Title: Dropout detector circuit
IPC: G11B20/06
Filed: 1976-07-02
Abstract: The signal read from a recording carrier, particularly the video signal, is supplied to the input of an amplifier (19). The output of the amplifier is connected via a filter (20), a rectifier arrangement (21) and a low-pass filter (22) to a first input of a threshold device (23) constructed as Schmitt trigger. A second input of the threshold device is also supplied with the signal from the output of the amplifier via a rectifier arrangement (26) acting as amplitude detector and a further low-pass filter (27). When the ratio between the amplitude of the signal supplied to the first input of the threshold device and the amplitude of the signal supplied to the second input of the threshold device has dropped to a particular value, the threshold device generates a switching signal. This indicates that dropout interference is present.
Patent ES-451894-A1 (ES)
Title: Resistive fluid detecting means
IPC: F24H1/18
Filed: 1976-09-27
Abstract: A resistive fluid detecting means utilizes a probe means having three electrically conductive areas that are interconnected between a power source and an amplifier. The detecting means is particularly useful in detecting the presence or absence of water in a boiler used in a heating plant. The presence of water between two of the electrically conductive areas reduces the resistance of that path so that the amplifier responds and operates an output switch, which in turn can be used to energize a fuel burner for the boiler. If boiler scale builds up on the probe means or if the water or fluid rises too high, the electrically conductive areas shunt current away from the amplifier and allow the output switch to open.
