摘要:
A capsule containing at least one component of a lubricant for a machine element, whereby the capsule comprises an external wall including a first substance that is arranged to perish during the use of the machine element when the capsule is placed in and/or around the machine element and/or into lubricant being used to lubricate the machine element.

A fastener and a method for reducing wear on a driver blade in a fastening tool includes applying a layer of solid-based lubricant between the head of a fastener and a driver blade end. The fastener is for use in a fastening tool and includes a head, a shank, and a layer of lubricant on the head of the fastener. The lubricant is graphite, molybdenum disulfide, tungsten disulfide, boron nitride, polytetrafluoroethylene (PTFE), nano-diamonds, calcium stearate, sodium stearate, oils, greases, waxes, thermoplastic polymers, or another lubricant that exhibits similar characteristics. Aromatic polyamides (such as Kevlar™), ultra-high molecular weight polyethylene, powdered glass, glass fibers, thermoplastic polymers, and thermoset polymers also are contemplate to provide a barrier to contact between the driver blade and fastener head. The lubricant is sprayed, rolled, brushed, blotted or otherwise applied between the head of the fastener and the driver blade end prior to firing the fastening tool.
摘要:
The present invention relates to a method and arrangement for controlling exposure in an e-ray apparatus, for depicting an object. The apparatus comprises an x-ray source and a displaceable detector being arranged to move with a controllable speed across an image exposure area. The method comprises the step of: acquiring a signal relating to photons incident on at least a part of the detector, comparing said acquired signal with a target value, and controlling the speed of detector, displacement with respect to the result of the comparison.

The invention relates to a framed art hanging system for hanging pictures and other similar items such as art, photos, diplomas, posters, paintings and framed sports memorabilia on walls. The system allows the installer of a framed picture to easily hang the picture utilizing the combination of a magnetic connection and a mechanical connection. The magnetic connection is achieved by utilizing a magnet, preferably adhered to a plate which is attached to either the back of the picture frame or to the wall and a metal plate which is magnetically attracted to the magnet, the metal plate being placed on the other location (either the back of the picture frame or to the wall). Three example ways to achieve a mechanical connection are described. The first way is to place an abrasive coating on either the frame plate or the magnet plate and a deformable substance coating on the other. The second way is to combine fins and grooves, one being placed on the frame plate and the other being placed on the magnet plate. The last way is to utilize geometric protrusions and depressions, one being placed on the frame plate and the other being placed on the magnet plate.
摘要:
A system for re-lubricating a machine element, which comprises an analysis device arranged to determine which part of a lubricant that is being used to lubricate the machine element has been depleted and to generate a signal indicative thereof. A lubrication element is arranged to automatically re-lubricate the machine element only with the part of the lubricant that has been depleted in response to the signal.
摘要:
A coated fastener has a tip and a coating on the fastener, at least at the tip. The coating is formulated from a solvent-borne resin. The fastener includes one or both of a solids based additive in the solvent-borne acrylic resin and an overcoat on the solvent-borne acrylic resin. A strip of collated fasteners with the coating is also disclosed.
