Abstract
754,497. Shoots. AKTIEBOLGET LINDEROTHS PATENTER. July 8, 1954 [July 9,1953], no. 20028/54. Class 78 (1). A device for discharging powdered material by gravity against an increase of air pressure comprises a vertical nozzle 1 which has at its lower end a sleeve 2 of soft, flexible or pliable material such as synthetic rubber or the material known as " Teflon." The sleeve is formed of a number of flat sheets joined together along their longitudinal edges by vulcanization and has a fold 3 on each of two opposed sides to facilitate collapse. The thickness of the sleeve may decrease towards the outlet or it may be made of thin material of uniform thickness which is provided with stiffening or stretching means to prevent it being sucked into the nozzle.
