The bag blank is, before and behind a filling station (II), advanced forward hanging in the pressed together groove and ...

A cementitious composition useful for water-resistant construction materials, including floor underlayments, backing boards, self-leveling floor materials, road patching materials, fiberboard, fire-proofing sprays, and fire-stopping materials includes about 20 wt. % to about 75 wt. % calcium sulfate beta-hemihydrate, about 10 wt. % to about 50 wt. % Portland cement, about 4 wt. % to about 20 wt. %...

A method and material for shrink wrapping articles includes wrapping the article with a shrink wrapping material having a shrink/stretch film outer layer (12) and an inner layer of a non-woven fabric (14). The shrink/stretch film responds to heat by shrinking around the article being wrapped, while the non-woven material aerates to form bubbles (16) thus acting as a cushion between the shrink/stre...

A Raman spectrometry apparatus that is capable of measuring and compensating for variabilities in the apparatus comprises a source of substantially monochromatic radiation, means for simultaneously interfacing the radiation with a sample and a reference material, means for simultaneously acquiring at more than one wavelength a convolved Raman spectrum of the sample and a convolved spectrum of the ...

A continuous process for the production of an oriented high modulus profile is provided together with the novel profiles produced thereby. A dry polymer feedstock is melted and extruded through a die to form a profile precursor having a constant crosssection and specific dimensions. Sequential passage of the profile precursor through roller dies reduces its thickness whilst imparting molecular ori...

Macchina punzonatrice utilizzata vantaggiosamente, ma non esclusivamente, nella predisposizione di subtrati (20) per microcircuiti elettrici, quali ad esempio i fogli green-tape, presentante una tavola di supporto mobile sui due assi (x, y) del piano orizzontale in cooperazione con un elemento di punzonatura mobile secondo un asse verticale (z), almeno gli azionamenti della tavola di supporto (19)...

Heterocyclyl-substd. propanoic acids and their derivs., of formula (I), are new. R = formyl, tetrazolyl, nitrile, COOH or a gp. that can be hydrolysed to COOH; X = N or CR14; R2 = H, OH, NH2, alkylamino, dialkylamino, halo, alkyl, haloalkyl, alkoxy, haloalkoxy or alkylthio; R14 = H or 1-5 C alkyl; R3 = R2 or alkoxyimino; or CR3 + CR14 = 5 or 6 membered alkylene or alkenyl ring (opt. substd. by 1-2...

A reactor for conducting a continuous multi-phase catalytic reaction such as the conversion of syngas to higher hydrocarbon fuels. Gaseous reactants are introduced via a gas-permeable plate into a slurry which includes the product and a finely divided catalyst. The liquid product is separated from the remainder of the slurry by means of a filter unit including a filter member. A pressure different...

A disposable diaper (1) has front and rear waist regions (6,7) adapted to be separably connected to each other by surface fasteners. Each surface fastener comprises a hooked fastener component (15) and a looped fastener component (16) operatively associated with the hooked fastener component (15), and at least a pair of wings (12) extending outward from transversely opposite sides of the rear wais...

A nursery gate is provided with a pivoted latch. When the gate is swung to a closed position where it is co-planar with the keeper and hinge axis, the latch draw engages the keeper. At that time, a detent provided by the nose and the recess engages due to a spring movement of one of the part in the direction of the hinge axis. The gate is released for opening by a movement in the opposite directio...
