Abstract: 1,192,681. Isomerization of hop α-acids. " COOPPAL ET COMPAGNIE-POUDRERIE ROYALE DE WETTEREN " and M. VERZELE. 10 Jan., 1968 [12 Jan., 1967; 28 Dec., 1967], No. 1381/68. Heading C2C. [Also in Division C6] Hop α-acids are isomerized into iso-α acids in the presence of isooctane or methyl cyclohexane. (1) A solution of α-acids in isooctane or methyl cyclohexane, derived either directly from hops or from a hop extract, is rendered alkaline with sodium carbonate, the mixture is boiled for 90 minutes under reflux to effect the isomerization, the reaction mixture is acidified with sulphuric acid, and an organic phase is separated from an aqueous phase and evaporated until a syrupy paste containing the iso-α acids is obtained. (2) In this embodiment the iso-α acids are extracted directly from the aqueous phase of the reaction mixture. Thus, the aqueous phase is acidified to pH 7 and then treated with isooctane or methyl cyclohexane, the aqueous and organic phases are separated, the aqueous phase is brought to a pH of 3 and the iso-α acids recovered therefrom by methylene chloride. The liberated iso-α acids may be treated with sodium or potassium carbonate to obtain the corresponding sodium and potassium salts, which are more soluble in water than the free iso-α acid.

Abstract: 538,382. Cathode-ray tubes. STANDARD TELEPHONES & CABLES, Ltd. Jan. 30, 1940, No. 1854. Convention date, Feb. 11, 1939. [Classes 39 (i) and 40 (v)] A distributer for a multiplex signalling system comprises a cathode-ray tube with a number of secondarily emissive targets on which the ray is directed in succession and a common collecting anode. For transmission the potentials of the several targets, and consequently the emission therefrom are controlled in accordance with the separate signals and the anode is connected to the transmission line ; for reception the input is connected to the cathode and a modulating electrode and the separate signal circuits are connected between the ' targets and the anode. Fig. 3 shows a tube in which the ray is caused by the deflecting plates 50, 51 to travel in a circular path over the targets 54, the signal potentials being applied between the targets 54 and the anode 52; the leads 58 to the conductors 54 are screened by a plate 57, coated with fluorescent material to assist in focusing the ray. The sector shaped targets may be replaced by strips extending lengthways of the tube. In a modification the targets are formed on the surface of a single plate and the signal potential are applied to grids which the ray traverses on its way to the target. Figs. 18 and 19 show a further modification in which the targets are formed by sector shaped portions to 435 of metal plate 433, separated by portions 434 coated with a non-emissive material such as graphite. Corresponding to each target is a deflecting plate 438, and modulation is effected by deflecting the ray so that it passes over a wider or narrower portion of the target. The deflector plates are surrounded by a screen 440 and separated by radial screens 444. Fig. 4 shows a construction of electron gun. The cathode 35 is enclosed in a cylindrical electrode 37 secured to an insulating member 39 carried on rods 33.
