Title: Improvements in or relating to the surface treatment of steel
IPC: B21B45/04
Filed: 1963-07-30
Abstract: 1,028,776. Blasting. BELL INTERCONTINENTAL CORPORATION. July 30, 1963 [Aug. 20, 1962], No. 30176/63. Heading B3D. Hot worked steel, e.g. sheet or strip, is treated in preparation for a subsequent cold working operation, e.g. rolling, by blasting it with steel shot and then blasting it with grit. The first blasting removes more than 95% of the mill scale, while the second blasting removes embedded particles of scale, particles of workhardened metal and amorphous iron thus avoiding the formation of smut in the coldworking operation. Both stages may be performed by centrifugal wheels directing on to both surfaces of the steel. The grit is preferably steel grit; non-ferrous or non-metallic grits, e.g. sand or aluminium oxide may be used instead. The grit may be suspended in liquid. The steel shot may have an average diameter of 0À01-0À039 inch and a hardness of 45-55, preferably 48-55, Rockwell C. The grit may have largest dimensions of 0À007-0À017 inch and a hardness of 55-65, preferably 58-64, Rockwell C. 12 gauge low carbon steel is hot rolled and then passed at 80-100 ft./min. through a strip cleaner having centrifugal blasting wheels directing shot of 50 Rockwell C at about 1800 lb./min. on each side of the strip; the strip then passes through a second cleaner having centrifugal blasting wheels directing shot of about 60 Rockwell C at the same abrasive flow rate.

Abstract: 754,077. Automatic speed and frequency control systems. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIAL D'USINES A GAZ. Oct. 20, 1954 [Nov. 20; 1953], No. 30238/54. Drawings to Specification. Class 38 (4). An alternator is driven by a synchronous motor through a differential-gear having one element driven through a non-reversible worm by an auxiliary motor controlled by the frequency cross-signal. To permit the use of a low-power auxiliary motor, the synchronous motor is arranged to drive the alternator slightly faster than the required frequency, so that the auxiliary motor always runs in a direction to reduce the speed. As described, the alternator frequency is compared in ring demodulator with that from a standard oscillator. The output supplied to a ring modulator to control the " firing " of a pair of thyratrons through the auxiliary motor is energized.

Abstract: 1,183,012. Air rectification process. McDONNELL DOUGLAS CORP. 28 June, 1968 [5 July, 1967], No. 31093/68. Heading F4P. Product nitrogen is withdrawn from the head of an air rectification zone 22 having a saturated compressed - air' inlet 20, and oxygen-rich liquid is withdrawn from the base of the zone 22 at 36, flashed at a valve 38 and passed through a passage 42 in heat exchange with zone 22 thereby condensing reflux in 22, and the so-vapourized oxygen-rich gas is withdrawn from passage 42 heated in a passage 46 in a heat exchanger 18 for cooling the feed air and is expanded in a turbine 50 and passed through a passage 56 in heat exchange with zone 22 thereby providing reflux therefor after which the so-warmed oxygen-rich gas is withdrawn at 58, warmed in passage 60 of exchanger 18 and discharged as waste at 62. Product nitrogen is withdrawn at 26 in the gaseous phase and at 28 in the liquid phase, and when the ratio of gas to liquid is high the oxygen-rich liquid withdrawn at 36 has a high oxygen content and the flow rate and pressure ratio of the workexpansion at 50 are low. Conversely when the product nitrogen has a high liquid to gas ratio the oxygen-rich liquid has a low oxygen content and the flow rate of the mixture and the pressure ratio of the work expansion are high. The zone 22 and passages 42, 56 are located in a single column 24 and extend throughout its height thereby effecting non- adiabatic differential distillation of the cornpressed air in zone 22. In a modification the oxygen-rich gas leaving the warm end of passage 46, Fig. 2 (not shown), is recompressed and after cooled before being expanded at 50.
