Title: Improvements in or relating to telephone sets
IPC: H04M1/04
Filed: 1932-03-19
Abstract: 397,230. Supporting telephone sets. BARRINGTONS (DESIGNERS), Ltd., BENNET, J. H., and AGAR, J. H., 89, Ebury Street, Victoria, London. March 19, 1932, Nos. 8177 and 30800. [Class 40 (iv).] Relates to a holder or support for a telephone hand-set of the kind which can be adjusted to any position convenient to the user and which obviates replacing the hand-set on the usual switch rest on completion of a conversation. According to the invention, the hand-set is carried by an articulated or flexible arm mounted to extend laterally from a vertical tube or spindle and manually or automatically operated means are provided for co-operation with the switch rest. Fig. 1 shows one form of construction in which the desk set is secured by clips 2 to a base 1 on which is mounted a pedestal 3 in which a vertically adjustable tube or spindle 4 is secured by a screw 5. The tube 4 carries a laterally extending arm comprising two sections 7, 8 hinged together at 9, the section 8 carrying a spring clip 10 in which the hand-set is adapted to be held. The section 8 may comprise a length of flexible tubing as shown or may be fitted at its free end with a frictional ball or other universal or swivelling joint or with a short length of flexible tubing. The switch rest is normally held depressed by a pad 15 on a pivoted lever 13 which is connected by a link 12 to a further pivoted lever 11, the free end of which is held down against a spring 21 by a spring-pressed catch member 17 engaging ratchet teeth 18 on the spindle 19 of the finger-piece 16. Figs. 2 and 4 show a modification in which movement of the arm 7, 8 from Fig. 4 position into its position of use causes a cam 25 carried bv sleeve 22 to co-operate with the short arm of a lever 27 pivoted to a fitting 28 on the pedestal 3 so as to allow the pad 30 carried by a resilient extension 29 of lever 27 to rise. Accidental movement of the arm into its position of use is prevented by the engagement of projections 32 on a spring-controlled pivoted catch lever 31 with oppositely disposed series of ratchet teeth on a ring-like member 26 above the cam 25. According to a further modification, Fig. 6, in which the arm is constituted by a length of flexible tubing 8, the switch rest is held depressed by a weight 34 on an arm 35 pivoted at 36 to a fitting 37 adjustably mounted on the pedestal 3. The weight may be lifted by hand and held raised by a spring clip &c. catch or, as shown, it may be raised by a cam lever 39 pivoted at 40 to the arm 35 and co-operating with a projecting part 37a of the fitting 37. The projection 37a also serves as a stop limiting the downward movement of the weight. According to the first Provisional Specification a manually operated switch may be provided in the base member for connecting and disconnecting the hand-set.

Title: Improved residual fuel
Inventor: MORWAY ARNOLD JESSE
IPC: C10L1/188
Filed: 1955-03-22
Abstract: A vanadium-containing residual fuel oil has dissolved therein a complex calcium borium or magnesium soap of an acid having 1 to 5 carbon atoms in the molecule and an acid having 16 to 22 carbon atoms in the molecule.  The lower molecular weight acid may be acetic, formic, proprionic, crotonic or acrylic acid, and the higher molecular weight acid may be stearic acid, oleic acid or hydrogenated fish oil acids.  The complex is added to the residual oil in amounts to give 0.02 to 0.5 weight per cent of calcium, borium or magnesium metal based on the residual oil, or in an amount sufficient to secure an atomic ratio of calcium, borium or magnesium to vanadium in the oil of 1/1 to 5/1 .  The complex soap may comprise 10 to 80 per cent by weight of the lower molecular weight acid, and 90 to 20 per cent by weight of the higher molecular weight acid.  The complex soaps preferably formed in the presence of a mineral oil, which may be some of the residual oil, to form a composition which is then added to the residual oil to obtain the fuel composition.  In an example a complex soap is formed from acetic and stearic or hydrogenated fish oil acids, with calcium hydroxide, in mineral oil, and added to a residual fuel oil.

