Title: An optical communication transmitter and receiver with misalignment measurement and correction
Inventor: DANIELE RAITERE
IPC: H04B10/112
Filed: 2021-06-28
Granted: 2023-01-02
Abstract: FSO systems rely on line-of-sight, and thus can be easily impaired due to disruptions such as atmospheric turbulence. There is a need for a more robust communication system allowing longer distances to be bridged and/or downtime to be reduced. 5 An optical transmitter is provided generating at least one optical alignment beam. The transmitter comprises at least one alignment modulator, to modulate the alignment beam with transmitter directional data. A suitable receiver may demodulate this information and use the directional data from the transmitter to simplify the attainment and/or maintenance of a sufficient degree of alignment. 10 Additionally or alternatively, the at least one alignment beam may be used to detect, characterize and/or monitor one or more environmental parameters. 15 (Fig. ZA)

Title: Method and apparatus for dehydrating a particulate material
Inventor: VARVAT PHILIPPE
IPC: F26B21/00
Filed: 1996-04-16
Abstract: The method and the apparatus are applicable for processing of waste products. The apparatus (10) comprises a channel (22) having an inlet end (38) for receiving particulate material to be dehydrated and an outlet end (36) for discharging the particulate material in a dehydrated condition. A screw cinveyor (30) rotably mounted in the channel (22) advances the particulate material while stirring the particulate material to enhance the release of water and noxious vapours. A fan (40) creates an air current in the channel (22) to entrain water and noxious vapours released by the particulate material. The vapours are directed toward a heating chamber (42) which incinerates dangerous and odoriferous compounds as much as possible. The resulting gaseous media is directed through a passage in a heat-exchange relationship with the channel (22) to elevate the temperature of the particulate material that is being processed and cause same to release water and noxious vapours. The passage is isolated from the channel to avoid direct contact between the burned gases that are released in the atmosphere with yet unburned gases aspirated from the channel. 9 claims, 5 figures

IPC: E02D7/12
Filed: 2011-11-24
Abstract: The invention relates to a hammer for ramming of piles on bottoms of oceans, seas, lakes and rivers, under the water. The hammer can ram piles in vertical or horizontal direction, as well as inclined piles at any angle against the vertical axis, with an increased speed. Moreover, the hammer is suitable for ramming of piles serving as anchors to which by means of ropes platforms for oil are fixed. The hammer includes a bumper (1) which moves on rails (2) from bottom to top and from top to bottom, by means of fixed to the bumper (1) rocket engines (4, 4a, 4b, 4d). The rocket engines can be chemical or catalyst. In the third option, the rocket engines can be electric, while the surrounding water is used as an operating body, regardless sweet or salty, and the source of energy for heating of the working body can be a laser. Thus, the hammer can operate under water without sealing and without necessity to operate in air or gaseous environment. This allows operation at any depth, including the deepest places in the ocean. The use of rocket engines for moving the bumper allows high speeds to hit, a significant energy of the impact and also a complex impact.
