Abstract: 396,174. Control of D.C. motors. RAMSDEN, H. K., 26, Ashlands, Ashton-on- Mersev, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. April 22, 1932, No. 11607. Drawings to Specification. [Class 38 (iii).] In a traction system in which the shunt fields of compound-wound motors are weakened for high speed and strengthened for low speed, both for motoring and regenerative braking in series and in parallel, the change from maximum to minimum shunt field excitation, when the motor connections are about to be changed from parallel to series during regenerative braking, is effected in at least two steps, the motors remaining in parallel after the first reduction in field strength has taken place. Simultaneously with the first reduction in field strength a resistance may be introduced in series with the motor armatures. More than two stages of reduction may be used and when the motors are finally connected in series with their shunt fields fully reduced during regenerative braking, the shunt fields are again increased. The sequence of changes during motoring is the reverse of that during braking. Numerical examples of the shunt field currents are given in the Specification.

Abstract: 181,898. Chapman, E. B. April 22, 1921. Magnetic separators.-In a magnetic separator for removing solids from liquids such as ferrous matter from oils in lubricating-systems, a series of magnetic elements, which may be of the type described in Specification 150,101, are used in combination with one or more cages of non- magnetic material having openings disposed so as to cause the liquid to flow uniformly past the more strongly magnetic portions of the elements. In the form shown in Fig. 1, four circular series of horseshoe magnets 4 are arranged within a metal casing 1 having inlet and outlet openings 2, 3 for the liquid to be treated. On the inner, outer, or both sides of the rings of magnets are circular cages 9 having slots 10 disposed so that the liquid is caused to flow laterally past the strongly magnetic portions of the magnetic system. In addition to the cages 9, cylindrical strainers 11 may be employed on either or both the inner and outer sides of the magnetic elements. In order that the magnets may be removed together with the cages 9, the latter may be connected at the bottom by a ring 14 on which the magnets rest. In modifications, electromagnets are used in place of permanent-magnets. In the construction shown in Figs. 8 and 9, two series of magnets 15 extend inwardly from opposite sides of the casing, the flow of liquid across the fields being controlled by slotted cage plates 16 arranged between the poles. In the arrangement shown in Fig. 10, a cage 18 is arranged between an oil inlet 19 and an upstanding trunk 20 opening into the drain-tank 17 of a lubricating- system, electromagnets 15 being disposed between the cage and the trunk.

[Class 114.] Variable pitch propellers wherein the blades are mounted in sockets in a hollow boss have the blade roots extended beyond the propeller axis, each root being supported in two journal bearings one on each side of the axis, and between the ends of the blades is a thrust bearing whereby the centrifugal force on one blade is balanced by that on the other blade. Centrifugal torque is balanced by masses disposed in the roots acting thereon through rollers and inclined surfaces. The boss is' slidable on the shaft and coacts with a cam to vary the pitch in accordance with the ratio of the thrust to torque, this automatic control being subject to an over-riding manual control. A frame 4 is secured to the propeller shaft and within it is mounted the boss 5 with its sockets which are connected by lugs 6 and universally jointed rods 3 to the frame 4. The frame 4 carries rollers 8 engaging cam grooves on arms 7 secured to the root of each blade whereby the pitch is varied as the boss moves axially. Each blade 11 carries a sleeve 9 and a prolongation 13 secured thereto by a nut 16, the complete unit being mounted in an outer bearing 17 and an inner bearing 18. The inner ends of the prolongations 13 have a common thrust race, in which balls or rods 20 with spherical ends are employed, and at their outer ends have balance weights 29. Within the sleeve 9 is an annular mass free to move outwardly under centrifugal force. It is guided by rollers 21, 22 on a rod carried by the sleeve and also has inclined slots 27 which are engaged by rollers 23, 24 on the prolongation 13 of the opposite blade, whereby a corrective control of the centrifugal couple is imposed. For providing a limited over-riding control a lever 33 is linked through a lost-motion device 34 to a lever 32 connected by a sleeve 30 with the slidable boss 5.
