Abstract: 1,225,292. Colour television; amplitude modulators; transistor frequency changers. ZENITH RADIO CORP. 4 April, 1968 [21 July, 1967], No. 16358/68. Headings H3R, H3T and H4F. P.A.L. signals are converted into N.T.S.C. signals in a circuit wherein the P.A.L. chrominance signals separated out by amplifier 14 from the output of receiver 11, are applied in anti-phase, by means of transformer 22, to two inputs of a balanced modulator comprising transistors 20, 20<SP>1</SP>, 20<SP>11</SP>, 25, 25<SP>1</SP>, and 25<SP>11</SP> and the synchronous output of a frequency doubler 17<SP>1</SP> at twice the chrominance sub-carrier frequency is applied in phase to a second pair of inputs of said balanced modulator during odd time intervals. Thus during said odd line intervals the balanced modulator produces a difference frequency side band output having the same sub-carrier frequency as the initial P.A.L. signal but with the phase and modulation sequence reversed. During even line intervals a bi-stable circuit 17<SP>11</SP>, controlled by the horizontal sync. pulses and controlling the frequency doubler output, produces a signal which, via transistor 50, unbalances the modulator, whereby the chrominance signal passes unaltered therethrough. The output of the modulator is connected to a colour demodulator 16 and comprises consecutive line chrominance signals all having the same phase sequence, i.e. an N.T.S.C. signal. The balanced modulator comprises two difference amplifiers or long-tailed pairs, a first pair comprising transistors 20 and 20<SP>1</SP> with a transistor 20<SP>11</SP> forming a high impedance emitter input and the second pair comprising transistors 25 and 25<SP>1</SP> with high impedance emitter input transistor 25<SP>11</SP>. The collectors of the pair transistors are cross-coupled to load resistors 21 and 26. The bases of transistors 20<SP>1</SP> and 25<SP>1</SP> are coupled to ground by capacitor 23 and the frequency doubler output is connected in phase to the bases of transistors 20 and 25. The bases of transistors 20<SP>11</SP> and 25<SP>11</SP> receive the chrominance signals in antiphase. A difference frequency signal will thus appear across load 21. During the even lines transistor 50 is rendered conductive and unbalances the modulator. A potentiometer 53 is adjusted so that the amplitudes of the output signals for the balanced and unbalanced conditions of the modulator are equal. A circuit, substantially corresponding to Fig. 1, but comprising integrated circuits is described (Fig. 2, not shown).

Abstract: 1290188 Riveting AERPAT AG 3 Oct 1969 [7 Oct 1968] 48713/69 Heading B3U An adapter, Fig. 2, for a pneumatically operated pulling tool comprises a threaded mandrel 43 adapted to be secured to a pulling member 15, Fig. 1, of the tool so as to be longitudinally movable therewith and rotatable with respect thereto, and a trigger 49, the actuation of which sequentially causes the mandrel to rotate in one direction, the operation of an actuating member 34 of the tool to retract the pulling member 15 and the mandrel to rotate in the opposite direction. The apparatus is used to place a threaded fastener in an aperture in a workpiece wherein an internally threaded nut portion is pulled into a tubular body portion (Fig. 9, not shown). In operation, a trigger block 109 is pulled to the right to cause a tab member 134 to contact an oblique guiding face (145), (Fig. 5b, not shown) of a lever 103. As the tab member 134 is guided along the face (145), it pivots about a pivot rod 133 so as to be positioned beneath a cam face 142 of an adjacent lever 102. As the block 109 is moved further rearwards, the lever 102 is raised about a pivot 104 by the member 134 to open a valve 47. Compressed air is thereby allowed to pass through the valve 47, via a line 31, pipe 87 and bore 89, and through conduits into a turbine chamber 74. A rotor 73 secured to the mandrel 43 is rotated by the compressed air so that the mandrel may be screwed into the threaded nut portion of the fastener. When the tab member 134 moves beyond the lever 102, the latter is lowered and the valve 47 closed, after which a rear face 129 of the block 109 moves the trigger 34 of the tool a sufficient distance to actuate linkage 36-38 to open a valve 18. Compressed air can then flow from the line 31 into a cylinder 27 via a bore 25 to raise a piston 21 and rod 22 which forces hydraulic fluid from a cylinder 24 into a cylinder 13 via a bore 28 so that a piston 14 and attached pulling member 15 are moved rearwardly. The mandrel 43 is thus retracted to cause the fastener to shear at the junction between the nut portion and the body portion and the former to be pulled into the latter. When the trigger block 109 is released, it returns to its initial position by a spring 126. During this movement, the valve 18 is closed to return the mandrel to its initial position and the tab member 134 is pivoted about its pin 133 by a guiding oblique face 144 of the lever 102 so that it is positioned beneath a cam face 143 of the lever 103. The lever 103 is thereby raised about a pivot 106 to open a valve 46 which rotates the mandrel 43 in the opposite direction to unscrew it from the fastener. When the tab member 134 has moved past the cam face 143, the lever 103 returns to its initial position and the valve 46 is closed. In a modification (Figs. 10-12, not shown), the mandrel is rotated by a pin (156), projecting from an arcuate pawl (154) attached to the rotor, engaging a pin (153) secured to the mandrel.
