A process for storage of a liquefied gas on an adsorbant support in a chamber provided with at least one discharge orifice for the distribution of the gas in gaseous form into an environment at a pressure lower then the storage pressure. The adsorbant support is constituted of hollow capillary fibres, natural or synthetic, such as kapok fibers. The hollow capillary fibers have an inner diameter be...

The storage stability of otherwise unstable premix compositions for flame retardant rigid polyurethane foams containing in the premix a chlorinated polyether polyol and a tertiary amine catalyst, is enhanced by incorporation into the premix of a minor amount of a vinyl monomer. The preferred vinyl monomers employed are condensation products of acrylic or methacrylic acid with alcohols or amines. S...

The instant invention is directed to a process for the production of molded polyisocyanate-based foam products having a compact, light- and yellowing-resistant polyurethane-based top layer comprising the steps of: A. coating a mold with a liquid polyurethane-polyurea-based coating agent, containing a binder, which reacts to form a light- and yellowing-resistant top layer and B. introducing a foama...

Electronic circuitry monitors the electrical energy consumption of a system and displays the current cost of the energy usage. The projected monthly billing cost is calculated at the current rate of consumption, and an alarm signal and control output are generated if the projected cost is higher than a budget amount. Energy consumption is sensed optically at the electric meter (3) and a proportion...

1462838 Packaging flexible flat goods WINDMOLLER & HOLSCHER 6 Sept 1974 [19 Oct 1973] 39084/74 Heading B8C In a method of packaging flexible flat goods, such as bags, garbage sacks, or the like, a stack is formed from goods to be packaged and is introduced into an opened half-tube of film, and whilst partially pressing the included air, is welded therein by a separating weld seam which closes the ...

Continuous glass fiber with a polyolefin compatible sizing composed of a coupling agent, a stabilizer, a lubricant, a non-crosslinking film forming polymer, softening agent and surfactant are disclosed for utilization in polyolefin polymer reinforcement. The article formed and formation method for fiber combination with a polyolefin polymer are also disclosed.

A strand of glass fibres is impregnated with a sizing comprising (1) a coupling agent, (2) a stabilizer, (3) a lubricant, (4) a non-crosslinkable film-forming polymer and (5) a cross- linkable film-forming polymer. The resulting sized glass fibre strands have been found, to be storage stable; to form a package of sized glass fibre which is readily available for subsequent use; and to show improved...

Silica plastic compositions containing a silicate filler finely dispersed therein are produced by simultaneously adding a mixture of an aqueous solution of an alkali silicate and a coagulable latex emulsion of a plastic polymeric material and a solution of at least one salt of hydrochloric or sulfuric acids and a metal selected from the group consisting of zinc, magnesium, calcium, and maintaining...

To acquire and record the variation of a value such as a pressure as a function of a parameter such as time in a sonde (10) lowered into a well (12), pressure measurements are made at equal time intervals, these measurements are digitized and entered in a nonvolatile memory selectively so as to maximize the accuracy of the pressure variation reading during the measurement period, while minimizing ...

Effective bonding of a vulcanized composite of rubber to a brass coated steel cord is improved by the addition of small amounts of an organic polymer which contains polysulfide linkages in the backbone of the polymeric chain. Under conditions where heat and water ordinarily decrease the adhesion of the composite, rubber compounds with small amounts of the polysulfide have considerably increased ad...
