A member 10 is longitudinally slidable in the shaft 4 under the control of worm gearing 42 and link 44, Fig. 3, to actuate the Garret arms 14. In the working position-of the arms, shown left of Fig. 1, the drum is clutched to the shaft, which is driven by a motor 7. The Edenborn carrying arms 26 are operated by spring-loaded racks :27, vertically movable by a cam surface 36 on a toothed ring 37 which may be rotated by a motor 40. An outer drum 19 serves as a protection and has a seat 21 which, when the arms 14 are withdrawn, engages a braking surface 22 in an outer ring 23. A chamber 3 contains cooling water, which may be discharged through a closable pipe 3a on to the wire bundle. When the apparatus is to operate as a Garret block, the guide tube 48 is placed in position, arms 26 are swung aside by the motor 40, the Edenborn guide tube 17 removed and the member 10 brought into its lowest position, thus swinging the arms 14 up beneath the drum, which at the same time is coupled to the shaft 4 and rotated. By actuation of the gear 43 and parts 10, 11 and 13-16 the carrying arm 14 may then be swung out again and a finished coil discharged onto a cooling bed 49. For use as an Edenborn block, the tube 48 is removed and the member 10 drawn upwards so that arms 14 are swung into the interior of the drum. In this position the Edenborn guide tube 17 can be set in the member 10 and secures it in position. The arms 26 are swung up to the end of the block by means of the motor 40 and the drum uncoupled from the shaft 4 so that it remains stationary. The arms 26 may be swung downwardly to discharge a finished coil on to the cooling bed.

Abstract: 868,557. Aerials. VICKERS AIRCRAFT HOLDINGS Ltd. May 12, 1959 [June 5, 1958], No. 18050/58. Class 40(7) A wide-band aerial of relatively small height consists of a modified monopole designed to be resonant, by the use of capacity loading, at a frequency fo and also, due to the incorporation of a short-circuited stub, at two frequencies one above and one below #o. The aerial may consist of top and bottom members 13 and 15, in the shape of two halves of a hollow circular disc joined as indicated. Between the members is a circular disc 14 connected to the top member 13 at 12. The assembly 12, 13, 14, 15 is mounted above an aircraft skin 16 by a short aerial length and fed by a coaxial feeder as shown. The whole unit may be embedded in solid diaelectric and form a button constituting a relatively small protuberance. The equivalent circuit of the aerial is shown in Fig. 4, the branch 1 of which represents the action of the top-loaded unipole part of the unit and the branch 2 the action of the shortcircuited stub indicated at ABCD. It is explained that the effect of the two branches combined gives a series of three resonant frequencies of which the centre-one is that to which the two branches are tuned; i.e. that to which the top loaded unipole is tuned and that at which the stub is a quarter wavelength long. The deviation from zero susceptance between the resonant frequencies is not great (Fig. 5, not shown) and so the aerial is suitable for broad-band work.

Abstract: 139,836. British Thomson - Houston Co., (General Electric Co.) Nov. 8, 1919. Exciting.-In the method of regulating a dynamo-electric machine by means of an auxiliary motor 7 having its armature connected up to produce a counter electromotive force in the field circuit 4, the speed of the motor 7 is controlled throughout its entire speed-range by a brake 11, and its excitation is regulated by a vibratory regulator 17. The solenoid 18 of the regulator 17 and the field winding 12 of the eddycurrent brake 11 are connected across the mains 5, 6. Sudden changes in the speed of the motor 7 are prevented by means of a fly-wheel 16, or by constructing the armatures 7, 15 so that they function as a fly-wheel. The brushes of the armature 8 are so positioned as to produce a magneto-motive force in opposition to that produced by the winding 9; or an opposing field winding may be provided on the motor 7, either connected in series with the armature 8, or connected across a series field winding on the main machine. In the application of the invention to alternating- current machines, the solenoid 96, Fig. 5, of the regulator 94 is connected to the alternating current mains through a transformer 97, and the field windings 87, 88 of the brake 86 are connected across the field windings 78, 79 of the exciters 76, 77 or across the exciter armatures. Additional regulating solenoid windings 95 may be provided in the regulator 94, one connected in series with the vibrating contacts, and the other connected across the field winding 78 or in series therewith. In the arrangement shown in Fig. 5, the vibrating regulator 94 controls the excitation of the motor 80 through a relay 93. In a further modification, the vibrating contacts are adapted to short-circuit a portion of the exciting-winding of the regulating-motor.

Abstract: 890,611. Electric tests. STRACKE, G. June 9, 1958, No. 18337/58. Class 37. An electrode for use in liquids comprises at least two parts in close mutual contact, relative movement between them providing continuous cleaning of the active electrode surfaces. As shown, in an arrangement for measuring the oxygen content of waters and sewage, an electrode comprises a metal disc K which rotates in the test liquid and an element S which is spring-urged against the periphery of the disc K, connection to the measuring circuit being made via either or both of members K and S. Surfaces of members K and S, other than those in mutual contact, are insulated against the liquid. Oscillatory or any other type of motion may replace rotation, and rapid motion of electrode part(s) relative to the liquid renders the measurement largely independent of the flow rate of the liquid. The other electrode A may be fixed, as shown, or constructed according to the invention.
