    • The present invention provides a means of easily attaching and detaching a member that reinforces an envelope of a balloon to and from the envelope. Balloon 1 according to an embodiment of the present invention comprises Inner Member 121 and Outer Member 123. Each of Inner Member 121 and Outer Member 123 is a disk-shaped member made of a plastic, a light metal, or other lightweight material. Inner Member 121 and Outer Member 123 are attached to Envelope 11 by tightening Bolts 125 and Nuts 126, with Envelope 11 therebetween. A donut-shaped Rubber Seal 122 is located on the surface of Inner Member 121 in contact with Envelope 11, and a donut-shaped Rubber Seal 124 is located on the surface of Outer Member 123 in contact with Envelope 11. Rubber Seal 122 and Rubber Seal 124 are pressed tightly against Envelope 11 as Bolts 125 and Nuts 126 are tightened, and Holes H2 provided in Envelope 11 to accommodate Bolts 125 are sealed.

    • This Application seeks to protect Applicant's HYTORC® Z® System which involves: tools having multi-speed/multi-torque modes with torque multiplication and vibration mechanisms without use of external reaction abutments; a force transfer means to yield in-line co-axial action and reaction for use with such tools; driving means and shifting means capable of attaching to washers under the nut for use with such tools and force transfer means; associated washers and fasteners for use with such tools, force transfer means and driving means; and related accessories for use with such tools, force transfer means, driving means, washers and fasteners. The HYTORC® Z® System includes the following: Z® Washers located under nuts or bolt heads of various types having engageable perimeters of multiple shapes, sizes, geometries and serrations, such as washer/fastener radius engagement differentials, and frictionally biased faces with relatively higher friction against the flange surface and relatively lower friction against the nut, such as friction coefficient increasing treatment means of various types, sizes and locations; HYTORC Z® Guns incorporating a powerful intermittent (impact, vibration, ultrasonic, etc.) mechanism, a precise torque multiplier in the same tool combining rapid run-down with calibrated torque; HYTORC® Z® Sockets with dual drive coaxial action and reaction having outer sleeves to react on Z® Washers and an inner sleeves to turn nuts or bolt heads; HYTORC® Z® Spline Adapters and Reaction Plates for backwards compatibility with HYTORC®'s torque/tension systems including the AVANTI® and ICE® square drive systems, the STEALTH® limited clearance system, the pneumatic jGUN® series, the FLASH® Gun and LITHIUM Series electric multipliers and more; the combination of HYTORC Z® Washer and the HYTORC® Z® Dual Friction Washer™ including a dual friction-enhanced face washer and/or the HYTORC® Z® Nut/Bolt for counter-torque under a nut or bolt head on the other side of the joint; HYTORC® Z® Dual Drive Offset Links for tight clearances while using HYTORC®'s torque/tension systems; HYTORC® Z® Vibration Mechanisms applied thereof; Z®-Squirter® Washers; Z®-DTI Washers; HYTORC® Z® Washer and Nut Assemblies; Anti-Loosening Z® Washers; and any combinations thereof. Further disclosures include: Tapered Fastener Assemblies; Tapered Torsional Couplings; Two-Part Tapered Nut Assemblies; Two-Part Tapered Thread Nut Assemblies; HYTORC® Anti-Loosening Z® Washers, Nuts and SMARTSTUDS; and any combinations thereof.
