Abstract: 1. Process for the preparation of 1,5-diacetyl-2,4-dioxo-hexahydro-1,3,5-triazine (DADHT) by acetylation of 2,4-dioxohexahydro-1,3,5-triazine (DHT), with acetic anhydride, characterized in that the DHT, suspended in acetic anhydride and/or mother liquor from the preparation of DADHT, is heated together with alkali metal hydroxide to a temperature of 90 to 150 degrees C (363 to 423 K) in a molar ratio of DHT to alkali metal hydroxide of 5 to 40 with simultaneous fractional distillation of the acetic acid forming during the acetylation, the head temperature of the distillation column being 97 to 118 degrees C (370 to 391 degrees K) at 65 to 101 kPa at a reflux ratio of 2 to 8 and the acetylation reaction being carried on until 70 to 100% of the amount of acetic acid to be expected theoretically has distilled off and the concentration of the acetic acid in the reaction mixture does not exceed 5 to 20 mass-%.

Granted: 1991-05-02
Abstract: Pour le fonctionnement d'engins de construction, il est souvent nécessaire de changer rapidement d'un outil de travail à un autre pour divers types de travail. De manière à obtenir un accouplement rapide, des potences ou une structure de support extensible d'adaptation sont ajoutées au bras de support et au mécanisme de liaison du véhicule pour monter un outil de travail d'une conception spécifique. De telles conceptions sont connues pour modifier la fonction des mécanismes d'assemblage à un point tel que le rendement de l'outil de travail est sacrifié sur le plan de la capacité et des possibilités de force opérationnelle. L'appareil d'accouplement (10) permet l'accouplement et le désaccouplement rapide d'une pluralité d'outils de travail (12) sur un véhicule ou engin. L'appareil d'accouplement (10) permet d'obtenir des résultats suivant une manière qui maintient la géométrie de fonctionnement des mécanismes de liaison conventionnels et par conséquent maintient les forces opérationnelles appropriées nécessaires à la manipulation de l'outil de travail (12) avec une très petite réduction de la capacité par rapport à celle d'un outil de travail conventionnel (12).

Title: Manufacturing method for a shaped body of sheet metal pieces with different thicknesses
IPC: B23K26/00
Filed: 1986-12-22
Granted: 1992-03-11
Abstract: A process for making a shaped member from sheet metal pieces (37,38) of different thicknesses. In the process flat sheet metal pieces (37,38) are butt welded at their cut edges by laser beam welding. Then the unit, welded together from a number of sheet metal pieces (37,38) of different thickness, are converted into a shaped member by pressing or deep drawing. Since the material of sheet metal pieces (37,38) is not much affected by laser beam welding and the laser-beam-welded joint (39) does not expand much, the joint (39) has no adverse effect on shaping, nor is any anti-corrosion protection, for example, of zinc lost during laser beam welding.
Patent EP-0206640-B1 (EP)
IPC: B21C37/20
Filed: 1986-06-11
Granted: 1989-02-01
Abstract: A heat transfer tube (10) has mechanical enhancements which improve the heat transfer properties of at least the outer (12) surface of the tube. An optional internal enhancement, which is useful on either boiling or condensing tubes, comprises a plurality of closely spaced helical ridges (16) which provide increased surface area and are positioned at an angle which gives them a tendency to swirl liquid flowing through the tube. The external enhancement, which is applicable to boiling tubes, is provided by successive cross-grooving and rolling operations performed after finning. The finning operation, in a preferred embodiment for nucleate boiling, produces fins while the cross-grooving and rolling operation deforms the tips of the fins and causes the surface of the tube to have the general appearance of a grid of generally rectangular flattened blocks (see Figure 8) which are wider than the fins and separated by narrow openings (20) between the fins and narrow grooves normal thereto. The roots of the fins and the cavities or channels formed therein under the flattened fin tips are of much greater width than the surface openings so that the vapour bubbles can travel outwardly through the cavity and to and through the narrow openings. The cavities and narrow openings and the grooves all cooperate as part of a flow and pumping system so that the vapour bubbles can readily be carried away from the tube and so that fresh liquid can circulate to the nucleation sites. The rolling operation is performed in a manner such that the cavities produced will be both larger and smaller than the optimum minimum pore size for nucleate boiling of a particular fluid under a particular set of operating conditions.

Granted: 1992-04-08
Abstract: In a multisectional storage container, especially a storage box for the storage of plate- or disk-shaped items, such as compact disks or diskettes, for example, it is proposed that individual storage sleeves be interconnected one with the other in an articulated manner by means of interconnecting means in such a manner that the sequence of sleeves can be opened in the nature of a parallelogram mechanism or in an accordian-like manner, thus enabling all of the items that are contained therein to immediately be visually inspected and identified and/or manually removed. By subsequently collapsing the individual storage sleeves of the storage box, it is possible to house them in a minimum of space, without any clearance one between the other, and, if desired, to store them in a dust-tight manner by means of an enveloping enclosure.

Abstract: Un système sensible à la charge est pourvu de deux systèmes de synchronisation pour la compensation des charges positives et négatives. L'un des systèmes de synchronisation fait varier l'écoulement traversant un compensateur de charge négative, durant la régulation d'une charge négative, en réponse à la pression d'admission d'un moteur hydraulique (10) qui est commandé par un compensateur de charge positive (51). L'autre système de synchronisation isole la pompe (12) du système du moteur hydraulique (10) durant la régulation de la charge négative, pendant qu'un écoulement d'appoint dirigé vers le moteur hydraulique (10) est fourni par le système (11a) d'échappement du fluide. Dans un mode de réalisation plus spécifique, la pompe (12) du système est isolée du moteur hydraulique (10) grâce à l'utilisation du compensateur de charge positive (51) et est totalement indépendante de toute action de compensation de charge négative. Les systèmes de synchronisation fonctionnent en réponse à un ou plusieurs signaux externes qui peuvent être fonction de n'importe quel paramètre spécifique choisi du système (SW, S2, S3, S4, S5).

Abstract: An improved thermal circuit breaker is disclosed, featuring a U-shaped bimetallic element which latches an escapement locking arm which holds a spring biased moving contact against a fixed contact when the breaker is in the contacts closed position. The improved thermal element has terminal portions which are of lesser electrical resistivity than are other portions of the element. The relative orientation of the metals of the bimetallic element in the terminal portions are reversed with respect to their orientation in the remainder of the bimetallic element. In this way ambient temperature compensation is provided to the breaker such that the current rating of a given breaker does not vary with variation in ambient temperature.

Abstract: An assembly for the preparation of ceramic composite structures includes a segmented container (12) within which a permeable filler is retained and a parent metal body (20) is contacted with the bed (18) of permeable filler. The segmented container (12) is comprised of one or more segments made of a material, such as an Inconel alloy, which has a coefficient of thermal expansion which is significantly greater than that of the filler. The segments are arranged to define between or among them one or more expansion joints which are effective to accommodate circumferential thermal expansion of the segments to thereby inhibit or prevent volumetric expansion of the container (12). A method of forming ceramic composite structures includes heating the resulting assembly to melt and oxidize the parent metal, (20), e.g., aluminum, to form a polycrystalline material comprising an oxidation reaction product which grows through the mass of filler to embed it and thus form the composite structure.
