IPC: H04N9/09
Filed: 1957-03-22
Abstract: 886,016. Television. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 13, 1958 [March 22, 1957; Dec. 27, 1957], Nos. 9384/57 and 40149/57. Class 40(3). [Also in Group XX] In a colour television camera image light is directed via an appropriate one of the lenses carried in a turret 15, dichroic elements 12, 13 and, plane mirrors 14, 14a (Fig. 1) on to pick-up tubes 1, 2, 3 producing, respectively, blue, green and red representative signals and each of which has associated therewith a respective (short focal length) objective lens 6, the arrangement being such that the combination of the turret lens and an objective lens produces an effective lens of different focal lengths from that of the objective lens alone. The pick-up tubes together with their focusing and scanning coil assemblies 4 are carried by a plate 5 the position of which is adjustable (by means not shown) to vary the distance between the tubes and the objective lens 6 for optical focusing. The objective lenses are carried by a fixed plate 7 each lens being provided with a hood 8 which is attached to the iris control ring so that adjustment of the aperture may be effected by rotation of a control knob 9 the shaft 10 of which carries worm gears meshing with gears on the outsides of the tubes 8. To enable the objective lenses 6 to be of identical focal lengths the optical paths of the pick-up tubes are made equal to one another by appropriate positioning of the lenses with respect to the dichroics 12, 13 and the mirrors 14, 14a. Fig. 2 shows an alternative constructional arrangement which requires only one plane mirror 14 the latter, in this embodiment being arranged to allow transmission of a small proportion of the light incident upon it to enable an eye piece 24 to be used as a view finder. In each embodiment the turret, which is operated by a control handle (shown only in Fig. 2), is provided with a plurality of lenses and may include merely a glass plate 20 (shown only in Fig. 2) a "negative" lens such as 19 being employed when a wide angle of view is required. To prevent the formation of secondary images of the incorrect colour due to the reflection of light from the back surfaces of the dichroics colour filters 22, 23, shown only in Fig. 2, transmitting blue and red light respectively are positioned in front of the pick-up tubes 1 and 2. To reduce registration errors between the signals generated by the tubes, due to the different deviations produced by the lenses for light of different colours producing images of different sizes, the sizes of the scanned areas may be varied by means of a switch operated by the turret control handle.

Abstract: 351,491. Cables. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.-(Assignees of Nyquist, H.; Marion Avenue, Millburn, New Jersey, U.S.A.) March 26, 1930, No. 9643. Convention date, July 20, 1929. Drawings to Specification. [Class 36.] In order to reduce far-end cross talk in a multiconductor telephone cable for two-way working, the conductors of the two speech directions are arranged in separate concentric cylindrical groups separated by a shield of magnetic and conductive material. The shield, which comprises several layers of thin wide tape applied helically with a short pitch about the inner group of conductors, is formed of a material, such as soft iron, having a high product of permeability and conductivity, and a ratio of permeability to conductivity substantially different from that of the conductors. In order to increase the conductivity of the shield, the magnetic tape may be coated with a layer of highly conductive material such as tin, zinc, copper, lead, silver, gold, nickel or chromium. The coating may be applied only to the overlapping portions of successive helices. In order to avoid magnetization of the shield due to longitudinal currents, the shield may be insulated from earth at the terminals of a repeater section.

Title: Improvements in the treatment of benzol obtained by pyrolysis
IPC: C07C15/04
Filed: 1930-03-26
Abstract: Benzol obtained from methane, ethane, and like gases by pyrolysis is refined to give higher yields of motor spirit by first separating a high-boiling fraction which contains the greater part of the unsaturated hydrocarbons, hydrogenating this fraction, and then refining the fractions separately or mixed. For example, the 5 per cent of the crude benzol forming the 135-150 DEG  C. fraction is hydrogenated in the liquid or vapour phase at atmospheric or high pressures, preferably in presence of nickel or of molybdenum compounds or other catalyst immune from poisoning by sulphur; ethyl benzene, ethyl cyclohexane, and other saturated compounds are formed from the unsaturated hydrocarbons.  The product alone or mixed with the crude benzol fraction boiling up to 135 DEG  C., is refined by passing it in vapour form through a bed of bauxite, or by sulphuric acid and alkali, or by both processes.

Title: Improvements in processes for producing acyl and sulphonyl substituted piperazines and salts thereof
IPC: C07D295/182
Filed: 1944-05-22
Abstract: (a) N-monosubstituted acyl, acidyl and sulphonyl piperazines are obtained in improved yields as salts by treating piperazine in a solution kept homogeneous throughout reaction with an acyl anhydride, an acyl halide or an arylsulphonyl halide.  Specified reagents are acetic, phthalic and succinic anhydrides, benzoyl bromide, butyryl chloride, ethyl chlorocarbonate, toluene-p-sulphonyl chloride and p-acetamidobenzene sulphonyl chloride, suitable solvents being aqueous alcohol, aqueous dioxane, bromide, butyryl chloride, ethyl chlorocarbonate, toluene-p-sulphonyl chloride and p-acetamidobenzene sulphonyl chloride, suitable solvents being aqueous alcohol, aqueous dioxane, aqueous acetone and, where acetic anhydride is used, glacial acetic acid.  Mixtures are formed thereby, containing additionally to unsubstituted and symmetrically disubstituted piperazine, considerable quantities of N-monosubstituted piperazine, separation being effected by utilising the inability of the diacyl or disulphonyl piperazines to form salts and the differing solubilities of the salts of monoacyl and monosulphonyl piperazine and of unreacted piperazine.  If reaction is conducted with an acyl, or with a sulphonyl halide, the hydrohalide salts are formed during the principal reaction, but employment of an anhydride necessitates adding to the reaction mixture a strong acid, e.g. hydrochloric, sulphuric or oxalic acid, to permit salt-formation and successive extraction of the products; N,N1-unsymmetrically disubstituted are formed by treating the separated monosubstituted compound with an alkyl-, phenacyl- or substituted phenacyl halide, nitrourea, an isocyanate, a salt of thiocyanic acid, an isothiocyanic acid, a salt of an S-alkyl isothiourea or an agent containing an acyl or sulphonyl radical different from that present in the monosubstituted compound. Such derivatives are not claimed in the Specification.  Numerous examples are given.  Specification 578,342 is referred to.
