Abstract: 532,493. Gyratory crushers. BROWNING, R. E. Sept. 1, 1939, No. 25087. [Class 59] A crusher for pulverizing rock or like material comprises an outer annular stationary member with its axis vertical, an inner annular member arranged within and spaced apart from the outer member, and means for mounting the inner member for free rotation about a gyrating axis which intersects the axis of the outer member at a point below the crushing zone. The device comprises a vertical sleeve 7 having its upper portion shaped to form a spherical bearing surface 9, and a shaft 11 centred within the sleeve by bearings. The lower portion of the shaft rotates about a central vertical axis 15 while the upper portion of the shaft comprises a cylindrical portion 18 the central axis of which, 19, is inclined to the axis 15 and intersects it at a point 20 which is the centre of curvature of the surface 9. The inner annular member 21 comprises a crushing-head 24 secured to a liner 22 which rotates about the part 18 of the shaft 11 and has a spherical surface 26 which seats on the surface 9 Thus the head 24 is free to rotate relatively to the shaft 11 about the axes 19, and rotation of the shaft causes the head to gyrate about the point 20. The outer annular member A comprises a conical mantle . 62 secured to a carrier 63 which is mounted on the frame of the device coaxial with the axis 15. The member has a screwed outer surface 66 by means of which the distance between it and the member 21 can be adjusted. The upper part of the carrier forms a hopper 89 for the reception of the material which is crushed by passing through the space B between the mantle 62 and the gyrating head 24. The member A may be secured to the frame by bolts 73 surrounded by springs 74 to allow the mantle to move relatively to the frame when non- crushable material enters the space B. The mantle assembly may also be hinged to the frame to allow it to be swung to one side for cleaning or other purposes. The bearings and bearing surfaces 9, 10 are lubricated by oil circulated by a pump. In a modified construction, the crusher head 24 is supported by a shaft which is journalled in an inclined bore of a bushing that is rotated by the drive.

Title: Improvements in or relating to electrical testing arrangements including cathode ray oscillographs
IPC: G01R27/32
Filed: 1937-09-17
Abstract: 504,179. Oscillographs ; frequency measurements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 17, 1937, No. 25295. Convention date, Sept. 17, 1936. [Class 37] [Also in Group XL] A resonance testing arrangement comprises a cathode-ray oscillograph and an oscillator, the output frequency of which is varied periodically by' a relaxation oscillation generator in both directions with respect to the resonant frequency of the circuit under test, the current supplied from the oscillator to the resonant circuit being employed to control the cathode beam. The resulting graph is a pair of resonance curves which when superposed can be employed for, indicating correct alignment of circuits under test, lack of symmetry in the curves denoting the amount of adjustment required, or, depending upon the sweep frequency, a pair of curves which are mirror images of each other can be produced side by side. In Fig. 3, the oscillator 41 has a tuned grid circuit 45, 47, 49, its output circuit 51 including variable capacitances 53, 57 and phase correcting resistor 55. The capacitance 57 produces a leading phase displacement of 90‹ in the output current which is fed to the grid of a frequency control tube 61 in which a further phase change of 180‹ occurs, so that the output current of the tube 61 lags the output of oscillator 41 by 90‹. This lagging current is supplied to the circuit 45, 47, 49 and is equivalent to an inductive shunt. The frequency control tube 61 is also supplied with current having a triangularly peaked waveform which gives a linear characteristic to the frequency change. The peaked wave-form is equilateral in shape and is obtained by a pentode 65 having its grid and anode energized from secondary winding 67, condenser 79 being discharged through resistor 81 which is connected to the input of tube 61. Biassing resistor 77 determines the symmetry of the peaked wave. Coupling at 45, 83 feeds the oscillatory currents to a mixing tube 87, and the oscillatory section of this tube can determine the single frequency about which the test current frequencies vary. Terminals 93 provide a connection for the synchronizing sweep circuit which has a periodicity twice that of the peaked wave. Two traces for upward and downward variations of frequency are thus made, the characteristics of the tested circuits being identical, or the tuning of a single circuit determined, when the traces are exactly superposed. Vol. 79, No. 476, of the Institute of Electrical Engineers Journal, pages 194-200, is referred to.

Filed: 1958-08-07
Abstract: 846,190. Mixing appliances. DU PONT DE NEMOURS & CO., E. I. Aug. 7, 1958 [Aug. 15, 1957], No. 25416/58. Class 86 [Also in Group XX] A method of mixing by bringing two (or more) centrifugally formed upwardly concave films into interfacial contact may be performed by means of vertically coaxial hollow inverted conical vessels 1, 2 rapidly rotatable by shafts 6, 8 driven by motors 7, 9 respectively. Fluid is supplied to vessel 1 from container 13 through duct 12 and to vessel 2 from container 14 through duct 15 and the hollow shaft 8. The fluid in vessel 1 flows in a thin film over the rim 3 (which is in close proximity to the inner surface of vessel 2) making contact with the film of fluid flowing up the wall of vessel 2. The mixed fluid flows over the rim 5 of vessel 2 into the container 17. A constructional embodiment of the apparatus shown diagrammatically in Fig. 1 is described with reference to Fig. 2 (not shown). The method is stated to be applicable to liquids, emulsions, dispersions, finely particulate solids and materials which can be rendered fluid by heating. In the case of liquids of different viscosity, the more viscous liquid is rotated at the greater speed. By using a suitable number of vessels more than two materials may be mixed. The rotating vessels may be cones, discs, cups or other suitably concave vessels; they may be provided with vanes or baffles, and the inner vessel may be perforated. The vessels may rotate in the same or (if turbulence is required) in opposite directions. The axis of rotation is preferably but not essentially vertical. The flow of materials may be automatically controlled by a characteristic of the effluent. The surface exposure of each material to the other may be increased by increasing the speed of rotation to reduce the thickness of the layers. The method and apparatus as well as being suitable for physical mixing are especially suitable for chemical reactions where the intimate contact between and constant concentration of reactants and defined area in which reaction takes place result in small particle size, suppression of unwanted side reactions and possibility of performing reactions which have critical reaction rates. The method and apparatus are claimed as especially suitable for the preparation of emulsions for photographic film, among other named uses.
