A game apparatus consisting of a housing with a game playing surface. A ball is rolled on the playing surface by a conventional shooting device. The playing surface has openings and the ball, propelled from the front towards the rear end, falls into one of the openings, enters into the interior of the housing and rolls back towards the front end. One opening towards the rear end is designated as a "functional" opening and the interior of the housing has electrical wiring and a switching device for starting and stopping a motor which rotates a multi-disc assembly whenever the ball falls into the "functional" opening.
This application is a continuation-in-part of my co-pending application Ser. No. 222,667 filed on Jan. 2, 1981 now U.S. Pat. No. 4,477,078 which, in turn, is a continuation of Ser. No. 023,730, filed Mar. 26, 1979, now U.S. Pat. No. 4,264,073 granted Apr. 18, 1981.
The apparatus is provided to make a melt blown fibrous medium and includes first and second melt blowing dies for respectively issuing first and second streams of melt blown fibers along first and second melt blown paths. The first and second streams are issued on a forming surface where the streams are collected to form a melt blown fibrous medium. A movable transfer surface is interposed between the first die and the forming surface in the first path so that the first stream of melt blown fibers impinges on the transfer surface in advance of the forming surface such that the first stream is transferred to and brought into contact with the second stream of melt blown fibers on the forming surface.
Filtration medium is formed of a mass of nonwoven melt blown support and filtration fibers which are integrally co-located with one another. The support fibers have, on average, relatively larger diameters as compared to the filtration fibers which are integrally co-located therewith. Preferably, the filtration medium is disposed within at least one annular zone of a filtration element, for example, a disposable cylindrical filter cartridge having an axially elongate central hollow passageway which is surrounded by the filtration media. A depth filter cartridge in accordance with the present invention may thus be formed having one or more additional filtration zones (which additional filtration zones may or may not respectively be provided with integrally co-located support fibers) in annular relationship to one another. As a result of the melt blown, nonwoven fiber structure in accordance with the present invention whereby at least one filtration zone is comprised of relatively larger diameter support fibers integrally co-located with relatively smaller diameter filtration fibers, a filter cartridge having a wide range of "engineered" physical properties (e.g., in terms of filtration, pressure drop tolerance and the like) can be provided.
