A flexible cover for a waterbed mattress is constructed as a three-ply construction. A central ply formed of heat insulating materials is sandwiched between two similarly constructed outer plies that are formed of moisture-absorbent materials. Moisture generated by the person's body is trapped within the uppermost layer, or ply, of the cover. Body heat passes through the moisture-absorbent layer i...

A combination catheter for both detecting monophasic action potentials and ablating surface tissue in an in vivo heart of a patient is provided. The apparatus includes a catheter probe having a terminal tip portion and an electrode carried on the tip such that a portion of the tip electrode is exposed to ambient. A reference electrode is spaced along the tip from the first electrode for supplying ...

The apparatus has several carrying bars which can be spread in radial manner from a central headpiece (2) and several shielding screen elements (17, 18), which are in each case fixed between two carrying bars. The multipart construction of the carrying bars from longitudinally displaceable, interengaging bar elements (4, 5) makes it possible to slide screen elements (17, 18) over one another, so t...

A pager carrying device including a fabric woven cord having the ends crimped together at one end of a metallic crimp. The other end of the metallic crimp secures the ends of an elastic looped material. The latter being designed so that it may be expanded to readily fit over the spring biased securing clip on the rear wall of conventional beepers. In its unexpanded condition, it serves to securely...

Process for preparing MDI flexible foam in a closed mould at a pressure of 0.001-0.5 bar above atmospheric pressure.

Disclosed are foamable copolyester compositions containing 0.5 to 5.0 mole percent of a dicarboxylic acid sulfomonomer which contains at least one metal sulfonate group attached to an aromatic nucleus. These copolyesters possess high melt viscosity and are readily foamable with a wide range of foaming agents to provide low density shaped articles, films, and sheets.

A method for reduces the amount of information relating to the status of a vehicle relayed from the vehicle to a remote location over a communications data link. The method includes the steps of generating a fault code, delivering the fault code to the remote location across the data link, and receiving the fault code at the remote location and responsively generating a data request signal. The da...

A digital data system that includes a control system at a customer site that blocks access to a down-loaded stored program after it has been viewed a predetermined number of times (e.g., once), or after a predetermined interval, or any combination thereof.

A polyester composition is disclosed, which is characterized in that it contains, besides polyester, vaterite-type calcium carbonate obtainable through carbonation reaction of a calcium compound in a mixed medium of alcohol and water. The polyester composition is superior in compatibility between the polyester and the vaterite-type calcium carbonate.

There is described a method of manufacturing elastomeric thin walled articles, and thin walled elastomeric articles manufactured therefrom, which comprises dipping a suitably shaped former into an aqueous polyurethane emulsion, which emulsion comprises a substantial number of particles with a mean particle size of greater than 0.3 micrometer.

A method of determining, from surface measurements, the rate of penetration DELTA d of a drill bit attached to a drill string suspended from a floating drilling rig by means of a suspension system and a motion compensator, the method comprising: a) determining a displacement DELTA s of the drill string at the surface; b) determining from the measurements a function LAMBDA ' of drill string comp...

A composition for scavenging oxygen is disclosed. The composition comprises an ethylenically unsaturated hydrocarbon polymer which has 0.01-1.0 equivalents of carbon-carbon double bonds per 100 g of polymer and a transition metal catalyst and can be incorporated into various types of layers.
