A nonwoven hospital sponge material has been provided comprising a layered fabric having an inner core of a substantially hydrophilic material disposed adjacent at least one outer or surface layer or between a pair of outer layers of a substantially hydrophobic material, said sponge material being bonded by passing the material through rolls engraved in a pattern of lands and grooves in such a way...

The invention described is the coating in situ of polytetrafluoroethylene (PTFE) on interacting mechanical parts. A paste of PTFE and mineral oil is prepared and diluted with further mineral oil. The mechanical parts are operated until the parts are burnished with PTFE.

A centrifugal separator having a rotary bowl for receiving feed which forms a pool within the bowl a skimmer movably mounted to fixed structure within the bowl for removing liquid from the pool to a discharge system with an outlet external to the bowl, and adjustment means operable from outside the bowl for adjustably moving the skimmer oppositely toward and away from the bowl axis to vary the poo...

This application describes a rotation-only CT scanner with beam deflections; the deflection and the rotation being so related as to permit the derivation of absorption data in groups focussed on respective "pivot points" outside the detector locus. Data derived from different detectors, but focussed on the same pivot point, relate to groups of paths, some of which overlap, and the overlap is used ...

A package and a method to produce said package are provided comprising a wound body of strand having an outer cylindrical portion; and an elastic membrane wound about the cylindrical portion of said body, the membrane being wound to a sufficient thickness and being stretched sufficiently to partially collapse when the strand is withdrawn from the body such that the membrane captures the strand of ...

Metallic glass powder is prepared by heating a solid metallic glass body to a temperature below its glass transition temperature for time sufficient to effect embrittlement, followed by comminution of the embrittled metallic glass body.

The invention relates to a regulating arrangement in particular on packing machines for the feed of weblike packing material in register with decorations or folding indications, so-called crease lines, present on the web. In accordance with the invention the desired control is obtained by regulating the tension of the web with the help of a guide roller over which the web is passed. The speed of t...

A centrifugal separator having a rotary bowl for receiving feed which forms a pool within the bowl a skimmer movably mounted to fixed structure within the bowl for removing liquid from the pool to a discharge system with an outlet external to the bowl, and adjustment means operable from outside the bowl for adjustably moving the skimmer oppositely toward and away from the bowl axis to vary the poo...

PURPOSE:To stop a moving equipment such as an automatic storehouse and an automtic crane which move to an objective address automatically and then stop at a fixed position highly accurately by detecting the speed of the moving equipment at the fixed position and correcting the difference between the detected speed and a designed speed. CONSTITUTION:The moving equipment 1 has an arithmetic device 6...

A tire 44 having a reinforcing sheet 10 of tubular knit material stretchable during shaping into a toroidal form. The knit material provides openings 12 for striking through of the liquid reaction mixture of elastomer forming material used in molding the tire 44. The sheet 10 of knit material may be folded over spaced-apart bead ring 21, 22 and overlapped to provide multiple layers. The tire 44 is...

A laterally releasable toe unit has two laterally pivotable side jaws (11) which are held in a ski boot retaining position by a yoke (26) on which a release spring (30) acts and which can be pivoted laterally while pushing the yoke rearwardly against the spring force to release the ski boot. A toe plate (15) which is movable by a small amount in a vertical direction is arranged behind a laterally ...

Generally, the present invention relates to a resin-treated filter fabric which comprises a surface or batt layer comprised of glass fibers which is joined, by needling, to an underlayer which is comprised of mineral fibers. The present invention includes within its scope a method of manufacturing such a filter fabric.

PURPOSE:To compose a picture by an optional combination by composing a required picture from a partial picture composing table having information such as a moving distance in a picture and an enlargement ratio on the basis of an instruction from an operator. CONSTITUTION:The operator displays an original image loaded to a picture memory 5 on a monitor 8 and moves a cursor to draw an outline. Subse...

A hydraulic cement mix including hydraulic cement, aggregate, sufficient water to effect hydraulic setting of the cement, and an additive comprising mixtures of alkali and alkanolamine salts of alkylarylsulfonic acids and alpha olefinsulfonic acids, and alkali and alkanolamine salts of fatty acids, and a nonionic component selected from polyethylene glycol derivatives and diethanolamine adducts of...

An organic dispersion is prepared of an acid type fluorinated polymer comprises copolymerizing a fluorinated ethylenically unsaturated monomer and a functional monomer having an acid type functional group in an aqueous medium under an action of a polymerization initiator source to obtain an aqueous dispersion of an acid type fluorinated polymer having the functional monomer unit content of 5 to 40...

A flexible, closed-cell, foamed insulating material comprising a thermoplastic crosslinked polyolefin which can be used at temperatures from above 130 DEG C up to about 160 DEG C without its effectiveness being impaired. The insulating material is foamed and moisture-crosslinked, at least partially, from a graft polymer comprising a polyolefin or polyolefin copolymer and a vinylsilane and a cataly...

The invention relates to a flue gas-carrying pipe in which at least one layer, in particular each or the only layer, consists of fibre-reinforced concrete or of a fibre material bound in another matrix, for chimneys, characterised in that the fibres are especially glass fibres or carbon fibres, a cement-free matrix being preferred if the matrix is not fibre-reinforced concrete.
