Abstract: The present invention is to provide a package bag having a metal layer, wherein the metal layer is formed with a first groove and a second groove, and the second groove has a first side extending to one edge of the metal layer and a second side away from said edge and communicating vertically with a central section of a first side of the first groove. The second side of the second groove is shorter than the first side of the first groove, such that the portions of the metal layer adjacent to the first side of the first groove form two first impedance-matching portions respectively, and the two corresponding portions of the metal layer adjacent to the first groove form two second impedance-matching portions respectively. Thus, due to the impedance-matching portions, a slot antenna can be formed on the metal layer for coupling with a communication device attached thereto.

Abstract: The illustrative embodiments described herein are directed to apparatuses, systems, and methods for managing liquid flow associated with a tissue site that involves using reduced pressure to control fluid flow. In one instance, an apparatus includes a first valve and a second valve in fluid communication with a reduced-pressure source. The valves are movable between an open position and a closed position and are operable to change flow status (open to closed or vice versa) based on a presence of reduced pressure. At least one of the first valve or the second valve is in the closed position to obstruct a flow of a liquid while the other is in the open position. The apparatus also includes a reservoir fluidly coupled to the first valve and the second valve. Other systems, methods, and apparatuses are presented.

Abstract: A book of matches includes a plurality of matches each of the matches having a match base that includes a flammable match tip at a first end and a remaining end that is disposed opposite to the first end. Each match base at the remaining end is attached to a central strip. An improvement is made to each match base near the remaining end to facilitate removal of the match from the central strip. The improvement consists either of at least one perforation passing through the match base, at least one score line that is cut or impressed into the match base, or a combination of at least one score line and at least one perforation.

Abstract: The mixing bucket and integral mold (10) has frustoconical walls (12), a bottom wall (14), a bottom rim (32) and top rim (24). A lid (16) closes and seals the bucket. A bail (28) is provided for lifting and carrying the bucket. A flange (38) that is integral with the bottom wall (14) and inside the bottom rim (32) reinforces and supports the bottom wall and forms a mold cavity (36). Agitators (60) each of which has a base, an integral post (68) and agitation surfaces (72) are attached to the inside surface of the frustoconical walls (12) along two helixes (62,64). The agitation surfaces are shaped and oriented to agitate and mix material when the bucket is rolled on its side walls (12). The agitation surfaces can be shaped and oriented to merely divide the material being mixed, to move material toward the lid (16), to move material toward the bottom wall (14), to move material radially inward toward the central axis (18) or to move material radially outward toward the side walls (12).

Abstract: A hydration-expansive crushing cartridge which is prepared by filling a hydration-expansive crushing agent into a container made of a material which allows the permeation or penetration of water and which can be broken by an external force. The cartridge can be charged into holes bored in a concrete structure, a rock bed or the like to crack it regardless of the positioning or the direction of the bored holes and which has a homogeneous crushing capability.

Abstract: A capsule for use in anchoring contains as dry ingredients a so-called high alumina cement, a set retarding agent and at least one water-soluble lithium salt. The capsule has a perforated wall and in use is wetted in water to form a self-setting anchoring composition which has a controlled initial setting time followed by an acceptable final setting time after a short interval.
