Abstract: The present invention relates to an improved concrete additive product comprising synthetic concrete reinforcing fibers packaged in a closed paper package, whereby under the influence of mechanical action in a concrete mixer, the packaging material disintegrates and the fibers are uniformly distributed throughout the fresh concrete mixture. The synthetic fibers may additionally be coated with a dispersant. The present invention also relates to the methods of using the above improved concrete additive product.

Abstract: The present invention relates to a method for modifying the properties of a concrete by introducing a solid admixture, contained in a paper package, into a fresh concrete, said solid admixture being selected from the group consisting of air-entraining admixtures, air detrainer admixture, accelerating admixture, alkali-reactivity reducer, superplasticizer, pumping aids, water-reducing admixture, corrosion inhibitor, permeability reducer, fibers, and mixtures thereof; and mixing the fresh concrete in a batch type mixer for sufficient time to cause the packaging material to disintegrate and distribute the admixture relatively uniformly throughout the fresh concrete.

Abstract: An energy loss detecting apparatus for measuring the rate of flow of the vapor phase of a bi-phase fluid flow, in the presence of an unknown quantity of the liquid phase, by separating the vapor phase from the liquid phase and producing a signal representing the vapor phase flow rate. The apparatus includes a hollow separator casing provided with a tube communicating with at least one of the inlet opening and outlet opening of the casing and facing thereinto. A wall seals the interior of the tube from the interior of the casing except at reduced diameter holes in the wall, the diameter of the holes being less than the inside diameter of the tubes at the wall. Energy loss due to a faulty steam trap is measurable by interposing the vapor flow rate measuring apparatus in a steam line between a steam consuming device and the steam trap.

Abstract: An energy loss detection system includes an apparatus (22) for measuring loss of the vapor phase of a bi-phase fluid. Such apparatus is interposable in an energy transfer circuit downstream of an energy consumer device (14), intended to take energy from the bi-phase fluid by converting the vapor phase to liquid, and upstream of a potential energy loss device (20). The apparatus includes a separator (24) for separating the vapor and liquid phases of the bi-phase fluid into separate flow paths. A probe (51) senses the flow rate of the vapor phase through the separator and produces a signal related thereto. An output apparatus (72) includes a readout device (79) responsive to the probe signal for producing a display indicative of vapor flow rate and hence of energy loss downstream of the separator.
