Patent GB-2176305-A (GB)
Title: Optical fibre isolator
Inventor: BRICHENO TERRY
IPC: G02F1/095
Filed: 1985-06-12
Abstract: Any linear birefringence included between the two linear polarisers of a classical Faraday isolator would be liable to introduce elliptical polarisation effects which would impair the degree of isolation obtained. In an optical fibre isolator the optical fibre is liable to possess residual stray linear birefringence, and this is augmented by strain-induced linear birefringence that results from winding the fibre into a coil. This linear birefringence can be swamped by a large effective circular birefringence effect produced by twisting the fibre. Normally this reduces, but does not eliminate, the impairment of isolation that is attributable to linear birefringence effects. Such impairment can however be eliminated if the effective circular birefringence is adjusted to provide substantially (n +/- 1/4) beat lengths.

Patent GB-930029-A (GB)
Abstract: 930,029. Electrostatic separation. METALLGESELLSCHAFT A.G. Nov. 30, 1961 [Dec. 9, 1960], No. 42922/61. Class 117. In a process for recovering residual solid carbonaceous fuel from ash and slag remaining after removal of reduced iron ore from the reaction mixture obtained upon reducing iron ore with solid carbonaceous fuel, the residual fuel, ash and slag particles are fed from a conduit f on to an earthed rotating drum W of electrically conductive material. The particles are subjected to an ionizing field d from an electrode i, to charge the particles. The particles then enter an earthed zone defined by the radii B, C, wherein the charge on the carbonaceous particles is reversed by contact with the drum surface. The ash and slag particles, however, do not suffer reversal of charge. As the particles pass into an electric field S generated from an electrode e, the carbonaceous particles are deflected away from the surface of the drum due to their charge and are collected. The slag and ash particles stick to the drum surface and are eventually removed by a brush b. The electrodes i and e are fed from the same high voltage source and the reduced iron is removed from the slag, ash and excess carbonaceous fuel mixture, prior to the electrostatic separation described above, first by screening and then by using magnetic separation.
