A packaging device includes a first sealing device which performs a first sealing process based on an impulse seal method on a bag in a chamber being in a vacuum state. A second sealing device performs a second sealing process based on a heat plate sealing method on a planned seal portion of the bag. A cooling device cools the bag. A discharge unit receives, in the release position, the bag released from the transfer mechanism after the cooling process. The transfer mechanism linearly transfers the bag in a direction along a surface of the bag from the delivery position to the release position.

Overmolded inserts and methods for forming the same The present disclosure is directed to overmolded inserts (100) with reduced internal residual stress and corresponding methods for forming the overmolded inserts. The overmolded inserts have a polymer housing; metal or metal allow tapered insert (104, 302) and a compression element (106, 304) disposed between the housing and the distal end of the tapered insert. During formation, the tapered insert and compression element are placed within a mold. The polymer housing material is heated and filled into the mold. As the polymer housing cools, the compression element is compressed between the polymer housing and the tapered insert. The overmolded inserts formed have reduced internal residual stress relative to a corresponding insert formed from non-tapered insert.

One aspect is a manufacturing method including providing at least a first electrically conductive wire with an electrical insulation and a second electrically conductive wire with an electrical insulation, providing a first and a second ring electrode surrounding the wires, electrically connecting the first ring electrode with the first wire and the second ring electrode with the second wire, bundling the ring electrodes and the wires by means of a first sheath surrounding the ring electrodes and the wires to obtain a first ring electrode component, providing a second ring electrode component, bundling the ring electrode components by means of a second sheath surrounding the ring electrode components, and partially removing the first and the second sheaths from the ring electrodes to expose ring electrode portions.

A pipe joining system and pipe joint are shown m which two sections of molecularly oriented pipe are joined using heat shrinking techniques. A first section of pipe is provided having a straight, pre-formed socket with an internal diameter and with an end opening having enough clearance to allow a mating spigot section having a given external diameter to be inserted into the socket end opening. After the spigot end is inserted to a given depth, the socket is heated sufficiently so that the internal diameter of the socket end comes into contact with the external diameter of the spigot end, the molecularly oriented pipe being in a rubbery state and exhibiting a low elastic modulus which allows the socket end to conform tightly to the spigot end external diameter without deforming the spigot end.

A method and apparatus for assembling a high purity liquid distribution system is described. A distal end portion of the tube is heated then pushed over a sleeve so that the distal end portion can have a shrink seal fit over the sleeve to mitigate accidental or inadvertent pull out of the tube from a fitting. Other benefits are also achieved such as minimal flow restriction of the liquid flowing through the joint and the tube.

Systems, apparatuses, and methods of protecting the outer surface of a cylinder for containing fluid. The cylinder includes a heat shrinkable polymer sleeve configured to shrink onto the cylinder with the application of heat. The apparatuses include and a ventilated enclosure having a heating assembly configured to distribute heat gradually or in increments to the shrinkable polymer sleeve.

A portable drug testing device for handheldly collecting a sample from exhaled breath of a subject for further sensor based analysis. The portable drug testing device comprising a housing comprising at least one inlet and at least one outlet for the exhaled breath to exit through, and a sampling membrane arranged in the housing. a tubular element having a mouthpiece section for the subject to exhale into, and a selective trap section in fluid communication with the mouthpiece and the inlet of the housing having a non-straight gas flow path for letting aerosols pass through the tubular element. The sampling membrane is arranged to collect the aerosols from the exhaled breath. The portable drug testing device further comprises a volume measure unit for determining that a pre-defined volume of the exhaled breath has passed through the sampling membrane.

A workpiece unit containing a workpiece body is provided. A method for producing the workpiece unit is also provided. The workpiece body contains a plurality of sections. The sections divide the processing surface of the workpiece body. The size of each section of the workpiece body can be adjusted or selected according to the demand so that it is possible to increase utilization efficiency of the workpiece body.
