The present invention relates to an apparatus for gas phase polymerisation of olefins(s), essentially comprising a fluidized bed reactor and at least one conduit for drawing off polymer provided with an isolation valve and connecting the vertical side wall of the reactor to a lock hopper, the said conduit leaving the vertical side wall of the reactor while being directed downwards so that each par...

The present invention relates to a process for continuous gas-phase polymerization of olefin(s) in a fluidized and/or mechanically stirred bed reactor, comprising a stage of drawing off the polymer out of the reactor, wherein a portion of the bed is transferred into a lock hopper and is then isolated from the reactor in the lock hopper for a period of 5 to 120 seconds so that a substantial amount ...

To package large scale semiconductor wafers (101) a packaging device (103) is provided which engages the wafers (101) e.g. by supporting members (105A, 105B) and hence supports the wafers (101) in a spaced-apart stack. Preferably, the supporting members (105A, 105B) include means for making electrical contact between the device (103) and the wafers (101). The device (103) may be in the form of a p...

A ceramic fibre reinforced metal rotor with integral rotor blades is manufactured using a continuous strip of unidirectional ceramic fibres in a metal matrix. The continuous strip of ceramic fibres in the metal matrix is cut into a plurality of separate pieces of predetermined length. The separate pieces of ceramic fibres in the metal matrix are arranged alternately in a spiral, with separate piec...

The process involves two stages. In the first, a stabilised grouting is prepared by mixing cement, water and a stabilising agent which stops the hydration of the cement. In the second stage the grouting is injected into the sleeve without any water which may have exuded from it. Any exuded water may be removed by placing a sheet (3) of absorbent material on the upper surface of the stabilised grou...

The pallet (1) has an upper part (2) in corrugated cardboard with cross-shaped undulations. It has a lower part (3) in corrugated cardboard, and cardboard feet between the upper and lower parts. The feet are made from cardboard rolled and glued to form tubes, and are fixed on the upper and lower parts of the pallet. The lateral feet (4) are flattened and arranged so that the largest side of the f...
