Abstract: In bulk ccd's the non-linearity in the input characteristic caused by varactor effects is removed by moving the potential well in which the charge packets are generated below the input electrode to the surface where the centre of electrical charge is substantially independent of the value of the charge. Said shift can be obtained by external means, for example an extra d.c. voltage at the input electrode, or by internal means, for example thicker oxide below the input electrode.

Abstract: An installation for timing with television pictures comprises two television cameras (I, II), means for counting the time for a timing (1-5, 11-19), command means (10), and a video recorder (24). In the picture-taking mode, said time counting means deliver to said cameras image scan start pulses at the rate of 50 per second and with a shift of 10 ms from one camera to the other. An image, from one camera or from the other, thus starts every hundredth of a second. The video recorder (24) is of a standard type, the number of heads of which has been doubled, an arrangement which increases the speed of movement of the magnetic tape and/or which refines the magnetic inscription of the video information permits an interlaced recording of the video information from the two cameras, on a single magnetic tape in a single video recorder. This installation permits the economic concentration of a precise time measurement and a television standard transmission. <IMAGE>

Abstract: A double heterostructure semiconductor laser having the configuration of its optical cavity arranged to impose a constraint on the lasing filament as the spatial distribution of the lasing filament changes from that occuring at the start of the lasing regime, so that the optical flux emitted by the laser has self-saturating properties. 
     This protects the laser from catastrophic facet erosion and enables a simpler control circuit to be used to drive this laser when it is used as a light source for an optical communications system.

Abstract: A process for oxidizing organic substrates such as ketones and ethylenically unsaturated compounds. The substrate is contacted with aqueous hydrogen peroxide in a solution or in a two-phase liquid system, in the presence of a polymeric catalyst containing chemically bonded arsenic. This process can lead to lactones or hydroxy acids from cyclic ketones or to esters or mixtures of alcohol and carboxylic acid from open chain ketones. Unsaturated compounds afford epoxides and/or diols. Preparations of certain polymers substituted by arsenic groups, particularly from polystyrene, poly(vinylpyridine) and copolymers thereof, useful as catalysts in such oxidation process, are described. For example, polystyrene is brominated, bromine therein is replaced by lithium and the resulting lithiated polymer is converted into a polymer containing an arsenic group, such as arsono, -As(O) (OH) 2 , as substituent group, by reaction with arsine triethoxide followed by oxidation and hydrolysis by aqueous hydrogen peroxide. The aromatic polymers, polyphenylene and polymers and copolymers of vinylpyridine, can be used similarly as the catalyst.

Abstract: A process for the preparation of an immunoglobulin solution containing IgM in concentrated form and suited for intravenous administration, comprising treating an IgM-containing protein fraction obtained by conventional fractionation from blood plasma or serum with  beta -propiolactone in an amount such that the ratio of beta -propiolactone to a 5% solution of the IgM-containing proteins is from about 0.05 to 0.15 ml per 100 ml. Advantageously, prior to the treatment with  beta -propiolactone the IgM-containing protein fraction is freed of lipids by treatment with colloidal silica gel and with crosslinked dextrans or diethylaminoethyl cellulose. The starting material used is a Cohn fraction III of human blood plasma which has been dissolved in physiological saline solution to a concentration of about 5% protein, the treatment with  beta -propiolactone is carried out at about 20 DEG  to 37 DEG  C. for about 4 to 6 hours until a substantially constant pH of about 8 is obtained, and the solution is thereafter sterile filtered.
