Abstract: A novel neomorphic form of ibuprofen, processes for preparing the ibuprofen, and method for administering the ibuprofen are provided. The neomorphic form is characterized by having a distinctively less bitter taste and causes less burning sensation upon swallowing. The neomorphic form of ibuprofen contains an amorphous ibuprofen. Tests indicate that the neomorphic form is less irritating to the gastrointestinal tract of animals upon administration.

Abstract: A non-aqueous, chewable composition for oral delivery of unpalatable drugs is provided along with preparative methods therefor. The composition contains the drug intimately dispersed or dissolved in a pharmaceutically-acceptable lipid that is solid at room temperatures. The composition also has a matrix that contains a granulating agent for the total composition and a rapid dispersal agent and optionally additives such as buffering agents, flavoring agents, surfactants, and the like.

Abstract: A novel neomorphic form of ibuprofen and processes for preparing the ibuprofen are provided. The neomorphic form is characterized by having a distinctively less bitter taste and causes less burning sensation upon swallowing. The neomorphic form of ibuprofen is an amorphous ibuprofen and is prepared by imparting kinetic energy to supercooled ibuprofen.

Abstract: A novel neomorphic form of ibuprofen and processes for its preparation are provided. The neomorphic ibuprofen is characterized by having a distinctively less bitter and acidic taste commonly associated with conventional ibuprofen and which causes less burning sensation upon swallowing. The neomorphic form of ibuprofen is an amorphous ibuprofen and is prepared by resolidifying supercooled ibuprofen at a process temperature below 0.degree. C.

Abstract: Palatable liquid therapeutic microemulsion wherein a drug dissolved in propylene glycol is dispersed in fatty ester. Lecithin is the emulsifier.

Abstract: A railroad car truck bolster has a plurality of pockets each of which will position a friction wedge for use in damping motion between the bolster and the side frame. Each pocket has a slanted rear wall and adjoining side walls perpendicular thereto, the side walls being generally perpendicular to the longitudinal axis of the bolster. One of the side walls is designated the inboard side wall and the other is designated the outboard side wall. The present invention is specifically concerned with a wear plate which is positioned within the friction wedge pocket and has a main portion formed and adapted to substantially conform to the pocket slanted wall and at least one wall portion integral therewith and formed and adapted to substantially conform to the pocket outboard side wall, an area subject to substantially greater wear than the inboard pocket side wall. Further, there are elements on the wear plate for cooperative attachment of the wear plate to the pocket.

Abstract: A constant contact resilient side bearing adapted to be positioned on a railroad car truck bolster and in constant contact with the underside of the car body for retarding movement of the car truck relative to the car body includes a housing adapted to be positioned on the bolster and which may, in some applications, be integrally cast with the bolster. A pair of rollers are mounted within the housing for contact with the underside of a car body, the rollers being arranged with their axes approximately parallel to the longitudinal axis of the bolster or generally having the roller axes intersect in the center of the center plate. A resilient elastomeric pad is positioned within the housing and beneath the rollers. The pad provides resistance to movement of the rollers responsive to relative rotation between the car truck bolster and car body underside.

Abstract: Benzyl dimethyl amine is subject to electrofluorination in anhydrous HF to produce perfluoro-N,N-dimethylcyclohexylmethylamine. The obtained perfluoro compound is emulsified with the aid of a nonionic surfactant to form a stable emulsion showing promising use for administration as a blood substitute.

Abstract: A process for the manufacture of railroad car truck components with high wear resistant qualities involves an alloy of specific composition, dumping from the sand mold above a specific temperature and being allowed to cool in air, resulting in an "as cast" acicular microstructure having very little amounts of Pearlite and carbides. This process eliminates the heat treating, quenching and draw operations normally associated with the production of wear resistant, acicular castings.

Abstract: A supportive spring system particularly adaptable to vehicles such as railway cars that are operated with widely variable loads from empty to fully loaded condition. Such a spring system utilizing a plurality of helical spring units comprises multiple nested springs with primary springs having greater axial length than one or more secondary springs so that the primary springs alone provide the necessary supportive capacity to yieldingly support the weight due to an empty or slightly loaded car. When cars are heavily loaded, the secondary springs also become supportive and all sets of springs act in unison. To prevent the secondary springs from bouncing and becoming misaligned due to the vehicle's movement on the track, the lower coterminating end coils of the primary and secondary springs are yieldingly bonded together by an elastomeric material.

Abstract: A bolster for use in a stabilized railroad car truck has stabilizer pockets on each side of each end. Portions of the bolster adjacent the pockets extend above the bolster top wall. There are reinforcing means for each bolster pocket positioned generally at the midpoint of each pocket and within the bolster structure.

Abstract: A railroad car bolster with provision for elastomeric cushions or pads on each side of the bolster center plate. The pads are mounted in retainers. The side walls of the retainers extend upwardly from the bolster and have substantially continuous uninterrupted upper surfaces. The pads positioned within the retainers have elongated slots which extend along and are slightly spaced from the retainer side walls. Fastening members, in the form of angles, are welded to each retainer side wall, and have a portion thereof which extends along the flat upper surface of the side wall and into the pad slots to thereby secure the pads within the retainers.
