Abstract: 5 n7 A conducting reflective material (12) serving as a reflective member of a reflector and a fiber-compounded thermosetting resin serving as a back support member (10) are poured into a mold comprised of a core mold (18) and a cavity mold (19) for molding the reflector, so as to form a resin molded material as an integral unit under heat and pressure. Thereafter, the mold is released from being pressurized, or subjected to a reduction in pressure. Then, a thermosetting resin (20) for forming a surface protective layer is injected between the surface of the core mold and the resin molded material, and the contents of the mold are subjected to heat and pressure again, so as to integrally form a reflector comprising the respective resins referred to above and the reflective material. As a consequence, the number of steps required for charging the mold with the resin used to form the surface protective layer can be reduced and unwanted variation in color can be prevented. In addition, the surface protective layer on the reflective surface of the reflector can be uniformly formed.

Abstract: A servovalve controlled by a magnet armature and operated by its own fluid. A pressure space (5) connected to the valve inlet (Z) is arranged on one side of the differential piston (2) carrying the valve plate (3) while a control space (6) is arranged on the other side. The control space (6) is connected via a relief hole (2.1) in the differential piston (2) to the valve outlet (A) and via a control hole (2.2) to the pressure space (5). With the magnet coil (11) excited, the relief hole (2.1) is closed off by the magnet armature seal (8.1). A first return spring (9) is arranged between the magnet armature (8) and an axially displaceable head piece (12), and a second return spring (14) is arranged between the head piece (12) and a fixed stop (10.2). The head piece (12) is supported directly, via spacers (15, 16), on differential piston (2). When the magnet armature (8) is attracted, relief hole (2.1) opens, the differential piston (2) rises and, during the opening movement, lifts the head piece (12) together with the magnet armature (8) via the spacers (15, 16) without altering the magnetic conditions. As a result, it is possible to control the valve with an exceptionally small electric current. <IMAGE>

Abstract: Foam typically forms in a receiving tank (10, 110) from either the underflow or overflow from a gas sparged hydrocyclone (12). Particularly in processing of paper pulp to deink the pulp or to remove sticky contaminants from it, the foam in the receiving tank has many undesirable materials which are preferably removed. Foam from the receiving tank (10) is removed with a vacuum box (29) or an overflow weir. To facilitate concentration of the foam, the discharge of fluent material from the bottom (27) of the receiving tank is preferably via a tangential discharge line (26) so that a swirling action takes place in the tank and the foam collects near the cylindrical side wall (24) of the tank. The foam may be removed by vacuum caused by a blower 32), and the foam and entrained liquid is separated from the air (at 34) before the air reaches the blower. The foam and entrained liquid may be dewatered, or compounds therein having a high BOD and COD load are separated. An alternative construction of receiving tank (110) includes a gas introduction device (51) at one side portion causing gas to blow foam toward an opposite side portion to a foam outlet (58), with a liquid spray (from 59) for breaking foam bubbles at the outlet. A generally horizontal baffle (55), and optional vertical baffles (53, 56), prevent short circuiting of fluent material from an inlet (123) to the fluent material outlet (126) of the tank.

Abstract: Technique d'analyse et appareil de détection de la réaction entre un matériau récepteur et un analyte, où la réaction elle-même produit un signal d'interférence optique. La technique d'analyse se fonde sur l'affinité de l'analyte pour le ligand récepteur. La réaction qui intervient entre les deux partenaires de liaison spécifiques permet d'effectuer une détection qualitative et/ou quantitative de l'analyte chimique, biochimique ou biologique dans un échantillon. Un appareil d'analyse préféré comprend (a) un substrat dont la surface présente des reflets diffus et est recouverte de couches optiques antireflet; (b) une mince couche de matériau antireflet activé pour lier le matériau récepteur; (c) une couche de matériau récepteur pouvant interagir avec les espèces à analyser. Les composants a-c permettent de produire une surface préformée optiquement active par rapport à la lumière au moins sur une certaine bande de longueurs d'onde. La technique d'analyse consiste (d) à mettre la surface préformée en contact avec l'échantillon, et (e) à observer les propriétés optiques de la surface préformmée afin de détecter visuellement un changement des propriétés optiques de ladite surface, changement résultant de la liaison entre l'analyte présent dans l'échantillon et le matériau récepteur.

