Filed: 1958-06-25
Abstract: 844,720. Fastening railway rails. SKANSKA CEMENTAKTIEBOLAGET. June 25, 1958 [March 7, 1958], No. 20405/58. Class 104 (2). A railway rail fastening device comprises a C-shaped spring steel clamping member mounted with its ends over the rail base and a part of the sleeper to clamp the two together, the mounting being such that the connecting-line between the contact-points is perpendicular to the rail base surface. In the arrangement shown in Fig. 1, the C-shaped clamps 18 are arranged in slits 16 in the sleeper 11 on each side of the rail 13 and one end of each clamp engages a shoulder 17, with or without the hard metal shim 21, and the other end engages the rail base 14 with or without a hard metal shim 19 and an elec-. trically-insulating member 20. The line connecting the points of contact of the ends of the clamp 18 is perpendicular to the upper surface of the rail base 14. The shim 19 may be wedgeshaped in the longitudinal direction of the rail 13 and driven home after the clamp 18 is in position. The insulating member 20 may be integral with or independent of a rubber layer 15 extending under the rail foot 14. In a further arrangement shown in Fig. 4 horizontal recesses 22 provided in opposite sides of the sleeper 23 to receive the lower ends of the clamp 18 have their outer openings located outside a vertical plane through the edge of the adjacent rail flange and extend obliquely towards the vertical plane passing through the centre line of the rail. In a further embodiment shown in Fig. 6, horizontal recesses 24 provided in opposite sides of the sleeper 25, are located entirely under the rail and directed perpendicularly to the longitudinal axis of the sleeper. In a yet further embodiment, Fig. 7 (not shown), the rail is mounted on a crane beam and horizontal recesses are provided on opposite sides of the beam extending at right-angles to the longiditunal direction of the beam and in a common vertical plane. In a further modification, Fig. 9 (not shown), a plain hole provided in the upper end of the clamp receives a screw which bears at its lower end on the foot of the rail and is tightened by a nut engaging the underside of the clamp.

Title: Improvements in and relating to fountain pens
IPC: B43K5/16
Filed: 1929-07-03
Abstract: 328,858. Fritsch, R. A. July 3, 1929. Self-filling reservoir and stylograph pens; inksupply arrangements; nib-sections; nibs; caps.- In a self-filling reservoir or stylograph pen the piston is connected to the nib-section and a tube communicating with the reservoir near its inner end is provided, the arrangement being such that the communication between the ink-feeding duct and the lower end of the reservoir is cut off during the filling operation so that any air trapped in the barrel is expelled through the tube and does not force the ink out of the lower end of the reservoir. The piston 13, Fig. 1, which carries the nib 17 and feed-bar 16, is slidable in the lower end of the barrel 1, being normally held in the outward position by a spring 25 surrounding the tube 6. The nib is held in place by a downwardly-bent projection on the rear end engaging a groove in the feed-bar. The passage in the feed-bar is of zig-zag shape to prevent flooding, the duct actually feeding the nib being of capillary size and the other parts of the passage slightly larger. The inner end of the passage is tapered to facilitate entry of the tube 6 when the piston is moved; alternatively, the tube may be of such a length that it always enters the passage, communication being established between the passage and the lower end of the reservoir by means of apertures in the tube. The upper end of the tube is secured to the end of the barrel and is in communication with the interior of the reservoir. The spring 25 is secured to the reservoir and to the piston in such a way that a key 11 on the piston is normally out of register with a slot in the lower end of the barrel. The inner end of the piston is hollowed out so as to increase the capacity of the barrel and is formed on the outer surface with circumferential grooves adapted to contain ink and form fluid seals. A tapered section on the piston engages during writing with a corresponding part of the barrel to prevent relative movement. In filling, the key 11 is turned into the slot and the piston reciprocated by forcing the nib on to the bottom of the ink well, the enclosed air escaping through the tube 6 and ink duct, and the ink being drawn in along the same passages since the normal passage for ink to the nib is closed when the reciprocation of the piston commences. The inner part of the piston may be in the form of a cup leather 46, Fig. 5, secured to the outer part by a flanged ring 49 and expanded by a spring 51. The cap may be provided with an internal shoulder adapted to seat on the end of the barrel, one or other of these parts being grooved to prevent leakage of ink. In modifications, flooding may be prevented by the provision of a restricted orifice between two chambers in the piston, in which case an ordinary feed-bar with an inclined rear end to facilitate the feed of ink is employed. In other modifications, the spring surrounds a restricted part of the piston.

