An integrated testing device and fluid module are disclosed, as well as a method of manufacture. Fluid module contains a reservoir containing a test fluid, and a control vessel. The reservoir discharges test fluid into the control vessel, which discharges the test fluid in a controlled way to a test component.

A housing, in particular a battery housing, includes a wall, wherein the wall is formed, at least is some areas, from a multi-layered material. The wall encompasses an arrangement area which is formed by bending the material.

Disclosed herein is an apparatus for folding a side extending outward from a cup part in a battery case of a pouch-type secondary battery. The apparatus can include a body having a plate shape, adjacent to the side, and disposed to be elongated in a longitudinal direction of the secondary battery, wherein the body includes, a heating part disposed at one side thereof to heat an inner portion disposed at a relatively inner side of the side, and a pressing part disposed at the other side thereof to press an outer portion disposed at a relatively outer side of the side. When the heating part heats the inner portion, the body rotates to allow the pressing part to press the outer portion.

The present invention relates to a pouch-shaped secondary battery sealing apparatus and a pouch-shaped secondary battery manufacturing method capable of radiating an infrared laser to a sealed portion in an overlapping state, whereby it is possible to increase sealing force, to prevent occurrence of wrinkles, and to reduce sealing time when forming a sealed portion of a pouch-shaped secondary battery case.

The present invention relates to a pouch-shaped battery case sealing apparatus capable of adjusting a direction in which an upper sealing block configured to press a laminate sheet applies pressure to the laminate sheet during a process of applying heat and pressure to an outer periphery of a battery case made of the laminate sheet to seal the outer periphery of the battery case when a pouch-shaped battery is manufactured and a pouch-shaped secondary battery sealing method using the same.

A device internally insulating a welded pipeline joint between pipes having an internal protective coating, in a first variant, includes a power actuator having a cylindrical elastic working member for radial expansion when excess pressure occurs inside its cavity. A cylindrical casing of elastic anti-adhesive material arranged coaxially on the member exterior can have channels for exhausting air and supplying a compound. In a second variant, the device sleevelessly insulates an annular space. A casing made of an anti-adhesive material is centrally reinforced by an elastic cord. Using a cylindrical elastic anti-adhesive casing coaxially arranged on the exterior of a power actuator elastic working member forms an annular space in the weld zone either using a protective sleeve, or by a reinforced casing portion. A vacuum in the space is filled by a compound. The elastic anti-adhesive material allows easy removal of the casing from the hardened compound surface.

The invention relates to an assembly for adhesively connecting substantially congruent gluing surfaces of a first and second joining partner over their full surface, comprising: the first joining partner (1); the second joining partner (2); an adhesive layer (3) of a polar, flowable adhesive applied to the gluing surface (1a) of the first joining partner (1); means (8) for holding the second joining partner (2) above the adhesive layer (1a) of the first joining partner (1), such that the gluing surface (2a) of the second joining partner (2) faces the adhesive layer (3) on the first joining partner (1) and is disposed so as to be spaced therefrom across an air gap (5), and the spacing defined by the air gap (5) between the first joining partner (1) and the second joining partner (2) is dimensioned in such a way that a capillary volume is formed; means (7) for generating an electric field (10) in order to cause, by means of electric influence, a local charge displacement (11) on and/or in the second joining partner (1), and the charge displacement (11) is suitable for attracting the polar adhesive in such a way that it wets the gluing surface (2a) of the second joining partner (2) first in the area of the local charge displacement (11), wherein the means for generating the electric field comprise an electrode (7), which is disposed on the side of the second joining partner (2) facing away from the gluing surface (2a) and is electrically insulated from said partner (2).

The present invention relates to a pouch-shaped battery sealing apparatus including a stopper capable of adjusting a thickness after sealing in a process of sealing the outer edge of a battery case made of a laminate sheet by applying heat and pressure thereto when a pouch-shaped battery is manufactured and a pouch-shaped battery sealing method using the same.

The present invention relates to a pouch-shaped battery sealing apparatus including a position adjustment unit capable of adjusting relative positions of an electrode lead and an insulative film before sealing during a process of applying heat and pressure to an outer periphery of a battery case made of a laminate sheet to seal the outer periphery of the battery case when a pouch-shaped battery is manufactured and a pouch-shaped battery sealing method using the same.

A method for welding at least two parts including a thermoplastic material and having respective surfaces to be welded, including: inserting an insert between the surfaces to be welded of the two parts; generating heat via the insert; wherein the insert moves in relation to the parts to be welded in a welding direction. Also, an installation adapted for implementation of this method.
