Title: Improved display device
IPC: G09F11/32
Filed: 1988-04-06
Abstract: Display device comprising shaped guide plates (44) positively guiding the suspension rods (4) of viewing sheets (3) around a roller (8) when each suspension rod (4) is engaged by cradles (11) carried by electrically driven chains (10). A strap (50) which is rendered resilient by the inclusion therein of a spring (53) extends centrally down the rear of the device and prevents the successive suspension rods (4) from becoming detached from the cradles (11) in this region. A gate which includes a stop (55) is provided at the foot of ramps (5) upon which the rods (4) are stacked to ensure that the rods will not become bunched or otherwise entangled on the ramps (5) and that the cradles (11) will positively pick up only one suspension rod (4) at each passage past the gate. A time delay switch (56) is associated with a microswitch (41) and will close to bypass switch (41), after a predetemined interval of time, so that the drive of the device may re-start even if the power supply to the device had previously been switched off with the microswitch (41) in its open circuit position. Each rectangular display sheet (3) preferably comprises two layers which are secured to one another at the edges which coincide with the suspension rods (4) and along one of two longitudinal edges. The other edge is open except for two relatively short portions that are joined together at its opposite ends, whereby webs carrying indicia may be entered between the layers, by appropriate flexing, and will remain trapped therebetween by the short joined together edge portions of the two layers.

Patent EP-0318148-A3 (EP)
IPC: G03H1/02
Filed: 1988-10-14
Abstract: The recording of static holograms such as are used for the storing of 
digital data is enhanced by the application of a low frequency 
electrical field along the 110 axis 
of a photorefractive crystal (10) when 
the relative beam intensities are maintained within limits. The best 
enhancement is found in the region of 100 Hertz and the effective band 
width is very narrow. The enhancement decreases with divergence of the 
beam intensities from equality and incurs the cost of increased 
amplitude, effectively vanishing by the time an intensity ration of 
1000′1 is reached. Counterpart apparatus is provided.
