To provide a method for readily forming an easily separable portion having an adhesive strength that is required as a package bag on packaging film, a package bag having an easily separable portion formed by this method, and a filling-packing machine utilizing this method. A method forming an easily separable portion in packaging film by interposing at least two packaging films between a horn emitting ultrasonic waves and an anvil oppositely disposed to the horn, and vibrating the packaging films by the ultrasonic waves, in which a vibratable layer is provided on the packaging film in at least one of the horn side and the anvil side.

In an embodiment, an expansion component (e.g., expanding foam element, inflatable pad, a pneumatic or hydraulic mechanism, etc.) is arranged inside of a battery module compartment (e.g., on a bottom interior surface of the battery module compartment). A battery module is inserted into the battery module component and is fixated, or secured, within the battery module compartment at least in part based upon the expanding component which starts to expand or continues to expand after the insertion. In a further embodiment, the battery module may be removed from the battery module compartment after a contraction function (e.g., collapse of the foam element, deflation of the inflatable pad, etc.) of the expansion component is initiated.

A ready to use composite anchor plug kit, pre-assembled with adhesive/s or compounds (20, 21) and spill catchment film (11), which does not need separate adhesive/s or compounds to be inserted, injected or applied in or on the body of the anchor plug for the purposes of increasing the resultant anchoring strength. The anchor plug has a detachable, adhesive backed, spill containment and collection film (11) designed to protect the immediate surrounding surface work area from the extra adhesive (20, 21) seeping out. The adhesive (20, 21) overspill is collected on the film surface, which can be detached & discarded, thereby ensuring a neat & clean uncontaminated area around the anchored borehole.

The body of the anchor plug (16) is sealed with a pressure retaining diaphragm seal plug (15) with self-sealing, leak-proof properties, designed to retain the generated pressure within the cavity of the anchor plug (16), after it is pierced and threaded through with an anchor.

A panel fastener and panel fastening system are provided. The panel fastener includes a body having a collar and an elongated shank extending from the collar. The elongated shank defines an interior space and having a penetrating tip disposed at an end opposite of the collar. The panel fastener also includes a substrate fastening portion configured to be driven into a substrate and a holding mechanism connected to the substrate fastening portion and configured to engage the substrate.

Friction stabilizer pull tester apparatus and method for testing friction stabilizer type rock bolts including a pull tester toolhead comprising a tension rod with a radially expanding collet device inserted and expanded in a friction stabilizer steel tube. A confining collar on the tension rod for restricting longitudinal movement of the expanding device and outward deformation of the friction stabilizer tube at a friction stabilizer ring flange. A pre-tensioning device applies an initial force to seat apparatus and a pulling apparatus applies a greater load force to the tension rod to determine load capacity of the friction stabilizer.

A metal collar attached in a through-hole of FRP member includes first and second collar members. The first collar member includes outer and inner circumferential surfaces. The outer circumferential surface is in contact with a hole inner circumferential surface of the through-hole. A slit is formed in a part in a circumferential direction of the first collar member. The second collar member applies a pressing force radially outward to at least a part of the inner circumferential surface of the first collar member or a pressing force to inner surfaces of the slit in a direction in which the inner surfaces separate from each other in the circumferential direction. The second collar member is held in the first collar member by reaction of the pressing force, deforms the first collar member for diameter expansion with the pressing force, and presses the outer circumferential surface against the hole inner circumferential surface.

In an embodiment, a battery module fixation arrangement includes gaps arranged between fixation recesses and fixation pins. Upon insertion of a battery module into a battery module compartment, each gap is at least partially filled with a curing material that cures after the insertion. In a further embodiment, the fixation recesses may include cartridges that comprise a foam material along with multiple components that mix to form the curing material after the insertion.
