Abstract: 1,180,636. Radio navigation. DECCA Ltd. 19 Aug., 1968 [18 Aug., 1967], No. 38141/67. Heading H4D. [Also in Division H2] A receiver, for use with a hyperbolic radio navigation system in which synchronized signals of frequency pf and nf are radiated simultaneously from spaced transmitters, each frequency being radiated by only one station at a time, p and n being different integers greater than twelve and f a fundamental frequency, comprises an oscillator at a frequency mf where m is an integer greater than twelve (and may be the same as or different from p and n), means for synchronizing the oscillator with a received signal of frequency pf, a frequency divider providing a time index at frequency f and locked to the oscillator, and a timer responsive to the interval between the time index and a next succeeding time index locked to the nf signals. By integration ambiguities may be resolved. In one embodiment spaced transmitter signals on 1891f, 1887f and 1881f (e.g. f = 37À5 c/s.), Fig. 1, are phaselocked to respective oscillators 14, 15, 16 despite any interruptions in reception (e.g. the transmissions may be deliberately switched). Divider 20 produces an output at f with rectangular waveform and from which an index pulse, shorter than the duration of an R.F. cycle, is afforded by shaper 21 to start a counter 22. The counting is stopped by a squarer 24. Counter 22 is periodically interrogated and the changes in time difference are integrated. A second position line is given by operating switch 26. In another receiver, for stations transmitting on 57f, 56f and 54f, each channel has an oscillator operating at 55f, a gated discriminator controlled from a 55 times divider fed from one oscillator, and integrating meters comparing the phases of the oscillators in pairs, Figs. 2, 3 (neither shown). In a further receiver, Fig. 4, one oscillator only, 55, is utilized for systems in which the transmissions are effectively uninterrupted, phase quadrature outputs are obtained from circuits 60, 65 each of which may comprise the circuit, Fig. 5, which is stated to give substantially 90 degrees phase shift over a wide frequency range: it consists of a transistor 71 affording a constant current to the emitter of transistor 70 the latter being connected to a high input impedance transistor 72 and a capacitative load 73, the emitter of transistor 74 being fed from the collector of transistor 70 and a collector 74 voltage made equal by resistor 75 to that of the voltage at the emitter of transistor 70 but in phase quadrature therewith. Substantially equal amplitudes are obtained but to maintain this when a frequency is changed the magnitude of either load 73 or resistor 75 must be altered.

Abstract: 1,191,725. Packaging-machines. S. LEONHARDT. 21 Aug., 1967 [12 April, 1967], No. 38422/67. Heading B8C. Apparatus for making and filling bags, which may be of plastics, with generally flat articles, comprises a device for opening the bags prior to inserting the articles. A bag (not shown) is brought from the manufacturing device to a supporting table 25 by cords (29), Fig. 3 (not shown), which lie in grooves in the surface 26 of the table when the latter is raised by an electromagnet 27. The raising of the table also causes the opening flap of the bag to be clamped between the table 25 and the near edge 3 of a clamping plate. A slide 8 is now loaded with an article to be packaged, and a contact is thereby operated to start a motor 53 which drives the slide 8, guided by a sleeve 4 on a bar, in the direction indicated by arrow 20. This motion causes a roller 18 to descend a cam surface 19, lowering the rear end 12 of a coverplate 10 on to the article on the slide 8. The movement also frees an arm 42, allowing a spring 39 to open spreader levers 34, (35) which in turn open the mouth of the bag. A blower device (not shown) may also be provided for this purpose. The slide 8 has, at its leading edge 11, two recesses (62), Fig. 3 (not shown) which accommodate rollers (47), 48 when the slide reaches its extreme position within the bag, and the bag and contents are then held between these rollers. A switch 64 is now actuated by a part 63 on the slide, causing the motor 53 to be reversed, whereupon the slide 8 returns to its initial position. At the same time, a chain wheel 57 causes the bag to be withdrawn by the roller (47) in the direction of the arrow 65, the table 25 having been lowered. The switch 66, operated by part 63, stops the motor 53. A contact 67 actuates the mechanism (not shown) for making the plastics bags, and causes a fresh empty bag to be conveyed to the table 25.
