Patent number: 7461648Abstract: Apparatus for forming a multiplicity of thin wafers from at least two similar blocks, the apparatus comprising a supply reel (1) to supply wire, an upper pair (3a, 3b) and a lower pair (3c, 3d) of parallel spaced roller guides and a collection reel (4); a wire from the supply reel passes around successive grooves along the roller guides from near the supply reel to near the collection reel, so to form a four sided continuous web of wires along the length of the roller guides. Part way along the roller guides, the wire is diverted around at least two pulley wheels(5a, 5b) removing the wire from the web after it has passed over a roller guide at a predetermined point, and reintroducing the wire into the web via a subsequent roller guide at a point laterally displaced from the point at which it left the web, so that there is a gap in the web of wire which divides the web into two separate sections, and no cutting action can occur in that gap.Type: GrantFiled: May 12, 2005Date of Patent: December 9, 2008Assignee: Rec Scanwafer ASInventor: David Ainsworth Hukin

Publication number: 20040237535Abstract: A micro turbine (10) has a recuperator (20). During startup, an alternator (26) acts as a motor to turn the turbine rotor (32) and compressor rotor (34) of gas turbine (40). The speed of the gas turbine (40) and a fuel control valve (42) are controlled in order to prevent the rate of change of temperature at a gas turbine exhaust sensor (74) and/or a recuperator sensor (80) from exceeding a predetermined value in order to reduce thermal shock on the recuperator during startup. Controlled shutdown sequences are also provided.Type: ApplicationFiled: July 9, 2004Publication date: December 2, 2004Inventor: David Ainsworth
