Patent EP-0377883-A1 (EP)
Inventor: ROSSMAIER HENRY DR
IPC: C07H15/04
Filed: 1989-12-22
Abstract: In the process according to the transacetalation reaction with propene-glycol, a saccharide component (B) containing starch or partial starch decomposition products is first added to a reaction medium (A), comprised of at least propene-glycol and an acid catalyst and, optionally, higher (C8-C18) fatty alcohol, said reaction medium being heated to 100 to 130 DEG C. This first produces propene-glycol-glucoside, which is transacetalated with fatty alcohol. The molar ratio of fatty alcohol to propene-glycol is no greater than 1. By a transformation process known per se, a substance which is chromatically stable in the alkaline range and has a high content in C8-C18 alkylmonoglucoside is produced. The quantities of propene-glycol and fatty alcohol recovered by distillation can be recycled without further transformation steps.

Abstract: An apparatus is described for optically scanning an information plane (2) in which a radiation beam (b) emitted by a diode laser (4) is focused by a lens system (6) on the information plane and the radiation reflected by this plane is focused,  via  a composite diffraction grating (9), into two radiation spots (V₁, V₂) each cooperating with a separate detector pair (18, 19; 20, 21). The separating strips (22, 23) of the detector pairs are parallel, thus providing fairly wide tolerances in the positions of the elements (9, 20) while the apparatus is satisfactorily corrected for wavelength variations of the radiation beam (b).

Abstract: A slant plate type compressor is disclosed having a plurality of cylinders (70) formed around the periphery of a cylinder block (21) and a piston (71) slidably fitted within each of the cylinders for reciprocation by a drive mechanism (26). The drive mechanism includes a drive shaft (26) rotatably supported in the compressor housing, a rotor (40) coupled to the drive shaft and rotatable therewith, and a coupling mechanism (50,60) for drivingly coupling the drive to the pistons such that the rotary motion of the rotor is converted into reciprocating motion of the pistons. The coupling mechanism includes a plate (50) having a surface disposed at a slant angle relative to the drive shaft. The slant angle changes in response to a change in pressure in the crank chamber to change the capacity of the compressor. A bias spring (34) is mounted on the drive shaft located between the slant plate and the cylinder block to urge the slant plate toward the maximum slant angle. An inner diameter of the cylinder block end of the bias spring is smaller than a diameter of the drive shaft in order to firmly secure the cylinder block side end portion of the bias spring to the drive shaft.

Abstract: A two-stroke internal combustion engine has two cylinders (2) in V-configuration with a blower (20) supplying air to the cylinders through a hollow rotary valve (16) constituting part of an air intake manifold. Inlet ports (11) in the cylinder walls extend in the axial direction beyond exhaust ports (12) so that air enters the cylinders after closure of the exhaust ports on the piston upstroke. The rotary valve prevents entry of exhaust gases into the intake manifold during piston downstroke.

Abstract: An improved process is provided for the production of nitriles and oxides from hydrocarbons by reaction with oxygen, air or a gas enriched in oxygen relative to air, preferably the latter, and ammonia where a nitrile is desired, in the presence of a suitable catalyst. An alkane, e.g. propane, is converted to an alkene in a catalytic dehydrogenator. The product stream is introduced into an ammoxidation/oxidation reactor. The product formed therein is recovered in a conventional quench tower. The gaseous effluent from the quench tower is treated in a separator to produce an alkane/alkene stream ('the first stream'), a waste stream ('the second stream'), an oxygen stream ('the third stream') if desired, a hydrogen stream ('the fourth stream'). The oxygen stream may be recycled to the ammoxidation/oxidation reactor depending on the nitrogen content thereof. The first stream plus at least a portion of the fourth stream is introduced Into a selective oxidation unit to remove the remaining oxygen and then recycled to the dehydrogenator. The remainder of the hydrogen stream, if any, may be taken as product or vented. The dehydrogenator may be a multistage dehydrogenator wherein the product stream is withdrawn from a reactor other than the first and last reactors, the recycle streams are introduced into the next sequential reactor and the effluent from the last reactor is introduced into the first reactor, a reactor having a similar alkene composition, or directly into the ammoxidation/oxidation reactor.

Abstract: Un procédé et des substances permettant de réduire la poix dans les opérations de réduction en pâte et de fabrication de papier, notamment dans des compositions obtenues au moyen de procédés mécaniques de réduction en pâte, contenant de la pulpe de bois dans des quantités supérieures à environ 10 % en poids. Le procédé comprend l'addition à une matière première contenant de la poix, d'une substance composite particulaire dispersible dans de l'eau, stable, préparée par adsorption irréversible d'un polymère cationique soluble dans l'eau, par exemple, un poly(chlorure de diallyldiméthylammonium), sur un susbtrat particulaire sensiblement insoluble dans l'eau, par exemple du kaolin, rendant ainsi le polymère cationique insoluble et immobile. Le polymère cationique est suffisamment électropositif de sorte que la substance composite particulaire de régulation de poix présente un potentiel zêta d'au moins environ +30 mV, et de préférence d'environ +60 mV à environ +80 mV, la quantité de la substance composite ajoutée à ladite matière première étant efficace pour disperser finement la poix se trouvant dans une feuille de papier produite à partir de ladite matière première, en vue d'une élimination sous forme d'agrégats la contenant finement dispersée. On peut améliorer davantage la régulation de poix à l'aide de ces substances composites particulaires, de régulation de poix, avec de l'alum et/ou des polymères d'oxyde d'alkylène de poids moléculaire relativement élevé. On peut également obtenir d'autres effets désirables, comprenant la rétention améliorée de fines, un meilleur drainage ainsi que des coûts inférieurs de traitement de déchets par la mise en oeuvre de cette invention.

Abstract: With a gas closure valve (18) for plastic processing apparatuses, in order to avoid streaking in the moulding even at very high gas pressures, and to ensure high flexibility in production without change-times, it is proposed for the valve needle (40) to be controlled by a control plunger (60), which for its part is controlled by means of a working gas volume. When material is fed to the mould (16), the valve needle (40) closes material-tightly, whereas when gas is returned the valve needle (40) remains open until the gas bubble formed in the cavity of the mould (16) has been completely discharged.
