Patent ES-438291-A1 (ES)
Title: Defect compensation systems
IPC: G11B20/06
Filed: 1975-06-06
Abstract: In a video disc player, an FM signal recovered from the disc is subject to frequency demodulation to obtain a composite color video signal. In the composite signal, chrominance information appears in the form of a modulated subcarrier buried in spectrum troughs in the midband of a wider band luminance signal. The composite signal is applied to a modulator to develop amplitude modulated carrier waves, which serve as the "normal" signal input to a 1H delay line. Comb filter circuits respond to the delay line input and output to obtain separated chrominance and luminance signal components, which are suitably processed for delivery to color image display apparatus (e.g., color television receiver). The amplitude modulated carrier wave output of the delay line is also utilized as a "substitution" signal input to the delay line, replacing the normal signal input when a defect detector, monitoring the output of the FM demodulator, indicates the onset of a picture defect. The substitution signal path includes a network providing respectively different amounts of phase shift at the carrier frequency, and at the sideband frequency associated with the color subcarrier. In a variant of the aforesaid arrangement, switching between normal and substitution signals is effected in the video domain. A composite signal from the output of the FM demodulator is normally supplied to the amplitude modulator input, but, upon defect detection, a detected version of the amplitude modulated carrier wave output of the delay line is substituted.

Title: Driving circuit for the supply of a current to a coil and its use in a printing device.
IPC: H01H47/32
Filed: 1980-06-23
Abstract: A print hammer drive circuit is driven by a voltage supply having inherent voltage variations. The driving current is applied to the print hammer coil and the level of the current in the coil detected. After the level of the current in the coil reaches a predetermined maximum level a timing circuit is initiated to control the duration of application of maximum current. Variations in supply voltage on the duration and force of strike of the print hammer have greatly reduced since all timing is based relative to the time that the predetermined drive current level is achieved as distinguished from timing which includes the rise time of the driving current wave form. Also the effects of variations in inductance from coil to coil can be compensated for by adjustment of the timing circuit.

Title: Apparatus for obtaining a sample of liquid from near the bottom of a liquid-filled container.
IPC: G01N1/10
Filed: 1980-09-01
Abstract: A liquid-sampling gauge for obtaining a sampling of liquid (e.g. water) from near the bottom of a liquid-filled container (e.g. a crude oil cargo tank) and for determining the depth of the water layer in the container. The gauge comprises a cylinder which is open at its upper end and closed at its lower end. A spring-biased valve normally closes an inlet opening through the lower end of the cylinder. The cylinder fills with oil through its open upper end as it is lowered into the liquid-filled container. As the cylinder reaches bottom, a valve actuator on the cylinder engages the bottom of the container and continued downward movement of the cylinder opens the valve which allows water on the bottom of the container to flow into the cylinder to displace oil from the cylinder. Flow will continue until the interface level inside the cylinder equals the level of the water layer in the container. Upon lifting of the cylinder, the spring-biased valve closes, trapping the water in the cylinder for retrieval, measurement and analysis.
