Title: Improvements in and relating to means for controlling dielectric stresses in electrical insulation
Inventor: HICKLING GEORGE HERMAN
IPC: H02K3/40
Filed: 1964-12-16
Abstract: 1,129,887. Insulation for, and securing coils for, dynamo-electric machines. C. A. PAR- .SONS & CO. Ltd. 16 Dec., 1965 [16 Dec., 1964], No. 51134/64. Heading H2A. Means for controlling dielectric stresses in the insulation of a conductor where it emerges from an electrically-conducting enclosure comprises one or more separate capacitive and resistive members of electrically insulating material at least partially surrounding the conductor and its insulation and in electric contact with the enclosure, the material having a low specific impedance (as defined in the Specification) and the member(s) having an impedance normal to the conductor axis less than that parallel to the conductor axis. Preferred materials are synthetic-resin-impregnated asbestos cloth, asbestos felt, and asbestos paper laminates. Preferably the impedance of the member increases in a predetermined manner with distance from the enclosure. This may be achieved by making the member wedge-shaped (or annular-conical) with the greater cross-section next to the enclosure. 'The member is oriented with the laminations perpendicular to the conductor axis. Alternatively, a material may be used consisting of laminµ of asbestos fabric in which asbestos fibres rare interwoven with glass fibres; or linen, and in this case the member is cut from a block so that the laminµ are parallel to the conductor axis, but in each lamina the asbestos fibres lie perpendicular to the conductor axis while the remaining fibres lie parallel to the axis. In Figs. 5 and 6 the member 4 is arcuate and has slots 10 coinciding with the ends of slots in a turbo-generator stator (not shown) through which conductors emerge; it is held in contact with the stator end face by I section members provided on the latter, and engaged by keyways 12, Fig. 6, in the member 4. Each wedgeshaped portion of member 4, Fig. 6 (crosssection), co-operates with, and lies between, two conductors; the portion tapers in the direction away from the stator core and is separated from the conductors by insulation 5.

Title: Winding machine with automatic tube change
IPC: D03C5/00
Filed: 1974-11-27
Abstract: 1487608 Continuous winding machines MASCHINENFABRIK RIETER AG 27 Nov 1974 [13 Dec 1973] 51320/74 Heading D1J A continuous winding machine of the kind comprising at least two chucks 7, 7' for accommodating the tubes 8. 8' to be wound, the chucks being mounted on a pivotal arm 6 such that as one tube 8' becomes fully wound it can be swung away from a driving friction roller 9 and the empty tube 8 to be wound can be swung into engagement with the friction roller 9, is characterised in that the empty tube 8 is first applied to the periphery of an accelerating ring 18 that is adjacent one end of driving roller 9 and is driven independently of the roller 9 at a peripheral speed exceeding that of the roller 9.  In Fig. 2 the axis of the accelerating ring 12 is eccentric with respect to the axis of the friction roller 9, the eccentricity being such that the accelerating ring 12 projects radially beyond the friction roller 9 in a zone that precedes the zone at which the empty tube 8 will eventually be in contact with the friction roller 9 for winding purposes. In Fig. 2 means (not shown) are provided to axially displace the mandrel of the tube 8 away from the arm 6 to bring the end of the tube 8 into the plane of the accelerating ring 12. When the empty tube 8 has been brought up to speed, and then moved into the winding zone, the mandrel of the tube 8 is retracted axially to its original setting. Alternatively the tube 8 may be of a length sufficient to enable it to establish contact with the accelerating ring 12 without being axially displaced. The arm 6 is mounted on a carriage 4 slidable on rails 2, 3 so that during yarn transfer from the full package to the empty bobbin both can, temporarily be simultaneously in contact with the friction drive roller 9.

Title: Gas turbine engine fuel supply control
IPC: F02C7/26
Filed: 1974-11-28
Abstract: 1487249 Automatic control of fuel to a gas turbine NISSAN MOTOR CO Ltd 28 Nov 1974 [28 Nov 1973 (3)] 51630/74 Heading G3N and G3R A gas turbine fuel control system includes an electromagnetically operated fuel control valve responsive to control signal which varies continuously in magnitude from a first value to a second value after engine starting is initiated. In the system shown a closed'loop control is employed when the engine is running using an operator control 48 which sets a desired speed signal for comparison in differential amplifier 44 with the output of speed sensor 40 to produce a difference signal for operating control valve 18. When the engine is started the shut-off valve 30 is opened and this causes switch 24 to be changed over so that signal generator 32 provides an input signal to function generator 26. The signal from generator 22 has effectively set the output of function generator 26 which includes an integrating circuit to produce a control signal corresponding to the minimum fuel requirement of the engine, i.e. under hot start conditions. The signal generator 32 provides a higher signal which corresponds to the idling speed fuel requirement and the output of function generator 26 will gradually rise to this level to provide a rising control signal to valve 18 giving a steadily increasing fuel supply to the engine. When idling speed is reached function generator 26 will provide a steady output and control is taken over by generator 48.  In a modification, Fig. 1 (not shown), the form of final operator control is not shown and the signal generator 32 produces a signal which corresponds to the cold start fuel requirement.  The system described may be modified by using a detector to sense when the engine starts and using the signal from this detector to operate the switch 24, Fig. 8 (not shown).

Filed: 1970-11-02
Abstract: 1327399 Reticulating foamed material H HARTMEYER 2 Nov 1970 [8 Nov 1969 10 Oct 1970] 52004/70 Heading C3R Foamed material, particularly polyurethane foamed material, having partly or wholly closed cells is reticulated by discharging a high voltage high energy electrical discharge between a pair of electrodes arranged close to the material to be treated thus producing a high speed high energy shock wave passing through the material to be treated. The foamed material may be located close to and between a reflector wall capable of reflecting high speed high energy shock waves and a pair of electrodes or close to and between two pairs of electrodes. Reticulation may also take place under water. In a typical Example, a piece of polyurethane foam is placed in a stainless steel tube having a polished surface, a wire is pressed through a hole bored in the material, the ends of the wire being fixed to two electrodes, and a discharge is produced between the pair of electrodes to produce a completely open celled foam material.
