Patent EP-0421082-A1 (EP)
Inventor: SPEIL WALTER DIPL-ING
IPC: F16H7/08
Filed: 1990-08-04
Abstract: The invention relates to a tensioning device for belts, chains and the like, especially for toothed belts in the valve gear of an internal combustion engine, having a support (1) which can be fixed on the engine block and on which, firstly, a lever carrying a pressure roller is pivotably mounted, on which, secondly, a tensioning element (16) which presses by means of a piston (15) on the lever is arranged, and on which, thirdly, a stop member is arranged which can be adjusted parallel to its longitudinal axis (21) from an assembly position into an operating position, in the assembly position blocks the stroke (25) of the piston (15) in an intermediate position by means of a stop face (22) and, in the operating position, releases the stroke (25) of the piston (15). It is the object of the invention to configure a tensioning device of this kind in such a way that the two positions of the stop face (22) in the assembly position and in the operating position are structurally predetermined and do not depend on a manual adjustment of the stop member. This object is achieved by the fact that the stop face (22) is formed by a side face of the stop member which extends parallel to the longitudinal axis (21) of the latter. In this way, manual adjustment of the stop member between the two positions is avoided and incorrect settings of the tensioning device are thus excluded. …<IMAGE>…

IPC: G01N27/72

Abstract: The test uses the incremental permeability method. Eddy currents are induced in the product to be tested (10) by creating periodic variations in the intensity of an external magnetic field applied to the product. This makes it possible to formulate the incremental permeability function expressing the relationship between a signal representing the detected eddy currents and the intensity of the magnetic field. The values of the intensity of the magnetic field (I) corresponding to an extreme value of the derivative of the incremental permeability function are determined for at least two different frequencies of the eddy currents defined as follows: &cirf& at least one first frequency, chosen between a high frequency (fH) for which the eddy currents are located mainly near the surface of the product in a region where the product normally has a first structure, and a low frequency (fB) for which the eddy currents reach a relatively deep region where the product normally has a second structure different from the first, and &cirf& a second, or critical, frequency (fC) predetermined in accordance with a chosen critical value of the depth of the transition between the first and second structures. Qualitative information about the tested product is generated, information which depends on the value of the intensity value determined for the critical frequency compared with the single value, or with each value, of the intensity value determined for at least one of the high and low frequencies. Application in testing the decarburization of steel products. <IMAGE>

Abstract: Les scarificateurs à impact sont utiles, par example, pour casser de la pierre et tout autre matériau dur que l'on ne peut excaver. Les systèmes que l'on connaît utilisent des structures qui proposent le montage du marteau d'impact et du pilon linéaire à l'intérieur d'un boîtier unique, ce qui transmet les vibrations dans le cadre de montage, posant ainsi des problèmes au niveau de l'utilisation et des coûts d'entretien. L'appareil scarificateur à impact linéaire présenté ici (10) possède un marteau d'impact (20) dont une extrémité est montée de manière résiliente sur un cadre de montage (14) et dont l'autre extrémité (104) est montée de manière à coulisser sur un des pilons linéaires (18) et sur le porte-outil (16). Par conséquent, l'appareil scarificateur à impact linéaire (10) présenté, réduit les vibrations transmises au cadre de montage (14) et possède des éléments distincts qui facilitent l'utilisation de l'appareil et qui réduisent le coût de l'entretien de celui-ci et qui, de plus, maintiennent l'alignement entre les pièces distinctes de la structure. Le système permet de connecter le marteau d'impact (20) à un des pilons linéaires (18) et de rendre le porte-outil étanche à l'atmosphère.
