Title: Improvements in colour television transmitters
Inventor: ROE GRAHAM DUDLEY
IPC: H04N11/14
Filed: 1966-03-04
Abstract: 1,125,851. Colour television. BRITISH BROADCASTING CORP. 2 March, 1967 [4 March, 1966], No. 9651/66. Heading H4F. In a colour television system in which the signals transmitted comprise an information sub-carrier and a phase reference sub-carrier, the information sub-carrier being phase and amplitude modulated in accordance with the hue and a function of the saturation of the colour being transmitted, to reduce hue errors at low saturation produced during demodulation, a phase-modulated pedestal sub-carrier signal of fixed amplitude with the same instantaneous phase as the information sub-carrier is superimposed on the information sub-carrier. The reference sub-carrier may be amplitude modulated in accordance with a function of the saturation of the colour and transmitted simultaneously or line-sequentially with the information sub-carrier, e.g. as in the N.I.R. system, in which case a pedestal sub-carrier signal is superimposed thereon as well as on the information sub-carrier. In the latter system the information sub-carrier is of the form E c =(k+#C) cos (wt+#) and the reference sub-carrier is of the form Ec<SP>1</SP>=(k+#C) cos (wt+#), where C is the colour saturation, k is the fixed amplitude of the pedestal sub-carrier signal, # is a constant phase angle and # is the phase angle indicating phase modulation. In a transmitter for this N.I.R. system, a sub-carrier signal of the form K cos wt applied to terminal 10 is modulated in phase quadrature by colour signals E 1  and E Q  as shown to produce the signal C cos (wt+#). This signal is limited 15 to produce a constant amplitude signal K cos (wt+#) which is applied to a switch 17 together with a reference subcarrier K cos (wt+#), and these signals are applied alternately at line frequency to an amplitude modulator 25 via a blanker 18. An envelope detector 21 provides a signal C from signal C cos (wt+ #) which is applied to a non- linear amplifier 22 to derive #C. A pedestal forming signal k is supplied by potentiometer 23 and #C is superimposed thereon by means of a synchronous clamp 24 operated by the blanking pulses. The output of the clamp is k+#C which is used to modulate the output of the blanker 18 in modulator 25.

Filed: 1941-07-29
Abstract: 546,583. Discharge apparatus. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). July 29, 1941, No. 9655. Drawings to Specification. [Class 39 (i)] Silver electrodes, in a discharge tube containing an active layer of alkaline oxide, are coated with a very thin layer (0.01 micron or less) of an oxide of beryllium, magnesium, aluminium, zirconium, thorium or silicon, whereby the formation of active layers on these electrodes is avoided. The active layer may be photo- or secondary-emissive, for example caesium-silveroxide, such as are employed in photo-cells, iconoscopes, multiplier tubes and picture transformers. Usually the electrodes are coatings on the envelope, to form focusing or screening members. The thin layer may be applied by volatilization from a heated tungsten spiral or by heating a layer of ethyl orthosilicate ester sprayed or smeared on the electrode, which when heated to 100‹ C. will decompose leaving a thin layer of silicon dioxide.

Filed: 1966-03-04
Abstract: 1,137,894. Automatic temperature control systems. SUNBEAM CORP. March 4, 1966 [Oct.6, 1965], No.9692/66. Heading G3R. A temperature control circuit admitting only complete half cycles of power to a heater 14 comprises in direct heat conducting relation to the heater a NTC thermistor 26 in series with an adjustable resistor 24 and capacitor 20 forming a phase shifting circuit. The voltage at junction 28 fires through a diode 34 a thyristor 16 when this voltage exceeds the threshold value. A second thermistor 18 stabilizes the thyristor 6 firing point with rise in temperature. A diode 30 shunts the control circuit on negative half cycles. A resistor 36 compensates for overshoot by providing a standing current drain through thermistor 26. An additional thermistor (64 Fig. 4, not shown) connected in series with diode 34 and in loose thermal relation with the heater may also compensate against overshoot when the circuit is initially energized. Other circuit configurations are described in the Specification. The circuit may be applied to the control of an electric iron or a liquid bath. An R. F. filter 62 may be connected across the input terminals to by-pass transients to prevent spurious operation of the thyristor.

Patent HK-125897-A (HK)
Title: Transmission network and filter therefor
Inventor: BROWN PAUL ANTHONY
IPC: H04B3/54
Filed: 1997-06-26
Abstract: A power transmission network (40) is disclosed which includes input means (52) for the input of telecommunication signals having carrier frequencies greater than 1MHz onto the network (40), and a means for removing similar speech and/or data signals from the network. Preferably a network conditioning element (52) is used which includes a low pass filter portion for filtering out a low frequency high amplitude mains power signal, and a coupling element for input and/or removal of telecommunication signals from the network. In this way both speech and data signals can be transmitted at carrier frequencies of greater than 1MHz along a standard electricity distribution and/or transmission network which when conditioned provides a larger available spectrum per unit length of network and greater transmission capacity than previously known. The quiescent noise level of the conditioned network is also much reduced thus permitting lower signal injection levels for a given signal-to-noise ratio and a consequential reduction in spurious radiation from the network. <IMAGE>
Patent HK-139196-A (HK)
Title: Data communications network
Inventor: KIRBY LEWIS GEORGE
IPC: H04L12/56
Filed: 1996-07-25
Abstract: A network is arranged to generate circuits between source node (NS) and destination nodes (ND) by means of datagrams which are guided at each node over a path (D) which minimises delay in establishing the circuit. Certain sub-destination nodes (NB and NC) are designated as intermediate circuit nodes by the datagram and accordingly a circuit (C) is established. Each circuit node is determined by the preceding circuit node in such a manner as to minimise the hop count to the destination node (ND). To this end, each node incorporates in its memory (M) a first list (LIST 1) showing the link with the best hop count to each possible destination node and also incorporates a list (LIST 2) of its links with the best transmission delay to the destination node. These lists are updated dynamically by means of routing information packets which are exchanged between neighbouring nodes. However, best hop count and best delay information is not transmitted over those links (L) which are themselves the subject of that information. In this manner "ping-pong" type looping is avoided.
