Title: System for spatial isolation of optical noise sources
Inventor: CĂILEAN ALIN-MIHAI
IPC: H04B10/116
Filed: 2019-12-05
Abstract: The invention relates to a system for spatial isolation of optical noise sources, meant for applications of visible light communications (VLC), in exterior environment, at distances of tens up to hundreds of meters, especially in road VLC applications, such as road infrastructure to vehicle (I2V) communication and vehicle to vehicle (V2V) communication. According to the invention, the system is located in front of a VLC receiver and it consists of a sensor (1-SLS) for identifying the optical noise sources represented by a series of IR photodiodes (IrFD11...IrFD15 and IrFD21...IrFD25) with reduced receiving angle of up to 30°, an optical liquid crystal device (3-OLCD) and a data processing and control module (2-MPDC) which controls the obturation and spatial isolation of the optical noise source by controlling the polarization voltage applied to the liquid crystals of the optical device (3-OLCD), which results in the modification of the angle of rotation of the plane of polarized light passing through the liquid crystal, making the optical device (3-OLCD) become opaque in that area, while allowing the light to pass through the other regions thereof, thereby reducing the power of parasitic light incident on the photosensitive element of the VLC receiver and thus eliminating the possibility of saturation for the photosensitive element, the signal-to-noise ratio being improved, which leads to a maximization of the performance of the VLC receiver for the mentioned external context.

Title: Topologie generalisee d’onduleur multiniveau
Inventor: CHERKAOUI MOHAMED
IPC: H02M7/00
Filed: 2017-07-14
Abstract: Dans cette demande de brevet, une structure généralisée en cascade à haut rendement pour onduleur multi-niveaux est présentée. Cette structure asymétrique a l'avantage d'être compacte et compatible avec des sources de tension à ratio septénaire ce qui lui permet de générer un nombre important de niveaux avec moins de commutateurs de puissance. Vu aussi le nombre restreint des commutateurs actifs (unidirectionnels et bidirectionnels) par cycle d'opération, pilotés ainsi par une modulation de fréquence fondamentale dite nlc (nearest level control), un meilleur rendement en puissance est achevé (;::; 98% dans le cas de 49 niveaux). Par ailleurs, et afin d'inspecter la qualité des signaux de sortie, une réalisation de l'onduleur à 49 niveaux a été faite sans recours au filtre passe-bas. Les résultats obtenus montrent bien un meilleur profil harmonique et une conformité aux exigences de la norme en 50160 et aux codes ieee 1547 et iec 61727.

Title: Process and apparatus for field wrapping and preparing produce for market
IPC: A23B7/148
Filed: 1961-09-22
Abstract: A process for preparing edible produce grown in a field, using an apparatus moving across the field, includes the step of tightly encasing the produce in a plastics film immediately after gathering. The produce may also be cleaned, sprayed, blanched, graded, frozen or cooled and packed for shipment while on the mobile apparatus. The field vehicle 10 has lateral cantilever projections 13 which carry a number of wrapping tables 18 with heat sealing units 19 and seats 20 for operatives. Wheels 12 are adjustably spaced so that they ride in the furrows between the crop rows, and each operator collects produce from one row, wraps it in a plastic film, seals it and places it on a belt 15 which carries it through a heated shrink tunnel 28. An inclined conveyer 40 may carry the wrapped produce direct to a cartoning station, or, if the produce is to be cooled, to a freezing station supplied with liquid nitrogen. As shown in Fig. 7, the two oppositely moving belts 15 carry the wrapped produce to a lifting conveyer 52 and on to a conveyer 54, through a feed control chamber 56 which spaces the produce out and passes it through a gate lock 60 into an evacuated cooling or freezing chamber 51 supplied with liquid nitrogen through pipes 82. An open-mesh belt conveys the produce through the freezing chamber and through a gate lock to a take-off conveyer 59. The wrapping film used is gas and vapour permeable.
Patent ES-319003-A1 (ES)
Title: Optical method and devices for measuring positions,especially liquid levels
IPC: G01F23/292
Filed: 1965-10-28
Abstract: Apparatus for gauging the position of a movable object, for example a liquid level in a transparent tube, comprises means for projecting light on to a reflective curved surface movable bodily with the object, whereby the reflected light will envelop a caustic and form interference fringes adjacent said caustic, and a magnifying optical viewer for observing a selected one of said fringes. As shown, the viewer 7 and a light-source 15 are fixed on a rigid frame 16 which is displaceable parallel to a tube 2 containing a liquid 1, the level of which is under observation. Reflection of light from the source 18 at the curved meniscus 5 of the liquid sets up interference fringes which are observed through the viewer. A reticle wire in the viewer is brought into coincidence with a selected fringe by moving the viewer parallel to the tube 2. A comparator 11 supported on a fixed structure 3 which also mounts the tube 2 is coupled to the viewer 7 and adjusted to zero. Any subsequent variation in the liquid is recorded on the comparator 11 by moving the viewer until the same fringe coincides with the reticle wire. When an opaque liquid is under investigation the light-source 18 is arranged above the meniscus 5. In a further embodiment the light-source may be fixedly aligned with the tube 2 so that light strikes the meniscus in the same way regardless of the liquid level. In applying the apparatus to the measuring of displacement of a solid object a light weight element having a curved reflective surface, e. g. a glass rod, is attached to the object if such a surface is not provided by the object itself.

Title: Rotary grinding mill
IPC: B02C17/04
Filed: 1968-05-10
Abstract: A ball or tube mill containing loose grinding bodies includes a built-in dam ring 3, Fig. 1, constituting a partition between a grinding chamber 1 and a discharge chamber 2 that has an outlet for the ground material. The discharge chamber has means to return the grinding bodies to the grinding chamber through the dam ring. The discharge chamber has lifters 7 for the grinding bodies adjacent the outlet side of the dam ring, and the grinding bodies in falling off these lifters tend to pass back through the opening 8 in the ring 3. The dam ring may be provided with openings, and scoops 11 to lift the ground material and discharge it into a hollow trunnion 5. In a further embodiment, the opening in the dam ring may be surrounded by a frusto-conical ring and the chamber 2 may have a frustoconical lining and a suspended plate which with a screw-thread in the trunnion further assists return of the grinding bodies to the mill. Other embodiments include a triangular section ring around the opening in the dam ring 3, and a plate carrying a frusto-conical protrusion a mill with three discharge compartments and a conveyor screw in the trunnion a mill with three compartments with dam rings 3', 22', 23', Fig. 7, whose central openings successively increase in diameter and a mill in which the last chamber has a lining so that there is a reduction in internal peripheral speed of the chamber and hence in the consequent tendency for grinding bodies to leave the chamber at its outlet. In a further embodiment two spiral rings 29, 30, Fig. 10, each have a mouth 31, Fig. 9, at the periphery of the discharge chamber 2. As the mill rotates some grinding bodies pass through the mouth 31 and move along the tube to its curved end 32 and are thus returned to the preceding grinding chamber. Ground material passes over a frusto-conical lining 14, through openings 9 in a dam ring 4, to be picked up by scoops and delivered into an outlet trunnion 5.
