A flow cell and a method for connecting components of a microfluidic flow cell, in particular for integrating component parts into a carrier structure of the flow cell, in which a gap is formed between the components to be connected. The gap is filled with a solvent. The material of at least one component bordering the gap dissolves in the solvent and the material completely fills the width of the gap and partially fills the height thereof after evaporation of the solvent.

A lamination system includes a film supply, a non-woven material supply, and a laminator. The laminator causes a film from the film supply to be laminated to a sheet from the non-woven material supply to establish a laminated sheet.

The present invention provides a connecting piece implanting device and a connecting piece implanting method. The connecting piece implanting device includes a base, a feeding unit, a pressing unit, a sliding platform and a fixed pressing block. The sliding platform is arranged on the base, and the fixed pressing block is arranged above the sliding platform. The pushing device has the following beneficial effects: firstly, the push plate is divided into two parts for clamping the connecting piece most importantly, so as to completely eliminate rollover, upwarp and other malposition problems of the connecting piece, secondly, the push plate can be freely changed according to the thickness of the connecting piece, thus the application range is wider, and thirdly, a convex plate and a concave plate are arranged to effectively prevent empty pressing and wrong pressing.

A multipurpose spatula which has a separable pressing member on the outer surface of a body thereof. The pressing member is rotatable as required to allow a side surface thereof to be located on the end of one side pressing piece. This minimizes the occurrence of scratches on sheets attached to advertising signs and tables, etc. and also promotes user conveniences.

A film pasting tool is used to paste one surface of a film on a member-to-be-pasted at a predetermined position. The tool comprises a flexible tabular body, a first adhesive part, a front surface thereof being adhesive, provided on one surface of the body, and a second adhesive part, a front surface thereof being adhesive, provided on a part of a region other than a region where the first adhesive part is provided out of one surface of the body. An other surface of the film is pastable on the front surface of the second adhesive part, and when the other surface of the film is pasted on the front surface of the second adhesive part, the front surface of the first adhesive part is exposed in such a manner that the front surface of the first adhesive part is pastable on the member-to-be-pasted.

Methods for reworking structures and reworked cellular core panels, reworked structures comprising the reworked cellular core panels, and guides and cutting apparatuses for reworking cellular acoustic panels and reworking cellular non-acoustic panels are disclosed.

The present invention relates to a method for welding a 3D bellows. The method includes: repeatedly laminating a unit cell material, a second adhesion-preventing film, a different unit cell material, and a first adhesion-preventing film; forming ventilation holes on the unit cell materials by pressing a hole-processing cutter on which a hole-circumference welding heater is installed onto the laminated unit cell materials and the first adhesion-preventing films, and then heating the circumference of the ventilation holes; finishing two sides of the unit cells by positioning, on two outermost surfaces of the laminated unit cell materials, a first finishing unit cell material and a second finishing unit cell material provided with an air injection port; and cutting the first finishing unit cell material, the unit cell materials, and the second finishing unit cell material and heating the periphery of the cut area by pressing a contour-processing cutter.

A method for inserting an insert into a hole in a composite material made from a plurality of carbon fiber layers suspended in a resin material includes lowering a temperature of the insert to a reduced temperature at which a coefficient of thermal expansion of a material of the insert causes the insert to contract to a first perimeter, inserting the insert at the reduced temperature into the hole, and permitting the temperature of the insert to increase from the reduced temperature to an operational temperature. At the operational temperature, the insert expands to a second perimeter so that the insert is retained within the composite material due to an interference between the insert and the composite material. The interference transfers a structural load from the insert to the composite material and results in damage to the composite material if the insert is dislodged at the operational temperature.

The invention relates to a device for a vacuum cleaner filter bag comprising a holding device with a passage opening and a closure device for closing the passage opening of the holding device, wherein the closure device comprises a closure flap and an elastic element made of a cross-linked silicone elastomer, and the elastic element is pretensioned in a state in which the closure flap closes the passage opening of the holding device.
