Driven Anchor

A driven anchor is generally pounded into the soil to a design depth by repeated blows with a hammer. While this method is usually associated with pile anchors, it has been used to install plate anchors with the aid of a mandrel and follower.

Explosive Driven Anchor. Accdg to Goodyear Aerospace Corp of Akron, Ohio, 44315, expl driven anchors were proposed to be used to moor a very large balloon. Periodically die balloon must be moved and anchored with extreme rapidity with emphasis on anchoring the balloon securely in the shortest time possible. The expl driven anchor concept appears to be the most expeditious means for this task. The anchor must be capable of being driven into all types of soil and sustain a 1000 pound pull for a period of 48 hours. Fragmentation cannot be tolerated upon actuation of the expl charge...

BROWN et al.i95) have given data on the performance of 1.5 m diameter sulphonators and nitrators of 3.4 m3 capacity as used in the dyestuffs industry. The sulphonators were of cast iron and had a wall thickness of 25.4 mm the annular space in the jacket being also 25.4 mm. The agitator of the sulphonator was of the anchor type with a 127 mm clearance at the walls and was driven at 0.67 Hz. The nitrators were fitted with four-bladed propellers of 0.61 m diameter driven at 2 Hz. For cooling, the film coefficient hb for the inside of the vessel was given by ... 

Spontaneous reflection symmetry breaking in achiral LCs is also well known, driven by specific boundary conditions. A very simple example of this type of chiral domain formation is illustrated in Figure 8.11. Suppose we start with two uniaxial solid substrates, which provide strong azimuthal anchoring ...

The impeller is the part of the agitator that impacts force to the material being mixed. Propellers, turbines, gates, anchors, and paddles are all types of impellers. Typically, the impeller is a single propeller or turbine blade connected to a shaft that is driven by an electric motor at a fixed speed. There are two classes of impeller agitators axial-flow and radial-flow, and the mixing characteristics are shown in Figure 3.14. 

To install, the anchor is driven into the ground with a siedge hammer or a pneumatic tool. The explosive charge is pushed to the bottom of the anchor with a push rod and then exploded. A rapidly curing cement (grouting material) is then poured into the anchor ar H tamped to fill the camouflet enclosing the anchor tines (See Fig El)... 

These results were interpreted in terms of a substantial surface enrichment in Cu, driven by Cu s lower heat of sublimation [23]. The reactivity of these catalysts for CO oxidation, and the clear spectroscopic evidence for surface Pt - CO species indicate that, at least for the heterogeneous systems, particle surface stoichiometries are very sensitive to metal-adsorbate interactions. Similar arguments were presented for the PtAu/silica system, in which monometallic Au particles severely sinter under dendrimer removal conditions. In this case, the retention of small bimetallic particles after activation was attributed to the strength of Pt-silica interactions, which effectively anchored the bimetallic nanoparticles to the support [24],... 

The theoretical work of Ijawik was driven by the question to which position H moves to when added to complex aluminum hydride surfaces [85]. As intensively discussed for NaAlH4, without considering energetic or crystallographic issues, there are different sites at which Ti could anchor. It could first react with surface atoms and...
