Abstract: 638,189. Railway &c. rails ; rail joints ; securing rails to sleepers. SOC. D'ETUDES, DE BREVETS ET DE RECHERCHES SEBRE SOC. ANON. March 23, 1948, No. 8573. Convention date, April 4, 1947. [Class 104 (ii)] An invertible rail for railways or tramways, or for monorail or similar tracks is provided with three treads of which two are used as continuous supporting members while the third forms the running tread, so that by rotating the rail about its longitudinal axis the treads can be brought successively into the position of a running tread. Fig. 1 shows a rail with treads 2, 3, 4 disposed on continuous webs 5, 6, 7 at an angle of 120 degrees to each other, and supported at intervals by bedplates 9 formed with a central frog 12 providing a bearing for the core of the rail over a contact surface 11, a lateral cheek 10 being provided at each side of the frog to abut against side faces of the supporting treads 3 and 4. The rail is anchored by chairs 13 with their upper edges bearing against the other side faces of the treads 3, 4 and held by bolts which have their heads located in sockets 14 on the bedplate. Fig. 3 shows a modification wherein the webs of the individual treads are dispensed with and the bedplate is given the profile of the space between the side faces of the treads. The chairs or fish-plates 19 are attached to the sleepers in any suitable manner and are formed with longitudinal recesses to receive tightening keys 23 each provided with a lateral lug at the outer end to receive a connecting-bolt 24, Fig. 5 (not shown), which screws into an adjacent stiffening web 20 in the fish-plate. The rails can be connected to rails of normal section by cast junction rails which have a profile varying continuously throughout their length, from that of the rail shown in Fig. 1 or 3 to that of the normal rail.

Filed: 1976-03-04
Abstract: 1522744 Monitoring rail surfaces SPENO INTERNATIONAL SA and FRANK SPENO RAILROAD BALLAST CLEANING CO Inc 4 March 1976 [14 March 1975] 08630/76 Heading G1N The vertical undulations of a rail surface are measured by an accelerometer carried on a rail vehicle, the resulting signals being integrated, filtered and recorded as a function of distance travelled. The signals from accelerometer 4 (Fig. 3) are amplified at 6 and fed through a band pass filter 7 to be double-integrated at 12. The vertical displacements thus obtained are rectified at 13, averaged at 15 and recorded at 20. Large pulses due to e.g. joints in the rail, are eliminated by filter 19 and counted at 22. The pass band of filters 7, 19 is automatically controlled by a speed signal derived from circuit 8. The frequency of the undulations is determined at 25 by counting the zero cross overs of the signal from integrator 12. This is divided at 27 into the speed signal to determine the wavelength of the undulations. The noise developed is picked up by a microphone 31 and recorded at 41.

Title: Oxidation process
IPC: C07C63/00
Filed: 1957-03-18
Abstract: Organic compounds having at least one carbon to hydrogen bond are oxidized by heating them under superatmospheric pressure in a molar excess of water with elemental sulphur at a temperature above 500 DEG F.  The reactants may be in liquid and/or vapour phase. A molar ratio of water to organic compound of at least 20:1 is preferred. Apparatus for conducting the oxidation continuously is described.  In an example, a mixture of toluene (1 mol.) and water (100 mols.) is charged into an autoclave containing 1 sulphur (3 mols.) in a glass tube.  The autoclave is sealed, heated to 625 DEG  F. and then shaken to mix the sulphur with the contents of the autoclave.  Heating and shaking are continued for 90 minutes, the autoclave is cooled, hydrogen sulphide is bledoff and the product filtered, dried and distilled to give benzoic acid.  In further examples the following compounds are oxidized to acids: o-, m- or p-xylene to a mixture of o-, m- or p-toluic and ortho-, iso- or tere-phthalic; propane or propylene to a mixture of acetic and propionic; p-toluic to terephthalic; acetophenone to benzoic; and diisobutylene to a mixture of unspecified acids. Various other oxidations are specified in a table, including cyclohexane to phenol, a -methylnaphthalene to naphthoic acid, styrene to benzoic and phenylacetic acids, a -methylstyrene to a phenylpropionic acid and tetrahydrofuran to acetic, propionic and succinic acids.

Abstract: 579,032. Ammunition &c. receptacles. TREPUR PAPER TUBE CO., Ltd., WARBURTON, R. E. L., and KANE, W. March 24, 1938, No. 9011. [Classes 18 and 21] [Also in Group XXI] A ring for supporting an ammunition shell or like body in a container is formed in two complementary sections fitting together so that relative axial movement of the sections permits one of the sections to expand and release the body being supported or to contract and hold said body. As shown, the ring sections 1, 2 are formed with mutually engaging inclined surfaces 3, 4, the inner surface 6 of the inner ring section 2 engaging the tapered portion of the body to be supported. An annular flange 7 on the section 2 projects into an annular recess 8 in the section 1 and normally rests on the flat base 9 of such recess to which it is loosely secured by bolts or rivets 10 screwed into the section 1, passing through radial slots 12 in the flange 7 and extending above the surface of the flange so that the heads 11 limit the separating movement of the ring sections. The outer surface of flange 7 has a diameter slightly less than that of the recess 8, the wall of which is slightly inclined and one or more slots 13 are made in the section 2 to enable it to yield circumferentially. The composite ring is supported for axial movement in an annular recess formed between tubular elements 15, 16 in a cylindrical ammunition container 14. When the article is inserted into the container, the tapered portion thereof comes into engagement with the tapered inner section 2 and is securely held thereby, the ring being bedded at the base of the container recess as shown. On withdrawal of the article, upward axial movement of the composite ring into engagement with the upper wall of the container recess tends to strip the ring from the tapered portion of the body and further axial movement of the inner section 2 separates the ring sections at their inclined meeting surfaces, the angle of the latter and the clearance between the flange 7 and the adjacent inclined wall of the recess 8 then permitting the section 2 to expand sufficiently to free it from the tapered portion of the body.

Filed: 1924-04-10
Abstract: 214,262. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. April 11, 1923, [Convention date]. Vacuum tubes.-In a tube in which an emission of secondary electrons is produced by bombardment of one or more electrodes by primary electrons, the surface emitting secondary electrons consists of a material having a Richardson constant less than 3 volts, as, for instance, the alkali and alkaline earth metals, magnesium, beryllium, titanium, scandium and certain metallic compounds such as copper oxide and the oxides of the alkaline earth metals. It is stated that a tube of this kind having a negative resistance characteristic will operate with a voltage of 30 between the anode and cathode. The material should be preferably a poor conductor of heat, and may be incorporated in or deposited on an electrode of tungsten, molybdenum or nickel. A compound which may be decomposed by heat to form the active material may be applied to the electrode before or after mounting in the tube. For example, barium oxide applied to an electrode may be heated during exhaustion of the bulb, so that nitrogen is driven off and barium is oxidized to barium oxide. In another method the material is deposited from an incandescent cathode by evaporation or disintegration. The vacuum is preferably high, but when the tube contains gas, ionization should be avoided by using voltages below the ionization voltage of the gas. In the tube shown for generating oscillations in a circuit 8, 9 the active material is contained in the anode 4, and a grid 3 between the anode and an incandescent cathode 2 is maintained by means of a battery 7 at a higher potential than the anode. The anode may be of cylindrical shape and of circular or ellipsoidal section so that any material " sputtered " from the active inside surface may be deposited elsewhere on the surface.
