Definitions

  • the present invention relates to articles having adjustable rigidity and/or cross-sectional area and articles and devices constructed from such articles.
  • Fig. 32 is partial cross section of the article of Fig. 33.
  • Fig. 78 is a partial cross-section of the device of Fig. 77 and a similar device.
  • Fig. 94 is a side schematic view of a device of the invention.
  • the spacer 460 Upon the application of pressure, from the bottom up or from the top down, the spacer 460 is compressed to allow the serrated or other high-friction surfaces to interact locking the elements together. This is one of many implementations of the telescoping concept as applied to non-rod-like situations.
  • Any friction-inducing or interlocking arrangement such as these could be made reversible or permanent in locking-structure.
  • solid 'mushroom- like' posts, or grain-elements were replaced by tufts of elastic fibers, or by solid mushrooms with tufts of elastic or wire-like fibers beneath the 'caps' of the mushroom-like elements, relatively irreversible friction-profiles might be achieved.
  • One part of the sequestered substance could be held apart by, say, ampoules or beads. This substance, when mixed with the first sequestered substance would cause the appropriate volume-increasing reaction. Blowing agents would be one example.
  • the second sequestered substance could be introduced by the intentional rupturing of beads or ampoules through physical pressure or applied energy. The specific case of such agents as are mentioned above is worthy of further mention. Small beads that are non-soluble in either material could be fitted with either:
  • a similar scheme could be implemented with the use of pure lithographic, or similar, etching or pitting techniques. If, say, a regular matrix of carbon-fiber, glass, or 5 similar threads were placed, as suggested, within a clear substrate of, for example, plastic sheeting, the pits could be engineered to gain strength from the regularly-spaced matrix of stiffening fibers. While each pit, and it's matching 'knob', plug, or shaft, could be made of the plastic sheeting material itself, what is suggested is more specific. The tips of the shafts and the rims or bases of the pits could be coated with substances having strong mutual o affinity. These substances might also be of an elastic and/or adhesive character.
  • the device is in the form generally of a hollow thread made with an external impervious skin.
  • any substance, structure or mechanism that can change volume, or effect a volume change in the o Controlled-diameter device device, even if the change is affected by altering the cross- sectional area of the controlled-diameter device. That is, even if the change is in localized areas which are contrived to drive the shift in diameter along the length of the 'thread'.
  • Inside this sequestered substance or mechanism there is an element capable of affecting this volume or area change.
  • the temperature of, and degree of, expansion might be regulated directly.
  • a black- surfaced thread might absorb sufficient heat to cause a linear closure of the space between threads to regulate the amount of sunlight passed through a fabric. In this way, a pre-calibrated sun-control film might be created.
  • the fibers might be, for example, etched from silicon and mounted to the main body of the silicon wafer, or etched assembly at one end.
  • a series of fibers would be manufactured of increasing/decreasing length, width, thickness, and/or rigidity in such a way as to cause each element to have a descending/ascending 'free-air' resonant frequency.
  • Each element so 0 crafted would be housed in a cavity or gap across which electro-static, electrical, magnetic, acoustic, or electromagnetic fields might be applied to the fiber-bearing region. The methods are well established.
  • a fabric-like composite material 1030 having a porous barrier sheet 1035, an open cell foam layer 1040, preferably very soft, a hydrophilic layer 1045, a non- hydrophilic layer 1050 (those two layers being the active layers), and a barrier layer 1055 which may be woven.
  • Layers 1035, 1040 and 1055 are protective layers.
  • a suitable controller receives the conductors from opposite ends of the control circuit of the sheet assembly in such as way as to allow the sensing of the impedance of the final thread-like element(s) to be controlled.
  • the controller then automatically adjusts the drive voltage and/or current that will be potentially supplied to the devices to effect state-change.
  • the controller is fitted with inputs whereby to control the drive voltage/current supplied across the 'fabric' (after the normal range of values has been established by the feedback and calibration just described). These inputs might be fed by a hand-held controller or by an automated source.
  • Synthetically-created plastic, cellulose, or other suitable hydrocarbon 'popcorn' is one variant of this.
  • a compressed sponge-like or fibrous element and/or viscous liquid or slurry is mixed with water or solvent in very small quantities such that the liquid, sponge, or slurry is mobile and mutable until the water/solvent evaporates or departs.
  • Additional water/solvent may be encapsulated at the center of the larger capsule, or otherwise aggregated mass, in such a way that its sudden release both disperses the surrounding mutable materials and shatters any bonds, adhesions, or encapsulation of that surrounding material.

Abstract

L'invention concerne des articles au diamètre réglable et à rigidité réglable. Les articles à rigidité réglable peuvent comprendre des articles (180) possédant des surfaces de contact n'étant touchées qu'avec l'expansion d'un élément (175) de l'article. Des tubes, pourvus de tiges allongées flexibles avec des surfaces de frottement, sont flexibles lorsque les tiges sont libres de mouvement les unes par rapport aux autres et rigides lorsque les tiges sont immobiles les unes par rapport aux autres, par pression, au moyen d'adhésifs ou d'autres techniques. Les tubes au diamètre réglable sont pourvus de mécanismes d'expansion internes tels que des poches contenant une matière gonflant à la chaleur, et d'une source de chaleur, ou d'actionneurs bimétalliques réagissant à l'exposition à la chaleur.
