WO/2016/161489 METHOD AND SYSTEM FOR LAYER-WISE GENERATION OF THREE-DIMENSIONAL MODELS FROM POWDERED MATERIAL||WO||13.10.2016|
||PCT/BG2016/000010||"PRINT CAST" LTD||TODOROV, Georgi, Dimitrov|
The method and system for layer-wise generation of three-dimensional objects from powdered material includes sequential application of powdered material and suitable binder onto a vertically mobile worktop (2). Depositing is performed by a powdered material application device (1) and a binder application device (3). The two application devices (1 and 3) work in two mutually perpendicular directions along two horizontal planes parallel to each other and the worktop (2), performing the application in both directions of movement between their final positions. Application devices (1 and 3) move and deposit the respective substance at a different optimal rate depending on the process. The method and the system have a wide range of applications in the casting industry for the layer-wise generation of complete sand molds and/or high precision cores directly from a three-dimensional computer model. They reduce the time required to produce casting shapes and improve the accuracy, and also allow the generation of more complex shapes without the need for a physical model.
WO/2016/154688 RESILIENT CUSHIONING RAIL FASTENING WITH HORIZONTAL ELASTICITY IN THE TRANSVERSE DIRECTION FOR SMALL-RADIUS CURVES||WO||06.10.2016|
||PCT/BG2016/000013||"DENDRIT" OOD||BAHAROV, Georgi Stefanov|
A resilient cushioning rail fastening consists of a cast iron baseplate (3) on a wooden sleeper (2). The baseplate has through openings which pass through supporting cones on the underside thereof, said supporting cones being fitted into dimensionally corresponding recesses in the sleeper (2). Steel screws (5) pass through the openings, are screwed into plastic dowels (6) incorporated into the sleeper (2), and clamp the rail (1) via two resilient clips (7). The iron baseplate (3) has two flanges (10) and (11). The outer flange (10) is provided with recesses, into which are inserted helical/disc/shaped springs (9) that press the foot of the rail (1) against flange (11). A strictly defined gap (a) is formed. When rolling stock enters a curve, transverse horizontal forces, overcoming the force of the springs (9), displace the foot (1) until the latter rests against the rigid support (10).

WO/2016/115610 REFLECTOR SYSTEM AND A CONVEX MIRROR METHOD FOR SOLAR AND PV SYSTEMS||WO||28.07.2016|
||PCT/BG2016/000002||MITEV, Gancho||MITEV, Gancho|
The invention relates to the field of "Batteries: thermoelectric and photovoltaic with concentrators, orientators, reflectors". It turns out to be a combination of existing up-to-date components. The Reflector system invented is not a concentrator. It comprises one or more diffusing (convex) mirrors mounted at an angle above solar (thermal) or PV panels. It illuminates the panels additionally with direct sunlight while the sun is low above the horizon. And when it rises, the system radiates them with reflected diffuse-scattered in the atmosphere light only. The Reflector system does not cause any overheating and aging of the panels. It increases their production in periods when they operate at a capacity lower than half of their capacity. The Reflector system uses diffusing (convex) point-focused or line- focused reflectors. Such mirrors have the shape and position ensuring that only within periods after sunrise, prior to sunset and in winter time- only when the sun is low above the horizon, they diffuse the direct sunlight falling on them to the photovoltaic or thermal modules. While, during the rest of the time they reflect the diffused-scattered light.
WO/2016/112443 METHOD AND TOOL FOR MACHINING CYLINDRICAL HOLES||WO||21.07.2016|
||PCT/BG2015/000003||GD INZHENERING EOOD||MAKSIMOV, Yordan|
The invention can be used in machining cylindrical holes in metal structural elements which are subject to cyclical external effects. The present method includes mounting a workpiece and carrying out plastic deformation using a tool (100) which is inserted into the hole to be machined (8) and moved in the direction of the axis thereof such that the working portion of the tool passes completely through the hole and is then withdrawn therefrom. What is characteristic is that the workpiece (4) is mounted by means of clamping same with a clamping force F between two supports (1) and (5), one or both of which are moveable and each of which is provided with a hole (45) which is larger than the hole to be machined (8). The tool is characterized in that it is provided with a resilient deforming element (27), which is compressed as the tool (100) is withdrawn in a direction opposite to the direction of insertion. The main advantages include an increase in the fatigue life of a machined structural element and a reduction in the axial force required for reverse movement.

The invention refers to a generator with permanent magnets which has a magnetic field rotating externally relative to the axis of the rotation and which, to a limited extent, produces electrical energy in the form of alternating current for domestic and industrial needs. The main feature of the generator is that a single magnetic field passes through a coil, which remains stationary, and that with a series of permanent magnets generating this magnetic field by being specifically positioned on an aluminum ring intersect the coil, attached to a stator, producing, in this way, electrical energy.
