Title: Improvements in or relating to methods of manufacturing moulding cast-irons having a predetermined analysis from a first-melt cast-iron
IPC: C21C1/00
Filed: 1966-09-12
Abstract: Blast furnace cast iron is partially purified by a jet of pure oxygen in conjunction with cooling additions of iron scrap or iron oxides (e.g. scale, ore or pre-reduced iron) and pulverulent Fe-Mn is then added to the decanting jet in paper bags to adjust the final manganese content.  Before the oxygen blow the Si content must be at least 0.5% above that desired in the final alloy and this may be achieved by blowing in powdered Fe-Si in a jet of compressed air after which the melt is homogenized by transferring.  Any small correction of the Si content can be made by adding Fe-Si with the Fe-Mn in the last step.  Lime or limestone flux may be added before during or after the partial refining step and in the last case the melt is stirred with a pole to homogenize the cast iron.  After the Fe-Mn addition, Si-Ca in plastic bags, corresponding to 0.1% Si, may be added to the ladle not more than 10 minutes prior to casting.

Title: Improvements in or relating to radar systems
IPC: G01S13/44
Filed: 1958-12-22
Abstract: 844,738. Radar. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Dec. 22 1958 [Dec. 27, 1957], No. 41390/58. Class 40(7). The invention relates to the extraction of information about moving targets, despite the possible presence of fixed targets at substantially the same range, in a radar system employing recurrent pairs of transmitted pulses and directive reception arrangements of the type known as "monopulse". In such reception arrangements the aerial system may consist of four radio horns A, B, C, D, arranged as shown in the focal region of a reflector. The energy received by these horns is combined in various ways in different channels. A "sum" channel is fed by the sum of all the signals (A + B + C + D), an elevation channel receives (A + B - C + D), and a bearing channel (A + C - B + D). The magnitude and sign of the ratio of the output of a difference channel to that of the sum channel gives an elevation or bearing error signal, as the case may be, which can be used to cause the aerial system to track the target. The Specification explains mathematically with the aid of the vector diagram of Fig. 2 (not shown) how, providing the second transmitted pulse closely follows the first, the ratio of the moduli of the difference signal vector corresponding to a moving target and the sum signal vector for the moving target can be obtained despite signals being received from a stationary object at approximately the same range. It is shown that this ratio is equal to minus D/S where #S = ## - ##<SP>1</SP>, #D = ## - #<SP>1</SP>, and- # is the vector sum of the sum signal vectors corresponding to the fixed and moving objects as received after the first pulse of a pair, #<SP>1</SP> is the same vector sum after the second pulse, ## is the vector sum of the difference signal vectors corresponding to the fixed and moving objects as received after the first pulse of the pair, ##<SP>1</SP> is the same vector sum after the second pulse. It is thus possible to track the moving object without interference by signals from the fixed object. In one embodiment apparatus for obtaining D/S consists of a sum path input 1 and a difference path input 2. Mixer stages 3 and 4 transform these inputs to intermediate frequency oscillations amplified at 6 and 7 respectively. Each channel includes a delay line 8 introducing a delay equal to the time spacing of the pulses of a pair. In parallel with the delay line is a phase shifter 12 adjustable to ensure a phase relationship of # between the voltages fed to sum circuit 9. The circuits 9, therefore, have outputs corresponding to the difference vectors #S and #D. They feed a logarithmic amplifier 11 providing an output D/S. A coincidence circuit 10 deriving signals from the two ends of the delay line 8 in the sum channel is used to provide an input to the display 13.
