Title: Convertor Steel Making
IPC: C21C5/28
Filed: 1978-12-14
Abstract: In order to keep within tolerable limits the pick-up of nitrogen from the atmosphere by molten steel when making or refining steel by the LD or Kaldo method, the gas space in the steel making vessel is flushed with noble gas after sampling but before reblowing with oxygen. After the vessel 2 has been charged, it is returned to its illustrated upright blowing position; the lance 8 is lowered into the vessel 2 and the molten ferrous metal blown with oxygen. The hood 10 is then raised, the vessel 2 tilted, and a sample taken. If analysis shows that reblowing is necessary, the furnace is returned to its upright position, the hood 10 and the lance 8 are lowered, and argon is passed into the gas space above the molten metal for up to 30 seconds.

Patent GB-2027284-A (GB)
Title: Improvements in electrical generators
IPC: H02K19/28
Filed: 1979-07-20
Abstract: A generator, e.g. an alternator driven by a vehicle engine, has a rotor (10) capable of retaining a small degree of remanent magnetisation. The stator has a winding or windings (11, 11<1>) in which an emf is induced by the remanent magnetisation to provide a current e.g. to charge a battery 16 through a rectifier arrangement (not shown). The battery 16 is arranged to apply current to other windings (14, 14<1>, 15, 15<1>) at an appropriate rotor position to increase the rotor magnetisation, the application of this magnetisation-increasing current being controlled by an element responsive to the position of the rotor. As shown, the rotor (10) carries a small magnet (12) to operate a reed-relay (13) to allow current to flow as desired in the magnetisation- increasing windings (14, 14', 15, 15'). The reed-relay limits current flow to short intervals so that demagnetisation of the rotor is avoided. <IMAGE>

Patent GB-2059292-A (GB)
Title: Growing silicon films on substrates
IPC: C04B41/85
Filed: 1980-09-17
Abstract: The present invention is an improvement to the method of growing silicon films on a substrate by bringing the substrate in contact with molten silicon. The improved growth technique may be classified as an asymmetric mode of growth of silicon on the substrate and is characterized by the substrate being maintained at a higher or a lower temperature than the solidification of silicon in the area of the substrate where the silicon layer growth is taking place, that is in the area of the liquid-solid interface. With a higher substrate temperature the liquid-solid interface is tilted nearly parallel to the substrate surface but inclined at a re- entrant angle, so that the leading edge of the crystalline front is away from the substrate. This provides several advantages including increased growth speed, a nonhomogeneous doping of the silicon layer, that is an impurity concentration gradient and results in a high-low junction at the back surface and gives the back surface field effect. With a lower substrate temperature, say 5-10 DEG C below the freezing temperature of silicon, the liquid-solid interface is tilted nearly parallel to the substrate surface but inclined at a re-entrant angle so that the leading edge of the crystalline front is on the substrate. This provides an advantage of increased growth speed.
