Title: Arrangement for suppressing colour flicker
IPC: H04N11/08
Filed: 1964-08-28
Abstract: 1,082,151. Colour television. HAZELTINEAGA LABORATORIUM G.m.b.H. Aug. 28, 1964 [Oct. 5, 1963], No. 35305/64. Heading H4F. To suppress the colour flicker in a television receiver adapted for receiving a colour subcarrier in which the colour sequence is periodically changed, the chrominance or colour difference signal components having frequencies in the vicinity of odd multiples of half the colour sequence changing frequency are suppressed and/or the chrominance signal components having frequencies in the vicinity of even multiples of half the changing frequency are emphasized. A change in colour sequence may be represented as a change in polarity of the chrominance signal component Q o  and if a phase error occurs in transmission, the sub-carrier F appears at the receiver in the following form: and by means of synchronous detection in the receiver there is obtained: in which the components # Q 0  sin α and Œ I 0  sin a of I and Q change polarity in synchronism with the colour sequence and cause colour flicker. The Specification states that it can be shown by means of Fourier analysis that the alternating components are grouped about odd multiples of one half of the colour sequence changing frequency, i.e. in the spaces between the frequency groupings of the other components. Since the sequence can only be changed in the synchronizing intervals the changing frequency is related to the line or the field frequency. A high degree of suppression may be obtained by a suppression of one-half the changing frequency and/or the third multiple thereof by means of frequency traps. The even multiples of half the changing frequency may be emphasized by means of filters. Instead of using traps or filters a quarter-wave transmission line tuned to one-half the changing frequency and terminated at one end by its surge impedance and being short-circuited or open-circuited at the other end may be used. The terminating impedance may serve as the cathode or anode load circuit of an amplifying stage.

Abstract: 1,165,507. Control of D.C. motors. H. KOHLER, and H. MAY. 29 July, 1968 [28 July, 1967], No. 36136/68. Heading H2J. A transistorized braking circuit for a permanent field direct current electric motor M comprises two transistors T 1 , T 2  for effecting braking in the two directions of rotation of motor M respectively, each transistor T 1 , T 2  having its collector emitter path connected between the motor M terminals, each transistor further having its base connected to a point between a diode D 1 , D 4  of a first bend voltage and a resistor R 1 , R 2  in a lead which is directly connected at at least one end to one 2 of battery terminals 1, 2, for supplying motor M, battery terminal 2 being connected to that motor terminal to which the emitter electrodes are connected or to which the emitter electrode of one of the transistors is connected via two diodes D 2 , D 3  which have a bend voltage higher than the first bend voltage. By " bend voltage " is meant the voltage where the knee in the characteristic of a diode occurs. Diodes D 1 , D 4  are germanium and diodes D 2 , D 3  are silicon. During running in one direction as shown in Fig. 1, when the load current is from terminal 1, through motor M and diode D 2  to terminal 2, due to the voltage drops of unequal value across D 2  and D 4 , transistor T 2  receives such a bias between the base and the emitter that it is blocked. No current flows through transistor T 1  since it is poled in the blocking direction for the polarity shown. After the supply voltage has been switched off, due to elimination of the blocking voltage of D 2  and D 4  and the base current flowing through R 2 , transistor T 2  becomes conductive and short circuits the motor through its collector-emitter path to effect the braking. Operation in the reverse direction is similar except that transistor T 1  now short-circuits the motor. The diodes may be replaced by transistors operating as diodes. In a modification, Fig. 5 (not shown), both transistors are PNP or NPN and two extra diodes are used.

A thin film element receives a driving pulse from a thin film driving element by means of a low inductance loop which couples the elements. In the thin film memory described the storage areas are defined in thin magnetic films 22 by digit conductors 25, sense conductors 26 and word conductors 24. Each word conductor 24 is connected to the aluminium substrate 21 at each of its ends and is also coupled to a driving element constituted by an area of a second film 23. Each driving element is coupled to three further conductors; a bias conductor 29 which is coupled to all driving elements of the matrix, a plane select conductor 30 coupled to each driving element of a plane and a word position conductor 31 which is coupled to one element of each plane. The bias conductor 29 biases each driving element well into a hard direction so that currents in both conductors 30 and 31 are required to switch the element and thus drive the elements of the appropriate word on film 22 to a position within a few degrees of the hard direction. The elements are then read out on sense conductors 26 or written into by currents in the digit conductors 25. The conducting substrates 21 may be replaced by insulating boards if return conductors are provided for the word conductors 24. The planes of the three-dimensional matrix may be arranged parallel to each other with the conductors extending, with their insulating layers 13, 14, 15, 16, 17 and 18, in serpentine manner from plane to plane. The present driving method may also be applied to a shift register or to logical circuits. To produce adequate drive field the film 23 may have twice the thickness of film 22.
