Abstract:
Disclosed in certain embodiments is a pressure sensing tube for transporting a material under pressure through a lumen and a pressure sensitive material associated with the tube and operable to change in appearance in response to a physical change in the tube caused by pressure within the lumen.A method of manufacturing a pressure sensing tube is also disclosed.
Abstract:
A hand-carried taping machine for taping an elongated object is disclosed. The machine includes a powered gear set operably coupled to a body and powered by a drive system. An applicator head includes a substantially C-shaped gear in meshing engagement with the powered gear set such that the substantially C-shaped gear rotates about an application axis under control of the drive system, and a tape reel mount for rotatably mounting a reel of tape on the substantially C-shaped gear for rotation about the application axis and application of the tape to the elongated object. A non-powered guide system operably couples to the body for guiding the applicator head along the elongated object with transient engagement with the elongated object such that the elongated object is maintained in a vicinity of the reel of tape.

Abstract:
A cable-wrapping apparatus is provided for applying cable (26) to a toroidal, non-cylindrically-shaped body (10) under uniform tension and with a uniform spacing. The machine includes a shuttle (20) rotatable about a transverse section of said body (10), which body is being rotated in a plane transverse to the plane of rotation of the shuttle (20). A compensating apparatus (44) is provided on the shuttle (20) and includes a profile follower roller (62) held in contact with the surface of the body (10) by centrifugal force created by the rotation of the shuttle (20). A compensator wheel (70) on the compensating apparatus (44) moves with the follower roller (62) to control storing of cable (26) during periods of low cable demand and paying out the stored cable (26) during periods of high cable demand.

PCT No. PCT/US79/00450 Sec. 371 Date June 26, 1979 Sec. 102(e) Date June 26, 1979 PCT Filed June 26, 1979 PCT Pub. No. WO81/00096 PCT Pub. Date Jan. 22, 1981A braking apparatus (36) is provided for a supply spool (30) whereby material (12) drawn from the spool (30) will have a relatively uniform tension. The braking apparatus (36) includes a follower roller (40) in contact with the material (12) on the spool (30) and a brake portion (38) in adjustably controlled braking contact with a brake rotor (102) mounted for rotation with the spool (30). The follower roller (40) follows the decrease in the diametral amount of material on the spool and simultaneously moves the brake portion (38) toward the center of the brake rotor (102) wherein a uniform braking force on the spool (30) is maintained. In one embodiment, the supply spool (30) is mounted on a shuttle (14) of a cable-winding apparatus so that as the shuttle (14) rotates, centrifugal force will act on the follower roller (40) to urge a roller (51) against the material (12) on the spool (30) and to move the brake portion (38) toward the center of the brake rotor (102) to maintain constant force on the material (12) being withdrawn from the spool (30 ).
Abstract:
Disclosed herein is apparatus for winding substantially inextensible flexible filament material or extensible flexible rubber material on and about the body of a toroidal member of oval cross-section (in this particular embodiment a disintegrable tire core). The apparatus includes rollers which support the toroidal member with the mid-circumferential plane thereof substantially vertical. The apparatus also includes a guide ring encircling the body of the toroidal member and supported in a substantially horizontal disposition. Drive means are included for rotating the guide ring about its axis and about the body of the toroidal member, meanwhile rotating the toroidal member about its axis, so that the toroidal member is advanced through the rotating guide ring. A supply of filament material is mounted on the guide ring to travel therewith, and extends to the surface of the toroidal member, so that such rotation of the guide ring and toroidal member as described above winds the filament material about and along the body of the toroidal member. In cooperation with such supply of filament material, means are included for providing relatively constant and even tensioning of the filament material being applied to the surface of the toroidal member, taking into account the oval cross-section of the toroidal member. A supply of extensible rubber material may be mounted on the guide ring to travel with the guide ring in place of the supply of the filament material. The rubber material extends from the supply to the surface of the toroidal member, so that rotation of the guide ring and toroidal member as described above winds the rubber material about and along the body of the toroidal member. In cooperation with such supply of rubber material, means are included for extending or stretching the rubber material continuously a substantially constant amount before it is supplied to the surface of the toroidal member, and depositing on said surface a substantially uniformly stretched material, taking into account the oval cross-section of the toroidal member. The support roller system, on which the toroidal member rotates, includes a bogey system to allow for change in the size of the toroidal member due to the wrapping of the materials thereon.
Abstract:
A method and apparatus for winding wire strands onto toroidal cores in which a length of wire is fed along a radially inwardly facing channel in an arcular guide to form a loop. As the leading end of the wire completes this loop it hugs the channel''s radial boundary to form a second loop inside the first as the wire feeding continues. A gap is provided in the radial boundary of the channel for receiving the core with the core''s central aperture in this gap so as each loop is formed the wire in that loop passes through the core. The upper and lower boundaries of the channel are spaced apart so as to maintain the loops in a single concentric layer around the guide and through the core. When enough wire has been fed the feeding is stopped, but the movement of the loops around the guide continues and winds (tightens) at least one new turn of wire onto the core for every complete circulation of the loops around the guide. Two or more wires can be wound onto a core at the same time with the method and apparatus according to the invention.
