Title: Improvements relating to eddy current damping devices
Inventor: MORTON DONALD FRANK
IPC: H02K49/04
Filed: 1969-06-30
Abstract: 1,256,133. Eddy current brakes. BRITISH AIRCRAFT CORP. Ltd. 26 June, 1970 [30 June, 1969], No. 32942/69. Heading H2A. An eddy current damping device e.g. for a gyroscope, comprises a permanent magnet rotor 10 with toothed polepieces 11 surrounded by a cylindrical, non-magnetic, conductive stator 14 having teeth formed by soft-iron bars 13 embedded therein. Relative angular movement between the stator and rotor produces eddy currents in the stator which give rise to an opposing torque and to increase the eddy currents, half the teeth on each polepiece 11 are phase-shifted by half a tooth pitch as shown in Fig. 3a so that when the teeth in Band I of a pole-piece are in register with the stator teeth 13, those in Band II are out of register therewith. Consequently for a given rate of displacement of the rotor, the major phase axis oscillates about the polar axis of the magnet as the bands of rotor teeth come into register with the teeth 13 so that the rate at which the lines of flux cut the damping member is higher than said given rate. The stator teeth may be formed as the polepieces of the permanent magnet or, alternatively, the stator and permanent magnet in Fig. 1 may be stationary and only the rotor teeth movable in the air gap.

Title: Improvements in or relating to cathode ray tubes
Inventor: HILL RAYMOND THOMAS JOSEPH
IPC: H01J29/70
Filed: 1957-10-29
Abstract: 817,496. Cathode-ray tubes. GENERAL ELECTRIC CO. Ltd. Oct. 25, 1957 [Oct. 29, 1956], No. 32966/56. Class 39(1). In a cathode-ray tube, particularly of the kind suitable for use in high-speed oscillographs, the deflecting arrangement comprises a first electrode in the form of a hollow conducting cylinder 6, Fig. 1, flattened along one side and a second electrode in the form of a strip of conducting material 8 wound helically on an insulating former 7, The former is provided with locating members, preferably iri the form of radially projecting rides 10 at each end, which support the former within the cylinder. The shape of the former is such that the helical electrode has a flattened region extending along one side which is arranged parallel to and spaced a predetermined distance from the flattened region of the cylinder. The deflecting arrangement is supported in the tube with the flattened regions of the two electrodes lying on opposite sides of the electron beam path, indicated by arrrow 4. To obtain maximum sensitivity the dimensions of the deflecting electrodes are such that the beam deflecting signals are propagated along the transmission line formed by the two electrodes at the same velocity as that of the electron beam. As shown in Fig. 3, the hollow former 7, which may be constructed of steatite is provided with a longitudinal gap 9 across which the helix 8 is flat. The absence of an insulating surface immediately beneath the helical strip in the vicinity of the electron beam prevents distortion due to wall charges which would otherwise be built up between the turns of the helix. An insulating layer, in the form of a shellac coating on one or both of the electrodes or a sheet of mica, may be interposed between the curved surfaces of the electrodes. A second deflecting arrangement consisting of two metal plates 5 may be arranged to provide a time base for the tube. The tube is especially suitable for examining high frequency voltage signals appearing in coaxial lines, the line being broken at a suitable junction and the inner conductor connected to the helical coil through lead wires 22 and the outer conductor to cylinder 6 through annular contacts 27, connections 26 and tubular stubs 24 spot welded to cylinders 6 over mica washers 23. The first deflecting arrangement may be supported between two metal plates 11 through which pass insulating rods which also carry the plates 5 and an annular metal plate 19. The whole arrangement may be supported at the target end of the tube by spring fingers 20 and at the opposite end by similar fingers attached to one of the electrodes of the electron gun.

