Title: Circuit arrangement for field recognition in television systems
Inventor: BALDWIN JOHN LEWIS EDWIN
IPC: H04N5/08
Filed: 1964-01-31
Abstract: 1,044,873. Television. RANK-BUSH MURPHY Ltd. Jan. 29, 1965 [Jan. 31, 1964], No. 4186/64. Heading H4F. The invention relates to a circuit arrangement for field recognition in television systems employing odd-line interlaced scanning, i.e. a circuit arrangement which only produces an output signal when the field synchronizing signal corresponding to a particular one of two kinds of field (odd- or even-line field) is present. As shown, Fig. 1, television synchronizing signals (waveform A, Fig. 3, shows the commencement of field synchronizing signals of an EVEN and ODD field) received at terminal 1 are applied firstly to a field pulse generator 2 where they control the production of pulses corresponding with each field synchronizing signal (waveform 3B), and secondly to a line pulse generator 3 where they control the production of line-frequency rectangular pulse signals (waveform 3C) with mark-space ratio slightly receding 1:1. The field pulses are then applied to a gate circuit 4 in which they are controlled by the line pulses from generator 3 so that only alternate field pulses pass to an output terminal 5 (waveform 3D), i.e. the oddline field pulses are suppressed and the even-line field pulses are passed to the output terminal. In a further embodiment, Fig. 2, not shown, the line pulse generator in addition to generating the line pulses which in this embodiment are applied to a gate 7 (waveform 3C) also generates line pulses in opposite polarity (waveform 3E). which are applied, together with the field pulses (waveform 3B), to a second gate 4 so that the even-line field pulses are suppressed and the odd-line field pulses (waveform 3F) passed to an output terminal. This Specification includes detailed descriptions of circuit arrangements suitable for performing the functions of the field pulse generator (Fig. 4, not shown), and the line pulse generator and two gates (Fig. 6, not shown).
Patent GB-433052-A (GB)
Title: Improvements in or relating to the liquid treatment of yarns
IPC: D06B5/16
Filed: 1934-02-08
Abstract: Uniform liquid treatment of yarn on a bobbin is effected by surrounding the bobbin with a casing and forcing treating liquor through the bobbin into the casing which is maintained full of liquor under pressure during the operation by ensuring a slow rate of escape of the liquor.  The treating liquor may be a washing, bleaching or dyeing agent or a saponifying liquid for cellulose acetate or other cellulose ester yarns, and the yarn may be artificial continuous filament yarn and may be wound in cake or other package form.  The hollow yarn package 35 on a bobbin 16, Fig. 2, is placed on a hollow perforated spindle 7 and the upper flange 19 of the bobbin is clamped against an upper flange 18 on the spindle 7 by a nut 15 on a screw-threaded part of the spindle 7 engaging in fluid-tight manner the lower flange of the bobbin 16.  A casing 14 is held in position around the bobbin 16 by a clamping nut 11 on the screwed part of the spindle 7.  Fluid is supplied to the interior of the spindle 7 from a feed tank 30, Fig. 1, and passes out through the perforations 10 in the spindle 7 when the spindle assembly is rotated by a driving wheel 8 near its upper end, under the action of centrifugal force.  When the casing becomes full, the liquid in it reaches considerable pressure by reason of the slow rate of escape of liquor from the casing through three small perforations 21, liquor being supplied to make up for the flow from the casing.  A guard 27 surrounding the upper end 26 of the spindle 7 and a guard casing 23 surrounding the spindle assembly drain liquor into a tank 25 from which it is returned by a <PICT:0433052/IV/1> <PICT:0433052/IV/2> pump 33 to the feed tank 30.  The bobbin 16 is made of steel with a barrel comprising a number of bars of triangular cross-section with spaces between through which the treating liquid is thrown. A cylinder of gauze 38 may be placed between these bars and the yarn 35.  A similar cylinder may be placed inside the perforated or slotted spindle 7 to distribute more evenly the treating liquor.  The boring of the spindle 7 is tapered to fling downwards liquid entering at the top end 26 of the spindle.
