Abstract: The invention relates to a device for separating a flowing medium mixture into at least two fractions with differing mass density. The device comprises an inlet for the medium mixture to be separated, which connects to first separating means for separating the flowing mixture in at least a first and a second fraction, and that connect to first and second outlet means for discharging the first and second fractions. The device further comprises a feedback loop comprising second separating means between the second outlet means and the inlet means of the first separating means. The invention also relates to a method for separating a flowing medium mixture into at least two fractions with differing mass density, using the claimed device. The device and method allow to obtain a more selective separation, particularly in purifying natural gas.

Abstract: The described invention allows a do-it-yourselfer to customize a headboard to coordinate with a purchased comforter simply, quickly and inexpensively. To accomplish this, a groove is provided along the back-side of the headboard, inwardly from its outer edge, and over which a matching fabric to the comforter is stretched taut; a flexible tubing is then fit over the fabric to snugly force it into the groove, where it is further held in place by a pair of added, overlapping legs which extend to secure the headboard to the bed frame. The fabric can be easily changed at a later date, merely by unscrewing the securing legs and pulling up on the tubing in freeing the fabric from the groove.

Abstract: An improved fluidizable patient support system including an oval tank, a perforated plate received in the tank atop a plurality of spacers, a diffuser board located atop the perforated plate and sealed around its edge, a mass of granular material received atop the diffuser board, a flexible sheet removably secured around upper edges of the tank by snap fitting elements, a wheeled support pedestal for the tank which has a fluid pressure generator therewithin. Pivotal steps and side rails may be associated with the pedestal and tank respectively. A support frame may also be secured to the tank, extending thereabove to receive treatment apparatus.

Abstract: A stretcher is arranged to span an intervening space between adjacent two brackets for the installation of a sliding roof frame with a view to uniformly stretching a portion of a headlining adjacent the two brackets.

Abstract: A structural component for upholstered furniture includes a three-dimensional frame consisting of a plurality of wires which are welded together. A flexible substrate sheet and an upholstery material cover are secured together with padding held between the substrate sheet and the cover. Clips either pierce the substrate sheet or are attached to the cover and engage the border frame wires such that the upholstery is fastened to the frame. Preferably, the clips comprise extruded plastic elongated strip members having flange portions which are stitched to the material cover and snap portions which snap-fit onto the border wires.

Abstract: A seat for vehicles is described. The seat comprises a support structure for a cushion and a support structure for a seat back, as well as a respective stuffing part supported at least partially by the said structure. The main feature of this seat is that the said support structure has a cross-section having a profile such as to allow an engagement of at least partially mating surfaces, one of which pertains to the structure and the other to at least one component of the seat.
