Implementations described herein include a system for guiding medical waste fluid into a medical waste collection canister. The system includes a manifold and a filter. The manifold includes a top surface and a sidewall extending from the top surface in a first direction. The top surface and the sidewall define an interior chamber of the manifold. The top surface includes an inlet port and a vacuum port disposed therein. The inlet port connects to a source of medical waste fluid and the vacuum port connects to a vacuum source. The manifold can be formed from a first polymer. A filter is positioned within the interior chamber of the manifold and immediately upstream of the vacuum port so as to filter air flowing into the vacuum port. The filter extends away from the top surface of the manifold in the first direction and the filter is formed from a second polymer. The filter is fused to a surface of the interior chamber of the manifold or to a peripheral surface of the vacuum port so as to form a fused interface, and not merely a press fit connection.

Method of making a shaped article (5) comprising at least two parts (10, 15) wherein the first part comprises at least one projection (20) and the second part comprises at least one recess (22) by preparing said first part and said second part in a moulding process and joining the prepared first and second part together by engaging the at least one projection with the at least one recess to form said shaped article.

A fuselage structure of an aircraft includes a fuselage skin, and a plurality of frame elements spaced apart from one another in a direction parallel to the aircraft longitudinal axis for supporting the fuselage skin. The fuselage skin includes a plurality of interconnected fiber-reinforced composite skin panels that extend between each pair of frame elements and are connected thereto. The composite skin panels further comprise a stiffener integrally formed in each composite skin panel. A method for manufacturing the fuselage skin. The composite skin panels may be interconnected and/or connected to a frame element through an induction welded connection.

A method for manufacturing a turbo fan unit includes a step for preparing multiple fan blades and an other-side side plate, and a step for connecting each of the multiple fan blades to the other-side side plate by a welding process. In the preparing step, one of the fan blade and the side plate is prepared, in which a connecting-surface forming portion having a connecting surface and a welding projection protruded from the connecting surface is formed. The connecting surface connects one of the fan blade and the side plate to the other one of the fan blade and the side plate. In the connecting step, the welding projection is melted down and the connecting surface is connected to an opposing surface, which is the surface of one of the fan blade and the side plate and which is opposing to the connecting surface.

The present disclosure can provide for an ultrasonic welding method for a pair of workpieces. The method can include first pressing an ultrasonic welding stack against a first workpiece in the pair so that the first workpiece comes into contact with a second workpiece in the pair. The method can then provide for initiating a weld phase by outputting energy from the ultrasonic welding stack to the first workpiece. The method can provide for monitoring, with at least one sensor, a sensed parameter. The sensed parameter can be, for example, weld force and/or weld force rate of change. The method can provide for determining whether the sensed parameter has reached a predetermined level. Based on determining that the sensed parameter has reached the predetermined level, the method can provide for ending the weld phase.

A method of mechanically securing a first object including a thermoplastic material in a solid state to a second object with a generally flat sheet portion, with a perforation of the sheet portion, and with the sheet portion having an edge along the perforation is provided, wherein the first object is positioned relative to the second object so that the edge is in contact with the thermoplastic material and wherein mechanical vibration energy is coupled into the assembly including the first and second objects until a flow portion of the thermoplastic material due to friction heat generated between the edge and the thermoplastic material becomes flowable and flows around the edge to at least partially embed the edge in the thermoplastic material. After the mechanical vibration stops, the thermoplastic material is caused to re-solidify, whereby the re-solidified thermoplastic material at least partially embedding the edge anchors the first object in the second object.

A method of making an aircraft blade is provided. The method comprises the steps of: assembling two or more fibre-reinforced thermoplastic composite parts into a blade assembly; and welding the fibre-reinforced thermoplastic composite parts together utilising an additional thermoplastic located at least at locations where the parts will abut when assembled. The additional thermoplastic has a melting or softening temperature lower than a melting temperature of each of the fibre-reinforced thermoplastic composite parts being assembled. The step of welding comprises heating the blade assembly to a temperature above the melting/softening temperature of the additional thermoplastic and below the melting temperature of each of the fibre-reinforced thermoplastic composite parts so as to melt/soften the additional thermoplastic and thereby weld the fibre-reinforced thermoplastic composite parts together to form the aircraft blade.

A method for joining a lens to a housing of a lighting device of a motor vehicle, in which the housing is accommodated and secured in a receptacle device. The method includes accommodating the lens in a pre-centering device, aligning the lens towards the housing during an alignment procedure and accommodating the lens by a holding device after the alignment procedure. The method further includes holding the lens by the holding device during a subsequent joining process, releasably attaching the holding device to the pre-centering device, aligning, via fastening elements, during the alignment procedure and moving the accommodated lens and the holding device attached to the pre-centering device relative to the receptacle device such that the lens and the holding device are aligned on the housing accommodated in the receptacle device.
