Abstract: 1,044,630. Feeding webs. D. AYRES JONES & CO. Ltd., and D. A. JONES. Sept. 20, 1963 [Sept. 25, 1962], No. 36382/62. Heading B6B. A web of polythene or other thin limp material is fed by rollers 3, 4, Figs. 1, 7, 8, so that its leading edge passes between knives 33, 34, blowers 46, 48 directing air forwardly and towards the web to keep it in a floating condition. The roller 4 is driven from a cam 25 on a shaft 26 through a rack 17, adjustable at 18 by a hand-wheel 20 for length of feed, a clutch operated by a solenoid 18 being intermittently engaged so that the roller 4 only rotates in forward feed direction. Air is also supplied to a casing 50 whence it passes forwardly into a casing 51, producing suction at the end of the casing 51 which guides the end of the web into said casing, through which it passes in a floating condition due to the air streams therein. When the web has passed between a table 36 and a bar 35 by a predetermined amount, the latter clamps the web to the table. The knife 33 is then moved downwards, co-operating with the stationary knife 32 to sever the web. The roller 4, knives and bar 35 are operated in timed relationship by cams on the shaft 26, and the air blasts are controlled in timed relationship with the above-mentioned mechanisms by a solenoid, which may be the solenoid 18: The table is then lowered so that the web is suspended vertically from the bar 35 and wrapping means then pushes an article, such as a loaf of bread, on to the table so as to be wrapped by the web.

Title: Secondary radar systems
IPC: G01S13/78
Filed: 1975-08-27
Abstract: 1485880 Secondary radar systems; interrogator-responder systems FERRANTI Ltd 27 Aug 1975 [28 Aug 1974] 37507/74 Headings H4D and H4L A secondary radar system includes an interrogator station, Fig. 2, and at least one cooperating transponder station, Fig. 1, which transmits a specially coded response signal which is detected in the interrogator station. A pulsed interrogation signal is generated at 21, Fig. 2, and transmitted from 20. A radar receiver 10 in the transponder is selectively responsive to this signal to trigger a signal generator 11 to generate, e.g. a 20 Ás burst of r.f. oscillations, or, may in an alternative embodiment (not shown) generate a D.C. level which is subsequently modulated. This signal is fed to a surface acoustic delay line 12 from which, for example, 20 taps are taken whereby twenty 1 Ás bursts of r.f. signal are fed through separate channels in phase shifter 13, wherein, according to a code word CW, arranged to have an even number of "ones" and "zeros" a # radians phase shift is introduced respectively to those channels corresponding to a "one" in code word CW. These signals are combined in amplifier 14 to be transmitted sequentially in a 20 Ás pulsed signal from transponder transmitter 15. The pulsed signal is received in interrogator receiver 23 and fed to an identical tapped delay line 24, which on complete receipt of a 20 Ás pulse provides at its tapping points signals corresponding to the phase shifted 1 Ás signals. These are applied simultaneously to two phase shifters 25 and 26 identical to 13. In 25, the code word CW is again applied to the signals whereby all the phase-changed bits have their phases reversed again and, on summing these signals co-temporaneously in amplifier 27, an output signal is produced and fed to threshold detector 29. This signal only exceeds the predetermined signal when all the 1 Ás bits add in phase corresponding to detection of the transponder response signal. In phase-shifter 26, a code word CW<SP>1</SP> is applied which corresponds to CW and in addition reverses the phase in every other channel, whereby on the instantaneous presentation of the transponder signal 1 Ás bits to the twenty channels of phase-shifter 26 an equal number (ten) of zero shifted and # radians shifted signals are produced, which, when summed in amplifier 28 mutually cancel. Threshold detector 31 responds to this zero output, and comparator 30 is arranged to give an indication, when response signals are simultaneously supplied by detectors 29 and 31, of receipt of a transponder response signal. It is stated that the code word CW may be changed at will to increase the security of the system.
