Abstract

1367022 Cathode-ray tubes; travelling wave tubes TEKTRONIX Inc 4 Jan 1972 [24 Feb 1971] 38331/73 Divided out of 1367021 Heading H1D The disclosure is substantially identical to that of application (Specification 1,367,021) but the claims are directed to the provision of compensating plates (56, 58) which overlie the helices of a delay line type deflection system.
