Abstract: A subsea buoy comprises a rigid watertight external shell extending continuously around a supporting internal structure that is sealed and fully enclosed by the shell. The shell is formed integrally and simultaneously with the internal structure by the same additive manufacturing process. The internal structure comprises cavities disposed between structural members, such as struts of a lattice or webs of a matrix. The structural members and cavities can be in a hierarchical or fractal array comprising a relatively narrow outer tier adjoining the shell and at least one relatively wide inner tier within the outer tier.

Abstract: Structures designed to mitigate implosion pressure spikes through the use of an external sacrificial confining structure. Such improved structures can, in some embodiments, completely surround the existing structures that are at a high risk of imploding. The improved structures can slow the rate at which the surrounding fluid media volume is consumed by providing resistance to flow into the enclosure.

Abstract: A method for manufacturing a plastic bowling pin that has a porous core and a resilient envelope includes the step of blow-forming the envelope in a blowing mold and removing the envelope from the blowing mold. The envelope is then cooled to a temperature of 60.degree. C. to 100.degree. C. A core plastic material containing an exothermic agent is then injected into the envelope for forming the core. The core plastic material is heated to a temperature of 200.degree. C. to 260.degree. C. The inner layer of the envelope is thus fused to the plastic material of the core to provide an intimate connection between the envelope and the core.

Abstract: A bowling pin has a pin body with a head and a magnet, at least partially enclosed in a plastic envelope, positioned in the head for manipulating the bowling pin. The plastic envelope and the head are fused to one another by rotating the plastic envelope within a cutout of the head so that the contact surfaces are heated for softening and fusing the material.

Abstract: The base structure of a bowling pin having an aperture at the center of the base portion thereof for the engagement with the bottom portion of the core of the bowling pin, characterized in that an inner wall is circumferentially provided around the aperture and an outer wall is provided concentrically adjacent to the inner wall, and a circular slot is formed by the inner wall and the outer wall; the outer surface of the outer wall is provided with a plurality of screw threads and at least a pair of transverse hole are provided perpendicular to the circular slot so that the outer surface of the outer wall communicates with the circular slot, whereby a resin solution covers the plurality of the screw threads and flows into the slot, and forms a compact base structure.

Abstract: A magnetically responsive bowling pin having a first upwardly open cavity in its head portion and a second elongated cavity smaller and cross-section and extending downwardly in the head portion of a bowling pin. The first cavity receives a plastic cap having a top portion and a skirt with a permanent magnet and a plastic plug disposed in press fit engagement within the skirt. The skirt in turn is in press fit engagement with the wall of the first cavity to retain the assembled magnet and plastic parts in the desired position in the cavity. The second elongated cavity serves to remove material from the body of the bowling pin and thus compensates for the added weight of the permanent magnet and the slight additional weight of the plastic cap and plastic plug. As a result, the desired weight, weight distribution and balance of the bowling pin is not disturbed.

Abstract: A plastic pin having a porous and/or cellular core that is surrounded by a hard shell. To be able to influence the level of the center of gravity of the pin, the shell is provided with an aperture in which is secured an insert in the form of a hollow body that extends into the interior of the shell and is disposed coaxially thereto. The hollow body can extend from the head of the pin beyond the neck and into the upper portion of the barrel portion of the pin.

Abstract: An elongated member, for example, a bowling pin, has a core of foamed plastic material, which has areas of greater density, generally toward the lower end of the bowling pin, so as to provide desired weight distribution along the member. In the bowling pin, providing a denser core area near the bottom lowers the center of gravity. In a baseball bat, the increased density can be provided in the "sweet spot" area, if desired.In producing the variation in density, the mold in which the foamed core is formed is heated in those areas in which the density is to be light and chilled in those areas in which the density is to be increased.In making a baseball or softball bat, a foamed core can be wrapped directly with graphite filament or graphite and glass filaments, or synthetic fibers such as Aramid fibers of the type marketed by Dupont de Nemours as KEVLAR.RTM. either dry wrapped and subsequently embedded in epoxy or the like, or wrapped with adhesive coated fiber that is then cured.

Abstract: A bowling pin for use with an automatic scorer includes a wood core and an ionomer cladding having an outer surface which surrounds the standing portion of the pin. The pin includes a first fluorescent coating on the outer surface in a preselected area, preferably in the neck portion of the pin. This first fluorescent coating emits a relatively high level of visible light when subjected to ultraviolet light. A second fluorescent coating, which is colorless under ambient light, covers the standing portion of the pin, including the first fluorescent coating and emits a relatively low level of visible light, i.e., the moonglow effect. The second coating also allows the relatively high-intensity visible light which is emitted from the first fluorescent coating to pass therethrough for detection by an automatic scorer.

Abstract: A plastic pin, such as a bowling pin, for bowling lanes. The pin has a hard shell that surrounds a core of cellular and/or porous material, preferably a thermoplastic material. The interior of the shell has at least one partition that divides the hollow interior of the shell.

Abstract: A plastic pin, including a bowling pin, for bowling lanes, and a method of making the same. The pin has a hard shell that surrounds a core of cellular and/or porous material. The shell has a lower bulging portion, thereabove a neck-like reduced diameter portion and thereabove an again slightly wider head. The shell has a wall thickness that from the greatest diameter part of the bulging portion increases gradually both upwardly toward the reduced diameter portion and downwardly toward a base of the pin. The plastic for the core of the pin is introduced into the hollow interior of the shell and fills at least a portion thereof by expansion. The core plastic is introduced at such a temperature that an inner surface of the plastic shell is softened at least at some locations by contact with the introduced core plastic to thereby effect fusion between the plastic of the shell and the introduced core plastic.
