Abstract: 1373943 Colour television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 25 Nov 1971 [28 Nov 1970] 54806/71 Heading H4F  A colour television signal is formed with the luminance information in the scan part of each line period, and at least part of the chrominance information in a time-compressed form during the back porch of the line blanking period. The chrominance information may be R-Y and B-Y (or I and Q) signals occurring line sequentially, or the R-Y (or I) signal may occur during every back porch, the B-Y (or Q) signal being modulated on a sub-carrier during the scan part of the line period, or the single chrominance signal of a land system may occur during each back porch. The resulting signal may be recorded on magnetic tape or a video record or may be broadcast. In the transmitter shown in Fig. 2, for producing line sequential colour difference signals in the back porches an oscillator 7 and frequency dividers 8-12 produce the signals required to operate switch 16 and circuit 23, which operates switches 19, 22 in synchronism. A memory 18 is provided which receives write signals from frequency divider 8 during the line scan period to write in the R-Y or B-Y signal from switch 16, memory 18 receiving read signals from frequency divider 2 during the back porch, so as to read out the stored signals at eight times the speed with which they were written in, these signals then being passed via switch 19 to output 21. The luminance signals are passed to switch 19 via a one-line delay line 20. The phase of oscillator 7 is controlled by phase comparator 13 receiving line sync. signals 5 from 14 and a line frequency signal from frequency divider 11. Memory 18 may be magnetic, a cathode-ray tube or a "bucket-brigade delay line". The receiver (Fig. 3, not shown) uses two memories in series to produce simultaneous Y, R-Y, and B-Y signals for each line. Alternatively the receiver may use three memories in parallel.

Abstract: 1333717 Scanning monochromator PERKINELMER CORP 18 Nov 1970 [19 Nov 1969] 54893/70 Heading G2J [Also in Division G1] An automatic scanning monochromator has several gratings and associated filters to remove unwanted order refractions and the grating when moved into operative position signal a unique indication to the wavenumber computer. The spectrum is moved through by tilting the grating about an axis under control of one of two cam profiles (depending on the physical displacement necessary with the grating in use) and its position is signalled with reference to the cam angle ("coarse" encoder) and a higher speed driving shaft ("fine" encoder). This information is binary coded and used to indicate the wavenumber that is being used. The operator has a control for setting up scans of appropriate speed and wave length spread and the logic unit suitably positions the grating and filter (by stepping motors) and the cam (by drive motors) accordingly. For this purpose the actual position of the elements and the desired position are compared and the latter corrected.

Rolls 5 which shape and reduce the crosssection of a cast strand 4, e.g. of carbon or alloy steel, are disposed at a location where the molten core thickness would be 5-30 mm., without the rolls, to reduce the core length so that the core tip closely precedes the plane in which the strand assumes its rolled shape, the casting conditions being adjusted, according to the cross-sectional areas and velocities of the strand (determined by sensing units 1, 2) upstream and downstream of the rolls 5, to obtain at the location a desired theoretical proportion of core in the strand cross-section, which proportion would exist if the rolls were absent. The core size is adjusted by altering the strand withdrawal or cooling rate. There may be extra shaping rolls 6-8.

Title: Impedance comparing circuit

Filed: 1972-12-06
Abstract: 1395208 Measuring impedance changes ADE CORP 6 Dec 1972 [9 Dec 1971] 56332/72 A bridge for comparing a sensor impedance 30, Fig. 1, which although shown resistive may be capacitive, with a reference impedance 32 includes cross-coupled diodes 20 and D. C. blocking impedances 14, 16, and is energized by an A.C. source 12. The bridge operates as follows. Consider first node 24. When the uppermost point of the bridge is positive current will flow through impedances 16 and 30 to ground tending to create a potential at node 24 proportional to the sensor impedance 30. When the uppermost point of the bridge goes negative, current flows from ground via impedances 32 and 16 tending to create at node 24 a potential, of the opposite polarity, proportional to the reference impedance 32. Because of the smoothing action of impedance 16, and a path to earth via a low pass filter 36 and a meter 40, the resulting potential at node 24 is proportional to the difference in impedance between the sensor impedance 30 and the reference impedance 32. In a similar manner the same potential, but opposite in polarity appears at node 22. These potentials are both indicated on meters and their difference is available from a differential amplifier 42. In a modification Fig. 2 (not shown) the impedances 14 and 16 are replaced by two inductances (46, 48) mutually coupled. The arrangements described have the advantages that the diodes, when conducting are fully conducting- thereby avoiding non-linearities, and that the output signal is significant relative to ground.
