A ski safety binding is provided with a measuring system for determining the occurrence of a dangerous bending moment about a transverse axis 11 passing through the weakest point of the skier's leg lying generally somewhat above the ankle. In a first embodiment first, second and third measuring transducers 14, 15, 12 are strategically arranged between the sole of the ski boot and parts of a bindin...

Polyisocyanurate polymers containing pendant urea groups are prepared by polymerization of polyisocyanates in organic solvents employing appropriate trimerization catalysts and then end-capping the polyisocyanurate polymer with ammonia or ammonium hydroxide. These end-capped polyisocyanurate polymers which contain pendant urea groups are dispersed in polyols to yield fine particulate dispersions. ...

The releasing plate which is carried for lateral pivotal motion by a pivot pin secured to the ski and which is releasably retained in its skiing position by releasing means is comprised of two members which are adapted to be relatively slidable in the direction of the longitudinal axis of the releasing plate. The rear plate member which is supported for pivotal movement by means of said pivot pin ...

An apparatus for granulating a metal melt which comprises a closed housing having a granulating section and a collecting section for the collection of manufactured powder, the granulating including a casting box and one or more primary nozzles which form decomposing, groove-shaped gas jets which impinge against the stream of metal melt falling from the casting box to form droplets which are then t...

A metal powder of improved quality is obtained by causing molten metal held in a vessel to flow out in a smooth stream through an outlet formed at the bottom of the vessel, throwing the jet of an atomizing medium consisting of nonpolar solvents such as mineral oils, or animal and vegetable oils against the stream of molten metal thereby atomizing the molten metal, separating and recovering the pro...

The present invention relates to a process for producing polyacrylic acid salt granules easily soluble in water characterized in that a water-soluble powder of polyacrylic acid salt is granulated according to fluidized bed granulation method while an aqueous solution of the polyacrylic acid salt of a viscosity of 50-700 c.p.s. is sprayed thereon.

This invention relates to porous films having pores with polygonal cross sections and average pore diameters of about 3 to about 100 microns and the method for preparing these films. More particularly this invention relates to a porous film having pores with polygonal cross sections and average pore diameters of about 3 to about 100 microns formed from a resinous polymer of propylene and the proce...

Coated beads which exhibit anti-lumping properties upon pre-expansion and which are useful in the formation of soft expanded articles are prepared by coating initial polystyrene beads, in suspension, with a coating composition comprising styrene and a macromonomer of styrene and isoprene or styrene and butadiene, the coating compositions added to the suspension as an aqueous emulsion containing a ...

Extruded styrenic polymer foams having improved flammability characteristics are obtained when using volatile fluid blowing agents by incorporating therein a small amount (e.g., from about 0.03 to about 2 weight percent based on polymer) of a waxy material in conjunction with at least one conventional non-waxy halogenated flame retarding agent.

1. Method for producing a graphic recording of a characteristic of the periphery of a borehole, comprising the step of producing, at different borehole depth levels, a plurality of measurement signals respectively representative of said characteristic for portions of the borehole periphery which are distributed around the borehole, characterized in that it further comprises the following steps : -...

Polymer powder is dispersed in a combination of an organic solvent for the powder and sufficient water to prevent dissolution of the powder in the organic solvent. The system is heated and the powder is dissolved in the solvent-water system. Water is thereafter removed and the system concentrated.

Expandable styrene polymer particles having reduced flammability are made by incorporating from 0.1 to 15 weight percent of non-polymeric organic halogen compounds into the polymer during impregnation of the polymer particles with a blowing agent in aqueous suspension. The addition of 0.001 to 0.5 weight percent of dialkyl tin maleates or fumarates during the impregnation step produces expandable ...
