Title: Frequency discriminator
IPC: G01S13/60
Filed: 1964-11-23
Abstract: 1,028,060. Frequency and phase discriminators; measuring speed by sound waves. BENDIX CORPORATION. Nov. 23, 1964 [Dec. 13, 1963], No. 47612/64. Headings H3A and H4D. Doppler frequency shift in a carrier frequency pulse is measured by applying the pulse over a frequency sensitive phase shift network 15 and also directly (without delay) to a bi-stable phase detector 32-35 whose D.C. output, smoothed, indicates the frequency shift. The bi-stable circuit comprises a pair of crosscoupled PNP transistors 34, 35 and a pair of cross-coupled NPN transistors 32, 33, the emitters of each pair being connected to equal positive and negative voltage supplies 41, 40 and corresponding collectors of each pair being directly connected. Zero phase shift from the phase shift network 15 results in oppositetype transistors 31, 30 being conductive during alternate half-cycles and actuating the bistable circuit so that a symmetrical square wave is produced from the common collector junction of transistors 35, 33, but changes of phase with frequency cause the conduction interval of transistors 35, 33 to vary oppositely so that an average D.C. output results of magnitude and polarity, indicating the magnitude and sense of the carrier frequency shift, e.g. on an oscilloscope and the duration of the applied carrier pulse may also be indicated. The phase shift network 15 may comprise ten sections having in the series arms an inductor L 1k  and capacitor C 1k  series resonant at the discriminator centre frequency f 0  and in the shunt arms a capacitor C 2k  and inductor L 2k  parallel resonant at the same frequency f 0 , the arrangement forming a constant - K filter with zero attenuation over a pass-band covering the maximum and minimum frequency deviation and a linear phase-shift over this band; but with the resultant total delay less than the pulse duration. The Doppler pulses may also indicate information by their width. The invention is applied to a sonar system.

Abstract: 1332504 Transferring cigarette packets from and between endless conveyers HAUNIWERKE KORBER & CO KG 16 Oct 1970  [22 Nov 1969] 49302/70 Heading B8A Cigarette packets &c. 102 on a conveyer belt 101, are transferred to either of a pair of conveyer belts 119, 126, by a rotary disc 103, the selection depending on the presence or absence of a predetermined characteristic. The latter has suction apertures 109 backed by suction chambers 111, 129. If suction is not applied to the chamber 129, an article picked up by the disc 103 as it passes under the bore 111, is dropped on to the belt 119. When suction is applied to the box 129, the article is carried round to the belt 126. Control of the suction to box 129 is effected by a valve 113 operated in response to a signal from a decade counter 137. The latter is connected to a reflection light control unit 136. Thus if conveyer 119 leads to a packing machine, every tenth packet may be diverted to conveyer 126 for quality control purposes. In this ease the predetermined characteristic is the position of the packet in the movin stream. In another arrangement, alternate packets may be transferred to conveyer 119 while the remaining packet are fed away on conveyer 126. If the input conveyer 101 is conveying wrapped packets, the unit 136, which may be responsive to colour, may be used to detect unwrapped packets. In a modification (Fig. 1, not shown) the belt 126 may be formed by a continuation of the belt 101.
