摘要:
A tightly bonded abrasion resistant surface layer is formed on, or a binding layer is formed therebetween, reactive metal or metal alloy substrates. A powdered mixture of oxides, at least one of the oxides having a heat of oxidation lower than the heat of oxidation of the oxide of the substrate, is disposed on the substrate. The substrate with the oxide powder disposed thereon is heated to a temperature lower than the melting point or solidus temperature of the substrate. The powdered mixture of oxides preferably comprises fly ash. An abrasion resistant surface layer may be bonded to a structural part by mixing the powdered mixture of oxides with powdered reactive metal or reactive metal alloy, disposing the resultant mixture on the part, and heating.

An artificial fishing lure is disclosed having a main body with a streamer detachably connected thereto. The body is cast from a weighted material such as lead with an open cavity and the locking portion of a clasp formed in the rear portion thereof. A wire bail is pivotally attached to said body, overlies a portion thereof and is received in said locking portion, whereby said bail, said body and said locking portion cooperate to define a clasp assembly on said body. The clasp assembly as formed is then used to detachably secure said streamer to said body to provide a universally adaptable fishing lure.
摘要:
A method of forming filaments, particularly continuous strips, sheets or the like, by rotating a chill wheel against a meniscus of molten material formed about the periphery of an elongate orifice through which the molten material is fed under uniform fluid pressure along the longitudinal axis of the orifice. Filaments of different widths, thicknesses and composite structures are extracted by utilizing single or plural chill wheels in conjunction with plural orifices.
摘要:
A method and apparatus for producing filamentary articles from an open bath of molten material. A quench wheel having a peripheral chill surface is rotated upon the surface of a portion of the bath provided with a baffle that defines a puddle of molten material free from fluid turbulence, thereby permitting high production rates and precise control of product configuration.

An improved net for covering the head of a lacrosse net. The net is formed of a flexible web made of a non-plastically deformable material having preformed interstices whose size varies in a predetermined manner. A catching or pocket region is formed in the web by having large size interstices in a region centered on the longitudinal axis of the web. The size of the interstices becomes smaller as the distance from the center region increases. When the web is attached to the head of a lacrosse stick, the center region is automatically deformed by a lacrosse ball to form a pocket. The need for a user of the stick to form or shape the pocket before using the stick is eliminated. Also, the position of the pocket with respect to the head is adjustable by moving the web longitudinally before affixing the web to the head. The depth of the pocket is adjustable by varying the amount of web material connected between side walls of the head. A throwing region in the web is formed by an area of the web having relatively small size interstices.The web is affixed to the head in such manner that the transverse tension on the web in the throwing region is greater than the transverse tension in the catching region.
摘要:
A fishing lure includes a weighted head portion having a rounded front surface, an artificial grub worm attached to the head portion adjacent the lower end thereof, an attachment eye on the upper end of the head portion for attaching a fishing line thereto, a fish hook attached to the attaching eye and extending angularly downwardly and rearwardly to the grub worm, and a counterweight assembly extending upwardly from the upper end of the head portion. The lure is adapted to be utilized in a fishing technique wherein it is bounced along the bottom of a body of water and it is adapted so that when it comes to rest on the bottom it normally rests on the rounded front surface of the head portion in order to prevent the lure from becoming snagged or caught on debris, or other structures on the bottom.

A fish hook includes integrally connected hook, shank and eyelet portions which are formed to both increase fish catching efficiency and to minimize damage to hooked fish so that fish can normally be released essentialy unharmed. The eyelet portion is substantially aligned with the tip of the hook portion so that the tip can more effectively penetrate the jaw structures of fish, and the shank is bent outwardly from the hook portion to provide clearance around the jaw structures of fish. The overall construction of the hook and shank portions normally prevents the hook from passing into the inner mouth areas of fish in order to avoid causing serious damage to the fish.
