摘要:
The present invention concerns a method of producing powder-metallurgical compacted components, which during subsequent processing are split into individual parts mating in pairs, sintered and optionally heat-treated and remated. According to the process, an iron-based powder is compacted, the obtained green body is fracture-split into at least two parts, which are subsequently sintered and optionally heat-treated. The obtained sintered parts are then remated.

A lubricant for metallurgical powder compositions contains an oligomer of amide type, which has a weight-average molecular weight M.sub.w of 30,000 at the most. A metal-powder composition containing the lubricant, as well as a method for making sintered products by using the lubricant, are also disclosed. Further, the use of the lubricant in warm compaction is described.

A polypeptide isolated from S. pyogenes is described, having IgG cysteine protease activity. The protease is designated IdeS, Immunoglobulin G-degrading enzyme of S. pyogenes. A polypeptide comprises SEQ ID NO: 1 and variants and fragments thereof having IgG cysteine protease activity or the ability to generate an immune response against S. pyogenes in an individual. Polynucleotides encoding these polypeptides and the polypeptides may be used in generating an immune response in an individual. IdeS protease inhibitors may be used in the treatment of S. pyogenes infection.

摘要:
To interrupt the current to the drive motor (3) of a motor-driven arm (1) which carries a pipette (2) when something or someone unintentionally contacts the pipette (2) during its movement, the arm 1) has a lower, rigid part (5), and an upper, flexible part (6) which, at its one end, carries the pipette (2) and, at its other end, is rigidly connected to the lower arm part (5). The upper, flexible part (6) is in releasable contact with the lower, rigid part (5) at the end that carries the pipette (2), and is adapted to, at least partially, the released from that contact when something or someone unintentionally contacts the pipette (2) during its movement. A detecting means (9) is adapted to detect when the upper, flexible part (6), at least partially, is released from the contact with the lower, rigid part (5) and in response hereto cause a switch to brake the current to the drive motor (3) for the arm (1).
摘要:
A welding device for powder welding is described, which comprises a welding head for transportation of at least one welding electrode to a welding area, and a powder transportation device for transportation of powder from a container to the welding area. The powder transportation device comprises at least a first pipe which at a first end has an opening which is arranged to be placed in the container in order to transport fluxing agent from the container. The powder transportation device comprises at least a first ejector which is connected to the second end of the first pipe and which is arranged to transport powder from the container via the first pipe using pressurized gas.
摘要:
A mobile terminal receives trustworthiness information for a software application by receiving a voucher that indicates the trustworthiness of that application as represented by a third party. To ensure the integrity of this information, the mobile terminal authenticates the voucher and verifies that the software application is the one having its trustworthiness indicated by the voucher. Given such indications of trustworthiness, a user of the mobile terminal may decide whether install and run it. If decided in the affirmative, the user may form his or her own basis for the trustworthiness of the software application. Accordingly, the mobile terminal may also create a new voucher that indicates the trustworthiness of the software application as represented by the user. With third parties representing the trustworthiness of software applications in this manner, their development is not hindered by the imposition of security requirements on application developers.

摘要:
A portable apparatus (1) for milking of animals (11-16) which are permitted to go loose is described. The apparatus (1) comprises a plurality of stalls (2) with at least one local milk tank (4) in each stall. The apparatus (1) comprises at least two separate lines (19, 20) arranged to receive the milk from the local milk tanks (4) in dependence of the quality of the milk.
摘要:
An iron-based powder for producing highly resistant components with a small local variation in dimensional change, by powder compacting and sintering. The powder contains, in addition to Fe, 0.5-4.5% by weight Ni, 0.65-2.25% by weight Mo and 0.35-0.65% by weight C, and optionally a lubricant and impurities. The maximum variation in dimensional change is 0.07% for a minimum density of 6.7 g/cm.sup.3.
摘要:
A radio transceiver included in or attached to an imaging camera is used to facilitate the automatic determination of a scale factor in a three-dimensional (3D) reconstruction. The radio transceiver transmits a radio signal from each of one or more camera positions and measures a reflection profile for the transmitted signal. The measured reflection profile is compared to a simulated reflection profile, generated from a 3D model of the subject/scene of interest, to determine an estimate of an unknown scale for the 3D model. In various embodiments, the radio transceiver may be adapted from a radio device that already exists in or on the imaging camera (e.g., a cellular radio, Bluetooth® radio, or the like) or may be added to an imaging camera.
