Title: Improvements in and relating to windings for transformers, reactors and other inductive apparatus
IPC: H01F27/28
Filed: 1929-04-10
Abstract: 309,596. British Thomson-Houston Co., Ltd., (Assignees of Compagnie Francaise pour l'Exploitation des ProcÚdÚs Thomson- Houston). April 13, 1928, [Convention date]. Drawings to Specification. Coils; windings.-In inductive windings in which the turns consist of several conductors in parallel, unequal current distribution due to the individual conductors being subjected to different flux densities is avoided by proportioning the number of turns for each conductor in accordance with the flux density to which it is subjected, the conductors so positioned in the winding as to be subjected to the higher flux densities having a smaller number of turns. The Specification compares this method with the method according to which the conductors have equal numbers of turns but are transposed at intervals along the length of the winding. The invention is stated to be applicable to slot-wound machines.

Patent GB-289831-A (GB)
Title: Improvements in sighting telescopes destined for use on an oscillating platform
IPC: G02B27/64
Filed: 1928-04-17
Abstract: 289,831. Naamlooze Vennootschap Nederlandsche Instrumenten - Cie. May 3, 1927, [Convention date]. Telescopes.-Sighting telescopes for use on an oscillating platform are mounted in a carrier and are rotatable about a horizontal axis, which is itself rotatable about a vertical axis. The sighting line is displaceable in elevation by tilting an entrance reflector about an axis perpendicular to the axis previously mentioned. A gyroscopic device, provided with sighting marks, is mounted in the casing carrying the telescope, and arrangements are provided whereby the telescope is rotated about its horizontal axis to bring certain sighting marks into coincidence, such movement rendering the tilting axis of the entrance reflector horizontal. A base plate 1, secured to the oscillating platform, supports a carrying body 2, rotatable about the axis X-X by the hand-wheel 3. Pivots 6 in the body 2 carry a ring 7, rotatable about the axis Y-Y, which itself supports on pivots 8 a casing 9, moving about an axis X-Z. This casing 9 supports the telescope, consisting of an eyepiece 17, prism 19, objective 21 and prism 22, the latter being tilted by gearing from the handwheel 24. The ring 7 is displaced by rotation of the handwheel 13 and gearing shown in Fig. 2. A gyroscope 32, having a vertical axis of rotation, is supported in a ring 31, so that its cardan axes coincide with those of the casing 9, the axis of rotation of the ring 31 being parallel to that of the tilting axis of the prism 22. A glass bowl 33 carrying a mark 34 in the axis of the gyroscope is carried by the gyroscope casing, and moves in proximity to a similar bowl 35 carried by the casing 9. A mark 36 on the bowl 35 lies in the optical axis of the telescope and the marks 34, 36 are viewed by the eyepiece 38. The focal length of the objective is equal to one-half of the distance between the posterior principal point H of the objective 21 and the centre M of the two cardan suspensions, the focal plane passing through the point N which is the intersection of two sighting wires 40, 41. In use, the gyroscope 32 rotating, the observer at the eyepiece 17 adjusts the casing 9 in azimuth bv the wheel 3, and the sight in altitude by the wheel 24 until the target is observed at the insertion N of the cross-wires. A second observer at the eyepiece 38 maintains the marks 34, 36 in coincidence by tilting the casing 9 by the wheel 13 about one axis, and by the wheel 10 about an axis at right angles. The result is to maintain the tilting axis of the prism 22 horizontal and the optical axis of the telescope, between the prisms 19 and 22, vertical. In a modification, the casing 9 is only rotatable about the axis Z-Z and the mark 36 is made a line, and is used for telescopes having a comparatively low magnification.
