Title: Quick-coupling device for the linking of agricultural implements to a tractor
IPC: A01B59/00
Filed: 1971-10-12
Abstract: 1349767 Tractor hitches J GAIL 12 Oct 1971 [26 Oct 1970 6 July 1971] 47516/71 Heading A1P A quick-coupling device for the linking of an agricultural implement to a tractor comprises coupling horns mounted by ball joints on the lower links of the tractor three-point linkage and provided with directing faces, and coupling eyes adapted to be disposed on the implement, the coupling of horns and eyes being rigid and being secured by retainers. In one embodiment a horn 15 (Fig. 5) held in an upward inclination by a weight 33, carries a lever 17 mounted on a pivot 31. The eye 21 (Fig. 10) mounted on the implement 19 has inner faces 22 which match the outer faces of the horn 15 when in the coupling position. In the coupling operation the horn 15 is placed under the eye 21 and lifted up; the long arm 29 of the lever 17 passes through a vertical slot 32, followed by the draft link 13; on full engagement of the coupling parts the shorter arm 30 of the lever 17 is swung by the weight of the longer arm 29 over a locking surface 24 at the top of the eye 21. To uncouple the implement the longer arm 29 may be swung upwards by means of a cable line within reach of the driver. In a second embodiment, shown in Fig. 13, the locking lever 114 has a pivot 115 and is held in the locking position by a spring 116, withdrawal from that position being effected by a ducted cable line 117. The rectangular coupling eye 118 carries a bush 120 with a locking surface 122 on the outside. The bush 120 is slipped over the usual coupling spigot present on the implement and secured there by a pin 124a which passes through a hole in the spigot and through two slots 121 in the bush. This arrangement allows the eye 118 to swing on the spigot, so as to be downwardly inclined prior to coupling, to facilitate the coupling. This may instead be achieved by the provision of eccentric drillings in the wall of the bush 120 and a sickle-shaped recess in the spigot which allows play of the pin. The spigot may be drilled together with the bush 120.

Title: Multistage hydraulic telescopic lifting jack
IPC: B66F3/28
Filed: 1973-10-12
Abstract: 1449020 Telescopic jacks MONTANHYDRAULIK GmbH & Co KG 12 Oct 1973 [2 Nov 1972] 47824/73 Heading F1D A telescopic jack comprises a cylinder 11, a piston 121 slidable in the cylinder 11 and carrying a cylinder 12, a piston 131 slidable in the cylinder 12 and carrying a cylinder 13, and ports 116', 118' in the wall of the cylinder 11 for co-operation with passages 123, 124 in the piston 121 in a manner which causes extension of the cylinder 12 followed by extension of the cylinder 13. To extend the jack, the cylinder 11 is pressurized through an inlet 113' and a non-return valve 114. Pressurization of the cylinder 11 extends the cylinder 12, fluid in the annular chamber 112 behind the piston 121 flowing to exhaust through the port 116' and a line 116. At the end of the stroke of the cylinder 12, fluid in the cylinder 11 flows into the cylinder 12 via the port 118' and the passage 123 now aligned therewith. This causes the cylinder 13 to extend, fluid in the annular chamber 122' behind the piston 131 flowing to the exhaust line 116 via a port 133 in the cylinder 13, a tube 124' fixed to the piston 121, the passage 124, and the port 116'. Retraction is effected by reversing the lines 113, 116 whereby pressure in a control line 117 opens the valve 114. Initially pressure in passages 124, 124' retracts the cylinder 13 until the piston 131 uncovers a port 126, thereafter the annular chamber 112' is pressurized first via the port 126 and subsequently directly from the port 116', whereby the cylinder 12 retracts.

The duct 6 is supplied with fuel through a meter 13 or solenoidoperated valves (not shown) from a crank-driven pump 19, and the fuel may be preheated by exhaust gases in a pipe 23. The second ducting type involves a three-cylinder engine (Fig. 2) in which the fuel is supplied to ducts 4, 5, 6 arranged with inlet ports 7, 8, 9 above the midstroke level of each piston and injection ports 10, 11, 12 arranged beneath the midstroke level of each piston. As shown in Fig. 2, as cylinder 3 fires, cylinder 1 is being charged with fuel, and cylinder 2 is effecting compression towards the end of its upward stroke.

[Also in Division D1] In apparatus for drying and shrinking textile webs, the web passes about sieve drum driers in a substantially tensionless manner during drying and the air flow is produced in a pulsating manner to pass therethrough. The web 16 is fed by a conveyer 17 to sieve drums 5 which rotate at a slower rate than the conveyer speed and the pulsating air flow circulated in the treatment chamber is produced by rotary discs 13 within the drums having apertures 15 co-operating with the perforated drum periphery. In a modification, fluttering of the web is achieved between the drums, by a perforated vibratory shoot which may have an additional, pulsating air flow, Fig. 4 (not shown); by utilizing the normal internal baffles within adjacent drums, Fig. 5 (not shown) to achieve an unstable air flow therebetween; or by utilizing longer internal baffles in adjacent drums to create unstable air flow into the wedge-shaped area formed between adjacent drums, Fig. 6 (not shown). Brushing rollers may be mounted adjacent the sieve drums which may rotate in various directions to enhance the shrinking effect.

Abstract: 1,019,620. Aircraft-arresting devices. P. B. FONDEN, and K. 0. T. WALANDER. Dec. 28, 1962 [Feb. 8, 1962], No. 48896/62. Heading F2F. In means for braking aeroplanes by arresting devices such as nets or wires 16, both ends of which are connected to fluid-pressure actuated brakes 12, the pressure of the fluid before its admission to the brakes is reduced from a higher to a lower value. This is effected by providing two or more pressure-reducing valves 3, 4 connected in series or parallel and a cut-off valve 8 or valves which can be controlled to vary the fluid pressure admitted to the brakes. As shown pressure fluid from a compressed-air container or the pressure side of a pump passes to the brakes 12 through a circuit comprising a lowoperating pressure reducing valve 3. A highoperating pressure reducing valve 4, and an electrically operated cut-off valve 8 on actuation of the braking cock 11 by means of arms 14 projecting from the brake drum 13 which is set into rotation by the wire 16. The cut-off valve is set either to a closed or open position in which respectively only the lower or higher operating pressure is admitted to the brakes. The cut-off valve may be controlled by a device adapted to measure the speed of the aeroplane at the beginning of the interception, or slightly before. This device comprises two brake drums which as the interception begins will rotate so that small permanent magnets 30 (Fig. 5, not shown) induce current impulses in transducers 31. These impulses are applied to a " clock " 33 which is started by the first impulse arriving and will then operate at a constant speed, the pulses passing through the clock up till a certain pre-set instant. Thus the pulses will freely pass through the " clock " as long as the pointer is in contact with the segment 35, but after that the circuit will be interrupted. From the " clock "  a certain number of pulses as determined by the speed of the aeroplane will proceed to a counter 36 which is arranged that after counting a certain fixed number of pulses it will apply one pulse to a relay 37 which will operate the cut-off valve so that the higher braking pressure will be applied to the brakes. For an aeroplane having a low speed the pulses will arrive spaced by relatively long intervals and therefore the clock will overrun the critical instant before the pulse which would pass through the counter to operate the relay has arrived. However, for a high-speed aeroplane the pulses will arrive at shorter intervals and the pulse which will operate the relay will arrive during the time when the pointer 34 is in contact with the segment 35. Thus the higher operating pressure will be applied.
