Abstract: A mattress elevating device is composed of components easily and quickly assembled and disassembled without the use of tools, the components being suitably sized for packing and transporting in a suitcase. The components comprise a pair of panel members releasably secured together to form a substantially flat mattress supporting surface and elevating means releasably mounted on the bottom of one of said members for holding the panels in an upwardly inclined raised position. The panel members are substantially rectangular in shape and of the same size and are arranged with adjacent edge portions thereof in overlapping relationship. Bolts and wing nuts are used to releasably secure the panel members together and a cross member is attached to the bottom of the top panel member and forms therewith an elongated groove for receiving the underlying edge of the other panel member and preventing movement thereof away from the bottom of the top panel member.

Abstract: The printability with ink of films made from a blend of stereoregular polypropylene and a hydrogenated hydrocarbon polymer is improved by adding to the blend a small amount of a hydrocarbon wax.

Abstract: A process for cutting a multi-filament tow into fibers of ultra-short length and narrow size distribution is provided. Initially, a multi-filament tow is passed through a bath of liquid impregnating material at elevated temperature. The impregnated tow is then passed through a die which is sized to control the quantity of material impregnating the tow and to compact the filaments of the tow into a closely packed bundle. The resulting tow is then cooled to solidify the impregnating material and to convert the tow to a rigid form. The rigid tow is then cut, yielding wafer-thin disks. The impregnating material is then stripped from the wafer-thin disks with a solvent followed by removal of the solvent, thereby yielding fibers of ultra-short length and narrow size distribution.

Abstract: New alicyclic ketoesters having the generic formula ##SPC1##Wherein R represents a hydrocarbon radical containing from 4 to 8 carbon atoms, and R' represents an alkyl radical containing from 1 to 2 carbon atoms, are prepared, in one embodiment, by condensing the methyl or ethyl ester of propane-1,2,3-tricarboxylic acid with methyl or ethyl esters of 2-bromo acids containing from 6 to 10 carbon atoms, and hydrolyzing, decarboxylating and re-esterifying the resulting cyclic keto-triesters.The new compounds have olfactory properties and are useful in the production of a great variety of perfumes.
