Title: Improvements in or relating to radar systems
Inventor: MORTLEY WILFRID SINDEN
IPC: G01S13/28
Filed: 1962-09-18
Abstract: 1,036,402. Impedance networks; pulse radar. MARCONI CO. Ltd. Sept. 11, 1963 [Sept. 18, 1962], No. 35421/62. Headings H3U and H4D. A radar system comprises an arrangement for converting a long oscillatory train whereof the frequency varies throughout the train as shown in Fig. 2, into a comparatively narrow pulse signal comprises transmission means constituted by a plurality of paths having different delay times between input and output terminals, the delay times being so chosen in relation to the oscillatory train as to correspond to different integral numbers of whole waves whereby differently delayed trains reinforce one another as shown in Fig. 2 to produce a pulse-like signal as shown in Fig. 4. A narrow pulse may be produced from the signal of Fig. 4 by rectification; alternatively by using an oscillatory train whereof the frequencies extend equally on both sides of zero frequency an output as shown in Fig. 3 may be obtained directly. In a first conversion arrangement, Fig. 1, delay means 2 comprises a coaxial cable or an artificial line terminated in its characteristic impedance at 3. The input train is applied at 1 and differently delayed trains are tapped off at points along the line by means such as resistors 5-9. Means for rectifying the output is shown at 10. The conductances of resistors 5-9 may be given a Gaussian distribution so as effectively to impose a Gaussian distribution on the wave train whereby the small peaks to each side of the main pulse in the output may be reduced. In order to enable a shorter delay means to be used, the line 2 may be open circuited so as to become reflecting with discontinuities along its length introduced by resistors 5<SP>1</SP>-9<SP>1</SP>, Fig. 6. These produce reflections which are separated out from the input wave by hybrid means 11. Alternatively series resistors may be inserted at intervals along a reflecting line to produce similar results, Fig. 7 (not shown). In Fig. 8 (not shown) instead of tappings being taken from a common delay means a plurality of delay means connected in parallel between input and output are employed. In Fig. 9 the different delays are obtained by transmission over a radio link via a plurality of spaced reflectors 18. By using a suitable hybrid arrangement a common transmitting-receiving aerial may be used. The reflectors 18, which may be corner reflectors, may be weighted in size or by masking with suitable screens so as to introduce a Gaussian distribution as previously described. The oscillatory train to be converted may be modulated on to a microwave carrier before transmission, the narrow pulse being subsequently recovered by demodulation. Ultrasonic transmission paths may alternatively be used to obtain the various delays.

In the device described a workpiece M is located above a feed roller 37 and between fixed 15 and movable 19 jaws of a vice. The roller 37 is mounted in a vertically slidable carriage 30 which is connected via eccentrics 35a, 35b and levers 45a, 45b, 47, and 59 to a piston-rod 55 of an hydraulic cylinder 49.

In operation, the workpiece M is placed on the roller 37 and advanced to the desired position by operation of a ratchet wrench 41. A valve is then operated to admit fluid to the right-hand end of cylinder 49 and the piston rod 55 is moved to rotate eccentrics 35a, 35b, and lower the roller 37 below the level of a plate 13 on to which the workpiece M is thus lowered. The end of the rod 57 then engages the arm 65 so that the jaw 19 is advanced to clamp the workpiece. After cutting, the valve is operated to admit fluid to the left hand end of the cylinder 49 to permit the jaw 19 to be retracted by a spring 27 and to raise the feed roller 37 and hence the workpiece.
