摘要:
Structural members (80) having an intermediate web (81) and hollow tubular side flanges (83, 85) extending longitudinally of the web (81) are formed in a cold rolling operation such that one of the tubular side flanges (83) has an outside diameter of the opposite tubular side flange (85). The larger diameter side flange (85) has a longitudinally slotted aperture (87) to permit a composite structure (120) to be formed by nesting the smaller diameter flange (83) in the larger diameter flange (85) of an adjacent structural member (80). The composite structure (120) having a plurality of interconnected structural members (80) may be assembled as a closed or open structure.

Eléments profilés (80) possédant une âme intermédiaire (81) et des ailes tubulaires creuses (83, 85) s'étendant sur la longueur de l'âme (81), fabriqués par laminage à froid, afin que l'une des ailes tubulaires (83) comporte un diamètre extérieur correspondant au diamètre intérieur de l'aile opposée (85). L'aile à plus grand diamètre (85) comporte une fente d'ouverture longitudinale (87) permettant de réaliser une structure composite (120) en emboîtant l'aile à petit diamètre (83) dans l'aile à grand diamètre (85) d'un élément profilé contigu (80). On peut assembler la structure composite (120) possédant une pluralité d'éléments profilés interconnectés (80), en structure ouverte ou fermée.
摘要:
Wall construction, comprising a number of framework components (12, 12', 12'', 22), including uprights (12, 12', 12'') and horizontal beams, at a distance from each other, a number of wall components, including panels (15) and casings (28), and coupling means composed of a number of couplings each designed for coupling a wall component to a framework component, a wall component coupled to a framework component having an essentially vertically running straight edge along which one or more couplings are fitted. A coupling comprises a guide means (12, 17, 18, 34, 34') for the framework component, a sliding plate (1, 1', 1'', 20) which is slidable vertically over or in the guide means, and a hook element (6, 25, 27) fitted on a wall component with a lip (11) extending essentially vertically, in such a way that after placing of the wall component against the framework component the sliding plate is slid by means of a pushing end (13') of a tool (13) from an uncoupled position in a vertical direction along the adjacent edge of the wall component to a coupled position over the lip.
摘要:
A coupling device (10) and method of coupling especially suitable for coupling multiple components of surgical instruments are provided. A wedging portion (12) provides an interference fit between parts so that a secure connection can be made that will not unintentionally dissociate. In a preferred embodiment, bores (31,50) and counterbores (46,29) within dovetail portions are provided. Especially preferred is the use of this coupling device to secure a reamer head to a shaft.
摘要:
A rotary slot cutting tool having a flat sided disc shaped body with a central bore (21), a plurality of apertures spaced about the periphery of the body each aperture (16) having in it a cutting insert (11), held in position by the shape of the aperture against radial movement, each aperture being shaped in such a manner that on the application of a force (29) acting radially outwards on the circumference of the bore (21) of the body, faces (25 and 26) of the aperture are caused to spread apart to permit removal and replacement of the inserts (11) in an axial direction.

摘要:
Une paire de plaques (21) ayant chacune une protubérance (23) intérieurement filetée à sa base et des rebords relevés (22) sur ses côtés est fixée à la surface supérieure de segments adjacents (11, 12, 14) d'un ski en segments. Une paire de lèvres (31) formées sur un support glissant rigide (27) engagent lâchement des lèvres alignées (25) sur les rebords (22). Une pièce élastique d'épaisseur (28), est placée entre les lèvres (31) du support glissant (27) et celles des rebords (22). Une paire de vis (33) portées par le support glissant (27) et s'imbriquant dans les protubérances filetées (23) attachent le support glissant (27) aux plaques (21), en reliant rigidement les segments du ski (11, 12, 14).
摘要:
This invention concerns a hook for coat-hangers, equipped with a double-jointed supporting base, which allows the hook to rotate freely around both a vertical and a horizontal axis. The supporting base consists of a small plate with a superficial groove, shaped like an inverted "T", within which the base of the hook is inserted and remains fixed, permitting the base to rotate around its longitudinal axis. This grooved plate connects to an open ring which will hook onto the neck of the hanger, so that the rotation of the ring on the hanger allows the hook to collapse inside the hanger.
