Title: Production of scale-free welded tubing
IPC: B21C37/08
Filed: 1929-11-29
Abstract: 332,869. Air Reduction Co., Inc. Dec. 10, 1928, [Convention date]. Pipes. - Steel pipes or tubes are welded by heating strip-metal or openseamed tubes in a furnace to a relatively high temperature such as above a bright red heat and then progressively welding the edges together, reducing gas being introduced into the interior or exterior of the heated tube or both so as to remove scale or oxide and protect the tube from reoxidation until it cools. A length of open-seamed tube a may be passed through a furnace 2, then through an oxyacetylene, or other oxy-fuel-gas, welding apparatus consisting of a torch 13 and guide, holding, and sizing rolls 9, 10, 11 and thence through a long jacket 16 to which a stream of reducing gas such as illuminating gas, hydrogen or carbon mon-oxide is supplied from a valved pipe 19, to remove scale and oxide from and protect the outside of the tube, the gas escaping either at the end of the jacket or through a tube 18 where it may be burned. The inside of the tube may be de-oxidized and protected by using a torch having a series of fire jets c arranged along and at a short distance from the seam so that a portion of the gas between the rows which contains hydrogen and carbon monoxide and is consumed or partially consumed, passes into the interior of the tube through the open seam as described in Specification 162,431, [Class 83 (iv), Metals, Working]. In a modification a strip a<1> may be fed from one of the reels 20 through a furnace 2a, thence through a skelping die and welding rolls 22 and then through a jacket 16 similar to the first form. In this case reducing gas is supplied to the interior of the tube through a pipe 23. The reducing gas may be arranged to flow either from front to rear or vice-versa or alternately in both directions. A number of abutting seamed tubes, which may be tacked together, may be passed through the machine to weld them in succession.

Abstract: 995,593. Gas chromatography. BODENSEEWERK PERKIN-ELMER and CO. G.m.b.H. Sept. 24, 1963 [Oct. 20, 1962], No. 37542/63. Heading B1L. A stream splitter for placing between the sampler and the column in a gas chromatography apparatus comprises a branch line which by-passes the column and contains a throttling member ad wherein the throttling member is preceded by an absorbent for the sample in the carrier gas so that only pure carrier gas reaches the throttling member. In a specifice embodiment, Fig. 1, carrier gas 10 receives a sample at 12 and part of the gaseous mixture proceeds to the column 16 and detector whilst the remainder goes along line 20. The sample in the carrier gas is adsorbed by charcoal at 22 and the pure carrier gas passes through needle valve 24 to outlet 26. The theory of the device is said to be, that the throttling member may be set to such a position as to give a known splitting ratio of the gas stream when using pure carrier gas and when subsequently a gas mixture is used, the same splitting ratio is obtained because only pure carrier gas reaches the throttling member. The device may be used advantageously with capillary columns.
