The invention provides chain extenders made from epoxy-functional (meth)acrylic monomers and styrenic and/or (meth)acrylic monomers. The invention further provides polymeric compositions made from the chain extenders and plastic articles made from the compositions. Finally, the invention provides methods of using the chain extenders to improve the properties of virgin, recycled, and reprocessed condensation polymers.

Cards made in accordance with the invention include a specially treated thin decorative layer attached to a thick core layer of metal or ceramic material, where the thin decorative layer is designed to provide selected color(s) and/or selected texture(s) to a surface of the metal cards. Decorative layers for use in practicing the invention include: (a) an anodized metal layer; or (b) a layer of material derived from plant or animal matter (e.g., wood, leather); or (c) an assortment of aggregate binder material (e.g., cement, mortar, epoxies) mixed with laser reactive materials (e.g., finely divided carbon); or (d) a ceramic layer; and (e) a layer of crystal fabric material. The cards may be dual interface smart cards which can be read in a contactless manner and/or via contacts.

Cannulas, as well as cannula assemblies including gas filters, are disclosed.

Truss cable semi-submersible floater for offshore wind turbines and construction methods are provided. A floating system includes a hull, a tensioned cable system, and a tower. The hull includes vertical buoyant columns with one column at the center of the pattern, larger size column base tanks, and a truss system, all of which are coupled to each other for supporting the tower and wind turbines. The column can be made of hybrid materials, including steel and composite-concrete. The steel section and the composite-concrete section of the column can be connected by grouting. The tensioned cable system including upper, lower, and diagonal tensioned cables to connect the column, the column base, and the tower to reduce the bending moments and improve stability, strength and dynamic performance of the hull structure.

A cell module has a cell group with a plurality of cells connected to each other. The module comprises a bus bar plate including a bus bar connecting between the cells and an end cover for covering the bus bar plate. The cell module is configure to be fixed with the end cover.

A conductive layer, a metal layer and a doped layer are sequentially formed on a glass substrate. A CMOS circuit region, a transistor region, a reflective region, a transmission region and a capacitor region are defined. Next, a polysilicon layer and an insulating layer are formed to serve as a source/drain region, a channel region and a gate insulating layer. Then, a resin layer with a rough surface is formed. Next, a metal layer is formed to serve as a gate structure and a reflective electrode. Then, an ion implanting process is performed to form the source/drain structure of a PMOS. Then, a passivation layer is formed to define a transmission region. Finally, the metal layer and the doped layer are removed to expose the conductive layer.

The invention belongs to the technical field of high molecular materials, and relates to a composite polyolefin material, a preparation method and a use of the composite polyolefin material. The material comprises 9 parts of an outer layer flame-retardant polyolefin material and 1-4 parts of an inner layer reinforced polyolefin layer, wherein the outer layer flame-retardant polyolefin material is prepared from the following components in parts by weight: 50-80 parts of polyolefin 1, 0-30 parts of a filler 1, 16-35 parts of a fire retardant, 0-9 parts of a flame retardant synergist, 0.1-0.4 part of an antioxidant 1 and 0.1-0.4 part of a lubricating agent 1; and the inner layer reinforced polyolefin layer is prepared from the following components in parts by weight: 50-80 parts of polyolefin 2, 0-45 parts of a glass fiber, 0-30 parts of the filler 2, 0-5 parts of a graft, 0.1-0.4 part of an antioxidant 2 and 0.1-0.4 part of a lubricating agent 2. The material has the advantages of being low in cost, light in weight, good in toughness balance, changeable in size and fireproofing, and being capable of being used for a plurality of times.

An innovative one-piece videolaryngostroboscope that provides slow motion visualization and detailed analysis of the vocal cords movements, which are imperceptible to the naked eye due, by means of a video camera with stroboscopic; said apparatus is used to perform examinations in patients, aiming to assess the incidence of larynx cancer. The invention including a processor base; an optics tube with a built-in light sources, a built-in video camera; a microphone, an auxiliary pedal and software.

A method for producing nano-scale theta (θ)-phase alumina microparticles is disclosed. The nano-scale θ-phase alumina microparticles are uniform in particle size and highly phase-pure. They are obtained by controlling the ratio of boehmite mixed with the θ-phase alumina initial powders, followed by at least one phase transformation. Therefore, the nano-scale θ-phase alumina microparticles produced by the present method have more uniform particle size and highly purer phase. As such for the production of nano-scale θ-phase alumina microparticles, the present method saves more process time and cost, and it provides an advantage such as the clean production.

The invention relates to a valve ball type check valve. The valve ball type check valve comprises a valve body, wherein an inlet and an outlet which are used for being connected with adjacent pipelines are arranged on the valve body; a valve seat and a ball sleeve are arranged in the valve body; a valve ball body matched with the valve seat is arranged in the ball sleeve; the valve ball body is movably arranged in the ball sleeve; an overflow port communicates with the outlet and is arranged on the ball sleeve; and the axes of the valve seat and the ball sleeve are obliquely arranged relativeto the inlet direction and/or the outlet direction of the valve body. According to the valve ball type check valve, whether the valve ball type check valve is vertically installed, horizontally installed or obliquely installed at a proper angle, the ball sleeve can be kept in an oblique state, the valve ball can move towards the valve seat by virtue of self-weight, and the reliable closing of a valve port is guaranteed; and compared with the prior art, the valve ball type check valve can adapt to different installation angles, is good in universality and wide in application range, and can fully exert the characteristics of simple structure, low cost, reliable performance and convenient maintenance.
