Abstract:
A method of manufacturing angiographic catheters comprises providing (1) a length of elastomeric tube of a predetermined outer diameter and braiding (2) multiple strands of wire wrapping about its exterior. A plastic bonding agent is extruded (3) onto selected areas or onto the entire length of the wire wrapping to bond the strands to each other. Thereafter, the wire wrapping is ground away (4) at predetermined spaced locations along the length of the elastomeric tube to provide a series of wire wrapped sections joined by non-wrapped sections. An elastomer layer is disposed (5) over both the wire wrapped sections and the non-wrapped sections throughout the length thereof. Subsequently, the coated length is severed into pieces with the pieces each constituting unitary construction including a wire wrapped section that forms a catheter body and a non-wrapped section joined to at least one end thereof to constitute a flexible catheter tip. The angiographic catheters formed thereby include a main body portion provided with wire braiding reinforcement and a soft flexible tip portion (39, 50) having no wire braiding disposed therein.
Abstract:
An easily disassembled, rugged stand for supporting musical instruments does not require moving parts, hinges, or screws. The stand is made of two similar interlocking supports (10, 20), a cap (30) and a removable, flexible strap. The supports are adapted to be fastened together and contain the cap when the stand is disassembled. Further, the flexible strap may be fastened to the supports and used as a handle (40). When the stand is assembled, the supports are further stabilized by the cap (30), and the flexible strap (40) may be attached to the cap (30) and used to hold, for example the neck of a guitar.
Abstract:
A method of manufacturing a component formed of parts capable of being separated for reassembly around another component. The process starts by taking separated, e.g., rod (3) and cap (5), forgings and coining or forging them together prior to machining. The mating surfaces of the forgings are formed with a ridge-groove or a dimple/lug-recess configuration giving them a self-locating ability. After machining, the forgings are fractured along the original division to obtain two uniquely matched surfaces that need no further processing before being reassembled, e.g, to form a connecting rod for an internal combustion engine.

Abstract:
A method of manufacturing a component formed of parts capable of being separated for reassembly around another component. The process starts by taking separate, e.g., rod (3, 3') and cap (5, 5') forgings and coining or forging them together prior to machining. The mating surfaces of the forgings are formed with a ridge-groove (9) or a dimple/lug-recess (12) configuration giving them a self-locating ability. After machining, the forgings are fractured along the original division to obtain two uniquely matched surfaces that need no further processing before being reassembled, e.g., to form a connecting rod for an internal combustion engine.

Abstract:
In a dead axle wheel assembly (2) having a hub (6) and bearings (8) mounted on a threaded spindle (10) and held there by lock nuts (16) to rotatably support a vehicle wheel, a safety lock (4) comprising a sleeve (26), closed at an outer end and open at an inner end, the sleeve (26) of a size, when in position secured to the spindle (10), to sit on and cover the outer end of the spindle (10) with the sleeve's (26) inner end spaced from it the lock nuts (16), and means associated with the closed end of the sleeve (26) to secure the sleeve to the other end of the spindle (10), whereby, when in position on the spindle (10), the inner end of the sleeve (26) is located to obstruct the lock nuts (16), if they become loosened, to keep them from disassociating from the spindle (10). This safety lock (4) provides a simple but effective construction for maintaining the integrity of a dead axle wheel assembly.
