Title: Improvements in or relating to decoder circuit arrangements for colour television receivers
Inventor: FREEMAN KENNETH GEORGE
IPC: H04N9/465
Filed: 1965-04-15
Abstract: 1,076,735. Colour television. MULLARD Ltd. Feb. 8, 1966 [April 15, 1965], No. 16251/65. Heading H4F. PAL colour television signals, in which the subcarrier reference " burst " not only provides synchronizing information for the receiver reference oscillator but also alternates in phase about the - Q axis as illustrated in Figs. 1 (a) and 1 (b) for the purpose of signalling the line sequential phase reversal of the I modulation axis, are demodulated by an arrangement as shown in Fig. 2, comprising I and Q synchronous demodulators 3, 4 and a reference oscillator 1 which is established at the mean (- Q) phase of the alternating "bursts" applied through gate 2 and supplies a Q reference output to demodulator 4 and a I reference output to demodulator 3 via a switched inverter operating a line frequency, the arrangement being characterized by the provision of a second gate 7 which applies the output of demodulator during the " burst " to establish the line sequential operation of inverter 5 in the correct phase. In an alternative arrangement (not illustrated in detail) a third synchronous demodulator operating with the reference output from inverter 5 is used to provide the " burst " signal via gate 7 to the inverter. The signal via gate 7 is of the same polarity for successive " bursts " due to the line sequential phase inversion of the I reference signal, but changes in polarity should the phase of the line sequential operation of inverter 5 become incorrect. A polarity responsive device, such as a rectifier diode, is utilized to detect the signal polarity and apply a correction to the inverter. The inverter may comprise a diode switch controlled by a multivibrator driven by line frequency synchronizing pulses, the signal from gate 7, in the event of incorrect polarity, being applied to temporarily alter the multivibrator cycling time so as to reestablish operation in the correct phase. Reference is made to arrangements for use where the quadrature modulation axes are other than I and Q, e.g. R-Y, and B-Y. The invention may be applied to the demodulator described in Specification 1,005,290.

Title: A device for shaping transparent crystals for watches, clocks and other instruments
IPC: G04D3/06
Filed: 1933-06-12
Abstract: 400,555. Shaping watch &c. glasses. FUERY, G. T., 8, Newhall Street, Birming- ham.-(Mansson, M. ; 2, Arsenalsgatan, Stockholm.) June 12, 1933, No. 16706. [Class 100 (ii).] Watch and like glasses are made from sheet celluloid, synthetic resin, and like materials by a pressing operation. A cutting die 35, Fig. 3, with an inner polished parabolic surface 35b, Fig. 6, and an outer conical surface 35c, is mounted in proximity to an electrical heating- appliance 3 and receives the sheet of material 36 on its upper surface. The bezel or the watch case itself may serve as the die in some cases. An upper pressing die comprises a sheet of rubber or like material 17 fixed at its periphery to the casing 14 and adapted to be initially set to the concave or convex shape of the glass by raising or lowering the centre by means of a screw operated by the handwheel 21. A scale on the sleeve 22 assists the setting-operation. A hand-wheel 10 depresses the set die and its carrying-arm 9 by screwmechanism against the action of the spring 11 until the material is wholly or partly severed by the die 35. The shaped portion 35b of this die assists in maintaining the cut blank in the curved form imparted to it by the upper die. The heating-appliance has two circuits, one under the control of a press-button switch for initially heating-up the material and the other under the control of an ordinary throw-over switch for making up radiation losses, this circuit being used alone when the machine is in full running condition. A scale 24, with provision for setting at zero when the upper die touches the sheet, is used to determine the exact amount of rotation to be imparted to the hand wheel 10. The apparatus is used also to mount the glasses in the bezels of the watches. A die 37, similar to 35 in inverted position, is fixed on the pivoted arms 27 by depressing the screw 28. The case or bezel is slipped over one of a series of cushions 32, Fig. 4, which is then rotated into register with the die 37 and the glass placed on top of it. Depression of the die by the hand-wheel 10 then deforms the glass by depressing the edges on the cushion relatively to the centre. The bezel can then be raised by hand so as to fit over the glass. On raising the die again, the glass increases in diameter and grips the bezel firmly.

Title: Improvements in or relating to drying animal glue
IPC: C09H9/02
Filed: 1955-06-10
Abstract: Animal glue in the form of continuous sheet which is free from blisters and holes is obtained by forming a layer of aqueous glue liquor on a rotating internally-heated metal drum, and directing radiant heat on to the outer surface of the layer which, when a large proportion of the water has been evaporated, is scraped off the drum in the form of a sheet.  Heating steam at about 230 DEG  F. is supplied to drum 10 through ports in hollow shaft 11.  A pool of the aqueous liquor, containing about 40 per cent solids, is maintained in vessel 13; and this liquor is applied by roller 14 to the drum where it is formed into a continuous layer by compressed air discharged from pipe 15, and by baffle 16.  <PICT:0780623/III/1> <PICT:0780623/III/2> Blowers 18 direct a heavy stream of air against the layer on the ascending side of the drum.  The air and evaporated water are discharged through hood 19.  A battery of infra-red lamps 21 are mounted adjacent to the descending side of the drum; these keep the outer surface of the glue sheet at 170 DEG  F. and soft enough to allow the escape of small bubbles of vapour.  When the water-content of the sheet has been reduced to about 22 per cent, it is scraped off by doctor knife 22, which may be heated, while the opposite side of the sheet is cooled by a stream of cool air from perforated pipe 23.  The sheet is passed between brine-cooled calendar rolls 24 and 25; it adheres to roll 24 from which it is removed by knife 26.  The sheet is then conveyed to an air dryer within which it is reduced to its final moisture content. Specification 707,412 is referred to.
