Abstract: 903,477. Magnetic track brakes. BAERMANN, M. July 22, 1960 [July 23, 1959], No. 25641/60. Class 103 (1). A magnetic rail brake with magnet poles alternating in the direction of movement of the brake, as at least two ferro-magnetic polepieces 1a, 1b, &c. of triangular cross-section and serially disposed to form a body 1 which, at the equal side surfaces has magnets 5, 6 and at the base facing the rail has a braking body 2, there being between each polepiece la, 1b, &c. an air gap 37 determining the working position of the magnet arrangement. The magnets 5, 6 are embedded in slidable plates 23, 24 and the brake is enclosed by ferro-magnetic bodies 7, 8 and non-ferro-magnetic plates 9, 10, 12. The gaps 37 may be filled or partially filled with non-ferro-magnetic material 35, gaps 33 permitting expansions of members 2a, 2b, &c. forming braking body 2. The end members 30, 31 are bevelled, and the magnets 50, 51 associated with polepiece 43 being half size, no magnets being on the sides of end polepiece 44, the magnetic flux being produced by a single magnet 42. In the brake applied position, Fig. 4, the body 2 is attracted against the iron rail and due to movement of the magnet arrangement by control 39, an eddy current or hysterisis braking is also obtained. In the off position, Fig. 5 (not shown), half of two magnets having opposite polarity are situated in front of each body 1a, 1b &c. to short-circuit the magnets through the bodies and so no braking results. An indicator 22 on body 8 indicates whether the brake is on or off. In the control 39, Fig. 8, compressed air from pipe 69, 72, 74 moves piston 66 and plates 23, 24 to the right for brake release, air then flowing via opening 75 to tank 79 via valve 76. For braking the air supply is stopped, valve 76 closes and compressed air acts via bore 80 in space 59 to move piston 66 and plates 23, 24 to the left; the air in tank 79 then escapes via valve 71. On failure of the air supply the piston can be moved by a screw inserted through opening 74. Instead of sliding permanent magnets fixed electro- or energizable permanent magnets may be used.

[Also in Divisions H2 and H3] In an ignition generator, a magnet 32 with polepieces 24, 26 mounted on an aluminium flywheel 20 causes flux to pass through E-shaped core 34 on the stator to develop a voltage across coils 42, 44 Figs.2 and 3 (not shown). Further polepieces 28, 30 co-operate with a core 52 to generate a triggering voltage in coils 52, which is effective to maintain a gate turn off thyristor (86) conducting to keep the primary 42 short circuited. When the current in coil 50 reverses, thyristor (86) is cut off and a pulse occurs across windings 42, 44 to fire a sparking plug. In a modification, Fig.4 (not shown) the E-shaped core is mounted on the same side of the flywheel as core 50. In a further modification, Fig.6 (not shown) the magnets (150,160) are both mounted in the flywheel. Two triggering coils 50, (104) may be used with different inductance/resistance ratio to give an advance spark with increased rotor speed. The gate turn off thyristor may be turned off quickly by a negatively charged capacitor discharging through a thyristor (see Division H3).

Apparatus for applying a veneer to the inner surface of a hot-top comprises a mandrel 22 with a cavity 23 for receiving fictile veneer material and ports 24 for placing the cavity in communication with the interior of the hot-top, and a ram 37 reciprocable in the cavity to force veneer material therefrom. The apparatus is suspended from a crane 18 and lowered until the mandrel is inserted into the hot - top and located therein by legs 28. Further lowering allows the ram 37 and the weight 38 fixed to it to descend under the force of gravity to expel veneer material from the mandrel through ports 24 into the clearance space between the mandrel and the hottop. Retraction of the ram uncovers ports 36 in its cylinder 33 to allow veneer material M to enter the mandrel cavity from the hopper 31. Further upward movement then moves the ram and mandrel together, a floating ring 26 being picked up by stops 29 on the legs 28 to cover the ports 24 when the mandrel leaves the hot-top. To prevent the suction effect of the ram retraction pulling veneer from the hot-top walls the ports 24 may be closed or partly closed during such retraction. In a modified form of mandrel, the lower part thereof incorporates a piston-cylinder arrangement which vents the mandrel cavity to atmosphere as the ram is retracted.
