Patent EP-0056112-A1 (EP)
Inventor: OYAMADA AKIRA
IPC: B22C1/22
Filed: 1981-11-26
Abstract: In preparing a resin coated sand for use in sand mold casting processes by a hot-melt process using an unsaturated polyester which is solid at room temperature as the coating material, a solution of an organic peroxide as a polymerization initiator for the unsaturated polyester is introduced into the mixture of heated foundary sand and the unsaturated polyester while the polyester is in the state of liquid coating on the sand particles, and stirring is continued to uniformly mix the solution with the unsaturated polyester and evaporate and dissipate the solvent before solidification of the polyester coating as the result of cooling of the mixture. The polyester coating contains no liquid cross-linking agent, so that the resin coated sand is untacky and high in fluidity at room temperature and, therefore, can be filled into a die cavity to shape a sand mold or core with sufficiently high bulk density.

Abstract: a) The reaction under pressure, such as cooking or hydrolysis, involves delivering under pressure, by means of a pump, a liquid mixture obtained by diluting substances of vegetable origin with the liquid in the presence of which the intended treatment is to take place. b) Provision is made to subject these substances, in addition to, or with, this dilution operation, to a thorough impregnation with this liquid, for example inside an apparatus (3) for dilution and impregnation. The delivery of the mixture obtained is then carried out by means of a Vortex pump (6) capable of conveying a liquid-solid mixture and driven at a variable speed by means of a control device comprising a flow detector (6a) and arranged so as to keep constant the flow rate in the delivery pipe (10). <IMAGE>

Abstract: A reflective tunnel (2) of rectangular cross-section with opposing parallel or converging sides has a light diffuser (12) located at the output opening (2a) of the tunnel for integrating the light passing therethrough, and a densitometer (3) located near the input opening (2b) of the tunnel for measuring the composition of the light within the tunnel. A lamp (14) is positioned at the inner focal point (17i) of each of a plurality of dichroic elliptical reflectors (17L, 17R) supported at the input opening so that light emitted by each lamp is projected into the tunnel directly toward the light diffuser. The lamps are symmetrically disposed about the optical axis of the reflective tunnel and the reflector axes are intersect the tunnel axis at a point (50) located between the midpoint (M-M) of the tunnel and the output (P-P) of the tunnel. Compensating means (25) may be located in a plane defined by the outer focal points (170) of the elliptical reflectors to compensate for variations in the reflector/lamp alignment. The light source can provide high intensity light of uniform intensity over the aperture, which is particularly suitable for the exposure of colour photographic prints.

L'objet de l'invention est de creer un nouveau procede, par exemple pour le modelage des caracteristiques acoustiques des mecanismes de la voix humaine, c'est-a-dire de la production de la voix. On obtient une approximation de la fonction de transfert acoustique modelant le canal sonore en subdivisant celle-ci par des procedes mathematiques en fonctions de transfert partielles de structures spectrales plus simples, On obtient une approximation de chaque fonction de transfert partielle par des fonctions de transfert rationnelles. Ces fonctions sont materialisees separement au moyen de filtres electriques equivalents, qui ont ete interconnectes en parallele et/ou en serie de la maniere correspondante a la fonction de transfert acoustique qui doit etre modelee. Les modeles produits par le procede selon l'invention peuvent egalement etre utilises dans l'identification de la voix, en estimant les parametres d'un signal de voix et dans un appareil denomme Vocoder.
