Abstract: An advanced tire mold has been developed which offers the advantages of reducing the level of whiskers on the surface of the tire, reduces sticking to the mold, and which facilitates enhanced gas removal. This tire mold includes a mold segment having an inner side for contacting the uncured tire, an outer side opposite to the inner side, and a plurality of vent passages which allow gas to pass from the inner side of the mold segment to the outer side of the mold segment, the vent passages comprising vent slots, wherein each vent slots have an inlet at the inner side of the mold segment, and wherein the vent slots taper from the inlets to the outer side of the mold segment. This tire mold can be comprised of multiple mold segments which can be utilized in a tire curing press.

Abstract: A retainer device for a cable used in an aircraft includes a base. A moveable member is movably connected to the base and forms a channel with the base that is adapted to receive a cable. A pad-deforming portion is defined in the moveable member, which is displaceable between an open position in which a portion, of the moveable member is separated from the base to provide access to the channel, and closed positions, in which the moveable member is releasably connected to the base. A resilient pad is located in the pad-deforming portion to contact the cable received in the channel. The resilient pad is sized to deform from a rest state to a deformed state by the pad-deforming portion during insertion thereinto. The resilient pad is held captive after insertion into the pad-deforming portion by reforming toward the rest state.

Abstract: The formation of a cream and gel is described using a biopolymer, such as a polyhydroxyalkanoate (PHA), a polylactide (PLA), a polylactideglycolide (PLGA) and a polyglycoside (PGA), or a derivative thereof, in a latex form with the addition of a binder, which is generally an amphiphilic chemical entity. An hydrophobic domain of the amphiphilic chemical entity interacts with at least one biopolymer forming a water soluble complex, while the hydrophilic domain of the amphiphilic chemical entity maintains the soluble complex in suspension in an aqueous solution, which after proper heating becomes a gel or a cream. As a result, a versatile gel or cream is created with different compositions and textures that are obtained based on the nature of the binder used and the ratio of biopolymers and binder(s).

Abstract: The present invention relates to a flexographic water based ink in which a biodegradable polymer, such a polyhy-droxyalkanoate (PHA), replaces conventional poorly or non-biodegradable organic polymeric resins for example. PHAs are used as a latex suspension in water, thus the present invention relates to a novel pigment/latex mixture. PHA in a latex form is a fluid vehicle in which all the other components necessary to provide a flexographic ink are added, i.e., pigments, wax and/or binder, as well as a solvent, if necessary. The PHAs are mainly responsible for the biodegradability of the flexographic water based ink. The present invention relates also a method to produce a flexographic water based composition with enhanced biodegradability properties.

Abstract: A method has been developed for the control of both molecular weight and molecular weight distribution of polyhydroxyalkanoates (PHAs) produced by bacterial strains. The control is exerted once the biopolymer has been accumulated intracellularly through a fermentation process by a chemical, enzymatic or irradiation treatment. More particularly, the control of both molecular weight and molecular weight dispersity is achieved by keeping the biopolymer in its native state during the whole process. This implies that no or little or no crystallization has occurred. In another embodiment, the decrease of the molecular weight can be achieved during the extraction and purification process.

Abstract: This invention relates to the use of tannin for improving the ozone fastness of dyed and undyed polyamide-containing material, which comprises applying tannin to, or incorporating it into, the polyamide-containing material.

Abstract: This invention relates to a process for the production of resists or multicolor effects on natural or synthetic polyamide fiber materials, which, to produce resists, comprises locally applying a liquid preparation wet-on-wet before or after treating the textile material with a dyeing liquor or printing paste containing at least one anionic dye, said preparation comprising one or more than one compound of formula ##STR1## wherein R.sub.1 is a straight-chain or branched C.sub.10 -C.sub.24 alkyl or alkenyl radical, R.sub.2 and R.sub.3 are each independently of the other C.sub.1 -C.sub.

Abstract: A process for preparing edible, fat-containing food products is disclosed wherein the dry ingredients of the food product are intimately mixed with a solid, particulate refrigeration agent until the food product has been chilled and refrigerated to a degree sufficient to recover a dry, granular, free-flowing, fat-containing food product therefrom. Dry ice is used in pellet form as the refrigeration agent, and it chills the fat-containing food products without freezing it. This aids in mixing of the fat of the food.
