Disclosed herein is a flooring comprising a surface layer made of a synthetic resin, and a wood-based board as a base. Preferably, the surface layer includes a printed layer formed by general gravure, transfer, heat-sublimation, silk screen or digital printing using a printer, a protective made of a synthetic resin, and a UV-curable or heat-curable surface treatment layer. The wood-based board is selected from plywood, medium-density fiberboard (MDF), high-density fiberboard (HDF), particle board, and resin-wood flour composite board. The flooring may further comprise a bottom layer laminated under the wood-based board for protecting the flooring against moisture from the bottom. The flooring is cut into pieces having an appropriate size, and the pieces are processed into a finished product in a tongue and groove (T & G) shape.

Material dispensing systems and methods for make such systems are described. The material dispensing systems employ a collapsible container having at least two distinct chambers, and is at least partially surrounded by an elastically deformable band. The band stretches as the container is filled with a flowable composition, thereby creating potential energy which can then be used to dispense the composition in lieu of a propellant and/or pressurized container.

An oil separator disposed inside a cylinder head cover of an internal combustion engine. The oil separator includes a body section defining an elongate separator chamber and having a blowby gas inlet and a blowby gas outlet. A partition wall is disposed to divide the separator chamber into an inlet chamber at side of the blowby gas inlet and an outlet chamber at side of the blowby gas outlet. The partition wall is formed with a plurality of passage holes each of which is triangular in cross-section. A collision plate is disposed inside the outlet chamber and located opposite to the passage holes of the partition wall. A slit-like opening is defined by a lower section of the collision plate and communicated with a drain section for discharging oil separated from blowby gas into a valve operating chamber.

Energy absorbing fabrics that are generally flat and that have a controllable and significant elongation distance. The fabrics are comprised of elongation yarns, such as partially oriented yarns (POY), and binder yarns, where the elongation yarns and the binder yarns have various weave-in percentages depending on the desired amount of elongation. In certain embodiments, because they are generally flat, the energy absorbing fabrics are suitable for use in retractors. Also provided are processes of manufacturing generally flat, energy absorbing fabrics.

The invention discloses a compound centrifugal manufacturing method for an axial sleeve of a bushing, which comprises the following steps: smelting molten metal of an iron-based material and molten metal of a cobalt-base alloy in two smelting furnaces respectively; performing deslagging and deoxidation treatment after the melting down of the molten metal of the iron-based material and the molten metal of the cobalt-base alloy; performing centrifugal casting on the outer layer molten metal of the cobalt-base alloy first, and adding an acid slag protective agent along with the outer layer molten metal of the cobalt-base alloy when the outer layer molten metal of the cobalt-base alloy is cast to 20 to 30 percent of the gross weight of the outer layer molten metal of the cobalt-base alloy needing to be cast; passing 3 to 5 minutes after the outer layer molten metal is cast, and after solidifying the outer layer molten metal of the cobalt-base alloy, casting the inner layer molten metal of the iron-based material until finishing; and under the action of centrifugal force, cooling and solidifying the inner layer molten metal and the outer layer molten metal into a blank of a compound centrifugal axial sleeve of a bushing, and assembling and processing the blank.

A method for preventing waste materials from clogging a household drain, the method comprising: a) receiving a quantity of waste material contained in a flow of liquid toward a drain receptacle; b) guiding the flow of liquid to a predetermined position adjacent a part of a manually operable device mounted within the drain receptacle and gathering the quantity of the waste material from the flow of liquid in a first location adjacent a member of the manually operable device located in the drain receptacle; c) maintaining the quantity of waste material generally perpendicular to the vertical motion of a manually moving size reduction assembly; d) manually moving the size reduction assembly portion of the device so as to subject the quantity of waste material to abrading action, thereby producing an abraded portion of waste material as a plurality of smaller pieces; and e) carrying the abraded pieces away from the drain receptacle and through a drain conduit in the flow of water.
