Patent EP-0084384-B1 (EP)
IPC: B29C67/20
Filed: 1983-01-04
Granted: 1986-04-23
Abstract: A process for the continuous foaming of plastics, especially polyurethane, of the type in which the foaming space is delimited by flexible material bands which are fed together with the bun of foamed material being formed. As flexible material for these bands a composite web is used which comprises a support paper band and a thin impermeable band of plastics, preferably polyethylene having a thickness from 5 to 40 microns. The two bands of which the flexible is composed have a reduced adhesion to one another. The paper band is then detached from the bun of foamed material by disengaging it from the band of plastics which is left permanently adherent to the foamed material or is detached from this latter in an operation subsequent to the detachment of the paper band. In this way, losses of material are avoided, and the paper of the paper bands can be recovered.

Abstract: An object is manufactured from a powdered material by isostatic pressing of a body, preformed from the powdered material, with a pressure medium, whereby the preformed body, in which at least the surface layer consists of a ceramic material in the form of a nitride, is surrounded by a casing which is rendered impenetrable to the pressure medium, before the isostatic pressing is carried out and the powder sintered. As the material in the casing there is used boron oxide or a glass containing boron oxide or a material forming glass while being heated, in which the content of boron oxide is sufficiently high for the glass-or the glass formed during heating-to be removable by water. The preformed body surrounded by the casing is subjected to a heat treatment for the formation of boron nitride on the surface of the preformed body, before the isostatic pressing is carried out. The casing is removed from the finished product by means of water or water vapor.

Abstract: In internal combustion engines (1), the sealing of the combustion chamber by pistons and piston rings is not absolute. Throughout the working cycle, gases from the cylinder enter the crankcase (1a). These blow-by gases must be able to escape from the crankcase (1a). In a device for returning the blow-by gases into the system of an internal combustion engine (1) supercharged with a gas-dynamic pressure-wave supercharger (10), it is envisaged that a gas delivery unit designed as an ejector (20) generates a reduced pressure in the crankcase (1a). The ejector (20) is operated with a propellant gas from a line (16) which is taken from the supercharger airline (13), a control (8) placed in the propellant gas line (16) ensuring that the reduced pressure in the crankcase (1a) never exceeds a defined value. The blow-by gases in the line (2) flow through an oil separator (4) and, mixed with the propellant gas in the line (16), are then returned into the exhaust line (15) of the engine system.

Abstract: In an analog input circuit which samples and holds a predetermined component sampled from an input signal, an operational amplifier of an active filter (11) is constituted by two-stage voltage-follower circuits (15), (16) series-connected through a switch (17), in order to simplify the circuit configuration by the integration of the filter and sample-and-hold circuit which are usually provided individually. A holding capacitor (18) is provided at the output terminal of the switch (17). When the switch (17) is closed, the potential of the holding capacitor (18) is the same as that of the output of the active filter (11). When the switch (17)is open, the potential of the holding capacitor (18) is output and maintained from the active filter (11). This analog input circuit is suitable for use in a digital protective relay to which a plurality of analog signals are input.

Abstract: Un système mélangeur de gaz comprend une soupape (10) de mélange proportionnel ayant un élément de soupape mobile entre une première et une deuxième limites de déplacement correpondant respectivement à des pourcentages minimal et maximal d'un gaz dans le mélange. La position de l'élément de soupape est détectée par un mécanisme de détection (40, 42) qui produit un signal de détection transmis à un micro-ordinateur (54). Le micro-ordinateur (54) reçoit également un signal de commande (60) qui représente un pourcentage voulu d'un des gaz à melanger. Le micro-ordinateur (54) calcule une position voulue de l'élément de soupape en fonction de la valeur du signal de commande (60), et génère un signal d'entraînement (64) en fonction d'une comparaison effectuée par le micro-ordinateur (54) la position détectée et la position voulue de l'élément de soupape. Un moteur (36) entraîne l'élément de soupape jusqu'à la position voulue en réponse au signal d'entraînement (64). Le système comprend également un accumulateur (30) pour accumuler un volume sélectionné du mélange gazeux qui s'écoule par l'orifice d'évacuation de la soupape (10) avant que le mélange ne soit fourni en réponse à une demande en aval. L'accumulateur (30) augmente la capacité maximale effective d'écoulement du système, tout en "égalisant" des changements temporaires de la demande d'écoulement en aval avant que les effets de ces changements ne soient ressentis au niveau de la soupape (10).
