Title: Optical pick=up for disc systems - has reflected signals separated into polarised components for precise track control
Inventor: AJIKI SEIICHI
IPC: G11B11/105
Filed: 1990-12-21
Abstract: A laser (1) generates an output that is transmitted through a collimator lens (2), halfwave plate (3) and a beam splitter (4) to allow the beam to be focussed (5) onto the disc (15).  The signals reflected back fromt he disc are directed by the beam splitter through a halfwave plate onto a second splitter (7).

Title: CRT disposal - uses a wash reactor for ground glass and metal and plastics, with medium to dissolve glass coating
Inventor: BAHNEMANN MANFRED
IPC: H01J9/52
Filed: 1992-12-17
Abstract: For the disposal of CRTs, at least the glass and also if required the metal and plastics components are granulated and ground.
