Title: Process for the separation of conjugated diolefins
IPC: C07C7/08
Filed: 1966-12-29
Abstract: A process for the separation of a conjugated diolefin from a C 4 or C 5 hydrocarbon mixture containing said conjugated diolefin and higher acetylenes (including allenically unsaturated hydrocarbons) comprises subjecting the hydrocarbon mixture to extractive distillation with a solvent consisting essentially of an N-alkyl substituted aliphatic acid amide of the formula RCONR 1 R 2 , wherein R and R 1 are each a hydrogen atom or a C 1 -C 3 alkyl radical and R 2 is a C 1 -C 3 alkyl radical, recovering the conjugated diolefin as a distillate and the higher acetylenes as an extract in the solvent, and subjecting the extract to stripping so as to recover the solvent as bottoms liquid and the acetylenes as overhead fraction. If the hydrocarbon mixture also contains hydrocarbons less soluble than the conjugated diolefins such as paraffins and mono-olefins, then a two stage extractive distillation process may be used to recover the pure conjugated diolefin, a mixture of the conjugated diolefin and higher acetylenes being obtained as an extract in the first stage and the less soluble hydrocarbons removed as top distillate, the extract then being extractively distilled in accordance with the invention to obtain the pure conjugated diolefin as distillate in the second stage. Examples describe the recovery of butadiene 1,3 and isoprene from C 4 and C 5 feedstocks respectively. The amide solvent is preferably dimethyl formamide, diethyl formamide or dimethyl acetamide and may be used in admixture with 0-01 - 30% by wt. of a polymerization inhibitor e.g. tertiary butyl catechol, sulphur, sodium nitrite, furfural benzaldehyde and aromatic nitro compounds.

Title: Car coupler anti-creep mechanism
IPC: B61G3/10
Filed: 1967-02-28
Abstract: A fixed-jaw, e.g. Willison, railway vehicle coupler comprises an anti-creep element 9 which is pivoted at 23, 24 to the lock 6 itself pivotable about 15, 16 in the head, and which is gravity-biased at 22 so that when the coupler is coupled (Fig. 4) to a similar coupler, the element surface 51 engages the surface 28 of a look-thrower 8 and the element surface 41 is aligned and engageable with (but normally spaced from) a recess 34 in the rear wall 32 of the coupler to prevent rearward pivoting of the lock 6, the end 29 of the element 9 extending in the lockset condition (Fig. 7) into an opening 36 in the shank of the coupler. On coupling (starting from Fig. 3), the pad 46 of the lock-set piece 10 is engaged by the other coupler and as the piece 10 pivots about 49, a lug 47 on the piece 10 allows the element 9 to pivot to engage the recess 34. Uncoupling is effected by rotation. of the lockthrower 8 by its shaft 7, the thrower 8 initially disengaging the element end 29 downwards from the recess 34, and then engaging the lock surface 53 to rotate the lock, and lifting the piece 10 by means of a lug 54 until the lug 54 engages the rear surface 57 of the piece 10, so that the coupler is in the lock-set condition (Fig. 7), and uncoupling being completed by separating the couplers. The lock-set condition is cancelled by lifting a handle 61.

Title: Improvements in or relating to Wired Broadcasting Systems and Apparatus
IPC: H04N7/10
Filed: 1967-03-18
Abstract: In a wired broadcasting system for colour television the signal fed to the circuit comprises a modulated carrier brightness information signal, a suppressed carrier colour information signal and a pilot which has a frequency equal to a sub-multiple of the suppressed carrier of the colour information signal and which is used at the receiver to ensure that the reinserted carrier of the colour information signal is equal to the suppressed carrier frequency. The phase of the pilot signal is modulated in synchronism with the variations in phase of the colour component to provide synchronization for a PAL system signal. The Figure shows an embodiment for the reception and rebroadcast over a wire system of a " PAL " transmission. In this arrangement the brightness signal together with the colour signal on a suppressed carrier is applied to a modulator 19 where it modulates a carrier of about 5.4 Mc/s from oscillator 20, from which the signal is applied, via a vestigial sideband filter 22 and a gate 23 to the mixing circuit 24 for application to the lines 2 and 3. Also applied to gate 23 are signals derived from the incoming signal and applied over line 17 to enable colour burst signals at the frequency of the suppressed carrier of the colour components, i.e. 9.83 Mc/s., to pass to comparator 26 where they are compared with the output signal of a frequency tripler 27, which is fed with the locally generated pilot from oscillator 28, to provide an a.f.c. signal on line 29 which ensures that the pilot signal is maintained at one third the frequency of the suppressed colour signal carrier. The a.f.c. signal is applied as one input to a phase modulator 30, to the other input of which is applied colour recognition signals on line 18. The phase modulation by the colour recognition signals is such that the phase of the pilot is modulated by 60 degrees in synchronism with the phase modulation of 180 degrees of one of the colour components in the transmitted signal. At the receiver 6 the brightness and colour information signals are selected by a filter 34 and amplified by amplifier 35. The brightness component is demodulated by an envelope detector 36 and the colour components are applied, via filter 38, to synchronous detectors 40 and 41. The carrier for detector 40 is derived from the pilot signal by a wide bandpass filter 42, which passes all the sidebands due to the phase modulation applied at the transmitter, and a frequency tripler 43 so that the carrier is synchronously demodulated by a carrier whose phase reversals are synchronized with those of the colour component. The carrier for detector 41 is derived from the pilot by a narrow band pass filter 45 which passes phase stable pilot signal to tripler 46 from which a phase stable carrier is supplied to demodulate the phase stable colour component.

Title: Manufacture of electrically heated windows
IPC: H01Q1/12
Filed: 1970-03-06
Abstract: This invention involves a novel silk screen, a novel process of making it, and a novel use in the technology of heating flat bodies such as automobile and factory windows. The new screen is characterized by slits of differential width, depth, or both which permit the deposit of lines of differential section. This has a special significance when the lines are composed of electrical conductors of resistance type of which the resistivity of a part is determined by its section. The process involves a method of making the new type of silk screen which is extremely flexible and permits the construction of screens, the slits of which are differential only as to thickness. The invention has been achieved by a novel process which relies upon basic techniques already known to the silk screen art, such as the making of emulsions of proper conductivity for heating lines, the technique of preparing the emulsions, and the technique of dissolving those portions which must be removed to form the slits constituting the design. The invention also involves the novel windows which bear designs of differential resistivity producing different temperature in different parts. These advantages are particularly important in the automotive field but are equally so in factories where overhead windows can be kept clear to furnish light even during snowy weather. Other objects, novelties, and advantages of the invention will be apparent after the reading of this specification.
