Abstract: 1,227,778. Digital/analogue converters. GENERAL DYNAMICS CORP. 30 May, 1968 [3 July, 1967], No. 26067/68. Heading G4H. Binary coded signals in register 16 (Fig. 1) representing an angle # are converted into signals representing sin # and cos # by using the higher order bits which represent the quadrant in which the angle lies to modify a reference voltage and the lower order bits to generate two digital words L 1 ... . L n , L<SP>1</SP> 1  ... L<SP>1</SP> n  approximating to the absolute value of sin # and cos #, the modified reference signals VR1, VR2 and the two words being fed to digital to analogue converters 22, 24 the outputs of which are connected to an analogue indicator 30 responsive to the ratio of the outputs of the converters. In the embodiment described logic circuitry (52, Fig. 2, not shown) receiving the two highest bits # 11 , # 12  of the bits in register 16 control phase inverters (48, 50) so that the modified signals (VR1, VR2) are obtained, the phase of which relative to the reference signal represents the quadrant. From the lowest eleven bits, signals S1 . . . S 10 , C 1  . . . C 10  (Fig. 3) are derived in exclusive OR circuits so that, for example Sj = #j.# 11  + ## j .## 11 , the lowest bits of these signals shifted in sine and cosine code generators 102, 104 in accordance with the values of the higher bits to generate the digital signals L 1  . . . L 10 , L<SP>1</SP> 1  ... L<SP>1</SP> 10 . The digital signals are fed to transistor switches in the converters 22, 24 to selectively switch in resistors in a ladder network so that output signals KVR1 sin # and KVR2 cos # are fed via amplifiers and transformers 110, 112 (Fig. 3) to a servo mechanism 114 including a resolver 116.

Abstract: 1,228,936. Pulse generators. BURROUGHS CORP. 12 July, 1968 [11 Aug., 1967], No. 33382/68. Headings H3A and H3T. In a pulse generator having the time (26, Fig. 2, not shown) between like points on adjacent input pulses (27) variable, a pulse timer 39, 61 is responsive to the time (26) between like points on adjacent input pulses (27) to discharge an RC timing circuit 69, 71, which has a time constant longer than the pulse time (31) generated by a pulse generator 37, 53, to vary the pulse time (31) of the output from the generator 37, 53 so as to maintain a predetermined constant ratio between the time between adjacent input pulses (26) and the pulse time (31) As shown signals of varying frequency are obtained from a magnetic tape or disc via a transducer 11. The output is rectified via diodes 13, 15 and fed by a pulse amplifier 21 to trigger a Schmitt trigger circuit 23. The output (27, 27a) from this circuit 23 forms the input pulses to a monostable pulse generator 37, 53 and a pulse timer 39, 61. Assuming transistors 37 and 39 are OFF and 53 and 61 are ON. A pulse (27) from Schmitt trigger 23 turns transistor 37 ON and transistor 53 OFF. Feedback via diode 77 then maintains this state. Transistor 39 also switches on after 37 due to a delay introduced by capacitor 68. Capacitor 71 is then discharged by the conduction of 39. Transistor 39 then turns OFF at the end of the input pulse 27 and capacitor 71 starts charging. Also capacitor 55 of the pulse generator 37, 53 is charging (73) until the .voltago across it is sufficient to turn ON transistor 53 to end the output pulse 31 from D and turn OFF transistor 37. Capacitor 71 continues to charge and the voltage across it is coupled via transistor 61 to point C so as to modify the charge on capacitor 55. The pulse time (31) is then maintained at a predetermined constant ratio to the input pulse repetition rate (26). Clamping diode 63 limits the maximum voltage across 55 and diodes 33 and 35 isolate the inputs of the pulse generator 37, 53 and pulse timer 39, 61.

Abstract: 1,250,092. Foldable earthworking implement. MASSEY-FERGUSON Inc. 31 March, 1969 [1 April, 1968], No. 16702/69. Heading A1B. [Also in Division E2] An earthworking implement 10, comprises a centre section 12 and at least one side section 14 interconnected at their adjacent ends by a first hinge means 36 having a hinge axis XX which, in the working position of the implement, allows relative vertical pivoting between the sections to accommodate unevenness in the ground, and by a second hinge means 38 having a hinge axis YY which diverges from said first axis so that when the sections are tilted forwardly from their horizontal working plane, the side section can be pivoted about axes XX and YY into a transport position. The folding axis YY may be inclined to the axis XX so as to extend rearwardly, inwardly and upwardly from the foremost point of the axis XX such that when the centre section is tilted forwardly to an angle with the horizontal that is complementary to the run of the horizontal and vertical angles of inclination of axis YY from axis XX, the side section can be folded forwardly about the folding axis YY to lie in a vertical plane. The forward transverse frame member 22 of the centre section 12 may be hinged to a pair of side sections 14, 16 by a universal hinge 34 including a clevis member 40, a hinge pin 42, a ball (44) Fig. 3 (not shown) and a rocket member 46 inclined to frame member 28 so as to lie in a plane perpendicular to the folding axis YY. The hinge 36 between rear frame members 24 and 30 can be locked, when the sections have been folded, by inserting a locking pin 56 into the aperture 54. Alternatively, the pin may be inserted into the apertured ears 58 to deactivate the folding hinge 38, which is positioned above the plane of the centre section 12, when the implement is operating. A hydraulic ram 88 acts via lever 82 and rods 84 to cause the centre section 12 to pivot about a hitch member 70, thereby tilting the section to allow the side sections to be folded forwardly and secured by brackets 102. The centre section 12 may be supported on ground wheels 90 and the side sections may have ground wheels 94 and tension rods 98 to relieve the strain on the hinges during earth working.
