Title: Rotary inertia mechanism
Inventor: TREVASKIS HENRY WILLIAM
IPC: B64D1/02
Filed: 1950-11-16
Abstract: 728,434. Rotary inertia systems. DUNLOP RUBBER CO., Ltd. Oct. 22, 1951 [Nov. 16, 1950], No. 28016/50. Class 78 (5). [Also in Group XXXIV] A rotary inertia mechanism limiting the acceleration of a glider when towed by an aircraft, comprises a rotatable member 1, a flywheel 13 capable of limited angular movement relative to said member, an electric switch having contacts 25, 27 and a spring 15 urging the fly-wheel. As shown, the glider carries a rotating system which comprises spindle 3, spigot 2 and housing 1 and is driven by gearwheel 35. The said fly-wheel 13 is contained in the housing 1, the fly-wheel being mounted on bearings 14 and being connected to the base 6 of the housing through said spring 15. The electric switch is located in recess 16 of the flywheel ; the contact 27 carried by housing 1 is connected by cable 21 to slip rings 32, and contact 25 carried by the fly-wheel is connected thereto by cable 22, the slip rings being connected by plunger 34 to a current source. The gear-wheel 35 is driven by the winch upon which is wound the cable which tugs the glider. The pay-out of the winch is braked pneumatically. When the braking is too great so that the acceleration of the glider exceeds, a predetermined value relative movement occurs between fly-wheel and housing so that the switch is made, the switch controlling a valve which releases the air from the brakes and so allows the towing cable to pay out more freely. A handle 8 is provided, the position of the handle being determined by plunger 9 engaging with one of a series of holes formed in cover 4, so as to vary the tension of the spring and thus the predetermined maximum acceleration of the glider permitted. Specification 560,201, [Group XXXIV], is referred to.

Title: Improvements in or relating to a Device for a Measuring Device of the Surface Tension of Liquids
IPC: G01N13/02
Filed: 1967-06-21
Abstract: 1,192,936. Testing surface tension. COMPAGNIE DES COMPTEURS. June 21, 1967 [June 21, 1966], No.28689/67. Headings G1A and G1S. A device for measuring the surface tension of liquids comprises a test body 10 made by the assembly of a number of thin plates 10A, 10B, 10C of a glass or metal in the shape of part of an annulus, glued together on one half α/2 and parallely spaced on the other half, the assembly being connected to axis 11 at the centre of said annulus, means 16, 17 being provided for measuring the torque exerted on said axis which results from the surface tension of the liquid when the test body is partically immersed therein. The test body is counterbalanced to be in equilibrium about the rotational axis 11, and due to surface tension of the liquid in which the body is dipped more torque will be applied to the side of the test body in which the plates are separated than to the other side and the test body will rotate about the axis 11. The testbody is brought back to the equilibrium position by means of a moving coil 16 attached to an arm 15 and associated with an electromagnet 17. The variation in position of a puddle 18 actuates an amplifier 19 which sends a current to the coil 16 to restore the equilibrium position, the current being proportional to the torque which is in turn proportional to the surface tension. The device may be permanently fixed in a tank to indicate the surface tension of the liquid in the tank independently of variations in the liquid level or its S.G. and so on.

Title: Improvements in working up gases containing hydrocarbons in electric arcs
IPC: C07C4/10
Filed: 1931-10-16
Abstract: <PICT:0389165/IV/1> In the electric-arc treatment of gaseous or vaporized hydrocarbons, or liquid or solid hydrocarbons in suspension in a gas, the striking points of the arc are caused to move rapidly on the surfaces of both electrodes, whereby the deposition of carbon is checked.  The striking points of the arc may be caused to move by electromagnetic means or by means of a stream of gas, which may be the gas to be treated or another gas such as nitrogen or hydrogen; the rate of movement should be at least 5 cm., and preferably more than 20 cm., per second.  Alternating current or rectified alternating current is preferably used.  The electrodes may be of copper, iron, or graphite.  As materials which may be treated, mention is made of natural gas, propane, coal gas, coke-oven gas, gases from the low-temperature carbonization of coal or lignite, waste gases from the destructive hydrogenation of coal, tar or mineral oil, and liquid hydrocarbons or brown coal dust suspended in hydrogen.  Suitable apparatus comprises an electrode E, an earthed tube F, and gas inlets G1, G2.  A part of the gas is introduced tangentially at G2, the rotary movement of the gas imparting a rapid movement to the striking points of the arc.  An example is given in which a gas containing 95 per cent of propane is treated in the apparatus described, yielding a gas containing 14-16 per cent of acetylene.
