Title: Improvements relating to inductive apparatus
Inventor: JONES JOHN ERNEST
IPC: H01F29/14
Filed: 1964-11-26
Abstract: 1,066,370. Transformer. FERRANTI Ltd. Feb. 7, 1966 [Nov. 26, 1964], No. 48057/64. Heading H1T. [Also in Division H3] The coupling between the two windings of an inductive apparatus (e.g. transformer) is controlled by a third winding which saturates the ferromagnetic screen on which it is toroidally wound and which screen separates the two main windings. A cylindrical laminated limb 10 (Fig. 2) carries the first winding 12 and has its part circular end flanges 11 shaped to accommodate a control winding 14 which is wound toroidally on a laminated ferromagnetic cylindrical screen 13 in the two opposite spaces not in magnetic contact with the core 10. The second winding 15 is wound around the screen 13 over the winding 14. The control winding 14 is energized with direct current to produce a magnetic field in the screen 13 perpendicular to the fields produced by either main winding 12, 15 whereby the screen may be saturated to regulate the coupling between the windings. The iron core 10 may be replaced by a three-link core in magnetic contact with the screen 13 to provide a return flux path, with the outer links passing outside winding 15. An alternative arrangement includes a second screen (16) (Fig. 3, not shown), placed around the outer winding 15 and provided with a second control winding (17) to vary the saturation of the second screen (16). The two screens may be connected such that the saturation of one screen increases while the other decreases. When the primary and secondary windings are divided into seriesconnected sections and interleaved, a separate screen may be located between each section of the primary and the adjacent sections of the  secondary. The arrangement may form an electric switch if the primary winding has a high impedance and is connected into the circuit to be controlled, while the screened secondary winding is made to have a low impedance (e.g. by short-circuiting the winding). When the control winding is energized, the low impedance of the secondary is reflected into the primary to greatly reduce the primary impedance (e.g. stated impedance ratios of 100 to 1).

A method of flock coating objects provided with an adhesive coating is characterised in that the flock fibres are introduced under pressure into a closed container 13 in which the fibres are dispersed in the form of a cloud by means of an agitator e.g. an oscillatable membrane 24 or perforated flexible tube 30 supplied with compressed air and thus performing twitching or whipping movements, fibres centering a chamber 12a communicating with the container 13 being blown by compressed air through a member 28 maintained at high potential and through a deflector 29 on to the adhesive coated surface of the object, which is maintained at earth potential. The adhesive coating is preferably a two component adhesive comprising a plastics component and an accelerator, the two components being introduced into a mixing chamber 3 via pipe lines 1, 2, a rotary screw 5 being arranged in the chamber 3 to mix the components and expel the adhesive through a nozzle orifice 8 and deflector 9. The adhesive mixer and flock fibre disperser may be combined in a unitary assembly or be separated and may be readily manipulated by hand or mechanical means. In the particular embodiment described, the deflector 29 is coupled to a nozzle 10 via a pipe line 11. The member 28 is preferably in the form of an elastic ring electrically connected to a supporting member 15 supplied with direct current. The supporting member 15 is provided with ducts 19, 20 which communicate with ducts 17, 18 in a fitting 16. The ducts 17, 19 supply compressed air to the chamber 12a; the ducts 18, 20 may house a shaft of a motor for rotating an eccentric member 21 for oscillating the membrane 24, or may supply compressed air to the perforated tube 30. In a further preferred embodiment, a ring (33) maintained at high tension potential is positioned intermediate the deflector (29) and object (32) to be coated, Figure 5 (not shown).

[Also in Division H1] An apparatus for securing a tubular member within a tubular envelope of a vacuum electric device comprises a plurality of rotatable spindles extending parallel to one another and arranged so that they can be inserted into the annular gap between the tubular member and the surrounding envelope, each spindle having a slot adapted to engage a tab on one of the members, and means for rotating the spindles so that the tabs are turned to positions in which they clamp together overlapping flange-like parts on the two members. A vacuum electric switch has an outer wall comprising two glass tubes 3 and 5 connected by an annular metal member which is itself made up of two parts, an L-shaped member 11 and a channel-shaped member 9. A tubular metal shield 15 is formed of two parts 15B and 15C which each have an outwardly extending flange 15A. The flanges 15A are welded together and rest on the part 13 of the member 7. The radially innermost side of the channel 9 has a number of L-shaped slots at spaced points around its periphery, each slot defining a tab 19, which can be bent to a position over the flange 15A to lock it against the part 13. The apparatus for bending the tags comprises a disc 21 secured to a spindle 23 and having a number of spindles 25 journalled in bushes spaced around the periphery of the disc. At the upper end of each spindle is a short lever 31 which is connected by a link 33 to a point on the periphery of a smaller disc 35 secured to a hollow spindle 37 which is concentric with the spindle 23. Rotation of the spindle 23 positions each of the spindles above a tab 19 and rotation of the spindle 37 then causes rotation of the spindle 25 to bend the tab. The lower end of the spindle has a projection 27A which engages under a lug 15D on the part 15B so that the spindles can also be used as a device to transport the sleeve to the envelope. In a modification the lugs are formed on the envelope. The linkage system for operating the spindles may be replaced by a pinion at the top of each spindle which meshes with a gear-wheel on the hollow spindle 37.
