Abstract: A portable scaffold supporting system which is removably secured to a construction wall. The portable scaffold supporting system comprises a frame having an upper end connected by an extension bar to the lower end. The upper end is comprised of a bracket which removably secures the system to any construction wall prior to, as well as after installation of the roof.

Abstract: A collapsible, corrugated damage prevention device for separating freight in transit in railroad cars, trucks, and the like is provided and includes an outer tube like member and a collapsible spreader core inside the outer tube and at right angles to the sides of the outer tube. One version provides an outer tube like member and a second tube like member inside and at right angles to the outer tube. Another version provides a U-shaped outer section with outwardly extending flanges covered with a cap sheet to provide a hollow interior. The sides of the void filler are scored to allow each side to be easily folded outwardly from the core member thus disposing the entire device in a flat configuration which can be easily stored when not in use.

Abstract: A method and product provide a highly portable, corrugated void filler for preventing damage to unitized loads has a body or core formed into an accordian shape to provide a number of aligned slots adapted to receive portions of associated cap sheets which are fitted in place to produce a rigid, lightweight product. Each cap sheet has a top flange with reversely bent layers of cardboard which provide a locking effect urging the layers apart in a spring-like fashion to retain the cap sheets securely in position after each is inserted into slots of the body member. The top flange of each cap sheet has outwardly extending portions adapted for mounting the void filler in position by suspending between loads or by fastening only when necessary to a vehicle sidewall.

Abstract: The invention provides novel phenylacetic acid derivatives of the formula: ##STR1## in which X and Y are the same or different and each represents halogen and R represents hydroxyl, alkoxy of 1 to 4 carbon atoms, a radical of formula R.sub.1 --NH--C.sub.n H.sub.2n --O--, in which n is an integer from 1 to 4 and R.sub.1 is hydrogen or an alkanoyl radical R.sub.2 CO--, in which R.sub.2 is alkyl of 1 to 4 carbon atoms, a radical of formula R.sub.4 NH--, in which R.sub.4 is hydrogen or --C.sub.m H.sub.2m OH, where m is an integer from 1 to 3, or a radical of formula: ##STR2## --OC.sub.m H.sub.2m --COOR.sub.2 or --O(CH.sub.2).sub.p --Z radical, where n, m and R.sub.2 have the meanings given above, p is 0 or 1, and Z is a saturated or unsaturated ring with 6 ring atoms, one of which can be nitrogen, and which can carry from 1 to 3 methyl radicals, and the addition salts which such a derivative which contains a salifiable basic group forms with pharmaceutically acceptable acids and a process for their preparation.
