Abstract: The emission of atmospheric pollutants in the exhaust gases of an internal combustion engine having a carburettor is reduced by regulating the composition of the inlet gases, and hence the exhaust gases, of the engine by means of a control device comprising an extra air duct, which has a control valve and bypasses the carburetor, for supplying extra air to the engine inlet, a recirculating duct for recirculating exhaust gases to the engine inlet, a controller which is responsive to signals from an exhaust gas composition sensor installed in the exhaust outlet of the engine and which controls an electrically operated valve in the recirculating duct, and a pressure-sensitive device which communicates with the recirculating duct upstream of the electrically operated valve and which actuates the extra air control valve to regulate the supply of extra air to the engine through the extra air duct.

Abstract: Method and apparatus for filtering a gaseous medium such as welding gas to remove solid particles therefrom. The gaseous medium is passed through a bed having at least two strata of peat litter, wherein the peat litter particles have been screened in such a manner that the first layer as seen in the direction of gas flow comprises particles having sizes ranging from a certain predetermined value and upwards, and the second layer or stratum has particles the sizes of which lay below the said predetermined value. A coating successively builds up in the first layer of peat litter contributing to the filtering effect, whereas the second peat litter layer during this building up period will perform the major part of the filtration.

Abstract: A segmented mold assembly is utilized to cast a turbine engine component having an annular inner wall and an annular outer wall which are interconnected by a plurality of struts or vanes. The mold assembly includes a plurality of sections which are formed of a ceramic mold material and are interconnected at flange joints. A pair of mold sections are advantageously formed simultaneously by repetitively dipping a single pattern in a slurry of liquid ceramic mold material to form a wet coating on the pattern. This wet coating of ceramic mold material is then dried. After a covering of the desired thickness has been built up by repetitively dipping and drying the coatings on the wax pattern, the wax pattern is destroyed. To facilitate separating the mold sections after destroying the wax pattern, at least some of the wet coatings are wiped away in an area between portions of the wet coatings which will eventually form the mold sections.

Abstract: The converter comprises an electronic switching device (SCR1) coupled in series with the primary winding (N1) of a transformer (M) across a rectified AC supply for producing in the primary winding (N1) a primary current pulsating at a desired frequency. Coupled across a secondary winding (N2) of the transformer (M) is a rectifier (D3) and capacitor (C2) arranged, by selection of the value of the capacitor (C2), as a tuned rectifier such that the current in the secondary winding (N2) is cut off by the rectifier action at a low value of the primary current before the switching device (SCR1) is commutated. Such a converter may be used in a television receiver with the transformer (M) comprising the television receiver line transformer and with one secondary winding (N2) supplying the sound circuits of the receiver and a further secondary winding (N3) supplying the picture circuits and, in such application, has the advantage of minimizing the effect of sound load variations upon the size and/or brightness of the picture. <IMAGE>

Abstract: A method and apparatus for longitudinal compressive treatment of a web (16) which employs a novel sheet-form retarding member (40). The working thereof is comprised of a sat of spaced-apart retarding ridges (46) distributed across the width of the portion of the web to be retarded. The ridges are arranged acutely to the longitudinal feeding direction (S) of the web, with initial portions disposed to apply resistance forces (FR) to corresponding portions of web that arrive at the ridges. The resistance force of each ridge resolves into a retarding force component (FS) that resists forward travel of the corresponding portion of web, and a diverting force component (FD) which at least temporarily diverts the path of travel of this portion of web to a direction acute to its original longitudinal direction of movement. The aggregate effect of the set of retarding ridges is to subject the overall web to a substantial retarding action. <IMAGE>
