In a system for distributing television or other carrier signals covering a wide frequency range from a central station 1 over a coaxial cable 3 including a number of repeaters 5 in cascade, local signals may be injected into the system from a studio 7S at a receiving station and are fed on a different carrier frequency through reversely arranged repeaters 29 to the central station where they are applied to a frequency-changing unit 21. Such local signals include synchronizing signals.

Title: An improved method and apparatus for inserting a mandrel in a tubular metal billet and for feeding the billet with the mandrel therein to a rolling mill
IPC: B21C3/16
Filed: 1969-09-04
Abstract: 1,248,834. Rolling mills. MANNESMANN A.G. 4 Sept., 1969 [6 Sept., 1968], No. 43738/69. Heading B3M. A mandrel 1 is rapidly fed by rollers 3 into a hot hollow billet 7 while the billet is moved slowly towards a continuous rolling mill 12. The speed of introduction of the mandrel is controlled so that the mandrel and billet are moving together, at the same speed as the first stand of the mill, as they enter the stand. The degree the mandrel extends from the leading end of the billet as the mandrel enters the mill is controlled according to the reduction to be made to the billet. The billet is intially fed from a lateral conveyer 6 on to rollers 10, the rollers then being raised until the billet is held in driving engagement between rollers 10 and 11. The rapid acceleration of the billet by the rollers 3 is helped by electromagnets 4 which pull the mandrel towards the rollers. Adjacent electromagnets are of reversed polarity, and a demagnetizing ring is provided, in order to prevent magnetization of the billet. The speed of the various rollers is controlled by a computer in response to signals from an infra-red position detector 5, a photo-cell 8, and displacement measuring devices 13 and 14. A lubricant spray device 15 is provided for the mandrel.

Reciprocating electrodes 25 form oblique welds 5 and horizontal welds 7, and electrodes 26 form lateral welds 4 which unite strips 12, 13 through hole 15 near the bag base. Individual bags are severed from the strips by a cutter 27.

Abstract: 1395721 Frequency synthesisers MARCONI CO Ltd 7 June 1972 [28 Sept 1971] 45024/71 Heading H3A A frequency synthesiser comprises a variable frequency oscillator 1, a frequency comparison arrangement 3, 5, 6 for deriving a first control signal representative of the difference between the synthesiser output frequency and a desired output frequency, a control arrangement 11, 16 responsive to the first control signal for controlling the oscillator 1, an arrangement 10 for determining whether the first control signal results from a drift of oscillator 1 frequency and a further arrangement 7-9 for generating a second control signal for oscillator 1 representative of the rate of the drift and for maintaining the second control signal until the drift rate changes. In operation, a pulse selector 6 receives a reference signal at 4 and a control signal at 17 to produce the desired beat frequency which is compared at subtractor 5 with the actual beat frequency produced by mixer 3 for deriving the first control signal which alters the contents of a reversible counter 16. When the oscillator 1 is set to the required frequency, the drift rate is detected and a reversible counter 8 is set to a count representative of this rate and a pulse generator 9 provides the second control signal to periodically correct oscillator 1. When the synthesiser is set to a new output frequency or a quantization error signal is produced at the output of subtracter 5, this is detected at 102, 101 respectively, and an inhibit signal is applied to gate 7 to prevent the drift control circuit being affected. The counter 16 and a digital to analog converter 11 may be replaced by a capacitive storage element having charge and discharge circuits in which case the generator 9 is replaced by a digital to analog converter. The detector 101 may include a monostable circuit.

Abstract: 1471877 Cathode-ray tube circuits RANK ORGANISATION Ltd 4 Sept 1974 [27 Sept 1973] 45273/73 Heading H4T [Also in Division G3] In an arrangement for scanning a continuously moving cinematographic film 4 (Fig. 1) by means of two vertically displaced (odd and even line) rasters on a flying spot cathode-ray tube 1 to generate corresponding signals in a photo-cell 6, variations in the spacing between the rasters is compensated by diverting a proportion of the scanning light, via a semireflecting means 3, into a secondary light path which includes a geometric pattern in the plane 7 of the secondary image, the pattern being so chosen that an electrical signal produced via a photo-cell 9 provides a measure of the raster spacing and this signal is employed to adjust the vertical deflection circuit to counteract any variation (caused by thermal and other factors) in such spacing. Fig. 2 shows the geometric pattern which is formed (on glass) by the heavy solid single vertical and two slant lines, the heavy dashed lines representing the limits of the two rasters. In operation, each scan of the beam across the lines produces two pulses the distance between which is a measure of the vertical position of such scan line and this distance is measured by the arrangement of Fig. 3 in respect of two corresponding lines, one from each raster, e.g. lines 25 and 338. As shown, the output of photo-cell 9 after amplification in 11 is separated into odd and even fields by line selectors 12, 13 and the distance between the pair of pulses due to the selected odd field line and the distance between the pair of pulses due to the selected even field line are measured in respective devices 14, 15 which involve either starting and stopping a ramp by the first and second pulses respectively of each pair or by counting high frequency pulses. The outputs of the devices 14, 15 are then stored in respective stores 16, 17, the difference between the contents of which, indicative of the raster spacing, is measured by a comparator 18. The comparator output is integrated and employed via the vertical deflection amplifier 19 to adjust the current in the vertical deflection coil 20 such that variation in the raster spacing is reduced to zero. A signal may be fed into the system to compensate for film shrinkage.

Abstract: A process for the production of allyl chloride comprising reacting propylene with chlorine at elevated temperature, fractionating the reactor effluent to remove unreacted propylene and by-product hydrogen chloride followed by distilling off light ends and then distilling allyl chloride as overhead product, is improved by treating the distillate from the fractionating step with aqueous scrubbing liquor to remove hydrogen chloride and leave wet propylene and then distilling from the aqueous liquor anhydrous hydrogen chloride, contacting wet propylene with anhydrous hydrogen chloride, condensing aqueous hydrochloric acid thus formed and separating anhydrous propylene. The wet propylene may be derived from the aqueous scrubbing liquor and may include fresh feedstock. The anhydrous propylene may be included in the feed to the reaction step.ALSO:Wet propylene is dried by contacting it with anhydrous hydrogen chloride, condensing aqueous hydrochloric acid thus formed and separating anhydrous propylene.
