Title: Discharge control of chute outlets
IPC: B65G69/00
Filed: 1959-10-26
Abstract: 932,115. Automatic level control. SCHUCHTERMANN & KREMER-BAUM A.G. FUR AUFBEREITUNG. Oct. 26, 1959 [Nov. 8, 1958], No. 36254/59. Class 38 (4). [Also in Group XXX] Pivoted feeler G senses the flow of coal from charging shoot H into spiral shoot W and controls the position of pivoted discharge flap F so that the spiral shoot remains substantially full of coal irrespective of the input whereby abrasion is minimised. Feeler G operates control switches A, B, which control electric actuator L which operates flap F, which in turn operates control switches C, D. Circuit operation (Fig. 2). Input increasing.- When shoot H is full and the coal begins to pile up in the charging shoot H, feeler G is caused to pivot to a part-open position. This actuates switch A which moves contact a to a 1 , d being closed; this actuates time relay Z 1  which operates contact Z 1 : this actuates opening relay M A  which operates electric actuator L. This half-opens flap F. If the coal continues to pile up, feeler G is caused to pivot to a full-open position. This actuates switch B 1  which moves contact b to b 2 . This actuates relay Z 1  (as before) and consequently operates actuator L to full open flap F. The actuator simultaneously opens contact e 1  to break the circuit and to leave the flap fully opened. Input decreasing.-The full opening of the flap (see above) additionally actuates switch C and thus closes contact c. Hence, if the level of coal decreases, feeler G drops to the half-open position and in so doing, actuates relay Z 2 , which operates closing relay M 2  which causes actuator L to move flap F to the half-open position. Similarly, if level of coal further decreases, feeler G moves to the closed position and again operates closing relay M 2  and brings flap F to the final closed position, and this completes the cycle. Height control of shoot W (Fig. 1).-The height of the spiral shoot W is controlled by feeler T, positioned at the bottom of the shoot. When the discharged coal piles up it displaces feeler T which actuates switch E which causes the spiral shoot to be elevated above the level of the discharged coal.

The left - hand margin stop X, Figs. 1 and 2, slides on a stop-rack 7, on the carriage 5 and contacts with a centrestop 10, mounted on the frame-work. The stop comprises a s h e e tmetal frame a, to which is pivoted a latch c by means of a spring d, Fig. 8 through which passes a screw 19. The stop is provided with a cam-member e, having two upstanding fingers 27 between which passes a tail 17 on the latch c. The member e is adjustably mounted on the frame by a screw 28 and slot 25 and is guided by lugs 26. A pointer f, arranged over a scale 9 on the front of the rack 7, is adjustably mounted on the stop. The frame is provided with a centre-stop camming-lug 13. The screw 19 passes through a slot 20 in the latch c so that, when the latch is depressed by a finger-piece 14, to disengage its nose 15 from the rack teeth, it is simultaneously slidden longitudinally relatively to the frame by the interaction of its shoulders 17<a> and the cam-fingers 27. The latch is guided in this movement by depending lugs 16, and by the fingers 27 and tail 17. The stop may then be pushed along the rack 7 until a screw 12 mounted in a spreaded collar 11 on the frame engages with the centre-stop 10. The latch is then released to engage the rack and, due to the previous sliding movement, the screw 12 is set a predetermined distance away from the centre-stop. The frame a for the stop is manufactured from a blank i, Fig. 9, by a series of bending opertions which may be performed on a power press. The blank i is first bent at rightangles along the lines 38, 39, 40, the end of the long arm 36 is bent slightly outwards, and the arm 37 is bent inwards along the line 37<a>, the arm 36 is bent completely round to form a loop, the arms 34, 35 are bent upwards along the lines 44, the loop is bent backwards first about the line 48 and then the line 49, the camming lug 13 is bent upwards, and finally the loop is brazed to the side of the box-like frame thus formed and is internally threaded to receive the screw 12, as shown in Fig. 8. Specification 428,330, which describes a right-hand stop, is referred to.

Abstract: 899,361. Thermionic converters. THERMO ELECTRON ENGINEERING CORPORATION. Nov. 14, 1958, No. 36753/58. Class 39(1). In a process of converting thermal energy into electrical energy, one of two electronemissive surfaces 10, 12, Fig. I, maintained in closely-spaced side-by-side relation, under a vacuum of at least 10<SP>-5</SP> mm. of Hg, e.g. in steel container 17, is heated to a temperature of at least 600‹C. while the other is maintained at a temperature at least 300‹C. below, so that under the influence of crossed magnetic and electrostatic fields, set up by use of magnet 22. and an anode 16 parallel to the emissive surfaces, electrons flow from heated surface 10 to surface 12. A small portion of the power output of the device, obtained across load 26, may be used to create both the electrostatic and magnetic fields. In a further embodiment a plurality of hot plates 31-33, Fig. 2, of increasing width are arranged adjacent cold plates 36-38 of decreasing width. Associated with each plate is an anode of corresponding dimensions, positive potentials of increasing magnitude being applied to anodes of increasing width. Any number of hot plates and an equal number of cold plates may be used, depending on the power output required. Heat may be obtained from nuclear or solar sources or by burning oil, coal or natural gas or from A.C. or D.C. current. Suitable electron emissive materials are oxides of barium, strontium, calcium or lanthanum; thoriated tungsten thoria; a mixture of barium and strontium oxides covered by a sintered tungsten layer; pure tungsten; a molybdenum housing filled with granules of a fused barium oxide and aluminium oxide mixture; or a perforated molybdenum housing containing sintered thorium oxide. The hot plates are maintained at temperatures between 600‹C. and 1600‹C. depending on the materials used. The anodes may be of steel, copper or silver. To eliminate end-loss anode current due to electrons collected by anode 48 hot plates 171-176, Fig. 5, and cold plates 181-186 may be arranged in a circle, corresponding anodes 177, 188 being arranged concentrically therewith. The circuit connections are similar to those shown in Fig. 2. As shown in Fig. 5, three banks A, B, C of electrodes are arranged between heat insulators 191 within a cylindrical housing 161. Two groups of heat conducting rods 187, traversing the hot and cold plates respectively, communicate with headers at the ends of the housing, heating and cooling fluids being circulated through the respective headers. A coil 192 surrounds the housing to provide an axial magnetic field. In a further modification the hot and cold plates are in the form of cylinders surrounded by their associated anodes.
