Title: Television deflection system including afc circuit with regenerative phase detector
IPC: H03K4/60
Filed: 1967-10-02
Abstract: In a television receiver a deflection output stage has regenerative feedback via a transformer 32, the feedback winding 32b being coupled to the input of the output stage 30 via a capacitor 37 and under control of a switching transistor 29. The circuit shown is preferably employed to feed horizontal deflection coils 14 and is controlled by an astable multivibrator 27 which produces a substantially square wave output, the positive half cycle of which turns on transistor 29, which, in turn, turns off the output transistor 30 to initiate the flyback. After a quarter cycle of oscillation of components 14, 43, the base/collector path of transistor 30 becomes conductive, forming with diode 39 a damping circuit which provides a current path for the linearly declining current in deflection coils 14 during the first half of each sweep. Prior to the time at which the deflection current reaches zero, the multivibrator 27 turns off transistor 29 thus allowing the regenerative coupling via winding 32b to turn on transistor 30 so as to generate the second half of the sweep. Deflection amplitude stabilizing and protection arrangements.-The vertical deflection circuit (not shown) may be supplied from the junction of components 33, 34 decoupling resistor 33 being selected so that the effect of changes in intensity on the E.H.T. supply (provided by diode 41) are compensated by the change in deflection magnitude in such a way that the picture size remains unchanged. Resistor 33 also arranges transistor 30 to be cut off if it is brought out of saturation by high-voltage arcing. A clamping diode 44 and capacitor 45 protect transistor 30 against excessive collector voltages. The voltage across capacitor 45 may be supplied to one of the grids of the cathoderay tube. Automatic phase control.-Line synchronizing pulses are applied to the base of transistor 19 of a phase discriminator 18 and are compared with flyback pulses derived from winding 32b and fed to the emitter of transistor 20. Complementary transistors 19, 20 are regeneratively coupled so that they only become conductive during the simultaneous presence of both pulses and remain conductive until the voltage fed to the emitter of transistor 20 becomes reversed. The output of the phase detector 18 is arranged to control the frequency of the multivibrator 27 in such manner that the start of the retrace is arranged to occur three or four Ás. after the occurrence of each synchronizing pulse.

Title: Method and Apparatus for Making Glass.
IPC: C03B18/06
Filed: 1967-12-02
Abstract: In the manufacture of flat glass in ribbon form by delivery of molten glass 1 on to a bath 3 of molten metal, the glass 1 is initially confined and allowed to spread out on the bath 3 only to the extent defined by angularly disposed, splayed surfaces 11 of members 5 of a gas-permeable, porous refractory material, while a pressurized gas is blown out from-the surfaces 11 against the edges 10 of the glass, the molten glass then being permitted to flow laterally outwardly unhindered to the limit of its free flow to form a ribbon 11 of glass. As shown, each member 5 is formed with a cavity 6 parallel to the surface 11 and a conduit 7 is used to conduct gas under pressure to the cavity. The gas used is preferably non- oxidizing, e.g. nitrogen. The conduit 7 is surrounded by a conduit 9 which leads to a cooling box 8 secured along the top of member 5 and a conduit (91) removes the cooling water. The member 5 is preferably of graphite. In a modification, the surfaces 11 run parallel before splaying out. Reference has been directed by the Comptroller to Specification 1,112,071.

Title: Method for rounding pipe
IPC: B21D1/08
Filed: 1968-05-11
Abstract: A method for making an oval cast iron pipe circular in cross-section over at least a portion of its length is characterized in that whilst the pipe is within the temperature range 1000 to 1400 F. a transverse force is applied to a region of the pipe as the pipe is rotated in support means said force being sufficient to deflect the pipe in different regions of its surface in succession until the pipe cross-section conforms to a circular shape. The pipe is supported in rollers 2 one or both of which are driven. The transverse force is appled by a roller 3 actuated by an hydraulic cylinder 6 a stop 7 limiting the movement of the pivoted roller arm 4. The rollers 2, 3 extend over the whole length of the pipe and may comprise a single roller or a series of rollers arranged side by side. The single roller 3 may be replaced by two or more rollers arranged side by side and pressing upon circumferentially spaced portions of the pipe. In another embodiment (Fig. 2) the deflecting force is applied to the inner surface of the pipe by a cantilever roller mounted on a pivoted arm 14.

Title: Video amplifier
IPC: H04N9/72
Filed: 1969-08-20
Abstract: A video amplifier circuit for amplifying signals having repetitively occurring synchronizing intervals comprises a video input circuit for applying such a signal to the input electrode of an amplifier having stages 20, 24, via a capacitor 16, and a capacitor charging circuit which comprises a diode 40 which eliminates ripple and which is caused to conduct during the synchronizing intervals by a negative pulse from transformer 42, this pulse being applied via potentiometer 38 and resistor 36 to the capacitor 16 to charge it and at the same time to forward bias diode 18 which cuts off transistor 20 and thus disables the amplifier. The capacitor 16 is charged during these synchronizing intervals to a level which between these intervals suitably forward biases transistor 20 and allows operation of the amplifier. The value of this forward bias is determined by the charge on the capacitor, this being controlled by potentiometer 38. A circuit is given, Fig. 3 (not shown), of a colour television receiver employing such amplifiers. A further embodiment, Fig. 2 (not shown), employs feedback between the two stages 20, 24 of the amplifier.

Title: Method of controlling jumps to different programs in a computer working in real time
IPC: H04N1/403
Filed: 1970-06-16
Abstract: The invention refers to a method of controlling jumps to different programs in a computer which works in real time. A number of programs associated with different priority levels are performed sequentially within subsequent primary intervals determined by a clock register. The programs associated with the different priority levels have to be addressed in periodically recurrent intervals of different length. After having performed a program a sum value is formed by addition of the contents of the clock register and a number corresponding to the number of subsequent primary intervals within which the addressing of the program has to be omitted. Within each primary interval the actual value of the clock register in priority order is compared with the sum values associated with the respective programs. If the value of the clock register upon comparison is found to have passed a sum value that one of the programs is addressed with which said sum value is associated.

Title: Counting circuit for determining the incoming frequency or received channel in a high-frequency superhet receiver
IPC: H04B1/16
Filed: 1977-12-07
Abstract: The counting circuit is particularly useful in a high-frequency superhet receiver including IF filters, such as ceramic filters, available as completed units having definite, pre-aligned IF values, and is of the type in which the oscillations of an AM or FM local oscillator, the frequency of which differs from that of the received signal by the frequency of the IF stage of the receiver, are counted periodically by an electronic counter with each such count taking place within a predetermined gate time. In such a counting circuit, during the counting operation, a number of oscillations correspondng to a predetermined fixed number of oscillations occurring at the IF of the receiver is either subtracted from or added to the oscillations of the AM or FM oscillator so that the count of the counter indicates the incoming frequency or received channel. The gate time is determined by the pulse duration of periodically generated pulses and, in accordance with the invention, deviations of the actual IF of the IF stage relative to the predetermined fixed value of the IF taken into account during the counting operation, are compensated by shifting the leading edge, determining the beginning of the gate time, to vary the duration of the periodically generated pulses. Such shifting of the leading edge can be effected in an RC circuit including either a potentiometer, fixed value voltage dividers, or a plurality of potentiometers selected by selector switches.
