422,444. Syringes. KERMODE, H. T., 35, Haslingden Drive, Toller Lane, Bradford. March 13, 1934, No. 7871. [Class 102 (ii)] In a syringe auxiliary ports 9 are uncovered on the suction stroke by a sleeve 4 having a coned valve end engaging a seating 5. The valve moves in a cylinder 7 integral with the end cap 8, movement of the valve being limited by a screwed bush 10. The passage 6 through the valve is of Venturi form and the mouths of the passages 2, 11, in the nozzle and bush 10 are flared. The piston-rod 17 is connected to the piston 14 by a ball joint 16.
