Abstract: A heat exchanger or boiler has a bypass between the inlet and the outlet. The outlet includes a chamber having a partition with a thermostatically controlled valve, which controls flow of heating medium from the heat exchanger to the outlet connection. The thermostat maintains the temperature at the chamber. The bypass is from an inlet chamber to the space beyond the thermostat. The thermostatic valve, itself, is of a typical known construction consisting of a valve member actuated relative to a port in a plate by means of a thermostatic element axially positioned relative to the valve member. The plate forms part of a partition formed in a header member which forms a chamber at the outlet of the heat exchanger from which the heating medium flows through the thermostatic valve, to the outlet conduit. The bypass is controlled by a plate partially obstructing a passageway and it may be flexible to respond to flow of medium to have a throttling effect.

In the exemplary body of said adaptation the note from the instrument is picked up through a microphone and fed through electronic means for isolating the fundamental frequency; the frequency and a reference frequency generated by a reference frequency synthesizer are fed into said display means which generates a visual display of the frequency difference between said fundamental frequency and said reference frequency.

Abstract: A system for subscription TV security which is comprised of a scramble signal generator which adds a modulated RF carrier signal to the TV channel transmission. Preferably the frequency of the scramble signal generator is selected to fall within the band of frequencies of the TV channel between the video carrier and the audio carrier. The TV channel is transmitted to receivers encoded with the scramble signal carrier providing false and misleading information, preventing the receiver from reconstituting a coherent picture or sound while this scramble signal is present. The transmitted signal is decoded, (i.e. scramble signal removed), restoring regular reception by filtering with a sharply tuned high-Q notch filter attached to the drop line going to a TV receiver. By careful selection of the band width and attenuation of the filter and pre-emphasis of the channel band, degradation of the video information is prevented.
