Abstract: 1,252,950. Colour television. FERNSEH G.m.b.H. 1 Aug., 1969 [1 Aug., 1968; 30 Jan., 1969], No. 38728/69. Heading H4F. A colour television signal characteristic of a first standard system, e.g. a 525 line N.T.S.C. signal, is converted to a second standard system, e.g. a 625 line PAL signal, by splitting the incoming signal into luminance and chrominance components in a filter 1, Fig. 2, producing a new chrominance signal by frequency mixing in a modulator 5, the new signal having a subcarrier frequency which is lower than the original and is an integral multiple of the line frequency of the first system, converting the new chrominance signal to the synchronizing standard of the second system, e.g. using a scanned monochrome vidicon tube converter 9, changing the sub-carrier frequency of the converted chrominance signal to the desired sub-carrier frequency of the second system, and then combining the resulting chrominance signal with the luminance signal which has meanwhile been converted to the second system in a converter 10. In Fig. 2 the frequency mixing process to produce the new chrominance signal comprises producing in a frequency, divider and multiplier 7 a signal having a frequency <SP>9</SP>/ 7  times the signal colour sub-carrier frequency (3À6 Mc/s. for N.T.S.C.) and combining this with the original sub-carrier to produce a difference signal having a frequency <SP>2</SP>/ 7  times the original sub-carrier frequency. The 4À43 Mc/s. PAL subcarrier frequency is generated at 13 and is combined in a modulator 14 with the 65 TL multiple of this frequency from a multiplier 15. Band pass filters 16, 17 select one side band each from the resulting signal and an electronic switch 18 alternately supplies these to a modulator 19 where they combine with the converted chrominance signal. A filter 20 selects one of the side band products and combines it with the converted and transit time compensated luminance signal in an adder 21. The arrangement of Fig. 3 is modified by the addition in an adder 28 of a pilot signal to the new chrominance signal prior to conversion. In this case the frequency mixing produces a new colour sub-carrier frequency of 130 fH  ( fH  = half-line frequency) the pilot signal frequency being 260 fH . After conversion the pilot signal is brought, by means of a filter 33 and frequency divider 36, to the frequency of the converted chrominance signal and is used in demodulators 34, 35 to produce colour difference signals. The need for a separator standards converter for the luminance component is avoided in a modification in which the pilot signal is used as the sub-carrier for the luminance information. Various modifications of these basic circuits are disclosed.

Abstract: 1,256,938. Cigarette making machines. R. J. REYNOLDS TOBACCO CO. 12 May, 1969 [31 May, 1968], No. 23997/69. Heading A2C.  In a machine for forming continuous cigarette or filter rod in which an edge of a wrapping web is coated with adhesive and closed over the filler material by a folder block 24 mounted such that it can be flexed to vary the diameter of the finished rod, pneumatic means sensing the finished rod diameter controls flexure of the block in a manner to maintain a substantially constant rod diameter. A fluid amplifier 39 is controlled by the pressure difference in a pair of conduits 56, 60 which are connected to a pneumatic source 36 through restrictions 42, 48 and have restricted outlets to atmosphere. The outlet from conduit 56 is through openings 35 leading to an annular gap around the finished rod 34, and that from conduit 60 is through an adjustable reference restriction 52. Any variation in the diameter of the rod 34 alters the pressure difference in conduits 56, 60 to cause the amplifier 39 to effect a corrective adjustment by flexure of the block 34 through bellows 68, 70, a link 72 and lever 74. A rotary pneumatic motor acting on the block 24 through a screw mechanism may be used instead of the bellows and lever arrangement.

Abstract: 1,257,153. Transistor gating circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 13 Jan., 1970 [16 Jan., 1969], No. 1597/70. Heading H3T. In the circuit shown in Fig. 2 binary information from G appears inverted at U if a control signal at Y is positive, the latter signal being also applied to a second emitter of T 1  to ensure that when Y goes negative and turns off T 2 , then T 1  continues to conduct for a time (dependent upon its base capacitance to earth Cp) to discharge stored carriers from T 2  base. The capacitance Cp may be inherent or may be a capacitor, or both; and a third emitter input may be provided and connected to an X input so that Y and X can be together used for selection of the information source G. Since switch-on of T 2  would also be slowed by Cp, a transistor (T3, Fig. 3, not shown) may have its base-emitter path connected between R 1  and T 1 , and its collector connected through another resistor R 3  to the supply Vp, in order to compensate. The resistor (R3) may be connected alternatively (Fig. 5, not shown) in the emitter circuit (of T 3 ). Two transistors are connected in series in the base circuit of T 1  each receiving Y and X respectively at their bases (Fig. 4, not shown) in an embodiment which reduces power dissipation in the circuit when T 2  is off. The circuits may be integrated.
