Title: Improvements in or relating to multiplex transmission systems for television and like signals
IPC: H04J3/00
Filed: 1955-05-10
Abstract: 773,251. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 10, 1955 [May 10, 1954], No. 13517/55. Drawings to Specification. Class 40 (3). In a multiplex television transmission system two separate sets of signals relating to different pictures or to different aspects of the same picture are modulated on to individual pulse trains of similar repetition frequency N, equal to an odd multiple of half the line scanning repetition frequency, and the two modulated pulse trains are then fed to a combining device (leading to a common transmission path) via individual filter circuits one of which passes frequencies between 0 and ¢ N and the other of which passes frequencies between ¢ N and N. At the end of the transmission path the received signals are split into two groups by means of similar filter circuits and fed to individual demodulators to which are also supplied locally generated pulse trains of frequency N so that the original signals are recovered, the frequency and phase of the locally generated pulse trains being controlled by a reference signal comprising a " burst " of a sinusoidal wave of frequency equal to the pulse repetition frequency transmitted during the occurrence of the back porches of the line-scanning synchronizing pulses. The recovered signals are then supplied to the picture reproducing apparatus via filter circuits passing frequencies between 0 and N. With the arrangement described " cross-talk " between the two sets of signals is stated to be absent when, due to disturbances in the transmission path, the phase of the locally-generated pulse trains departs temporarily from that of the pulse trains employed at the transmitter. It is also stated that the individual pulse trains on which the television signals are modulated may have any phase relationship if the filter circuits employed at both transmitter and receiver have a sharp cut-off at frequency ¢ N. Failing this, a phase difference of 90 degrees is desirable.

Title: Improvements in apparatus for drawing sheets from a body of molten glass
IPC: C03B15/08
Filed: 1923-05-23
Abstract: 217,736. Pilkington Bros., Ltd., and Railton, D. May 23, 1923. Drawing.-In an apparatus for drawing sheet glass, the metal is conducted from a region below the surface of the molten mass through two channels to the two sides respectively of the line of draw, in order to secure an even temperature on both sides of the sheet at the drawing point. Apparatus for carrying out the process consists of a refractory structure, comprising outer walls 1 and a central partition 2, which is inserted in the mass 3 of molten glass, as shown. The sheet 5 is drawn from a line above a ridge 8 formed on the partition 2, and the metal that forms the sheet is drawn from a, region 6 below the surface of the molten mass and flows to the drawing point through the two channels 7 at the sides of the partition. The outer walls 1 may be continued upwards to form a drawing-chamber, and they may be integral with or separate from the partition 2. In the, latter case, the partition and the walls may be movable relatively to one another so that, by varying the width of the channels 7, any difference of temperature between the two streams of metal may be compensated.

Title: Improvements in or relating to braun tubes
IPC: H01J31/12
Filed: 1938-05-06
Abstract: 514,463. Cathode-ray tubes. SHEVLIN, J. T. (Hinderer, H.). May 6, 1938, No. 13641. [Class 39 (i)] In a Braun tube for the successive indication of a number of quantities a stream of electrons is deflected by a preliminary deflecting system successively into different pairs of a number of pairs of deflecting plates. The tube comprises an electron gun 3, producing two beams which pass through deflecting plates 4, 5 supplied with such a potential that the first beam passes successively through the deflecting measuring systems 9, 8, 7, 6, and then through the systems of the next row in the same order, while the second beam follows a similar path starting with the system 11. The plates of the measuring systems are supplied with potentials proportional to the quantities to be measured, or one pair of plates in each system may carry a time-base. So that, if desired, the traces produced by each measuring system may have the same zero point a steady potential may be applied to the measuring plates or to a conducting lattice 13 which separates and shields the different systems. The order in which the measuring systems are traversed may be changed by altering the potential on the systems 4, 5. If the potential applied to the plates 4, 5 is of the correct, stepped form no compensation is needed, but if any other variable potential is used the compensating systems 14, 15 are required to keep the effective zero position of the beam constant while it is passing through each measuring system. The corresponding plates of the systems 14, 15 are connected in parallel, and to the corresponding plates of the other systems 14, 15, and to them are applied potentials of opposite phase to those of the plates 4, 5. Alternatively a single common compensating system 16 may be used, or the system 16 may be used for adjusting the time-base or zero of the traces. The preliminary deflecting system and the compensating systems may be replaced by magnetic coils 24...29, the coils 26-29 being connected in the reverse direction to the coils 24, 25. One beam only may be used and this may be circularly deflected to pass through only certain of the measuring deflecting systems, or the deflecting systems may be mounted in a circle. Two beams may be used with only one row of measuring deflecting systems. Means for producing after-acceleration may be provided. When magnetic deflection and compensation is used, and to prevent eddy-current heating, the plates exposed to the field may be slotted and provided with an insulating support, or may be in the form of slotted metal deposits on an insulating body.
