Abstract: A molding composition is disclosed for forming in a single step a natural sandwich foam product having a cellular core and a thick, densified outer layer. A hard, particulate filler material such as fly ash is admixed with an unreacted, rigid polyurethane foam system, together with a density distribution control agent such as carbon tetrachloride which lowers the viscosity of the admixture. In molding, the mold cavity is charged with the admixture and the foam reaction is permitted to occur with the mold closed. The resultant, filled foam product has a thick outer layer formed adjacent the mold surface of substantially greater density than its core. In the densified layer, both the polyurethane and filler material components of the resultant product are concentrated to provide over three times the density of the core structure. Formulations are set forth which provide substantial layer thickness and an outer surface having a durometer hardness value of 50 or greater over the entire surface area.

Abstract: A toy milkable animal figure such as a cow which includes a chamber for liquid, an inlet to the chamber, and an outlet from the chamber. The chamber defines a flexible udder having at least one teat with an openable aperture. The aperture comprises the outlet. The udder may be manually manipulated by a child-user as by squeezing to cause release of the liquid through the aperture. The animal figure may include a pump which may be manually operable, as for example, by pumping the tail, and the inlet to the chamber may be connected by an inlet tube to the mouth of the animal which may be immersable in a source of water. The pump may include an overflow system which permits water to be pumped through a return tube in the figure and back to the source of water when the chamber is filled.

Abstract: Apparatus for opening a cassette, of the type which carries a sheet of X-ray film, to allow the film to move into processing equipment, without requiring a darkroom. The apparatus includes a lighttight housing containing inclined guides for receiving the cassette, and pins at the bottom of the space between the guides, that can engage latches on the cassette to open it. The cassette is forced against the pins by a cover on the housing, which pushes on the cassette as the cover approaches its fully closed position, so the pins unlatch the cassette which opens to allow the film sheet to drop out.

Abstract: Process for the practically total precipitation of precious metals from solutions which contain them, according to which said solutions are treated with carbon monoxide in the presence of a quantity of water or a primary or secondary alcohol at least equal in weight to the total quantity of precious metal present.

Abstract: An intimate blend of a melt-fabricable tetrafluoroethylene copolymer resin and graphite reinforcing fibers is obtained by intimately blending the resin and fibers in a mixture of water and a selected water-miscible organic solvent. Composites molded from the blend have high flexural modulus and tensile strength, and outstanding resistance to creep.

Abstract: Patent of invention "Safety Package of Toothpick Holder", comprising only one cardboard, laterally equipped with four faces (1-2-3-4) and an edge (5) for glueing at the inner part of the opposite face i.e. (4), and having, at the uppermost side, two edges (19-22) overlaying one another and another (26) with three cuttings (29) where pass a trapezoid projection (31) of another edge (30), in such a way that the foldable ears (32) of such projection (31) block the cover. Furthermore, there are, at the said edge (22), a cutting (25) in alignment with a hole (F) for the output of the toothpicks. Similar edges form the bottom.

Abstract: Fungal mycelia are grown in a medium wherein the phosphate level is only slightly above the level which will limit growth, which results in a slightly lower content of ribonucleic acid in the mycelia but which results in the cells being much more amenable to removal of ribonucleic acid by simple means such as thermal shock.

Abstract: The sensitivity to moisture of polystyrene sulfonate coatings on piezoelectric crystals in moisture detectors is unstable in the presence of acid gases. The sensitivity of these coated crystals can be stabilized by contacting the polymer with an acid gas.

Abstract: Mixtures of 1-(3,4-dichlorophenyl)-3-methoxy-3-methylurea with 2-chloro-N-isopropylacetanilide or 2-chloro-2',6'-diethyl-N-(methoxymethyl)acetanilide exhibit surprisingly high solubility in suitable solvents. This solution synergism is believed to be the result of molecular complexing of 1-(3,4-dichlorophenyl)-3-methoxy-3-methylurea with 2-chloro-N-isopropylacetanilide or with 2-chloro-2',6'-diethyl-N-(methoxymethyl)acetanilide.

Abstract: Fluid-carrying tubes for a heat exchanger are provided with internal longitudinal fins formed separately from the tube itself. One form utilizes individual elongated V-shaped strips biased radially outwardly by an annular sheet metal spring, with the tips of the fins brazed to the inner surface of the tube wall. Second and third embodiments utilize a one-piece corrugated sheet metal cylinder rather than individual strips, but with adjacent fins being almost completely severed from each other to provide sharp edge contact between the tips of the fins and the tube wall for optimum brazing. Either the fins or tube inner wall is clad with a lower-melting point material which permits furnace brazing of the fin tips to the tube wall. All three forms have longitudinally spaced holes and slots to enhance heat exchange by inducing transverse fluid flow through the fins and to allow liquid levels to equalize.

Abstract: The invention relates to a system for tracking and/or guidance of a vehicle or projectile using a correlation arrangement for comparing representations from a sensor mounted on the vehicle or projectile with a reference representation, the correlation being carried out by comparing portions of the representations and like portions of the reference representation to derive position coordinates for each of said portions and to evaluate from said position coordinates compensation signals for rotational misalignment and/or changes of scale as between the reference and subsequent representations.

Abstract: Esters of poly(tetramethylene ether) glycol are prepared by polymerizing tetrahydrofuran in a reaction mixture which contains, in addition to the tetrahydrofuran, and acylium ion precursor such as acetic anhydride, a polymeric catalyst which contains sulfonic acid groups and, optionally, a carboxylic acid such as acetic acid.

Abstract: A freshly slaughtered and skinned meat carcass has its skinned surface covered with a shroud consisting of a rectangular cloth composed of a blend of cotton and polyester fibers and held in place by skewers to cause the shroud to fit tightly against the skinned surface. The shroud is saturated with an aqueous saline solution when applied, and the fully wetted shroud is allowed to lose its moisture in the chilling room as the carcass loses its body heat.

Abstract: Continuous method of manufacturing coil type slide fasteners by forming synthetic monofilaments into a pair of uncured fastener element coils. The fastener coils are then intermeshed in coupled relation and sewn onto the adjacent edges of a pair of uncured knit tapes. The coil, sewing thread and knit tapes are each composed of the same thermosetting resin. The fastener chain is advanced at uniform tension and velocity through a pressing stage and viscous dye bath containing a dispersion type thermosoling dye. The advancing chain is then vacuumed to provide uniform deposition of the dye on the tape and coil. The chain is then dried and led through a heating zone maintained at a temperature which simultaneously fixes the dyestuffs and cures or thermosets the coil and knit tapes. Thereafter, the moving chain is washed and calendered while being maintained under tension. The continuous zipper chain is then cut to length and supplied with a slider and end stops.
