Abstract: A telescopic seating system with aisle rails in the form of discrete and lightweight uprights. A telescopic seating system, such as a bleacher system or a platform seating system, is equipped with a series of uprights, which are easily movable to positions whereby the seating system can be retracted. The railing system includes discrete lightweight and movable uprights, each having a single closed-loop upper section. The noses of the decks upon which rows of seating are mounted have sockets which receive the lower end of each upright and support the uprights in the aisles of the seating system. Because the uprights are lightweight, discrete and easily moveable, the tendency to use the seating system without installing the handrails is reduced or eliminated.

Abstract: To improve sound damping in prefabricated building elements having two parallel welded wire mesh mats 1, 2, interconnected by web wires 7, 7′ enclose, therebetween, an insulating body (8) for example of foam plastic. Concrete is then sprayed on both sides over the mesh wires to form inner and outer shells. These concrete shells are interconnected by forming the insulating body with through-holes, which, upon concrete spraying, will form concrete webs or plugs (14, 14′) interconnecting the two shells, thus preventing resonant sound vibrations of the concrete shells. The through-holes (10, 11, 11′) can be molded during manufacture of the insulating body (8) or drilled or stamped therethrough, and may extend at right angles through the major extent of the foam body or obliquely, preferably downwardly and distributed randomly.

Abstract: Banknotes emerging from a currency processing machine with a plurality of formation channels advance in succession along respective ducts of which the runouts are equipped with respective rollers positioned to pick up the notes, transfer them to each channel and stack them on a first shelf. An occluding mechanism operating at the inlet of each channel causes groups of the notes to accumulate on the corresponding first shelf, each of which is picked up by a first gripper and transported toward a first strapping/banding station where a gripping mechanism takes up a continuous strip of banding material by the leading end and passes it around each successive group; the strip is cut into discrete lengths by a tool designed also to seal the leading end to the trailing end of the cut length, banding the group to fashion a bundle which is then transferred to a second shelf and carried by this same shelf toward the outlet of the channel.

Abstract: Filler strips made of a solid layer of thermal sealable material, such as separate strips of polyethylene film or other suitable thermal sealable films, are sequentially spaced on one side of a thermal sealable plastic mesh web at equal distance from one another. The pre-prepared web is used on a conventional form, fill and seal machine to form mesh bags having top and bottom fin seals with enhanced strength. The bag is primarily mesh so the product within the bag breathes easily. A thermal sealable print band may be located on the second side of the mesh. Different types of bags can be formed on different types of automatic form, fill and seal machines by modifying the specific configuration of the pre-prepared mesh web for the particular automatic form, fill and seal machine design.

Abstract: This Power air blower fan head mobilizer of matted vegetation solves the problem of blowing leaves and other debris matted together by wind or rain. A flexible serrated mobilizer probe (composed of metal, plastic, or composite) is inserted into the terminal fan head air nozzle of an air or leaf blower in such a way that a mass of often wet debris is stirred, tossed, moved, and cut. Thus, the invention opens pathways into the matted mass so that airflow is effective. The device includes a curved sharp terminus, which acts as a vegetation cutter on both flat and irregular surfaces. Large stemmed vegetation and small limbs can also be sawed in two because the probe has coarse and fine serrations on its respective lateral sides. In addition, the 5 inch projecting curved probe terminus provides a spring skid to reduce weight of the power air blower, thus saving energy of the operator.