Title: Improvements in method and apparatus for evacuating an electric discharge device of the vacuum type useful as a circuit interrupter
IPC: H01J7/18
Filed: 1966-02-25
Abstract: 1,128,628. Gettering; vacuum switches. GENERAL ELECTRIC CO. 25 Feb., 1966 [11 March, 1965], No. 8354/66. Headings H1D and H1N. A vacuum device-e.g. a vacuum swith-is evacuated by the use of a getter which is reversibly reactive with residual hydrogen left in the tube subsequent to its being sealed, which getter material is retained in one portion of a gas-tight capsule, in which it has been sealed while at a high temperature, by a gas-permeable partition, the wall of the other portion of the capsule being broken subsequent to the sealing-off of the device, whereafter the hydrogen remaining therein is sorbed by the getter. The hydride of titanium, zirconium, cerium, thorium, or vanadium 42, Fig. 2, is sealed within the portion of a stainless steel capsule 40 defined by the porous, sintered, stainless steel member 48 by heating in a furnace through which hydrogen is flowing, passage of gas through the capsule being permitted by radial corrugations in the discs 53 of brazing material placed between the end caps 44, 45 and the cylinder 43. The hydride is reduced to the metal, and the capsule baked out, the brazing discs 53 melting in the range 778‹ C. to 1000‹ C. to seal the capsule. In the manufacture of a vacuum switch, Fig. 1, having two opposed electrodes 25, 26, of which one is movable by means of a bellows 32 to make or break contact with the other, the sealed gettering capsule 40 is placed therein and the glass envelope 16, end caps 20, 21 and corrugated brazing washers 23 are raised to a temperature in the range 450‹ C. to 500‹ C. in a hydrogen furnace, to bake out the tube and seal on the end caps. After cooling, the wall of the empty portion of the gettering capsule 40 is broken by a punch 46, by withdrawal of the movable electrode for a distance exceeding its normal switch-opening stroke, whereafter the hydrogen in the tube is sorbed by the getter metal. In a modified method, the end caps are sealed on first, but either one or two tubes are mounted through one of them to permit, during baking out prior to their sealing off, either the evacuation of the envelope by a pump, or its flushing out with hydrogen.

Title: Separation of iron from ores and minerals
IPC: C22B1/08
Filed: 1960-03-09
Abstract: Ores, materials and minerals, containing iron oxide in the ferric state are treated in a non-reducing atmosphere with a chlorinating gas to separate out vaporous ferric chloride, preferably at above 900 DEG  C., and the chlorinating gas is then regenerated, preferably above 300 DEG  C., e.g. 700-750 DEG  C., in a separate reactor by conversion of the ferric chloride and oxygen to ferric oxide, which is separated, and chlorine, which is returned to the first reactor. If the iron is originally present in a state of oxidation, lower than ferric, the material is pretreated with air at elevated temperature, e.g. above 500 DEG  C., especially 1000 DEG  C., to oxidize the iron to the ferric state. In examples, low grade iron ores were treated for the recovery of ferric oxide, and ilmenite was treated to obtain ferric oxide free from titanium oxide and titanium oxide free from ferric oxide.

A tied sleeper unit for the construction of model railway track is integrally moulded of a flexible, non- brittle plastics material, e.g. polythene, with sleeper portions 1a-1d, having railretaining members 3 moulded on them, tied together by spacer ties 2a-2d located in two parallel rows so as to be beneath rails 4 to be carried by the unit, some sleeper portions being tied to a sleeper portion next adjacent thereto by only a single spacer tie, e.g. 2b, disposed in one of the rows and some of the sleeper portions being tied to a sleeper portion next adjacent thereto by only a single spacer tie, e.g. 2d, disposed in the other of the rows. Thereby, the unit with rails assembled thereon can be flexed to form a curved track. The flexing of the unit may be limited by stops 12. Sleeper units are assembled by engaging a hooked end 8, Fig. 2, of a projecting tie 6 of one unit in an aperture 9 of an adjacent unit and then holding it therein by a rail 4 bearing on a small rib 11. Some of the rail-retaining members 3 may be omitted and be replaced by holes through which spikes may be inserted to fix the unit to a base board. The Provisional Specifications additionally disclose a similar tied sleeper unit which instead of being moulded is stamped from a sheet of fibre board and has pairs of struck up projections to grip rail flanges. They also disclose a moulded tied sleeper unit, e.g. of polythene, having sleeper ties which may be of small cross-section or be of zig-zag construction so that they can stretch to allow flexing of the unit. Alternatively, some or all the ties may have grooves or notches which can snap to permit the flexing.

Abstract: 1372303 Steering vehicles J EHRLICH 26 Feb 1973 [25 Feb 1972] 8831/72 Heading B7H [Also in Division F2]  In a vehicle in which a drive input is coupled to left and right outputs by respective belt and pulley drives at least one of which is of variable ratio, the driven pulley of each drive is coupled to a left or right output wheel and is mounted on an arm which is radial to that wheel, and a steering control is effective to change the relationship between the two drive ratios. As shown, an engine 22 drives a shaft 18 through an automatic belt transmission 23, 24, 25, and pulleys 16 on the shaft 18 are connected by belts 17 with pulleys 15 each of which consists of two axially movable portions pressed together by springs, and the transmission ratios of the two drives 15, 16; 17 are differentially adjusted by movement of the pulleys 15 towards and away from the pulleys 16 by mechanism connected to a steering wheel 33 and comprising racks 28 on either side of a pinion (not shown) and linked by rods 31 to arms 19 which carry the pulleys 15. The arms 19 pivot about the axes of the output wheels which are driven by chains 14. The output wheels may be land Wheels, or paddle wheels for a boat, or wheels driving endless tracks 13. Reverse drive is obtained by tilting the steering column 26 in the fore-and-aft plane to bring the pulleys 15 into contact with the pulleys 16, and steering is then effected by varying the pressure between the pulleys, assisted if necessary by differential application of brakes.
