Patented Mar. 17, 1959 ings 22 and 24, hearing housing 20, seals 28, 30 and 32, and magent 26 permits disassembly of these parts 2,878,075 from the casing 14 as one unit.
The powder from the hopper 10 is discharged through MAGNETIC PSWDER DISPENSER the throat 15 In the sleeve 12 and the nozzle 16 into 0 Li the distributing chamber in the casing 14, to adhere to r g fi f gagfi wf fggfig i ggggf gff and build up as a layer on the rotating magnetic drum 26. signors to Union Carbide Corporation, a corporation of AS the drum rotates to a POlIlt PP Q Y one'half New York a turn, a scraper 33 removes the material from the Applicafim August 31, 1956 Serial No. 607,421 drurn and the material passes to an 1n;ec 1on chamber 2 Cl i ((1 302-51) and suspended in a stream of carrier gas.

What is claimed is: particular ob ect of the present invention 1s to prov1de 1. In apparatus for suspending in a Stream of cam-er means actuated by mmmg the hopper to adjust the gas a powdered composite material including a closed Another object is to provide a removable bearing housmaterial hopper commumcatmg at the -base wlth dissuspending gas conduit means in communication with as a package P said outlet passage for suspending said composite mate- In drawmgs: rial in a stream of carrier gas conducted therethrough,
T single figu.re Is a vemcal SFCHOH through a conveyor means rotatably mounted in said distributing netlc Powder dispenser iccording to the preferred chamber, and regulator tube means positioned above said embodiment of the present invention.
The dispenser shown comprises a hopper 10 bolted to co-nveyor mqans for (-hschargmg a ccmtmued-quamlty of mleaded i 12 ,i fi i l vertigal g in means to collect thereon a layer of said composite matei f .casmg e S are upper rial, the improvement which comprises means actuated portion In its central bore, forming a conical throat 15 as adare ovablebea' ui dtube 16 screwed Into the bottom of the central bore in 40 n n ung S ng m sald ls 2. Apparatus for suspending in a stream of carrier hopper to qquahze iheyressure above the Powder gas a powdered composite material as claimed in claim 1, with the pressure in the distributor chamber.
