Abstract: In the case of the adjustable upper link in a three-point suspension device for a tractor, comprising a locking device in the form of a line fitted with a shut-off device and connecting together the two end-faces of the hydraulic cylinder, the invention simplifies the operation of the device in that it may be adjusted effortlessly from the tractor-seat. This is achieved in that the shut-off device is in the form of a ball-valve having an axis secured to a forked actuating lever, and in that springs are provided to urge the said actuating lever towards the shut-off position. A scale provides the tractor-driver with an accurate indication of the setting of the link. The design of a tube accommodating one end of the piston-rod as a compressed-air chamber ensures automatic displacement of the piston in the hydraulic cylinder.

Abstract: The catheter consists of a metal cannula (4) which has at its front end a sharp edge (7) and at its rear end a gripping piece (5). The metal cannula (4) is inserted into a capillary tube (1) from whose front end the end of the metal cannula (4) protrudes. In order to ensure that the projection of the metal cannula (4) at the front end of the capillary tube (1) assumes a defined value, the gripping piece (5) connected to the metal cannula (4) can be displaced in the longitudinal direction relative to the gripping piece (2) connected to the capillary tube (1). This displaceability is achieved, for example, by means of a tapered ring (12) which can adopt different rotational positions and is fixed after its adjustment. <IMAGE>

Abstract: An infrared shielding lamination comprises alternate infrared shield layers and interferential reflection layers. These layers have good transparency to visible light and the infrared shield layers are able to prevent the transmission of the infrared rays. The interferential reflection layers along with adjacent infrared shield layers cause an interferential reflection effect on the wavelengths in the near-infrared spectrum, thus preventing the transmission of near-infrared rays. When a composite lamination according to this invention is applied to a glass plate or other plate transparent to visible light, the so-treated plate will exclude infrared and near-infrared rays without impairing the transparency of the plate to visible light.

Abstract: ® A mask sheet (8) which has a pattern of elongate apertures (10) is deep-drawn by means of a bilateral drawing process in which the edge (9) is bent over along the folding line (21). In the corner of the skirt (23) a pattern of pits (24) is provided the longitudinal direction of which is parallel to the diagonal (25) of the mask sheet (8). As a result of the pits (24) the skirt (23) is weaker in a direction at right angles to the diagonal (25) than in a direction parallel to the diagonal (25). The pits (24) compensate the buckle load occurring in the bilateral drawing process and are deformed at right angles to the longitudinal direction. As a result of this the formation of pleats in the corners of the mask sheet (8) is prevented.
