Abstract: Les petits appareils décrits sont actionnés électriquement au moyen de systèmes de commande pneumatique à distance (Fig. 1) qui passent et fonctionnent par le câble de connexion (Fig. 2). Leurs commutateurs électriques ne sont pas incorporés dans les appareils mais placés extérieurement et combinés à l'intérieur de l'unité à fiches de connexion (Fig. 3). Ainsi, même si ces appareils sont branchés dans la prise, le circuit ne peut atteindre les éléments de mise sous tension qui sont incorporés dans l'appareil que lorsqu'on le désire et uniquement lorsqu'on presse les boutons de mise sous tension. C'est pourquoi aussi, grâce à ces caractéristiques, ces appareils permettent d'éviter que des accidents ne se produisent au détriment de personnes ou de choses, au cas où ils tombent accidentellement des mains de l'utilisateur durant leur fonctionnement.

Abstract: Anchoring bar (1), provided with a shaft (2) with several conical sections (7), cemented by means of a hydraulic mortar (12) in a borehole (11) made in a fixing foundation (10). When a crack appears, causing an increase in the diameter of the borehole (11), the mortar case expands, under the tractive force applied to the anchoring bar (1), as a result of a slippage of the anchoring bar (1) in relation to the hydraulic mortar (12). The outer surfaces of the conical sections (7) are therefore designed to be low in friction, provided with, for example, a coating, a film or a casing.

Inventor: BERNSEN JOHANNES ARNOLDUS CORN
IPC: G06T1/00
Filed: 1989-08-22
Abstract: The invention relates to a method of recognizing a pattern in a field having a multi-valent amplitude, using association with a reference mask which is composed of logic high units and logic low units, and also relates to a device for performing such a method. The reference mask is sub-divided into two sub-masks, units having the same logic value belonging to the same sub-mask. The first and the second sub-mask contain relevant logic high units and logic low units, respectively. After the positioning of the sub-masks in the field, a relatively lowest and a relatively highest value of the amplitude are determined within the window of the first and the second sub-mask, respectively. When the difference formed by the relatively lowest value minus the relatively highest value is not negative, the desired pattern can in principle be recognized in the field. 
     A device in accordance with the invention comprises at least one rank-value filter for determining the relatively highest value and the relatively lowest value. 
     The conventional thresholding of the field, followed by comparison with a binary reference mask is replaced in accordance with the invention by the determination of the sign of the difference between the relatively lowest value and the relatively highest value of the amplitude.
