Today's 114° sweep, flattened faceplate picture tubes can reproduce images of extreme excellence in sweep linearity with considerably less energy spent, than has been commercially accepted in the past as ``high efficiency'' sweep, even with a relatively poorer linearity.

In 1958, Sylvania introduced a 5-tube 100 Ma. line of home radio tubes to aid in the reduction of heat from the original 150 Ma. ``All American Five''. Derived from the original 150 Ma. line, the new 5-tube complement featured more efficient cathodes to allow adequate performance from the 100 Ma. heaters. Sylvania now introduces a tube which combines two of the tubes from the 100 Ma. line into one envelope, providing a 4-tube string with performance capabilities similar to the 5-tube, 100 Ma. complement. This new tube, the Type 26HM8, is a triple-purpose tube serving as IF pentode, detector and 1st audio. The performance of the new 4-tube receiver is supplemented by the addition of a new improved power output tube, Type 40FR5.

This paper discusses recent experiments which demonstrate the feasibility of using transistor limiters at 4.5 and 10.7 mc. The circuits are fully described and the limiting performance discussed in detail. In the past transistors have sometimes shown poor performance as limiters because of a non-linear feedback effect between the collector and base of the transistor. The circuits that are to be presented are novel in that they include provisions for eliminating this effect. The circuits to be described are fully capable of meeting the design requirements of conventional vacuum tube limiters and as such permit the design of transistorized equipment which is fully competitive with vacuum tube equipment in this respect.

A pneumatic ultrasonic transmitter capable of generating a high-output 40 kc. tone burst has been developed and applied to a low-cost wire-less television remote control. Advantages over the more conventional transmitters, such as the struck gong or transistorized radiators, are economy, no batteries, higher output, durable construction, and ease of tuning. Because of the higher output, fewer and less expensive components are required in the receiver. Design parameters, circuit design, and operating results are discussed.

Adaptation of remote control to television is somewhat limited by the size of the remote control receiver. As the size of contemporary television sets decreases, space allocation becomes increasingly important.

There has been a long term trend in Television receivers toward larger and brighter pictures, with shorter picture tubes. This hag meant higher anode voltage and ever increasing deflection power for wider angle scanning. The tubes in the scanning circuits of TV Receivers are now required to handle peak currents and voltages that are commonly associated with much larger transmitting tubes. Consequently, the reliability of the tubes in deflection circuits has been a significant factor in the over-all reliability of TV receivers.

One of the principal problems involved in the design of a transistorized vertical deflection circuit is obtaining a linear deflection. Non-linearity errors are generated by the transfer characteristics of the driving network, the output transistor, and the output coupling network. The results of these non-linearity errors are cumulative and manifest themselves as deflection distortion.
