The method includes the step of folding th...

An improved knot for attachment of withdrawal cords to tampons is provided. The knot comprises at least two closed loops around a portion of a length of absorbent material. The standing parts of the cord cross at least twice, to form a crossed portion at the base of the loops; a loop portion overlies the crossed portion when the knot is in place around the absorbent material, applying pressure to ...

For seismic monitoring of a petroleum deposit at least one signal receiving unit is fixed to an outside of a casing pipe before the casing plate is cemented in a borehole passing through the monitored zone. At least one housing, defined by projecting elements, (longitudinal members, stops), is provided along an outer surface of the casing pipe, with the where the reception unit being embedded and ...

This object is achieved by shaped articles based on polyesters, the diol component of which comprises an alkenediol having 4 to 12 C atoms in the carbon chain to the extent of 0.1 to 100 mol %, and which, after shaping, have been subjected to a treatment with ionizing radiation, the irradiated dose being in the range above 200 or 400 to not more than 2,000 kGy.

The present invention is directed to a rigid, lightweight filled resin foam having voids dispersed in a continuous phase which is formed from a polyester hybrid resin having reinforcing particles dispersed therein. The hybrid resin forms a complex cross-linked network (20) which may interact with other polymer networks in the continuous phase either by cross-linking or by forming an interpenetrati...

Doped and undoped polycrystalline and noncrystalline diamond films produced by plasma enhanced chemical transport emit electrons into a vacuum in response to an applied electrical field. The field required to create emission is less than 20 V/ mu m for doped polycrystalline films, can be in the range of 5 to 8 volts/ mu m for undoped nanocrystalline films and may be 3 volts/ mu m or less for doped...

An environmentally sealed electronics assembly. The assembly includes a flexible envelope surrounding the active electronics board. The electronics board is insertable into the envelope and with subsequent sealing provides a reenterable but environmentally sealed active electronics package. Methods of manufacturing the assembly are also described.

Surveillance of magnetically tagged articles in a control zone is effected in a noisy environment by so shielding an antenna establishing a front magnetic field in the control zone as to reduce field strength in the back field rearwardly of the control zone. Shield magnetic material has response to the field which is detectably distinct from tag material response to the field.

An article surveillance tag comprising a thin, planar, elastic substrate (5); the oscillatory circuit comprising a first and a second capacitor (C2, C3) whose electrodes are formed by conducting regions on opposite sides of the substrate, and a first pair of conductor branches (10, 11), whose branches are arranged on the opposite sides of the substrate (5), their first ends being connected to the ...

The present invention relates to a pallet with a base section (1) and a deck (4) forming a cargo-carrying surface with rectangular shape attached thereto. The invention is characterised in that the base section (1) is formed of a number of longitudinal base tubes (2, 3) consisting of square tubes of multilayered paper or cardboard, each of said base tubes (2, 3) showing a pair of vertical side wal...

These novel compounds are useful in the treatment of inflammatory and central nervous system disorders, as well as other disorders. The ...

A cementitious compsn. curing admixt. comprises: (a) a water-soluble poly(alkylene oxide) (PAO); and (b) superabsorbent material; and (c) optionally a superplasticiser, which does not interact with the PAO. Also claimed are: (1) forming a cementitious coating on a substrate comprising preparing a hydraulic cementitious mix comprising the above admixt. or a pref. form below, and applying the mixt. ...

A gear mechanism with two axially parallel drive shafts esp. for driving a double warm extruder, includes drive wheels of the same size, whose teeth are in contact with a layer central gear wheel. The mechanism has a single drive shaft which is extended and the single drive gear wheel is displaced w.r.t. the second shaft. The diameters of the two gear wheels are greater than the spacing between th...

A method and apparatus is provided for creating a composite waveform. This composite waveform is created by coding a plurality of input digital information signals. Subsequently, the plurality of coded input digital information signals are communicated over a communication medium to a digital combiner. The digital combiner combines the plurality of coded input digital information signals. Finally,...

A contact magnetic recording rigid disk file utilizes a magnetoresistive (MR) sensor for reading data recorded on the disk. The disk file may be of the liquid-bearing type of contact recording with the MR sensor supported on the trailing end of a carrier which rides on the liquid bearing. The performance of the disk file is enhanced by including means for minimizing the effect of a discovered base...
