Title: Work-generating engine with no energy consumption
Inventor: ZAFEIROPOULOS GRIGORIOS PANAGIOTI
IPC: F03B17/04
Filed: 2012-11-20
Abstract: The invention allows the construction of an engine having for basic mechanism one parabolic caterpillar which is vertically-positioned into a water tank and composed of tight chambers 1 the volume of which are -upon compulsory driving and synergy of adequately-positioned magnets- increased or decreased at points and time dictated by the construction of the engine. The operation of the engine is based on the buoyancy property of liquids. The chambers of the upper section of the arrangement are compressed and air is, thus, propelled to the bottom chambers which are inflated so that the difference of volume in the chambers of the two rectilinear sections of the caterpillar can cause the buoyancy of the side containing the greatest air volume and creating, thus, a non-stop motion. At each chamber 1, there are adapted accessories (34,35) which, being meshed on the rectilinear section of the caterpillar via the toothed gears (36,36a), are able to convert the rectilinear motion of the chambers into rotary so that measurable work can be incessantly produced.

Title: Turbo chimney's heating system
Inventor: ROUTIS EFTHYMIOS MELETIOU
IPC: F24B1/188
Filed: 2013-01-31
Abstract: The invented chimney’s turbo heating system is supplied, via the motor 2 encountered at the external part of the house, with environmental clean air the inlet quantity of which is controlled by a dimmer 1 connected to the motor. After being initially heated up, the inlet air is drawn through the tube 3 to a collector/separator and, in the sequel, through the tubes 5, to a second collector 6 wherein two diaphragms and five through tubes 9 are placed. This collector can vary in respect to the type of the chimney in use. After additional heating of the air, this last is received by 8 tubes 10 and conveyed to the final collector 11 found at the base of the fire place. After final air heating, the hot air passes through the two apertures 12 for being finally released in the space through the tubes 13. The air conveyance to the entire house space is effected in a natural and original manner by removing the cool air from the rooms via ventilators 14 and leaving passage to the hot air to fill up the room’s space. The invention offers efficient heating, sufficient ventilation of the space with non-recycled new hot air, and maximum economy since the quantity of combustion material needed for the complete heating of a house equals that used by an ordinary chimney.

Abstract: Transmission of control data by a user equipment (UE) in circumstances following a TDD subframe reconfiguration from an evolved node B (eNB) may result in a conflict with a scheduled transmission of the control data. In one example a UE may modify periodicity content priority or other aspects of channel state information (CSI) or sounding reference signals (SRS) to resolve any conflicts resulting from a TDD subframe reconfiguration and to ensure transmission of the CSI or SRS. In another example a UE may detect a hybrid automatic repeat request (HARQ) conflict resulting from a TDD subframe reconfiguration. In such example the UE may determine and apply a HARQ soft buffer size for a HARQ process or determine and apply a codebook size for a HARQ process in carrier aggregation to resolve such HARQ conflict.

Abstract: A conventional cord having bulges is provided with an elastic rubber core and exhibits a difference in elongation or contraction between the rubber part corresponding to the end of each bulge and the rubber part corresponding to the center thereof. Namely, a part which undergoes severe elongation and contraction and a part which does not undergo elongation or contraction coexist in the elastic core. Therefore, a high strain is accumulated in the boundary region between both parts, so that the core results in rupture when the strain reaches a limit. Such a conventional cord is disadvantageous in that a relatively weak material such as rubber is unavoidably subjected to operation causative of strain accumulation. The present invention is a cord provided with a tubular cord body that is made of a stretchable material and that has bulges which are repeatedly arranged with spaces thereamong and the diameters of which change in dependence on the axial tension applied to the cord body.
