Abstract

The object of the invention is to provide a kit for measuring the permittivity spectrum of bulk and liquid materials, characterized in that it comprises a multi-rod reference probe (1A) consisting of a signal rod (2A) located in the central part of the probe (1A), and ground rods (3A) arranged at equal angular intervals around the signal rod (2A), and a multi-rod target probe (IB) consisting of a signal rod (2B) located in the central part of the probe (IB), and ground rods (3B) arranged at equal angular intervals around the signal rod (2B), and a primary calibration system and a secondary calibration system and a control unit (6), wherein the probes (1A, IB) are connected by a microwave connector (5) to a vector circuit analyzer (4) that is connected to the control unit (6). The object of the invention is also to provide a method for calibrating the multi-rod probe included in this kit.

Abstract

An asphalt binder foaming device, having a heated tank casing (1) with a drain (1.1) in the lower part, while on the upper surface of the tank casing (1) there is a cover (2) having an asphalt inlet (2.1) and an exhaust spigot (2.2). Inside the tank casing (1) in the vertical direction there is a drive shaft (3) connected to a drive, wherein mixing blades (3.1, 3.2) are mounted to the drive shaft (3), characterised in that the drive shaft (3) has in its axis a blind opening (3.3) open from the top, with a wall in its lower part, wherein a foaming material injection device is connected to the open end of the blind opening (3.3). In the wall of the drive shaft (3) there are through openings (3.4) between the blind opening (3.3) and the outer surface, while on the drive shaft (3), a sleeve (4), in whose wall there are through openings (4.1), is mounted in a nonrotary and nonsliding manner at the height of the through openings (3.4), or the through openings (3.4) of the drive shaft (3) and the through openings (4.1) of the sleeve (4) are at the same height.

Abstract

The invention provides a system, in which the temperature measurement modules (T1 and T2) are connected to the inverter (i) via the control module (CM), and the direct current buses (DC) are connected to the inverter (i). On the other hand, the inverter (i) is connected to the compressor (CO), which is connected via two lines to the connector (a) and (b) of the four-way valve (4WV). Also, the four-way valve (4WV) is connected to the connector (c) with the condenser-evaporator (C/E), which is connected in parallel to two expansion valves (EV1 and EV2). On the other hand, the expansion valves are connected in an inverse-parallel configuration to each other. Also, the expansion valves (EV1 and EV2) are connected to the connector (2) of the plate exchanger (PE), wherein the plate exchanger (PE) is connected via the connector (1 ) to the connector (d) of the four-way valve (4WV). On the other hand, the connector (3) of the plate exchanger (PE) is connected to the heat exchanger (HE) and to the controlled valve (CV3). Also, the heat exchanger (HE) is connected via the controlled valve (CV1 ) and the controlled valve (CV2) to the heat and cold storage unit (CS), which is connected to the circulation pump (CP). On the other hand, the circulation pump (CP) is connected to the connector (4) of the plate exchanger (PE). And the controlled valve (CV3) is connected between the controlled valve (CV1 ) and the controlled valve (CV2), whereas the controlled valve (CV3) is connected via the controlled valve (CV4) in-between the heat and cold storage unit (CS) and the circulation pump (CP).
