Abstract: 1,096,822. Induction motors. ENGLISH ELECTRIC CO. Ltd. Jan. 8, 1965 [Jan. 16, 1964], No. 2087/64. Heading H2A. In an induction motor having a rotor com prising magnetic material, either solid or laminated, within whose circumference are equispaced the conductors of a squirrel cage winding, and a stator wound with both a running winding of small pole number and which when energized alone form an A.C. source co-operates electromagnetically with the cage winding to cause the motor to run at its running speed and a braking winding of large pole number and energizable from a supply, e.g. A.C. or D.C. electromagnetically to produce a braking torque to decelerate the motor from the running speed by co-operation with the cage winding, the rotor magnetic material has formed within the cage winding equispaced high reluctance axially extending apertures 14 of number equal or substantially so to that of the braking winding poles whereby the braking torque is increased firstly by current unbalance caused in the cage winding and secondly by the differential reluctances around the magnetic material. The braking torque may be further increased by providing a squirrelcage winding in the apertures 14, and the deceleration may be to a low speed or to standstill given a suitable choice of load, rotor resistance, magnetizing reactance, and air-gap. The pole numbers may be 4 and 18 respectively, and simultaneous energization of both windings may provide an inching speed. The apertures 14 and cage slots 15 are unskewed, and in a modification, Fig. 2, the braking and static holding torques are increased by making open at the circumference those slots (16) which are radially aligned with the apertures (14). In a further modification the stator comprises two parts carrying the respective windings.

Patent GB-922169-A (GB)
Title: Liquid to liquid heat exchange
IPC: C02F1/10
Filed: 1962-01-23
Abstract: In a process for effecting heat exchange between immiscible liquids of different densities, a first liquid is introduced into a vertically moving column of the second liquid in the form of discrete droplets which come together to form a closely packed column moving counter to the flow of the second liquid.  As shown in Fig. 1 the process is used to heat sea water passing downwardly through a column A by oil droplets moving upwardly through the column, the hot sea water passing to an evaporating-condensing unit E to obtain hot fresh water which is used to pre-heat the oil in a second, similar heat exchange column B.  Further heat is supplied to the oil by a heater H before it is passed to column A. In the latter, as shown in Fig. 2, sea water from a header 28a passes through tubes 27 and into the heat exchange portion Le of the column which it leaves through tubes 38 located in a perforated plate 37.  Oil is supplied to the space beneath this plate and passes through the apertures 39 therein, forming oil droplets which rise through the water column in a closely packed mass.  A honeycomb structure 30 located around the tubes 27 coalesces the oil droplets and the oil passes through a pipe 64 to a separator 66.  The hot sea water leaves the column through a pipe 12, a separator 46 and a control tank 48 the height of which may be adjusted to vary the ratio of oil to water in the column A. In order to keep the temperature differential between the oil and water as small as possible throughout the length of the columns, the columns A and B may each be divided into two series connected stages and a portion of the partially heated oil from the lower stage of column B diverted to join the partially cooled oil passing from the lower to the upper stage of column A (Figs 10 and 11, not shown). <PICT:0922169/III/1> <PICT:0922169/III/2>
