摘要： An apparatus (10, 110) and method to form a workpiece (32, 132) into a useful product (28, 128) using a pressurized fluid (14), also termed as “hydroforming”. The workpiece may be a tube or may be one or a plurality of sheets of a material. The apparatus has a chamber (12) adapted to contain a quantity of a fluid, a hydroforming means positioned within the chamber, and means for substantially immersing the workpiece in the fluid before, during and after the hydroforming operation. Dies (16, 18) enclose the workpiece and provide a cavity of desired shape against which the workpiece is expanded by the pressurized fluid. The chamber may be open or closed to the atmosphere during operation and the fluid temperature and/or level may be controlled.

摘要： A carrying bag accessory featuring a mat that is externally affixed to a bag or any variant bag designs such as a gym bag, duffle bag, rucksack, backpack, etc., and conveniently stored in a folded configuration when not in use and deployed in an unfolded configuration adjacent to the bag when in use to provide a flat clean surface upon which a user can rest or place items on. The mat is comprised of a multiplicity of rigid or semi-rigid hinged panels carefully configured to fold in such a manner as to preserve the cleanliness of surfaces that come into contact with the user. The mat is retained in a folded configuration by means of magnetic or other types of fasteners allowing the deployment and storage of the mat by the user with minimal contact and effort.
摘要翻译：一种携带袋配件，其特征在于外部固定在袋子上的垫子或任何变体袋设计，例如健身包，马桶，背包，背包等，并且在不使用时方便地存储在折叠构型中，并部署在在使用时邻近袋子的展开构造提供平坦的清洁表面，用户可以在该平坦的清洁表面上休息或放置物品。垫子由许多刚性或半刚性的铰链板组成，其被仔细地构造成以保持与使用者接触的表面的清洁度的方式折叠。垫子通过磁性或其他类型的紧固件保持在折叠构型中，允许用户以最小的接触和努力部署和储存垫子。

摘要： A soft goods type foldable, wrappable sleeve orthopedic cast immobilizes and conforms to the shape and configuration of a limb, or other part of the anatomy. The soft-goods type cast assembly is initially specially formed or configured to specifically fit a selected portion of the anatomy of a patient. The cast conforms to the anatomy through the use of airtight and moisture-proof pouches which encapsulate either (1) open cell or fiberglass matrices impregnated with a water-activated hardenable pre-polymer, or (2) the entire assembly. After the tightening of the cast around the limb, the application of water activates the urethane polymer which conforms to the configuration of the limb encased. Supplemental bendable ribs may be employed to splint the limb prior to activation of the hardenable material. The soft goods type cast is held in place by straps, and may be removed or adjusted by releasing or tightening the straps. The splinting elements may be removed and replaced. An inlet duct may have a capsule in it with some of the chemical material which aids in polymerization of the urethane. A venting duct may also be provided to permit the escape of air or gases. The water activated pre-polymer material may include two isocyanate pre-polymers of significantly different viscosities and equivalent weights.
摘要翻译：柔软的货物类型可折叠，可包装的袖口矫形器固定并符合肢体或解剖结构的其他部分的形状和构型。软货物铸造组件最初被特别地形成或构造成特别地适合患者的解剖结构的选定部分。铸件通过使用气密和防潮袋，符合解剖学，其中包括（1）用水激活的可硬化预聚物浸渍的开孔或玻璃纤维基体，或（2）整个组件。在围绕肢体收紧铸件之后，水的使用激活了符合肢体包裹构型的聚氨酯聚合物。可补充的可弯曲肋条可在活化可硬化材料之前夹住肢体。软质铸件通过带子固定在适当位置，可以通过松开或拉紧带子来移除或调整。可以去除和更换夹板元件。入口管道可以在其中具有胶囊，其中一些化学材料有助于聚氨酯的聚合。还可以设置排气管以允许空气或气体逸出。水活化的预聚物材料可以包括具有显着不同粘度和当量重量的两种异氰酸酯预聚物。
