Abstract: A time base corrector converts an analog input PAL image signal including a certain time base error into digital form and then stores it in a memory (13) by using a write clock signal derived from the input PAL image signal including the time base error. The stored signal is read out from the memory (13) by a reference readout clock signal to eliminate the time base error, and a reference colour burst signal is added to it in an adder (22). The time base corrector extracts a colour subcarrier signal (Cʹ) from the input PAL image signal by means of a low pass filter (2), samples the colour subcarrier signal by using a first clock signal (CK) in a manner such that U-axis data and V-axis data of the colour subcarrier signal are generated independently of each other, compares by means of an exclusive -OR gate (19) the polarity of the V-axis data of the colour burst of the sampled colour subcarrier signal with the polarity of the V-axis data of the reference colour burst signal, and selectively inverts in a V-axis inverting circuit (18) the polarity of the V-axis data of the colour burst of the sampled colour subcarrier signal on the basis of the comparison result.

Abstract: The rotary outlet valve for an outlet opening of a product vessel includes a valve body (20) having a bore formed therethrough along a central axis (22) to provide a central flow path (23) for product through the valve body (20). A valve seat assembly (40) is attached to the valve body (20) and circumscribes one end of the bore, with the assembly (40) having an upper surface (41) designed to be close coupled to an outlet opening of a vessel, and inclu­ding a valve seat member (42). A valve closure member (50) is rotatably mounted within the valve body (20) for rota­tion between open and closed positions. The closure member (50) includes a top sealing surface (51) designed to seal­ingly interact with the seat member (42) of the valve seat assembly (40) when the closure member (50) is in closed po­sition, and a pair of oppositely disposed, spaced support members (52,53) depending from the under-portions of the sealing surface (51) for rotatably mounting the closure member (50) within the valve body (20). A shaft (70) which is rotatable about a rotating axis (71) provides rotational movement to the closure member (50). In particular, the shaft (70) is attached to at least one of the spaced sup­port members (52,53) within the valve body (20) along the rotation axis (71) and adjacent the periphery of the bore such that when the closure member (50) is rotated to open position within the valve body (20), the shaft (70) and the attached closure member (50) are located substantially radially outside of the central product flow path (23). In this way, unobstructed product flow is permitted along the flow path (23) through the bore.
