Title: Improvements in Hydrostatic Logs and other Instruments.
Inventor: KARL TORSTEN FREDRIK JUNG
IPC: G01P5/17
Filed: 1918-06-17
Abstract: 117,448. Jung, K. T. F. Oct. 18, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Logs.-To obtain increased sensibility at low pressures in hydrostatic logs in which fluid pressure acts upon a flexible chamber, the pressure is taken up partly by the flexible chamber itself, which takes a part which is a linear function of its displacement; and partly by a second resistance which takes a part which is the sum of a linear function and a more rapidly increasing function of the same displacement. A pilot-tube 2 acts upon the base 1 of a bellows 4. A stem 6 connected to this base passes up through the bellows to a pivoted angle-lever 7 which rests on the stem by means of a knife-edge adjustable by a screw 9. A spring 11 pivotally hung at 12 is pivoted at 10 to the top of the angle-lever. A set-screw 13 serves to tension the spring 11 which is given an initial tension. A cone 18 driven by clockwork 19 engages a friction roller 17 carried by a rod 16 which has a roller 15 bearing on a cam 14 carried by the angle lever. The rod 16 is urged by a spring lever 21 pivoted at 22 to keep the roller 17 in contact with the cone. The cam 14 is of such shape that the angular velocity of the roller 17, in all positions on the cone, is proportional to the speed of the ship. A revolution counter 24 is driven from the roller 17. A link 25 connects the angle-lever with the speed pointer. Modified forms of spring resistance are described and shown, among which, in the form shown in Fig. 5, the spiral spring acts on a cam formed by a steel band 33, the tension and curvature of which are adjustable by screws 35, 34.

Title: Improvements in the manufacture and production of unsaturated gaseous hydrocarbons and mixtures of carbon monoxide and hydrogen
IPC: C07C2/78
Filed: 1927-04-12
Abstract: 269,547. I. G. Farbenindustrie Akt.- Ges. April 15, 1926, [Convention date]. Gaseous mixtures; natural gases, utilizing.- Mixtures of carbon monoxide and hydrogen are obtained from saturated hydrocarbons or gas mixtures containing them by subjecting the saturated hydrocarbons to a. treatment suitable for producing unsaturated hydrocarbons, separating the unsaturated hydrocarbons, and treating the residual gases with steam and/or oxygen (or gases containing oxygen) in presence or absence of a catalyst. The treatment of the residual gases may be assisted by an electric arc. In one example, a mixture of methane (20 per cent) and hydrogen (80 per cent) is passed through an electric arc and yields a gas containing acetylene, which is adsorbed in active charcoal. The residual gas is brought to a temperature of about 1100‹ C. by preheating and partial combustion and is then passed with steam over a catalyst consisting of nickel and alumina. The product is a mixture of hydrogen and oxides of carbon, together with a little methane. In another example, natural gas is subjected to incomplete combustion and the product, which contains acetylene, is passed at 700‹ C. over silica coated with graphite, whereby benzene is formed. The benzene is adsorbed in active charcoal and the residual gases are saturated with water vapour, preheated, subjected to partial combustion, and, after addition of steam, passed over a catalyst consisting of nickel and magnesia. The product is an impure hydrogen-carbon monoxide mixture. Specifications 264,845 and 265,234, [both in Class 2 (i), Acetylene], are referred to.
