Title: Improvements relating to electric relays
IPC: B61L23/12
Filed: 1940-10-08
Abstract: 560,079. Electromagnetic switches. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Oct. 8, 1940, No. 14999. Convention date, Nov. 16, 1939. [Class 38 (v)] The fixed contacts of an electromagnetic switch are adjustable in three directions. The electromagnetic switch may have contact mechanism associated with different types of electromagnetic driving mechanism so that it can function as a self-interrupter, an ordinary relay, or a relay responsive to current of one polarity only. The contact mechanism comprises an insulating rocker 15 suspended at its ends by two strips 16 and carrying pairs of spring contacts 18, 19 adapted to engage fixed contacts 18a, 19a. Each fixed contact comprises a screw which screws into a bracket 26 that is both rotatable about and slidable along a post 27 for adjustment purposes. The figure shows an interrupter in which the rocker 15 carries a spring 35 carrying an armature 34 which acts as a pendulum bob and is attracted towards the poles of an electromagnet 30a. The rocker 15 carries two additional contacts similar to 18, 19 but which normally engage their fixed contacts and the circuit to the electromagnet is in series through these two pairs of contacts. Attraction of its armature by the magnet will break its circuit at one pair of contacts but momentum will cause some further swing of the armature and then a return movement of it to the other side, which will-not be prevented by the temporary reclosing of the electromagnet circuit. Thus continual interruption will occur at a rate determined by the oscillating characteristics of the 'pendulum armature. A rectifier R is placed in parallel with the electromagnet. When the device is used as an ordinary relay, a spring biases the contacts 19 into engagement with their fixed contacts 19a.

Title: Process for manufacturing metallurgical coke
IPC: C10B53/08
Filed: 1966-04-06
Abstract: Metallurgical coke is made from raw petroleum coke particles, or from a blend of particles of raw petroleum coke and bituminous coal, optionally with an inert carbonaceous material (e.g. anthracite, calcined petroleum coke or coke breeze), in a two-stage heating process.  In the first stage, the charge in the form of a thin stream is rapidly heated to a temperature in the range 300 DEG  to 525 DEG C. and while still in that range the particles are pressed at 500 to 4000 p.s.i.g. to produce a green body which, while still hot, is heated rapidly in the second stage to 560 DEG  to 1000 DEG  C. to reduce the volatile content. If petroleum coke alone is used, the volatile matter content (VMC) should be at least 10% b.w., and the coke must form a hard "button" while being heated, in accordance with A.S.T.M. D271-48; if used with coal the VCM must be at least 8% b.w., the coal having a VCM of at least 15% b.w.  Proportions of the blend are (parts per hundred):  20 to 95 petroleum coke, 80 to 5 bituminous coal, and 0 to 25 inert carbonaceous material, and particle sizes should be less than 1/8 inch.  Heating times are of the order of 40 seconds to 5 minutes for the first stage and 1 to 8 hours for the second, and the first stage may comprise a duct through which the particles are carried by combustion gases from a furnace, and/or a chamber containing a vibrating tray or moving grate or belt also heated by the gases.  Heating rates are given for the second stage. Specific examples are described.

Abstract: 744,262. Velocity modulated tubes. SPERRY CORPORATION. June 5, 1953 [July 14, 1952], No. 15565/53. Class 39 (1). A klystron having at least one resonator, preferably of the reflex type, is tuned by screw 60 acting via levers 52 and 43 on tube 39 secured to a flexible wall of the resonator; one bearing surface at 54 or 58 is fixed while the other bearing surface 58 or 54 moves along the lever 43 or along abutment 55 as tuning screw 60 is adjusted, and the arrangement is such that the non-linearity of axial movement due to the lever linkage compensates for the non- linear variation of frequency with movement of the flexible resonator wall so that an approximately linear relationship is obtained between movement of tuning screw 60 and change in resonant frequency of the resonator. The axial movement of rod 39 may be 1/50 that of tuning screw 60. The spacing between reflector 16, which may be a rod carrying a projecting concentric sleeve, Fig. 3 (not shown) and the resonator grid 36 remains unaltered during the tuning. The actuating mechanism for the tuning rod 39 comprises U-shaped cantilever 43 carried on seats on two members 45 (only one shown) at its two ends and having a spring support 56 at its mid-point, and lever 52 supported by ball 58 from cantilever 43 and by two balls 54 (only one shown) from fixed member 55 so that it can pivot about the common axis of balls 54. Ball 58 is soldered to lever 52 and balls 54 to member 55. Externally actuated screw 60 has ball 62 soldered thereto through which it exerts pressure on extension 63 of lever 52 against the pressure of mouse trap spring 67. An aperture 64 provides clearance for nut 48, collar 68 acts as a stop for the downward movement of lever 52 to prevent damage to the resonator; while upward movement is prevented when the right-hand end of lever 52 contacts cantilever 43. In an alternative construction there may be one ball between 52 and 55 and two balls between 43 and 52, in which case 54 moves along the surface of 55 and 58 is fixed. 13 is a smoother grid and resonator grid 34 extends across the smaller end of conical aperture 18. Rod 39 is restrained against lateral movement.
