[Also in Group XXXI] An auxiliary hydraulic control system for the operation of an auxiliary hydraulic implement actuator from the main hydraulic control system of a tractor includes a conduit through which the pump of the main system discharges when the actuators are stationary, the conduit being formed with a constriction to maintain a back pressure and thus ensure a rapid response of the auxiliary actuator on operating the controls. In the embodiment of Fig. 1 the main control system comprises a ram 5 supplied from a pump 1 through a conduit 6. The auxiliary system comprises a supply conduit 9 leading through a branch 9a to an auxiliary actuator and through a conduit 11 having a constriction 12 to a sump. When a selector valve 13 is positioned as shown, oil discharged from the pump returns via conduit 11 and the constriction to the sump, and a back pressure is maintained on the discharge side of the pump. In a modification the selector valve controls two auxiliary control systems, and may also control the main actuator. In the embodiment of Fig. 13 a selector valve 24 is movable into three positions. In a midposition the supply conduit 9 communicates with a constricted discharge conduit 25, and the oil in an auxiliary actuator 35 and conduit 27 is trapped. In a lower position the valve closes conduits 9, 25, 27 and oil from the pump opens a non-return valve 29 and passes to the actuator. In an upper position the conduits 9, 25, 27 are in communication and the oil from the actuator is released. Specifications 470,069 and 470,087, [both in Group XXXI], are referred to.

Abstract: 1,101,161. Transistor logic circuits. MOTOROLA Inc. 3 Feb., 1965, [13 Feb., 1964], No. 4715/65. Heading H3T. In an integrated logic circuit, input signals are fed to the base of one (58) of a pair of differentially connected NPN transistors, whilst temperature compensating bias (Fig. 1, not shown) is fed to the base of the other transistor (64), the output being directly coupled to a further transistor (72 or 74) so as to be compatible with the input of a similar logic circuit. Fig. 3, shows a logic circuit in which the common current of a long-tailed pair of transistors 58, 64 is stabilized by transistor 63 having degenerative feedback via resistor 66. Temperature stabilizing diodes 67, 67<SP>1</SP> are provided. Alternatively, if transistor 63 is of germanium, a single silicon or gallium arsenide diode 67 may be employed. A single gallium arsenide diode 67 may be used with a silicon transistor 63. OR logic is provided at the output of emitter follower 74 whilst NOR logic is available at the output of 72. In Fig. 1 (not shown), the temperature stabilizing bias is supplied via an emitter follower to the base of transistor 64. In Fig. 2 (not shown), the base bias for transistor 63 is derived from a resistor connected to the supply 32. The circuits described are suitable for integrated construction on single substrates of semiconductor material. The transistors are arranged to be operated out of saturation so as to minimize charge storage effects.

Abstract: 941,223. Selective punching machines. CREED & CO. Ltd. Nov. 3, 1961, No. 5236/63. Divided out of 941,222. Heading B4B. Perforating apparatus comprises a die-plate, a plurality of punches arranged in rows and columns, means for supporting all the punches for movement towards the die-plate and thereafter to cause all the punches to perforate a recording medium by rows, or columns, in a selected order. The apparatus is adaptable for use in the data processing equipment described in Specification 941,222. The apparatus, Fig. 2, comprises a die-plate 1 and a stripper plate 2 between which a tape T is fed, the plates incorporating holes H and FH arranged in four rows and nine columns. Corresponding to the holes are punches 5 and guide pins 17, Fig. 3, which are reciprocable vertically relative to the die-plate by means of operating bars 8 secured to carriers 9 coupled to a rod 10 which engages in a cam track 11 of a cam plate 12 secured to a rod 13 which is coupled to an operating lever 14 in turn coupled to a solenoid armature SA. The punches have slots S, Figs. 3 and 4, the upper ends of which are engageable by the upper sides of tapered operating bars 8, the arrangement being such that when the bars are moved downwardly, the pins 17 of the rows first engage in the feed holes FH in the tape after which the punches in columns C1 to C8 are engaged successively to effect columnwise perforation of the tape. In a modification, Figs. 5 and 6 (not shown), the operating bars are of uniform width throughout their lengths and the slots in the punches of one column, or row, are wider than those of punches in the next adjacent column, or row. In another modification, Figs. 7 and 8 (not shown), the punches in one column are shorter than those in the next adjacent column and so on. In a further modification, Figs. 9 and 10 (not shown), for effecting row-wise perforation of the tape, the punchoperating bars are stepped on their lower sides and are of different depths. In operation, when a signal is applied to a solenoid associated with the armature SA a lever 14 is pivoted in directions B and C, Fig. 2. In its pivoting movement in direction B, it causes the guide pins 17 to engage feed holes FH in the tape and the punches 5 of rows R1 to R4 to punch the tape.
