Abstract: Process for the purification of carboxylic acid esters containing aldehydes, acetals and/or unsaturated compounds, which have been obtained by reaction of olefinically unsaturated compounds with carbon monoxide and alkanols, in which the carboxylic acid esters containing aldehydes, acetals and/or unsaturated compounds are treated at elevated temperature with hydrogen and acidic agents in the presence of at least one metal of the 8th group of the periodic table and the low-boiling and/or high-boiling components formed are removed by distillation, characterised in that the carboxylic acid esters containing the aldehydes, acetals and/or unsaturated compounds
       a) are treated with strongly acidic agents in a first step at a temperature of 20 to 200 DEG C and
       b) the mixture thus treated is hydrogenated in a second step in the presence of at least one metal of the 8th sub-group of the periodic table at a temperature of 50 to 200 DEG C and under a pressure of 1 to 50 bar.

Abstract: A high-pressure fluid processing device (1) is provided, which is improved for application of impinging fluid jets to process an object, such as a woven fabric, to increase uniformity of application and processing of the object. Particularly, the present invention is useful for processing woven fabrics having small thicknesses and lower densities by compensation for overlapping regions that occur during high-pressure fluid processing. The high-pressure fluid processing device (1) includes a header means (3) that is translationally rotationally driven from a frame (2) so as to move a plurality of nozzles (7) thereon in circles to impinged the object conveyed thereunder with high-pressure fluid jets. Moreover, the device includes masking members (10) that are positioned between the nozzles (7) and the object to be processed so as to block at least some of the jet flow of fluid to increase uniformity of processing and to avoid unwanted bunching or shifting of fibers in a processed fabric.

Abstract: Method for converting a first data word stream furnished at the rate of a first clock and a second data stream comprising, inside successive frames, a sequence of n data words from the first stream and accompanying data, the duration of each frame of the second stream being equal to the duration of n data words in the first stream. This method comprises the steps consisting in:
 - storing successive data words from the first stream in an input register (1),
 - once the register is full, writing its contents to one of p intermediate registers (A, B, C),
 - sequentially reading the p intermediate registers from an output register (5),
 - if, in the course of a frame, the sequence of operations of writing to and reading from the intermediate registers is such that an intermediate register is read although its write operation has not been modified or is undergoing modification, skipping, at the start of the next frame, one reading order until a suitable synchronisation is arrived at which will then be maintained during the subsequent frames.

Les membranes sont adossées à des chambres ou plénums d'air (32, 33) qui possèdent des éléments de support (34) pour tenir en position les membranes. Une pression réduite est appliquée aux plénums pour extraire du gaz dissout de l'encre dans le chemin d'encre sans accumulation de crasse sur les surfaces des membranes. Une pression accrue peut également être appliquée aux plénums pour éjecter de l'encre de la tête à gicleur d'encre dans le but d'effectuer une purge. Dans la tête à gicleur d'encre, l'encre circule par convection de l'orifice (35) vers le chemin de désaération (27) même lorsque le gicleur n'envoie pas d'encre.

Abstract: A static whipping device (10) and process for intermixing of a whippable liquid and a propellant gas under pressure to produce a whipped product. The device includes a pressure chamber with a top and a bottom and a valve (38) for introducing a propellant gas and for dispensing a whipped product. The valve is adjacent the top of the container. A static mixer for intermixing the whippable liquid and the propellant gas is disposed in the chamber. It includes an elongated tubular member (54), preferably formed of plastic, having one end connected to the valve for dispensing the whipped product and the other end extend­ing to near the bottom of the chamber. It further includes an internal mixer (64, 66) disposed within the tubular member and adjacent the top of the container. An aper­ture (62) is disposed in the tubular member adjacent the internal mixer for permitting a limited amount of the propellant gas to enter the tubular member. The aperture is disposed in the upper portion of the elongated tubular member and is in communication with the charged propel­lant, whereby when the dispensing valve is open, the pressurized whippable liquid flows through the tubular member and the internal mixing means and by the aperture where it is intermixed with the propellant gas that bleeds through the aperture to intermix with and agitate the whippable liquid, the agitation and intermixing con­tinuing through the tubular member to produce a whipped product.

Abstract: A thin-film memory element is made of a thin-film transistor. The memory element has two gate-insulating films (62, 65), and two gate electrodes (G1, G2) formed on the gate-insulating films (62, 65), respectively. The first gate-insulating film (62) can accumulate elec­trical charge, whereas the second gate-insulating film (65) cannot. A first gate electrode (G1) on the first gate-insulating film (62) is used as write/erase electrode, and a second gate electrode (65) on the sec­ond gate-insulating film (65) is used as read electrode. Since the memory element has two gate electrodes (G1, G2), one for writing or erasing data, and the other for reading data, its threshold voltage remains unchanged. Hence, data can be read from the thin-film memory ele­ment for a virtually indefinitely long period of time.
