Abstract: 1474026 Radar MARCONI CO Ltd 19 July 1974 [10 Aug 1973] 37935/73 Heading H4D In a pulse compression radar, of the kind transmitting a bi-phase coded pulse, Fig. 1b, phase detecting the echo signal to give a corresponding series of positive or negative subpulses, passing the series of sub-pulses through a shift register, multiplying the contents of the register stages by respective + 1 or - 1 factors corresponding to the transmitted code and summing the multiplied contents, whereby the sum reaches a peak over a duration corresponding to a compressed pulse, the "correlation" peak is reduced if the phases of the echo sub-pulse are not 0 or 180 degrees w.r.t. the reference phase of the detector, e.g. through Doppler shifts. To overcome this it is known, Fig. 3, to detect the echo ip in phase quadrature to give corresponding in-phase I and quadrature phase Q signals. The signals I and Q are sampled and held at the sub-pulse rate and the samples converted to digital magnitudes /I/ and /Q/. The sum /I/+¢/Q/ or the sum /Q/+¢/I/ whichever is the greater, is used as the input for the shift register. with a sign, as derived from one of the signals I or Q, e.g. I. If however, the echo signal is doppler shifted, Fig. 4, the phase of the subpulses will gradually change, such that when the quadrature axis is crossed, the sign of I for the next sub-pulse (the fifth in Fig. 4) is incorrect. It is proposed to detect the crossing of the quadrature axis by means of the accompanying change of sign of the product (sign I) X (sign Q). Since this also occurs when the in-phase axis is crossed, the simultaneous event /Q/>/I/ is sought, since with practical speeds, the angle the "next sub-pulse" phase makes with the crossed quadrature axis is never more than 35 degrees. A logic circuit performing the detection of the states "change of (sign I) X (sign Q)" and /Q/>/I/ is described Fig. 6 (not shown).

Abstract: 370,000. Discharging dust - bins. KNAPPICH, J., 8, Fr÷lichstrasse, Augsburg, Germany. Dec. 23, 1930, No. 38774. [Class 26.] In apparatus for preventing escape of dust during discharge of a bin into a collector, in which a flexible member 4, Fig. 1, is mounted between and slides between, parallel plates 5, Fig. 4, to seal the space between the mouth of the bin and the wall 6 of the collector, the flexible member is in the form of a spring sheet 4, Fig. 1, which may be constituted by a continuous sheet of flexible material supported by spring bands. The bin 9 is hung on a support 19 by means of a holder 18 and rotated to the position shown in full lines in Fig. 1, so that a member 16 on the hinged lid 15 of the bin engages a member 17 on a cover hood 3 normally closing an aperture 10 in a plate 2 hinged at 7 to the collector, the plate 2 being engaged by a flange 11 on the bin. During the movement of the bin into the collector, the sheet 4 which is pivoted at 13 to, or to a partition carried by, the collector, acts upon a member 12 carried by the cover 3 and so causes simultaneous opening of the cover and lid, whilst the bin is coupled to the plate 2 by the ensuing downward movement of a rod, or rods, 22, each of which is hinged to a member 24 carried by the cover 3 and which has a cam portion 25 which acts to force a spring-urged bolt 20 to engage the flange 11. The cover 3 and lid 15 may be caused to open simultaneously by the provision on the latter of a member 28 which is struck by a projection on the cover 3, the members 16, 17 being in this case dispensed with. In another form, Fig. 5, the sheet 4 serves only for preventing escape of dust, the cover 3 being controlled by the movements of rods 26 hinged at 27, 28, respectively to the collector wall 6 and the cover 3.
