Title: Improvements in or relating to writing devices of the kind of stylographs, pencil-holders and the like
Inventor: ARMAND BOURBON
IPC: B43K24/12
Filed: 1964-01-27
Abstract: 1,020,230. Writing instruments. ETABLISSEMENTS A BOURBON & FILS. Jan. 27, 1964 [Jan. 29, 1963], No. 3387/64. Heading B6P. An appliance containing a number of writing instruments for writing in different colours has devices whereby projection of one instrument causes the retraction of a previously-projected instrument. As shown, four ballpoint pens 18 ... 21 are mounted in a barrel comprising a sleeve 2 and cap 1, and are retracted by springs 28. The upper part of the cap 1 has a circular hole 4 opening on to a flat face 6, and also has four radial slots 7 with outwardly-facing openings 8. The openings 8 extend below the face 6. Each pen has an operating knob 18c ... . 21c, Fig. 15, which is approximately a quarter of a circle in section and, in retracted position is accommodated in one of the slots 7 with a serrated part facing outwardly for manipulation thereof. One radial face of the knob has a notch 25, with a cam part 27, and also a shoulder 26. A member 9 with four radial arms 10, Fig. 12, one corresponding to each pen and each having a cam face 12, Fig. 15, has a pin 11, Fig. 1, which fits into the hole 4. The end 13 of the pin 11 is bevelled and, when the upper faces of the arms 10 abut against the face 6, the bevelled end fits into a bevelled recess 5 at the upper end of the hole 4. A second four-armed member 15 situated beneath the member 6 has a pin 16, Fig. 7, engaging a hole 14, Fig. 5, in the member 9. The member 15 is held against rotation by lugs 17, Fig. 12, on the inside of the barrel and the knobs 18c . . . 21c. With all the pens retracted, the member 9 is positioned angularly by the engagement of the bevelled edges 5, 13 under the action of the springs 28. In this position, the notches 25, Fig. 15, are level with the member 9 and the shoulders 26 abut against the underside of the member 15. When a knob is moved downwardly to project a pen, the cam surfaces 12, 27 cause a rotation of the member 9 which effects a slight downward movement of the member 9 due to the bevel edges 5, 13. The pen is moved downwardly until the end of the knob is beneath the member 9 which thereupon returns to its initial position under the action of springs 28, causing the bevel edges 5, 13 to lock the pen in projected position. Downward movement of another knob effects similar rotation of the member 10 which causes the first projected pen to be released and returned to its retracted position. The flexible nature of the pens allows them to bend and enter the hole 30 in the point end of the sleeve 2.

Filed: 1930-02-06
Abstract: 348,562. Flow meters. HODGSON, J. L. and RATCLIFF, J. R., of Messrs. G. Kent, Biscot Road, Luton. Feb. 6, 1930, No. 3993. [Class 69 (i).] In apparatus for indicating the rate of flow of fluids, in which an obstruction moves in a conical vertical tube, the tube 1 is formed of metal or the material known under the Trade Mark " Bakelite," and is mounted in a casing 2 having an inlet 5 and outlet 7. The obstruction 8 is of conical or other self-centring shape and carries a depending rod 9 and pointer 10 located in a transparent graduated tube 11. The upward movement of the obstruction 8 is limited by stops 13, and an enlargement 6 of the casing effects a slowing of the rate of movement at the upper end. The downward movement is limited by a member 14 connected to the pointer by a spring 15, and constituting a dashpot when the tube is filled with liquid. When the device is employed for measuring very small minimum flows, the member 14 may be a float which takes part of the weight of the obstruction. The apparatus may be placed in shunt across an orifice inserted in a fluid main. Guides 19 may be provided in the casing to prevent swirl of fluid, and a sump 20 may be provided for deposits. The obstruction 8 may be a shell open at the top, or it may be a closed surface pierced with holes at the bottom. A definite flow may be made to pass at a given scale reading, by adjusting the weight of the parts which move with the obstruction. A shaped or parallel float may be attached to the pointer, and move in a heavy liquid, or a light chain may be attached, to give an extended rang of measurement.

Patent GB-717496-A (GB)
Title: Improvements in or relating to stabilised platinum group metals and alloys thereof
IPC: C22C5/00
Filed: 1951-02-21
Abstract: A grain stabilized metal compact consists of a metal of the group platinum, iridium, osmium, palladium, rhodium and ruthenium or an alloy of these metals having silica uniformly distributed through it. The compacts may be used in the production of platinum ware, contact points, furnace heating elements, thermocouple wires and gauze catalysts.  In place of silica a mixture of a major proportion of silica with minor amounts of other acidic oxides, e.g. of boron, zirconium, vanadium or titanium may be used.  The proportion of silica used may be 0.001-2.5 per cent. by weight of the metal and preferably varies inversely with the specific gravity of the metal. Among the alloys which may be employed are platinum with rhodium up to 50 per cent.; platinum with iridium up to 30 per cent.; platinum with tungsten up to 6 per cent.; platinum with nickel up to 6 per cent. Iron, cobalt, silver and gold may also be constituents of the alloys used.  The compact may be made by sintering or by a fusion and casting process.  Thus it may be made by incorporating silica in the metal powder, compacting by pressure and sintering at 900 DEG C.-1600 DEG C., the sintered compact being then annealed.  Silicic acid sol may be incorporated in finely divided sponge metal powder, the mixture being dehydrated, heated in the range 900 DEG C.-1600 DEG C., fused into moulds and finally annealed.  The initial mixture of metal and silica may be made by mixing silicate and syrupy chloroplatinic acid, coprecipitating ammonium chloroplatinate and hydrated silica gel by addition of ammonium chloride, igniting at 450-600 DEG C. to form sponge powder which is compacted, sintered and annealed. Alternatively the precipitate may be ignited at 900 DEG C.-1100 DEG C., compacted, heated at 1400 DEG C.-1600 DEG C., fused, cast and annealed.  Rhodium may be added to the mixture of platinum and silica or to the precipitated platinum compound and silica, the resulting mixture being reduced in hydrogen, e.g. at 750-1050 DEG C., prior to fusing or at 200 DEG C.-300 DEG C. prior to sintering.  The compact or ingot is annealed for at least 15 minutes at the normal annealing temperature for the metal and may be then hot worked.  After further annealing cold working steps may follow with area reduction of 40-99 per cent. with annealing between each step, e.g. at 550-750 DEG C. For producing wire for catalyst gauze a hot rolled rod of platinum-rhodium containing silica is reannealed at 650 DEG C.-750 DEG C., slowly cooled to room temperature, cleaned by chemical pickling and cold worked in two steps, the first being an area reduction of at least 98 per cent. and the second at least 99 per cent. with between anneals at 650 DEG C.-750 DEG C. for at least 3 hours in an oxidizing atmosphere.  Chemical pickling may be accomplished by use of a dilute aqua regia solution buffered with ammonium chloride or sodium chloride.  The invention is also stated to be applicable to nickel and nickel alloys.
