Patent CA-2221885-A1 (CA)
Inventor: SHRIVE NIGEL G
IPC: E04C5/12
Filed: 1997-11-21
Abstract: An anchorage for a tendon that includes a sleeve having a smooth tapered interior bore and a compressible wedge disposed in the sleeve. The compressible wedge has a smooth exterior tapered surface tapering from a wider end to a narrower end and one or more interior channels for receiving a tendon. The taper angle of the compressible wedge is greater than the taper angle of the bore. Thus, upon insertion of the compressible wedge into the sleeve, the wider end of the compressible wedge forms a wedge contact with the sleeve before the narrower end forms a wedge contact with the sleeve. Preferably, the bore and wedge are conical,  and the wedge is formed of several symmetrical pie shaped resilient sections. Corners of the sections abutting at the interior channel are rounded. An inner sleeve is disposed in the interior channel, with the outer diameter of the inner sleeve matching the diameter of the interior channel.  The tendon is held by the inner sleeve.  A  pre-stressed  structure  may  be  formed  by anchorages at each end of a structure with a tendon in tension between them.

Patent CA-2233329-A1 (CA)
Title: Method for electrolytic deposition of metal coatings
Inventor: MEYER HEINRICH
IPC: C25D5/18
Filed: 1996-11-21
Abstract: The invention relates to a process for the electrolytic deposition of metal layers, in particular copper layers, of specific physico-mechanical and optical characteristics and of even thickness. With known processes using dissolving anodes and direct current, only an uneven metal layer distribution can be achieved on articles of complex shape.  The problem of uneven layer thickness at different points on article surfaces can be alleviated by using a pulsed current or pulsed voltage process, but this does not solve the other problem of continually changing geometry during deposition as the anodes dissolve. This problem can be eliminated by using non-dissolving anodes. To ensure adequate anode stability and a high lustre of the layers even at points on the workpiece surface where the metal is deposited with high current density, compounds of an electrochemically reversible redox system must be added to the deposition solution.

Title: Screw tip with means for closing a temperature control channel
Inventor: NIKOLAUS STEFAN
IPC: B29C48/84
Filed: 1998-02-26
Abstract: The invention relates to an extruder screw with an interior temperature control channel leading to the front end of said extruder screw, for carrying free-flowing temperature control media to and from the extruder screw. Said extruder screw also has a screw tip which shuts off the temperature control channel, said temperature control channel being open towards the front. This screw tip is screwed to the front end of the extruder screw, at least one seal being positioned between the two. The aim of the invention is to increase the effectiveness of the seal positioned between the screw part and the screw tip, without complex and expensive measures for precision fitting. To this end, the temperature control channel (12) which is open towards the front, at the front end of the extruder screw (11) is shut off by means of a closing screw (13), an axial seal (16) being positioned in-between. Said closing screw (13) has shaped recesses for engaging the screwing tools in such a way that they interlock, and has an outer thread (18) onto which the screw tip (17) is screwed.

Abstract: A needle protector having a body, a needle hub and a needle. The body includes a first end and a second end. The body consists of a hollow elongated cylinder defined by a continuous wall having a channel extending between the first and second ends. The continuous wall defines a recess adjacent the first end. The needle hub is movably mounted on the body.

Title: Plasma cvd system with an array of microwave plasma electrodes and plasma cvd process
Inventor: WALTHER MARTEN
IPC: C23C16/52
Filed: 1997-08-23
Abstract: The invention concerns a plasma CVD system (in particular a plasma pulse CVD  system) with an array of microwave plasma electrodes (2a, b, c, d). According to the invention, in order to improve the homogeneity of the layer, interference is prevented by controlling adjacent plasma electrodes (2a, 2b;  2b, 2c; 2c, 2d) in a chronologically offset manner. To that end, micropulses (A, B) are provided within the macropulses of the plasma pulse CVD process.  Additionally, the uniformity of the layer deposition at the interfaces between adjacent modules can be optimized by radio-frequency excitation by means of suitable electrodes (6, 62a-c), magnetic fields or the configuration of the gas inlets (5). The surface coated in an operating cycle can thus be scaled as required.
