  • Patent number: 5383894
    Abstract: A compression device for applying compressive pressures against a patient's limb through means of a flexible, pressurizable sleeve which encloses a limb. The compression device has a pressure control apparatus which includes a microprocessor, a driver circuit and a flow control valve having a stepper motor attached thereto. The microprocessor is programmed to control pressure to the sleeve in conjunction with the driver circuit and the flow control valve by actuating the stepper motor. The microprocessor compares a signal generated by a pressure transducer to a preselected pressure value, it then generates an electrical signal to a driver circuit which in turn sends pulses to the stepper motor to automatically adjust the flow control valve, thus, controlling the flow of fluid therethrough so as to maintain a preselected pressure applied to the limb by the pressure chamber of the sleeve.

  • Patent number: 4834127
    Abstract: A cane handle is provided with a novel fastenerless lock for securing the handle to a tubular shaft to form a cane assembly. The fastenerless lock includes a depending stub shaft formed integrally with the handle, that stub shaft having a series of annular lock flanges oriented generally normally to the stub shafts' longitudinal axis. The lock flanges are deformable and have an outside diameter in their undeformed, pre-assembly state, that is slightly greater than that of the inside diameter of the tubular shaft into which the stub shaft bearing the lock flanges is inserted to form a cane assembly. Upon insertion into the tubular shaft, the flanges are deformed upwardly in generally dish shaped configuration that resists their subsequent withdrawal.

  • Patent number: 4341213
    Abstract: Nonwoven fabrics are bonded by a binding agent which comprises an aqueous dispersion of an organic polymer coupled to an inorganic filler by means of an organosilane or organotitanate coupling agent. Such fabrics possess properties which render them exceptionally suitable for use as top sheets for disposable diapers and the like.

  • Patent number: 4303724
    Abstract: The tear properties of flexible adhesive tapes comprising a pliable base and a low-count open meshed fabric adhered thereto by a layer of adhesive are improved by the use of so-called texturized or false-twist yarns in the filling of the fabric.

  • Patent number: 4173131
    Abstract: A lightweight, porous knitted elastic bandage is produced from a warp of false-twist synthetic yarns with a filling inlay of regular yarns. The filling yarns are arranged in varying patterns across the warp yarns so that a portion of their length lies in looped and cursive configuration upon the surface of the bandage, and the structure is so open that overlapping layers of the bandage cling to each other in substantially non-displaceable relationship.

  • Patent number: 4064091
    Abstract: A novel class of monomeric emulsion stabilizers consists of certain types of ethylenically unsaturated radicals covalently linked to a quaternary nitrogen atom which in turn is covalently linked to a lipophilic radical. Such monomers will polymerize with other ethylenically unsaturated radicals forming self-stabilized, surfactant-free polymeric dispersions.
