Patent DE-4116789-A1 (DE)
Inventor: DORN REIMUND DR RER NAT
IPC: G02F1/29
Filed: 1991-05-23
Abstract: An optical switch serves the purpose of relaying in a specific, selected direction a wavetrain irradiated onto it. Suitable as part of an optical switch is a light-transmitting material in which by applying an electrical field a three-dimensional diffraction structure is generated by means of which the direction of the wavetrain can be varied. An optical switch according to the invention has a material with optically nonlinear characteristics, in which the three-dimensional diffraction structure is stored. The material forms at least one single layer (2) which extends above a substrate (1). Electrodes (3 - 6) are present; the diffraction structure in the layer (2) can be varied by an electrical field which can be applied to the electrodes. A portion of the wavetrain irradiated onto the layer (2) is consequently deflected in accordance with the strength of the electrical field present between the electrodes (3 - 6). <IMAGE>

Title: Recycling moulded water-soluble resin - by spraying with hot water, centrifuging and drying soln. feeding product to extruder, pelletising product and reusing with fresh resin
Inventor: MAURO JAMES J
IPC: B29C33/76
Filed: 1991-07-17
Abstract: In recycling of water-soluble resin from an injection moulding, a water-soluble core is dissolved by a spray of hot water or a special solution, the resin suspension obtained concentrated, the residue is dried, and the dry resin is reduced and pelleted so that it can be mixed with fresh resin and re-used. The resin suspension is pref. concentrated by means of a centrifuge, and the product is dried by steam heating on a belt. The final material obtained is fed to an extruder where any residual moisture is completely evaporated off. The extrusion is pelleted. In the whole process each stage is conducted automatically by a control system with computer, so that each has it temp. sensors, flow meters and pressure sensors. The first stage uses deionised water and produces a 2-10 wt. % solution at 71.1-76.7 deg.C. This is pumped through a heat exchanger to reach 87.8-98.3 deg.C and is then sprayed on to the moulding core, followed by washing spray of deionisated water into the space where the core had been. ADVANTAGE - Enables resin for the so-called lost core moulding process to be recovered for re-use (typically an acrylic copolymer type). It recycles the resin without changing the physical or chemical properties of the resin. It reduces production costs as well as energy consumption and maintenance costs. It can be made more efficient by using part of the resin suspension to dissolve the core.
