Title: Three pump hydraulic system for a vehicle
IPC: E02F9/22
Filed: 1970-02-24
Abstract: 1,243,761. Hydraulic systems for vehicles. GENERAL SIGNAL CORP. 24 Feb., 1970 [9 May, 1969], No. 8870/70. Heading B7H. In an hydraulic system for a construction vehicle having a steering circuit 13 and an implement circuit 14 supplied by respective engine-driven gear pumps 15, 17, and a demand valve 23 arranged as described in Specification 1,091,836 to split the output of a third pump 16 between the circuits 13, 14 in such a way as to maintain a constant total flow to the steering circuit 13 over a major part of the speed range of the engine 18, overheating due to excessive oil discharge through an implement circuit relief valve 45 is avoided by providing between the demand valve 23 and the implement circuit 14 an unloader device 27 which diverts oil from the demand valve 23 to a reservoir 19 when pressure in the implement circuit exceeds a predetermined value. The unloader device 27 comprises an unloading valve 31 for opening and closing an exhaust passage 32 to the reservoir 19, a first pressure cylinder 35 urging the valve 31 towards the open position, and a second pressure cylinder 36 urging the valve 31 towards the closed position and subjected to the pressure in a passage 37 which is supplied through a restrictor 38 from a conduit 26 between the demand valve 23 and the implement circuit 14 and leads through a pilot valve 41 to the reservoir 19. When the pressure in the implement circuit 14 exceeds the predetermined value, the pilot valve 41 opens against spring- loading 42 to create a pressure drop across the restrictor 38 so that the cylinder 35 opens the unloading valve 31. A piston 43 subject to implement circuit pressure in the conduit 26 beyond a check valve 33 holds the pilot valve 41 open until the implement circuit pressure decreases. In an alternative arrangement, Fig. 2 (not shown), the unloader device is connected between the pump 17 and the implement circuit.

Abstract: 239,797. Morris, A. W. April 7, 1925. Latches, preventing operation of; lock mechanism, slider - type; locks, attaching; keyholes; reversible locks.- A latch mounted in a hole in the door at rightangles to a hole containing the handle spindle and lock mechanism is shot by a spring and retracted by the spindle, which is formed with a constricted part adapted to be engaged by notches in sliding plates unless these places are set. The mechanism is reversible for right or left hand doors. The latch 43 slides in a hole 44 in the door 14 and is pressed outwards by a spring 48. It has a flat part 49 engaging the straight part of a D- shaped opening in the front plate 50 to prevent rotation. The tail of the latch has a T-shaped head 45 which is passed through one of the holes 46 in side-plates 17, according to whether the latch is to be used as a left or right hand latch, and turned to engage in the hole 47 in the yoke 41 which surrounds the spindle 26 and is acted upon by the follower 40. The handle spindle 26 has a knob 27 at each end and has a waist or constricted part 29. It turns freely in an inner plate 12, an outer laminated plate 19 and an intermediate plate 18. The plates are spaced apart by distance-pieces 16, 17, the pieces 17 being curved round bolts 20 which connect the inner and outer plates and hold the whole together. Between the plates 12 and 18 are a number of sliders 30 each having a central circular hole 31 with upper and lower extensions 32, a lower notch 33 and an upper hole 34. Normally, these sliders rest in their lowermost position so that the waist 29 of the spindle is engaged in the upper recess 32 and the spindle cannot be turned to operate the latch. The spindle is released from outside by the key 24 which is inserted with its bit 53 facing downwards so that the bevel 54 raises all the sliders, and turned so tlat the sliders drop on the appropriate steps of the bit and register the circular holes 31 with the spindle which can then be turned. From inside, the spindle is released by turning the finger-piece 38 of the disc 36 from one end of the bracket 37 to the other, thereby causing a pin 35 situated in the hole 34 of the sliders to lift them so as to register the circular slots 31 with the spindle as before. The sliders are guided by the bolts 20. The key has wings 56 to limit its degree of insertion. The keyhole is stepped in the laminae 19 so that the wings can penetrate the outermost plate only, the slot therein forming a stop to limit the degree of rotation of the key. A face-plate 52 with an appropriate keyhole may be added after the lock has been fixed. The lock can be used on doors opening to either left or right hand by drilling the hole 44 on the appropriate side of the hole 13, putting the latch-tail 45 through the appropriate hole 46 and turning the spindle so that the follower 40 is in the correct side. To facilitate the attachment of the latch-bolt to the yoke, a temporary screw 55 is inserted to hold the yoke while the latch-tail is engaged, after which it is removed.

Abstract: 1369715 Timing circuits FERRANTI Ltd 19 Feb 1973 [29 Feb 1972] 9325/72 Heading H3T A timing circuit includes a resistor R 1  and a capacitor C 1  having their junction point connected to the input of an amplifier A 1  having substantially unit gain and a potential divider R 2 , R 3  connected between the amplifier output and a voltage source E, an intermediate point X on the divider providing the charging voltage for the elements R 1 , C 1 . The amplifier A 1  may be a differential amplifier or a single input amplifier. In operation, as the capacitor C 1  charges, the input and the output of amplifier A 1  are maintained at the same voltage level. A larger time constant is obtained as a result of bypassing part of the charging current for C 1  via R 2 . The timing circuit may be followed by a threshold detector A 2  having a threshold bias derived from the same voltage source E. The timing circuit may be used in servo or stepping motor applications (Figs. 3, 4, not shown) by connecting a pair of parallel connected diodes across either R 1  or R 2  so that the output of amplifier A 1  follows rapid changes in the input E either instantaneously or very slowly, respectively.
