Title: A continuous flow method and apparatus for determining adsorption isotherms of solidmaterials
IPC: G01N15/08
Filed: 1962-08-30
Abstract: 961,642. Determining surface characteristics. ENGELHARD INDUSTRIES Inc. Aug. 30, 1962 [Sept. 5,1961], No. 33414/62. Heading G1S. Surface characteristics of a porous solid are determined by passing a continuous flow of a constant mixture of gases, only one of which is adsorbable by the solid, over the solid and analyzing the effluent, e.g. by means of a thermal conductivity cell, to determine the amount of gas adsorbed. The pressure of the gas mixture is gradually increased e.g. to 200 atmospheres and an isotherm of relative pressure against adsorption plotted. From these results the external surface, pore volume and pore structure of the solid can be calculated. A reference stream of the gas mixture may be provided in addition to the test stream which passes over the solid.

Title: High tension heavy duty circuit breakers
IPC: H01H33/16
Filed: 1966-07-27
Abstract: 1,103,708. High voltage, heavy current switches. MASCHINENFABRIK OERLIKON. 27 July, 1966 [17 Aug., 1965], No. 33775/66. Heading H1N. A circuit-breaker has a pair of hollow terminals 1, 2 and a metal rod 5 bridging them and movable in an insulating tube 3, to interrupt a high voltage direct current for instance, the contact spaces being filled with a highly conductive electrolyte which is rapidly diluted during the interruption. The interior of terminal 1 communicates through a valve 8 with an electrolyte reservoir 7 and through a valve 10 with a pure water reservoir 9. Under overload, sensed by a current transformer 15, a control apparatus 16 first opens valve 8. Compressed air or nitrogen (free of CO 2 ) from a source 12 drives the electrolyte from reservoir 7 into terminal 1 thus driving the contact rod 5 towards the open position. The resistance of the electrolyte is thus inserted between the contacts 5, K. Shortly after, the valve 10 is opened and valve 8 is progressively closed so that the flow of liquid through tube 8 changes from pure electrolyte to pure water increasing the resistance. When the reservoir 9 is exhausted, the compressed air or nitrogen flows through the tube 3 to extinguish the residual current arc or alternatively series connected low current breakers 4 are opened. The hot liquid flows from tube 3 into a reservoir 18 through a non-return valve 19. The contacts may be reclosed after reservoir 18 is drained and reservoir 9 recharged with pure water by injecting compressed air and electrolyte through a valve 14. The valves 8, 10 may be replaced by non-return valves and the flow of the liquids controlled by means of valves in the compressed gas system. The fixed contact member K and the rod 5 are slotted so that the electrolyte begins to flow before the contacts separate. The purity of the water in reservoir 9 can be maintained by an ionexchange unit 20. The electrolyte may be an aqueous solution of an alkali metal compound and the tube 3 may be of P.T.F.E. which is not wetted by the electrolyte.

Patent GB-466429-A (GB)
Title: Process for purification of earthy minerals and improving their colour
IPC: C09C3/00
Filed: 1935-12-06
Abstract: Earthy minerals such as clay are bleached by treatment in aqueous suspension first with a hydrosulphurous acid compound such as zinc hydrosulphite, and then with an alkaline reagent such as caustic alkali, alkali carbonate, trialkali phosphate, or borax in sufficient amount to cause thickening of the clay slip. Thickening when zinc hydrosulphite is used occurs with the precipitation of zinc oxide. When caustic soda is used for the treatment barium zinc, or calcium chloride may also be present.  A clay treated with potassium carbonate may be treated with magnesium sulphate to remove excess alkalinity and precipitate magnesium carbonate.  Successive alternate treatments with hydrosulphite and excess alkali up to the thickening point of the clay slip may be given.  Examples of procedure are furnished. According to the Provisional Specification, the hydrosulphite may be replaced by any other bleaching reagent, and the alkaline reagents may include alkaline-earth metal hydrates or carbonates.

Title: An improved process for the production of an artificial silk thread or yarn in a continuously operating process
IPC: D02J13/00
Filed: 1933-12-04
Abstract: Artificial silk threads are dried in a continuously operating process by allowing the threads to run on to the drying roller with no tension or only a small tension, and withdrawing and winding them with no tension or only a small tension.  The tension should not exceed 5 g., and is preferably less than 1 g. per 100 deniers of thread.
