Title: Apparatus for transferring coal and the like from a mine shuttle car to a conveyor
IPC: B65G65/44
Filed: 1946-11-19
Abstract: 626,675. Endless-belt conveyers. JOY MANUFACTURING CO. Nov. 19, 1946, No. 34280. Convention date, Dec. 19, 1945. [Class 78 (i)] An apparatus for transferring coal from a mine shuttle car to a conveyer comprises a coal-receiving bed, an inclined trough attached to the front end' of the bed, an endless conveyer travelling forward along the centre of the bed and up the trough, trackways for the front wheels of a shuttle car extending along both sides of the lower section of the conveyer, and means normally disposed at the rear end of said trackways and adapted to be pushed forward over them by said car for pushing coal therefrom onto the conveyer. The coal receiving bed, mounted on a low skid frame 1, Figs. 1 and 2, has wing plates 3 disposed on either side of and above a central plate 2 along which push plates 12, attached to endless chains 11, are traversed. The chains 11 which pass over idler sprockets 13, under shoes 21, up a trough 6, the inclination of which may be adjusted by a iack 8, and over sprockets 14, which are driven through gearing by a motor 19, convey coal from the plate 2 onto a belt conveyer 22. An even flow to the conveyer 22 is maintained by plates 50, Figs. 1 and 6, which also put a crown on the pile of coal being carried up the trough. Coal is dumped onto the plate 2 from shuttle cars each of which runs up ramps 4, and along plates 3 with its front wheels engaged on plates 36 between the wheels 29, 31 of a carriage which is moved along rails 33 by the rear driving wheels of the car, and which is fitted with ploughs 37 and scrapers 41 which clear the plates 3 and rails 33 of coal spilled by the previous car. In passing on to the plates 36 the front wheels of the car pass over a pair of vanes 42, Fig. 5, which are horizontal when the carriage is at the rear end of the bed, and when supporting said car wheels lock said carriage in its rearmost position, said vanes being rigidly attached to a shaft 43, to which is also secured rollers 46 extending through slots in the plates 3 and engaging inclined guards 47. The arrangement being such that on forward movement of the car and carriage, rollers 46 roll up inclines 47 and along plates 3 so rotating the shaft 43 and engaging the vanes 42 behind the car wheels so locking the wheels to the carriage until the end of its return movement. In a modification two different types of pairs of plates 50 are described.

Title: Improvements relating to constant current-variable voltage electric generating systems
IPC: H02K23/40
Filed: 1930-11-15
Abstract: 362,631. Constant-current generators. AUSTIN, G., 10, Calderwood Road, Newlands, MACFARLANE, J. C., Braehead, and MACFARLANE, W. A., Alderwood, both in Cathcart, both in Glasgow. Nov. 15, 1930, No. 34434. [Class 35.] Exciting; cores ; commutators. -A constant-current generator A has an exciter E capable of giving a voltage several times higher than that required to provide full load excitation of the generator and having a magnet system of low reluctance energized by a winding G separately excited at constant voltage opposed by a winding H carrying the generator current or a current proportional thereto, and the exciter field windings are of as small a number of ampere-turns as possible. The number of ampere-turns in these windings is normally only slightly different so that under transient conditions a slight change of the dynamocurrent causes a large change of excitation. The exciter magnet system is laminated, and the main dynamo poles may be arranged so that the air gap tapers from the trailing pole tip to the leading tip. The main generator may have high-resistance commutator connections and its magnet system may be laminated. Specification 347,359 is referred to.

Title: Improvements in gas turbine power plants of the continuous combustion type
IPC: F02C7/08
Filed: 1937-12-13
Abstract: 507,332. Gas turbines. AKTIEBOLAGET MILO. Dec. 13, 1937, No. 34514. Convention date, Dec. 16, 1936. [Class 110 (iii)] In a gas turbine, the working medium is reheated-between stages by hot gas passing from the generator to the high-pressure stage inlet. In the embodiment shown in Fig. 1, air from a compressor 16 is pre-heated by the exhaust gases in a regenerator 9 and passes into a shell 21 surrounding a combustion chamber 20. Fuel, such as coal, is supplied through the valved pipe 22 and air enters from the shell through holes 27. Combustion products pass to the turbine by a pipe 28, 29, 2 and additional air by a pipe 32. Part of the combustion products may pass through a reheater 4 before reaching the pipe 2. The valve 34 in the pipe 29 may be controlled manually or automatically in response to the useful load, the pressure in the pipe 29 or the pressure of the compressed air. The valve 33 in the pipe 32 may be controlled automatically in response to the temperature of the gases in pipe 29. The pipe 32 may surround the pipe 2 so that the admixture of the combustion products and the extra air takes place just prior to admission into the turbine. The flow of combustion products through the heat-exchanger 4 is independently controlled by a thermostat and valve 39, 41, 38 in response to the exhaust temperature or, it may be, the temperature in the low-pressure stage inlet pipe 6. The valve 38 may be mechanically connected to the valve 34. The main control of the plant may be by varying the number of stages in the air-compressor, by throttling the air-compressor or by blowing-off excess of air. For over-loads, combustion products may be introduced at 37 into the pipe 6 being completely burnt there and mixed with the gases coming from the high-pressure stage. A similar plant is shown with three stages and two inter-stage reheaters in parallel responsive, respectively, to the temperatures of the intermediate stage inlet and the final exhaust. These are arranged so that, on diminishing load, the reheater before the lowpressure stage is put out of operation first. A pipe is provided for permitting compressed air to byepass the shell 21.

Abstract: 473,453. Impedance networks. STANDARD TELEPHONES & CABLES, Ltd. Dec. 18, 1936, No. 34856. Convention date, Dec. 18, 1935. [Class 40 (iii)] An electromechanical filter section comprising elements, for instance, of the stretchedwire type, is combined with a purely electrical section for the purpose of reducing the fixed loss in the pass band, widening the pass band, lowering the impedance level and providing a flexible choice of attenuation characteristics. The input and output terminals of the two sections may be connected in series or in parallel. The theory is explained in general terms with reference to Figs. 1 to 5 (not shown). In a band-pass filter, Fig. 6, an electromechanical section comprises mechanical springs and masses, Fig. 7 (not shown), represented by M1, K1, K2, and electromechanical transducers represented by force factors G and resistances Re, in the manner explained in Specification 453,748. The electromechanical section is equivalent to a lattice, Fig. 9 (not shown) ; the electrical section, after its impedance level has been transformed to allow for the transducer elements G, is equivalent to another lattice, Fig. 8 (not shown) ; and these two lattices in combination are equivalent to the single lattice shown between the terminals 1, 2 and 3, 4, Fig. 10. The design procedure is (1) to determine the arms of the latter lattice from the prescribed image impedance and attenuation characteristic ; (2) to divide each arm into two parts realizable respectively in terms of electrical and electromechanical elements ; (3) to deduce the two lattices, Figs. 8 and 9 (not shown), which in combination are equivalent to the original lattice and correspond to these two groups of elements ; and (4) to deduce the two equivalent ladder networks, Fig. 6. Another embodiment of the invention is shown in Fig. 13, and comprises a magnetic receiver having two windings and a magnetic armature 'and represented by self-inductance L1, mutual inductance ŒM, and mechanical mass and stiffness M2, K2. The electrical section comprises condensers. S1, S2, and by giving finite or limiting values to the parts M, S1, S2, a suitable band-pass, high-pass or low-pass composite filter can be designed. Another embodiment is shown in Fig. 15. According to the Specification as open to inspection under Sect. 91, the electrical section may comprise a simple shunt resistance. This subject-matter does not appear in the Specification as accepted.
