Title: Welding apparatus
Inventor: HALE JAMES
IPC: B23K28/02
Filed: 1969-04-12
Abstract: 1,272,099. Welding by fusion; welding by pressure. TUBE PRODUCTS Ltd. 16 April, 1970 [12 April, 1969], No. 18841/69. Heading B3R. Welding apparatus e.g. for continuouslyforming longitudinally-seamed tube, comprises a welding head H and means T for monitoring the thickness of the material to be welded such that the electrical power input to the head H is controlled automatically in dependence upon the measured thickness. The power input to the head H can also be controlled in dependence upon the measured speed of the material or welded tube. As shown, an electromechanical transducer T has a strip-engaging feeler. An output from the transducer is suitably processed by an amplifier A and converter C, and a signal proportional to the measured thickness passed to a multiplier D. A meter M displays the thicnkess. Also, a tachogenerator G has a strip-engaging roller. An output from the tachogenerator passes to the multiplier D via a circuit SQ which gives an output proportional to the square root of its input signal. The output from the multiplier D passes via an amplifier A<SP>1</SP> and manually-operable attenuator F, which acts as a trimming device under operator control, to a servo unit V which controls the power output of supply unit P. The head H is preferably an RF induction head but could be a low frequency induction head, or a resistance welding head with electrodes in contact with the strip on each side of the gap between the egdes, or an arc welding head with an automatic feed for consumable electrode or filler rod. 1,272,128.

IPC: C10K3/04
Filed: 1930-06-21
Abstract: In a process for producing a combustible gaseous mixture free from carbon monoxide and consisting mainly of methane and hydrogen, from gases such as coal gas, producer gas, or water gas, the gases are treated to a contact process in two successive stages.  In the first stage, the major part of the monoxide is transformed by steam into carbon dioxide and hydrogen, and in the second stage, the remaining monoxide is transformed into methane and water vapour by hydrogen. The catalyst used in the first stage consists of an oxidizing agent such as chromiferous iron in conjunction with substances capable of setting free from the reagents the elements of water and preferably substances of large superficial area such as active charcoal or lignite coke.  Similar substances are used in the second stage in conjunction with a catalyst such as nickel, as for example, thoria, alumina, chromic oxide, active charcoal, or lignite charcoal.  The original gas, saturated with steam at about 50-80 DEG  C. is heated to about 500-550 DEG  C. before passing into the contact towers.  In the second stage a temperature range of about 180-250 DEG  C. may be used.
