficient durability and life even with the application of bending moment acting on the wheel bearing device. An outer joint member (41) of a constant velocity joint is fitted into the inside of a wheel hub (10) and a portion thereof is swaged radially outward by plastic deformation to unite the wheel hub and the outer joint member. The outer joint member (41) includes a pilot part (35) adjacent the plastically deformed portion, and the ratio of an inside diameter Φd2 of the pilot part to an inside diameter Φd1 of the plastically deformed portion is set 1.110 or less.
摘要:
The invention provides a hanger (1) with clips (4) that has a hook (2) at its center and clips (4) at ends, respectively, of an arm part (3) extending rightward and leftward from the hook (2). The clip (4) consists of a pair of clip pieces (4a). One clip piece (4a) is formed integrally with the arm part (3), and the other clip piece (4b) is molded in a state of being joined to the one clip piece.
摘要:
There are disclosed systems and methods for dynamically managing resources, such as bandwidth and delay in networks, such as cellular networks. These systems and methods dynamically and automatically adjust the bandwidth and delay in individual shares access media or cells 'on the fly', to optimize user experience, usage and packet transmissions in the network.
