An encapsulation system for use in securing a rock bolt in a bore hole drilled into a rock face to be stabilised, the encapsulation system comprising at least two separate encapsulation mediums and one or more elongate cartridges containing the encapsulation mediums, each the cartridge having a frangible casing, the encapsulation mediums including: a first encapsulation medium comprising a curable first resin formulation; and a second encapsulation medium; wherein, following use in securing a rock bolt, the second encapsulation medium has a lower bond strength and/or a lower compressive strength than the first resin formulation.

[PROBLEM TO BE SOLVED]

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.

[SOLUTION]

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.

A fastener-receiving insert system includes a fastener-receiving insert having a proximal end and a distal end and at least one adhesive-dispensing chamber adjacent to the distal end of the insert, containing at least one part of an adhesive material within a chamber wall. The fastener-receiving insert system further includes a puncturing device operably engaged with and configured to puncture the chamber wall to release the at least one part of the adhesive material around the fastener-receiving insert.

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.

The invention is an expanding, anchoring screw, made of expandable polymer material. The screw shaft is hollow. After inserting screw in a material, by allowing two reagents to mix in the hollow shaft, and a polymerization chemical reaction to occur, the reagents increase in volume exerting pressure against the inner surface of the hollow shaft, expanding the shaft, and applying greater anchoring force against material in which the screw is inserted.

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.

An encapsulation system (100) for use in securing a rock bolt in a bore hole drilled into a rock face to be stabilised, said encapsulation system comprising at least two separate encapsulation mediums (112,122) and one or more elongate cartridges (110,120) containing said encapsulation mediums (112,122), each said cartridge having a frangible casing (111,121), said encapsulation mediums including: a first encapsulation medium (112) comprising a curable first resin formulation; and a second encapsulation medium (122); wherein, following use in securing a rock bolt, said second encapsulation medium has a lower bond strength and/or a lower compressive strength than said first resin formulation.
