Title: A method of determining geographical longitude and apparatus therefor
Filed: 1933-12-05
Abstract: 423,461. Determining longitude. KENSIK, A., Swiecie, Poland. Dec. 5, 1933, No. 34135. [Class 97 (ii)] The change in the direction of the meridian as indicated by a magnetic compass during a great circle course is used for determining the number of degrees of longitude travelled over. The latitude of the starting point must be known and this may be deduced from the known direction and velocity of travel and the rate of change of the angle between the meridian direction and a great circle course. In the case of travel on land, a vehicle adapted to move in a series of straight paths and therefore in a series of part great. circles is made in two sections, viz. a front section comprising a pair of road wheels and steering means and rear section comprising rear road wheels and the superstructure. Turning of the steering wheel directly imparts an identical turning to the front section followed by an equal swing of the rear section. The steering wheel 1 turns in an aperture 3 in and has an arm 2 extending over a board 4 fixed to the rear section and having two concentric grooves 5, 6, each containing a rotatable graduated ring. Each ring is rotatable in one direction only and oppositely to the other. Facing halves of the grooves 5, 6, are covered by the board 4 so that fingers 7, 8 on the arm 2 upon turning of the steering wheel cause the rings in the grooves 5, 6 to rotate to sum the turnings of the vehicle to the right and left respectively. The difference between the readings of the two rings gives the angle between the direction of the vehicle at the starting point and that at the finishing point and forms a basis for measuring the change in direction of a magnetic needle 9 mounted on the steering wheel. A marker on the steering wheel may record the turnings of the vehicle on a roll of paper automatically wound from one reel to another at a rate proportional to the velocity of travel and provides data from which a plan of the course may be drawn. Fig. 6 shows a device for use in sea or air navigation. A compass casing 12 is suspended by a ball and socket joint 15 from the centre of a rapidly revolving disc 12 hung on a universal joint 14. The compass casing may also be connected by universal joint on the underside to a second disc revolving in the opposite direction. It is stated that the compass casing maintains a fixed position due to its own inertia so that the variations in direction of the needle may be determined directly.

Title: Improved means for securing the edges of fabrics woven in shuttleless looms
IPC: D03D47/40
Filed: 1929-11-11
Abstract: 343,436. Treating fabrics in looms. BRITISH CELANESE, Ltd., 22, Hanover Square, London, DICKIE, W. A. and HALE, F. C., of British Celanese, Spondon, near Derby. Nov. 11, 1929, No. 34372. [Classes 142 (ii) and 142 (iv).] One or both edges of a fabric being woven in a shuttleless loom are treated with a solvent, softening agent, or swelling agent, which softens the warp and/or weft threads at the edge treated and d renders them sticky or tacky so that they adhere to contacting threads in the fabric edge. When the fabric contains thermoplastic material such as threads of cellulose acetate &c., the threads may be softened by heat. Adherence of the threads may be assisted by pressure. The heat may be applied continuously by passing the fabric edge between rotating rollers one or both of which may be heated, or intermittently in a manner described. Alternatively, a solvent, softening- agent, or swelling agent may be applied by a pad 10 communicating with a container 9 by means of a wick 11 passing through a tube, a hammer 12 on a cam-controlled bell crank lever moving the fabric into contact with the pad at intervals. The edge of the fabric may pass between rollers, one of which has a fluted surface to which solvent is applied. The fabric may comprise weft threads of cellulose acetate &c. and warp threads of cotton, silk, wool or of viscose, nitrocellulose or cupra ammonium silk, or both warp and weft may comprise threads of a cellulose derivative, or the edge warp threads may consist of a cellulose derivative. Acetone, triacetine, ethyl lactate, diacetone, alcohol, chloroform, cyclohexanone, Schweitzer's reagent and zinc chloride solution may be used as solvents &c.

Abstract: 941,533. Gyroscopic apparatus. ANSCHUTZ & CO. G. m. b. H. Sept. 26,1961 [Sept. 30,1960], No. 34514/61. Heading G1C. In gyroscopic apparatus, such as a gyrocompass for geodetic purposes, in which the rotor 19, Fig. 1, is electrically driven, a battery 21 is carried by the rotor carrier 17. As shown the battery 21 may feed a transistorised generator 20 supplying multiphase alternating current to the field windings of the rotor motor. The carrier 17 is supported from a fixed frame member 10 by a fluid bearing comprising a ball 12 and a supply of compressed air or oil. To cage the gyro, a nut 27, Fig. 2, is rotated to raise plunger 25 into engagement with a projection 23 on the bottom of carrier 17 and thus raise the latter into engagement with a fixed ring 22. The battery 21 is then charged from an external source through contact 29. The rotor may initially be run up to speed whilst caged and the external current source thus supplies the starting current. In a modification the carrier 17 floats in liquid and is suspended by a torsion band. In a further form the carrier 17 is spherical and has a multiplicity of rotors whose 'axes are separately adjustable.

Title: Improvements in or relating to refractory siliceous material
IPC: C04B35/14
Filed: 1947-12-30
Abstract: A refractory material is prepared by grinding a mass containing a high percentage of silica with 25-35 per cent of water without any other binding agents until a sticky paste is formed which, on heating to a temperature of 1000-1500 DEG  C. is converted into a mass capable of withstanding a temperature of 1800 DEG  C.  The material is ground in a mill with quartzite balls, the resulting plastic mass is allowed to stand for a period of at least one month, and is then pressed to shape or rammed into place.  Up to 50 per cent of less finely-ground silica may be included to reduce shrinkage.  A coating of graphite to render the material resistant to slag erosion may be applied.  The Specification as open to inspection under Sect. 91 comprises also the use of ground used silica bricks to counteract shrinkage, the application of the process to magnesia and chromite, and the use of a neutral or acid binding-agent.  This subject-matter does not appear in the Specification as accepted.
