Abstract: ABSTRACT            A catalytically active powder, its preparation, and a method for using the said powder for making insulating substrates activated to receive electrolessly deposited metal in a coherent metal layer are described.  It is a plastic powder containing chemical compounds allowing that the acceleration of the catalyst is not carried out until the powder is melted down onto the substrate.  The substrate need not be etched prior to the metallizing since the plastic melted down ensures a good adhesion between metal and plastics and between plastics and substrate.  Furthermore, the colloidal nature of the catalyzing compounds has in a particular and especially durable manner been stabilized by the plastic powder.  The use of the powder causes less risk to the environment since the catalyst may be transported as a dry powder, and since the etching of the substrate is avoided.

Abstract: "A METHOD OF AND APPARATUS FOR APPLYING A STRUCTURAL LINING TO A PIPE"                     ABSTRACT OF THE DISCLOSURE           A spraying device is drawn through an underground pipe, and sprays a thixotropic resin onto the inner walls of the pipe.  The resin cures and hardens, to form an internal lining to the pipe.  The resin has sufficient thixotropy to enable it to be applied in a single operation to a significant thickness, preferably in the range 2 to 25 mm. The lining which is formed upon curing therefore has significant structural strength.  To allow such a resin to be pumped from the surface down to the spraying device, along a significant length of tubing, the resin is firstly heated, prior to being pumped.  Also disclosed is a swab for swabbing a pipe immediately prior to the application of a lining therein.
