This invention is directed to a freight transportation system comprising a railway car for transporting freight containers including a frame, a pair of elongated longitudinally extending narrow beams carried by the frame, at least one pair of longitudinally extending rub rails mounted on the frame, the rub rails of each pair of rub rails being laterally spaced apart and including respectively outer surfaces having longitudinally spaced and laterally opposed openings therethrough, at least two pa...

Derivatives of 6-Aminopenicillanic Acid possessing antibacterial activity are disclosed.

Tetrapolymers, which can be used as adhesives and as terminating agents for lithium initiated polymerizations, are prepared by polymerizing a mixture of an oxirane, a cyclic ether, an organic acid anhydride, and a monoisocyanate in the presence of an organometal compound.

A key apparatus includes a magnetic reed switch and at least one magnet forming a magnetic portions for energizing the reed switch. the magnetic portion having a plurality of magnetic poles disposed to produce substantially parallel magnetic fluxes opposite in sense so that the reed switch is maintained open under the influence of both of said substantially parallel magnetic fluxes opposite in sense when the key is in normal position and that the reed switch is closed under the influence of one ...

A brassiere frame is made up of an elongated arcuate wire-like support element of metal or plastic and end elements of plastic engaged with the end portions of the support element and each including a socket portion in which the respective end portion of the support element is longitudinally slidable and a relatively thin tab or flange portion extending from the socket portion and being adapted to be sewn through. A brassiere frame, as aforesaid, is positioned in the usual fabric tunnel or pocke...

Synergistic mixture of (1) the reaction product of from one to two mole proportions of amino compound and one mole proportion of polyhalopolyhydropolycyclicdicarboxylic acid or anhydride and (2) salt of oxyalkylenated alcohol phosphate and amino compound.

3-(Chlorophenoxyacetyl)-2-oxazolidones are prepared by reacting a 2-oxazolidone with a chlorinated phenoxyacetyl chloride. When the oxazolidone is unsubstituted in the 5-position, presence of an acid acceptor is helpful to improve yield. The products are useful as herbicides.

Chromenopyrazol compounds having the formula ##SPC1## and a process for their preparation are disclosed. The chromenopyrazol compounds are useful as couplers in pressure-sensitive duplicating papers.

This invention is directed to novel polyfluoroalkenylalkoxy acrylate monomers represented by the formula: ##SPC1## Where "R" is H or CH.sub.3 and "R.sub.f " is a perfluorinated alkyl chain containing three to 14 carbon atoms, and polymers of these monomers which are useful in preparing oil and water repellent coatings.

A filamentary electrode of the coiled coil loose fitting overwind type for low pressure discharge lamps. The fine overwind is coiled in oversized primary turns around the permanent primary mandrel wire which in turn is coiled into non-circular, suitably oval or egg-shaped secondary turns. The overwind is thereby prevented from unscrewing from the primary mandrel wire and the need for crimping, flattening or welding the ends of the coil prior to dissolving out the temporary mandrel wires used in ...
