Title: Combination of tractor and implement
IPC: A01B63/22
Filed: 1972-12-20
Abstract: 1366179 Combination of tractor and implement FORD MOTOR CO Ltd 20 Dec 1972 [27 Dec 1971] 58912/72 Heading A1P A tractor and implement combination having power lift and drive line torque control is characterised by having a hydraulic series with the tractor lift cylinder a second cylinder 17 controlling the height of the gauge wheel 15 attached to the implement, the two cylinders thus operating in unison. The tractor lift cylinder 19 moves the draft links 27 when the valve 30 is opened or closed by the handlever. Position feedback is provided by the rockshaft cam 34 and links 32 and 35. The position of the draft links is also affected by the drive line torque sensor 31 which controls the valve 30 via links 28, 33, 32, 35 and 36. With the valve 40 in the position shown in Fig. 2, the implement cylinder 17 is connected in series with the tractor lift cylinder 19 so that oil passes from the pump 29, through valves 30 and 40 to the left hand side of cylinder 17 to cause the piston 37 to move to the right and lower the gauge wheel 15 with respect to the implement frame 16. Oil from the right hand end of the cylinder passes through valve 40 to the tractor lift cylinder 19 to lift the draft links 27 via push rod 24, levers 22, 25 and link 26. When the valve 30 is reversed, the spring 41 lowers the draft links and causes the oil flow to reverse so that pistons 20 and 37 move to the left, the latter causing the implement gauge wheel 15 to lift relative to the implement frame 16. In order to ensure long term synchronisation between the two cylinders, the volume of the implement cylinder 17 is somewhat smaller than that of the tractor lift cylinder 19 and the push rod operated valve 39 in the piston 37 allows oil to flow past the piston when it has reached the end of its stroke. Movement of the spool of the valve 40 to the left causes the implement cylinder to be isolated from the circuit controlled by valve 30. The relationship between drive line torque and cylinder movement may be altered by varying the position of the pivot at the end of lever 35 along the length of the floating lever 32. The implement may be attached to the draft links rather than to the tractor frame so that both the front and rear of the implement will be powered vertically.

Patent GB-2040492-A (GB)
Title: Method and Composition for Treating Contact Lenses
IPC: G02C7/04
Filed: 1980-01-02
Abstract: The invention relates generally to a method and composition for the treatment of contact lenses, especially silicone and hydrophilic plastic contact lenses, to remove inorganic deposits and to prevent the formation of inorganic deposits on the lenses. One of the problems connected with these types of lenses is the formation, over a period of time, of insoluble inorganic deposits on the lenses. These deposits are thought to be primarily calcium based, e.g., calcium phosphate and calcium carbonate, but may also contain other inorganic materials and associated organic materials, e.g., protein. The presence of these insoluble inorganic deposits is a common cause of lens intolerance and decreased visual acuity. The method comprises contacting a contact lens with an aqueous solution containing an effective amount of a polymetaphosphate, gluconic acid or salts thereof as sequestering agent for a period of time sufficient to remove existing inorganic deposits and to prevent formation of inorganic deposits. The solution may be a preserved saline solution containing 0.01-20% by weight of the sequestering agent.
