In order to carry out the process, the installation for processing and recovering various polyester wastes comprises a briquetting system (4), a centrifugal milling chamber (11) and a discharge connection (14), consisting of a mobile or fixed cell (1), provided with a supplying vat (2) wherein the collected wastes are introduced by means of a flexible feeding system (3), namely by means of a secondary feeder (15), there having a chamber (5) for collecting briquettes (A) obtained by the briquetting system (4), which are taken over by a feeding system (6) mounted on a separating wall (B) of the cell (1), in order to be transported into an isothermal chamber (7), where, by means of an electronic device (8), there is determined the loading mass of the briquettes (A) as well as the regulation of the mass and pressure of the liquid nitrogen which penetrates into the isothermal chamber (7), by means of a feeding connection (10) from a storage tank (12) into the centrifugal milling chamber (11), where the briquettes (A) are crashed and comminuted depending on the wanted granulation, as well as a collector (13) where there is collected the resulting composition, which may be discharged through the discharge connection (14).

Title: Power circuit for electric locomotives having d.c. series motors
Inventor: MATU A REMUS GEORGE
IPC: B60L9/02
Filed: 2007-07-16
Abstract: The invention relates to a power circuit for electric locomotives having series D.C.motors. According to the invention, the power circuit consists of two adjacent motors (M1 and M2) to which there are serially connected some rotors (1 and 2) and with some excitation coils (12 and 13) forming some identical and independent power modules (A) for two axles, (A and B) for four axles, (A, B and C) for six axles, the field weakening being achieved continuously, by the decrease of the supply voltage of the excitation coils (12 and 13), by the control of some D.C.current voltage arms (14 and 15).
Patent RO-127561-B1 (RO)
Title: Intelligent microbarometer
Inventor: MOLDOVAN ADRIAN-SEPTIMIU
IPC: G01L13/06
Filed: 2010-11-25
Abstract: The invention relates to an intelligent microbarometer applied for monitoring and studying infrasonic fluctuations of the atmosphere, produced by natural and artificial events. According to the invention, the microbarometer comprises an electronic unit (A) equipped with a central processing unit (8) communicating with a GPS module (9) which offers information about the geographical coordinates at which the microbarometer is installed and pulses for the synchronization with the satellite clock, with a web server (10) ensuring the transmission of data in information networks under TCP/IP protocols and an analogue-digital conversion block (7) connected to an electro-pneumatic unit (B) equipped with a differential pressure transducer (3) which measures the difference of pressure between a pressure-supporting enclosure (1) equipped with a transducer (6) for electroacoustic calibration and an input enclosure (2) connected to the atmospheric pressure through an inlet port (5) and which intercommunicate through a microvalve (4).
