Title: Improvements in or relating to circuit arrangements for gas- or vapour-filled high voltage electric rectifiers
IPC: H01J17/04
Filed: 1938-08-10
Abstract: 506,475. De-coupling of high voltage rectifiers. PATENTERWERTUNGSGES. HERMES. Aug. 10, 1938, No. 23639. Convention date, Aug. 10, 1937. [Class 38 (ii)] In gas - or vapour - filled high voltage rectifiers having one or more intermediate electrodes between the anode and cathode, for which the potentials for the intermediate electrodes are derived from a potential divider connected between the anode and cathode circuits, the potential divider is decoupled from the anode circuit by an impedance. This impedance, which is not ironcored, may be an autotransformer so that impulses 180‹ out of phase may be fed to the intermediate electrodes to neutralize the effect of the anode-intermediate electrode capacities. The same method may be used to neutralize the capacities between the intermediate electrodes. In the Figure, an autotransformer 12 supplies impulses, 180‹ out of phase with the variations at the anode, to the potential dividing condensers 19 ... 25. Further autotransformers 16, 17, 18 neutralize the capacities between the intermediate electrodes 4 ... 7.

Title: Process of producing pure hydrogen fluoride
IPC: C07C17/38
Filed: 1932-08-31
Abstract: Gases or vapours containing hydrogen fluoride are treated with cold concentrated sulphuric acid which may contain free sulphur trioxide and the solution thus obtained is heated to expel the pure hydrogen fluoride.  The hydrogen fluoride may be thus freed from impurities such as silicon fluoride, sulphur dioxide, hydrogen chloride, organic fluorine compounds, and water.  When the gases or vapours contain water vapour, the concentrated sulphuric acid preferably should contain an equivalent quantity of sulphur trioxide.  The hydrogen fluoride may be stored in the form of its solution in concentrated sulphuric acid the heating step being delayed until the gas is required.  The temperature during absorption should be kept to below 30 DEG  C. by cooling and the subsequent heating may be to 60-100 DEG C.  The gases obtained by the action of sulphuric acid on fluorspar may be thus treated, or those obtained in the fluorination of organic substances and containing organic fluorine compounds and hydrogen chloride.  In the latter case, if the resulting solution in sulphuric acid is too weak for direct regeneration it may first be charged completely with crude hydrogen fluoride.  Examples are given.

Title: Improvements in devices for detecting faulty feed of sheets to machines
IPC: B65H7/02
Filed: 1951-10-25
Abstract: 717,047. Feeding sheets. FABER & SCHLEICHER AKT.-GES. Oct. 25, 1951 [Oct. 26, 1950], No. 24948/51. Class 100 (1). [Also in Group XL (b)] Faulty feed control devices.-A device detecting absence or faulty positioning of a sheet in, for example, a printing-machine fed with sheets underlapping each other in a continuous succession comprises two or more detector members one positioned below the sheet and the other moved in timed relation to the feed of sheets from a position below the plane of the sheet to a position above it and in line with the other detector member. Fig. 1 shows an arrangement in which the underneath detector member is in the form of an electrical contact 7 located in a bore in the feed table. The other detector member 6 is carried on a lever 5 mounted on a rocker 3 rotatable on a shaft 1. The detector member 6 is moved towards member 7 for the detecting operation by a push rod 9 displaced against the action of a spring 10 by a lever 8. In the rest position (shown dotted) the rocker 3 is below the plane of the sheet and swings upwardly to the detecting position in timed relation to the sheet feed so that if a sheet is fed too far forward, and lies over the front stops when these move into position. it is lifted by the rocker and the aligned detector members will respond to the absence of a sheet therebetween to trip the printing-machine. After tripping, a plate 12 moves under the push rod 9 to maintain the contacts 6, 7 closed. To detect a smaller movement of the forward edge of the sheet beyond its correct position, detectors as used in Fig. 2 may be used. In this arrangement a second pair of contacts 13, 14 are provided. If the sheet passes between these contacts the printing-machine is tripped. The contacts 13, 14 may be replaced as shown in Fig. 4 by a rocking lever 17 having a sensing pin 16 at one end and at the other a contact 18 co-operating with a fixed contact 19. In the detecting operation the pin 16 enters an opening 15 in the feed tab'e when the sheet is correctly positioned. If the sheet has moved too far and covers the hole the contacts are moved together and cause tripping of the printing machine. In the form of Fig. 6 one of the detector members is a lamp 20 and the other a light-sensitive cell 21, the beam of light shining through a hole in the feed table but being interrupted by the sheet when correctly positioned. In a modification both the lamp and cell are mounted below the feed table and a mirror is moved into such a position above the table that the light can pass from the lamp to the mirror and be reflected to the cell, suitable holes being provided in the table. A. correctly fed sheet will interrupt the light and prevent energization of the cell.
