Abstract: Recipient thermiquement isole pour la cuisson, le service et l'emmagasinage d'aliments et de boissons, particulierement destines a etre utilises dans des unites de cuisson aux micro-ondes. Un recipient a double paroi, comprend un chemisage externe (1) et une doublure detachable interne (2), les deux ayant des formes sensiblement similaires. La doublure est supportee par une collerette rainuree (4) s'etendant vers l'exterieur depuis son bord superieur qui repose sur le bord superieur du recipient externe. Les parois interne et externe sont separees par un espace etroit (3) formant une cavite d'air enfermee. La rainure de collerette (7) et le bord sont destines a permettre a l'air de s'echapper de la cavite afin de limiter la pression engendree par les nourritures ou boissons chaudes du recipient et d'empecher l'air de penetrer dans la cavite pendant que le recipient se refroidit. Un couvercle sureleve (9) est egalement prevu et s'ajuste sur le recipient de doublure interne, et presente une partie superieure plate et une poignee dans un renfoncement (12) afin de permettre a plusieurs recipients d'etre empiles les uns sur les autres pour la cuisson et le stockage.

Abstract: Methode de connexion des extremites d'une bobine a induit par un procede de soudage ultrasonique sur une pluralite de segments disposes sur la peripherie d'un arbre et moules integralement sur un commutateur. Pour effectuer la soudure aux ultrasons des extremites de la bobine de l'induit, on fait vibrer les extremites suivant une direction qui rend la composante axiale de la force de vibration le long de l'arbre inferieure a la force de liaison du materiau de moulage sur les segments, de maniere a connecter la bobine de l'induit sur les segments. Cette methode est adaptee pour connecter un enroulement d'induit d'une machine electrique rotative, telle qu'un demarreur, sur son commutateur.

IPC: E01C19/10

Abstract: The prior art discloses drum mixer developments which virtually uniformly strive for the criterion of a cross-sectionally uniform distribution of the aggregates/asphalt mixture in discharge cascades, sliding off lifting paddles, over the drum cross-section. It is shown that a uniform distribution of the mixture over the drum cross-section is not possible and that the formation of discharge cascades severely impairs the aim generally sought with drum mixing of achieving a low-dust preparation by partial distribution of the material in discharge cascades. As a result, a method is proposed which permits the preparation of asphalt-aggregate compositions in a drum mixer while avoiding any notable dust formation and providing optimum thermal efficiency. The solution provides that, during its passage, the material be raised in a constantly repetitive manner along the inner wall of the rising drum until the frictional forces are overcome by the force of gravity, and guided back again to the bottom of the drum. The material travels as a circulating mass through the drum, which mass describes a segment of a circle deformed at the edges in its cross-section, and absorbs radiant heat across its surface and convected heat via the drum wall. An improvement in the mixing intensity and the heat absorption is achieved, with constant drum diameter, by enlarging the heat-transferring inner surface, in conjunction with a positive material guide, which is slidingly inclined to the bottom of the drum and is preferably sill-shaped, and at the same time the mixing intensity is promoted. This guide is preferably supported by mixing tools (2/3) of wedge-shaped design inclined relative to the rising drum (1), these tools being assigned radial rods (4) as required. <IMAGE>

Abstract: The invention relates to a curable adhesive based on a reactive acrylate and/or methacrylate copolymer. The reaction principle, on which the curing of the adhesive is based, is the reaction of the hydroxyl groups of the  omega -hydroxyalkyl esters of acrylic and/or methacrylic acids with the isocyanate groups of the polyisocyanates or their partial reaction products with polyols. The inventive adhesives can be used without solvents or with only a slight content of organic solvents. They adhere well to plastic and metal surfaces, even when exposed to the effects of water or water vapor. The best values for the drum peel strength are obtained from acrylic copolymers whose molecular weight falls in the range of 1,000 to 3,000.

Abstract: The present invention provides a rapidly-soluble sweetener, a process for preparing it, and improved dry beverage mixes employing it. 
     The composition preferably comprises from 15 to 65% fructose, from 15 to 30% of low dextrose equivalence dextrinized starch, and from 30 to 65% sucrose, on a dry solids basis. By preparing it with a density of 0.4 or less, solubility is greatly enhanced over prior art sweeteners, especially sucrose. 
     Because of the improved solubility, carbonation is not lost by requiring stirring of a sweetener when preparing a beverage from a dry carbonated beverage mix.
