Title: Highway radio communication system
IPC: G08G1/0967
Filed: 1972-03-30
Abstract: 1342210 Radio signalling PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 30 March 1972 [2 April 1971] 15021/72 Heading H4L In a system for transmitting messages to vehicles travelling along a highway, the transmitter is provided with a directional aerial system which is automatically switchable to provide a coded pulse pattern to switch on a vehicle's receiver as it is travelling in one direction and a complementary pulse pattern for rendering the receiver of a vehicle travelling in the opposite direction temporarily insensitive to the pulse pattern and is also switchable to operate in the inverse manner. The transmitter, Fig. 2, includes a F.M. transmitter 6, receiving message signals from a source 7 and the aerial system comprises vertical aerials 4, 5 spaced by a quarter wavelength. A high-frequency oscillator 10 is arranged so that in position 4 of switches 8, 9 it is connected directly to aerial 4 and through a 90 degree phase-shifter 11 to aerial 5 and in position 3 these connections are reversed. By this means the transmitted signal is increased in one direction and is at a minimum in the other and a controller 12 sets the switch positions 3, 4, in a sequence determined by a pattern generator 13. This causes the code pattern to be transmitted after which the switches move to position 2 followed by position 1 and the message is transmitted. When a message is to be transmitted to a vehicle travelling in the opposite direction the code pattern is inverted. The receiver, Fig. 4 (not shown) includes conventional R.F., mixer, I.F., discriminator and A.F. stages, a muting switch being included in the A.F. stage. The I.F. stage also feeds a carrier detector supplying a pattern recognition stage, Fig. 5. When a pulse is applied to the input 22 it sets a monostable 25 via a normally conducting AND gate 24 to activate AND gate 26. The second pulse is therefore passed by gate 26 if it falls within the flyback period of monostable 25. If a pulse is passed it sets a bi-stable 27 to supply a signal at 23 to close the muting switch. When the monostable 25 resets it activates a timing circuit 28 which resets bi-stable 27 after completion of the message signal and blocks the AND gate 24 for a predetermined period. If the complementary pulse pattern is received the bi-stable 27 is not set and the AND gate 24 is blocked for a period so that the receiver is not responsive to the code pattern for that period. The period for which the receiver is made insensitive may be made dependent on the speed of the vehicle by measuring the difference in amplitude of the pulses in successive pulse patterns and adjusting the timing accordingly. The timing on output 29 of the timing circuit may be controlled by the duration of the message if this is not fixed. As an alternative to frequency-modulation the message signal may be transmitted as a PSK delta modulation signal.

Title: Process of steam-cracked naphtha light end products

Filed: 1959-05-04
Abstract: <PICT:0851437/IV(b)/1> In recovering C2-C5 hydrocarbons from the gaseous product of steam cracking naphtha containing some higher boiling constituents and from which higher boiling hydrocarbons have been separated in a quenching zone, the gas is cooled to condense C4+ hydrocarbons and water, separated in a separating zone into uncondensed gas, condensed hydrocarbon and water, the uncondensed gas from the separating zone is passed to a vapour compression zone, and thus further condensed hydrocarbons are passed to a fractionation zone the C5- overhead from which is passed with the gas from the quenching to be condensed and separated.  The effleuent from the cracking coil 3 is mixed with quench oil and passed to quench tower 7 where it is contacted in countercurrent with more quench oil.  Part of the circulating quench oil is bled off by line 15, fresh being added by line 9, while some oil is taken off by line 17 for use as a sponge oil in removing heavier hydrocarbons from a C2 cut and the fat oil is returned by line 18.  The overhead from tower 7 is cooled in cooler 21 and separated in separator 22, water being removed, some condensed hydrocarbon being returned by line 19 to the quench tower the remainder being fed to the top of fractionator 26 to separate C6+ as bottoms and C5- overhead, the latter being passed to cooler 21 and separator 22.  Gases from the separator are compressed and cooled and liquid formed separated in knock-out drum 34 and passed to fractionator 26.  Gases are further compressed and cooled and the gases and liquids obtained separately caustic treated at 48 and passed together to absorber 50 where they are contacted with an oil boiling in the range 80 DEG -200 DEG F. to absorb C3 and higher boiling hydrocarbons which are then recovered in debutaniser 58 while the C2 fraction is passed to absorber 54 where it is contacted with a sponge oil from the circulating quench oil from tower 7.

Abstract: 813,059. Valve accessories. SULZER FRERES S.A. May 17, 1956 [May 25, 1955], No. 15454/56. Class 135. The seating 4 for a single-beat lift valve is pressed against a packing ring 7 in the housing 1 by the pressure of the controlled fluid, e.g. steam at high temperature and pressure, and by the movable closure member, and is retained in position by one or more, preferably three, retaining devices disposed in bores 15 which are transverse, or have a substantial transverse component, relative to the axis of the valve rod which carries the closure member. The retaining devices are adjustable from outside the housing 1 and engage grooves 21 in oblique surfaces 20 corresponding in number to the number of retaining devices. As shown, a retaining device consists of a spindle 16 having screw-threaded engagement with a slide 18 formed with a nose 19 to engage a groove 21 in the seating 4. The spindle passes through a bored plug 23 and carries a flange 22 behind which a packing ring 24 is situated. The retaining devices may be arranged, as shown, to be subject to the pressure on the high-pressure side of the valve seating so that that pressure acts on the flange 22 to improve the sealing afforded by the packing 24. Alternatively, the retaining devices may engage the seating at a point below the packing ring 7 in which case they are not subject to the high pressure. In a further modification, the spindle 16 is replaced by a member with an internal screw-thread engaging an externally-threaded slide formed with the nose 19.

Abstract: Polymers and interpolymers of ethylene are manufactured by subjecting the monomer or monomers to an elevated temperature, preferably between 40 DEG  C. and 400 DEG  C. and an elevated pressure, preferably between 400 and 1000 atmospheres, in the presence of a tertiary alkyl percarboxylate.  Examples of these catalysts are tertiary butyl perbenzoate, tertiary butyl pertrimethylacetate and the tertiary butyl esters of pertoluic, perphthalic and per-alpha, alpha-dimethylalkanoic acids containing up to twenty carbon atoms. The polymerization may be carried out in bulk or in an inert liquid medium such as water, an organic solvent such as benzene, cyclohexane, iso-octane and tertiary butyl alcohol, or a mixture of water and a solvent.  The process is preferably continuous and effected in the absence of gaseous oxygen.  Compounds which may be interpolymerized with ethylene are vinyl chloride and fluoride, vinyl acetate, tetrafluoroethylene, methyl methacrylate, styrene, vinylidene chloride, vinyl succinimide, vinyl phthalimide, dimethyl fumarate or maleate and carbon monoxide.  1,3-Dioxolane is mentioned as a molecular control agent.  Pigments, dyes, fillers, antioxidants and plasticizers may be added to the products which are useful as fibres, films, coatings and electrical insulating material.
