Abstract: An insulated exhaust pipe comprising inner and outer spaced corrugated metallic tubes separated by refractory fiber isulation. Strips of higher density refractory fiber insulation hold the low density insulation in place during operation and prevent degradation of the fiber by vibration. The pipe is made by rolling the inner tube over a layer of insulation, including strips, to which adhesive has been applied. The insulated tube is then inserted into the outer tube, rotating the insulated tube so that the corrugations of the outer tube do not damage the insulation. Specific structure for carrying out these method steps is disclosed.

Abstract: A cordless electric fishing reel is set forth wherein a conventional fishing pole includes an elongate, hollow handle mounted rearwardly of a fixedly secured fishing reel. The handle includes a self-contained battery pack aligned with an electric motor wherein the electric motor is cooperative with plural sets of planetary gears wich an output shaft of the planetary gear arrangement directed and aligned with a ratchet mechanism. The ratchet mechanism is operative for engagement interiorly of a ratchet sleeve to engage and drive the associated reel for rewinding of the fishing line associated with the reel. A pivotally mounted switch mounted on the handle is formed with a medial bore for receiving in a non-binding manner the output of the planetary gear arrangement with an electrical contact arrangement positioned at a lowermost end of the switch for selectively energizing the motor.

Abstract: In a film cassette, a spool core is supported for rotation in an unwinding direction to thrust a leader section of a film roll coiled about the spool core to the exterior of the cassette and in a winding direction to return the leader to the interior of the cassette. A pair of flanges are arranged in spaced relation along the spool core to radially confine the leader. The flanges are adapted to be flexed apart to permit the leader to readily escape the confinement of the flanges when the spool core is rotated in the unwinding direction. According to the invention, the leader has respective edge portions for flexing the flanges apart in succession when the spool core is rotated in the unwinding direction, whereby the leader can more easily overcome any resistance the flanges may present to movement of the leader outwardly of the flanges.

Abstract: A continuous winder for web material includes two pairs of turret arms mounted for rotation with respect to each other on a common axis, and also includes a lay-on roll mounted for lateral movement toward and away from the axis of the turret arms. The lay-on roll maintains pressure engagement with the winding roll until the interval of actual roll changing, when it moves from the wound roll into pressure engagement with the new core with the web running therebetween, whereupon the web is cut between the two rolls to complete the roll change.

Abstract: A tape reel is described which is a one-piece, integrally, molded member. A planar continuous flange is connected to a central hub. A plurality of petals or ears is molded in an upright condition to be movably connected to the upper end of the hub. The ears are pushed down to be parallel with the plane of the lower flange to receive tape. The ears are held in place by cooperating members formed on both the ears and hub. Finally, a friction button can be formed separately and assembled on the hub, or may be integrally molded of the hub.

Abstract: An expansible reel is provided having a plurality of rigid structural mems parallel to each other and to a central axis of the reel, joined at the ends to supports allowing small radial displacements of the members. Between contiguous rigid members there are placed inflatable members into which compressed air is introduced to space apart the rigid members when an optical fibre wound around the reel is to be submitted to tests under controlled tensile stress conditions.

Abstract: Two coupling pawls are mounted eccentrically and pivotably in their center of gravity on a drive pulley of the tightening rotary drive. A coupling ring is non-rotatably connected to the belt coiling shaft of the belt retractor. The coupling ring comprises an internal toothing into which the coupling pawls are driven solely by the action of inertia forces to establish a coupling connection. The coupling pawls are offset in the peripheral direction with respect to each other by an angle which corresponds to an odd multiple of half the pitch of the internal toothing of the coupling ring.

Abstract: A safety belt retractor is provided with a dual-tension comfort function. Between the belt reel and housing a retractor spring and an auxiliary spring of weaker spring force than said retractor spring are connected functionally in series via a ratchet wheel. The rotation of said ratchet wheel is selectively blockable by a pawl. The transition between diminished and undiminished tension in the webbing takes place gently, jerk-free and silently because the rotation of the ratchet wheel is inhibited by a brake means as long as the auxiliary spring is not completely or at least almost completely tensioned. Said brake means includes lever-like engagement elements which are pivotally mounted on the ratchet wheel and which are moved by the pressure exerted by the outer periphery of the auxiliary spring in the axial direction to activate a friction brake.

Abstract: A light-tight cassette, and method of making same, for enclosing and dispensing a roll of photosensitive web material. The cassette comprises a folded fiberboard housing having a plurality of housing wall portions with oppositely projecting lateral edges which define opposite sides of the housing. The plurality includes two planar wall portions that extend perpendicularly to each other to respective ends thereof which are disposed in spaced alignment to provide an opening between them. Two extruded plastic light-locking members are attached to those wall portion ends, respectively, one such member extending across the opening toward the other member to form a web exit passageway therebetween. The one member includes a resiliently flexible, inwardly projecting cantilever portion that is biased toward an opposing portion of the other member, both such portions having light-locking material thereon.

Abstract: A spool (10) has a first elongate slot (22) in an outer surface (12) of the spool (10) core for receiving an end portion (14a) of a strip (14) of web material, such as a strip of photographic film. The core surface has another elongate slot (24) for receiving the flange (26b) of a clip (26) used for retaining the web material on the spool. The clip has a semi-cylindrical portion (26a) that surrounds the spool core and holds part of the web material against the core surface.

Abstract: An insole (10) for athletic shoes and the like. A first layer (12) of the insole is suitable for disposition toward a user's foot. A second molded layer (14) is comprised of a visco-elastic material. The visco-elastic material typically comprises a plasticizer, and, in minor portion, a resin material, and has the ability to flow, upon exertion of a force thereon, with sufficient elasticity to resume its original shape upon removal of the force. The second layer comprises a lower surface comprising recesses which make up less than 20% of the exterior surface in the absence of deforming forces. The recessed areas function to receive adjacent material of the second layer upon application of pressure representative of the presssure applied by the human foot. A third optional layer (16) of a foamed plastic material may be interposed between the first and second layers.
