Patent EP-0623575-A1 (EP)
Inventor: BRAUN MAX DR
IPC: C07C49/167
Filed: 1994-04-19
Abstract: Described is a novel process for the preparation of ketones, for example CF3C(O)CH3, CF3C(O)CH2C(O)CF3 and CF3C(O)CF2H. In this process, ss-keto esters are transesterified and decarboxylated with a carboxylic acid, for example trifluoroacetic acid, in the presence of a catalyst, in particular an "onium" salt of a carboxylic acid or an effective amount of a proton-liberating acid, preferably a sulphonic acid such as alkyl- or arylsulphonic acids, or a mineral acid. It is expedient to carry out the process under anhydrous conditions. Therefore, no acetals or hydrates are formed, so that a dehydration step can be dispensed with. A further advantage of the process is the simple procedure. If a sufficiently active carboxylic acid is used for the transesterification reaction, for example trifluoroacetic acid, the presence of an additional catalyst is not required.

Abstract: The invention relates to a device (10) for controllable greasing of workpieces (11) in strip or blank form with a plurality of hollow greasing rollers (12-16) which are provided with a material permeable to grease, are aligned coaxially to one another, are each rotatably supported on a hollow shaft (17) and can be driven by a belt drive (18) which is connected to a motor (23) by a drive shaft (19, 20) mounted in a housing or a frame (21). In this arrangement, the greasing rollers (12-16) can be placed against the surface (11a, 11b) of the workpiece by means of actuating cylinders (20). The object on which the invention is based is to provide a device of the type stated at the outset in which the belt drives for driving the greasing rollers are distinguished by a constant belt tension, irrespective of the operating position of the rollers. This object is achieved, according to the invention, by virtue of the fact that the hollow shaft (17) is pivotably mounted on the drive shaft (19, 20) by way of a lever (28) and that the pivoting movement of this lever (28) can be performed by an actuating cylinder (20). <IMAGE>

Abstract: When carrying out multi-spot welding, the electric welding circuits (3.1 ... 3.16) are activated in such a way that successive welding intervals (I1 and I2 or I2 and I3 ..., respectively) partly overlap, i.e. by more than 0% and less than 100%. This permits a graduation with reduced maximum power input when welding wire grids and the like. Excessive deformation of the cross-wire (1) to be welded in the case of narrow-mesh wire grids can thus be avoided. <IMAGE>

Abstract: Un système de commande de processus comprend au moins une variable manipulée et au moins une variable commandée et permet d'effectuer une commande robuste d'un processus. Des contraintes prédéterminées des variables manipulées et des variables commandées, et les valeurs actuelles des variables manipulées sont obtenues. De nouvelles valeurs sont calculées pour les variables commandées pour un nombre prédéterminé de points dans le futur, de sorte que les valeurs des variables commandées se trouvent dans la plage prédéterminée, ce qui permet d'obtenir une robustesse optimale du contrôleur résultant. Les variables manipulées sont également calculées pour se trouver à l'intérieur des contraintes prédéterminées, et les variables commandées tombent dans une plage prédéterminée lorsqu'elles peuvent être commandées. A partir de plusieurs solutions, la solution la plus valable est choisie. Ensuite, les variables manipulées sont ajustées afin que le système de commande du processus fasse correspondre les valeurs des variables commandées aux valeurs calculées.

Title: Joints with gaps
Inventor: LINZELL GEOFFREY ROBERT BROOKM
IPC: B23K35/02
Filed: 1994-04-25
Abstract: In the Specification of our International Patent Application PCT/GB 91/00950 there is described and claimed a method of securing against lateral motion two bodies held in face to face asperity contact, thereby to make a join between the two bodies, in which methods there is inserted into the interface between the two bodies a material that on minimal initial lateral relative motion of the two surfaces promotes rapid but controllable "galling" between the two surfaces, this galling binding the surfaces against further such motion. However, this method requires the two surfaces to fit well one to the other, and without such a good fit the resultant join may not be entirely satisfactory. The present invention's proposed solution to this gap problem is to use a metal-particle-containing composition comprising the gall enhancing agent loaded with a myriad of small metal particles, which composition can be packed into the gap, and will flow to accommodate a wide range of gap sizes and also to accommodate out-of-round distortion. The composition can take various physical forms, typically those of a free-flowing powder, a viscous liquid, or a stiff paste (and the powders have an additional use in the preparation of preforms for the manufacture of sintered parts).

Abstract: L'invention concerne un procédé de déparaffinage au solvant d'une charge d'huile paraffineuse en vue d'obtenir un produit de lubrification à base d'huile de pétrole, ce procédé consistant à mettre en contact, par contre-courant, une charge d'huile paraffineuse chaude (101) avec une membrane perméable sélective afin de transférer sélectivement le solvant froid à partir d'un courant froid (110) de filtrat huile/solvant traversant la membrane vers la charge d'huile paraffineuse chaude. Le transfert du solvant froid vers la charge d'huile paraffineuse chaude refroidit simultanément la charge d'huile paraffineuse chaude, dilue la charge d'huile paraffineuse chaude avec un solvant et sépare le solvant du courant froid du filtrat huile/solvant. La charge d'huile paraffineuse, après refroidissement et dilution (102), est ensuite refroidie par un premier échange thermique indirect avec un filtrat froid (109) puis avec un réfrigérant, afin de cristalliser et de précipiter la cire dans la charge d'huile et d'obtenir un mélange huile/solvant/cire. Le mélange huile/solvant/cire est ensuite dilué avec un solvant froid (104) afin d'ajuster la viscosité du mélange, puis le mélange est amené dans un filtre (11) qui filtre et retire la cire du mélange froid huile/solvant/cire. Un gâteau de cire froide (102) est récupéré ainsi qu'un courant froid de filtrat huile/solvant (108).
