Title: Partial decarburization of iron and steel
IPC: C21D3/04
Filed: 1965-09-07
Abstract: Steel strip in the form of open coils is partially decarburised to a predetermined level by heating in a muffle furnace in a circulating non-oxidizing atmosphere to a temperature in the range 1100 DEG  - 1600 DEG F., and, when the whole of the charge is at a uniform temperature, introducing water vapour into the furnace atmosphere so that the latter has a dew-point of 20 DEG F. to 120 DEG F.  When the desired carbon level (which must be at least 0.005%) is reached, the introduction of water vapour is discontinued and the strip cooled in a non-oxidizing atmosphere.  Determination of the end-point may be effected by monitoring of the carbon monoxide content of the affluent gases, introduction of water vapour being discontinued when the carbon monoxide reaches a specified value above 1%.  The furnace atmosphere should initially be free of carbonaceous gases, and should contain sufficient hydrogen during the decarburising step to prevent oxidation of iron. Suitable atmospheres referred to are pure hydrogen, dissociated ammonia, 60% nitrogen, 40% hydrogen, or HNX gas formed by partial combustion of a fuel such as natural gas and subsequent removal of carbon oxides.

Title: Aerial arrays for electromagnetic-wave radiation
IPC: H01Q21/26
Filed: 1963-10-02
Abstract: 1,024,367. Aerials. SIEMENS & HALSKE A.G. Oct. 2, 1963 [Oct. 4, 1962], No. 38735/63. Heading H4A. In an aerial array, for radiating electromagnetic waves, in which a plurality of radiators are relatively arranged in a horizontal plane so that the directivity axes of adjacent radiators are directed along different azimuthal bearings, the voltage feed to the radiators is arranged whereby, during operation over a frequency band between frequencies f1 and f2, the phase difference intervals between the voltage fed to said adjacent radiators are other than 360 degrees/n where n is the number of radiators   so arranged at the centre frequency fm = #1+#2/2   and are equal only at a frequency fo, higher than frequency fm. In the arrangement of Fig. 1, which is designed to provide approximate omnidirectional radiation of radio energy over a barrel of 0À85 fm to 1À15 fm, four horizontal dipole radiating arrangements 2, 3, 4 and 5 are arranged around a square mast 1 the outside surfaces of which act as reflectors. Radiator feeder lines 11, 12, 13 and 14 branch out from array feeder 10, to feed radiators 2, 3, 4 and 5 respectively, and are of such length that at the frequency fm the phase differences between adjacent radiators 2 and 3, 3 and 4, and 4 and 5 are all 85 degrees, whilst that between radiators 5 and 2 is 105 degrees. The four phase differences are all equal to 90 degrees at a frequency #o = 1À06 fm. The polar diagram for the array at a frequency of 0À85 fm is shown at 15, and that for a frequency of 1À15 fm is shown at 16. In the arrangement of Fig. 2 (not shown) the decrease in radiation in the quadrant between the directivity axes of radiators 2 and 5 is reduced, by making feeders 26 and 28 of equal length and adding a 180 degrees phase shifting means into feeder 26, and similarly making feeders 27 and 29 of equal length with a 180 degrees phase shifting means in feeder 27, such that the phase differences between adjacent radiators 21 and 22, 22 and 23, 23 and 24, and 24 and 21, are respectively 85 degrees, 95 degrees, 85 degrees and 95 degrees. The upper and lower frequency polar diagrams then become as shown at 31 and 30 respectively. The undulations in the polar diagrams can be further reduced by reorientating the radiators such that the angle between the directivity axes of adjacent radiators is greater for those radiators whose phase difference interval increases with frequency. In addition the radiators may be staggered along their respective sides of the masts such that the distances between adjacent radiation centres is greater for those radiators whose phase difference interval increases with frequency.

In a jig washer, Figs. 1 and 2, having a screen 4 above which the material is separated under the action of pulsating water into a layer L of light components and a layer T of heavy components, the light components are discharged into a trough 2 while the heavy components which move over the screen in the same direction as the light components pass under a member 7 and the trough 2 and are discharged by flowing over a ledge 3. A water or air current may be introduced through a side pipe 8 for controlling the amount of heavy components discharged. The trough 2 may be inclined, as shown, or it may be provided with a screw for facilitating discharge of the light components therefrom. In Fig. 3, the light components are discharged into a trough 2 which has extensions in the longitudinal direction of the jig so that the heavy and light components are discharged inthe same direction. Instead of using a water or air current to control the discharge of the heavy components, the degree of pulsations of the water in the vessel 5 may be controlled or mechanical means, e.g. rotary arms of a discharging wheel, may be used. Two or more jigs may be mounted in series side by side or one below the other to separate more than two components from one another. In another embodiment, Fig. 6 (not shown), three components are separated from one another, the light and medium as in Figs. I and 2, and the heavy by a bucket lift.
