Title: Method of, and apparatus for, connecting pipes end-to-end
Inventor: AINSWORTH LESLIE
IPC: B29C65/00
Filed: 1969-03-31
Abstract: 1293371 1293371 Pipe couplings REDLAND PIPES Ltd 25 March 1970 [31 March 1969] 16682/69 Heading F2G A pipe coupling has a tubular member in the form of a sleeve 13, Fig. 1, spaced radially from ends 3, 4 of pipes 1, 2, and sealing rings 7, 8 and 11, 12 are provided to define the axial limits of annular spaces 20, 21 filled with a hardenable composition which bonds to the sleeve and pipe ends to provide a liquid-tight seal. As shown in Fig. 1 the tubular element 13 surrounds the pipe ends 3, 4, but alternatively it may surround one and be inserted in the other, or be in the form of a ferrule inserted into both. Grooves 5, 6 in the enlarged pipe end 3 hold the sealing rings 7, 8 in place and the flowable hardenable composition is forced through a hole 14 in the underside of the tubular member until the annular space 20 is filled and the composition seaps out of a diametrically opposed hole 15. In this embodiment neither pipe need be longitudinally displaced during assembly since first the sleeve 13 may be placed over the pipe 1 in position 13a, the pipe 2 aligned and then the sleeve slid axially into its final position. The tubular member may alternatively be formed with two integral parts of different cross-sectional area, Fig. 3 (not shown), the wider tubular portion (13d) being in sealed engagement with one pipe end (3c) as described above, and the narrower portion (13e) being inserted into an enlarged socket (4c) on the other pipe which is sealed thereon again as above. The tubular element may take the form of an internal ferrule 13b, Fig. 2, in which case only one ring of hardenable composition is required to secure the joint. A temporary ring 23 is arranged around the socket ends 3b, 4b of the pipes to span a gap left between the pipes and the composition is introduced through the lower of two diametrically opposed holes 14b, 15b in the ring 23 to fill an annular space 20b between the tubular element and the pipe ends and bounded axially by sealing rings 8b, 11b.

Title: A method of flame drilling or channelling of a solid body and a burner for use in such a method
IPC: F23D14/34
Filed: 1969-03-31
Abstract: 1,224,453. Blasting. BROWNING ENG. CORP. 31 March, 1969 [29 April, 1968], No. 16732/69. Heading B3D. [Also in Divisions B5, E1 and F4] Air can satisfactorily replace oxygen as the oxidant for the burning of liquid fuel, e.g. kerosene, supplied to the combustion chamber 45 of a burner for use in the flame drilling or channelling of a body, e.g. rock or soil, if the pressure in the chamber is greater than 150 p.s.i.g. The cutting action of the flame issuing from the outlet nozzle 47 of the burner can be improved by adding, preferably in the combustion chamber, abrasive particles to the flame gases. Allowance of axial and lateral expansion of the wall 33 of the combustion chamber relative to the outer casing 31 of the burner is facilitated by anchoring only the inner surface of the lower end of the wall to the outer casing via the nozzle and an annular closure plate. Cooling of the wall and casing is improved by a deflector 32 secured to the upper end closure of the combustion chamber. The deflector causes air to pass down the casing and then up the outside of the wall of the combustion chamber before entering the chamber.

Title: Improvements in Bakers' Ovens.
IPC: A21B1/48
Filed: 1917-11-16
Abstract: 120,631. Baker & Sons, J., Kirman, H., and Taroni, C. E. Nov. 16, 1917. Bakers' ovens.-Gaslieated ovens, of any type in which the sole is n o t continuously passed through the e oven, are arranged so that the heat may be uniformly distributed, by moving the sole mith relation to the gas burners or the gas burners with relation to the sole, or by both these methods, by any convenient means. As shown in Fig. 1, a Ý1exible sole b is heated as usual by upper and lower. gas burners b<3>, b<4>, and it receives an intermittent movement alternately backwards and forwards by means of a driven worm c on a shaft having an eccentric c<2> connected by rods c<3> to oppositely-set pawl- and-ratchet mechanism c<5>, c<6> at each end of the oven, and from which motion is communicated alternately in opposite directions by spur wheels d, d' and end sprockets b<1> carrying the flexible sole. When it is desired to charge or discharge the oven, one of the sets of pawl-and-ratchet mechanism, for example, that of the charging end, is disconnected bv means of a clutch and lever, so that the sole receives an intermittent movement in one direction only. In the case of an oven having a draw-plate, the plate is intermittently oscillated by connecting a bracket beneath the plate to lever mechanism, alternately moved in opposite directions, .by an eccentric driven from a main shaft. When it is desired to withdraw the plate, the connexion between the lever and the bracket is removed by means of a hand-lever. When the sole is fixed, the burners are oscillated. as shown in Fig. 6, by connecting the two series of burner tubes i, i<1> by bars J<1> which travel on wheels k over tracks k', and. which are connected to the arms l of a rock shaft l' which is operated from a driving shaft b<4> by reducing gearing as indicated. The sole may be oscillated from side to side by means of eccentrics connected to the sole by links extending through the oven wall, the eccentrics being carried by a shaft driven through reducing gear from the main shaft. In a modification, the upper set of burners is fixed, but the lower set and the sole are both oscillated sideways by an arrangement corresponding to that shown in Fig. 6 for both sets of burner tubes. In another modification, the sole receives movement in an elliptical path by mounting the sole on brackets s<1>, Fig. 14, having ball bearings s<2>, and providing a pair of covers t which are pivoted at their ends t' to the sole and slotted at t<2> to embrace fulcrum pins t<3> carried by a cross bar t'. The other ends of the levers are each connected to an eccentric u mounted on a bracket u<1>, movement being imparted simultaneously to both eccentrics by means of bevel gearing u' driven from the main shaft u<3>, Movement of the sole or burners in a circular path is disclaimed.

