The invention relates to an auxiliary pile board assembly for use in the temporary support of sheets at the delivery end of a sheet fed printing press and on which sheets are deposited during replacement of the main pile board. The assembly includes a pair of longitudinal rails of equal length spaced parallel to one another with first and second cross rails spanning the space between them. The fir...

This invention provides an odor-reducing composition comprising an antioxidant and an aliphatic hydroxycarboxylic acid compound, preferably dispersed in an inert medium. Preferably, there is provided in further combination therewith a terpene.

The power stroke of the within punch press results from the electrical interaction of an armature, attached in depending relation from a superposed positioned die set, and a solenoid coil located in the supporting base of the press. In assembling each component of the sub-assemblies consisting of the supported die set and of the supporting base, a positional relation is achieved for each component...

A winding device for a conical cross-wound coil wherein the coil is driven by peripheral friction applied to a predetermined part of the length thereof constituting a friction zone, and the thread that is to be wound on the coil is fed thereto by a thread guiding member, means for reducing the angle at which the wound threads cross on the cross-wound coil in the friction zone with respect to the t...

A tire forming drum provided with two half drums axially mobile relative to each other and arranged to support on their outer periphery tubular plies of a carcass to be formed, each half drum being arranged to produce automatic folding of the relative end of said tubular plies about a respective annular bead by means of a respective multiple air chamber element rigid at one end with an outer flang...

A method of pyrolyzing sewage sludge to transform the same into activated carbon, with the combustible pyrogas and volatile liquids included therewith that arise from the pyrolysis operation being burned to sustain the transformation operation. A first portion of the hot activated carbon resulting from the operation is mixed with the wet sewage sludge to provide a dry sludge mixture that is subseq...

Constant boiling and essentially constant boiling compositions comprising from about 99 - 72 weight percent trichlorofluoromethane, from about 0.5 - 15 weight percent isopentane and from about 0.5 - 13 weight percent methylene chloride are novel compositions which are particularly useful as blowing agents in the preparation of polyurethane foams.

A contractible segmented rigid core of a tire-curing mold is disclosed comprising a plurality of sectors, and means which permit a reduction of the transversal dimensions of the sectors to facilitate removal thereof from the cured tire, said means comprising forming each of the sectors in three parts transversely of the mold, one a central part provided with means for producing a movement under th...

Bodies are press-molded from a mixture of particulate fuel and a binder. These bodies are heated to a temperature between about 600 DEG -900 DEG C. in a rotary furnace to degas them. The degassing is carried out without subjecting the bodies to mechanical stresses and without permitting combustion of the expelled volatile gases. The resulting shaped coke has a greatly improved abrasion resistance...

Compounds of the formula wherein A is oxygen or -NH-, and R is straight or branched alkyl of 2 to 22 carbon atoms or straight or branched alkenyl of 3 to 18 carbon atoms, AND ACID ADDITION SALTS THEREOF; THE COMPOUNDS AS WELL AS THE SALTS ARE USEFUL AS ACARICIDES.

In a releasable ski binding of the type wherein a sole-plate is operatively connected to the ski by means of at least one cable tensioned by a return mechanism within the sole-plate, a winding support having two diameters intersects one end of the cable within the sole-plate so that, on release, the section of cable extending from the return mechanism winds on the periphery of the area of the wind...

Polyisocyanate prepolymers for use in preparing polyurethane products elastomers, adhesives and foams, are prepared by combining (1) organic polyisocyanate with (2) polyols which are the hydroxyl-terminated digestion products of (a) waste or scrap polyalkylene terephthalate polymers and (b) organic polyols. Polyurethane products resulting from the polyisocyanate prepolymers exhibit useful and unex...
