A method for joining two substantially planar fiber-composite structural components, includes stacking the two components on a support jig to overlap along a joining region. A lower component end section within the joining region borders a gap between the upper component and the jig, where the upper component is unsupported by the jig. The gap is bordered on an opposite side of the lower component end section by a filling portion of the upper component or a planar filler element supported by the jig. The lower component is joined to the upper component within the joining region by applying temperature and pressure to the components. A width of the gap allows the upper component to elastically deform along the gap under the pressure and bend down into the gap to abut the jig along the gap and thereby compensate thickness tolerances between the components during the pressure application.

An explosion-proof housing includes at least one metal housing part having at least one of a housing opening or receiving surface, and a support edge bordering said at least one of a housing opening or receiving surface. A cover part covers said at least one of a housing opening or the receiving surface. The cover part includes a peripheral cover edge which is connected to the support edge in an explosion-proof manner such that in the event of an explosion inside the housing, the explosion is prevented from crossing over to an explosive atmosphere surrounding the housing. A plurality of connection points are formed between the support edge and the cover edge. The connection points include interlocking depressions and protrusions. The protrusions are formed by partial melting of the cover edge. The depressions and the protrusions interlock with play in a longitudinal direction of the housing.

A blister pack includes a housing having a plurality of cavities and a cover sealed to the housing and enclosing the cavities. The cover including a base layer, at least one security element, and a heat protective layer. The heat protective layer includes one of an amorphous polymer and a semi-crystalline polymer.

The present disclosure relates to an apparatus used in the production of a sterilizing filter for dead-end filtration of medical liquids which comprises a plurality of microporous hollow fiber membranes having a large inner diameter, and to a process for operating the apparatus.

A bonded joint for use in bonding composite materials is provided and includes a composite rib having electrically conductive properties and a composite structure having electrically conductive properties. An electrically conductive preform is provided that facilitates a bond between the composite rib and the composite structure. A mesh composition that bonds the composite rib to the preform and that bonds the preform to the composite structure is provided and is electrically conductive to conduct current between the composite rib and the composite structure.

A joining structure includes a first member, a second member of a material different from that of the first member, and a separation mechanism provided between the first member and the second member and that separates the first member and the second member from each other, wherein a resin is filled into the space between the edge of at least one member among the first member and the second member, and the other member.

A device for sealing sample tubes comprises a tool assembly configured to interface with a rack (10) holding a plurality of sample storage tubes (20), the tool assembly holding a plurality of punches (322) and a die plate (324) including a plurality of cutting holes, with each of the plurality of cutting holes accepting one of the plurality of punches (322). The tool assembly receives a foil sheet (131) between the punches (322) and the die plate (324). The device includes an actuator enabling linear movement of the tool assembly. Linear movement of the tool assembly towards the rack (10) engages the die plate (324) against the rack (10) and punches the punches (322) through the cutting holes of the die plate (324) to punch a plurality of sealing sections from the foil sheet (131) and to press and seal each of the sealing sections against a top end of each of the plurality of sample storage tubes (20) in the rack (10).

A method of manufacturing the synthetic resin welded body includes the steps of: preparing an oil passage forming member including a welding portion having a top portion serving as a welding face; preparing a baffle plate having a welded face; disposing the oil passage forming member and the baffle plate so that the welding face comes in contact with the welded face; and radiating laser light to the welding portion to weld the welding face and the welded face. A recess is formed in the baffle plate so that a groove portion is formed along an outer peripheral face of the welding portion when the oil passage forming member and the baffle plate are disposed so that the welding face comes in contact with the welded face.

Provided is packaging machine with a sealing station that includes a mold with an upper tool and a lower tool facing each other and suitable for cooperating with one another in an operative position of the mold, between which there is delimited an inner area. The lower tool includes a cavity that is configured to receive a tray. A gas injection opening is located adjacent to a first side of the cavity and communicated with the inner area. The upper tool includes a sealing tool and an actuator device facing an actuation region of the lower tool defined between the first side of the cavity and a contact location of the upper and lower tools, and being closer to the lower tool than the sealing tool.

Two workpieces 30, 40 are joined by means of ultrasound. First, a workpiece 30 with at least one energy direction sensor 31 and a second workpiece 40 are provided. The workpieces are brought into contact with each other in such a way that the energy direction sensor 31 comes into contact with a first surface 41 of the second workpiece 40. Ultrasonic vibrations are then introduced into one of the workpieces 40 via a working surface 11 of a sonotrode 10. A sonotrode 10 is used, which has a contour with contact lines 12 on the working surface 11. The sonotrode 10 is positioned with respect to the first workpiece 30 in such a way that the contact lines 12 run transversely to the energy direction generator 31.
