Title: Single mode fiber optic single sideband modulator
IPC: G02F1/33
Filed: 1984-11-20
Abstract: A fiber optic frequency shifter includes an optical fiber (24) having two modes of propagation, each with a different propagation velocity, and a coupler for applying time varying stress to the fiber at first and second locations on the fiber, with a predetermined phase relationship between the stress at the two locations. The coupler may include a plurality of discrete coupling elements, such as ridges (84, 86) or driving electrodes (163, 164, 165, 166) and a driver to drive the coupling elements in accordance with driving signals having the predetermined phase difference, or the coupler may include an acoustic wave generator (118, 120, 122) coupled to the fiber (114) for applying to the fiber an actual travelling acoustic wave. With the discrete distributed coupling elements, the frequency of the driving signals and the phase relationship between the driving signals is such as to create a simulated travelling acoustic wave in the fiber (24). The real or apparent travelling acoustic wave in the fiber causes light propagating through the fiber to be coupled from one of the fiber modes to another of the fiber modes, and to cause the coupled light to be frequency shifted relative to the initial light. The wavelength of the real or apparent acoustic wave is approximately equal to an integer multiple of the fiber beat length to cause constructive coupling of the frequency shifted light.

Title: A structure of modular elements for protecting the edges of canals, ditches and watercourses in general
IPC: E02B3/12
Filed: 1984-09-06
Abstract: The subject of the present invention is a structure of modular elements for the protection of the edges of canals, ditches and water courses in general, characterised by the fact that it comprises a plurality of slab-like modular elements, preferably made of cast concrete with steel reinforcements. These slab-like elements have a square conformation with a square aperture in their central portion. The upper faces of the slab-like elements have a slightly frusto-pyramid shape, converging towards an aperture, in such a way as to define a plurality of adjacently disposed trapezoidal projections on the major face. On two opposite edges of the slab-like modular elements there are eyelets, which advantageously are directly formed by the reinforcing steel. The modular elements (1) are disposed adjacent one another in such a way as to create a cover over the bank (10) of the water course, beneath which can be preliminarily provided a suitable ballast. The modular elements are joined together by longitudinal connection wires.
Patent EP-0157227-A3 (EP)
IPC: G01C3/06
Filed: 1985-03-09
Abstract: An interferometer apparatus is disclosed for determining 
the spatial relationship of two or more observed points (26, 28) 
such as the height of a magnetic transducer as it moves over 
the surface of a spinning recording disc. A light beam having 
two components of characteristic polarization and frequency 
is separated with one component being directed upon the two 
observation points (26, 28) one of which may be on the trans­
ducer head and the other may be on the spinning disc. The 
other component is simultaneously directed upon a reference 
surface (32). The reflected beams are then combined to pro­
duce an optical beat frequency which is subsequently de­
tected electronically and converted to a voltage representative 
of the phase shift between images of the two points and uti­
lized to provide the display of the distance between the two 
points.

Abstract: A diverter 5 for a conveyor installation (1, 2, 7), especially 
suitable for articles with a deformable undersurface, such as 
freshly baked bread 4, is in the form of a slide 15 with a first 
set of narrow parallel slide rails 18, (usually four) with 
coplanar upper edges and a second such set, at an acute 
diversion angle thereto, movable to present its slide rails 19 
above the plane of the upper edges of the first set so as to 
intercept a desired article 4 or sequence of articles e.g. for 
diversion to a slice-and-wrap machine.  
     Surprisingly, the subsequent orientation of the articles 4 is 
unchanged whichever set of slide rails is used, so that for 
example loaves of bread 4 are presented to either of two 
diverted paths 2, 7 without alteration of orientation so as to 
facilitate subsequent treatment.

Title: Spraying apparatus
IPC: B05B3/18
Filed: 1985-12-05
Abstract: An apparatus for spraying liquids from a vehicle, suitably an aircraft or other airborne vehicle. The apparatus includes at least two sprayheads, each having adjacent thereto an associated electrode or an associated electrically conducting or semiconducting part of the vehicle. Generator means apply potentials to the sprayheads and to the electrodes or conducting or semiconducting parts of the vehicle so that an intense electrical field is developed between the liquid which emerges from each sprayhead and the adjacent electrode or part. The intensity of each field is sufficient to atomise the emerging liquid. The polarities of the applied potentials are such that liquid emerging from one sprayhead is charged positively whilst liquid emerging from the other sprayhead is charged negatively. Connections to the generating means are such that electrical current flows from a target to the generating means via spraying liquid and one of the sprayheads and then back to the target via the generating means, the other sprayhead and liquid emerging from the other sprayhead.
