Patent FI-990302-A (FI)
Inventor: KOSKINEN JUHA TAPIO
IPC: F24F11/00
Filed: 1999-02-15
Abstract: A method and a system for the regulation of ventilation in a welding workshop, in which method the volume of supply air and/or extract air in the ventilation of the welding workshop is regulated. The basis of regulation of the volume is the load imposed on the electric power network by the welding equipment, e.g. the electric power consumed. The system comprises a set of measuring equipment for generating a measurement signal corresponding to the load imposed by the welding equipment on the electric power network. A set of control equipment has been arranged to regulate the volume of supply air brought into the welding workshop via a supply air duct and/or the volume of extract air removed from the welding workshop via an exhaust duct so as to achieve a level of ventilation proportional to the impurity load.

Abstract: 561,174. Annealing; cementation. FITZMAURICE, G. G., and HULL, F. J. K. (representatives of Sandberg, C. P.), and GRAHAM, A. J. W. Jan. 30, 1942, No. 1300. [Class 72] To eliminate hydrogen from the interior mass of a steel article under treatment, the article is either maintained in a container or enclosing device at a constant temperature below that of its critical temperature range for a sufficient length of time to prevent the formation of internal ruptures or is-cooled very slowly from a temperature below that of its critical range in a container or enclosing device, both treatments being applied during the first time that the article is cooling down to atmospheric temperature after it has been originally cast into an ingot. The container may be heated by causing hot gases to circulate around it or for the slow cooling is lagged, and in either case the operation may be carried out in a vacuum or partial vacuum.
Patent GB-652991-A (GB)
Title: Gas turbine power plant
IPC: F02C6/00
Filed: 1948-01-13
Abstract: 652,991. Gas turbine plant. LYSHOLM, A. Jan. 16, 1948, No. 1433. Convention date, Feb. 28, 1947. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 19, 1948] [Class 110(iii)] [Also in Group XII] In a gas-turbine power-plant comprising a compressor, a combustion chamber and an axial flow gas turbine which exhausts into a reheat combustion chamber through a diffluser, the increase in area of the diffuser is obtained substantially entirely by an increase in the diameter of the outer wall of said diffuser. The air compressed in the two-stage centrifugal compressor 61, 62 is divided into two parts by a wall 68. One part passes radially inwardly through an annular slot 69 whilst the other part passes between the walls 68, 70 to the burners 71. After expansion in the turbine 72 the gases are discharged through an annular diffuser 73, the increase in cross-sectional area of which is obtained substantially entirely by the gradual increase in diameter of the outer wall 74, into the reheat chamber 75. The inner wall of the diffuser has an elongation 77a extending into the chamber 75 which causes a zone of turbulence into which fuel is injected at 78. Air from the diffuser 73 may pass directly to atmosphere through a passage 81 and annular slot 82 in the jet nozzle 79. The reheat chamber 75 has additional openings 83 controlled by flaps 84 for control purposes. The turbine may drive a propeller or an additional compressor through gearing 86. To prevent boundary layer separation the diffuser is provided with guide vanes 85 and the equivalent cone angle of the diffuser is of the order of 10 degrees to 15 degrees. The invention may be applied to a plant in which the gases from the reheat chamber pass to another turbine. The Specification as open to inspection under Sect. 91 comprises also the subject matter of Specification 666,062. An arrangement in which an additional compressor which supplies air to a reheat chamber and is driven, by a turbine actuated by the exhaust gases from the compressor turbine is also described. The air inlet to this compressor is annularly arranged facing forwardly on the outside of the nacelle and the exhaust gases from the turbine pass through an inwardly facing outlet. If desired the inlet and outlet may be arranged to discharge through a plurality of openings. Adjustable guide vanes actuated by a speed governor may be provided at the inlet of the compressor. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,239,854. Tubular heat exchangers. WAAGNER-BIRO A.G. 10 Jan., 1969 [15 Jan., 1968], No. 1741/69. Heading F4S. In a tubular heat exchanger comprising a bank of tubes, throttling devices are provided at the fluid inlet ends of the tubes, and at the fluid outlet ends of the tubes are means for measuring the exit temperature of the fluid, the throttling devices being removable to permit them to be replaced or to allow their flow characteristics to be modified so as to achieve a uniform exit temperature of the fluid streams passing out of the individual tubes, or groups of tubes. The throttling devices may comprise nozzles (21, Fig. 4) screwed into individual tubes, or an apertured plate (19, Fig. 3) bolted to the tube end plate (11). The invention is utilized particularly if a tube becomes defective resulting in uneven fluid temperatures at the exit ends of the tubes and hence in uneven heat transfer rates in the tube assembly. Temperature sensing means e.g. thermocouples (24, Figs. 5 and 6) may be provided at the fluid outlet ends of the tubes to detect such temperature variations, whereupon appropriate changes can be made in the throttling devices to restore the uniformity of heat transfer.

IPC: C07C7/06
Filed: 1943-02-09
Abstract: <PICT:0591983/III/1> <PICT:0591983/III/2> Styrene or homologues of styrene are recovered from mixture containing them and benzene hydrocarbons of similar boiling points by distilling the mixture in the presence of (a) acetic acid or (b) ethylene glycol lower alkyl ethers containing not more than six carbon atoms in the lower alkyl group, so as to recover overhead an azeotropic mixture of the saturated benzene hydrocarbons with (a) or (b) and a concentrated bottoms stream of the vinyl benzene.  The mixture may comprise the products produced in the dehydrogenation of ethyl benzene to styrene comprising benzene, toluene, ethyl benzene, styrene and higher boiling components or the styrene fraction obtained from the drip oil recovered in the manufacture of gas or from coal tar distillates produced in the coking of coal and containing ethyl benzene, xylenes, styrene, trimethyl benzenes, olefines and paraffins.  Water is used as solvent to recover the azeotropic agent from the benzenes.  The styrene fraction is distilled in tower 14 in presence of aqueous acetic acid, and the vapours taken overhead are condensed in cooler 22 and passed to separator 24 where the condensate separates into two layers, the lower aqueous acetic acid layer being returned to the still while the upper benzene hydrocarbon layer is further distilled in tower 30 to free it from residual acid which is recycled to cooler 22; xylenes are recovered as bottoms through line 33.  The bottoms from tower 14 are further distilled in tower 36 to remove a ternary azeotrope comprising acid, styrene, and water from which styrene is recovered in tower 46.  Batch-type operation in a modified form of apparatus is also described.  The preferred ethers are the monomethyl, monoethyl, and monobutyl ethers of ethylene glycol and in Fig. 3 a plant using the monomethyl ether is described, the styrene admixed with the ether being introduced into a column 112. Styrene concentrate is recovered as bottoms while the ethyl benzene-ether azeotrope is further distilled in column 130, water being added to the overhead to obtain separation into layers in separator 144 and the upper layer further distilled in tower 152 to recover ethyl benzene as bottom product.
