Filed: 1989-02-09
Granted: 1994-04-19
Abstract: ABSTRACT OF THE DISCLOSURE             A cutting tool such as a tile saw is pivotally connected to a linear guide rod with a four-bar linkage.  The linkage allows the cutting tool to be raised and lowered over a work table to facilitate plunge cutting.  One link of the four-bar linkage is mounted over the linear guide rod in a fixed perpendicular relationship with the surface of the work table to ensure that the blade of the cutting tool is maintained in a similar perpendicular orientation throughout plunge cutting.  This is achieved by adjusting the links of the four-bar linkage as a parallelogram linkage.  A linear bearing is fitted between the fixed perpendicular link and the guide rod to allow the cutting tool and linkage to freely slide along an accurate linear cutting path.

Abstract: ABSTRACT OF THE DISCLOSURE             Process and Apparatus for the gas-phase polymerization of olefins in a fluidised-bed reactor The present invention relates to a process and apparatus for the gas-phase polymerisation of olefins in a fluidised-bed reactor maintained at a temperature T1.  A gaseous reaction mixture comprising the olefins to be polymerised passes through the reactor and is recycled to the reactor by means of a recycling line comprising successively a first heat transfer means, a compressor and a second heat transfer means.  The present invention consists in introducing a readily volatile liquid hydrocarbon into the inlet of the first heat transfer means or into the recycling line, upstream and in the vicinity of the first heat transfer means.  The first heat transfer means cools the gaseous reaction mixture to a temperature T2, below T1, while volatilising the readily volatile hydrocarbon and without condensing a constituent of the gaseous reaction mixture.  The second heat transfer means cools the gaseous reaction mixture to a temperature T3, below T2, for maintaining the fluidised-bed at the desired temperature T1.
