Title: Bottom discharge device
IPC: B65D90/62
Filed: 1979-09-19
Abstract: Bottom discharge device (2), especially for vehicles (1), which preferably are intended to transport dry fine-grained material. In known vehicles of this kind problems arise by leakage of the transported material through the discharge doors. The material being finely distributed and dry, dust is formed which is very inconvenient from several aspects. The present invention has the object to produce a bottom discharge device (2) where leakage of material has been eliminated. This is achieved in that the bottom discharge doors (9) from above abut the edges of the discharge opening. The edges of the discharge opening preferably are provided with sealing strips (17a, 17b), against which the edges of the doors sealingly abut. The transported material pressing down the doors against the edges of the opening, the device is self-sealing.

Title: Liquid Crystal Displays
IPC: G09F9/00
Filed: 1980-09-03
Abstract: Viewing of a liquid crystal display cell, e.g. in an aircraft cockpit, is facilitated by securing a partially transmissive, partially reflective diffuser 24, formed for example of opal glass, to the rear surface of the liquid crystal display cell 12 so that the diffuser is disposed between the liquid crystal display cell and a micro- corner cube retroreflector 26. Scattered light transmitted by the diffuser is reflected by the micro- corner cube retroreflector back to the diffuser along the same paths as the light emerged from the diffuser, causing the reflected light to be scattered through the liquid crystal display cell within a wide viewing cone centered about the direction of the light ray incident on the liquid crystal display cell. In this way, maximum use is made of the ambient light to achieve a display with increased brightness. An index matching layer 28 may be provided between diffuser 24 and reflector 26, and the latter may include a reflective layer 29 to increase the angle over which each corner cube can reflect light. <IMAGE>
