Abstract: The present invention relates to methods for the controlled placement of a curable, shear thinnable polymer composition into a porous web. The controlled placement is performed by applying tension to the porous web. The polymer composition is applied onto a surface of the web. The composition is shear thinned sufficiently to reduce its viscosity and selectively place it into the tensioned web to encapsulate at least some of the structural elements of the web, leaving most of the interstitial spaces of the porous web open. The invention also relates to methods for selectively placing the polymer composition in a substantially continuous region extending through the web so that the polymer composition fills the interstitial spaces and adheres adjacent structural elements in the region. In the areas in the web above and below the filled region, at least some of the structural elements are encapsulated and most of the interstitial spaces are open.

Abstract: Improved processes are provided for treating a porous substrate (especially a fabric) to produce novel internally coated porous materials. During treatment, a curable thixotropic material and one or modifying materials are applied to the porous substrate as an impregnant. The treatment imparts specific properties to the end product material. Selection of the modifier material is based on the particular end use application. Sufficient energy is directed to the impregnant and porous substrate to cause the impregnant to flow into the porous substrate and force the modifier to specific positions within the substrate.

Abstract: An improved process is provided for treating a porous web (especially fabric) to produce a novel silicone polymer internally coated web. In the process, a starting curable liquid silicone polymer is coated under pressure upon one surface of the web, and the web is then subjected to localized shear forces sufficient to move the silicone polymer composition into interior portions of the web and to distribute the silicone polymer composition generally uniformly therwithin in such planar region. Excess silicone polymer composition is wiped away from a web surface. Thereafter, the resulting web is heated or irradiated to cure the silicone polymer. Preferably a web is preliminarily impregnated with a fluorochemical. Webs procuded by this process are breathable, waterproof or highly water repellent, and flexible.

Abstract: An overlay of sheet material that is impregnated with thermosetting resin--typically a fabric of a type including metallic, synthetic fiber, natural fiber and ceramic cloths impregnated with epoxy resin--is wrapped about or laid on an underlay of material that is also impregnated with thermosetting resin--typically a resin material reinforced with fibers of the graphite, glass, aramid, or ceramic types. The overlay and underlay are cured under heat and pressure in an oven at the same time, causing cohesive bonding of the resin within each. The resin exudes through the fabric overlay during curing and forms a hard transparent shell of cured resin to the composite article. The embedded sheet material selectively imparts color, pattern, texture, reflectivity, penetration resistance, tensile strength, thermal and electrical conductivity, and other visual and mechanical properties to the composite article as desired.

Abstract: A safety razor which conforms to both concave and convex body surfaces and has a handle and a curved rotatable cartridge. Shaving blades are positioned on both sides of the curved cartridge, thus, both concave and convex accurate cutting edges are obtained in a single compact cartridge. The concave surface is used when shaving convex body surfaces. Rotating the cartridge 180 degrees exposes the convex cutting surface for shaving concave body surfaces. The cartridge is rotatably mounted to the handle and is held in either concave or convex shaving positions with detents. When the alternate shaving position is desired, the cartridge is rotated 180 degrees, either manually or remotely using a push button device within the handle, which is also disclosed. The correct angular relationship of the handle to the cutting surface of the cartridge is set and maintained for both concave and convex settings by means of the detents since the amount of rotation between the two shaving settings is 180 degrees.

Abstract: A machine applies a cyclic localized thrusting force against the back of a patient recumbent upon his or her back on a support bed in order to manipulate the user's back or spine. Several (typically three) spaced-apart thruster members reciprocate between a first position retracted into the support bed below its top surface and a second position thrusting into pressured contact with the patient's back. The reciprocal thrusting is variable and controllable in real time with respect to the locations, area, patterns of contact, amplitude, frequency, numbers of cycles, pressure, and number of separate sites. Spinal therapy normally performed by a human therapist may correspondingly be comprehensively mechanically replicated.

Abstract: An apparatus is described for decompressing the spine from a seated position while permitting leg exercises. Two triangular sides have forearm supports which can be set at an angle to the horizontal plane with the angle having a range of 20.degree.-45.degree.. The triangular sides are attached through cross members and have hand grips mounted adjacent the forearm supports. The apparatus rests on a floor, the ground, a chair or similar subsurface. The user positions himself in a seated position between the sides and raises his body by pressing downward with his forearms and hands, thus unloading and decompressing the spine and lumbar back. An optional harness suspended from above the person may be used to maintain continuous decompression of the lower spine between the upward movements executed by the user, or lower body restraints may be used to permit decompression of only the upper spine.
