Patent GB-1039369-A (GB)
Title: Catalytic conversion of ethane to vinyl chloride
IPC: C07C17/154
Filed: 1965-07-19
Abstract: Acetylene and ethylene are produced as by-products in the preparation of vinyl chloride by reacting at 500 DEG  to 750 DEG C. a mixture of ethane, available chlorine and oxygen in the presence of added water and an oxidation catalyst (see Division C2C).  The acetylene may be selectively hydrogenated to ethylene or may be absorbed with cuprous ammonium hydroxide.  Ethylene may be obtained by cooling the reaction product, scrubbing the remaining gas with alkaline solutions, compressing the resultant gas and scrubbing the same with solvents for chlorinated hydrocarbons.ALSO:Vinyl chloride is prepared by reacting at 500 DEG  to 750 DEG  C. a mixture of ethane, available chlorine and oxygen in the presence of added water and an oxidation catalyst; at least one gm. atom of said available chlorine being added per mole of ethane and per mole of oxygen and at least two moles of said water being added per mole of ethane.  The available chlorine may be HCl, Cl2, ethylene dichloride or mixtures thereof. Preferred catalysts, which may be supported on a carrier, are the inorganic oxygen-containing compounds of multivalent metals, especially Fe, Ce, Mn, U, V, Ni, Cr and Co, to which promoters, e.g. inorganic compounds of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, Zn, Cd, B, In, P and Tl, can be added.  Ethyl chloride produced as by-product may be recycled to the process for conversion to vinyl chloride and ethylene also produced as by-product may be converted into ethyl chloride or ethylene dichloride for recycle to the vinyl chloride reaction.  Methyl chloride is a further by-product of the reaction.

Filed: 1936-11-09
Abstract: 484,602. Liquid-fuel burners. FRASER, R. P. Nov. 9, 1936, No. 30497. [Class 75 (i)] [Also in Group XXIX] An oil burner comprises a body 2, Fig. 2, having an orifice 1 through which the oil is discharged for atomization by a stream of gaseous fluid, such as air, discharged as a widebased hollow cone from a conical passage 3 formed between the body 2 and a cap 4 as described in Specification 405,308. The atomized mixture as it issues from a cylindrical extension on the cap 4 is caused to rotate by a whirling converging stream of gaseous fluid issuing from a conical passage 5 between the extension and an adjustable screwed cap 10 on the body 2. The stream is caused to whirl by passing through tangential slots in a ring S which is pressed against the cap 10 by a dished washer 9. The orifice 1 preferably projects beyond the concave front face and rear face of the nozzle. Formation of bubbles is thereby prevented when the oil is withdrawn on stoppage by the means described in Specification 437,185. In another construction shown in Fig. 5 the oil is discharged through radial holes 12a adjacent a baffle 12x on an adjustable plug 12 at a distance from the concave face 2b of the nozzle body 2 and is impinged upon by a converging whirling air current discharged from a chamber 4b between the cap 4 and the body 2. The chamber 4b is connected by tangential holes 4c to the annular air passage 7.

Title: Apparatus for producing tubes with a helical welding seam
IPC: B21C37/12
Filed: 1958-12-23
Abstract: 901,392. Making helically seamed tubing. KUCKENS, A. Dec. 23, 1958 [Aug. 2, 1958; Sept. 17, 1958; Oct. 8, 1958], No. 30519/60. Divided out of 901,391. Classes 83 (2) and 83 (4). A machine for making tubing with a helical welded seam from steel strip fed to a shaper or die extending obliquely to the feed of the strip has the angle between the axis of the strip entering the die and the axis of the tube leaving the die adjustable. Strip 1a from a reel 1 is fed by rolls 18, 19 through guides and between edge trimming cutters 27, 27a and under means 25, for welding the rear end of a strip to the front end of the succeeding strip, to a coiling die 2. To control the gap 1a<SP>1</SP> between adjacent edges of the wound strip a gauge 28 engaging an edge of the strip 1a as it is fed to the die 2, controls a motor 29 which, through rack means 30, rocks a frame 31, carrying the reel 1 and feed means, about a pivot D to correct the entry angle of the strip 1a into the die 2. A pair of feelers 32 on the die 2 engage the edges of the strip which form the welding gap and control the motor 29 instead of the gauge 28. They also control a motor 33 laterally to move the finished tube. In another embodiment, Figs. 7, 9, strip 132 is fed by rolls 130 between lateral guides 128, 129 and top and bottom guide rails 135 to a shaper box housing 101 in which it is coiled by rollers 110, 111, 103, the seam being welded to form a tube 133. The housing 101 is adjustable about a pivot 105 to adjust the angle between the strip 132 and the tube 133. The rolls 103 are adjustable radially on plungers 102 and position themselves obliquely thereon according to the pitch of the coil turns. Fig. 13. They may be replaced by balls 141, Fig. 14. The rolls 110 are similarly self-adjusting. The rolls 111 are mounted on toothed segments 122, Fig. 10, and are rockable thereby by a rack 123 driven by a motor 124 controlled by pressure members 126 engaging the guides 128 so that if strip being fed presses against one guide, the angular position of the rolls 111 is altered to compensate for this. The rolls 110, 103 may be similarly controlled. The rolls 111 are carried by a member 112 urged down by hydraulic means 116 and up by hydraulic means 119, a spirit level 121 being provided. Welding by fusion. The roll carrier 112 supports an internal seam welding arm 114 supplied with weld wire by a motor 115 and, Fig. 11, further supports, on an arm 138, an upper shoe 139 forming a backing for the tube under external seam welding means 140.
