Abstract: L'invention concerne un organe élastique (4, 14) et un procédé utilisé pour introduire celui-ci dans une conduite (3, 13) ayant une section transversale ouverte ou fermée. L'organe élastique (4, 14) introduit dans la conduite est amené à exercer une force perpendiculaire aux parois de la conduite (3, 13). Pour enlever l'organe élastique (4, 14) de la conduite (3, 13) en éliminant la force qu'il exerce sur les parois; une force de traction est longitudinalement exercée sur l'organe élastique (4, 14) en provoquant une tension accrue dans le sens longitudinal et une contraction dans la sens transversal, de sorte que la section transversale de l'organe élastique (4, 14) devienne plus petite que la section transversale de la conduite (3, 13). L'organe élastique (4, 14) peut ainsi être introduit dans la conduite (3, 13) ou en être retiré sans friction on peu friction avec les parois de la conduite (3, 13).

Abstract: The housing (1) of the wrist watch consists of a central part (2) and a base (3), which has an annular projection (13) on its inner surface, and is closed by the watch glass (4) at the top. A mechanism retaining ring (7), which is inserted into the housing (1) and supports the watch mechanism (8), consists of a plastic which is slightly resiliently yielding and has a downward-facing annular flange (11) which is clamped, with compression, between the annular projection (13) of the base (3) and the inner periphery of the central part (2), and so simultaneously connects the base (3) to the central part (2) in a leak tight manner as a pressure fit. The wrist watch can also be composed of the housing (1) and of an outer ring (5) supporting the bracelet connections (6), into which outer ring the housing (1) is detachably pushed from below. The axial fixing of the housing (1) in the outer ring (5) is provided by a resilient ring (20) which rests in an annular groove (21) provided on the outer periphery of the central part (2).

Abstract: The invention relates to a dental handpiece with a head housing (1) for receiving a tool (2) and a neck part (3) which extends essentially perpendicular to the axis of symmetry (5) of the head housing (1) and in which a light guide (6, 9) is arranged, whose end (6a, 9a) opens out on the neck part (3) adjacent to that end of the head housing (1) directed towards the tool, and ends there in such a way that the light beams are thrown essentially onto the tip (S) of the tool (2). In order to obtain, inter alia, an optimum adaptation of the end of the light guide to the contour of the handpiece, according to the invention the front face (7, 10) of the light guide end (6a, 9a) forms the optical boundary between incident and refracted light beams. The front face which, as it were, forms part of the circumferential surface (8) of the neck part (3) is in addition inclined in relation to a reference plane defined by the longitudinal axis (4) of the handpiece and the tool tip (S) in such a way that the emerging light beams are deflected towards this plane. <IMAGE>

Abstract: In the tongue bed having a base plate (1) and bearing rails (2,3) extending upwards from the base plate (1) a flexible movable point of two converging rails can be positioned either to the right or to the left from the inside against the bearing rails (2,3). Production by casting requires large machining allowances because of the demands for accuracy, and welding against the remaining rail section is problematic by virtue of the fact that complete removal of bubbles from the casting can only be achieved with difficulty. In the case of tongue beds of forged or rolled solid material, this difficulty is overcome; however, a large amount of material has to be cut away. The problem exists of producing a dimensionally accurate tongue bed possessing good metallurgical properties and with a large freedom in the selection of material, which can readily be connected with the adjoining rails and involves little expenditure in terms of labour. For this purpose, the bearing rails (2,3) are welded at the foot with the base plate (4 to 7). In spite of the possibility of achieving high strengths of above 800 N/qmm, the machining work is small, and a good structure can be achieved by means of a deforming pre-treatment, forging or rolling. <IMAGE>