Title: Improvements in arrangements for lubricating top parts of cylinders of internal combustion engines
IPC: F01M1/16
Filed: 1945-07-03
Abstract: 607,960. Lubricating. SOC. D'ETUDES DE CARBURATION POUR L'AUTOMOBILE ET L'AVIATION. July 3, 1945, No. 16906. Convention date, June 17, 1941. [Class 12 (iii)] For a regulated supply of lubricant to the top parts of the cylinders of internal come. bustion engines, oil is passed to the engine admission pipe 22 downstream of the throttle 23 and under the control of a regulating device comprising a main oil passage, the opening of which increases with the decreasing pressure difference from atmospheric pressure arising in the admission pipe with a more open throttle when the engine is on load, and a parallel oil passage of fixed opening (after initial adjustment). In the arrangement shown, this pressure difference acts on a piston 15 to move a needle valve 19 towards closing position so that at low engine load (closed throttle) the supply of lubricant is reduced. Parallel with this valve is a fixedly adjusted needle valve 14, while there is a screw-stud adjustment 17 to limit the amount of opening of the first needle valve 19. This needle valve combination in conjunction with the variation of pressure difference in the engine admission pipe 22, depending on the throttle setting, gives a properly regulated oil supply increasing with engine load. The oil is supplied from a reservoir 1 and passes to the needle valve combination through a visual flow indicator 8 on the dashboard, the flow being rendered visible by emulsifying the oil with air admitted at a fine hole 6 in the piping 5 ascending from the bottom of the reservoir 1.

Abstract: 1318324 Carbon microspheres from pitch KUREHA KAGAKU KOGYO KK 26 May 1971 [29 May 1970] 17330/71 Heading C1A [Also in Division C5] Hollow microspheres of pitch having a diameter of 5 to 500 Á which are infusibilized and carbonized, are made by thoroughly mixing a highly aromatic hard pitch (S.P. 60‹ to 350‹ C.) with an organic solvent having a low B.P. (not above 150‹ C.) and dispersing the mixture in water in the presence of a protective colloid to form the spheres, which are foamed by rapid heating, e.g. in an air stream, to a temperature sufficient to vaporize the solvent in the spheres and near the S.P. of the pitch but insufficient to cause the spheres to collapse or adhere to each other. The pitch must have a nitrobenzeneinsoluble content between 0 and 25%, and a H.C. atomic ratio in the range 0À2 to 1À0, suitable pitches being obtained by the removal of low molecular weight or oily components from coal tar or the by-product tars formed during the production of olefins by heating petroleum hydrocarbons to 700‹ to 2500‹ C. for 0À001 to 2 seconds. Solvents mentioned include benzene, toluene, xylene, carbon tetrachloride, chloroform, ethylene dichloride, tetrahydrofuran, butyl ether, pentane, hexane, cyclopentane and cyclohexane, and they may form 0À2 to 10% b.w. based on the pitch. A homogeneous mix is formed by heating and stirring, and it is added to a mixture of water and colloid. After stirring and cooling, the spheres are removed, e.g. by centrifuging, from the water. Colloids, which may form from 0À01 to 5% b.w. of the water, include partially saponified polyvinyl acetate, polyvinyl alcohol, methyl cellulose, carboxymethyl cellulose, polyacrylic acid and its salts, starch, konjakflour, gum arabic and gelatine. Pitch to water weight ratios range from 1 : 1 to 1:3. After being foamed, the hollow spheres are infusibilized (to prevent melting during carbonization) by treatment with an oxidizing gas at elevated temperature or a liquid, e.g. nitric acid, sulphuric acid, or a solution of chromic acid or potassium permanganate at room temperature, and carbonized for from 10 to 200 minutes at a temperature in the range 600‹ to 2000‹ C. in a non-oxidizing atmosphere.
