Title: Improvements in and relating to methods of and apparatus for measuring magnetic induction
IPC: G01R33/028
Filed: 1921-01-21
Abstract: 178,226. British Thomson - Houston Co., Ltd., (General Electric Co.). Jan. 21, 1921. Magnetic t e s t s and measurements. - In a method of measuring magnetic induction by connecting a coil linking the magnetic flux with an indicating-instrument, such as a ballistic galvanometer, adapted to measure the quantity of electricity flowing through the coil due to changes in the flux, an opposing flow of current, sufficient to maintain the instrument undeflected when the magnetizing force and consequently the flux is varied, is produced by a manually-operated device arranged so that the amount of its movement measures the change in the flux. In the form shown, a ring 1 of the magnetic material under test is magnetized by a measured, reversible, variable current in the primary coil 2. The secondary coil 8, shunted by a variable resistance 9, is connected through a highly-damped ballistic galvanometer 10 and a variable resistance 19 to a rotatable Faraday disc 11 with bushes 17, 18 which collect current induced by rotation of the disc 11 in the field of magnets 13, 14. When the magnetizing face in the coil 2 is varied, the deflexion of the galvanometer 10 is reduced to zero by continuous rotation of the disc 11. The extent of the rotation of the disc 11 corresponding to each change in the flux, as well as the total rotation corresponding to the total change in the flux from the beginning of the test, is measured by means of a fixed pointer 16 co-operating with a scale on the disc 11.

Title: Improvements in web stretching and guiding device
IPC: B65H23/02
Filed: 1918-02-19
Abstract: 151,292. Bolton, J. T., and Forsyth Dyeing Co. Feb. 19, 1918. Feerling webs.-In a web stretching and guiding device of the kind described in Specification 114,334, [Class 51 (ii), Furnaces and kilns for applying &c.], the rotating member carrying the feeler finger is mounted on an axis at an acute angle to the axis of the stretching roller. The feeler finger is also provided with means for removing a fold from the edge of the web. As shown the stretching roller 26 and the member 28 carrying the feeler finger 34 are freely mounted on a shaft 24 which is bent slightly so that the axes of the roller 26 and member 28 are at an acute angle to each other. The roller 26 has a part of its priphery rough and a part smooth. The roughening of the roller may be effected in any suitable way such as by providing the roller with small pins or by partially covering it with sand-paper, but is preferably effected by covering one half of the surface with a sheet 45, Fig. 7, of sheet metal having a number of punched holes with their rough edges on the outside. The sheet 45 is secured by bars 32, 48 arranged in recesses 43, 44. The shaft 24 is secured to a bracket 21 adjustable on a bent guide bar 18 angularly adjustable in a bracket 14 so as to vary the inclination of the roller to the web. The member 28 is rotated in unison with the roller 26 by means of a pin 31, which may be an extension of the bar 32, engaging a slotted arm 29 of the member 28, and when the web is running correctly, the finger 34 passes freely between the limbs 42, 39 of a yoke securely to the bracket 21. If the web deviates excessively it obstructs the passage of the finger 34 and arrests the roller 26 with its smooth surface in engagement with the web which thereupon slides laterally into correct position. The finger 34 is provided with a bent-over end 36, Fig. 4, so that if the edge of the web 11 becomes folded during excessive deviation, the fold 37 engages the end 36 during the return of the web to normal position and is thereby removed.

Title: Improvements in landing arrangements for aircraft on moving craft
IPC: B64F1/36
Filed: 1928-01-30
Abstract: 284,591. Theis, K. Jan. 29, 1927, [Convention date]. Landing places and launching ways. - In a landing device for aircraft, for use on ships, other aircraft &c., the landing device is movable and is released, and its speed controlled, by the aircraft before it lands. In the arrangement shown in Fig. 2, a movable device 13, adapted to run along members 12 mounted on one or each side of the ship 11, carries an arm 15 having a depending resilient member 16 at its outer end, a receiving cable 17 being connected between the members 16 and 13. A member 18 on the arriving air-craft is adapted to engage the cable 17 when the aircraft lands. The movable device 13 is driven along the ship 11 so that its actual speed approximates to the speed of the arriving aircraft, and for this purpose two or more controlling devices each carrying a series of contact members 23-25, similar to those shown on the left-hand side of the ship, are arranged in the path of the aircraft before it reaches the landing device 13. Contact of the aircraft with the first series of contact devices releases and starts the movement of the device 13 which may be driven by an electric motor, the speed of the drum 13 being determined by the time elapsing before the aircraft arrives at the second series of contact members and being further controlled if desired by other series of contacts arranged in the flying path. After the aircraft has become attached to the cable 17, the device 13 may be retarded, and if the driving motor is electric it may be used for this purpose. The contact between the cable 17 and the member 18 on the aircraft may be utilized to short-circuit the ignition devices of the aircraft engine. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement in which the arm 15 is pivoted on the member 13 and is held in the normal transverse position by springs. Further, as shown in Fig. 1 (Cancelled), the alighting aircraft 10 carries a member 9 adapted to engage with a member 8 connected by resilient devices 6, 7 to a trolly 5 movable along tracks 2 on an airship 1. This subjectmatter does not appear in the Specification as accepted.
