Abstract: 494,117. Ventilating granaries, ships' holds, and silos. LITTMANN, L., STRUB, T., and MAHO, J. A. A. May 10, 1937, No. 13310. [Class 137] In the ventilation of goods stored in bulk, such as grain, which allow of the passage of air, flues f leading into vertical stacks a, b, c; d are provided in the material for the admission or evacuation of air and arranged to define zones of parallel-piped shape, which may be juxtaposed. In Figs. 1 and 2 is shown a single zone with two horizontal flues f each communicating with vertical stacks a, b supplied with air from a pipe s and having pistons h movable by a cable m to open or close the passage of air from the source s and stacks a, b to the flues f. Each of the stacks serves at will either for supplying air to, or for evacuation of air from, the mass of grain. By this means, the direction of the currents of ventilating air are changed to ensure full ventilation of the mass. Figs. 3 and 4 show the arrangement of flues in silos of considerable height divided into superposed zones. The stacks a, b may be used alternately for inlet and evacuation, and stacks c, d for evacuation only, the stacks a, b being provided with the pistons h controlling the air supply. Flues f serve either as inlet and evacuation flues, and flues e as evacuation flues only. Lateral air passages g form shunt passages which permit air to reach the top of the stack when the piston is at the level of the shunt passage. Valves p control the passage of air into one or other of the stacks a, b. Fig. 7 shows in horizontal section the arrangement of flues and stacks for a group of contiguous units of a silo.

As described the steps are performed on a boron or aluminium-doped P-type silicon layer epitaxially grown on a silicon, sapphire, or spinel substrate. The getter preventing layer is of pyrolytic silicon nitride, the gettering layer and insulating material of thermal oxide and the windows are formed by etching through a photoresist mask. The gate electrode may be of molybdenum or polycrystalline silicon and all the electrodes of aluminium. As shown in Fig. 8 the gate electrode may extend over the thicker layer to one side of the channel proper without detrimental capacitive effects.

[Also in Division A2] The pneumatic aerating floor of an installation, e.g. a silo or hopper, in which a powdery or fine-grained material such as flour is subjected to homogenizing, discharging, conveying or like operation involving movement of the material, comprises a plurality of adjacent aerating boxes covered by air-permeable, porous plates, and, within each box, a backflowchecking safety device consisting of a straight, curved or spiral length of air-permeable, flexible tubing, which is closed at one end and connected, at its other end within the box, to a supply of compressed air. Each aerating box, Figs. 1 and 2, may comprise a shallow dished body 1 covered by a bolted-on porous plate 7, and an air-permeable flexible tube 2, e.g. made of cotton, curled within the body. The end 6 of the tube is closed and its other end is connected, through a nipple 4, to a pipe 3 supplying compressed air. If the plate 7 breaks, material pours through the fracture and squeezes the tube 2 flat, and is thus prevented from passing into the pipe 3.

Title: Improvements in rotary converter, and motor generator voltage regulation methods
IPC: G05F3/04
Filed: 1932-05-13
Abstract: 401,671. Automatic regulation. TIMBERLAKE, E. J., Lulworth, Pickhurst Rise, West Wickham, Kent, and ELECTRO DYNAMIC CONSTRUCTION CO., Ltd., Devonshire Grove, Peckham, London. May 13, 1932, No. 13751. [Class 38 (iv).] A voltage-regulation arrangement for a rotary converter or motor generator S fed from a D C circuit of variable voltage consists in connecting a condenser C in series with a resistance B having a high temperature coefficient (e.g. a barretter) across the generator S, the load V being connected across the condenser. The machine S is designed so that a small variation in the d.c. voltage produces a large variation in the speed and therefore in the frequency of the a.c. output. If the d.c. voltage rises the current taken by the condenser C increases since the frequency increases. This current increases the voltage drop across the resistance B to maintain the voltage across the load V constant. Resistances may be connected across and in series with the condenser C to enable initial adjustments to be made.