Abstract: Une machine à étiqueter comprend au moins un plateau rotatif commandé (1) et un piston (2) levable et abaissable, commandé, entre lesquels l'objet à étiqueter, par exemple une bouteille (24), est fixé de manière qu'il ne puisse pas tourner. Un dispositif (3) de mise en rotation associé au piston le fait tourner jusqu'à une position angulaire déterminée et/ou le maintient dans cette position angulaire, lorsque le piston n'est pas en contact avec l'objet à étiqueter. Par contre, lorsque le piston est en contact avec un objet à étiqueter, il est séparé du dispositif de mise en rotation et peut tourner librement avec l'objet à étiqueter entraîné par le plateau. Un tel dispositif de mise en rotation peut être aisément construit et permet une utilisation polyvalente de pistons asymétriques, ayant une position préférée. C'est par exemple le cas de pistons ayant des surfaces adhésives pour étiquettes faisant saillie, de pistons ayant des évidements entourés par les extrémités des étiquettes faisant saillie, de pistons ayant des doigts de préhension des étiquettes, parmi d'autres.

La première solution consiste à subdiviser la fente de commande (13) en plusieurs rainures (27, 28) du côté de la pression, reliées au moins en partie par des soupapes de non retour (32) au raccord de refoulement (20). Une autre solution consiste à adapter la forme de la fente de commande du côté de la pression au mode optimal de fonctionnement; son extrémité d'admission est relativement étroite afin de réduire le bruit (réduction du bruit à des régimes élevés) et son extrémité de sortie a une largeur suffisante pour assurer la puissance requise. Une troisième solution consiste à prévoir une fente (12) du côté d'aspiration ayant une forme analogue et correspondant à celle de la deuxième solution, qui influe en outre par sa longueur sur le degré de remplissage de l'alésage du piston.

Abstract: A feedforward controlling method for driving a servomotor smoothly and stably by improving the follow-up ability to a command of a servosystem. The method can be adapted to servosystems in which a position and speed loop processing is repeated plural times during a period for distributing the movement commands of a host controlling device. A temporary speed command, which is the product of the gain (Kp) and the deviation (e) between a movement command (a) and an actual rotational quantity (Pf) of the motor in each period of the position and speed loop processings, is calculated. A positional feedforward quantity, which is the product of a factor (α₁) and the average value of the movement command in each processing period and the movement commands in the periods before and after the processing period, is calculated. Then, a speed command is calculated by correcting the temporary speed command with the positional feedforward quantity. Further, a temporary torque command is calculated in the speed loop which has an integration term (2) and a proportion term (3). A speed feedforward quantity, which is the product of a factor (α₂) and the differentiated value of the value which is obtained by lead-compensating the average value of the movement commands with a lead compensating element (8) by a time equal to a multiple of the processing period by a predetermined number. Then, a torque command for driving the servomotor (4) is obtained by correcting the temporary torque command with the speed feedforward quantity.

Abstract: A process for producing scaly or acicular silica gel having relatively large and controlled pore volume and specific surface, which comprises freezing silicic acid sol to deposit the crystallized sol in a gap between the faces of solvent crystals to thereby form frozen scaly or acicular silica gel, thawing the frozen silica hydrogel, conducting hydrothermal polymerization thereof, and drying the resultant hydrogel. This process is advantageous in that the shape control is possible with inexpensive silica sol by controlling the gelation time of the sol, that freeze drying is unnecessary, and that the physical properties of the silica gel can be controlled by conducting thawing, water washing and hydrothermal polymerization after freezing.
