Abstract: An assembly of hollow frustum-shaped bodies arranged and supported on a horizontal support structure is used to form a core structure for water retention cells. The assemblies are arranged in alternately inverted layers with the ends of the frustum-shaped bodies interconnected to form vertical support columns which are horizontally stabilized by horizontal support structure.

Abstract: The filling noise generated inside a pressurized container when liquid is injected into the container is detected at the outer end of a vent tube which extends into the container. When the level of liquid in the container reaches the lower end of the vent tube, the filling noise detected at the outer end is abruptly diminished. This abrupt change is detected and used to automatically terminate filling of the tank.

Abstract: Tray units adapted to be mounted on and extend from the front edges of conventional display shelves for supporting and displaying merchandise are provided with mounting support means which attach the tray to the display shelf. The support means includes a first member which extends horizontally from the back side of the tray and a plurality of posts which depend from the first member and extend parallel therewith and rearwardly therefrom. The tray may be simply attached to and supported from the front edge of the shelf by inserting the posts into holes in the shelf so that the first member rests on the top surface of the shelf and the posts rest on the bottom surface of the shelf.

Abstract: A simulated gun launches a retrievable projectile in the form of a cylinder containing a compressible spring. The spring is compressed by inserting the barrel of the gun into the bore of the cylinder. A tab on the end of the cylinder rides in a helical groove on the surface of the barrel to cause the projectile to rotate about the axis of the barrel as the projectile is launched.

Abstract: A passive venting device for venting enclosures comprising a base member, an intermediate splash member including a diverter, and a top, dome-shaped member. In a preferred embodiment, the diverter may be molded as a single unit of manufacture with the base member. The venting device allows air and other gases to escape from within an enclosure to be vented while preventing the intrusion of moisture, such as rain or snow, into the enclosure.

Abstract: A composite membrane comprising a layer of rubberized asphalt having a heavy duty plastic film layer continuously bonded to one side and, optionally, a layer of nonwoven geotextile continuously bonded to the other side. The membrane can be used in vertical or horizontal applications, and is particularly useful for its stress-relief properties that resist crack formation and propagation in concrete walls and slabs in addition to serving as a barrier to moisture, toxic substances and insects. An appropriate composite membrane of the invention can be advantageously utilized in positive side, blindside, underslab or split slab applications. The thickness of the composite membrane preferably ranges from about 30 mils to about 150 mils.

Abstract: A roof ridge vent is formed with separation lines parallel with its outer edges which permit separation of the outer edge portions of the structure. In its original configuration, the roof vent structure may be used with wide cap shingles. Removal of the outer edge portions permits the ridge vent to be used in connection with narrower cap shingles.

Abstract: The disclosure relates to using metal acrylate compounds such as zinc diacrylate (ZDA), zinc dimethacrylate (ZDMA), among others for curing epoxy functional (and other cross-linking compounds), and to compositions containing such compounds for use in powder coat, film, adhesive, among other applications. ZDA and ZDMA containing compounds can cure the epoxy component of the compositions while being substantially free of conventional curing agents.

Abstract: An oxygen vending machine receives payment from a user. The payment is validated for appropriateness and sufficiency. If a valid payment is made, then concentrated oxygen is provided to a nipple or coupling located in an accessible place. In addition, a packaged breathing device, such as a nasal cannula, is dispensed. The user retrieves the packaged nasal device and uses it to direct the concentrated oxygen from the nipple into the user's nose or mouth. The user may select the particular breathing device which is to be dispensed. The flow of concentrated oxygen to the nipple is ceased after a predetermined period of time has passed.

Abstract: The components parts of a putter are weighted and assembled to form a putter in which the vertical center of mass lies within the horizontal length of a preferred striking surface on the face of the putter. Vertically mass balanced putters with flat bottom surfaces stand alone on the green without external support, permitting the golfer to view the geometric relationship of ball, cup, putter and topography of the green from various distances and perspectives. Distribution of mass of the putter equally on opposite sides of its vertical axis permits the putter to be swung in a pendulum motion without imparting yaw to the moving striking face of the putter.
