Abstract: A medical aid that functions as (1) a standalone femur traction device for femur traction or (2) a trapezoidally-shaped cushioned leg support pillow. The medical aid can be placed on an ordinary bed and is constructed to provide traction without the use of weights or pulleys. The medical aid includes a base that supports a trapezoidally-shaped leg pillow or support and an adjustable U-shaped fulcrum coupled to the base. The U-shaped fulcrum supports thereon an elastic cord with an attached leg pin connector. Adjustment of the U-shaped fulcrum and/or the tension applied by the elastic cord varies the amount of traction. The trapezoidally-shaped cushioned leg support can be used with or without the base.

Abstract: A method of packaging compressible insulation material includes feeding insulation material into contact with a mandrel, rolling up the insulation material on the mandrel to form an insulation roll, applying pressure on the insulation material, during the rolling of the insulation material, with a pair of opposed belts which are adapted to contact the roll being formed with an increasing area of contact as the diameter of the roll increases, and increasing tension on the belts as the diameter of the roll increases in order to maintain a substantially constant pressure on the insulation material.

Abstract: A method for collecting long glass fibers produces substantial lattice uniformity, eliminates the need for binder, and results in a generally rectangular wool pack which displays significant compressibility and recovery desired for commercial products. Generally spiral flow of fibers in the veil is captured on collecting conveyors and conveyed through direct forming apparatus with generally minimal disturbance of the spiral relationship between glass fibers. Further, a system is disclosed for producing wool insulation products of long glass fibers in accordance with the method. The principles and practices of the method and system may further be employed with short fibers to produce a wool pack of generally oriented short fibers.

Abstract: A method for manufacturing a mineral fiber product includes establishing a stream of mineral fibers, directing polymeric fibers toward the stream of mineral fibers to cause intermingling of the polymeric material, and applying heat to the polymer fibers so that some of them become softened to the extent that they lose their fibrous form and become attached to the mineral fibers as non-fibrous particles, whereas some of the polymer fibers retain their fibrous form.

Abstract: A method for manufacturing a mineral fiber product includes centrifuging mineral fibers with a spinner, forming a veil of the mineral fibers moving in the direction of the axis of the spinner, directing toward the veil, from a position within the veil, organic material to cause intermingling of the organic material and the mineral fibers, and, collecting the intermingled organic material and mineral fibers to form a mineral fiber product.

Abstract: An insulation assembly and method of making is disclosed. A fiber pack is engaged along its side edges to tuck the fibers inwardly and also establish a desired width. The insulation assembly has the longitudinally extending tucks along each of its side edges and each of the side edges has a generally concave cross section.

Abstract: A method for making a mineral fiber insulation assembly is disclosed. The insulation assembly includes a mineral core having opposed major surfaces, opposed side surfaces and opposed end surfaces. polymer film covers only the opposed major surfaces and opposed side surfaces. One or multiple lanes of mineral fiber packs are moved along a predetermined path. At least one sheet of polymer film is supplied to the predetermined path to cover the major surfaces and side surfaces. The polymer film is attached to at least one of the core side surfaces and a plurality of openings are in the polymer film adjacent at least one side surface. The mineral fiber pack and the polymer film cover are cut perpendicular to the predetermined path to form individual ones of the mineral fiber insulation assemblies.

Abstract: Apparatus and method for concurrently determining steam flow rate and quality, through a conduit which comprises an orifice plate positioned in series with a critical flow venturi in said conduit. Pressure sensing means in the conduit senses pressures therein for application in a formula to provide the desired steam values and provide a method for determining both the quality and the mass flow rate of steam flow passing through the conduit. The measurements are of particular value in the instance of steam flow where a minimal decrease in steam pressure across the measuring instrument is a relevant factor.

Abstract: A mineral fiber insulation assembly is disclosed. The insulation assembly includes a longitudinally extending mineral fiber core having opposed major surfaces, opposed side surfaces and opposed end surfaces. A low friction polymer film is positioned adjacent the major surfaces and the side surfaces. At least one of the side surfaces is attached to the polymer film. A plurality of openings are provided in the polymer film adjacent at least one of the side surfaces. The insulation assembly is readily compressible and expandable at the job site. The low friction film provides easy installation.

Abstract: A method and apparatus for making an insulation assembly is disclosed. A plurality of mineral fibers are moved along a conveyor system after having been cut to desired sizes. A section having a major surface is moved in a direction generally normal to that of following sections, while maintaining the major surface in a plane parallel to the plane of the major surfaces of the following sections. A plurality of the individual sections move through an encapsulation module where they are assembled and covered to form the insulation assembly.

Abstract: Method and Apparatus for injection steam of know quality into a subterranean reservoir containing hydrocarbon fluids, to enhance or stimulate production of said fluids through a production well. Production stimulating steam from a pressurized source is injected into the reservoir by way of a critical flow venturi and an injection well, in a manner to maintain the steam at a desired pressure and flow rate. The venturi's constricted throat is formed as a function of the stimulating steam's original characteristics.

Abstract: A therapeutic leg elevator for promoting venous flow during patient recuperation including a substantially homogeneous solid polygonal shaped member having at least one inclined surface for supporting a back portion of a patient's thigh and second inclined surface with respect to the first for supporting the patient's lower leg, a member is releasably connected to a distal end of the homogeneous support member to provide resistance exercise for the patient.

Abstract: A balanced skeletal traction apparatus for aligning fractured leg bones of a patient lying in a supine recuperative position including an underlying solid polygon support member, a horizontal traction device operable to be connected to a patient's lower leg for providing longitudinal traction and at least one securing member operable to releasably secure a patient's leg with respect to the underlying solid polygon support member.
