[Class 31 (i).] Rotary blade machines.-Cutting apparatus for newspaper printing presses and like machines comprises a pair of co-operating cylinders 10, 11 performing a cutting operation at every revolution of one of the cylinders 10, the cutting devices being arranged so that successive cuts take place on opposite sides of a diameter of the cylinder 10. The cylinders 10, 11 cut off from the printed web a sheet which is taken by pins 31 on the cylinder 10 and associated on the cylinder 11 with the succeeding cut sheet in the usual way prior to folding. In the construction shown, the cylinder 10 carries the cutting blade 14 and the coacting block 12 is mounted on the folding cylinder 11. The blade 14 is secured in a box member 15 pivoted at 17 in a recess 16 in the cylinder 10 and oscillated so that the blade 14 coacts alternately with spaced grooves 13, 13<1> in the block 12 and thus cuts off sheets of slightly different lengths, the shorter sheet being the inner of the two associated sheets when they are folded. The mechanism for actuating the box 15 comprises a ring 22 on the end of the cylinder 10 and slotted at 21 to engage a projection 20 on the box. An additional slot has sloping sides engaged by rollers 26 on a crank arm 23 fixed to a spindle 24 rotatable in bearings on the cylinder 10. A roller 25 projecting from the outer face of the arm 23 runs in the grooved cam 29 operating the collecting pins 31 so that the crank arm 23 and consequently the ring 22 and box 15 are oscillated to vary the position of the knife 13. The cam 29 is rotated at half the speed of the cylinder 10 by a gear chain 38, 36, 37, 40, the gear 40 being integral with the cam 29, and the gears 36, 37 being relatively fixed and rotatable on an eccentric stub-shaft 46 by which they can be moved to render the cam drive inoperative. In a modification, two cutting blades are mounted on the folding cylinder 11 and spaced slightly more or less than a semicircle so as to coact with two grooves in a coacting block carried by the cylinder 10.

Abstract: 887,727. Two-way transmission systems. GENERAL ELECTRIC CO. Ltd. Dec. 7, 1959 [Dec. 10, 1958], No. 39853/58. Class 40 (4). In a carrier telephone system, in which a carrier signal is amplitude-modulated by an information signal, e.g. speech, at a terminal station, the signal then being transmitted with both its sidebands, supervisory signals are transmitted by shifting the carrier selectively to one of a number of different frequencies, this method avoiding interruptions to subscriber's calls. Separate transmit 1 and receive 2 paths are connected in parallel between the input and output of the equipment. Transmitter.-Audio signals from the subscriber's line 3 pass through hybrid network 5, to a level adjusting pad and limiter either alone or in combination with a compressor unit 10 and thence through low-pass filter 11 to modulator 12. The modulated carrier derived from oscillator unit 13 and modulator 12 is amplified and passed via filter 15 and transformer 16 to the line 4. Oscillator unit 13 is composed of oscillators 31 and 32 operating at frequencies #c and #c - #s, e.g. 16 kc/s. and 15.850 kc/s. coupled by hybrid network 33 to modulator 12 ; oscillator 32 replacing oscillator 31 when relay set 28 responds to the calling loop. Receiver.-Modulated signals from line 4 pass via transformer 16, filter 17, level-adjusting pad 18 and amplifier 19 to hybrid network 20. After detection at 22 the audio speech signals pass via a level-adjusting pad 25 or a pad 27 and expandor unit 26, and hybrid network 5, to the line 3. A frequency discriminator network 29, includes a filter 34 sensitive only to a frequency fc-fs, this signal, after rectification and amplification, controlling a sensitive polarized relay in relay set 28 which repeats the dialled pulses. Frequency discriminator network 29 may comprise two frequency selective networks, one responsive to fc and the other to fc - fs, the two outputs being used to operate the sensitive relay. A frequency of #c +#s may be substituted for #c - #s.

IPC: H01B11/02
Filed: 1962-10-25
Abstract: 1,059,342. Distributing music &c. COMMUNICATIONS PATENTS Ltd. Oct. 18, 1963 [Oct. 25, 1962], No. 40403/62. Heading H4R. [Also in Division H1] In a wired broadcasting system for the distribution of audio-frequency signals in respect of sound programmes and high-frequency signals in respect of television signals, the distribution network comprises a cable in which each of a plurality of pairs of twisted together insulated conductors serves for the transmission of highfrequency signals in respect of a plurality of different television programmes, these highfrequency pairs are arranged in a compact symmetrical group about a centre core element, and the conductors of each pair of a further plurality of pairs of conductors which serve for the transmission of the audio-frequency signals are arranged within the circumscribing cylinder of this group. The system comprises a transmitting station 4, receiving stations 5 and a network comprising a multi-line cable 6. The transmitting station 4 includes A.F. amplifiers S1, S2, S3 for sound programmes and H.F. apparatus TV1 to TV6 for television programmes. Each receiving station 5 includes a combined television and sound receiver 9 and a selection switch 10. The cable 6 may comprise six twisted pairs of conductors 11 to 16, each pair being connected to a different high-frequency apparatus and a centre core made up of three twisted pairs of conductors 17 to 19, each such pair being connected to a different amplifier S1 S2, S3. Each pair is twisted to a different pitch. Similar but smaller gauge cables 20 are used as branch cables. Sound signals accompanying a television programme are transmitted over the same path as the corresponding high-frequency picture signals. Alternate ones of the highfrequency pairs of the network transmit carrier waves of the same frequency and adjacent highfrequency pairs transmit carrier waves of different frequency. Thus only two carrier frequencies are involved, with consequent simplification of transmission and receiving equipments. The carrier frequencies differ by an odd multiple of half the line frequency or an odd multiple of one-third the line frequency. In an alternative arrangement (Fig. 3, not shown), high-frequency pairs of the cable (preferably alternate H.F. pairs) have additional conductors constituting a twisted pair arranged in their interstices for transmission of A.F. signals. The centre core may then be a single twisted pair or a twisted group comprising three audio-frequency pairs or polythene string.
