A biodegradable container including a unitary polymeric body element having a top portion and a cylindrical body portion. The top portion has a cylindrical neck wherein the cylindrical neck defines an inner surface and an outer surface. The container further includes a polymeric bottom element welded to the cylindrical body portion of the unitary polymeric body element. A polymeric cap defines an internal rim configured to be received by the inner surface of the cylindrical neck. The polymeric cap includes an external cover having an interior surface which may be tapered so that the outer surface of the cylindrical neck and the interior surface of the external cover form an inner seal. The interior surface of the external cover may also form an outer seal with the outer surface of the cylindrical neck when the polymeric cap is in a closed position.

The present disclosure relates to a battery module that includes a housing having a first protruding shelf along a first perimeter of the housing, a second protruding shelf along a second perimeter of the housing, where the first and second protruding shelves each include an absorptive material configured to absorb a first laser emission. The battery module also includes an electronics compartment cover configured to be coupled to the housing via a first laser weld, and a cell receptacle region cover configured to be coupled to the housing via a second laser weld. The electronics compartment cover has a first transparent material configured to transmit the first laser emission toward the first protruding shelf and the cell receptacle region cover has a second transparent material configured to transmit the first laser emission or a second laser emission toward the second protruding shelf.

Methods for joining a first blade component and a second blade component of a rotor blade together includes printing and depositing, via a computer numeric control (CNC) device, at least one three-dimensional (3-D) grid structure at a first joint area of the rotor blade. The first joint area contains the first blade component interfacing with the second blade component. The method also includes providing an adhesive at the first joint area to at least partially fill the grid structure. Further, the method includes securing the first blade component and the second blade component together at the first joint area via the adhesive.

The invention is about an ultrasonic welding-based microfluidic device. It is mainly made of a first element and a second element welded one to the other via at least one structure (10, 10). The structure (10, 10) comprises an elongated welded portion for said welding, a welding channel (12, 12) extending between the first and second elements and along one side of the welded portion, and a draining channel (13) communicating with the welding channel (12, 12) and the microfluidic path (20, 20) of the device. The invention is further about a method of manufacturing such a device.

The present disclosure relates to a battery module that includes a housing having a first absorptive material configured to absorb a laser emission, a cover having a second absorptive material configured to absorb the laser emission, and a collar configured coupled to the housing and coupled to the cover via a laser weld. The collar includes a transparent material configured to transmit the laser emission through the collar and toward the housing or the cover.

A method of fastening a second object to a first object includes: providing the first object with an attachment surface; providing the second object; placing the second object relative to the first object, with a resin composition in between the attachment surface and the second object, wherein the resin composition has a resin having a first viscosity and being in a flowable state; pressing the first and second objects against each other and causing mechanical vibration to act on at least one of the objects until the resin composition experiences a vibration induced activation, which includes at least one of reduction of the viscosity of the resin compared to the first viscosity and activation of particles dispersed in the resin. The pressing and mechanical vibration are continued or repeated until the resin has at least partially cross-linked and the viscosity of the resin is increased compared to the first viscosity.

A housing includes a first surrounding wall connected around a base wall. The first surrounding wall has a first joint portion opposite to the base wall, a first outer surface and a first inner surface. The first outer and inner surfaces extend from the first joint portion toward the base wall. The first joint portion is stepped and has a first projecting portion adjoining the first outer surface, and a first shoulder portion indented from the first projecting portion and proximal to the first inner surface. The first shoulder portion has a plurality of parallel spaced-apart ribs protruding therefrom in a same direction as the first projecting portion. Each of the ribs has a tip that does not extend beyond a top end of the first projecting portion.

The first electrode section (7a) and the second electrode section (7b) are formed such that the outer portion connected to the upper portion of the heating section (6) is thinner than the inner portion connected to the lower portion of the heating section (6). The heating section (6) and the first electrode section (7a) are interconnected by an R-shaped first connecting portion (21). The inner circumferential sloping surface of the heating section (6) and the second electrode section (7b) are interconnected by an R-shaped second connecting portion (22). The first and second connecting portions (21)(22) are formed such that R becomes larger from the upper end to the lower end, where the upper portion is thin and the lower portion is thick. The thickness of an intermediate portion (6b) is smaller than the thicknesses of the first and second connecting portions (21)(22).

A method of assembling a fan wheel includes forming a first wheel portion including a first plurality of impeller blades and a first connector, forming a second wheel portion including a second plurality of impeller blades and a second connector, affixing an end of each of the first plurality of impeller blades to a first surface of a support ring such that the first connector is affixed to the second connector, and affixing an end of each of the second plurality of impeller blades to a second surface of a support ring.
