Title: Improvements in or relating to television and the like systems
IPC: H04N5/067
Filed: 1933-02-15
Abstract: 415,118. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex, and BROWNE, C. O., 29, Monk's Drive, West Acton, London. Feb. 15, 1933, No. 4689. [Class 40 (iii).] In television systems in which the synchronizing signals become delayed or advanced in transmission as compared with the picture signals, means are provided for advancing or delaying the production of the synchronizing signals at the transmitter ; in this way the need for a long interval between successive line-scannings is avoided. Thus a line-synchronizing signal may be superimposed at the transmitter as a pulse a of sub-carrier frequency on the picture signals b, and framesynchronizing signals may be similarly superimposed. The synchronizing signals are generated by momentary illumination of a photo-electric cell at instants so timed that the line-synchronizing signals a are generated earlier than the intervals 1 which separate the line-scannings. The output valve 26 receives picture signals from valve 2, and sub-carrier oscillations modulated by line-synchronizing and frame-synchronizing impulses from valves 12, 21 respectively, these valves being fed with modulating signals through the circuits 3, 5, and with sub-carrier oscillations through the circuit 7. The acceptor circuit 18, 19 shunted across the output terminals of valve 12 byepasses the line frequency and its lower harmonics, and leaves only the sub-carrier impulses. The frame frequency, on the other hand, is not removed from the output of valve 21, but is retained for use at the receiver for blacking out the picture between frame. scannings. A rejector circuit 14 keeps the subcarrier away from the picture-current valve 2. At the receiver, Fig. 5, the demodulated signals are fed through a valve 30 to parallel circuits one of which includes an inductance 33 which resonates with its inherent capacity to the sub-carrier frequency, while the other includes a rejector circuit 37 tuned to the same frequency ; the tuned inductance 33 eliminates the sub-carrier from the grid circuit of the cathode-ray receiver, which is shunted across the impedance 34 and receives picture signals and frame-synchronizing signals only, the latter serving to black out the picture during intervals between frames. The rejector 37 applies sub-carrier impulses to rectifier 38 which controls synchronization. The sub-carrier impulses are delayed by circuit 14 at the transmitter (by the time taken to build up a given amplitude), by the tuned inductance 33 at the receiver and by the synchronizing unit (not shown) at the receiver ; the total delay is that which is compensated by generating the linefrequency impulses a, Fig. 2, in advance of the intervals 1 between the line-scannings. The circuit 34 may be replaced by a resistance shunted upon the inherent capacity of the oscillograph (Fig. 6, not shown).

Abstract: 768,472. Testing adhesives and viscosity. SUCKER GES., GEB. Feb. 22, 1955 (Feb. 27, 1954], No. 5340/55. Addition to 740,922. Class 106 (2). A method and apparatus for testing sizing liquid in accordance with the parent Specification is modified to test the viscosity of the liquid alternatively with its adhesiveness. As shown, the liquid is pumped by a reversible pump into a glass walled chamber 6 whence it flows via a variable constriction 13 and wets a pair of blocks 15, 16. The pressure of the liquid in the chamber 6, which is a measure of its viscosity, is indicated by means of a rubber bulb 7 and manometer 9. After a predetermined time interval the liquid flow is reversed and a solenoid 20 is energized to raise an armature 19 and hence raise the block 16 into contact with block 15. After a brief period of suction the pump is caused to run forward again and pressure will again build-up in the chamber 6 until the adhesion between blocks 15, 16 is broken down. The maximum value of this pressure is a measure of the adhesion. ' The cycle is then repeated. The pressures and temperature readings may be recorded on a paper strip fed by the solenoid impulsing device.
Patent GB-577171-A (GB)
Title: An improved manufacture of aromatic hydrocarbons
Filed: 1941-04-25
Abstract: <PICT:0577171/IV/1> A naphthenic oil is distilled so as to obtain a fraction which by dehydrogenation gives benzene, toluene or other desired aromatic hydrocarbon, and the fraction is then subjected to a heat treatment above 500 DEG  F. in the presence of hydrogen and a dehydrogenation catalyst.  The products, after fractionation to separate a fraction containing the benzene &c., is purified by extracting with a selective solvent for aromatic hydrocarbons, washing the extract with a highly paraffinic hydrocarbon having a boiling range different from that of the benzene &c., and recovering the latter from the washed aromatic extract.  In the Figure, which shows apparatus for the production of toluene, a naphthenic oil from tank 1 passes to a still 5 from which a fraction boiling at 150-270 DEG  F. is separated and passed to tank 7.  Hydrogen from supply tank 13 meets the oil from tank 7 and passes through a heater 17 to a catalytic chamber 19 containing a dehydrogenation catalyst such as alumina, in any form, together with an oxide or sulphide of a metal of Group IV, V, VI or VIII. Activated alumina, peptised alumina, silica-alumina gels, oxides and sulphides of molybdenum, chromium, tungsten, vanadium, cobalt and nickel are mentioned.  The cooled products pass to a separator 23; the hydrogen and other gases being recycled and the liquid products passed to a still 29.  The fraction containing toluene is collected in tank 33 and the higher and lower fractions are returned to the catalytic chamber or used in motor fuel.  The toluene fraction enters the bottom of a tower 37 in which it meets a downward flow of solvent such as liquid sulphur dioxide from a tank 38.  The raffinate passes from the top of the tower 37 to a still 41, the recovered solvent being returned to the tank 38 and hydrocarbons to the catalytic chamber.  The solution of toluene passes to a second tower 46 in which it is washed with a paraffin, from tank 47, either boiling below toluene, such as a pentane, or boiling above toluene, such as heavy naphtha or light kerosene. A second raffinate passes to a still 52 from which solvent, paraffin and non-aromatic hydrocarbon are removed.  The solution of toluene passes to a still 58 for the recovery of the toluene, solvent and paraffin.  Finally, the toluene is freed from olefines by an acid wash and distilled in a still 65.  In place of liquid sulphur dioxide, phenol, furfural, dichlorethylether, nitrobenzene, aniline, nitroaniline, chloraniline and chlorbenzene may be used.  Two or more catalytic chambers may be used to facilitate regeneration of the catalyst, and the latter may be suspended in the hydrocarbons.  In an example, a light naphtha fraction boiling between 160 DEG  and 270 DEG  F. is dehydrogenated and a product boiling between 200 DEG  and 250 DEG  F. thus obtained is extracted at -60 DEG  F. with liquid sulphur dioxide. After washing with isopentane, washing with acid and distilling pure toluene is recovered.  Specification 572,069 is referred to.
