This invention relates to polymers and hydrogels of polymers formed from a hydrophilic monomer of the group of dihydroxyalkyl acrylates and methacrylates, a substantially water insoluble monomer from the group of alkyl acrylates and methacrylates and preferably a minor amount of a water insoluble epoxidized alkyl acrylate or methacrylate. The hydrogels are preferably used for the formation of contact lenses, but may also be used for drug and pesticides delivery devices: dialysis, ultrafiltration...

In order to obtain a high initial stress force of the screw, in particular cap screw, in a framework made of hollow sections used as bar elements, joined at separate junction members, having connecting parts for the bar elements, whereby threaded holes are provided at the exposed ends of the connecting parts and plates with central bores are provided at the end of the bar elements, on each of the plates a cap screw with its head positioned within the bar element being inserted and screwable into...

A form for a ready-made necktie includes a form body having a pair of outwardly and rearwardly extending wings, a pair of spaced arms which extend rearwardly from the body adjacent the upper end thereof, a shaft which extends between the arms, a pin which extends rearwardly from the body in downwardly spaced relation to the arms, and a clamping member which is pivotally received on the shaft. The form body is constructed for receiving a permanently tied necktie thereon, and the clamping member o...

Described herein is cookware made from a select polyarylethersulfone. The cookware can be used in essentially all cooking oven applications. Also described is a composition suitable for making cookware wherein the composition contains greater than 50 weight percent of the polyarylethersulfone.

The invention provides a implants made of metal for the purpose of anchoring superstructures consisting of one or more crowns or parts of crowns, also made of metal, arranged in the form of bridges. In general, various metals are used for the implant and the individual parts of the superstructure. In most of the implant systems presently in use, these different metal parts are in direct, electrically conductive contact. Consequently, the possibility of the formation of galvanic cells results. Th...

A drawer of plastic has a front plate, a body part with a front face to arrange the front plate parallel to the latter and a plurality of side walls each forming a downwardly open chamber and having a front region adjacent to the front face, and elements for connecting the front plate with the side walls and including a hasp arranged in the front region of each of the side walls and having a transverse bolt, an elongated bracket having a longitudinal axis and an end provided with a fork which is...

A fluorocopolymer and film thereof exhibiting excellent transparency and mechanical strength at ambient and elevated temperatures, wherein the fluorocopolymer includes polymerized units based on ethylene (E), tetrafluoroethylene (TFE), hexafluoropropylene (HFP) and perfluoro(alkyl vinyl ether) (PFAV), wherein the molar ratio of polymerized units based on E/TFE is from 10/90 to 60/40, the content of polymerized units based on HFP is from 0.2 to 0.9 mol % based on the total number of polymerized u...

In a pipe joint made of resin, a cap nut-like pressing ring is screwed to the outer periphery of a pipe receiving port of a joint body, and presses an inner ring from the outer side of a pipe member as a result of screw advancement toward the joint body. The inner peripheral face of an annular pressing portion of the pressing ring is formed into a straight shape. The inner diameter D of the annular pressing portion is set to be 1.0 to 1.1 times, preferably, 1.01 to 1.05 times the outer diameter ...

The invention provides a pipe joint made of resin in which a predetermined pressing force in the axial direction corresponding to a fastening torque of a union nut can be obtained, and the strength of threads can be enhanced. Each of threads of an external thread portion of a joint body and an internal thread portion of a union nut is formed as an asymmetrical trapezoid, an included angle al of first flanks of the asymmetrical trapezoidal threads which contact with each other by fastening the un...

A cup made of paper material comprises a fillable interior, which is formed by a conical sleeve and a bottom. The bottom is attached with a bottom skirt and essentially liquid-tight to the sleeve at the lower end of the interior. The sleeve comprises at its upper end an outwardly formed lip. The height of the lip is greater than the height of the bottom over the standing surface of the cup at the lower edge of the bottom skirt.
