Abstract: 394,484. Sampling pulverulent materials. JORGENSEN, M. VOGEL-, 24, B³lowavej, Frederiksberg, near Copenhagen. June 14, 1932, No. 16851. [Class 58.] In a mixing plant for pulverulent materials in which the materials are mixed in hoppers by means of stirrers and compressed air, a sampling hopper is provided, fed simultaneously with the mixing hoppers, whereby the composition of the materials fed to the latter may be ascertained ; by this means continuous o-peration of the mixing devices for the main hoppers is avoided, and the composition may be controlled. In the form shown, a hopper 1, in which the materials are mixed by stirrers 3 and air blasts 2, is fed from a conveyer 5 through a distributing device 6 which also feeds the sampling hopper 1<1> provided with similar mixing means. Both hoppers discharge into a conveyer 9, control valves 8, 8<1> being provided. The distributing device comprises an inclined shoot rotating about a vertical axis. In another form, the conveyer 5 feeds a sampling device and two silos, without stirring devices, which discharge through a distributing device to a number of hoppers fitted with stirrers and air blasts.

Title: Improvements in or relating to apparatus for weighing and classifying material
IPC: B07C5/18
Filed: 1938-06-07
Abstract: 506,102. Sorting by weighing. GRAF, J. E., and LAMOREE, J. K. June 7, 1938, No. 16876. [Class 143] An apparatus for weighing and classifying strip or other material comprises a conveyer mounted on a weighing device which is operated whilst the material passes along the conveyer, and classifying means operable by the weighing device to sort the material according to its weight. The sheets A to be sorted are passed singly through rotating cylinders 116, 123 and are carried by belts 117 to the weighing platform of a scale 10. The weighing platform comprises a number of freely rotatable discs 25 constituting a conveyer down which the sheets pass by gravity and from which they are removed by endless belts 50 and rotating cylinders 32, 56. Sheets of over or under weight cause the scale beam 12 to assume a position below or above the horizontal and rock a contact lever accordingly to close, the circuit of one or other of two solenoids. The solenoids actuate deflectors 162, 163 so as to set them either in the position shown in order to deflect the light sheets to a stand B, or in a depressed position to deflect the heavy sheets to rotating cylinders 58, 62 and thence by conveyer belts 99 to a stand D. Sheets of normal weight fail to displace the contact lever and the deflectors 162, 183 both remain in an horizontal position and allow the sheets to pass between them after which they are carried by belts 71 to a stand C. The tolerance allowed between normal and light or heavy sheets may be determined by screw adjustments co-operating with the contact lever. The vertical position of the weighing platform 25 may be adjusted by a hand wheel 5.
