Abstract: 1,182,310. Sulphur tetrafluoride. AIR PRODUCTS & CHEMICALS Inc. 20 April, 1967 [20 April, 1966], No. 18263/67. Heading C1A. Sulphur tetrafluoride is prepared by contacting fluorine and molten sulphur in a reactor at 300‹ to 450‹ C. and separating the tetrafluoride from the volatile reaction product. Preferably the fluorine is anhydrous and the reaction zone is made of material resistant to corrosion from fluorine and sulphur at 200-500‹ C., e.g. steel, copper, nickel or platinum. The reaction zone may contain agents of high surface area for distribution of molten sulphur and fluorine moves countercurrent to the flow of sulphur in the reaction zone. Alternatively, the molten sulphur is distributed as a liquid film on a heated rotatable drum and fluorine gas passes countercurrent to the movement of the sulphur-coated drum so that continuous contact between the fluorine and sulphur is obtained. Reaction may be effected at elevated pressure. Comparative experiments describe the reaction carried out at below 300‹ C., the products then being predominantly SF6.

Title: Electrical timing device for photographic exposure
IPC: G03B27/80
Filed: 1958-06-09
Abstract: 878,102. Photo-electric control. AGFA A. G. June 9, 1958 [June 19, 1957], No. 18420/58. Class 40(3) [Also in Group XX] In a photographic exposure timer of the type in which the charge on a capacitor increases at a rate determined by a photo-electric cell until a valve whose grid is connected to the capacitor is triggered determining the exposure, in order to control the exposure in accordance with the law Itp=k the potential of a further electrode of the tube is varied. In the arrangement shown in Fig. 1 when the main switch 56 is closed, tube 21 fires, relay 22 is operated and the contacts go to the positions shown. Exposure commences by operating key 58 which cuts off tube 21 de-energizing relay 22 and lights the printing lamp 1. At the same time capacitor 27 begins charging at a rate determined by the light intensity incident on photo-cell 26. As the capacitor charges the grid potential of tube 21 rises. De-energization of relay 22 also closes a magnetic coupling 40 which allows motor 42 to drive a potentiometer wiper 34 varying the potential applied to the cathode of tube 21. This potential varies according to the law U=U o (t/t o )<SP>1-P</SP> where U is the   cathode potential and U o  is the potential at zero time (t o ). A predetermined relative potential between grid and cathode of tube 21 triggers the tube to energize relay 22 and terminate exposure. The potentiometer 34 may be so formed and series resistors 30, 32 so adjusted as to produce the desired value of p. If potentiometer 34 is linear its wiper may be adjusted through a cam member. In a further embodiment (Fig. 2, not shown) the cathode potential is derived from a capacitor charged through series resistors at the same time as the grid potential is derived from the capacitor charged through the photo-cell. In a modified version of Fig. 2 (Fig. 3, also not shown) cathode potential is controlled by means of a pair of CR circuits so arranged that the potential controlling the charge on a first condenser tapped to supply the cathode is reduced as charge on a second condenser increases.

Abstract: 274,283. Davis, N. R., and Metropolitan-Vickers Electrical Co., Ltd. July 26, 1926. Metals, powdered, obtaining coherent masses from.-A process for sintering refractory metals which are chemically active when hot consists in slowly heating a pressed powder body of the metal in a maintained high vacuum so as to drive off and remove the occluded gases at a temperature below that at which they will chemically combine with the metal, then allowing the body to cool under the maintained high vacuum, and finally heating the body quickly to the sintering temperature either in a vacuum or in gas or in air at a low or at atmospheric pressure. In the case of zirconium, the occluded gases may be removed at 350‹ C. and the metal may then be heated to 800‹ or 1000‹ to effect a preliminary sintering before the intermediate cooling stage, and the final sintering is effected near the melting point by electric induction heating or by passing a current through the body. The initial heating may be effected in a resistance furnace.
