IPC: H04N9/66
Filed: 1970-01-28
Abstract: 1297675 Colour television receiver MOTOROLA Inc 28 Jan 1970. [10 Feb 1969] 4142/70 Heading H4F In a colour television receiver an integrated circuit colour demodulator system 50 comprises three gated synchronous full-wave demodulators 60, 70 and 80 each including two pairs of switching transistors 61, 62 and 63, 64 and input transistors 65 and 66. The transistors in each pair are rendered alternately conductive by means of a reference signal at the colour subcarrier frequency which is derived from the colour bursts. This reference signal has the correct phase for demodulating the red chrominance information on line 56 (demodulator 60), the blue on line 57 (demodulator 80), and by mixing the two, resistors 58 and 59, the correct phase for the green information (demodulator . The chrominance modulated subcarrier (NTSC-type) is fed with opposite phase (transformer 32) to each input transistor of each demodulator together with the luminance signal 37, the contrast of which may be adjusted, 36, before it is fed to the centre tap of transformer 32. With this arrangement, red, green and blue signals are formed at the outputs and are filtered before being displayed. To provide the proper relative amounts of gain for the demodulators, the red and blue demodulators 60 and 80 have shunting resistance circuits 67 and 87 connected across the input transistor circuits, and the green demodulator has a shunt 78<SP>1</SP> connected across equal taps on voltage dividers connected to the outputs thereof. Since the luminance singla is balanced with respect to the shunt devices it is unaffected thereby. Blanking functions may be incorporated into the design of integrated circuit 50 by applying the blanking signals to transistor 96 and via a Darlington loop amplifier 90 to the collectors of all the switching transistors in demodulators 60, 70 and 80, so that blanking signals are derived at the outputs of emitter followers 91, 92, and 93. Background brightness control of the output of the emitter followers 91, 92 and 93 may be affected through brightness control circuit 97.

Abstract: 1302869 Drilling machines; milling machines; lathes CARDING SPECIALISTS (CANADA) Ltd. 18 Nov 1970 [25 Nov 1969] 57537/69 Headings B3C B3K and B3T A machine tool has a work-table 1 (Fig. 1) pivoted about an axis A, a tool-holder 3 pivoted about a parallel axis B and means for causing relative movement of the work-table and toolholder towards and away from each other, pivoting of the work-table and tool-holder being through equal angles in the same sense of rotation. The work-table and tool-holder are interconnected by a parallelogram linkage 11, 12, 13, whereby longitudinal movement of rod 13 causes equiangular displacement of the worktable and tool-holder in the same sense. Thus, the usual sliding movements of the work-table and tool-holder are replaced, at least in part, by pivoting movements.  The axes A, B may be vertical, in which case relative vertical movement of the work-table and tool-holder may be achieved by sliding. Alternatively, the axes A, B may be horizontal, in which case relative horizontal movement of the work-table and tool-holder may be achieved by sliding.  Separate drives to the work-table and toolholder may be provided to turn them through equal or different angles. A tool-carrying part of the tool-holder is adjusted longitudinally upon pivotal movement of the tool-holder, to ensure that the distance between the tip of the tool and a work-piece on the work-table is constant irrespective of the relative angular positions of the work-table and tool-holder. This adjustment is effected automatically through a suitable template 8 which acts on a movable part of the tool-holder. Preferably, relative movement of the worktable and tool-holder in both horizontal and vertical planes is achieved by their pivoting. In this case the work-table 20 (Fig. 2) is mounted in a mount 22 for pivoting about horizontal axis E-F while the mount is pivotable about vertical axis G-H. A similar arrangement applies to tool-holder 21. For effecting linked movements about the respective axes, connecting rods 26, 31 are provided. Joints 32, 33 are ball joints. A practical embodiment of this form of construction is described with reference to Fig. 3. In this, the spindle is rotatable by electric motor 84 and can be fed by a rack-andpinion mechanism 75, 76. In another form (Figs. 7 and 8, not shown), a plurality of tool-holders (123-125) are spaced about a common work-table (120) or vice versa. The work-table(s) may have a turntable top which can be indexed. In another form the work-table may carry a head-stock rotatably mounted thereon about an axis normal to the tool which will be stationary. This arrangement functions in the manner equivalent to a lathe. Milling and drilling also are referred to.

An alternative embodiment utilizes cam-operated control valves 26, Figs. 6-9 (not shown), where the cams are mounted on a rotatable shaft, of which the drive mechanism must be switched on (as well as supplying compressed air) before the electrode can be moved.

Abstract: 1319897 Testing castings for-core removal TRW Inc 20 Aug 1971 39204/71 Heading G1S Parts such as a turbine blade 10 made by casting metals around cores of say siliceous material which is afterwards dissolved by acid and so on; are checked to see if any core material remains by first filling the core passages 13 with radiographically detectable powder 14 subjected to vibration compaction and then exposing the blade 10 to penetrating radiation 15 such as X or gamma rays. Behind the blade is a radiation sensitive film 16 which shows up residual core materials (17), Fig. 3 (not shown) as indications 18 on the film. Direct fluoroscopic examination or electronic image enhancement may also be employed if desired. When the powder attenuation co-efficient and the degree of packing of the powder in the passages provide radiation characteristics similar to that of the casting itself then the part appears to be solid except where residual core materials show up. Tables and formulae in the specification enable the mass attenuation co-efficients for various metals to be determined and the powder particle size and acceleration for compaction to be found.
