Abstract: A chair with four upright legs, each of which has a single socket, has a square frame assembled of four identical sections each having a straight central portion and two end portions bent outwardly through angles of 135.degree.. The end portions of neighboring sections have abutting toothed surfaces, and each pair of such end portions has a tip of reduced cross section which fits into one of the sockets. The seat on the frame is disposed inwardly of the legs to allow for stacking of several chairs in a small area.

Abstract: The invention concerns the use of working bodies of low density in vibratory abrasive finishing machines for the smoothing of articles of wood, particularly articles of furniture, between the undercoating and varnishing thereof. The working bodies have either the shape of angular resin-free wooden pins of a size of 4.times.4.times.30 mm and an average Shore A hardness of about 95.degree. to 100.degree. or a flat base opposite which there is a head surface corresponding to the shape of a spherical segment.

Abstract: A luggage rack which is mounted on the roof of an automotive vehicle and has two longitudinally extending parallel rod-shaped carriers and several traverses separably connected to and extending at right angles to the carriers. Each traverse has an elongated outer section and an elongated inner section which is telescoped into and is movable lengthwise and/or at right angles to the outer section. The sections of each traverse have intersecting sockets in the form of elongated open-ended slots receiving parts of the carriers so that the surface bounding the slots contact the respective carrier parts. Screws which extend through the outer sections and mate with nuts on or in the inner sections bias the sections of each traverse against each other and against the respective parts of the carriers to thereby fixedly hold the traverses in selected positions.
