Abstract: A high pressure isostatic pressing food processing assembly (1a) has a vessel (2) with an internal chamber (21) closed at both ends with two head assemblies (3), each having a body (31) that includes a blocking chamber (32), a plug (35) disposed displaceably within the blocking chamber (32) and provided with a sealing means (351) apt to enter and sealingly close the internal chamber (21) during a pressure applying phase. The assembly (1a) includes at least two longitudinal tie-rods (4) juxtaposed around an external surface of the vessel (2), wherein each end of each tie rod (4) passes through a tie member (6), coupled with the vessel (2), and is coupled with a resisting surface (421, 43) transferring axial load on the tie member (6) at an axially external side of the end of the tie rod (4).

Abstract: A three-phase power supply (10), intended especially to supply LEDs system (20), has a system of a diode bridge rectifier which comprises rectifying diodes (101, 102, 103, 104, 105, 106). The three-phase power supply (10) is additionally equipped with FETs and each of the rectifying diodes is bypassed by an FET of a rectifying unit (111, 112, 113, 114, 115, 116), respectively, which is controlled by a control system (40), comprising an analog-to-digital converter ADC 403, a digital-to-analog converter (402), a microcontroller (401), which provides a control signal to a gate of the appropriate FET through the input/output (404). Once the control system (40), in particular the microcontroller (401), detects stable power supply conditions and starts operation of elements of an LED sequencer (30), it starts at the same time to control over the FETs in the active rectifier.
