Abstract: A foamed cotton mop head has a mounting member (1) having a joint portion (11) mounted on a mounting plate (12) extending downward and a foamed cotton head (2) mounted on the mounting member (1); wherein, the mounting plate (12) is inserted downward into the top of the foamed cotton head (2) and attached to the foamed cotton head (2), forming a framework for the foamed cotton head (2). The whole foam cotton head (2) is partially supported by the mounting plate (12), so that the foamed cotton head (2) is kept at certain strength, not floppy, and difficult to shake and deform during mopping. The mopping operation becomes easier, and the hand feeling is better. During the water squeezing, it is ensured that the surface of the foamed cotton head are subjected to the squeezing force evenly and difficult to deform. In addition, it is easier for the foamed cotton head to pass through the elastic bayonet of the water squeezing frame.

Abstract: This patent describes metal flake composites consisting of metal flakes and thermoplastic resins as printing materials for additive manufacturing of prototypes with metallic appearance, improved mechanical properties and durability. Metal flakes of 5 to 50 microns in average size (D50) and 0.2-2 microns in thickness are made of base metals such as aluminum, chromium, cobalt, copper, iron, nickel, tin, titanium, zinc, and their alloys, e.g., stainless steel, brass and bronze by ball milling metal powder precursors in the presence of a liquid solvent and lubricants. Thermoplastic resins such as Nylon, polystyrene, polycarbonate, acrylonitrile butadiene styrene are coated with metal flakes in a composition ranging from 0.5 to 50% by weight. The composite undergoes a bonding process to improve its adhesion and uniformity.

Abstract: A method for pushing micro-blogs is provided. The method is performed at micro-blog pushing server. In this method, a set of keywords is determined, each keyword is associated with at least one of micro-blogs received at a micro-blog receiving server, an index of the plurality of micro-blogs is created using the set of keywords, a subset of keywords, each having an interest value greater than a preset threshold, are obtained, micro-blogs associated with the obtained keywords are searched for, the searched out micro-blogs are sorted based on a timeline or based on relevancies of the micro-blogs to the keywords having interest values greater than a preset threshold, and then the sorted micro-blogs are pushed to the user. In addition, an apparatus, a system and a non-transitory computer-readable storage medium related to the method are also provided.

Abstract: The present invention discloses a method and apparatus for storing node, pertaining to the field of the Internet communications. The method includes: receiving a write operation request and a node from a client; storing the node in a memory and setting the update time of the node as the time of receiving the node; and relocating one or more nodes from the memory to a file according to the update time of each of the nodes in the memory. The apparatus includes: a receiving module, a storage module, and a relocating module. The present invention can reduce the frequency of loading and relocating nodes to and from a memory, and improve performance of a server.

Abstract: The invention discloses a method for storing data and a device of implementing the same. The method comprises receiving a request for storing data sent by a user and storing the data to an SSD according to the received request. The device comprises a request receiving module used to receive the request storing data and an SSD storage module used to store the data to an SSD according to the received request. The invention ensures consistency of data storage by storing data to an SSD according to the received request, thereby reducing data redundancy caused by using a cache layer to cache the data in the prior art. Additionally, the use of a single layer of an SSD to store data avoids the need of reloading data in the cache layer once a machine is power-down, thereby reducing the complexity of system design and the cost of operation and maintenance.

Abstract: A double-sided exchange may be an exchange wherein both buyers and sellers provide bids for matching via the exchange. A first interface receives buy bids from buyers and a second interface receives sell bids from sellers. A controller matches the sell bids with the buy bids, yielding matched buy bids and matched sell bids in response thereto so that allocations of the matched buy bids and the matched sell bids maximize a surplus of the exchange. An allocation that substantially maximizes an auctioneer's profit and/or announces payments based on sell bids is provided. The announced allocations and prices can be shown to be a substantially competitive equilibrium in some applications.

Abstract: A method for producing porous metal plated polymeric foam having uniform pore properties. Polymeric foam buns are horizontally cut along a longitudinal surface thereby lifting off a foam sheet. The sheet is spooled and then reticulated to remove any remaining cell walls and to round off the internal pore struts to enlarge the openings between the adjacent cells. The reticulated foam sheet is unwound and then plated. Slabs may be attached end to end and loop slitted and then reticulated. The resulting plated uniform foam provides a superior substrate for battery plaques and other applications.
