Abstract: It is an object of the present invention to provide a soil-stabilizing agent with less emission of dust, good reactivity, good behavior at mixing and good dispersibility and a method for soil stabilizing treatment capable of restraining the emission of dust in the procedure of sprinkling and mixing of the soil-stabilizing agent to soil. 
     The soil-stabilizing agent according to the present invention comprises a mixture of a material mainly composed of quick lime and/or calcined dolomite and fibrillatable polytetrafluoroethylene resin. 
     And the method for soil-stabilizing treatment according to the present invention comprises the following steps; adding a mixture of a material mainly composed of quick lime and/or calcined dolomite and fibrillatable polytetrafluoroethylene resin to soil, and mixing them under the hydration heat generated by the reaction between the quick lime and/or calcined dolomite with moisture in the soil to form hydrated material. 
     When PTFE is in partially fibrillated state, emission of dust while sprinkling (primary dust) from the soil-stabilizing agent will be restrained as the particles of quick lime and/or calcined dolomite are enclosed in a cobweb-like net of the partially fibrillated PTFE, and emission of dust while mixing (secondary dust) is further restrained by a cobweb-like net of PTFE fibrillated further by mixing under hydration heat generated by the reaction of quick lime and/or calcined dolomite with moisture in the soil.

Abstract: Since the trend in integrated circuit technology is to increasingly finer structures, it is necessary to adapt the crossings to these miniaturised circuits. In addition, the air-gap-isolated crossings should be mechanically stable. A manufacturing process and an air-gap-isolated crossing is provided which are suitable for producing fine structures. A ceramic substrate having conductor tracks is coated with copper into which holes are etched above the contact points on the conductor tracks. The contact points and the copper situated in between are reinforced by electroplating with gold. In this way, the crossing is produced by means of a mask process with two-fold exposure. As a result of etching away the copper, air is left as the dielectric. Lange couplers, fine structures for planar circuits.

Abstract: The invention provides a flexible packaging sheet including at least three layers and being suited for wrapping, packaging and shipping food articles that are to be heated in a microwave oven. The laminate has inner and outer layers of flexible material and a layer of microwave interactive coupling material interposed between the inner and outer layers. A porosity differential exists between the inner and outer layers, the inner layers being relatively gas and vapor impervious, and the outer layer being relatively porous for venting and thus eliminating volatile fumes, smoke, vapor or gas produced within the laminate during heating of the food. In this way such fumes, smoke, vapor or gas is removed and contact between it and the food is prevented.

Abstract: A breakstem rivet installation tool includes a jaw mechanism (12) for gripping the stem of a rivet, and a pneumatically actuated piston and cylinder device (13) for applying pulling force to the jaw mechanism. It is provided with a damping valve (22) for damping the flow of air from the piston and cylinder device (13) when the force is suddenly released on breaking of a rivet stem (23), thereby to reduce mechanical shock to the tool, and noise of fast-escaping air. The damping valve (22) comprises a resilient steel circular disc (32) which is secured at its centre to the apex of a domed member (28) provided with vent holes (26). The undeformed shape of the disc (32) is flat. When, in use of the tool, a rivet stem breaks and the restraining force on the piston (15) is released, the velocity of air flow past the disc (32) urges the disc to bend towards the domed surface of the member (28), thereby restricting the air flow through the vents (26). It may be that the valve closes completely, so that the peripheral edge (36) of the disc (32) contacts the annular valve seat (37) surrounding the air vents (26).
