Filed: 1954-03-05
Abstract: 739,843. Pneumatic conveyers. DANSMIDTH CORPORATION. March 5, 1954 [March 11, 1953], No. 6545/54. Class 78 (1). Pulverulent material stored in the chamber 12, Fig. 1, after being rendered fluent by gas passed through the porous bottom plate 20, passes into the cylindrical chambers 31 of the rotor 28 and is blown therefrom into the conduit 33 as each chamber comes opposite to the air inlet 47. The rotor is provided with hardsurface wear plates 32 which are attached to its end plates 29 and have openings registering with the chambers 31. The intake 34 to the conduit 33 is enlarged at 34b to receive a short pipe 39, the inside diameter of which is the same as that of a chamber 31. A sealing plate 41 of kidney shape is secured to a flange on the end of the pipe 39 and is of sufficient size to cover the ends of three chambers. It is pressed against the wear plate 32 by adjustable coil-springs 43. Similar devices are provided at the opposite end of the rotor. Additional openings may be provided in one of the sealing plates to register with a pair of chambers on opposite sides of the conduit while those chambers are wholly out of communication with the conduit. In a modification, Figs. 6 and 7, a pair of screw conveyers 66, each of which is composed of flights of opposite hand, directs the material to the sides of the chamber to supply continuously the screw conveyers 74 which feed it into two chambers 31. In another modification the axis of the rotor is vertical.

Abstract: 897,492. Automatic voltage-control systems. BOSCH G.m.b.H., ROBERT. March 2, 1960, No. 7319/60. Class 38 (4). A voltage regulator of the vibrating contact type, for a shunt excited D.C. generator, has an auxiliary current limiting winding which is energized when a current limiting signal exceeds the bias on a diode in series with the winding. The field F of the generator G is controlled by contact C actuated by the voltage-responsive winding 12. A resistor 14 is connected in series with the load (together with a diode 16 which replaces the cut-out) and is shunted by the current limiting winding 11 in series with a diode 13. The current for the voltageresponsive winding 12 also passes through the winding 11, and the resulting small voltagedrop biases the diode 13 so that it does not conduct until the voltage across resistor 14, due to the load current, exceeds this bias.
