Patent GB-603099-A (GB)
Title: Preparation of vinyl chloride
IPC: C07C21/06
Filed: 1945-06-14
Abstract: Vinyl chloride is prepared by cracking saturated hydrocarbons at 1200-1600 DEG  C. using a contact time not exceeding 15 secs., separating a fraction containing ethylene and acetylene and treating it with hydrogen chloride produced in a later stage of the process, either at 50-200 DEG  C. in the absence of a catalyst or at 50-180 DEG  C. in the presence of a mercuric chloride catalyst or 30-100 DEG C. in the presence of a halide of antimony or bismuth in the liquid state, selectively to convert the acetylene to vinyl chloride, separating this from the ethylene, reacting the ethylene with chlorine to obtain ethylene dichloride, converting this by pyrolysis to vinyl chloride and hydrogen chloride, separating the latter, and using it in the hydrochlorinating step.  The initial hydrocarbons may be gases or liquids and particularly gaseous paraffins of at least two carbon atoms such as propane although various petroleum fractions are suitable.  Inert gases or steam may be added.  Regenerative type or pebble furnaces may be used for cracking to give ethylene and acetylene in equimolar amounts which are separated, as by fractionation, from other products. After hydrochlorination of the acetylene, residual ethylene is treated with sufficient chlorine in liquid or gaseous phase and in the presence of an alkaline earth halide such as calcium chloride, at about 20-150 DEG  C. and atmospheric pressure or above, e.g. 2-10 atmos., to give ethylene dichloride.  This is heated in a packed tube to, for example, 400-800 DEG  C., and the products separated into vinyl chloride and hydrogen chloride for use in the hydrochlorination.  The Specification as open to inspection under Sect. 91 comprises the preparation of other vinyl halides, e.g. vinyl bromide.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to Solid State Modulators
IPC: H03C1/52
Filed: 1967-04-05
Abstract: 1,156,330. Balanced modulators. CIT-COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 5 April, 1967 [12 April, 1966; 20 May, 1966; 3 June, 1966; 19 Sept., 1966; 17 Feb., 1967], No. 15646/67. Heading H3R. A balanced modulator comprises at least two solid state devices feeding a common output load resistance, the input and output terminals all being unbalanced, and the circuit does not include inductances so that it is suitable for construction by printed circuit techniques. In Fig. 1, the modulation signal f passes to the output terminal S via a transistor 5 which is rendered alternately conductive and non- conductive by the carrier frequency input F. The carrier also passes through a phase inverting transistor 12 and another transistor 6 to the point K so that the carrier signal cancels out at this point. A diode 21 conducts when transistor 5 is cut off and thereby maintains the input impedance constant. In a modification, Fig. 2 (not shown), the modulation signal is also supplied to the transistor 12 (42 in Fig. 2) so that the modulation signal is inverted instead of chopped at carrier frequency. In a modification of this arrangement, Fig. 3 (not shown), the third transistor 6 is omitted. In another arrangement, Fig. 4 (not shown), the emitters of two output transistors (130, 140) feeding a common collector load (104) are supplied with anti-phase modulation and carrier frequencies derived from phase-splitting input transistors (110, 120). Modulators using transistors of opposite conductivity.-In one arrangement, Fig. 5 (not shown), the carrier and the modulation are supplied to the bases of two opposite-type transistors feeding a common collector load. In another arrangement, Fig. 6, the modulation signal f is supplied to both emitters, and the carrier signal F is supplied to the emitters through a phase-splitting transistor 304. This arrangement may be modified, Fig. 7 (not shown), to include a further pair of oppositetype transistors which are rendered conductive by the carrier signal when the first pair are non- conductive. Diode modulators.-The carrier signal is applied through a phase-splitting transistor 405, Fig. 8, to alternately open and close a pair of diodes 417 and 418. The modulation is applied at terminal 402 and the output is derived from terminal 403. Diodes 422 and 423 conduct when the main diodes are non-conductive and thereby maintain a constant input impedance. The circuit may be modified, Fig. 9 (not shown), to include a further pair of diodes which are rendered conductive by the carrier signal when the first pair are non-conductive; the modulation is supplied to the two pairs of diodes through a phase-splitting transistor.
