[Class 58.] An apparatus for treating grain comprises a drum 5 forming a treatment surface for exerting a husking, scouring or polishing action on the grain by co-operation with a plurality of beater elements 1 inside the drum and arranged in juxtaposition side by side on shafts 3 in a series of rows parallel to the axis of the drum, the working portions of the beater elements on each shaft forming collectively a yieldable beating surface, the elements being adapted to swing unhindered about the shafts and the width of the elements being substantially equal to the length of a grain under treatment. The elements are formed with eyelets, by means of which they are mounted on the shafts, and comprise one or two rectilinear or curved shanks. When two shanks are provided, they may be parallel or inclined and of equal or unequal lengths. The elements may be of wire of round cross-section or of flat sheet metal, rubber or leather, of square, rectangular or oval cross-section. The eyelets may be enlarged to prevent rubbing of the shanks. When flat elements are employed they may be arranged parallel to the direction of flow of grain through the machine, or alternate rows of elements may be respectively parallel and inclined thereto, the angle of inclination being acute or obtuse, or all the rows may be inclined, alternate elements being inclined in opposite directions. Alternatively, the elements may be formed as rings freely mounted on the shafts, the diameters of alternate rings differing : the rings may be of round, oval or triangular crosssection and of circular, oval, triangular, or polygonal contour.

Abstract: 180,285. Murray, T. E., (Assignee of Rypinski, A. B.). Jan. 20, 1921, [Convention date]. Riveting; joints.-In riveting a copper-coated steel plate or other metal article B to one A of glass, cement, porcelain, wood, rubber, fibre or other non-metal by a rivet which is heated and upset by electrodes, the current density is maintained greater in the projecting shank than at adjacent points preferably by reducing the cross-section. A hollow copper rivet C is inserted with its head against the metal plate B and the projecting end D is engaged by an electrode G having a central pin H. Owing to the reduced cross-section of the rivet shank and to the cooling effect of the electrodes and plates only that part of the projecting shank adjacent to the place &c. is softened and upset so that the plates are not damaged and the extreme end of the shank may retain its original form to serve for an electric contact, an electrical or mechanical connection &c. The section may be reduced in other ways and other cooling means may be used.

[Also in Group XL (b)] The signal/noise ratio in a pulse radar receiver is increased by combining the IF echo pulses with similar pulses delayed by the recurrence period or an integral multiple thereof. As shown, the EF echo pulses at terminal 1 are applied alternately to two such loop circuits IF1, D1, A1 and IF2, D2, A2 by means of switch S1, the output from any one circuit being applied to the remaining stages R of the receiver by means of switch S2 when terminal 1 is connected to the input of the other circuit. When a P.P.I. display is employed, the period of switches S1, S2 is preferalby equal to the time taken for the radio beam to sweep through its angular width. Each loop circuit comprises an IF amplifier, a mercury delay line D and a positive feedback loop including an amplifier A. The two delay lines are mounted in a common housing and when the invention includes means for discriminating between fixed and moving targets by means of a further delay line included in stage R, all three lines may be in a common housing. The switches S1 and S2 each comprise two cathode followers whose cathodes are connected respectively to the anodes of a cathode-coupled pair of valves having a common pentode cathode impedance, Figs. 2 and 3 (not shown). The input(s) are applied to the grids of the cathode followers, the output(s) are taken from the cathodes and the switching waveform is applied to the cathode-coupled valves.
