B62M 19/00
PCT/LV2012/000019MIROPOLECS, StanislavsMIROPOLECS, Stanislavs
The invention refers to hydraulic rotation transmission with two side output of driving shaft and one side output of driven shaft and can be used in power transmissions and transmissions where the stepless ratio variation is essential. It also can be used as stepless speed variation device in bicycles (Fig. 1). Getting any transmission ratio at reduced dimensions and mass is achieved in the hydraulic transmission by applying new scheme, including motionless and movable bodies containing two coupled rotors, composing of camshafts with pistons and separated by movable wall. Transmission ratio varies from 0 to maximal value displacing the movable body in axial direction by means of overhanging control arm.˙

The invention refers to hydraulic rotation transmissions and can be used in power transmissions and transmissions where the stepless ratio variation is essential. It can also be used as stepless speed transmission for vehicles (Fig. 1). Getting any transmission ratio with higher performance factor is achieved by applying in the hydraulic transmission new scheme, including motionless and movable bodies containing two coupled rotors, composing of camshafts with pistons and separated by movable wall. Transmission ratio varies from 0 to maximal value displacing the movable body in axial direction by means of overhanging control arm.˙

C09K 11/06
PCT/LV2012/000021DAUGAVPILS UNIVERSITĀTEKIRILOVS, Georgijs
A method for producing a novel luminescent polymer material has been developed, said method comprising copolymerizing two monomers (vinyl-carbazole and a benzathrone derivative), thereby producing an electrically conductive copolymer which is intensively luminescent in the red part of the spectrum from 595 nm to 650 nm, depending on the allyl-component content. This characteristic of the material produced can be considered an advantage thereof, since this provides the possibility of adjusting the optical properties of the copolymer depending on operational requirements. Said method relates to the field of materials technology and spectroscopy. Said method can be used for developing novel luminescent materials using a luminescent polymer produced on the basis of polyvinyl-carbazole, the presence of which ensures electrical conductivity. The copolymer produced can be used for developing novel flexible luminous materials, which can be used in electrophotography, for producing displays, light sources, sensors, diode lasers, and also in other fields requiring the provision of intensive red or orange luminescence, thereby converting electrical energy into light. For example, said copolymer is used in the construction of various electro-luminescent devices (OLEDs, monitors, etc.), since the production of OLED-containing light sources, displays and other devices is currently being intensively developed worldwide. Owing to the significant advantages of said devices - economy, flexibility, high degree of colour intensity and clarity, demand for said devices in these technologies continuously increases.
