Abstract: A hydraulic brake hose assembly has a core hose layer, a first reinforcing layer over the core hose layer, an intermediate hose layer, a second reinforcing layer over the intermediate hose layer, and an outer hose layer over the second reinforcing layer. In one embodiment, the first and second reinforcing layers have braid patterns formed in one of a 1-over, 1-under pattern or a 3-over, 3-under pattern. In another embodiment, one of the first and second reinforcing layers has a braid formed in a 2-over, 2-under pattern, and the other of the reinforcing layers has a braid formed in one of a 1-over, 1-under pattern or a 3-over, 3-under pattern.

Abstract: A multi component catalyst and catalytic cracking process for selectively producing C3 olefins. The catalyst comprises a first molecular sieve having an intermediate pore size, a second molecular sieve and, optionally a third molecular sieve having a large pore size. At least one of the channels of the second molecular sieve has a pore size index that is less than the pore size index of at least one channel of the first molecular sieve. The process is carried out by contacting a feedstock containing hydrocarbons having at least 5 carbon atoms is contacted, under catalytic cracking conditions, with the multi component catalyst. The catalyst finds application in the cracking of naphtha and heavy hydrocarbon feedstocks.

Abstract: The present invention provides novel naming and manipulation functions for user defined data structures in a data system using transaction service. In particular, in an electronics assembly engineering system having a computer subsystem in which user-defined data structures accessible to editor software have referential integrity and in which user modifications to the data structures during editing are made directly to the data structures rather than indirectly by way of a temporary file, the invention provides a method for permitting naming and manipulation of the data structures. The method includes the steps of (i) providing close, discard and rename functions for the data structures in the case where a newly-created data structure is being edited; (ii) providing close and copy functions for the data structures if an existing data structure is being edited; and (iii) excluding a save-as function for the data structures.

Abstract: Lures and decoys for hunting and fishing have proven to be more effective when they are in motion, so as to appear more life-like to the prey. Historically, this motion has been provided by means of mechanical agitation of various sorts, which can be cumbersome and expensive to implement.

Abstract: The disclosure is directed to a composition for controlling wellbore fluid and gas invasion including methods for using said composition. The composition of the invention is a flowable slurry preferably comprising about 70 to 30% by weight of magnesium oxychloride and about 70 to 30% by weight of water. The composition is a flowable slurry at composition temperatures below about 60° C. and sets to form a substantially solid mass upon reaching a composition temperature of about 60-68° C. The phase transition is rapid, thereby limiting or avoiding formation of gel states which contribute to incomplete wellbore seals. The rapid set of the slurry further avoids invasive contamination of earthen formations surrounding the wellbore. The composition has a near-linear relationship between the time required for the phase transition to occur and the composition temperature at which the phase transition occurs.

Abstract: A hose for use in automotive power steering applications is disclosed. The hose has an inner tube, at least one reinforcing layer, and a cover layer. The inner tube is formed of at least an innermost rubber layer and an adjacent thermoplastic layer. The thermoplastic layer is formed of a material with a modulus three to ten times greater than the modulus of the innermost rubber layer.

Abstract: A discovery toy/play feature apparatus, for use with water and sand, or other particulate or granular material is provided. The apparatus allows the user to play in both sand and water in such a way as to learn and discover physical and engineering principles while having fun. The play feature apparatus allows the user to bury objects in the sand and play as if the user was on a beach looking for shells or to play as if the user was an archeologist. Further the user is allowed to use the varying channels and pools to make dams and other water obstructions and learn fluid mechanics and engineering principles while having fun.

Abstract: An automated solid-phase method for the synthesis of poly (N-substituted glycines) (referred to herein as poly NSGs) taught here can be used to obtain poly NSGs of potential therapeutic interest which poly NSGs can have a wide variety of side chain substituents. Each N-substituted glycine monomer is assembled from two “sub-monomers” directly on the solid support. Each cycle of monomer addition consists of two steps: (1) acylation of a resin-bound secondary amine with an agent such as a haloacetic acid, and (2) introduction of the side-chain by nucleophilic displacement of the halogen (as a resin-bound &agr;-haloacetamide) with an excess of primary amine. The efficient synthesis of a wide variety of oligomeric NSGs using automated synthesis technology, as presented here, makes these polymers attractive candidates for the generation and rapid screening of diverse peptidomimetic libraries. The oligomers of N-substituted glycines (i.e.
