Title: Improvements relating to telephone systems

Abstract: 345,741. Automatic and manual exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and PETERS, C. L., 21, Croft Villas, Green Lane, Eltham, both in London. Jan. 25, 1930, No. 2674. [Class 40 (iv).] Voice-frequency currents of different frequencies are used for control and supervision respectively over a two-way junction. Reference is made to the control of automatic switches, but the invention is described with reference to wholly manual working over a two-way junction, signals sent from the calling end being regarded as control signals and those in the opposite direction as supervisory signals. Normal operation. On the insertion of a plug into the calling jack OGJ, K switches over from the answering jack and Y operates C which connects up the control generator GC and energizes X which uncouples the junction from the jack. B after a brief interval couples the generator GC and the receiver RS. At the distant office RCXB lights the calling and busy lamps and energizes XB to cut off the operator's circuit from the junction. When she answers COB energizes SB which connects up the supervisory generator GSB. RSX at the originating end energizes A which locks V and releases C to cut off the control generator GC. At the answering end RCXB falls and ACSB pulls up and connects RB to the upper talking wire to signal the operator who then throws her listening key energizing YB and releasing SB, XB to cut off the supervisory tone and complete a talking circuit. At the other end RSX falls and ACS pulls up and connects R to the upper talking wire to give the answering signal. X falls back and completes the talking circuit. When the answering operator restores her listening key YB is released, when the called subscriber replies it reoperates and when he clears it again falls, these actions being signalled to the distant operator by SB, RSX, ACS as described above. When the originating operator clears, K, Y fall and shortly afterwards B, a momentary circuit being made for C which thus applies control current to the junction for a short period. RCXB at the distant office pulls up temporarily, releasing ACSB which disconnects RB to give the clearing signal, and energizing DB which locks and prevents re-operation of ACSB. When the answering operator clears COB falls followed by SB, DB, and B. Second operator takes the junction before answering operator clears. Relays K, Y, B, C, M, pull up, the last only temporarily. RSX responds to the supervisory currents, which are on the line because the distant end is not cleared, but before A can pull up it is disconnected by N which locks up. When the answering operator clears, COB allows the calling lamp to light and releases SB to cut off the supervisory currents. RSX thus falls, unlocking N and the call can now proceed normally.

Abstract: 735,031. Pneumatic springs. MINISTER OF SUPPLY. Jan. 27, 1950 [Jan. 31, 1949], No. 2678/49. Class 108 (3). In a shock-absorbing device for a freight container dropped from an aircraft a fabric bag is attached to the underside of the container and is inflated by the dynamic pressure due to the passage of the equipment through the air. As shown, Figs. 1, 2, 3, the inflatable bags 11, 12, 13 are secured to the container 10 and while inside the aircraft the flaps 27, 28 are held shut by locks 31, 32 and the bags deflated, Fig. 1. After the container leaves the craft the flaps are unlocked by a timed release, not shown, and opened by the elastic cords 33, Figs. 2, 3. The bags are inflated by the passage of air through non-return valves, not shown, in the lower surface of the bags. When the ground is reached, the non-return valve closes and the air in the bags is compressed and when a predetermined pressure is obtained, thin membranes covering the side holes 19 are burst and the air escapes gradually through 19. In a modification, the membranes may be provided with small holes.

[Class 39(iii)] [Also in Group XXIII] For maintaining a hollow annular glass body, such as a betatron envelope, within the annealing range during manufacture (see Group XXIII), two electrically heated ovens are used having rotatable mounting spiders therein pivoted respectively vertically and horizontally. The oven walls are of flat asbestos cement sheets mounted on a steel framework and with a soft asbestos sheet lining spaced therefrom; removable panels or doors allow access to a sector of the glass for working, close fitting asbestos shields being used to isolate this sector. The first oven is heated by six starconnected zig-zag sheathed elements mounted as a ring round the peripheral oven wall, one element being withdrawn when the panels are removed for working; the second oven is heated by twelve starconnected rod fire-bar elements mounted in rows, six on each side. A three-phase supply may be fed alternately to the heaters (both ovens are not used simultaneously) through an intermittent energy regulator; the oven temperatures are measured by thermocouples.

[Class 39 (i)] The grid of a gas-filled electron discharge device, such as a thyratron having a long and slender cathode, is solid and has one or more apertures arranged transversely to the cathode, so that small errors in the positioning of the electrodes will not affect the performance of the device. In Figs. 4 and 5, the grid 18 has three apertures, and when the device has fired, the resultant conduction from the cathode 20 to the anode 22 is through one aperture only. In Figs. 6 and 7, the grid 26 is U-shaped and arranged around the cathode 28 which has only a small emissive coating 30 arranged opposite a single aperture in the grid. An auxiliary negative grid comprising the two arms 38 of a U-shaped rod is arranged between the grid 26 and the rod-shaped anode 42. The grid 26 may, alternatively, be arranged to electrostatically screen the anode instead of the cathode, and the grid aperture may be perpendicular to the cathodes as shown, or at some other substantial angle thereto. The cathode, anode, and grid 38 extend through upper and lower mica locating members 50, 52, through which also project rods 32, 36 to which the solid grid 26 is secured, the rods 32, 36 being lap welded to dummy and lead-in conductor rods 56, 37 which, together with rods 40, 44 to which the grid 38 and anode are respectively lap-welded, support the lower member 52. The cathode is connected by a tab 48 to a similar lead 46. The upper member 50 is held by staking the rods above it and by welding getter-strip 54 to rods 32 and in contact with the member.

Title: Process for catalytically dehydrogenating hydrocarbons
IPC: C07C5/333
Filed: 1946-01-29
Abstract: Hydrocarbons are dehydrogenated in the presence of a catalyst consisting essentially of alumina and at least one other metal oxide having dehydrogenating properties, the catalyst having been prepared by fusing hydrated aluminium sulphate and a compound of the other metal, calcining, and reducing to remove sulphur.  The dehydrogenating metal oxides are derived from compounds of molybdenum, chromium, tungsten, uranium, vanadium, columbium and tantalum, for example ammonium molybdate, tungstate, and vanadate, vanadyl sulphate, tungstic acid, chromic acid, and chromium oxides and sulphate.  Zinc and magnesium oxides derived from the sulphates may also be present as stabilizers.  In preparing the catalyst, the aluminium sulphate is used in the fused state or as a concentrated solution, calcining is carried out at 200-600 DEG  C., and reduction with hydrogen or illuminating gas at 350-650 DEG  C.  A subsequent treatment with an oxygen-containing gas, such as air, may be given. The catalyst is formed into granules, extruded or pelleted using hydrogenated coconut oil as a lubricant, or reduced to a powder for use in a fluidized process in which carbonaceous deposits are removed from the catalyst by oxidation.  The dehydrogenation processes include the conversion of naphthenes to aromatics, paraffins to olefines, olefines to diolefines, the cyclization of aliphatic hydrocarbons, and the reforming of gasolines or naphthas with or without hydrogen to increase their anti-knock value (see Group IV (b)).ALSO:Hydrocarbons are dehydrogenated in the presence of a catalyst consisting essentially of alumina and at least one other metal oxide having dehydrogenating properties, the catalyst having been prepared by fusing hydrated aluminium sulphate and a compound of the other metal, calcining and reducing to remove sulphur.
