摘要:
The present invention relates to a device for controlling a brake (11) of a wheeled walking frame (10) provided with a handle (12), including a control device (25) movably connected to the brake (11) via a connector (24) for controlling the braking effect using hand power, the control device (25) being displaceable between an idle position without braking effect and at least one braking position for braking effect. The control device (25) is movably connected to a cover (23) of the handle (12), which cover (23) is designed for receiving and partially encasing the control device (25), the control device (25) being, in the idle position, at least partially retracted into the cover (23) so that the cover (23) and the control device (25) form the handle (25). Furthermore, the control device (25) is displaceable from the idle position further into the cover (23) to the braking position while effecting the connector (24). The present invention also relates to a method for controlling a brake (11) of a wheeled walking frame (10) provided with a handle (12).

摘要:
A sealing device for sealing a space established by connecting two sealing surfaces (42b, 52b) positioned on one element each of two elements (44b, 48b), for example two concrete pipes, to a position in which the sealing surfaces face each other comprises a sealing body (80) consisting of elastic material. The sealing body (80) is adapted at the connection of the sealing surfaces (42b, 52b) to take a position in the space in which it engages the sealing surfaces. The sealing device comprises an activating device (82-90) for forcing the sealing body (80) positioned in the space against the sealing surfaces (42b, 52b) when the activating device is activated.

摘要:
A sealing device for a sealing space defined by sealing surfaces of two elements (2, 6), preferably pipes or well rings consisting of concrete, comprises a sealing element (28). The sealing element is adapted to seal a section of the sealing space extending transversely of the jointing direction of the two elements and has prior to the jointing of the elements a substantially C-shaped cross section.

The present invention relates to a method for the manufacture of a matrix and to a matrix (1) thus manufactured, at least one surface section (2) displaying a microstructure, which matrix (3) is suitable for inclusion as a mould insert in a mould cavity or in a cavity, in a unit producing plastic components, in order to assign said plastic components an opposing micostructure in a corresponding surface section. An original (3) with a surface section (4) displaying a microstructure less than 500 &mgr;m is used in order to apply on this original layer upon layer of a material (11, 12, 13, 14) and/or mixtures of material producing a matrix, and thereafter the matrix (1) is removed from said original (3) or the material in the original is removed. A first layer of material (11) applied on the original (3) so that together with a number of additional layers of material, said matrix is formed, is selected having exceptionally good properties as regards the ability of the plastic component to release from the matrix after moulding, curing or polymerisation of the plastic material used, and exceptionally good properties as regards retaining the pattern on the microstructured surface section.
摘要:
A method and apparatus are described for very low pressure high powered magnetron sputtering of a coating onto a substrate. By the method of this invention, both substrate and coating target material are placed into an evacuable chamber, and the chamber pumped to vacuum. Thereafter a series of high impulse voltage pulses are applied to the target. Nearly simultaneously with each pulse, in one embodiment, a small cathodic arc source of the same material as the target is pulsed, triggering a plasma plume proximate to the surface of the target to thereby initiate the magnetron sputtering process. In another embodiment the plasma plume is generated using a pulsed laser aimed to strike an ablation target material positioned near the magnetron target surface.

The present invention relates to a coated cutting insert with excellent toughness properties particularly useful for toughness demanding short hole drilling in general steel materials and a method of making the same. The inserts comprise a substrate and a coating. The substrate comprises WC, from about 8 to about 11 wt-% Co and from about 0.2 to about 0.5 wt-% Cr with an average WC-grain size of from about 0.5 to about 1.5 μm and a CW-ratio of from about 0.80 to about 0.90. The coating comprises a first (innermost) layer of TiCxNyOz with a thickness less than about 1.5 μm, a layer of TiCxNyOz with a thickness of from about 1 to about 8 μm with columnar grains, a layer of fine-grained grain κ-Al2O3 with a thickness of from about 0.5 to about 5 μm and a further layer less than about 1 μm thick of TiCxNyOz whereby at the rake face the outermost TiCxNyOz-layer and Al2O3-layer are fully or partly missing.

摘要:
A pipe joint comprising two sealing surfaces (6, 36) one positioned on each of two end portions (2, 4) of two pipes and a sealing device comprising a sealing ring (18). The sealing surfaces (6, 36) form a cylindrical sealing space in which the sealing ring (18) is compressed. In connection with the sealing ring there is in one of the pipe end portions arranged a circumferential cavity (34) partially receiving the elastic material of the sealing ring (18). The sealing surfaces (6, 36) form sealing space portions having a small and substantially equal space width on either side of the sealing ring (18) in the axial direction of the joint for forming supports for carrying transverse loads on either side of the sealing ring.
