Title: Robotic or remotely controlled flying platform
IPC: B64C27/20
Filed: 1988-02-13
Abstract: A flying platform (10), propelled by at least one ducted fan (11) causing a vertically downwardly directed airstream in and through a cylindrical duct (12). A vane system in the duct (12) has two mutually perpendicular pairs (31-34) of diametrically opposite first vanes, each extending in from the duct rim toward the center of the duct. Each pair of first vanes provides a pair of generally vertical walls parallel to a diametral line across the duct, and they define duct passages between the pairs of vanes and define quadrants between adjacent pairs. Each first vane has an upper, fixed, rigid portion and a variable camber flap (45, 46) depending therefrom. A first servomotor with linkages vary the camber of each pair of flaps (45, 46), so that the camber of the flaps (45, 46) of each pair is at all times the same amount but in opposite directions. Preferably, there are also four second vanes (41-44), one bisecting each quadrant, and a symmetric pair of spoilers (75-82) is mounted on each second vane (41-44). Each pair of spoilers (75-82) is independently movable, as a pair continuously between a position substantially blocking airflow through the outer portion of said quadrant and a position permitting substantially full airflow therethrough. A second servomotor with linkages symmetrically varies the position of its spoilers (75-82). There may be a radio receiver responsive to remote control signals for actuating each servomotor and its linkages.
Patent EP-0316021-A3 (EP)
Title: Doped and undoped single crystal multilayered structures
IPC: G02F1/03
Filed: 1985-04-10
Abstract: Disclosed is a multilayer electro-optical 
material having a plurality of adjacent, single crystals 
of varying electro-optical properties. This material 
is made by a method wherein the successive layers 
are epitaxially grown from a molten solution of said 
electro-optical material optionally containing at 
least one dopant.  
     In one embodiment, such electro-optic material 
comprises silver thiogallate, wherein successive epitaxial 
layers are grown from a molten solution of silver 
thiogallate and potassium chloride, and which optionally 
includes at least one dopant. This molten solution 
exhibits the characteristic that, for any specific 
solution composition, layers having different electro-­
optical properties can be obtained by cooling over the 
temperature range which will yield crystal growth of the 
composition corresponding to the desired electro-optical 
properties. By taking advantage of this temperature/­
composition phase precipitation, multi-layers are 
formed by cooling first within one temperature range 
to form on the seed crystal substrate a layer of silver 
thiogallate including the dopant and then subsequently 
forming on this first layer a second layer of different 
composition varying from substantially pure silver 
thiogallate to silver thiogallate including at least 
one dopant, by cooling within a different temperature 
range. By successively alternating between cooling 
over these different tempeature ranges, multiple 
layers are formed with adjacent layers having different 
electro-optical properties.  
     The multi-layered structures produced by the above 
method can be utilized in electro-optical devices, and 
particularly as the tunable birefringent medium in 
tunable electro-optic filters.

Title: Anti-bounce logic for critical loads
IPC: G06F11/00
Filed: 1989-06-13
Abstract: An anti-bounce system (10) for control of critical loads (22 or 
23) is provided. A control system contains two subsystems (41 & 42). 
The first subsystem (41) functions for normal control of the critical 
loads, but has a relatively long information processing time. This 
long time might prevent the system from controlling the loads in a 
safe manner. The system has a second subsystem (42) that has a very 
rapid processing time. Both of the subsystems are connected to the
