Title: Improvements in electromagnetic couplings for the transmission of mechanical power
IPC: H02K49/02
Filed: 1940-08-27
Abstract: 541,825. Electromagnetic driving-couplings. ENGLISH ELECTRIC CO., Ltd., CALVERLEY, J. E., and CARNEGIE, H. S. Aug. 27, 1940, Nos. 13529/40 and 9795/41. [Class 35] In an electromagnetic coupling in which torque is transmitted by the inter-action of a primary field system on one half of the coupling with a secondary system on the other half in which current can be induced by movement thereof relatively to the field system, means are provided for varying at will the relative rotation of the secondary system and a magnetic field with which it is linked, the variation being independent of the rotation of the primary and secondary systems. As shown in Fig. 1, one half 1a of the coupling transmitting power from a motor 8 to a shaft 9 comprises a magnet core similar to the armature of a D.C. machine with the windings connected to slip rings 1 b and to a commutator 1c. The other half 1d, forming the secondary system, comprises a magnetic core surrounding the armature and carrying a secondary winding connected to slip rings and with its circuit closed through a variable resistance connected across the brushes ; alternatively a squirrelcage secondary winding may be provided, or no winding at all. In normal running D.C. is supplied to the primary winding through brushes 2 and slip rings. By throwing over the switch 4 and supplying the brushes 3 the primary magnetic field will become stationary and effect a retarding action on the secondary winding which action may be varied by rotation of the brushes 3. In another form, the commutator may be omitted and the switch 4 effect a change from D.C. to an independent and constant frequency A.C. supply, the primary being a multi-phase winding ; the D.C. supply may be omitted by making the A.C. supply of variable and controllable frequency. Or the brushes 2 may change from one constant frequency A.C. supply to another. The form shown in Fig. 3 includes a tertiary system 1e which is stationary and has field windings connected to a D.C. supply by the switch 4. In a modification, the field windings on the tertiary system are supplied with D.C. through a commutator and relatively rotatable brushes when the switch is operated. In a further modification the switch disconnects the brushes from D.C. and connects the field windings of the tertiary system to A.C. of two or more phases of variable and controllable frequency ; the switch may be a three position switch to connect the field winding of the tertiary system to either of two such A.C. supplies of different frequencies. With the motor 8 at rest the shaft 9 may be driven by rotating the brushes 3, Fig. 1, while connected to the supply or by rotating the tertiary system in the other forms while excited.

Title: Improvements in or relating to ultra high frequency apparatus
IPC: H01P1/12
Filed: 1945-09-04
Abstract: 597,217. Wave-guides. MULLETT, L. B. July 14, 1944, No. 13545. [Classes 40 (iii) and 40 (v)] In ultra-high-frequency apparatus employing a wave-guide for the transmission of energy, the passage of wave energy in a wave-guide is controlled by means of a probe which is mounted so as to be capable of being advanced into or retracted from the wave-guide by longitudinal movement. Fig. 1 shows a transformer in which E0 waves in a circular guide 1 are converted into H1 waves in either of rectangular guides 2 or 3. Steel probes 4, 5 arranged at a distance of one-quarter wavelength on each side of the axis of guide 1 are arranged to project alternately into guides 2, 3 by means of cams 6, 7 on a shaft 8. This causes the energy from guide 1 to pass alternately into guides 2, 3. A resonant ring 9 of the kind described in Specification 597,216 prevents reflection of H1 waves back into guide 1. The probes may be positioned in the guides 2, 3 at a distance of three-quarters of a wavelength from the axis of guide 1. In this case, small bulges 10 are formed in the opposite walls of the guides to prevent sparking. Specification 608,839 also is referred to.

Abstract: 419,371. Vertical retorts. WRIGHT, H. T., 10, New Bond Street, London. May 11, 1933, No. 13740. [Class 51 (ii).] Charging and discharging.-In a vertical retort for low temperature carbonization in which fuel is fed to a heat-treatment zone, then ejected into a cooling zone, and finally discharged, the successive operations are effected in a continuous cycle, the intervals between the stages of which are automatically controlled by a timing device. As shown, the retort 1 is fitted with rotary fuelsupply and coke-discharge valves 11, 5, and with a grate 2 over which reciprocates a cutter bar 3 serving to eject the coke from the treatment zone into the cooling hopper 4. The cutter bar is carried by screwed rods 9, 9<1> engaging in screw-threaded bores in worm wheels 8, 8<1>, the latter being driven, to reciprocate the rods 9, 9<1>, through gearing from an electric motor 6. Limit switches 10, 10', engaged by the rods 9, 9<1> at the ends of the strokes of the cutter bar serve to reverse the motor, and supplementary limit switches are provided to open the motor circuit should the cutter bar move beyond either of its limit positions. The circuit for the motor 6 includes two electric clocks, the setting of which can be varied to vary the operation of the cutter bar ; for example, the setting may be such as to cause the motor to run in one direction for seven minutes and then stand at rest for thirteen minutes, wherenpon the second clock repeats the operation in the reverse direction. The two clocks may be replaced by a single clock which controls the movement of the cutter bar in both directions. The motor 6 also operates the coke discharge valve 5 through a rod 31 and pawl-and-ratchet mechanism 32, 33, while a separate motor 18, connected in the same circuit, actuates the fuel supply valve 11 through rod 19 and pawl-andratchet gearing 20, 21. The points of connection between the rods 19, 31 and the pawlcarrying arms 20, 32 of the respective valves are adjustable so that the rate of fuel supply and coke discharge can be varied independently of the rate of operation of the cutter bar. The valves 5, 11, each comprises, as shown in Fig. 6, a water-cooled casing 12 enclosing a cylindrical rotor 15 having inlet and delivery openings and divided into two chambers by a central web 17.
