Abstract: 1,184,568. JK flip-flops. MULLARD Ltd. 2 May, 1967, No. 20191/67. Heading H3T. A clocked JK flip-flop of the master-slave type includes master and slave flip-flops E, H, input gates A, D, intermediate gates F, G, and an output buffer I, all arranged substantially as shown in Fig. 1. Assuming that Fig. 1 is in the K state, the q output blocks gate A but the #q output will combine with a " 1 " from clock input C and a " 1 " at J to changeover a " master " bi-stable circuit E. At the end of the clock pulse the inverted clock pulse from C and the output from bi-stable E enable a gate G which produces a J output from buffer I. It also changes a slave bi-stable circuit H to the J state to hold the state and to prepare gate A for a K pulse and to block gate D. In Fig. 2 additional gates are provided to prevent a change from " 0 " to " 1 " during the clock pulse due to a delay in the clock relative to a previous stage. Thus with the circuit in the J state and K equal to 0, the output of " a " is 0 and the input to B via D 1  is 0. Line Y is " 1 " due to the inverted output from C. When the clock pulse occurs the inverted output from C disables gate " a " so that K is isolated from A. Fig. 3 (not shown) illustrates a current switching logic circuit suitable for use in Fig. 2. It comprises " a " and " b " gates (T 1 -T 3 ) and (T 4 -T 6 ), A and D gates (T 7 -T 9 ) and (T 10 - T 12 ), a B gate (T 13 -T 15 ) and an input buffer C (T 16 , T 17 ).

A mobile jib-crane which luffs but does not slew is mounted on a semi-trailer 1, Fig. 1, and is counterbalanced for normal loads by the winding gear and for heavier loads by a towing vehicle 31. The front of the semi-trailer has a plate 32 which abuts a block 33 on the tractor if the crane starts to tip over. Four pairs of steerable wheels 3 are mounted on beams 4 pivoted to the chassis at 6. A winch 29 luffs the jib by a rope 25, which passes round sheaves 23 on telescopic struts 22, and a rope 20. To prevent self-luffing when the jib approaches a vertical position a weight 40, which is moved along guides 41 by a cable 42, is provided to counterbalance the weight of the sheaves 23. For handling heavy loads the track of wheels 3 can be widened. To lower the jib for transport a jack 39, Fig. 2, is operated to raise a track 38A which bears against wheels 37 on the jib foot thus enabling the pivot pins to be withdrawn. The foot of the jib is drawn to the rear of the trailer by a cable and sheave, not shown, and a locking pin 12 is removed to permit jib foot brackets 10 to be swung down into the position shown in chain dotted lines. The jib foot can now run back with the wheels 37 in tracks 38 until the jib is flat on the trailer.

In a position or speed measuring apparatus of the type using co-operating gratings, light from some point on a measuring grating falls on two index gratings so positioned that photo-cells cooperating therewith produce signals having a predetermined phase difference. The light may be switched to fall alternately on the index gratings, but preferably is made to fall on both continuously by using a beam splitter. The phase difference may be 90 when it is desired to produce sine and cosine signals, or 180 when it is desired to connect the outputs in opposition and so remove noise and the static D. C. level by "Common-mode rejection". Both these uses may be combined in one apparatus, Fig. 6. A measuring grating 70 is fixed to a shaft 71, the angular position or speed of which is to be measured, and illuminated by a lamp 73. By means of beam splitters 77A; 77B; 77C, the lens 76 forms images the grating 70 on to index gratings 78, 78A; 74, 74A. The first splitting, by 77A, is to produce sine and cosine signals and to this end the gratings 78 and 78A are adjusted so that their position relative to the image are in quadrature relative to 74 and 74A respectively. The second splitting, by 77B and 77C is to produce signals from photo-cells 79 and 79A and from 74 and 74A that are in antiphase and may be connected to the inputs of differential amplifiers 83, 88 for common mode rejection. The beam splitters 77A, 77B, 77C, may be combined to form a single block, Fig. 7 (not shown). If the gratings are very coarse, the lens 76 may be omitted. The index gratings may be single slits.
