781,818. Mixing fluids in flow. BURLAGE, K. M. July 25, 1955, No. 21427/55. Class 86 In apparatus for mixing various grades of oil, disposed in containers 9, 10, with petrol, disposed in a container 13, the containers are connected by conduits 4, 5 and 6 to a distributer 3 disposed at the -top of a mixing 'chamber 1. Each oil conduit 4, 5 is closed by a manually operable stop valve, 19, 20 and a valve 61 controls the supply of petrol through the conduit 6 connecting tank 13 with the mixing chamber 1. The position of a piston 2 in the cylinder 1 determines the quantity of oil to be mixed, this quantity being varied by a control device comprising a cylinder 21 having an inclined slot 18 which is engaged by a pin 53 on the end of the piston rod 17. The cylinder 21 also carries a cam 22 which operates on a rod 23 and lever 24 for opening the petrol supply valve 61. A scale is associated with the cylinder 21. After a predetermined quantity of oil has been admitted to the measuring chamber 1, the cylinder 21 is rotated with the aid of a handle 54, causing the piston 2 to descend and uncover ports 15, 16 connecting the cylinder 1 with a collecting chamber 14. The rotation also causes the cam 22 to actuate the petrol supply valve 61 whereby the chambers 1 and 14 are filled to the desired amount. The lower end of the rod 23 is hinged to allow it to pass over the cam 22 when the cylinder 21 is returned to its original position. The mixture is discharged through a valve 63 in the bottom of the chamber 14, the valve being operated by a bowden cable 65, 66, the sheath 65 of which is attached at one end to a tube 67 and the outer end of the wire 66 is attached to a spring pressed flanged member 68. -When the member 68 is pressed, for example on to a petrol tank, relative movement between it and the tube 67 causes the Bowden cable to open the valve 63. Each holder for the oil cans 9, 10 comprises a knife-like rim 45, 46, for cutting open the bottom of the can, and a needle like projection 51 attached to toggle mechanism 48, 49, 50 for piercing the lid of the can for the supply of air.