Title: Improvements in Data Storage Apparatus.
Inventor: WEBLEY REGINALD SIDNEY
IPC: G11C11/14
Filed: 1965-08-03
Abstract: 1,157,614. Magnetic storage apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. 3 Aug., 1966 [3 Aug., 1965], No. 33044/65. Heading H1T. [Also in Division H3] Magnetic storage elements comprise anisotropic thin film rings (2), Fig. 1 (not shown), positioned at intervals along a coaxial line or its equivalent and located between the inner and outer conductors (1), (4), the easy axis of magnetization extending axially of the line. An embodiment is described in which pairs of such coaxial lines 5, 6, Fig. 3, arranged with their magnetic films 7 in close proximity, form the address conductors of a two-core-per-bit storage matrix. A binary word is written by pulsing each of the coaxial lines of a pair in turn, and applying during the first of the pulses a longer duration pulse to each of digit conductors 8, the direction of current in respective digit conductors being determined by the word to be written. Non-destructive read-out is obtained by pulsing one of the coaxial lines of a pair so that pulses are induced in the digit conductors by flux rotation, the switched films being restored to their initial state by the fields of the unswitched films in the adjacent coax al lines. For destructive read-out both coaxial lines of a pair are pulsed simultaneously. The equivalent of a coaxial line is shown in Fig. 4 in which a storage matrix consists of grooved copper blocks 9, 10 which house the address conductors 11, 12, the digit conductors 13 being located between the blocks in form of printed conductors on a glass or other substrate. As in the previous embodiment the conductors 11, 12 correspond to the inner coaxial conductors carrying current in one direction, and the blocks correspond to the outer coaxial conductors carrying the return current. The use of coaxial arrangements reduces magnetic coupling between the word and digit circuits.

Title: Method of, and improved means for, manufacturing electrically welded tubes
IPC: B23K11/06
Filed: 1959-09-30
Abstract: 913,354. Making tubes; welding by pressure. SONNICHSEN, A. Sept. 30, 1959, No. 33139/59. Classes 83 (2) and 83 (4). In making a resistance-welded metal tube a strip is brought to tubular form, the seam is welded by current passing transversely of the abutting edges thereof, the welding bulge is removed and a further current to anneal the tube is passed longitudinally along the welded seam between roller electrodes spaced along the path of the tube, each electrode engaging the seam. Steel strip 1 is fed between rotary knives 2 to cut the edges off the strip and then to a rolling mill 3 in which it is shaped to an open tube. The tube is then welded between pressure rollers 10 above which an insulated pair of electrodes 12, 13 is pressed against the tube so that current flows from one electrode to the other across the pressed together seam. Weld flash is removed by a knife 5 and the welded tube passes to a set of four electrodes 6, each contacting the welded seam which pass current longitudinally of the tube while rollers 16, 17 exert side pressure. The tube finally passes through a calibrating machine 7. The mill 3, electrodes 6 and device 7 can be used alone to manufacture tubes of poorer quality.

Title: Improvements in or relating to screw and nut devices
IPC: F16B33/00
Filed: 1956-11-01
Abstract: 846,121. Screw and nut gearing. STRANDGREN, C. B. Nov. 1, 1956, No. 33371/56. Class 80 (3). [Also in Group XXIII] In a screw and nut device wherein threaded rollers 8, Fig. 1, are interposed between the screw 6 and nut 1, the thread on each roller is formed as shown in exaggeration in Fig. 5 so that when the full load is applied to the screw and nut the resulting deformation thereof brings all the thread turns of each roller into contact, thereby distributing said load substantially uniformly along the roller. Alternatively or additionally each roller may be divided into end-to-end short sections which are keyed together with a small axial spacing, Figs. 14-17 (not shown). As shown, the screw and nut have multiple threads of opposite hand but equal helix angles. The rollers 8 have single threads and are formed at each end with trunnions 12 rotatable in a ring 13 and with teeth 10 (or an attached pinion) gearing with a toothed ring 3 on the nut. The rings 13 are held, with axial play, by plates 4 secured to the nut. The thread shown in Fig. 5, is obtained by increasingly trimming or rectifying both the upper or screw-engaging face and the lower, or nut-engaging face of successive turns of thread with respect to a standard thread during the grinding of the roller so that the bottoms of the turns lie on arcs of parabolµ ZZ. In the example shown the screw and nut are assumed to have equal cross-sectional areas so that their deformations under load are equal and both thread faces of the roller require the same rectification. Accordingly the roller shown in Fig. 5 has a constant pitch. The threads, shown diagrammatically as straight, are preferably arched. In a grinding machine (see Group XXIII) for simultaneously rectifying both faces of the thread a nut carrier 46, Fig. 9, associated with a screw 44 controlling the pitch of the thread being formed on the roller 8, is mounted on a fixed framework 20 through two pairs of resilient blades, and axial pitchcorrecting movements are imparted to the carrier 46 by a cam-actuated lever 60 linked thereto. The linkage comprises a bar 63 whose ends are connected by resilient blades, which act as pivots, to the lever 60 and to a bar 65 carrying spaced parallel resilient blades 67, 66, these blades being respectively connected to the framework 20 and to the carrier 46 to move the latter. The transmission ratio of the linkage is determined by the spacing between the parallel blades 67, 66. It is stated that the resilient blade connections in the linkage may be replaced by ball or other connections.