Title: Improved crystalline alumino-silicate zeolite structures
IPC: B01J20/18
Filed: 1963-05-22
Abstract: Crystalline zeolites of general formula <FORM:1049363/C1/1> where M is hydrogen or a metal of valency c , and X is a number from 1 to 14, are attrited to have an average particle size of less than 0.3 microns.  Suitable zeolites are those known as 4A, 5A, 13X and 13Y, and these may be ground, after washing, in aqueous suspension by ballmilling or by high-frequency vibration. Microspherical particles, i.e. of size 20-200 microns and suitable for use in fluidized bed operations, are prepared from the ground suspension by, e.g. spray drying at 210-500 DEG  F., or contacting with an agitated hot oil at 212-500 DEG  F. and recovering the zeolite by settling, filtration or centrifuging. Macrospherical particles, i.e. 1/30 to 1 inch and suitable for use in fixed bed reactions or adsorption systems, are prepared by mixing the attrited suspension, acting as a binder, with a relatively coarse zeolite, i.e. 1-300 microns, and subjecting the mixture to extrusion and/or drying to give a product containing 10-90% of attrited zeolite.  The relatively coarse zeolite may be the conventional product of the process for forming crystalline zeolites, or may be formed by spray drying the attrited suspension and grinding to the required particle size.  For use as a catalyst, the product may have its soda content reduced to less than 10% by base exchange at 60-150 DEG  F. with, e.g., the cations of Ca, Mg, Al, Sb, Ba, Cd, Ce, Pr, La, Nd, Sm, Cr, Co, Cu, Fe, Pb, Li, Mn, Ni, Ag, Sr, Zn, Sn, Pt, Pd, Mo, V, Rh, or Zr, or H+ or NH4+.  In the case of the microspherical particles, base exchange may take place before or after the conversion to fluidizable particles, and in the case of the macrospherical particles, the zeolites may be subjected to exchange separately or together after formation of the extrudate. The ultimate product is heated at 500-1500 DEG  F. for 1 to 2 hours.

Title: Process for the production of vulcanised polymeric compositions
Inventor: KENDALL CHARLES EDWIN
IPC: C08K5/00
Filed: 1959-06-17
Abstract: Vulcanized polymeric compositions are prepared by heating, in the absence of sulphur, an unvulcanized polymer, not being a polymer or copolymer of chloroprene or its homologues, which contains halogen atoms, hydroxyl groups, ester groups or at least 5 mole per cent of unsaturated monomer units, in admixture with carbon black and up to 20% by weight of the polymer of a Friedel-Crafts type catalyst until the polymer is vulcanized. Specified polymers are natural rubber, polyisoprene, polybutadiene, copolymers of butadiene with styrene, acrylonitrile or methyl isopropenyl ketone, chlorinated polyethylene, chlorosulphonated polyethylene, chlorinated copolymers of ethylene and propylene, polyvinyl chloride, copolymers of vinyl and vinylidene chloride, vinyl chloride-ethylene copolymers, polyglycols, polyethylene adipate and polymethyl methacrylate.  Any carbon black, e.g. furnace black, thermal black or channel black may be used, particularly in amount from 40 to 60 parts per 100 polymer. Specified Friedel-Crafts catalysts are aluminium bromide or chloride, ferric or zinc chloride, antimony pentachloride, stannic chloride, boron trifluoride or trichloride, tellurium dichloride, bismuth trichloride, polyphosphoric acid and p-toluene sulphonic acid.  The catalyst is preferably used as a complex prepared by reacting the catalyst with an organic compound, e.g. dioxane, tetrahydropyran, tetrahydrofuran, trioxane, diisopropylether, cyclohexanone, methyl ethyl ketone, dibutyl sulphide and tetrahydrothiophene in the presence of an organic solvent, e.g. n-hexane.  Alternatively the catalyst may be incorporated in a molecular sieve.  Other vulcanization accelerators, e.g. free-radical curing agents such as dicumyl peroxide may also be present.
