Title: Improvements in or relating to television systems
Inventor: OVERTON BRYAN RICHARD
IPC: H04N9/45
Filed: 1954-11-18
Abstract: 789,673. Television. MULLARD RADIO VALVE CO., Ltd. Feb. 14, 1956 [Nov. 18, 1954], No. 33434/54. Class 40 (3). [Also in Group XL (c)] In a television system utilizing a main vision signal v, v<SP>1</SP>, such as a luminance signal, modulated on a main carrier V, a pair of quadraturemodulated signals c such as colour signals, on a sub-carrier C and a sound signal on a carrier S, there is transmitted a reference carrier signal R, the frequency difference between which and the sound carrier S is employed at a receiver to produce a phase-reference signal for the synchronous demodulation of the subcarrier. In one arrangement having frequencies selected for example as shown, the carriers C, Sand R are equally spaced. After demodulation at a frequency centred on the main carrier, the sound and reference carriers appear at 3.5 and 4.3 Mc/sec. respectively. These are then selected and applied to a square-law detector wherein a difference frequency of 0.8 Mc/sec. is produced and combined with the original 3.5 Mc/sec. to produce a lower side-band at 2.7 Mc/sec. corresponding to the frequency at which the sub-carrier appears and serving as the phase-reference signal. The signals are produced at the transmitter starting with signals of 2.7 Mc/sec. and 3.5 Mc/sec. The 2.7 Mc/sec. signal which provides the subcarrier is divided down and locked to the mains supply frequency. The 2.7 Mc/sec. and 3.5 Mc/sec. signals are then fed to a square-low mixer to obtain 4.3 Me/sec. and this, together with the 3.5 Mc/sec. are combined with a 4.5 Me/sec. carrier to produce the sound and reference carriers at 41.5 Mc/sec. and 40.7 Mc/sec. respectively. In an alternative arrangement, the reference frequency carrier R is located at 40.6 Mc/sec. so that the difference between carriers S and R equals 0.9 Mc/sec. which may be multiplied by 3 to obtain directly the phase-reference signal at the 2.7 Mc/sec. of the sub-carrier. It is stated that the difference between the reference and sound carriers may be made any integral multiple or sub-multiple of, or equal to, the sub-carrier frequency. In another arrangement, Fig. 2 (not shown), the reference carrier R is located between the sound carrier and the sub-carrier at a frequency of 41.9 Mc/sec. In yet another arrangement, Fig. 3 (not shown), the subcarrier is located outside the band of the main vision signal between the reference and sound carriers. The invention is stated to be applicable to systems where the sub-carrier is subjected to periodic 90 degree phase shifts to reduce cross-talk. The reference carrier is subjected to similar phase shifts so that the phase reference signal derived at the receiver undergoes corresponding changes. Where the sub-carrier is locked to the mains frequency, the effects of variations in the main frequency may be compensated by applying corresponding variations to the reference carrier so to maintain the desired multiple or sub-multiple relationship between the carriers concerned.

Abstract: 986,430. Controlled semi-conductor rectifier switching circuits. LICENTIA PATENTVERWALTUNGS-G.m.b.H. Sept. 20, 1961 [Sept. 28, 1960], No. 33671/61. Heading H3T. In a circuit comprising two controlled PNPN or NPNP semi-conductor rectifiers connected in series so that when one of the rectifiers is ignited the other consecutively ignites an R.C.- circuit chain is connected in parallel with the two rectifiers and a resistor is connected between the connecting point of the two rectifiers and the mid-point of the R.C.-circuit chain such that the voltage drop across the resistor when one of the rectifiers conducts causes a current to flow through a diode, Zener diode, capacitor or resistor connected between the mid-point of the R.C.-chain and the control electrode of the second rectifier and hence the latter rectifier to consecutively ignite. As shown in Fig. 2, two PNPN or NPNP controlled semiconductor rectifiers 1, 1<SP>1</SP> biased by resistors 2, 2<SP>1</SP>, are connected in series, and if rectifier 1 is caused to ignite by a control voltage applied to terminals 5, 6 the rising anode current of the ignited rectifier results in a potential drop across resistor 8 connected between the mid-point of R.C.-circuit chain 4, 4<SP>1</SP> and 3, 3<SP>1</SP> in parallel with the two rectifiers and the connecting point of the rectifiers. The resulting current flow through diode 7 to the control electrode of rectifier 1<SP>1</SP> causes the latter to ignite. Any mains over-voltages which occur do not cause rectifier 1<SP>1</SP> to ignite before rectifier 1 does because of the symmetrical arrangement of the resistors 2, 2<SP>1</SP> and the R.C.-circuit chain, there being no resulting voltage drop across resistor 8 and hence no current flow through diode 7. The diode 7 may be replaced by a Zener diode, capacitor or resistor.

Abstract: 997,864. Spray burners. PEABODY Ltd. July 25, 1963 [Sept. 5, 1962], No. 33987/62. Heading F4T. An oil burner wherein oil is fed through a supply tube 2 to a spray nozzle 1 has means to shut-off and clean the spray nozzle orifice 4. Within the supply tube 2 is an inner sleeve 5 within which is slidably arranged a valve rod 6 which is connected at one end to a valve closure member 7 and at the other end to a spring-loaded piston 8 in a cylinder 9. The valve closure member 7 is slidable in a cylindrical guide member 10 at the forward end of the tube 2 and has at its forward end a cleaning plug 11 adapted to mate with the nozzle orifice 4, and its rear end 12 seats against the forward end 13 of the inner sleeve 5. A spring 16 acting on the piston 8 biases the plug 11 into the nozzle orifice 4. In this position the oil flows between the oil supply tube 2 and the inner sleeve 5 and through passages 27 to the nozzle 4 and returns through the open forward end 13 of sleeve 5 to an oil outlet tube 15 in the burner housing. To start the burner compressed air forces the piston 8 against its spring 16, thus withdrawing the cleaning plug 11 from the orifice 4. The circulating oil path is blocked by the rear end 12 of the closure member 7 seating against the forward end 13 of the inner sleeve 5. In a modification, Fig. 2 (not shown), an annular passage is formed between the supply tube and an outer cylindrical casing through which steam or compressed air is supplied to the interior of an atomizer via transverse holes in the supply tube walls. In a further modification, Fig. 3 (not shown), part of the oil passes to the spray nozzle orifice and the rest is returned through the burner assembly. The oil is supplied to a central chamber through an annular passage and then divides, part passing to the spray nozzle orifice and the remainder passing to an oil return pipe.
