Abstract: A process for modifying the surface characteristics of a preformed polymeric substrate to impart hydrophilicity, hydrophobicity or other desired properties thereto comprises peroxidizing and hydroperoxidizing the surface of said preformed substrate using ozone, directing the subsequent graft polymerization of selected ethylenically unsaturated monomers essentially solely to the surface of said substrate to achieve the desired alteration of substrate surface characteristics while maintaining substrate structural integrity. Substrates so modified are useful in biomedical devices, semipermeable membranes, films, fibers and especially contact lenses.

Abstract: A power conversion machine comprising a rotor as­sembly having a first rotor part (124) with a first pair of pistons (137, 138) and a second rotor part (125) with a second pair of pistons (135, 136) which are rockable back and forth in relation to the first pair of pistons in the machine housing (10, 110). The first rotor part is con­nected to the rotary shaft (117) of the machine, while the second rotor part (125) is non-rotatably connected to the first rotor part (124) and rockable in relation to the first rotor part. Consequently the first rotor part and the second rotor part are jointly rotatable about said axis of rotation. The first rotor part is rotatable in a first path of revolution, while the second rotor part is movable in a second path of movement which deviates from said path of revolution. The first and the second rotor part (124, 125) are defined inwardly of a common spherical generatrix. A guide means (116) for guiding the second rotor part (125) in a second path of revolution is ar­ranged centrally within the rotor assembly (124, 125) in rigid connection with the machine housing.

Abstract: A process for the preparation of salts of dialkyl sulphosuccinates in aqueous dispersion or solution is described. In the process, a dialkyl maleate or fumarate is reacted with an alkali metal sulphite in aqueous dispersion using a certain amount of the salt formed as the reaction product as dispersant. The reaction is carried out in the presence of an alkali metal hydroxide at a temperature of 120 to 150 DEG C. The process has the advantage of a homogeneous reaction procedure in combination with short reaction times. By carrying out the reaction in a sealed vessel, the emission of SO2 is prevented. The salts formed can be used as emulsifiers or wetting agents.

Abstract: An image forming apparatus is provided with an original density detecting device (4) for detecting the original density, and output characteristic switching means (1, 6) for switching the output characteristic relative to the original density detected by the original density detecting device (4) to a plurality of types of predetermined output characteristics (a, b, c). The original density is found on the basis of a predetermined output characteristic out of the plurality of output characteristics of the original density detecting device (4) and an output of the original density detecting device. Then, an output characteristic showing a high rate of change in the vicinity of the original density found by the first original density measuring means out of the plurality of output characteristics is selected by selecting means (1). When the selected output characteristic is different from the output characteristic used for measuring the original density by the first original density measuring means, the output characteristic of the original density detecting device (4) is switched to the selected output characteristic, and the original density is found on the basis of the selected output characteristic and the output of the original density detecting device (4) by second original density measuring means.

Abstract: 2.1 Relaying systems with conference devices are known, where a composite signal is formed from speech samples of the conferees, a speech intensity is determined for each conferee and the respective proportion of the composite signal is defined. The speech intensities of the speech samples are measured. A conferee whose speech intensity exceeds a predefinable threshold is categorised as speech-active. The acoustic impression of the reproduction is not always felt by some conferees to be "natural". …<??>2.2 It is proposed in this context that a speech intensity be determined for the composite signal and that, to determine the proportion of the speech sample of a conferee in the composite signal, the speech intensity of the conferee be compared with the speech intensity determined for the composite signal. …<IMAGE>…

Abstract: 3-dimensional observation is carried out on the atomic arrangement and atomic species in a thin-film specimen at an atomic level in order to clarify the existence states of defects and impure atoms in the crystals. For that purpose, an instrument and a method for 3-dimensional observation of an atomic arrangement are implemented by a system comprising a scanning transmission electron microscope equipped with a field emission electron gun (8) operated at an acceleration voltage of greater than 200 kV, a specimen goniometer/tilting system (12) having a control capability of the nanometer order, a multi-channel electron detector (13) and a computer (14) for executing software for controlling these components and 3-dimensional image-processing software. Point defects and impure atoms, which exist in joint interfaces and contacts in a ULSI device, can thereby be observed. As a result, the causes of bad devices such as current leak and poor voltage resistance can be analyzed at high accuracy.
