A heat-exchanger plate comprises a central quadrilateral area of continuous corrugations (3) projecting on both sides of the median plane of the plate, and extending parallel to two flat, marginal edge portions of the plate, the plate having triangular end zones beyond the corrugations and each bounded by one of the marginal edge portions. The triangular end zones may be flat, dimpled, corrugated transversely of the plate or provided with short fluid directing corrugations. Triangular corrugated sheets may be secured to the end zones of the plates when these are flat (Figs. 1, 4, 5 and 7, not shown). In a stack of the plates, the respective fluids may enter and leave the plate interspaces by openings formed either at the ends or at the sides of the assembly, the plate interspaces being sealed at their edges by straight or L-shaped spacing strips (10, 11) and the assembly being welded or brazed between backing plates (7). Alternatively the edges of adjacent plates may interlock (Fig. 9, not shown). Mutual support for the plates at the end zones is provided by the corrugations or dimples in these zones and these may project from one side of the plate to a distance twice the height of the main corrugations (3) (Fig. 3, not shown). Alternatively in these zones, dimples equal in height to the main corrugations (3) may project from both faces of the plate. In an annular plate assembly described, the alternate passage spacing strips (10) are tapered (Fig. 2), whilst the intermediate spacing strips (11) are of uniform thickness.

Abstract: 657,234. Cathode-ray tubes. ELECTRO ACOUSTIC INDUSTRIES, Ltd., and BARDEN, G. A. Feb. 24, 1949, No. 5073. [Class 39 (i)] In a device for adjusting the magnetic gap between soft iron polepieces on a cylindrical magnet surrounding the neck of a cathode-ray tube, three screws cooperate with a flange on a tubular polepiece and a fixed plate on the magnet assembly. In the embodiment shown, the magnet 1 has polepieces in the form of plates 2, 3 having apertures 4, 5, respectively, the latter one being larger to accommodate the tubular polepiece 6 between which and the polepiece 2 is the adjustable magnet gap 11.

Alternatively screws may engage freely plate 3 or the flange 7 and engage threaded holes in the flange or the plate, tension or compression springs being located between the plate and flange. Further, screws having heads captive on the flange may engage threaded holes in plate 3. The above construction may be used with a device for separately varying the gap as a whole comprising a tubular member having slots or grooves co-operating with a pin or pins or vice versa, the adjustment being obtained by rotating the member.

Abstract: 580,054. Root crop harvesters. JENSEN, F. A. March 22, 1944, No. 5309. [Class 6 (iii)] [Also in Group XXX] A machine for lifting and loading root crops growing in or deposited on the ground comprises a rotary lifter having a plurality of sets of tines 38, an endless band conveyer having a plurality of sets of tines 20 adapted to pass between the tines 38, and means for driving the lifter and conveyer in opposite directions in such manner that the tines 20 overtake the tines 38 and remove from them the roots they have lifted from the ground. The conveyer shown comprises a frame 11 supported on a wheeled frame 10 by means including an adjustable strut 12, the frame being fitted with sprockets over which pass chains 17. The chains are connected at intervals by bars 18 between some of which are angle bars 19 carrying the tines 20. The side members of frame 10 are connected at their rear ends by a transverse member 22, and carry axles 23 for the land wheels 24. The rotary lifter comprises a spindle 28 carried by a U-shaped frame 27 pivoted on the axles 23, a screw and nut mechanism 34, 36 being provided on member 22 for adjusting the position of the lifter. The tines 38 pass through a cylindrical body 37 and are secured to spindle 28. This spindle is driven by gearing from the axles 23, and a sprocket or pulley 40 on the driving shaft of the conveyer is driven by a chain or belt from a sprocket or pulley on one of the wheels 24. For feeding root crops from a dump the rotary lifter is removed and then replaced in a reversed position in the same bearings, and the distance between it and the conveyer is increased by altering the inclination of the latter. The rotary lifter is then driven in a clockwise direction and serves, to transfer the roots from a grid-like frame, Fig. 3 (not shown), to the conveyer.

Abstract: 175,995. Frei, H. Feb. 23, 1921, [Convention date]. Armatures and field-magnets; alternating current induction machines.-The inducing-member of an alternating-current machine, shown applied to a two-phase induction motor in Figs. 1 and 2, comprises a ring coil 6 for each phase arranged concentrically with the machine shaft within packets of sheets, of the type shown in Fig. 6, having ends 14, 15 to form a row of imbricated poles opposite to the active iron of the induced member. The limbs 11, 12 of the packets are bent in opposite directions, as shown in Fig. 2 to permit insertion of the coils and they are held in spaced relationship by non-magnetic insertions 28. The packets have recesses 17 engaging ribs 19 in the flanges 18, 23, 24, 26 which, by means of tightening rings 21, 27 secure them on the stationary hub 20. The short-circuited rotor 2 is carried by a bell-shaped member 4 so as to surround the stator but, alternatively, the inducing member may rotate with the shaft, in which case current is led to the ring coils by means of slip-rings. A three-phase motor is also described with a stationary inducing member comprising three ring coils coaxially mounted in packets of iron of the form shown in Figs. 7 and 8. The central coil is contained in stampings as shown in Fig. 7 and has on the right-hand of it a coil in stampings as shown in Fig. 8. The left-hand coil is also contained in stampings as in Fig. 8, but reversed end for end, the three sets of polar faces a, b being imbricated at the central zone opposite to the rotor bars. The rectangular polar extremities shown in Figs. 7 and 8 may be undercut as in Fig. 6. The Specification, as open to inspection under Sect. 91 (3) (a), states that a three-phase motor of this type may be arranged with switch gear to give a delta connection of its coils for threephase running and parallel connection with the current reversed in one coil for single-phase' running at a reduced speed and output. Also that a two-speed single-phase motor may be obtained by reversing the current in one of the coils, the central coil being used as an auxiliary starting-coil. This subject-matter does not appear in the Specification as accepted.
