A cut resistant chemical handling glove that is flexible and lightweight comprises a cured, liquid-impervious polymeric latex shell. A tacky acrylic adhesive with low shear strength can be used. A cut resistant liner is slipped on the tacky adhesive coating and is infiltrated with a polymeric latex coating and cured to integrally attach the cut resistant liner with the cured polymeric coating. When the latex glove is worn on a hand and a cutting edge, such as a knife edge, contacts the glove, a crease is formed due to slip at the tacky adhesive-cut resistant liner interface creating a geometry that reduces cut stress intensity at the knife-edge thereby increasing the cut resistance of the glove. Processes for making and using these gloves are also described.

The invention provides a communication resource motion processing method and a system. The method comprises the steps of obtaining resource information, obtaining a two-dimensional code template matched with the resource information from a preset two-dimensional code template base according to characteristics of the resource information, generating a two-dimensional graph according to the resource information and the two-dimensional code template, and controlling printing equipment to print the two-dimensional graph to obtain a two-dimensional label.

A magnetic recording head with reduced thermally induced protrusion. In one embodiment, a thermal expansion constraining layer comprising silicon dioxide for instance overlays a magnetic recording head. The thermal expansion constraining layer has a very low coefficient of thermal expansion. A sealant layer comprising aluminum oxide overlays the thermal expansion constraining layer. The thermal expansion constraining layer prevents deleterious deformation of underlying head structures that can degrade performance of a storage system. The sealant layer protects the thermal expansion constraining layer from propagation of surface defects therein by protection from shock, including shock during fabrication, as well as moisture, increasing manufacturing yield and reliability.

The invention discloses a method for setting a nuclear level indicator for a pressure vessel, which comprises the following steps of: 1) determining the mounting position of the nuclear level indicator on the pressure vessel according to an operation level in the pressure vessel; 2) according to the mounting position of the nuclear level indicator, determining the installation sequence of the nuclear level indicator as follows: a, the built-in nuclear source sleeve is installed; b, setting a nuclear emission source; c, surfacing the annular boss; d, a non-penetrating hole is machined; and e, installing a nuclear ray receiver.
