摘要:
A method of forming foam comprising: (a) providing at least a first relatively high pressure liquid comprising a first reactive component; (b) introducing into said relatively high pressure stream a liquid blowing agent composition comprising 1,3,3,3-tetrafluoropropene (HFO-1234ze) and/or HFCO-1233zd to produce a second stream at relatively high pressure and containing said blowing agent; and (c) mixing at least a portion of said third stream with a fourth stream containing a component reactive with said first component to produce a mixed reactive stream.

A technique facilitates the drilling of a wellbore by enhancing the ability to relay data. The system comprises a saver sub designed to connect a top drive unit with a wired drill pipe without requiring modification of the top drive unit. The saver sub comprises an electronics package, a battery, and an antenna coupled to a saver sub mandrel.
摘要:
A method for insulating a polymeric fabric of a shelter which comprises: applying a fabric material (e.g., a natural fabric) to at least a portion of the polymer fabric; and applying an insulation material to the natural fabric opposite to the polymer fabric or treating the polymeric fabric to allow for direct application of the insulation material. The surface treatment is either roughing, electrostatic surface treatment, chemical surface treatment, primers, adhesives, solvents, or other coatings to enhance adhesion to the insulation material.

The outer insulation of an Electrical wire cable is easily and ergonomically incised to allow ease of removal from deep within the electrical outlet box without damage. The fixed angulated guide of the tool, precisely aligns a knife through the romax as the user pulls outward from within the electrical box exposing the inner wires without damaging the electrical box, internal wires or area surrounding the box. The external circumference of the romax wire is split to such a length within the box as to facilitate ease of removal and increase the speed by which an electrician can complete the wiring of such an electrical outlet. Another function of the deep slit allows the wiring inside the romax to be exposed at the greatest allowable length inside the electrical box to facilitate ease of bending and final use of the internal wires found within the outer casing of the romax style wire by the Electrician or end user.
摘要:
An obstetrical vacuum extractor has a bell-shaped cup with an open edge in communication with a hollow stem. A plurality of apertures in the cup prevent a vacuum from being drawn within the cup when the open end is brought into contact with a fetal scalp, in the absence of a sheet liner adapted to fit within the interior of the cup, engage its open edge, and having a central hole adapted to communicate with the hollow stem so that a vacuum may be drawn within the liner. The liner surface preferably includes a foil layer and covers the apertures so that the vacuum may be drawn.
摘要:
A cleansing article is provided which includes an effervescent cleanser composition held within a water-soluble packet and the packet is held within a receptacle formed from a first and second substrate sheet. At least a portion of one of the substrate sheets must be water permeable. The effervescent cleanser composition is an intimate mixture of an acid material such as citric acid, an alkaline material such as sodium bicarbonate, and a surfactant.
摘要:
A constant resistance exercising apparatus and system comprising a series of resistance units, each comprising a storage drum, output drum, and a constant torque spring wound about each drum. Each resistance unit may be selectively actuated through a lever and clutch assembly that simply slides a gear arrangement in and out of contact with a respective output drum. Accordingly, through the effortless toggling of a lever, a user may select or deselect multiple resistance units to provide a desired quantitative and measurable level of constant resistive force. Exercise tools, including handgrips, leg cuffs, bars, and/or harnesses, may be connected to a cable extending from the resistance units, and thus, function as the interface between the exercising apparatus and the user.
摘要:
A prosthesis is provided for treating aneurysms, occlusive disease of vessels and body organs, and arterio-venous fistulas, occurring in single and bifurcated lumens. The prosthesis comprises an expandable coiled sheet portion having a biocompatible graft, either a sheet or tube, affixed thereto along part or all of the circumference of the coiled sheet portion. The prosthesis has a small delivery profile, making it suitable for use in a variety of body vessels. Methods of making and deploying the prosthesis in single and bifurcated lumens are also provided.
